How to create an EmptyDataText for a DataGridView in a Windows application

Today I ran into a problem to show / hide the label according to the data source. If the data source does not have a row, then I would like to set "No data" , otherwise display the number of records in the winforms application .

This is possible in Asp.net, for example:

<emptydatatemplate>
No Data Found
</emptydatatemplate>

OR

EmptyDataText=" No Data Found"

But I would like in a Windows Application. Please help me if you have a solution for this.

Any solution would be appreciated! Thanks, Imdadhusen

One way to achieve this is to use the Paint () event to check the lines, and if they are not there, write your message: Collapse

private void dataGridView1_Paint ( object sender, PaintEventArgs e )
{
    DataGridView sndr = ( DataGridView )sender;

    if ( sndr.Rows.Count == 0 ) // <-- if there are no rows in the DataGridView when it paints, then it will create your message
    {
        using ( Graphics grfx = e.Graphics )
        {
            // create a white rectangle so text will be easily readable
            grfx.FillRectangle ( Brushes.White, new Rectangle ( new Point (), new Size ( sndr.Width, 25 ) ) );
            // write text on top of the white rectangle just created
            grfx.DrawString ( "No data returned", new Font ( "Arial", 12 ), Brushes.Black, new PointF ( 3, 3 ) );
        }
    }
}
