  • ASP.NET binding object to Request in asp.net mvc

    - by Alxandr
    I've created a object that I'd like to have accessible from wherever the request-object is accessible, and to "die" with the request, more or less like how you always in a mvc-application has access to the RouteData-collection. Especially it's important that I have access to this object in the execution of action-filters. And also there need to be created a new object of my class whenever a new request is made to the page (the object needs to be request-safe, ie. only one request modifies that one object). Any thoughts about how to achieve this?

  • jndi binding on jboss4.2.3 and ejb3

    - by broschb
    I am trying to deploy a stateless ejb on jboss 4.2.3 using ejb3 annotations. Everything builds and deploys correctly, and I do not get any errors when jboss starts up. However the ejb is not getting bound to any JNDI location for lookup when I look at the bindings in jboss. Below is what I have for my ejb. Remote @Remote public interface TestWebService { public String TestWebMethod(String param1, String param2); } Stateless EJB @Stateless @RemoteBinding(jndiBinding="TestWeb") @Remote(TestWebService.class) public class TestWebServiceBean implements TestWebService{ public String TestWebMethod(String param1, String param2) { System.out.println("HELLO "+param1+" "+param2); return "Welcome!!"; } } I have tried not having the @Remote and @RemoteBinding and it doesn't make a difference. I have also added and ejb-jar.xml file (which should not be needed with ejb3) and that does not appear to make a difference. Below is the output I see in the jboss log on startup. installing MBean: jboss.j2ee:ear=ejb_web_service_ear-0.0.1- SNAPSHOT.ear,jar=ejb_web_service-0.0.1-SNAPSHOT.jar,name=TestWebServiceBean,service=EJB3 with dependencies: 21:56:00,633 INFO [EJBContainer] STARTED EJB: com.tomax.ejb.TestWebServiceBean ejbName: TestWebServiceBean

  • Binding a Button to a GridView

    - by Tyler
    This a pretty simple question, I'm just not sure how to do it exactly. I would like to bind a Button or perhaps ImageButton to a GridView in ASP.NET/C#. Currently, the GridView has two columns and is bound to a DataTable with two columns. I want to add a third column to the GridView, which will include the Button. I know GridView has ButtonField, but I'm not too sure how to go about using it to do what I want. I want to dynamically generate these Buttons and add them to the GridView. Here is how my GridView looks right now: <asp:GridView ID="GridView1" Runat="server"> <Columns> <asp:HyperLinkField HeaderText="Display Name" DataNavigateUrlFields="DISPNAME" DataNavigateUrlFormatString="ViewItem.aspx" DataTextField="DISPNAME"> <ItemStyle Width="70%" /> </asp:HyperLinkField> <asp:BoundField DataField="TypeDisp" HeaderText="Type"> <ItemStyle Width="20%" /> </asp:BoundField> </Columns> </asp:GridView>

  • DataGridCheckBoxColumn immediate binding

    - by Johan Zell
    Hi. I'm using the WPF Toolkit Datagrid and have one column which is a DataGridCheckBoxColumn bound to a bool property on my ViewModel. My problem is that I wan't the property to get it's value updated immediately when the user checks or unchecks the checkbox. Now you have to navigate away from the cell in order to have the property updated. It's a checkbox. It can't be in the middle of editing like a textbox can... Any help would be appreciated. /J

  • C# Working with Linq binding

    - by Isuru
    I have designed Types as follow: class Cricket { string type; Team tm; public Team Team { get { return tm; } set { tm = value; } } public string Type { get { return type; } set { type = value; } } } class Team { string country; Players plr; public Players Players { get {return plr; } set { plr = value; } } public string Country { get { return country; } set { country = value; } } } class Players { string name; DateTime dob; int run; public string Name { get { return name; } set { name = value; } } public DateTime DOB { get { return dob; } set { dob = value; } } public int Run { get { return run; } set { run = value; } } } I have to get the following using LINQ techniques. 1) Youngest all data of the youngest player among all teams 2) Oldest Player of each team 3) The highest run scorer will receive Gold Medal,rest of the players of all team will receive Silver medal. (Please look at the GetPlayer() i have declared var Medal=new String[] {"Gold","Silver"} to associate the Medal ) public void GetPlayer() { var TeamMatrix = new Cricket[] { new Cricket{ Type="Twenty20", Team=new Team{ Country="England", Players=new Players{ DOB=Convert.ToDateTime("01/Jan/1989"), Name="Russel", Run=45}}}, new Cricket{ Type="Twenty20", Team=new Team{ Country="England", Players=new Players{ DOB=Convert.ToDateTime("01/Jan/1991"), Name="Joel", Run=56}}}, new Cricket{ Type="Twenty20", Team=new Team{ Country="Australia", Players=new Players{ DOB=Convert.ToDateTime("01/Jan/1990"), Name="Clark", Run=145}}}, new Cricket{ Type="Twenty20", Team=new Team{ Country="Australia", Players=new Players{ DOB=Convert.ToDateTime("01/Jan/1971"), Name="Bevan", Run=156}}} }; var Medal = new string[] { "Gold", "Silver" }; var tm = (from mat in TeamMatrix select new { mat.Team.Players.DOB }).Max(); Console.WriteLine("Youngest Age={0}",tm); } When I declare var tm = (from mat in TeamMatrix select new { mat.Team.Players.DOB }).Max(); I receive error atleast one object must implement IComparable. What is the actual way to complete the above three tasks? ( Tasks 1 ,2 ,3 are explained above). Thanks to all.

  • Boost binding a function taking a reference

  • Jquery click bindings are not working correctly when binding multiple copies

    - by KallDrexx
    I seem to have an issue when creating copies of a template and tying the .click() method to them properly. Take the following javascript for example: var list; // Loop through all of the objects var topics = data.objects; for (x = 0; x < objects.length; x++) { // Clone the object list item template var item = $("#object_item_list_template").clone(); // Setup the click action and inner text for the link tag in the template var objectVal = objects[x].Value; item.find('a').click(function () { ShowObject(objectVal.valueOf(), 'T'); }).html(objects[x].Text); // add the html to the list if (list == undefined) list = item; else list.append(item.contents()); } // Prepend the topics to the topic list $("#object_list").empty().append(list.contents()); The problem I am seeing with this is that no matter which item the user clicks on in the #object_list, ShowObject() is called with the last value of objectVal. So for example, if the 3rd item's <a> is clicked, ShowObject(5,'T'); is called even though objects[2].Value is successfully being seen as 2. How can I get this to work? The main purpose of this code is to take a variable number of items gotten from a JSON AJAX request, make copies of the item template, and insert those copies into the correct spot on the html page. I decided to do it this way so that I can keep all my HTML in one spot for when I need to change the layout or design of the page, and not have to hunt for the html code in the javascript.

  • dynamical binding or switch/case?

    - by kingkai
    A scene like this: I've different of objects do the similar operation as respective func() implements. There're 2 kinds of solution for func_manager() to call func() according to different objects Solution 1: Use virtual function character specified in c++. func_manager works differently accroding to different object point pass in. class Object{ virtual void func() = 0; } class Object_A : public Object{ void func() {}; } class Object_B : public Object{ void func() {}; } void func_manager(Object* a) { a->func(); } Solution 2: Use plain switch/case. func_manager works differently accroding to different type pass in typedef _type_t { TYPE_A, TYPE_B }type_t; void func_by_a() { // do as func() in Object_A } void func_by_b() { // do as func() in Object_A } void func_manager(type_t type) { switch(type){ case TYPE_A: func_by_a(); break; case TYPE_B: func_by_b(); default: break; } } My Question are 2: 1. at the view point of DESIGN PATTERN, which one is better? 2. at the view point of RUNTIME EFFCIENCE, which one is better? Especailly as the kinds of Object increases, may be up to 10-15 total, which one's overhead oversteps the other? I don't know how switch/case implements innerly, just a bunch of if/else? Thanks very much!

  • WPF update binding in a background thread

    - by Mark
    I have a control that has its data bound to a standard ObservableCollection, and I have a background task that calls a service to get more data. I want to, then, update my backing data behind my control, while displaying a "please wait" dialog, but when I add the new items to the collection, the UI thread locks up while it re-binds and updates my controls. Can I get around this so that my animations and stuff keep running on my "please wait" dialog? Or at least give the "appearance" to the user that its not locked up?

  • Binding value for NSTableView, but tooltip gets set as well

    - by Mark
    I've set up an NSTableView in Interface Builder to be populated from an NSArray. Each value of the array represents one row in the table. The value is bound correctly, but as a side effect, the table cell's tooltip is set to the string representation of the bound object. In my case, the NSArray contains NSDictiorany objects and the tooltip looks like it could be the [... description] output of that dictionary. Very ugly... I don't want the tooltip to be set at all. I have other tables that have plain NSString values bound to them and they don't have a tooltip set automatically. Is there some Interface Builder magic going on? I tried to start with a blank project - same problem. I should add that the table cell is a custom implementation of NSTextFieldCell that uses an NSButtonCell instance to draw an image and a label into the table. The values are retrieved from the dictionary bound as value. Why is the tooltip set when I only bind the "value" attribute? Thanks in advance!

  • jquery binding multiple events, and pass data

    - by mkoryak
    I know we can have this in 1.4: $("a").bind({ click : clickFn, mouseover: mouseFn }); and that is nice and i would like to use it, but it seems like there is no way to pass extra data to events bound this way, it needs to be done the 'old way': $("a").bind("click", {"some":"data"}, clickFn); Question: how can i pass the extra data to my event call backs and bind multiple events in a single bind at the same time?

  • Binding Entity Framework Collections Simply Using ASP.NET MVC

    - by jpcmorton
    To begin with: Using Entity Framework v4.0. ASP.NET MVC 2.0. Visual Studio 2010. I have a model that consists simply of an order & order items. What I want to do is simply bind that model without too much hassle where possible (avoiding type converters, etc). Simply the model looks like this: public class Order { public int ID { get; set; } public string OrderNumber { get; set; } public EntityCollection<OrderItem> Items { get; set; } } public class OrderItem { public int ID { get; set; } public string Qty { get; set; } } This is as simple as I want to keep it. This model is coming directly from the code generated by the entity framework generator. I would prefer to use the model directly from the entity framework (I know there are views saying this is a bad thing, but alas). I then have the View looking like this: <% using (Html.BeginForm()) {%> <%: Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%: Html.LabelFor(model => model.ID) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.ID) %> <%: Html.ValidationMessageFor(model => model.ID) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.OrderNumber) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.OrderNumber)%> <%: Html.ValidationMessageFor(model => model.OrderNumber)%> </div> <div id="lineItems"> Where I need to put my line items to be edited, inserted </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %> What I want to do is have a situation where I can use dynamic line items (using javascript). Problems are this: How to go about inserting the initial line item (within the lineItems div). This need to be strongly typed and use the built in validation framework of MVC. Best way to go about inserting line items dynamically so that on the postback there is a complete bind to the model without too much messing around (id = 1,2,3,4, etc). Any help, examples, tips, etc would be appreciated.

  • Reading Values Returned by SQLDataSource Before Binding to FormView

    - by peter.newhook
    I have a FormView that shows posts by users. I'd like to add Edit and Delete commands to the post to let the original author edit or delete their post. I'd like these commands to be available to only the author. The FormView is populated by a SqlDataSource that uses a stored procedure. I was thinking I would set the Edit and Delete hyperlink to Visible=False, then compare the currently signed in user guid to the guid of the post's author, and make the hyperlinks visible if the two guids are the same. I've tried using the Selected event of the SqlDataSource to capture the guid (which is returned by the stored procedure) however I can't find way to get the values returned by this datasource. How do I access the values returned by a SqlDataSource before they get databound?

  • port binding "problem" with Eclipse, Java, & Windows

    - by Jay
    Hi All, I use eclipse to develop a web based java application. My normal course of business is grab the next task tracking ticket. If there is a problem that needs to correcting, I run the application locally, which loads of a Jetty webserver, and binds to port 8080. After verifying the problem, I fix the problem, rebuild, and the re-run the application. The problem is, I far too often forget to close the jetty server before re-running. This generates the Java bind error: WARNING: failed [email protected]:8080: java.net.BindException: Address already in use: JVM_Bind I work in Windows, and was looking to see if there is command I could run to un-bind the port, but couldn't find an answer there. Does anyone here have a good idea of how to fix my problem, other than remember to shut down the old jetty instance before starting a new one? Thanks, Jay

  • WPF: Binding an integer to a TextBlock with TemplateBinding

    - by haagel
    I have a custom control in WPF. In this I have a DependencyProperty of the type integer. In the template for the custom control I have a TextBlock, I and would like to show the value of the integer in the TextBlock. But I can't get it to work. I'm using TemplateBinding. If I use the same code but change the type of the DependencyProperty to string it works fine. But I really want it to be an integer for the rest of my application to work. How can I do this? I've written simplified code that shows the problem. First the custom control: public class MyCustomControl : Control { static MyCustomControl() { DefaultStyleKeyProperty.OverrideMetadata(typeof(MyCustomControl), new FrameworkPropertyMetadata(typeof(MyCustomControl))); MyIntegerProperty = DependencyProperty.Register("MyInteger", typeof(int), typeof(MyCustomControl), new FrameworkPropertyMetadata(0)); } public int MyInteger { get { return (int)GetValue(MyCustomControl.MyIntegerProperty); } set { SetValue(MyCustomControl.MyIntegerProperty, value); } } public static readonly DependencyProperty MyIntegerProperty; } And this is my default template: <Style TargetType="{x:Type local:MyCustomControl}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:MyCustomControl}"> <Border BorderThickness="1" CornerRadius="4" BorderBrush="Black" Background="Azure"> <StackPanel Orientation="Vertical"> <TextBlock Text="{TemplateBinding MyInteger}" HorizontalAlignment="Center" /> </StackPanel> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> What am I doing wrong? Thanks // David

  • asp.net mvc default model binding problem

    - by csetzkorn
    I have some problems with ASP.NET MVC’s default model binder. The View contains HTML like this: <input name="SubDTO[0].Id" value="1" type="checkbox"> <input name="SubDTO[1].Id" value="2" type="checkbox"> This is my simplified ‘model’: public class SubDTO { public virtual string Id { get; set; } } public class DTO { public List<SubDTO> SubDTOs { get; set; } public DTO() { SubDTOs = new List< SubDTO>(); } } All this works fine if the user selects at least the first checkbox (SubDTO[0].Id). The controller ‘receives’ a nicely initialised/bound DTO. However, if the first check box is not selected but only, for example, SubDTO[1].Id the object SubDTOs is null. Can someone please explain this ‘strange’ behaviour and how to overcome it? Thanks. Best wishes, Christian
