Hi, I have a radStripTab with 3 tabs, each tab has a radgrid. When I change a register status (have a column button to do this) on the first radgrid the register should disappear from the first radgrid and should be shown on the second radgrid -that is on the second tab-

In my NeedDataSource method I refresh the datasource for both of the radgrids, the problem is that only the first radgrid refreshes when I change tabs the second radgrid doesn't have the latest data.

This procress applies also for the second and third radgrids, and the issue happens, when I make a change on the second radgrid the change is shown but you wont se the updated data on the third one. So the rebind is only working on the radgrid where you make the change and I need it to refresh the three radgrids.

Any idea on what should I do? Thanks

    
            Protected Sub RadGrid_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource, RadGrid2.NeedDataSource, RadGrid3.NeedDataSource
 
                    Dim wsNC As New webService
 
                    RadGrid1.DataSource = wsNC.searchByStatus("0")
 
                    RadGrid2.DataSource = wsNC.searchByStatus("A")
 
                    RadGrid3.DataSource = wsNC.searchByStatus("R")
 
            End Sub

Hello adrian,

Is the setup ajaxified? If this is the case, improper ajax settings may be causing this behavior - you can temporarily disable ajax to verify this. In any case, calling RadGrid.Rebind() should refresh the content(s) of the control.
If the problem persists, you can open a formal support ticket, and send us a small working project, demonstrating your setup, and showing the unwanted behavior, for additional review and testing.

I'm having a very similar problem.

I've got a page layout using raddocks, with a slider control in one dock and a grid in the second dock.

I use a dock custom command to save the value of the slider which in turn enters the relevant number of rows into a table. The grid is then rebound and even thought the datatable I'm binding to in the rebind event is returning the extra rows the grid is not displaying them.

I have dock zone 1 updating the grid in dock zone 2 using the ajax manager...and the loading panel is displaying for the the grid.

I'm using the 2010.1.519 build.

Regards
Cliff

Hello,

Could you please elaborate a bit more on your application? Does the scenario works as expected if the Ajax is disabled on the page? If it is convenient for you please open a regular support ticket and send us runnable application which demonstrates the issue. We will test it locally and advise you further.

Sincerely yours,
