  • [Android] ProgressBar inside SimpleAdapter

    - by lemon
    I'm trying to add a ProgressBar to my row.xml view but I can't seem to make it work I keep getting 06-09 12:44:44.802: ERROR/AndroidRuntime(1012): java.lang.IllegalStateException: android.widget.ProgressBar is not a view that can be bounds by this SimpleAdapter ArrayList arr = new ArrayList(); HashMap map = new HashMap(); map.put("progress", 10); arr.add(map); String [] fieldNames = {"progress"}; int [] fieldIds = {R.id.progress}; SimpleAdapter adapter = new SimpleAdapter(this, arr, R.layout.row, fieldNames, fieldIds); list = (ListView) findViewById(R.id.list); list.setAdapter(adapter); <ProgressBar android:id="@+id/progress" style="?android:attr/progressBarStyleHorizontal" android:max="100" android:progress="5" android:layout_width="fill_parent" android:layout_height="fill_parent" /> Does anyone have any idea what I'm missing?

  • Get controls ClientID/UniqueID between DetailsView and UpdatePanel

    - by robertpnl
    Hi guys, I like to know how to get the ClientID/UniqueID of a control inside a Detailsview controls EditItemTemplate element and when DetailsViews changing to Edit mode and DetailsView is inside a AJAX UpdatePanel. Without UpdatePanel, during PostBack I can get the ClientID's control, but now with an UpdatePanel. <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:DetailsView ID="DetailsView1" runat="server" DataSourceID="SqlDataSource1" AllowPaging="true" AutoGenerateEditButton="true"> <Fields> <asp:TemplateField> <EditItemTemplate> <asp:CheckBox runat="server" ID="chkboxTest" Text="CHECKBOX" /> </EditItemTemplate> </asp:TemplateField> </Fields> </asp:DetailsView> </ContentTemplate> </asp:UpdatePanel> As you see, the EditItemTemplate contains a Checkbox control. So i'm trying to get the ClientID of this checkbox when Detailsview is changing to the Edit mode. I need this value for handling Javascript. Catching the events ChangingMode/ChangedMode doesn't work; chkbox is null: void DetailsView1_ModeChanged(object sender, EventArgs e) { if (DetailsView1.CurrentMode == DetailsViewMode.Edit) var chkbox = DetailsView1.Rows[0].FindControl("chkxboxTest"); // <== is null } Maybe i'm using the wrong event? Someone can give me a tip about this? Thanks.

  • Queue ExternalInterface calls to Flash Object in UpdatePanel - Needs Improvement?

    - by Laramie
    A Flash (actually Flex) object is created on an ASP.Net page within an Update Panel using a modified version of the embedCallAC_FL_RunContent.js script so it can be written in dynamically. It is re-created with this script with each partial postback to that panel. There are also other Update Panels on the page. With some postbacks (partial and full), External Interface calls such as $get('FlashObj').ExternalInterfaceFunc('arg1', 0, true); are prepared server-side and added to the page using ScriptManager.RegisterStartupScript. They're embedded in a function and stuffed into Sys.Application's load event, for example Sys.Application.add_load(funcContainingExternalInterfaceCalls). The problem is that because the Flash object's state state may change with each partial postback, the Flash (Flex) object and/or External Interface may not be ready or even exist yet in the DOM when the JavaScript - Flash External Interface call is made. It results in an "Object doesn't support this property or method" exception. I have a working strategy to make the ExternalInterface calls immediately if Flash is ready or else queue them until such time that Flash announces its readiness. //Called when the Flash object is initialized and can accept ExternalInterfaceCalls var flashReady = false; //Called by Flash when object is fully initialized function setFlashReady() { flashReady = true; //Make any queued ExternalInterface calls, then dequeue while (extIntQueue.length > 0) (extIntQueue.shift())(); } var extIntQueue = []; function callExternalInterface(flashObjName, funcName, args) { //reference to the wrapped ExternalInterface Call var wrapped = extWrap(flashObjName, funcName, args); //only procede with ExternalInterface call if the global flashReady variable has been set if (flashReady) { wrapped(); } else { //queue the function so when flashReady() is called next, the function is called and the aruments are passed. extIntQueue.push(wrapped); } } //bundle ExtInt call and hold variables in a closure function extWrap(flashObjName, funcName, args) { //put vars in closure return function() { var funcCall = '$get("' + flashObjName + '").' + funcName; eval(funcCall).apply(this, args); } } I set the flashReady var to dirty whenever I update the Update Panel that contains the Flash (Flex) object. ScriptManager.RegisterClientScriptBlock(parentContainer, parentContainer.GetType(), "flashReady", "flashReady = false;", true); I'm pleased that I got it to work, but it feels like a hack. I am still on the learning curve with respect to concepts like closures why "eval()" is apparently evil, so I'm wondering if I'm violating some best practice or if this code should be improved, if so how? Thanks.

Even though update and refresh events are fired and executed, why is page not getting updated?

  • AsyncPostBackTrigger disables buttons...

    - by afsharm
    I've a simple UpdatePanel and a button outside of it. I've introduced the button as an AsyncPostBackTrigger in the UpdatePanel. UpdatePanel itself works fine but the button does not. Whenever the button is clicked, its click handler does not run just like the button is not clicked at all! Why the button is not working and how can it be fixed? UPDATE: here is the markup: <asp:UpdatePanel ID="upGridView" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:GridView ID="grdList" SkinID="SimpleGridView" DataKeyNames="Key" runat="server" AllowPaging="True" PageSize="15" AutoGenerateColumns="False" Caption="<%$ Resources: CommonResources, grdListCaption %>" EmptyDataText="<%$ Resources: CommonResources, grdListEmptyDataText %>" OnRowEditing="grdList_RowEditing" OnPageIndexChanging="grdList_PageIndexChanging" OnRowCreated="grdList_RowCreated"> <Columns> </Columns> </asp:GridView> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnDelete" EventName="Click" /> <asp:AsyncPostBackTrigger ControlID="btnNew" EventName="Click" /> <asp:AsyncPostBackTrigger ControlID="btnForward" EventName="Click" /> </Triggers> </asp:UpdatePanel> <asp:Button ID="btnDelete" runat="server" SkinID="Button" Text="<%$ Resources: CommonResources, btnDelete %>" OnClick="btnDelete_Click" /> <asp:Button ID="btnNew" runat="server" SkinID="Button" Text="<%$ Resources: CommonResources, btnNew %>" OnClick="btnNew_Click" /> <asp:Button ID="btnForward" runat="server" SkinID="Button" meta:resourcekey="btnForward" OnClick="btnForward_Click" />

  • Refresh a control on the master page after postback

    - by Andreas
    Hi all! What i am trying to do here is to show a couple of validation messages in form of a bulletlist, so i have a Div on my master page containing a asp:bulletlist. Like this: <div> <asp:BulletedList ID="blstValidationErrorMessage" runat="server" BulletStyle="Disc"> </asp:BulletedList> </div> When i then click the Save button from any of my pages (inside the main contentPlaceHolder) i create a list of messages and give this list as datasouce like this: blstValidationErrorMessage.DataSource = validationMessageCollection; blstValidationErrorMessage.DataBind(); The save button is located inside an updatepanel: asp:UpdatePanel runat="server" ID="UpdatePanel" ChildrenAsTriggers="true" UpdateMode="Conditional" Nothing happens, i can see that the datasource of the bulletlist contains X items, the problems must arise because the Save button is inside an update panel and the elements outside this updatepanel (master page controls for example) is not refreshed. So my question is, how do i make the bulletlist refresh after the postback? Thanks in advance.

  • nested updatepanels

    - by Elenor
    When I put nested updatepanels in outer updatepanel, then in code, it shows that outer panel is around the code of all nested panels while design mode shows outer updatepanel is drawn like one row on top of page and nested updatepanels are drawn below that outside of outer updatepanel. Is this normal behavior or there is some problem in my implementation?

  • How to use an UpdatePanel inside a Reapeater ItemTemplate with a HTML Table

    - by vanslly
    I want to allow the user to edit by data by row, so only need content updated by row. I managed to achieve this by using a Repeater with a UpdatePanel in the ItemTemplate. Using a div <asp:ScriptManager ID="ctlScriptManager" runat="server" /> <asp:Repeater ID="ctlMyRepeater" runat="server"> <ItemTemplate> <div> <asp:UpdatePanel ID="ctlUpdatePanel" runat="server"> <ContentTemplate> <asp:Label ID="lblName" runat="server" Text='<%# Eval("Name") %>' /> <asp:LinkButton ID="btnRename" runat="server" CommandArgument='<%# Eval("ID") %>' CommandName="Rename">Rename...</asp:LinkButton> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnRename" EventName="Click" /> </Triggers> </asp:UpdatePanel> </div> </ItemTemplate> </asp:Repeater> But, I want to use a table to ensure structure and spacing and CSS styling wasn't doing it for me, but when I use a table everything goes whacky. Using a Table <asp:ScriptManager ID="ctlScriptManager" runat="server" /> <table> <asp:Repeater ID="ctlMyRepeater" runat="server"> <ItemTemplate> <asp:UpdatePanel ID="ctlUpdatePanel" runat="server"> <ContentTemplate> <tr> <td> <asp:Label ID="lblName" runat="server" Text='<%# Eval("Name") %>' /> </td> <td> <asp:LinkButton ID="btnRename" runat="server" CommandArgument='<%# Eval("ID") %>' CommandName="Rename">Rename...</asp:LinkButton> </td> </tr> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnRename" EventName="Click" /> </Triggers> </asp:UpdatePanel> </ItemTemplate> </asp:Repeater> </table> What's the best way to solve this problem? I prefer using a table, because I really want to enfore structure without reliance on CSS. Thanks in advance.

  • Multiple ajax request and progress bar

    - by hunt
    Hi, In a following piece of code i am create a progress bar and showing its progress as the ajax request get processed. i am faking the progress shown here just by adding 5 in to cnt counter variable after that i made a check when counter reach to 90. at this point if the request is not executed successfully then i will pause/disable the progress bar and whenever response come i will complete the whole progress bar with 100. now the problem is i want to add multiple progress bar as i am firing multiple ajax request. so following is the code to implement only for one request and one progress bar but i want it for more than one. as global variables are used over here for checking response and timer id so i don't know how well i can handle it for multiple request var cnt=0; var res=null; function getProgress(data){ res=data; } var i =0; $('#start').click(function(){ i = setInterval(function() { if(res!=null) { clearInterval(i); $("#pb1").progressbar( "option", "value", cnt=cnt+100 ); } var value = $("#pb1").progressbar("option", "value"); if(value >=90 && res==null){ $("#pb1").progressbar("option", "disable"); } else{ $("#pb1").progressbar( "option", "value", cnt=cnt+5 ); } },2500); $.ajax({ url: 'http://localhost/beta/demo.php', success: getProgress }); }); $("#pb1").progressbar({ value: 0 , change: function(event, ui) { if(res!=null) clearInterval(i); } });

  • Why can't I put a jquery-ui progressbar inside a div with fixed position?

    - by Matthew
    I started the source from this progressbar example, and it works fine. My only change was to set the width of the progressbar to "20%". <!DOCTYPE html> <html> <head> <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script> <script> $(document).ready(function() { $("#progressbar").progressbar({ value: 37 }).css({ width : "20%"}); }); </script> </head> <body style="font-size:62.5%;"> <div id="progressbar"></div> </body> </html> I then put the progressbar inside another div, and used css to fix that div in the upper-right-hand corner. <!DOCTYPE html> <html> <head> <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/> <style type="text/css"> #testContainer { position : fixed; top : 6; right : 6; } </style> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script> <script> $(document).ready(function() { $("#progressbar").progressbar({ value: 37 }).css({ width : "20%"}); }); </script> </head> <body style="font-size:62.5%;"> <div id="testContainer"> <div id="progressbar"></div> </div> </body> </html> The progressbar becomes a slim vertical line on the left side of the screen. What am I doing wrong? I'm new to web development in general, and jquery in particular, so please forgive me if this is a stupid question.

  • Issue with Multiple ModalPopups, ValidationSummary and UpdatePanels

    - by Aaron Hoffman
    I am having an issue when a page contains multiple ModalPopups each containing a ValidationSummary Control. Here is the functionality I need: A user clicks a button and a Modal Popup appears with dynamic content based on the button that was clicked. (This functionality is working. Buttons are wrapped in UpdatePanels and the partial page postback calls .Show() on the ModalPopup) "Save" button in ModalPopup causes client side validation, then causes a full page postback so the entire ModalPopup disappears. (ModalPopup could disappear another way - the ModalPopup just needs to disappear after a successful save operation) If errors occur in the codebehind during Save operation, messages are added to the ValidationSummary (contained within the ModalPopup) and the ModalPopup is displayed again. When the ValidationSummary's are added to the PopupPanel's, the ModalPopups no longer display correctly after a full page postback caused by the "Save" button within the second PopupPanel. (the first panel continues to function correctly) Both PopupPanels are displayed, and neither is "Popped-Up", they are displayed in-line. Any ideas on how to solve this?

  • ASP.NET AJAX or jQuery (UpdatePanel/ScriptManager or UFrame/jQuery.ajax)

    - by Mark Redman
    Hi, We use the asp.net UpdatePanel and the ScriptManager/ScriptManagerProxy for ajax related functionality; reducing full page refreshes and calling WCF Services respectively. we also use jQuery and plugins for some parts of the UI. We have had some issues with javascript library related conflicts, but have come across some posts indicating that there is a lot more overhead using the UpdatePanel. I have found some limited reference to UFrame: http://www.codeproject.com/KB/aspnet/uframe.aspx www.codeplex.com/uframe Is this a commercially viable replacement for the asp.net UpdatePanel? We use a ScriptManagerProxy to reference WCF services and easily create and use a proxy to call the various WCF service methods. Would using jQuery ajax be a more efficient solution here? We have got this working well on various browsers but now seem to be getting some security related issues (as seen in FF Firebug: Access to restricted URI denied" code: "1012) which seem to have started since using jQuery a lot more. Is it possible/viable to not use ASP.NET Ajax at all?

  • ASP.NET Performance tip- Combine multiple script file into one request with script manager

    - by Jalpesh P. Vadgama
    We all need java script for our web application and we storing our JavaScript code in .js files. Now If we have more then .js file then our browser will create a new request for each .js file. Which is a little overhead in terms of performance. If you have very big enterprise application you will have so much over head for this. Asp.net Script Manager provides a feature to combine multiple JavaScript into one request but you must remember that this feature will be available only with .NET Framework 3.5 sp1 or higher versions.  Let’s take a simple example. I am having two javascript files Jscrip1.js and Jscript2.js both are having separate functions. //Jscript1.js function Task1() { alert('task1'); } Here is another one for another file. ////Jscript1.js function Task2() { alert('task2'); } Now I am adding script reference with script manager and using this function in my code like this. <form id="form1" runat="server"> <asp:ScriptManager ID="myScriptManager" runat="server" > <Scripts> <asp:ScriptReference Path="~/JScript1.js" /> <asp:ScriptReference Path="~/JScript2.js" /> </Scripts> </asp:ScriptManager> <script language="javascript" type="text/javascript"> Task1(); Task2(); </script> </form> Now Let’s test in Firefox with Lori plug-in which will show you how many request are made for this. Here is output of that. You can see 5 Requests are there. Now let’s do same thing in with ASP.NET Script Manager combined script feature. Like following <form id="form1" runat="server"> <asp:ScriptManager ID="myScriptManager" runat="server" > <CompositeScript> <Scripts> <asp:ScriptReference Path="~/JScript1.js" /> <asp:ScriptReference Path="~/JScript2.js" /> </Scripts> </CompositeScript> </asp:ScriptManager> <script language="javascript" type="text/javascript"> Task1(); Task2(); </script> </form> Now let’s run it and let’s see how many request are there like following. As you can see now we have only 4 request compare to 5 request earlier. So script manager combined multiple script into one request. So if you have lots of javascript files you can save your loading time with this with combining multiple script files into one request. Hope you liked it. Stay tuned for more!!!.. Happy programming..

  • Splashscreen ProgressBar in Eclipse RCP has "dirty" corners

    - by pimpf0r
    Hi there, I am using the RCP Splash Screen along with the built-in ProgressBar (AbsolutePositionProgressMonitorPart). The splash image has a blue background color, but the background of the progressbar seems to be white, which leads to some white corners. There is no "setBackground" on BasicSplashHandler nor does getContent().setBackground(Color) has any noticeable effect. I don't want to be too picky, but since the splash is the first thing you see from the application, I think its very important to be tidy. So, do you have any idea how to get rid of these corners?
