Namespace: DevExpress.Web
Assembly: DevExpress.Web.v24.2.dll
Declaration

| Type | Default | Description |
|---|---|---|
| Boolean | true |

Remarks
The AutoGenerateColumns property specifies which data fields are rendered by ASPxGridView. By default, this property is set to true. This forces the grid to render each field from the data source as a column. The order of columns is the same as the order of fields in the data source.
You can also manually control which columns are to appear in the ASPxGridView control by setting the AutoGenerateColumns property to false. In this case, you should manually add columns to the ASPxGridView.Columns collection.
Example
The following example demonstrates how to add a column to the grid when the AutoGenerateColumns property is enabled.
<dx:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="True" DataSourceID="ds"
KeyFieldName="CategoryID" ondatabound="ASPxGridView1_DataBound">
</dx:ASPxGridView>
protected void ASPxGridView1_DataBound (object sender, EventArgs e) {
ASPxGridView grid = sender as ASPxGridView;
if (grid.Columns.IndexOf(grid.Columns["CommandColumn"]) != -1)
return;
GridViewCommandColumn col = new GridViewCommandColumn();
col.Name = "CommandColumn";
// ...
grid.Columns.Add(col);
// ...
}
