[Solved] treeNode.startEdit() JS not working in IE8 with AjaxManager

BTW this works fine in Firefox but not in IE7 or 8.

I have a TreeView with ContextMenu's that call the following JS:

    
            function onClientContextMenuItemClicking(sender, args) { 
        
                    var menuItem = args.get_menuItem(); 
        
                    var treeNode = args.get_node(); 
        
                    menuItem.get_menu().hide(); 
        
                    switch (menuItem.get_value()) { 
        
                        case "rename": 
        
                            treeNode.startEdit(); 
        
                            break; 
        
                    } 
        
                }

I also have a RadAjaxManager so that this treeview triggers another panel:

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> 
        
                <AjaxSettings> 
        
                    <telerik:AjaxSetting AjaxControlID="RadTreeViewDockets"> 
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="PanelViewArea" LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                </AjaxSettings> 
        
            </telerik:RadAjaxManager>

In IE8, when I hit the Rename Context menu, for an instant the node appears editable but then it immediately looses focus and is not editable. I also tried wrapping both the TreeView and the other Panel in a RadAjaxPanel but had the same result.

Not sure if this is a bug or if there is a workaround.. Thanks!

Using SelectedIndexChanged to update second grid

I am working with the web mail demo and removing the LINQ references and trying to work within the confines of the code behind.

I have the treeview on the left updating the grid in the top right (radgrid1) properly. When I click on a gridrow in the top right (radgrid1), I want to display detail text in the bottom right pane (radgrid2). I don't care what control displays it, It will just be text.

I thought selectedindexchanged on radgrid1 would get me there but it appears to be a page lifecycle issue perhaps? I have confirmed this event is firing.

    
                Protected Sub RadGrid1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.SelectedIndexChanged 
        
                    RadGrid2.Rebind() 
        
                End Sub

Any ideas?

Filter problem - InvalidCastException

Hi.

I made MDX query with AdomdClient. I put result into DataSet and DataSet binded to Grid: RadGrid1.DataSource = dataset.Tables[0];

Grid loads data fine, paging works fine too, but Ive problem with filtering:

a] EnableLinqExpression = true

* filtering string works perfect

* filtering number gets InvalidCastException -> The specified cast is not valid. (translated by google) - error message in the end of post

* didnt try another datatypes (like date etc)

b] EnableLinqExpression = false

* when I press filter button, page is reloaded, but there is no filter applied.

Im totally lost, have no idea what to try next. Id be grateful for every idea.

Thank you!

[Solved] Close Radwindow with button in ContentTemplate

Hi,

I'm trying to close a RadWindow using a button defined in the RadWindow's ContentTemplate, but I'm having trouble getting a reference to the RadWindow object using my GetWindow() javascript function. It's the same GetWindow function that I use in other RadWindows (and that's used in various Telerik examples) and it works fine, except in those scenarios I'm using the NavigateURL property instead of ContentTemplate.

I'm using Firefox right now, so I expect the first part of the if-clause in the GetWindow() function to execute, but instead it drops down into the else-clause and then I get a frameElement is null error (since it's Firefox I assume.) But really the first part of the if-clause should be executing.

Here is a sample:

Thanks for your help, -Scott

ASP:

    
                    <telerik:RadWindowManager Skin="WebBlue" ID="RadWindowManager2" onAutoSize="true" Behaviors="Close" VisibleStatusbar="false" runat="server"> 
        
                        <Windows>

[Solved] Button inside RadInput

I am trying to create a search input with the button inside of it, just like the search box in the www.microsoft.com page. I got the code from this page to do this.
http://www.telerik.com/community/code-library/aspnet-ajax/input/how-to-create-a-button-inside-a-radtextbox-ui.aspx

I am using my own custom theme for the telerik controls, including RadInput. My one-of-a-kind textbox I need for search does not come up the way I want it, it takes all its look from the telerik theme.

Thanks for any help.
