Hello
I have radiobuttons in my webform. I also have a radgrid which is visible=false when I load the form. When I select a choice on the radiobutton, I want my radgrid become visible. This is working fine. But I lose all rows that I have in my radgrid. I can only see a light blue horizontal line. Nothing appear in the radgrid. When I don't put the radgrid.visible=false I see my rows in my grid...
Here is my code

Hi Myriam,
RadGrid fires the NeedDataSource event each time it needs to be bound to a data source. If, at the time of the event, the DataSource property is not set to a valid data source object, the grid will not behave correctly.
Please note that you should never call the Rebind() method in a NeedDataSource event handler.
For more information about advanced Data- binding, please refer to the following help article:
