get reference to radgrid inside another radgrid

[cognos s]

Here is what I have:
I have a radgrid and in one of its column I show another radgrid. Parent(StudentsGrid) and Child(AttendanceGrid). For each student record there can be more than one attendance. I provide a checkbox in attendancegrid so the user can delete a particular attendance. I would like to get the selected attendance records. below is the code that I have until now. I would like to do this on client side not on server side.

pls let me know how to solve this.

 

 

 

 

function rowSelected() {

 

 

 

      var grid = $find("<%= rgStudents.ClientID %>");

 

 

      var masterTable = grid.get_masterTableView();

 

 

      var rows = masterTable.get_dataItems();

 

 

      for (var i = 0; i < rows.length; i++) {
             var cell = masterTable.getCellByColumnUniqueName(rows[i], "Attendance");

 

              // how to get the reference to attendance radgrid and loop through its checked items????
}

 

 

 

 

 

<telerik:RadGrid ID="rgStudents" runat="server" AutoGenerateColumns="false">                     
            <MasterTableView DataKeyNames="StudentId">
                <Columns>     
                   
                    <telerik:GridBoundColumn DataField="StudentId" UniqueName="StudentId" Visible="false" />
                    <telerik:GridBoundColumn DataField="FName" UniqueName="FName" HeaderText="First Name" />
                    <telerik:GridBoundColumn DataField="LName" UniqueName="LName" HeaderText="Last Name" />                   
                     <telerik:GridTemplateColumn HeaderText="Attendance" UniqueName="Attendance">
                        <ItemTemplate>
                            <telerik:RadGrid ID="rgAttendance" runat="server" AutoGenerateColumns="false" AllowMultiRowSelection="true" >
                               <ClientSettings>
                                        <Selecting AllowRowSelect="true" />
                                         <ClientEvents OnRowSelected="rowSelected" OnRowDeselected="rowDeselected" />                               
                               </ClientSettings>
                               <MasterTableView DataKeyNames="AttendanceID">
                                   
                                    <Columns>
                                        <telerik:GridBoundColumn DataField="AttendanceId" UniqueName="AttendanceId" Visible="false" />                                       
                                        <telerik:GridBoundColumn DataField="CourseNo" HeaderText="CourseNo" />
                                        <telerik:GridBoundColumn DataField="Attendance" HeaderText="Date" />                                       
                                        <telerik:GridClientSelectColumn UniqueName="checkboxDelete"/>
                                    </Columns>
                               </MasterTableView>                               
                            </telerik:RadGrid>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>             
                </Columns>       
            </MasterTableView>
        </telerik:RadGrid>

Hello Cognos,

Try out the following code to access selected items in the nested RadGrid:
js:

function rowSelected(sender,eventArgs)
     {
          var grid = $find("<%= RadGrid1.ClientID %>");
          var masterTable = grid.get_masterTableView();
          var rows = masterTable.get_dataItems();
          for (var i = 0; i < rows.length; i++)
          {
             var cell = masterTable.getCellByColumnUniqueName(rows[i], "Attendance");
          }
           var selectedRows = sender.get_masterTableView().get_selectedItems();// where sender is the rgAttendance grid

     }

Hope this helps..
Princy.

Can you pls modify my javascript and get it working?

And when you are done, will you write my code for me, too?  ;-)

Seriously, is anybody at Telerik rewriting the client-side API documentation?  It is sooooo horrible!

Cheers!
Mark
