Help me Please..!!!
private void gvLoadAllData_DoubleClick(object sender, EventArgs e)

if()

//Do Something

Answer
DoubleClick on Row Header
To handle a double click on row header, handle RowHeaderMouseDoubleClick event of DataGridView:
private void dataGridView1_RowHeaderMouseDoubleClick(object sender,
DataGridViewCellMouseEventArgs e)
{
var rowIndex = e.RowIndex;
//You handled a double click on row header
//Do what you need
}
DoubleClick on Column Header
To handle a double click on column header handle ColumnHeaderMouseDoubleClick event of DataGridView:
private void dataGridView1_ColumnHeaderMouseDoubleClick(object sender,
DataGridViewCellMouseEventArgs e)
{
var columnIndex = e.ColumnIndex;
//You handled a double click on column header
//Do what you need
}
Using DoubleClick
Also if for any reason you want to use DoubleClick event, here is what you should write:
private void dataGridView1_DoubleClick(object sender, EventArgs e)
{
var g = sender as DataGridView;
if (g != null)
{
var p = g.PointToClient(MousePosition);
var hti = g.HitTest(p.X, p.Y);
if (hti.Type == DataGridViewHitTestType.ColumnHeader)
{
var columnIndex = hti.ColumnIndex;
//You handled a double click on column header
//Do what you need
}
else if (hti.Type == DataGridViewHitTestType.RowHeader)
{
var rowIndex = hti.RowIndex;
//You handled a double click on row header
//Do what you need
}
}
}
