Hi,

I have a RadGrid with Hierarchy. I would like to access the DataKeyValues (parent/master table Key Values) in the DetailTables' <CommandItemTemplate>.

Here is the code snippet,

<DetailTables>
                           <telerik:GridTableView DataKeyNames="DV_Correlation_Detail_ID" DataSourceID="dsrcCorrDetail" HierarchyDefaultExpanded="true" ShowHeader="true" ShowFooter="false"
                                    Width="100%" runat="server" AllowFilteringByColumn="False" CommandItemDisplay="Top" Name="Correlation_Detail" EditMode="InPlace">
                                <ParentTableRelation>
                                    <telerik:GridRelationFields DetailKeyField="DV_Correlation_ID" MasterKeyField="DV_Correlation_ID" />
                                </ParentTableRelation>
                                <CommandItemTemplate>
                                    <a href="Javascript:showDialog(1,'derived_variable_selection.aspx?CorrID=<%# Eval("DV_Correlation_ID") %>');"><img style="border:0px" alt="Add Independent Variable" src="images/AddRecord.gif" /> Add Independent Variable </a>
                                </CommandItemTemplate>

When I do "Eval()", it did not complain, and it did not return any value, either. How can I get the key value for each hierarchy detail table within CommandItemTemplate?

Any assistance will be very much appreciated.

Thanks,

Arthur W.

Hello Art,

To achieve your goal you will need to the following code which implements the required functionality:

    
            <a href="Javascript:showDialog(1,'derived_variable_selection.aspx?CorrID= 
        
            <%# ((GridCommandItem)Container).OwnerTableView.ParentItem.GetDataKeyValue("DV_Correlation_ID").ToString() %>');"><img style="border:0px" alt="Add Independent Variable" src="images/AddRecord.gif" /> Add Independent Variable </a>
