Events and Customization

Updated over 6 months ago

RadPivotGrid exposes two events which you can use to format the appearance and add custom painting to your printed cells: the PrintElementFormatting and the PrintElementPaint events. The following sample demonstrates how you can mark in red the cells with value that is less than 100 and in green the cells with value greater than 500. Additionally, the cells that do not contain any value are grayed out with a hatch brush.

Formatting Print Cells

C#

private void radPivotGrid1_PrintElementFormatting(object sender, Telerik.WinControls.UI.PrintElementEventArgs e)
{
    PivotCellPrintElement cell = e.PrintElement as PivotCellPrintElement;
    if (cell != null && cell.Value != null && (Convert.ToDouble(cell.Value)) < 100)
    {
        cell.BackColor = Color.Red;
    }
    if (cell != null && cell.Value != null && (Convert.ToDouble(cell.Value)) > 500)
    {
        cell.BackColor = Color.Green;
    }
}
private void radPivotGrid1_PrintElementPaint(object sender, PrintElementPaintEventArgs e)
{
    PivotCellPrintElement cell = e.PrintElement as PivotCellPrintElement;
    if (cell != null && cell.Value == null)
    {
        Brush b = new HatchBrush(HatchStyle.BackwardDiagonal, Color.LightGray, Color.Transparent);
        e.Graphics.FillRectangle(b, e.Bounds);
    }
}

VB.NET

Private Sub radPivotGrid1_PrintElementFormatting(sender As Object, e As Telerik.WinControls.UI.PrintElementEventArgs)
    Dim cell As PivotCellPrintElement = TryCast(e.PrintElement, PivotCellPrintElement)
    If cell IsNot Nothing AndAlso cell.Value IsNot Nothing AndAlso (Convert.ToDouble(cell.Value)) < 100 Then
        cell.BackColor = Color.Red
    End If
    If cell IsNot Nothing AndAlso cell.Value IsNot Nothing AndAlso (Convert.ToDouble(cell.Value)) > 500 Then
        cell.BackColor = Color.Green
    End If
End Sub
Private Sub radPivotGrid1_PrintElementPaint(sender As Object, e As PrintElementPaintEventArgs)
    Dim cell As PivotCellPrintElement = TryCast(e.PrintElement, PivotCellPrintElement)
    If cell IsNot Nothing AndAlso cell.Value Is Nothing Then
        Dim b As Brush = New HatchBrush(HatchStyle.BackwardDiagonal, Color.LightGray, Color.Transparent)
        e.Graphics.FillRectangle(b, e.Bounds)
    End If
End Sub
