Hi

I'm using UltraGrid v7.3, and implemented following logic.

1. single click on cell will select the whole row. 
code:         
void ultraGrid1_InitializeLayout(object sender, InitializeLayoutEventArgs e)
 {
            e.Layout.Override.CellClickAction = Infragistics.Win.UltraWinGrid.CellClickAction.RowSelect;
}

2. double click on cell edit the cells value.
void ultraGrid1_DoubleClickCell(object sender, DoubleClickCellEventArgs e)
{
      e.Cell.Activate();
      this.ultraGrid1.PerformAction(UltraGridAction.EnterEditMode);
}

It is all right with single click and double click. I can get what I want. However if I add a maskInput for a column in InitializeLayout method.  Then I double click on the cell of the column, it won't enter into edit mode again.  Why is this, how could I remain double click functionality with maskInput set.

Modified InitializeLayout method:
void ultraGrid1_InitializeLayout(object sender, InitializeLayoutEventArgs e)
{
    e.Layout.Override.CellClickAction = CellClickAction.RowSelect;

    UltraGridColumn column = e.Layout.Bands[0].Columns["qty"];
    column.MaskInput = "{double:-7.2}";
    column.MaskDataMode = Infragistics.Win.UltraWinMaskedEdit.MaskMode.Raw;
    column.MaskDisplayMode = Infragistics.Win.UltraWinMaskedEdit.MaskMode.IncludeLiterals;
    column.MaskClipMode = Infragistics.Win.UltraWinMaskedEdit.MaskMode.IncludeLiterals;
}
