Hello Anton,

Can you please try using the code below instead of the masterTableView's rebind?

var grid = $find("<%= personsGrid.ClientID %>")
grid._clientSideBinding._change();
//grid.get_masterTableView().rebind();

Hi Peter!

Thank you, this seems to fix the issue on initial load. However, we still see the old behavior:

Using the original project, add a button that calls a function that "rebind" the grid
It does call the method multiple times again.

On initial load there is no problem, only upon rebinding.

We greatly appreciate the assistance. We will keeping an eye out for any new updates.

Thank you!

Hello all,

The issue seems to be fixed but the item was not updated properly. Attached you can find a sample project demonstrating the correct behavior.

In some cases, there might be an additional initial request when the pagesize of the ClientDataSource is not set and the PageSize of the Grid is different from the default PageSize=10.

Usually, this is fixed by setting the same PageSize to both Grid and ClientDataSource.

If anyone still experiences duplicate requests, please modify the attached project and send it back to us for further investigation.

Is this going to be fixed? We still encounter this problem.

Is this ever expected to be scheduled for a fix?  The problem seems to occur not only when navigating with a grid pager but by simply setting AllowPaging="true"
