Namespace:  System.Windows.Controls
Assembly:  System.Windows.Controls.Data (in System.Windows.Controls.Data.dll)

'Declaration
Public Property AutoGenerateColumns As Boolean
<sdk:DataGrid AutoGenerateColumns="bool"/>

Property Value

Type: System.Boolean
true if columns are generated automatically; otherwise, false. The default is true.

Dependency property identifier field: AutoGenerateColumnsProperty

You can modify the Columns collection at run time regardless of whether it contains generated columns. However, if you specify columns in XAML, you should set AutoGenerateColumns to false.

The following code example demonstrates how to set the AutoGenerateColumns property and handle the AutoGeneratingColumn event.


Public Sub New()
    InitializeComponent()
    DG.DataContext = Me.LayoutRoot.Children
End Sub

Private Sub DG_AutoGeneratingColumn(ByVal sender As Object, ByVal e As DataGridAutoGeneratingColumnEventArgs)
    Dim headername As String = e.Column.Header.ToString()

    Select Case headername
        ' Cancel the columns you don't want to generate.
        Case "Effect", "Clip", "Projection", "OpacityMask", "RenderTransformOrigin"
            e.Cancel = True
            Exit Select

            ' Update column headers when generating.
        Case "Opacity"

            e.Column.Header = "Opacity Value"
            Exit Select

        Case "UseLayoutRounding"

            e.Column.Header = "Layout Rounding?"
            Exit Select

        Case "IsHitTestVisible"

            e.Column.Header = "Hit Test Visible?"
            Exit Select

        Case "RenderSize"

            e.Column.Header = "Rendered Size"
            Exit Select

    End Select
End Sub



    <Grid x:Name="LayoutRoot" Background="White">
        <sdk:DataGrid AutoGenerateColumns="True" ItemsSource="{Binding}" 
		x:Name="DG" AutoGeneratingColumn="DG_AutoGeneratingColumn" />

    </Grid>
