Hi,

My topic is not exactly right, because the column headers are colored, but .. I change the text color for cells which contain violations to red via row.Cells["sample_mean"].Appearance.ForeColor = Color.Red; But in the print previews and printnigs this is always black.. My print function looks like this:

 private System.Drawing.Printing.PrintDocument c_pdSetup = new System.Drawing.Printing.PrintDocument();

private void pshGridPrint_Click(object sender, EventArgs e)
{
            // display page setup dialog
                c_pdSetup.DefaultPageSettings.Landscape = true;
                c_pdSetup.DefaultPageSettings.Color = true;               
                pageSetupDialog1.Document = c_pdSetup;
                if (pageSetupDialog1.ShowDialog() == DialogResult.OK) this.SampleDataGrid.PrintPreview(this.SampleDataGrid.DisplayLayout, c_pdSetup);

}
