Item template columns not loading

[ratan mishra]

 

Hi there,

1) Iam using a Radgrid which consists of '5' image columns on page load it is getting loaded fine but when I perform any Filter option which is provided with grid it is taking time for getting loaded for image columns remaining columns load quickly same with page index also is not getting loaded it is getting loaded after any event is performed like button click i want to get the page updated quickly without any event firing.

2) And Iam facing another problem with grouping it is grouping properly when i drag some times it is grouped but some times not in this also image columns are not getting loaded when iam ungrouping it is throwing an exception.

3) I want Tooltip for Radgrid for all columns It should display according to database.

I need to do ASAP please any help would be appreciated

Hi ratan,

Based on the supplied information, it is hard to determine the cause of the problem. To do so, it will be best if you open a formal support ticket, and send us a small working project, demonstrating your setup, and showing the unwanted behavior(s). We will debug them locally, and get back to you with more information on the matter.

All the best,
Yavor
