Hello all.  I am currently having a problem getting the DataKeyValue from
my DetailTables data.  The MasterTableView works fine, however, the
same logic does not work with DetailTables.  I have searched the forum
and cannot fine any reference to this problem before.  Anyone have any
clues?  Code posted below.  Thanks in advance.

<telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" runat="server" Width="97%" AutoGenerateColumns="False"  AllowSorting="True"  ShowStatusBar="true" Skin="Office2007">  
<MasterTableView DataSourceID="SqlDataSource1" DataKeyNames="EventID" AllowMultiColumnSorting="True" Width="100%" Name="EventTable" ClientDataKeyNames="EventID">  
<DetailTables> 
<telerik:GridTableView DataKeyNames="DataID" DataSourceID="SqlDataSource2" 
runat="server" Width="100%" TableLayout="Fixed" Name="DataTable" ClientDataKeyNames="DataID">  
<ParentTableRelation> 
<telerik:GridRelationFields DetailKeyField="EventID" MasterKeyField="EventID" /> 
</ParentTableRelation> 
<Columns> 
<telerik:GridBoundColumn HeaderText="Data ID" DataField="DataID" /> 
<telerik:GridBoundColumn HeaderText="Requirement" DataField="DataReqr" /> 
<telerik:GridBoundColumn HeaderText="Unit Sourced" DataField="DataUS" /> 
</Columns> 
</telerik:GridTableView> 
</DetailTables> 
<Columns> 
<telerik:GridBoundColumn HeaderText="Name" DataField="EventName" HeaderStyle-Width="200px" /> 
<telerik:GridBoundColumn HeaderText="Event AOR" DataField="EventAOR" HeaderStyle-Width="200px" />        
</Columns> 
<GroupByExpressions> 
<telerik:GridGroupByExpression> 
<SelectFields> 
<telerik:GridGroupByField FieldAlias="FY" FieldName="EventFY" /> 
</SelectFields> 
<GroupByFields> 
<telerik:GridGroupByField FieldName="EventFY" /> 
</GroupByFields> 
</telerik:GridGroupByExpression> 
</GroupByExpressions> 
</MasterTableView> 
<ClientSettings ReorderColumnsOnClient="True" AllowColumnsReorder="True">  
<ClientEvents OnRowClick="RowClicked" /> 
<Selecting AllowRowSelect="true" /> 
</ClientSettings> 
</telerik:RadGrid> 
<script type="text/javascript">  
    function RowClicked(sender, args) {  
        if(args.get_tableView().get_name() == "EventTable")  
           alert(args.getDataKeyValue("EventID"));  
       if (args.get_tableView().get_name() == "DataTable")  
           alert(args.getDataKeyValue("EventID"));  
         
    }  
</script>

Hi Joshua,

In your code, I find that you are using the wrong ClientDataKeyName for teh DetailTable. Since you have set the ClientDataKeyNames for the detailtable as DataID, youhave to pass the same field name in the code to access the key value on client:
js:
function RowClicked(sender, args)  
   {   
        if(args.get_tableView().get_name() == "EventTable")   
           alert(args.getDataKeyValue("EventID"));   
        if (args.get_tableView().get_name() == "DataTable")   
           alert(args.getDataKeyValue("DataID"));   
          
    }   

Thanks
Princy.

How on earth did I miss that?  You would think I would have caught it
after staring at that little piece code for 10 minutes.  I will check it
out when I get home today.  Thanks Princy.
