IE7 slow with RadGrid

[srinivasan pn]

We have a data intensive application and in one particular page, we have a Rad Grid display 180 columns/10rows of data. The page works well in IE8 and takes about 10 seconds to load, but the same page takes one and a half minute to load in IE7.

We know that IE7 Javascript is slower than IE8, but the difference in rendering times between these two browsers is very high. Are there any suggestions to improve the performance in IE7?

Hi Srinivasan,

As you already mentioned the javascript engine of IE7 is slower than the one of IE8 browsers. There is no specific steps you could apply especially for IE7 control however applying the general optimization techniques should also improve the performance in this browser. See the following help topics which elaborates on this matter:

I hope this helps.
