GridViewDataColumn.UnGroup() Method
Clears the grouping applied to the column.
Namespace: DevExpress.Web
Assembly: DevExpress.Web.v24.1.dll
NuGet Package: DevExpress.Web
Declaration
Remarks
When you call a column’s server-side UnGroup
method, the grid behaves as follows:
- Clears the grouping applied to the column.
- Sets the
GroupIndex
property to-1
.
To group data by the values of a particular column on the server side, call the ASPxGridView.GroupBy or GridViewDataColumn.GroupBy method.
For more information on grouping in the grid, refer to the following topic: ASPxGridView - Group Data.
<dx:ASPxGridView ID="grid" runat="server" AutoGenerateColumns="False" KeyFieldName="CustomerID"
OnCustomCallback="grid_CustomCallback">
<Columns>
<dx:GridViewDataTextColumn FieldName="Country" VisibleIndex="0" GroupIndex="0" />
<%--...--%>
</Columns>
<Settings ShowGroupPanel="true" />
</dx:ASPxGridView>
protected void grid_CustomCallback(object sender, ASPxGridViewCustomCallbackEventArgs e) {
var column = grid.Columns["Country"] as GridViewDataColumn;
column.UnGroup();
}
