I am trying to handle the double click event on a cell in a bound data grid. I'm doing this using the following as directed in other forum posts. grd.Model.Options.ActivateCurrentCellBehavior = GridCellActivateAction.DblClickOnCell; grd.DoubleClick += new System.EventHandler(MyHandler); grd.CellDoubleClick += new Syncfusion.Windows.Forms.Grid.GridCellClickEventHandler(MyHandler); My problem occurs due to MyHandler opening a dialog form which on closing returns focus to the original form on which the grid resides. When, on this original form, I click on another cell in the grid, the double click event is fired. How can I prevent this happening ? Also, I'd like to be able to have access to the contents of the cell, say to highlight and copy some text. With the code above controlling the current cell behaviour I can only achieve this after a double click, which in this instance fires the double click event and takes me through the handling routine. Any thoughts as to how I might achieve this functionality whilst retaining my double click handling ? Essentially I'd like to be able highlight the cell details as though the ActivateCurrentCellBehavior value were not set to GridCellActivateAction.DblClickOnCell whilst being able to capture a double click within the cell. Is this possible ? Many thanks, Rob Hughes

Here is one way I think you can display a dialog on a double click and then have an active cell afterwards (without getting a Double event when you click the next cell) is to: 1) this.gridControl1.Model.Options.ActivateCurrentCellBehavior = GridCellActivateAction.None; 2) Move your dialog from CellDoubleClick to DoubleClick, and begin edit on the currentcell afterwards.
private void gridControl1_DoubleClick(object sender, System.EventArgs e)
{
	MessageBox.Show("gridControl1_DoubleClick");
	this.gridControl1.CurrentCell.BeginEdit(true);
}
Default grid behavior lets you activate a cell for editing by pressing F2, so you can have an editing cell without double-clicking. But this may not be intuitive enough for your user. If you allow a single click to activate a cell, then it is tough to catch a double click. You can mark the time in of the single-click, and then if the embedded control gets another click within the DoubleClick time, then you could call it a double click, and perform your double click functions. This would take some work, but I expect it is doable.
