Hi,

1. In our application we are using radGrid control with 8 combobox ,many textbox controls and hiddens fileds inside it. Based on the selection we show/hide combobox on grid.When edit button is pressed, we are filing and showing up comboboxes - When rows > 15 grid takes on average 20sec to come to edit mode.If rows are less still it takes 5-10sec. 

2. Based on button click we are adding the new row to radgrid from server side code, when again if rows >5 take 5-15 sec to a load.

3. On IE10(In one of the compatible mode) radCombobox width increases to the inner width of page.

4. RadWindow do not work on IE10(non -compatible mode), on button click we shows radwindow. Which workes properly on IE7/8/9

As of today many customers are using IE7/IE8.
Basically what I see is Telerik controls especially radGrid takes more time to render on IE-Browser.
If I run my page on Crome or Firefox, performance is very fast compared to IE7/8/9/10.
We tried the performance optimization suggested on your website, but still perofomance is very slow.

We are using Version : 2012.2.724.40.

If you have any suggestions, please reply.

Hi Shinu,

Thanks for your reply.

I have already added /removed many features from radGrid to increase its performance.
What I see is my server side code hardly takes .010 sec to process, but loading takes lot of time on browser to load. Which is making it very horrible to use on IE browsers compared to other.
