How to Change color in dataGridView cell..

If you  want to change the ForeColor and back ground color in the cell when the text is not in the correct format, I have this code to change the color after the text is entered

private void dataGridView1_DataError(object sender, DataGridViewDataErrorEventArgs e)
{
     dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.ForeColor = Color.Red;

dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColor= Color.Red;

}

hope this will solve your problem...
