Hi Rekha,

Can you please also provide the code to populate the grid with data, as well as the code, which is used to actually delete a record?

Kind regards,

One of my collegue is also facing problem in pager refreshing:

http://cid-a38ba1c013b5d908.skydrive.live.com/self.aspx/ForForum/screen%20snaps%20for%20pager%20problem.JPG

Above link is the snapshot of following problem description.
Page is having 5 option button where we are displaying the radgid ibt the radajaxpannel on clicking on the SHOW button. Here at firt time the pageer in footer of the RadGrid show appropriate values but if we change the option button on the top to fetch the next report and when clicking on the SHOW buttton the data and the internal count on the table for row come ok, but the Previous result of the paging is displayed on the Radgrid.

This above Problem observed  when the records of the search is higher than the previous less record the higher figure remain in the Paging though the next display result is having the less count of rows. Also if the next result is carring higher rows count then it will get display in the paging.
Note:
1. in some option result we are hiding and displaying the columns by visiable property.
2. Is this the problem due to the Pannel is not full portback or any thing else.
3. Also internally we are using static datatable but the dat in the table comes on though we are passing the Rows count to a custom usercontrol on top of the grid to display.

Hello Rekha,

I reviewed the code, and it looks correct.
At this point, if the issue persists, please open a formal support ticket, where you can attach files, and send us a small working project, which demonstrates your logic, as well as the unwanted behavior.
I will debug it locally, and get back to you with additional information.

Sincerely yours,
Yavor

Hello Ivor

I have a similar problem to Rekha's where the paging of a RadGrid is not refreshing. If, for example, the first search returns 15 records and the second search 5 records, I see '... page 1 of 2...' in the second search which is incorrect info caused by the paging section of the grid not refreshing.

Please help as soon as possible. Thank you!

Hi Yosief,

Can you confirm that the delete procedure finished properly in your case?
Also, are you using custom paging? Any additional information on your setup might help us to find the source of the problem in your case.
