Paging on rad control

[lalit]

I am using a radgrid control where i have paging and autogenerate columns set to true. When i select a page on the radgrid it shows a panel id on the top and if i select again it works fine. It means it shows the panel id on every alternative select of a page in the grid. Can you help me to reslove it please?

[lalit]

This message comes on top when i select any page from the paging.

19676|updatePanel|ctl00_DefaultContent_ctl00_DefaultContent_pnlResultsPanel|

But if i select another page it goes away. It happenes alternatively, on page load it doesn't come , select any page this message comes and select again another page it goes away.

It looks like it is due to ajaxmanager's javascript but i don' know how to fix this.

Any one any idea.??

Hi Lalit,

The reason for this message most probably is wrong html sent in the response. However to investigate the problem further, we will need to replicate the issue locally. Can you strip the problematic page and post here the code we can use to observe the behavior?

Best wishes,

Hi Lalit,

Can you try using the Format Code Block tool of the editor where you post your replied to send the code, as this way it is either unreadable nor possible to format with Visual Studio?

Hi Lalit,

I reviewed the code and what I observed is that you are using RadAjaxmanager, RadAjaxPanel and ASP:UpdatePanel to ajaxify the same page content. Such upproach is not recommended and having such nested ajax panels is most probably the reason for the error. Try removing them one by on and see which causes the problem. Start with removing the RadAjaxManager settings. If the error persists, remove the RadAjaxPanel as well.

Check it out and let me know how it goes.

Kind regards,
