Create Formatting Print Grid Cell in C#

To create formatting cell in grid, we need to use the event, FormatPrintCell, included in the GridView C# class. This event works in the same way of any other formatting events of Kettic GridView and allows the developers to format the appearance of the cells that will be printed. The following is the C# code that shows how to customize the appearance of the header and the summary rows.


private void ketticGridView1_FormatPrintCell(object sender, FormatPrintCellEventArgs e)
{
    if (e.Row is GridViewTableHeaderRowInformation)
    {
        e.PrintCell.DrawFill = true;
        e.PrintCell.BackColor = Color.SkyBlue;
        e.PrintCell.BorderColor = Color.Blue;
    }
    else if (e.Row is GridViewSummaryRowInformation)
    {
        e.PrintCell.DrawFill = true;
        e.PrintCell.BackColor = Color.LightSalmon;
        e.PrintCell.BorderColor = Color.Tomato;
    }
}

How to Paint Print Grid Cell in C#

To paint print grid cell in C#.NET template projects, we need to use the event, PaintPrintCell, included in the GridView C# class. This event allows the developers to access the grid cell and paint the cells as their needs. The following is the C# code that shows how to paint a blue dot if the product quantity is larger than 50 and a purple dot when it is smaller.


private void ketticGridView1_PaintPrintCell(object sender, PaintPrintCellEventArgs e)
{
    if (e.Row is GridViewDataRowInformation & e.Column.Name == "UnitsInStock")
    {
        int side = e.CellRect.Height - 10;
        int x = e.CellRect.X + 5;
        int y = e.CellRect.Y + 5;

        Rectangle rect = new Rectangle(x, y, side, side);
        Brush brush = default(Brush);

        if (Convert.ToInt32(e.Row.Cells[e.Column.Name].Value) < 50)
        {
            brush = Brushes.Purple;
        }
        else
        {
            brush = Brushes.Blue;
        }

        e.Graphics.FillEllipse(brush, rect);
    }
}
