  • How can I prevent row selection in the WPF Toolkit DataGrid?

    - by Kilhoffer
    I see a few options available for row selection, but 'No Selection' is not one of them. I've tried handling the SelectionChanged event by setting SelectedItem to null, but the row still seems selected. If there is no easy support for preventing this, would it be easy to just style the selected row the same as an unselected one? That way it could be selected, but the user has no visual indicator.

  • Modify values on-the-fly during SqlAdapter.Fill( )

    - by Timothy
    What would the proper way be to modify values on the fly as they are loaded into a DataTable by SqlAdapter.Fill()? I have globalized my application's log messages. An integer indicating the event type and serialized data relevant to the event is stored in the database as show below. When I display the logged events through a DataGridView control to the user, I interpolate the data to a formatting string. event_type event_timestamp event_details ============================================ 3 2010-05-04 20:49:58 jsmith 1 2010-05-04 20:50:42 jsmith ... I am currently iterating through the DataTable's rows to format the messages. public class LogDataTable : DataTable { public LogDataTable() { Locale = CultureInfo.CurrentCulture; Columns.AddRange(new DataColumn[] { new DataColumn("event_type", typeof(Int32)), new DataColumn("event_timestamp", typeof(DateTime)), new DataColumn("event_details", typeof(String))}); } } ... using (SqlDataAdapter adapter = new SqlDataAdapter(...)) { adapter.SelectCommand.Parameters.AddRange(new Object[] { ... }); adapter.Fill(table); } foreach (DataRow row in table.Rows) { switch ((LogEventType)row["event_type"]) { case LogEventType.Create: row["event_details"] = String.Format(Resources.Strings.LogEventCreateMsg, row["event_details"]; break; case LogEventType.Create: row["event_details"] = String.Format(Resources.Strings.LogEventCreateMsg, row["event_details"]; break; ... The end result as displayed would resemble: Type Date and Time Details ==================================================================== [icon] 2010-05-04 20:49:58 Failed login attempt with username jsmith [icon] 2010-05-04 20:50:42 Successful login with username jsmith ... It seems wasteful to iterate the result set twice-- once as the table is filled by the adapter, and again to perform the replacements. I would really like to do the replacement on-the-fly in my LogDataTable class as it is being populated. I have tried overriding an OnRowChanging method in LogDataTable, which throws an InRowChangingEventException. protected override void OnRowChanging(DataRowChangeEventArgs e) { base.OnRowChanging(e); switch ((LogEventType)row["event_type"]) ... I have tried overriding an OnRowChanged method, which throws a StackOverflowException (I assume changing it re-triggers the method ad infinitum?). I have tried overriding an OnTableNewRow method, which does not throw an exception but appears not to be invoked (I assume only when a user adds a row in the view, which I've prevented). I'd greatly appreciate any assistance anyone can give me.

  • Adding Items to an Inner (Nested) ListView

    - by Corey O.
    I have 2 asp:ListView controls, one embedded in the other (OuterListView and InnerListView respectively). I am trying to add an asp:linkbutton in the InnerListView layout that will allow the user to add an item to the InnerListView. Unfortunately, when I handle the OnClick event in the linkbutton control, I can't figure out how to get a handle on the asp:linkbutton's parent ListView from within the codebehind handler. Obviously, there is no global handle since there are multiple inner listviews. I can link code if necessary.

  • how to declare a public string with a textbox's text

    - by Ian Lundberg
    i am trying to do public string str = txtText.Text; but it wont let me use txtText.txt so how would I declare that so it can be used everywhere? I can't use it in the button1_click event because if I do it messes it up because I am having a string retrieve from the textbox and set to the textbox so it doesn't work right so I have to have it retrieve the textbox's text somewhere else then set to it.

  • jQuery i++ and i-- problems ... what on earth???

    - by michael
    Could someone please tell me what I am doing wrong? I'm not a newbie at programming but I feel like it tonight! Every time I increment the incrementing variable it throws a fit! When add one to it, it behaves fine, but if I try to add one more to it it wants to add 2 more. And then if I try to de-increment it wants to subtract from the original number that it was assigned to. I've tried: i++; i = i+1; i = i++; Nothing seems to work. It's got to be a stupid mistake. Press the buttons to increment and de-increment. http://michaelreynolds.net/iphone/ here's the code: var dayNum = 30; //---------------------------------------------------------------------- $.jQTouch({ icon: 'dailyqoteicon.png', statusBar: false, initializeTouch: 'a.touch' }); //---------------------------------------------------------------------- $(document).ready(function(){ //$(function(){}); $(function(){ $('a.touch').swipe( function(event, info){ //alert("jQTouch swipe event"); //alert(info.direction); }); }); $(function updateVerse(){ //alert("updateVerse called"); $.ajax({ type: "GET", dataType: 'JSON', data: 'day='+ dayNum, url: 'forward.php', success: function(data){ var obj = $.parseJSON(data); $("h2.quote").html(""); $("h3.reference").html(""); $("h2.quote").append(obj.quote); $("h3.reference").append(obj.reference, " ", obj.version); //$("span.version").append(obj.version); //----------------------------------- // JSON string {"id":"1","quote":"For to me, to live is Christ, and to die is gain","reference":"Philippians 1:21","version":"NKJV"} }, error: function(request, error){ alert("problem retrieving json data string"); } }); function addDayNum(){ dayNum = dayNum + 1; //dayNum = dayNum++; } function subDayNum(){ dayNum = dayNum - 1; //dayNum = dayNum--; } $("div#header a.next").tap( function(){ addDayNum(); //dayNum++;// doesn't work at all //dayNum = dayNum + 1;//doesn't work at all updateVerse(); //alert(dayNum); //alert("next clicked"); }); $("div#header a.prev").live('click', function(){ subDayNum(); //dayNum--;//doesn't work at all //dayNum = dayNum - 1;// doesn't work at all updateVerse(); //alert(dayNum); //alert("previous clicked"); }); }); });

  • jquery buttons icons for dialog

    - by khinester
    I have this code: $(function() { var mainButtons = [ {text: "Invite" , 'class': 'invite-button' , click: function() { // get list of members alert('Invite was clicked...'); } } // end Invite button , {text: "Options" , 'class': 'options-button' , click: function() { alert('Options...'); } } // end Options button ] // end mainButtons , commentButtons = [ {text: "Clear" , 'class': 'clear-button' , click: function() { $('#comment').val('').focus().select(); } } // end Clear button , {text: "Post comment" , 'class': 'post-comment-button' , click: function() { alert('send comment...'); } } // end Post comment ] // end commentButtons $( "#form" ).dialog({ autoOpen: false , height: 465 , width: 700 , modal: true , position: ['center', 35] , buttons: mainButtons }); $( "#user-form" ) .button() .click(function() { $(this).effect("transfer",{ to: $("#form") }, 1500); $( "#form" ).dialog( "open" ); $( ".invite-button" ).button({ icons: {primary:'ui-icon-person',secondary:'ui-icon-triangle-1-s'} }); $( ".options-button" ).button({ icons: {primary:'ui-icon-gear'} }); }); // Add comment... $("#comment, .comment").click(function(){ $('#comment').focus().select(); $("#form").dialog({buttons: commentButtons}); $( ".post-comment-button" ).button({ icons: {primary:'ui-icon-comment'} }); $( ".clear-button" ).button({ icons: {primary:'ui-icon-refresh'} }); }); //Add comment // Bind back the Invite, Options buttons $(".files, .email, .event, .map").click(function(){ $("#form").dialog({buttons: mainButtons}); $( ".invite-button" ).button({ icons: {primary:'ui-icon-person',secondary:'ui-icon-triangle-1-s'} }); $( ".options-button" ).button({ icons: {primary:'ui-icon-gear'} }); }); // Tabs $( "#tabs" ).tabs(); $( ".tabs-bottom .ui-tabs-nav, .ui-tabs-nav > *" ) .removeClass( "ui-widget-header" ) .addClass( "ui-corner-bottom" ); }); ? What is the right way to add the button icons? As in my code I had to add it two times, once: $( "#user-form" ) .button() .click(function() { $(this).effect("transfer",{ to: $("#form") }, 1500); $( "#form" ).dialog( "open" ); ... and $(".files, .email, .event, .map").click(function(){ ... Could this code be improved further? I don't seem to be able to get the "transfer" effect to work correctly in a modal. I added: , close: function() { $(this).effect("transfer",{ to: $("#user-form") }, 1500); } to the $( "#form" ).dialog({ How would you go about in getting the "transfer" to work nicely when you open and close the dialog box?

  • Using jquery to prevent resubmitting form

    - by Tony
    I use jquery's .submit() to intercept user's submit event, however I found a problem. When the user single click the submit button, the form is submitted normally, but if a user deliberately fast click it multiple times, it will submit multiple times, which will cause duplicated data in the database. What's the solution for this kind of problem ?

  • Linq2SQL InfoMessage

    - by Paul Oakham
    Hi, is it possible to access the InfoMessage event handler in a Linq2SQL data context? All of our code uses these messages to display useful information to the end user and since moving to Linq2SQL I cannot figure out how to show these messages. I have checked the connection object of the data context as well as the classes properties with no luck so I'm wondering if it is possible. Thanks in advance.

  • Automaticly Change VisualState in Silverlight

    - by Matt
    If you create a simple button and then choose Edit Template - Edit a Copy, Blend will automatically generate a style area, along with all the button states (MouseEnter, MouseLeave, Pressed, etc). No where in the generated code does it say that on a "MouseOver" event, change the state to "MouseOver", but it still manages to work! How does a standard button do it? Is there some sort of AutoEventWireUp going on?
