I'd like to have several grids on a web page, each inside a separate UpdatePanel in conditional update mode.

Then I'd like to be able to page or sort a single grid, and have only that grid populate its data from the database.

The other grids should not do a DataBind(). So, I want to know, for each UpdatePanel, whether it will be updated on the client.

It would seem that the IsInPartialRendering property could be used for this, but it always seems to return false, at least during the Load and PreRender events of the UpdatePanel.

In what way can this behavior be implemented? We really don't want to retrieve data that won't be sent back to the client.

during the Load and PreRender events of the UpdatePanel.

Am not sure are using the UpdatePanel Load and Prerender method to check IsAsyncPostback. Could you also post some code?

Hi

"So, I want to know, for each UpdatePanel, whether it will be updated on the client."What you mean?

Hi

You want that just one updatepanel be postbacked and be DataBinded in asynpostback,Then you want to get data from that updatepanel and refresh other updatepanel with these data on the client.

Is this what you want?

I think you can do this via javascript at the requestEnd event handler.

If you need more information,please let me know.

Thanks
