DataControlBase.AutoGeneratingColumn Event

Occurs each time an individual column is auto-generated.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v25.1.Core.dll

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

public event AutoGeneratingColumnEventHandler AutoGeneratingColumn

VB.NET

Public Event AutoGeneratingColumn As AutoGeneratingColumnEventHandler

Event Data

The AutoGeneratingColumn event's data class is DevExpress.Xpf.Grid.AutoGeneratingColumnEventArgs.

Remarks

Use the AutoGeneratingColumn event to change or cancel an automatically generated column when it is created.

The following example prevents a grid from generating a column based on the IsSelected data field:

XAML

<dxg:GridControl AutoGenerateColumns="AddNew"
                 EnableSmartColumnsGeneration="True" 
                 AutoGeneratingColumn="grid_AutoGeneratingColumn"
                 ItemsSource="{Binding Items}">
    <!--...-->
</dxg:GridControl>

C#

private void grid_AutoGeneratingColumn(object sender, DevExpress.Xpf.Grid.AutoGeneratingColumnEventArgs e) {
    if (e.Column.FieldName == "IsSelected") {
        e.Cancel = true;
    }
}

VB.NET

Private Sub grid_AutoGeneratingColumn(ByVal sender As Object, ByVal e As DevExpress.Xpf.Grid.AutoGeneratingColumnEventArgs)
    If e.Column.FieldName = "IsSelected" Then
        e.Cancel = True
    End If
End Sub
