Context menu won't display

I have an asp.net page that has a Treeview control. The Treeviwe control consists of "Controller" nodes and "Reader" nodes. The reader nodes are children to the Controller nodes. So fully expanded, my control should look somethign like this:

++ Root Node
    -- Controller Node
        -- Reader Node
        -- Reader Node
    -- Controller Node

This Treeview control is built entirely from the page's code-behind.  I have several context menus based on the type of node. The problem is that when I right-click, the context menu wil only display on the "root node". I cannot get a context menu to display on any other node.

I have alternately set the EnableContextMenu on the nodes without any effect. I have included a simplified version of the source code that creates the nodes.

So, any help would be greatly appreciated. Here's the code:

    
                        try 
        
                        {  
        
                            tvStatus.Nodes.Clear();  
        
                            RadTreeNode Root = new RadTreeNode(Resources.Globals.MenuCommandStatus);  
        
                            Root.EnableContextMenu = false; // I DON'T want a context menu on the root node  
        
                                            // controller menu  
        
                            RadTreeViewContextMenu mnuController = new RadTreeViewContextMenu();  
        
                            mnuController.ID = "mnuController" + DateTime.UtcNow.ToString();  
        
                            mnuController.SkinID = "WebBlue";  
        
                            RadMenuItem miControllerInit = new RadMenuItem(Resources.Globals.MenuInitialize);  
        
                            miControllerInit.SkinID = "WebBlue";  
        
                            RadMenuItem miSyncController = new RadMenuItem(Resources.Globals.MenuSyncControllerTimeMsg);

show filter and delete icons on grid

Hi,
When I look at the live demos solution that comes with the Telerik Rad Grid, there are icons for delete, filter, refresh, sort, and add column. However when I create my grid I can see the filter icons in design mode, but they are not there in runtime.

How can I get these icons to display without having to add an icon for each individual column as this is not done in the demo

Regards

Robert

How Do I ... SetFocus to a control w/i a Web User Control from C# Code-Behind

Ah, this used to be sooooooooooo easy ... place a RadAjaxManager in the control then use the SetFocus() method to move the focus around the web user controls as needed.

Now that only one RadAjaxManager can exist per .aspx page, this has become rather a nightmare. For me at least. And I've searched and searched and none of the solutions mentioned have worked for me.

I'm hopeful though. :)

Scenario: I've a default.aspx page. Kinda like a master page I suppose, but it is not a "Master Page". When I call this default.aspx page, I pass in a menuId value via the query string. Based on that menuId value, I load a particular web user control ascx into a placeholder on that .aspx. The .aspx page contains the RadScriptManager and the RadAjaxManager.
Constraint: I have to be able to set the focus at will via the C# code behind, from within any given loaded web user control, after any page load, post back, or ajax request. (Oh and please do not refer me to client-side examples; I've seen some here, and just can't manage to do the translation from client-side to code-behind from w/i a web user control; I need a translator :0) )
Would Like: a reusable solution as I do not want to have to recreate a chunk of code or javascript on each user control in general principle not to mention (though I am mentioning it aren't I?) to accomplish what used to be an oh so very simple one-liner.

Thanks in advance for any suggestions!

[Solved] TreeView Context menu

Hi,

I have this client side code, and I cant figure out, how can i close menu item from treeview, when I process it on client.

    
            <script type="text/javascript"> 
        
                function conetxtMenuClicked(sender, args) { 
        
                    var menuItem = args.get_menuItem(); 
        
                    var treeNode = args.get_node(); 
        
                    //alert(treeNode.get_value() + menuItem.get_text()); 
        
                    if (menuItem.get_value() == 'SetKeyWords') { 
        
                        menuItem.close();     
        
                        args.set_cancel(true); 
        
                        var window = radopen('/app/Pages/Admin/EditKeyWords.aspx?mpage=empty&nodeId=' + treeNode.get_value(), 'WVGA') 
        
                        window.setSize(800, 200); 
        
                    } 
        
                } 
        
            </script>

And this header of TreeView

    
            <telerik:RadTreeView ID="MainTree" runat="server" EnableViewState="false" OnClientContextMenuItemClicking="conetxtMenuClicked" OnContextMenuItemClick="MainTree_ContextMenuItemClick">

I need sometimes open radWindow and sometimes do regular postback. Problem is, when i open radWindow menu is still open.

Any ideas? Thanks!!!

Cannot get data from table within radpanel

Hi,
I am not having much luck getting input data from a table that is dynamically created within a radpanel and am hoping someone could tell me what I am doing wrong.

    
             <! -- Index data -----------> 
        
                       <telerik:RadPanelBar runat="server" ID="RadPanelBar1"

                                <telerik:RadPanelItem Expanded="True" Text="Index Information"  Selected="true">

                                    // Create column 1    
        
                                    TableCell td1 = new TableCell();  
        
                                    // Create a label control dynamically    
        
                                    Label _label = new Label();

                                    // Add control to the table cell    
        
                                    td1.Controls.Add(_label);  
        
                                    // Create column 2    
        
                                    TableCell td2 = new TableCell();  

                                    td2.Visible = true;
        
                                 }  
        
                                 // Add cell to the row  tr.Cel  
        
                                 tr.Cells.Add(td1);  
        
                                 tr.Cells.Add(td2);  
        
                                 // Add row to the table.   
        
                                 IndexTable.Rows.Add(tr);  
        
                            }

The table is displayed just fine but I can't retrieve any of the data that I input into cell 2. I have a "Submit" button that calls javascript to get the data but all I get is the label data, cell 1.

    
             <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">  
        
                  <script type="text/javascript">  
        
                      function GetIndexData() {  
        
                          var test = "";  
        
                          var tblIndex = $get('<%= ((Table)RadPanelBar1.FindItemByValue("IndexInformation").FindControl("IndexTable")).ClientID %>');  
        
                          var RowsLength = tblIndex.rows.length;  
        
                          for (var i = 0; i < RowsLength; i++) {  
        
                              var oCells = tblIndex.rows.item(i).cells;  
        
                              var CellsLength = oCells.length;  
        
                              for (var j = 0; j < CellsLength; j++) {  
        
                                  alert(oCells.item(j).innerHTML);  
        
                              }  
        
                          }  
        
                      }  
        
                  </script> 
        
                </telerik:RadCodeBlock>

I know I must be doing something wrong but I don't know what. Can anyone help me?

Thanks

RadWindow does not display inner text

    
                <telerik:RadWindow ID="winError" runat="server" Skin="Sunset"   
        
                    VisibleOnPageLoad="True" Behaviors="Close" Visible="False" Behavior="Close"   
        
                    VisibleStatusbar="False" VisibleTitlebar="False">  
        
                    <ContentTemplate> 
        
                        <asp:Label ID="lblErrorMessage" runat="server" /> 
        
                    </ContentTemplate> 
        
                </telerik:RadWindow>

I'm using the code and on server side whenever I got an error I populate lblErrorMessage text and make window visible. I always have an empty window popup also my intellisence tells me that: "Element 'contenttemplate' is not supported". What I'm doing wrong?

Thank you,
Roman.

Dock Style

Hi,

Is it possible to apply different skins for different docks without specifying the dock id in the style sheet(like #Raddock1 or so).
I need to just create a custom skin and apply the corresponding style to the dock with skin id.

Thanks in Advance
Pushpa.
