Page Break When Printing

Topic Overview

Purpose

This topic provides a conceptual overview of the WinGrid™ printing feature that inserts a page break prior to each row meeting your specification criteria.

Prerequisites

To complete the procedure, you need to understand the following topics if you are not familiar with using the WinGrid with document printing concepts.

Overview

WinGrid page break overview

The WinGrid control’s printing functionality now supports a page break option enabling page breaks on specified rows or grouped rows in print preview and print.

This enhancement does not modify the existing behavior if there are no rows set to start a new page.

Note	Note This feature has no effect when the grid is in CardView. The printing behavior and records in card view of the WinGrid print normally.

Page break on specified rows

This requires using an UltraGrid print preview or print configured project. If this is not the case refer to the Prerequisites section before you continue.

Specify the row as the start of a new page by configuring the UltraGridRow object’s StartsNewPrintedPage property superseding the ViewStyleBand settings.

For example, setting the ViewStyleBand to Horizontal with the StartsNewPrintedPage set on a child row, that child row begins with the new page. If that child row is the first visible child, then the parent row will also be on the new page. The complete code for this scenario appears at the end of this topic.

Page break on grouped rows

Page break on grouped rows would be more useful or perhaps more common in an application where groups of rows can be printed on separate pages. This would require handling the InitializeGroupByRow event and initiate the page break on grouped rows.

In Visual Basic:

Private Sub UltraGrid1InitializeGroupByRow(sender As Object, e As InitializeGroupByRowEventArgs)
      ' If the grouped row has no parent then this is the first level of grouping.
      ' Now we want to start a new page with this group.
      If e.Row.ParentRow Is Nothing Then
            e.Row.StartsNewPrintedPage = True
            e.Row.ExpandAll()
      End If
End Sub

In C#:

private void UltraGrid1InitializeGroupByRow(object sender, InitializeGroupByRowEventArgs e)
{
    // If the grouped row has no parent then this is the first level of grouping.
    // Now we want to start a new page with this group.
    if (e.Row.ParentRow == null)
    {
        e.Row.StartsNewPrintedPage = true;
        e.Row.ExpandAll();
    }
}

Sample Data

Code Example: Creating a New Project

Description

Create a new project and add the following controls and components in your form:

UltraWinGrid
UltraPrintPreviewDialog
UltraGridPrintDocument
UltraButton (or Microsoft Button)

Code

Add the following namespace in your form:

In C#:

using Infragistics.Win.UltraWinGrid;

In Visual Basic:

Imports Infragistics.Win.UltraWinGrid

Code Example: Initializing the Grid

Description

The following is the code for implementing Page break on specified rows demonstrating the Initial WinGrid property settings in the form’s load event.

Code

In Visual Basic:

Private Sub Form1Load(sender As Object, e As EventArgs)
      ultraGrid1.DataSource = New MovieDataModel().MovieCategories
      ultraGrid1.DisplayLayout.ViewStyleBand = ViewStyleBand.Horizontal
      ' Set the UltraGridPrintDocument's Grid property to the Grid to print
      ultraGridPrintDocument1.Grid = ultraGrid1
      ' Set the UltraPrintPreviewDialog's Document property to the UltraGridPrintDocument
      ultraPrintPreviewDialog1.Document = ultraGridPrintDocument1
      ' Expand all rows for printing
      ultraGrid1.Rows.ExpandAll(True)
End Sub

In C#:

private void Form1Load(object sender, EventArgs e)
{
    ultraGrid1.DataSource = new MovieDataModel().MovieCategories;
    ultraGrid1.DisplayLayout.ViewStyleBand = ViewStyleBand.Horizontal;
    // Set the UltraGridPrintDocument's Grid property to the Grid to print
    ultraGridPrintDocument1.Grid = ultraGrid1;
    // Set the UltraPrintPreviewDialog's Document property to the UltraGridPrintDocument
    ultraPrintPreviewDialog1.Document = ultraGridPrintDocument1;
    // Expand all rows for printing
    ultraGrid1.Rows.ExpandAll(true);
}

Code Example: Setting up a Page Break

Description

The following code demonstrates how to insert a page break for each occurrence where the child row is a “PG” rated movie; configured in the grid’s InitializeRow event.

Note	Note Since all rows raise the InitializeRow event use `IsPrintLayout` to determine if the row is a print row thereby avoiding unnecessary property settings.

Code

In Visual Basic:

Private Sub UltraGrid1InitializeRow(sender As Object, e As InitializeRowEventArgs)
      Dim column As UltraGridColumn = ultraGrid1.DisplayLayout.Bands(1).Columns(2)
      Dim cellText As String = e.Row.GetCellText(column)
      ' The InitializeRow event is raised for on-screen rows as well, therefore
      ' we need to make sure the row is a print row with the following condition.
      If e.Row.Band.Layout.IsPrintLayout Then
            If cellText = "PG" Then
                  e.Row.StartsNewPrintedPage = True
            End If
      End If
End Sub

In C#:

private void UltraGrid1InitializeRow(object sender, InitializeRowEventArgs e)
{
    UltraGridColumn column = ultraGrid1.DisplayLayout.Bands[1].Columns[2];
    string cellText = e.Row.GetCellText(column);
    // The InitializeRow event is raised for on-screen rows as well, therefore
    // we need to make sure the row is a print row with the following condition.
    if (e.Row.Band.Layout.IsPrintLayout)
    {
        if (cellText == "PG")
            e.Row.StartsNewPrintedPage = true;
    }
}

Code Example: Print Preview

Description

The following code demonstrates how to display the print preview dialog window to inspect the pages prior to printing.

Code

In Visual Basic

Private Sub BtnPrintPreviewClick(sender As Object, e As EventArgs)
      ultraPrintPreviewDialog1.ShowDialog(Me)
End Sub

In C#:

private void BtnPrintPreviewClick(object sender, EventArgs e)
{
    ultraPrintPreviewDialog1.ShowDialog(this);
}
