I have a RadToolBar in the CommandItemTemplate of a RadGrid.  I would like to (client-side) disable a button upon row click.  On row click I loop through the tool bar's items and disable the button I want.  This works but only disables the button on the top of the grid.  The command items at the bottom of the grid are left alone.  How can I disable both the top and bottom button?

 

How can I hide the title bar of a radnotification window?

I've tried this way:

 

 

But all my settings are ignored. Title is still visible. Close button either. 

I show it on postback:

 

 

Good day,

lately i have been battling with adding a label control inside a child tab so that i could display the challengers on after clicking on that tab

here is my code below...

 

I would like to add labels inside a child tab please help anyone,

please below capture

 

1/. My DataBase SquetchUp , and Request:

I have those 2 table :

In order to diplay in a cross table  I do this request:

2/. Telerik MarkUp 
My `RadPivotGrid` declaration:

3/. Current Result:

Current Result.
The expected result are the same but with out the (Blank) Row
**How do i achieve this ?**

When i click the button or try to post content In responsive view (mobile device views) We got "Invalid JSON primitive" error.

I have a grid with a single hierarchical child grid that the user may expand. I have the load mode set to "Client" and the edit mode set to "InPlace".

I want there to always be an insert row for the user to add new rows with if they wish. I have accomplished this with the master grid view (parent grid) with this function:

 

This will cause there to always be an insert row.

However, with the child grid in client mode, there is no callback between expand and collapse for the child grids.

I've tried this with no success:

 

What am I supposed to do here?

Hello

I have a complex grid with a GridButtonColumn where I want to set some parameters in codebehind. I'm using RadGrid1_PreRender for this.

Strangely, it only works after I used the pager to change page and not on first load... 

What am I missing here? I also Page_Load, Page_PreRender, OnColumnCreated, still it just never works on first load and it's driving me insane :/

Thanks!!

Hi,

Can anybody help me to solve this issue?

I am using RadComboBox and have an issue about this control. I am creating RadComboBox on server side and keep this control as Html like in .png. Everthing works fine on this situation. But when I try to update items for adding or removing any item, rcbSlide in body not updated, thats why combox does not display updated items. How can sync both rcbSlide in body and radcombox div? I tried copy html from div to body but, it does not work. Also when I close and reopen project new items displayed in combo. It seems body cache the items but I can not find have can I refresh items?

Please look at attached screenshots, 

CreateRadComboBox.PNG for creating html for RadComboBox
