The first thing I tried was setting Enable View State to true on the grid (I'd switched it off previously). When the row is in edit mode i display a checkbox and textbox.
At design time, you can find server-side events in the Events section of the property window once you add a behavior to Web Data Grid.
On the Row Data Bound event of the Parent Grid View I am first searching the Child Grid View in the corresponding Grid View Row and then populating it with the records from the Orders table of the Northwind Database based on Customer Id stored in the Data Key property.
The client-side and server-side events are separated into categories based on the behaviors they correspond to in Web Data Grid™.
Binding form controls is mostly a simple matter of attaching a Data Source and setting your controls to reference the correct field in the Data Source.
Binding a Grid View control can sometimes get tricky when using the Visual Studio editor, especially when working with Drop Down List controls within the grid.
Gridview row click event fires, when clicking on controls within row. Those events are not firing on the first click, but they are firing on th second click.
