Hello All.

I have the following problem. The following code is not working. Everything that I want is to add RadButton control to FooterTemplate of the Calendar in RadDatePicker.


As far as I know there should not be any problems with adding IScriptControl (web server controls with client side support) to template of any control (if this template is proper instantiated and created).

The error which I received:

Script control 'RadButton1' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentException: Script control 'RadButton1' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Thank you in advance.

Hi,
I have one data bound tree view. 
On three view click i Need to refresh my Grid..

On Treenode click event handler. I called the RadGrid's Rebind Method and it call the RadGrid1_NeedDataSource method where i again reset the Datasource of the grid according to selection in the treeview. But my grid is not updating the datasource..

Here is some code..


Node click handler 


DataSource is perfect but Not refreshing the grid.. But when manually refresh the grid from refresh button in grid. work awesome..
Please help me its very urgent..
Thanks.

Good morning.  I have 2 grids that use a RadWindow to do their Insert/Updates.  I have them returning and updating properly.  The only problem is that I noticed is that when I update one grid, both grids are refreshed by the ajax manager.  I'd like to see only one grid refresh at a time.

Below is the AJAX setting to allow the rebinds to happen.

Below is the call to refresh the grids based on type.  I'm mostly sending you this so that you can see the AJAX call.


Is there a way to only refresh one of these grids at a time?

Thanks!

Hi,
I want to allow sorting in my grid when there is data and disallow sorting when there is no data.
But i find out that once i disallow sorting in NeedDatasource event , it will forever disallow sorting . And i find out that my code in allow/disallow sorting in ItemDataBound event do not work at all.
Below is my code !!

Does anyone has any idea?
HELP Please!!

Hello all,

 

From the beginning I am  in a fight with FormDecorator.

He doesn’t do what I want him to do.

 

I have a simple example

A FormDecorator with 2 Telerik controls and a Windows Button.

 

 

 

On the normal Button it’s working but on the other controls it doesn't

 

I have followed some examples but everything is very straight forward so what I am missing here?

 

Best regards,

 

Marco

Hi,

Can somebody help me with showing and hiding tabs in code behind? I've tried many methods and none seem to work. I really appreciate your assistance with this one.

Thanks,
Ron.

Is there a way to ensure that the RadGrid control height is always 100% of the datasource content?

For example, if there are only 3 rows in the grid, the height of the grid control would only be as tall as the three rows in the datasource plus the header row.  All controls on the page below the grid would be displayed directly below the grid.

If the datasource of the grid changed so that the results contained 15 rows, the height of the grid would change to show all 15 rows, and again, any controls on the page below the grid would show directly below the results.

Thanks.

I find an issue in Radgrid.  I couldnt fix it.   I create some columns programmatically.  When I hide colum from header context menu, some blank colum is appear al last.  Copy aspx, aspx.cs and Image (before and after hide column)...  ASPX:                                            <%@ Page Title="" Language="C#" MasterPageFile="~/UI/Doculex.Master" AutoEventWireup="true" CodeBehind="DocumentsList.aspx.cs" Inherits="WebSearch.UI.DocumentsList" %>

i have a problem with the OnNodeClick event in the tree view. I have the following code in ascx file :


And i am adding the nodes in the code behind:

My code behind:

 
On Init i am just loading one root node guest, and when Expand is clicked, i am populating
1 to 10 as child nodes. Now, when i click on one of the nodes, i can hit the break point  at RadTreeView1_NodeClick and when i run, the tree is getting populated and
everything is fine. Now, my problem is, when i click another node, i CANT hit
the break point(on the second node click) and the tress is also not getting
populated. I can just see "Guest" and not the below nodes. Can any one
please help me. Thanks
