GridComboBoxRenderer double click

[Hans Dampf]

Hi,

we have a derived grid combo box cell (which is editable). Now when I make a double click in the cell I want the current value to be highlighted. The current behavior is that the value in the cell changes to the next value of the listbox. So how can I hightlight the cell value with a double click instead of switching to the next item of the listbox.

Cheers,
Al

PS: I have attached a sample where you can see the behavior

Hi Al,

You turn off selecting the next index when user double clicks inside the cell by setting the AllowDoubleClickChangeSelectedIndex property to false. Here is a code snippet

public class MyComboBoxCellModel : GridComboBoxCellModel
{
public MyComboBoxCellModel(GridModel grid): base(grid)
{ this.AllowDoubleClickChangeSelectedIndex = false;
}
public override GridCellRendererBase CreateRenderer(GridControlBase control)
{
return new MyComboBoxCellRenderer(control, this);
}
}

Sample: DropDownBox_Select.zip

Best regards,
