checkbox selection is very slow...

[Babu Puchakayala]

Hi,

I am using telerik radgrid. The radgrid performance is worst in following  scenarios. Please let me know if there is any other way to improve the performance.

1. I have radgrid with PagerStyle Mode="NextPrevAndNumeric" option, In dropdown i implemented "viewall" option to show all rows in a grid. When i selected view all option the radgrid performance is very slow in both  IE6, IE7 and Firefox. Even its getting stuck (See the attached image) in both browsers. I am showing around 6000 records in radgrid. Its taking around 30sec - 40sec to show the all rows in a grid and the grid is very slow for swapping, filtering, sorting and even for scrolling down.

2. I have GridClientSelectColumn in my radgrid. When I am showing all rows in a grid and when I am trying to select all rows in a grid using check box column its getting very slow in IE7(around 6 - 7 sec to select all rows) But in Firefox it is better( 2 sec).

Is there any better way to improve performance of a radgrid. Is there other way to bind the data to the grid when user select "viewall" option?

Please find my attached code.
