Hi,

I've customized a RadGrid so that my Category field can be selected from a dropdownlist.

I've done this via the following code in the 'EditItem' template for my ProductCategoryName Template column
As shown below

<telerik:GridTemplateColumn DataField="ProductCategoryName"
            DefaultInsertValue="" HeaderText="Category"
            SortExpression="ProductCategoryName" UniqueName="ProductCategoryName">
            <EditItemTemplate>

           <asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SqlDataSourceCategories" DataTextField="CategoryName" DataValueField="CategoryName" SelectedValue='<%# Bind("ProductCategoryName") %>'>
           </asp:DropDownList>


            </EditItemTemplate>

My problem is that it appears that the RadGRid does not have an <InsertItemTemplate> and instead just uses whetever is in the
<EditItem> Template when one is in in Insert mode.

This, naturally means that I get the following error...

'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value

Would anyone be able to provide me with a solution for this problem ?

Dynamicaly adding "Asp:Checkboxlist" as RadTree inner node

Hi,

Apologises for my previous post - codesnippet formatting didn't work.

Well, I am looking for a solution where by I can have a Radtree with nodes. Each node will have inner node containing checkboxlist. All nodes and checkboxlist get populated from database. It can be done in designtime with NodeTemplate. I am sure it is possible in runtime as well but I am not sure how can I add NodeTemplate in runtime to the inner nodes only. I looked into documentation NodeTemplate in Runtime but doesn't help a lot.

Could you please kindly hint me how it can be achieved.

Thanks in advance.

Cheers,
M G

[Solved] jquery $find doesn't return checkbox

I'm not sure if this is related just to jQuery, or if there is an issue with the Telerik version thereof.

    
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" /> 
        
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />

My goal is to capture the Enter key in a textbox, and depending on the textbox which has focus, move to the next appropriate control. When I move from one textbox to another, it's fine. When I want to move from a textbox to a checkbox, I can't get an object for the checkbox, the return value (ctrl) is null. The following is in a RadCodeBlock.

    
            function KeyPressed(ctrl, e) {  
        
              if (e.get_domEvent().rawEvent.keyCode == 13) {  
        
                var ID = ctrl.get_id();  
        
                var ctrl;  
        
                if (ID.indexOf("F1") >= 0) ctrl = $find("<%= F2.ClientID %>");      
        
                if (ID.indexOf("F2") >= 0) ctrl = $("#<%= C1.ClientID %>"); // fail       
        
                // $find("<%= C1.ClientID %>"); // this didn't work either  
        
                if (ctrl !== null) {      
        
                  e.set_cancel(true);      
        
                  setTimeout(function() { ctrl.focus(); }, 1);      
        
                }  
        
                ...  
        
              }  
        
            }

The F1 and F2 controls are textboxes. C1 is a checkbox (all control names simplified for this text). The controls look like this:

    
            <telerik:RadNumericTextBox ID="F1" Width="80px" runat="server" 
        
              Type="Number" NumberFormat-DecimalDigits="0" ClientEvents-OnKeyPress="KeyPressed" /> 
        
            ...  
        
            <telerik:RadNumericTextBox ID="F2" Width="80px" runat="server" 
        
              Type="Number" NumberFormat-DecimalDigits="0" ClientEvents-OnKeyPress="KeyPressed" /> 
        
            ...  
        
            <asp:CheckBox ID="C1" runat="server" Text="Check Me!" />

I'd like to understand what's wrong, but since we're here, outside of this kind of manual wiring, is there any more elegant way to set the Enter key to follow TabStops?

Thanks!

[Solved] Collapse right to left

I've looked at the demos and did not see one that shows this - so, is it possible to have a dock that collapses from right to left?
Im trying to create something that would have two panels, side by side. The left one (Panel1) would be an informational panel that the user could pin or collapse and when collapsed the other panel (Panel2) would fill the browser window.

[Solved] ToString() called for object while databinding

It seems that ToString() is called for every object in datasource with no reason. My problem is that the function is overrided and is time consuming (bad writed).

After some research, i see the line in GridBoundColumn.cs in method OnDataBindColumn
if (item1.DataItem != null && item1.DataItem.ToString() == "Microsoft.SharePoint.WebControls.SPDataSourceViewResultItem")

I do not known why it is necessary, why not item1.GetType().FullName ?
