Hi Telerik team
please read the following scenario carefully.
I have a RadGrid with the following properties:

<EditFormSettings EditFormType="WebUserControl" UserControlName="../UCF/UCF_Blood.ascx">

  • The web user control contains another 3  (at least ) RadGrid(s).
  • Each RadGrid that have at least 20 columns per one.
  • These grids works as a child for the parent  grid.

When I’m trying to edit the parent row (parent grid) then the grid turns into edit mode diplaying the parent data plus the other child grids.

The problem is that: after data binding and form return to end user (browser) it takes several seconds to be able to interact with the grids.

I think that
Telerik take long time trying to adjust the interface of  RadGrids controls.

If you try to click any where in the Brower you well get the error

"a script in this page is causing internet explorer to run slowly ....".

When I minimized the number of displayed rows  in child RadGrid it works fine.

Of course I could not consider this as a solution.

Please provide me with the help.

Remarks:

  • This is done using RadControls for asp.net Ajax 2008-Q2.
  • The dot net framework version 3.5.
  • Also note that I'm using RadAjax loading panel for the parent grid.

Hi Moustafa,

Can you verify how many rows you have in the grid and what is the HTML size? Any more info will be appreciated.

Sincerely yours,

Dear all:

According to the number of rows
I have only 5-10 rows at most per grid.
you  also should take in your  consideration that I'm using paging with page size 10 row per page.

According to the size of the  html 
I think it is not large to make this troubles

Note: currently I'm trying to prepare online server for testing.

thanks for you
