SYMPTOMS
If a grid's Click or Dblclick method contains drill-down code that enables the user to move to (drill down to) detailed information, then as long as the mouse pointer (cursor) is over a filled cell, neither the Click nor Dblclick methods of the grid respond. Instead, the Click and Dblclick events select the text field and allow data editing in the field if the appropriate property is set to true.

The only way to get the grid's Click and Dblclick methods to respond is to place the pointer over a part of the grid that does not have records in it.



CAUSE
The Grid-level Click or Dblclick methods do not work when the pointer is over a non-empty cell of the grid. They are designed to work only if the pointer is over an empty cell.



RESOLUTION
To trap for a mouse click or double-click in a filled record cell, you should place the drill-down code in the Click or Double-Click event of the CurrentControl object of the Grid Column. For example, if Text1 is the CurrentControl for Column1 of Grid1, then place the Drill-Down code in Grid1.Column1.Text1.Click|DblClick event, not in the Grid1.Click|DblClick event. Events that occur over the cells are trapped by the object contained in the columns, which in this case is Text of the Grid.



STATUS
This behavior is by design.



MORE INFORMATION
A Drill-Down implementation allows you to display detailed information for a specific object. You may want to display detailed information, such as a list of all the fields, for a specific record in a grid by clicking or double-clicking with the mouse on one of its cells or fields.
