Property Paths

You can access this nested property as listed below:

Object Type	Path to AllowSelectSingleRowOnly
ASPxGridView	.SettingsBehavior .AllowSelectSingleRowOnly
GridViewProperties	.SettingsBehavior .AllowSelectSingleRowOnly

Remarks

The AllowSelectSingleRowOnly property is in effect when row selection is enabled. To enable row selection, specify one of the following properties:

• AllowSelectByRowClick
• ShowSelectCheckbox
• SelectAllCheckboxMode
• ShowSelectButton
• Selection

When the checkbox selection mode is enabled (the ShowSelectCheckbox property is set to true), the AllowSelectSingleRowOnly property defines the editor type (check box or radio button) within the command column cells.

ASPX

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

Limitations

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

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

• For a grid within the ASPxGridLookup control, the AllowSelectSingleRowOnly property synchronizes its value with the ASPxGridLookup.SelectionMode property value.
