DataGrid.AutoGenerateColumns Property

Other Versions

Gets or sets a value that indicates whether columns are created automatically when the ItemsSource property is set.

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

Syntax

Copy

public bool AutoGenerateColumns { get; set; }

XAML Attribute Usage

Copy

<sdk:DataGrid AutoGenerateColumns="bool"/>

Property Value

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

Remarks

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.

Examples

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

Copy


public MainPage()
{
    InitializeComponent();
    DG.DataContext = this.LayoutRoot.Children;
}

private void DG_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
    string headername = e.Column.Header.ToString();

    switch (headername)
    {
        // Cancel the columns you don't want to generate.
        case "Effect":
        case "Clip":
        case "Projection":
        case "OpacityMask":
        case "RenderTransformOrigin":
            e.Cancel = true;
            break;

        // Update column headers when generating.
        case "Opacity":

            e.Column.Header = "Opacity Value";
            break;

        case "UseLayoutRounding":

            e.Column.Header = "Layout Rounding?";
            break;

        case "IsHitTestVisible":

            e.Column.Header = "Hit Test Visible?";
            break;

        case "RenderSize":

            e.Column.Header = "Rendered Size";
            break;
    }

}

XAML
