GridView.BeforePrintRow Event

Fires before printing/exporting each individual row, and allows you to add custom information to the printout/export output, and prevent a row from being printed/exported.

Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v18.2.dll

Declaration

C#

[DXCategory("Printing")]
public event BeforePrintRowEventHandler BeforePrintRow

VB.NET

<DXCategory("Printing")>
Public Event BeforePrintRow As BeforePrintRowEventHandler

Event Data

The BeforePrintRow event's data class is CancelPrintRowEventArgs. The following properties provide information specific to this event:

Property	Description
BrickGraphics	Gets a BrickGraphics object that implements report drawing functions. Inherited from PrintRowEventArgs.
Cancel	Gets or sets whether the current row must not be printed/exported.
Graphics	Gets a GDI+ grid’s drawing surface. Inherited from PrintRowEventArgs.
HasFooter	Gets whether the row contains a footer. Inherited from PrintRowEventArgs.
Level	Gets the group level of the printed row . Inherited from PrintRowEventArgs.
PS	Gets the PrintingSystem object that provides methods to create bricks in the printout/export output. Inherited from PrintRowEventArgs.
RowHandle	Gets the handle of the printed row. Inherited from PrintRowEventArgs.
X	Gets or sets the X coordinate, in pixels, where the next row will be drawn in the printout/export output. Inherited from PrintRowEventArgs.
Y	Gets or sets the Y coordinate, in pixels, where the next row will be drawn in the printout/export output. Inherited from PrintRowEventArgs.

Remarks

When printing and exporting data, the BeforePrintRow and GridView.AfterPrintRow events fire, and these allow you to perform printout/export output customizations.

Using the BeforePrintRow event is equivalent to the GridView.AfterPrintRow event. See this link, for more information, and an example.

Example

The following example shows how to add custom information to the printout/export output when the grid control is printed/exported.

In the example, the GridView.BeforePrintRow event is handled to add a custom footer after every 5 grid rows have been printed. After every 10 rows, a page break is inserted:

Note

To compile this example, ensure that the XtraPrinting library is added to the References section of your project.

C#

using DevExpress.XtraPrinting;

private void gridView1_BeforePrintRow(object sender, 
DevExpress.XtraGrid.Views.Printing.PrintRowEventArgs e) {
    // Insert a custom footer.
    if ((e.RowHandle + 1) % 5 == 0) {                
        // Create a text brick and customize its appearance settings.
        TextBrick tb = e.PS.CreateTextBrick() as TextBrick;
        tb.Text = "Custom footer";
        tb.Font = new Font(tb.Font, FontStyle.Bold);
        tb.HorzAlignment = DevExpress.Utils.HorzAlignment.Near;
        tb.Padding = new PaddingInfo(5, 0, 0, 0) ;
        tb.BackColor = Color.LightGray;
        tb.ForeColor = Color.Black; 
        // Get the client page width.
        SizeF clientPageSize = (e.BrickGraphics as BrickGraphics).ClientPageSize;
        float textBrickHeight = e.Graphics.MeasureString(tb.Text, tb.Font).Height + 4;
        // Calculate a rectangle for the brick and draw the brick.
        RectangleF textBrickRect = 
            new RectangleF(0, e.Y, (int)clientPageSize.Width, textBrickHeight);
        e.BrickGraphics.DrawBrick(tb, textBrickRect);
        // Adjust the current Y position to print the following row below the brick.
        e.Y += (int)textBrickHeight;
    }
    // Add a page break.
    if ((e.RowHandle + 1) % 10 == 0) {                
        e.PS.InsertPageBreak(e.Y);
    }
}

// Show a print preview
private void simpleButton1_Click(object sender, EventArgs e) {
    gridControl1.ShowPrintPreview();
}
