Implementing Double Click event in Search Grid
Double click event is implemented in the Search Grid (or simple Grid) using activationAction event handler.
The activationAction sets the action to be launched when a cell in a row is double clicked. This action is executed if and only if the cell is not editable and the corresponding column control of the cell is not an action control (hyperlink or button).
See the Implementing Double Click event in Search Grid for a step by step example.
