Question

I am working on winform C# datagirdview and I would like to change the color of a particular row in my datagridview. The row should be changed to red when the value of columncell is false.

Answer 1

Use the CellFormatting Event

   private void dataGridView2_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
    {
        if (e.ColumnIndex == 1)
        {
            if (e.Value != null)
            {
                if ((bool)e.Value)
                    dataGridView2.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Blue;
                else
                    dataGridView2.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Red;
            }
        }
    }

EDIT:

The value of e.value is base on the e.ColumnIndex for more Details
