ControlFilterExpression.ControlID Property
.NET Framework (current version)
Gets or sets the ID of the source data-bound control.
Assembly: System.Web.DynamicData (in System.Web.DynamicData.dll)
The ControlID property identifies the source data-bound control from which the data key is selected. The selected data key is then used by the ControlFilterExpression control to build the query.
The following example shows how to use the ControlFilterExpression class to set the ID of the source data-bound control.
<asp:QueryExtender ID="QueryExtenderID"
TargetControlID="TargetDataSourceID" runat="server">
<asp:ControlFilterExpression ControlID="GridViewID" Column="Category"/>
</asp:QueryExtender>
