Hello, I have following RadGrid containing nested GridTableViews. Every row has CheckBox and I would like to select and deselect them in ClientSide. I have following Javascript code.

function RowSelected(sender, eventArgs) {
  
    var dataItem = sender.get_masterTableView().get_dataItems()[eventArgs._itemIndexHierarchical];
    var str = eventArgs._itemIndexHierarchical; 
  
    if (typeof (dataItem) == "undefined") {
        dataItem = sender.get_detailTables()[0].get_selectedItems()[str];
    }
  
    if (typeof (dataItem) == "undefined") {
        dataItem = sender.get_detailTables()[1].get_selectedItems()[str];
    }
  
  
    if (isDeselecting) {
        if (id == dataItem._itemIndexHierarchical) {
            dataItem.set_selected(false);
            isDeselecting = false;
        }
        else
            id = dataItem._itemIndexHierarchical;
    }
    else if (isDeselecting == false) {
        id = dataItem._itemIndexHierarchical;
        isDeselecting = true;
    }
}

 My aspx Page is declared as followed.

<telerik:RadGrid ID="RadGridSubOrganizations" runat="server" BorderStyle="Solid" AllowFilteringByColumn="false"
 AutoGenerateColumns="false" Visible="true" Width="100%" OnItemCommand="RadGridSubOrganizations_ItemCommand"   
 Height="150px" OnDetailTableDataBind="RadGridSubOrganizations_DetailTableDataBind" 
 OnItemDataBound="RadGridSubOrganizations_ItemDataBound" SortingSettings-EnableSkinSortStyles="true" 
 MasterTableView-ExpandCollapseColumn-Display="true" AllowSorting="false" 
 ShowStatusBar="true" GridLines="None" HeaderStyle-BackColor="#BDBDBD">
  
<MasterTableView CellSpacing="-1" AllowNaturalSort="false" TableLayout="Fixed" Name="Organization" 
  DataKeyNames="ParentOrganizationId,ChildOrganizationId,SubChildOrganizationId"
  ItemStyle-BackColor="#B0C4DE" GridLines="None">                                                                                       
 <HeaderStyle CssClass="HeaderColor" /> 
  
 <DetailTables>
    <telerik:GridTableView DataKeyNames="ParentOrganizationId,ChildOrganizationId" Width="100%" 
    GridLines="None" HeaderStyle-BackColor="#BDBDBD" HeaderStyle-ForeColor="Black" ItemStyle-BackColor="#ADD8E6">                                                                                   
    <DetailTables>                                              
    <telerik:GridTableView DataKeyNames="ParentOrganizationId,ChildOrganizationId,SubChildOrganizationId" Width="100%" 
     ItemStyle-BackColor="#DEF3FA" GridLines="None" HeaderStyle-BackColor="#BDBDBD" HeaderStyle-ForeColor="Black">                                                                                                                          

When event comes to javascript function index of row is in variable eventArgs._itemIndexHierarchical.
But if Row in GridTableView is selected eventArgs._itemIndexHierarchical contains mystic index like: 1:0_0:0_0_0 and exception is thrown when trying to get dataItem from GridTableView. How should I reference to index? Couldn't find any samples or documentation considering this.

How to do this?

Hello Mike,

If you want to get the selected data item in RowSelected event, try the following code snippet.

Java Script:
<script type="text/javascript">
       function RowSelected(sender, eventArgs) {
           var dataItem = eventArgs.get_gridDataItem();//getting selected row(in master/detail table)
    }
</script>

Thanks,
Princy.
