GridViewCommandColumn.SelectAllCheckboxMode Property

Specifies the Select All check box visibility and selection mode.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v24.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

[DefaultValue(GridViewSelectAllCheckBoxMode.None)]
public GridViewSelectAllCheckBoxMode SelectAllCheckboxMode { get; set; }

VB.NET

<DefaultValue(GridViewSelectAllCheckBoxMode.None)>
Public Property SelectAllCheckboxMode As GridViewSelectAllCheckBoxMode

Property Value

Type	Default	Description
GridViewSelectAllCheckBoxMode	None	The type of the Select All selection mode.

Available values:

Name	Description
None	The Select All check box is not displayed.
Page	The Select All check box selects and deselects all rows on the current grid page.
AllPages	The Select All check box selects and deselects all grid rows (on all grid pages).

Remarks

Set the SelectAllCheckboxMode property to Page or AllPages to enable the Select All check box. When the SelectAllCheckboxMode property value is None, the control does not display the check box within the command column.

When the row selection changes, the control raises the server-side ASPxGridBase.SelectionChanged or the client-side ASPxClientGridView.SelectionChanged event (based on the ProcessSelectionChangedOnServer property value).

Run Demo: ASPxGridView - Select All Rows

ASPX

<dx:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False" KeyFieldName="EmployeeID">
    <Columns>
        <dx:GridViewCommandColumn VisibleIndex="0" ShowSelectCheckbox="true" SelectAllCheckboxMode="Page"/>
        <%--...--%>
    </Columns>
</dx:ASPxGridView>

Limitations

• When the AllowSelectSingleRowOnly property is set to true, the SelectAllCheckBoxMode property is not in effect.

• When cell merge is enabled, ASPxGridView does not support row selection.
