Here is my issue,

I have 15 columns radgrid. I didn't set any width property to my grid.
I can able to view all 15 columns in the grid using the browser's horizontal scroll bar.
Using the HeaderContextMenu i had hidden last 10 columns in the grid.
Then i made a sort in a column which causes a postback.
Now, there is no horizontal scroll bar in my page and balance 5 columns in my grid were visible in single screen.
Then i made all the hidden columns back to visible using the HeaderContextMenu.
But, i can't able to see the columns that i made visible. I can't able to see the horizontal scroll bar either.
if i performed a postback using columnsort or columnfilter, i can see the columns along with the horizontal scroll bar.

I guess you can understand my problem. Pls help and accept my aplogies for bad English.

Not found telerik assambly

Hi,
I have been working on one project since last 2 months and we are using telerik and visual studio. Today morning when I made some changes to one of the files of my project and tried to rebuild it, it suddenly gave me tons of errors. They are all related to telerik. It doesn't recognise any telerik controls. I tried adding Telerik.Web.UI.dll file by doing right click on the project-->add references. But got no luck. Check the screenshot I attached for the errors I am getting.
Please help me out. I have to fix this immediately.

Thanks,

No InsertItem Template in Grid

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!
