AutoPreviewMaxLines Property

Returns or sets the maximum number of lines to be auto-previewed
Syntax
'Declaration
 
Public Property AutoPreviewMaxLines As Integer
public int AutoPreviewMaxLines {get; set;}
Remarks

The AutoPreview area appears under a row and provides a way to display multiple lines of text associated with that row. You can specify how many lines of text should be displayed, and choose to either display the value from a cell in the row or a custom text string that you specify. One common use might be to display the contents of a memo field that initially appears off-screen when the grid is loaded.

The AutoPreviewMaxLines property specifies the maximum number of lines of text that will appear in the AutoPreview area. The default value is 3.

The Description property of the row determines the text to be displayed in the AutoPreview area. Description can be automatically set using the field in the row specified by the AutoPreviewField property, or it can be explicitly set through code (for example, in the InitializeRow event handler).

Example
Following code shows how one can enable and customize the Row Auto Preview functionality.

Imports Infragistics.Win.UltraWinGrid

  Private Sub Button25_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button25.Click

      Dim band As UltraGridBand = Me.UltraGrid1.DisplayLayout.Bands(0)

      ' Set the AutoPreviewEnabled to enable row previews.
      band.AutoPreviewEnabled = True

      ' Set the AutoPrevieField to the field contents of which will be  displayed
      ' in the row preview.
      band.AutoPreviewField = "Address"

      ' Indent the text in row previews by 5 pixels
      band.AutoPreviewIndentation = 5

      ' Allow the row previews to display up to 4 lines of text if the text is 
      ' multiline.
      band.AutoPreviewMaxLines = 4

      ' Change how the row preview will look by setting RowPreviewAppearance 
      ' off the override.
      band.Override.RowPreviewAppearance.BackColor = Color.DarkBlue
      band.Override.RowPreviewAppearance.ForeColor = Color.LightYellow

      ' You can set the row preview appearance on per row basis overriding the
      ' settings on the Override.RowPreviewAppearance.
      Me.UltraGrid1.Rows(0).PreviewAppearance.BackColor = Color.Red
