RadGrid ItemCommand event not firing after rebind

[Sebastien]

Hi,
Here is the scenario, 1 have 2 RadGrid on a web page. The first one is linked to a SQLDataSource and nothing on the interface can change the query so i dont have to call Rebind() method. But the second one has a filter combobox control that enable the user to filter the data. So i have a query with some parameters and once the query has changed, i have to call Rebind.

Here's the problem. Both Radgrid has a GridbuttonColumn. When i clicked on the first Grid buttonColumn the event ItemCommand is raised and i can do my stuff. But if i do the same with second grid, ItemCommand event is not fired because of that Rebind method. If i comment my 'RadGrid1.Rebind()' line and test it again ( So i play with the first snapshot of my data ), then the event is fired correctly.

Do i have to do something else after the Rebind method to make the ItemCommand event work properly ?

Thanks for your help !

Hello Sebastien,

Where are you calling the Rebind() method, in the ItemCommand? I don't understand what you're trying to achieve.

Hi Cori,
well, i tried a lot of stuff but basically i call the Rebind method in the SelectedIndexChanged of a combo box. This combo box contains some record status so i want to filter the grid depending on what the user has selected. So when i call the rebind method, the RadGrid NeedDataSource event is called so i can do my stuff to rebuild a datatable that i can give as my RadGrid DataSource. All that part works perfectly. But after that when i click on the RadGrid GridbuttonColumn , the ItemCommand is not fired anymore because of that Rebind method that i called earlier.
Again, if i remove my rebind code line, the ItemCommand is fired properly. But you understand that if i do that i cant filter anymore my grid so i need to call the rebind method.

I hope its more clear

Thanks

Hi Sebastien,

Could you paste your aspx and code-behind? Please, use the CODE-FORMATTER tool of the ticket editor for that purpose. No problem can be ascertained or even suspected from the description you have given.

Thanks.

I found this answer to work  http://www.telerik.com/community/forums/aspnet/grid/urgent-calling-rebind-doesn-t-call-the-needdatasource.aspx 

Basically set the datasource to null before the rebind call. Seems more like a bug to me.

Hello Sebastien,

I don't see how the indicated forum post is related to the issue you have stumbled upon. Please, give more details. Other than that, I'd really appreciated sending your files - I suspect the problem might be in the way you are data-binding/rebindnig the grid at some point in the page life cycle but where exactly is difficult to say without inspecting your implementation.

Thanks in advance.
