In Windows application with C#.net :

when keypress event firing on flexgrid but not return value.when use dobleclick event return value.

What I have tried:

Grid_KeyPress

int row = GrdDc.Row;
if (GrdDc.ColSel == 1)
{
if (e.KeyChar != (int)Keys.Escape && e.KeyChar != (int)Keys.Enter && e.KeyChar != (int)Keys.Tab)
{
if (Convert.ToString(GrdDc[row, 10]) != "1")
{
Callsearch("Component");
SWOT_MFG.FrmView FrmV = new SWOT_MFG.FrmView(this, "DisAssemble");
FrmV.ShowDialog(this);
e.Handled = true;
}
}
}
