javascript error in grid

[Saint]

Hi,
I have created a javascript in my aspx. But I always get 'Rows.length' is null or not an object error message. Please help me. Below is my javascript:

<script type="text/javascript" language="javascript">
        var grid;
        var i;
       
        function GridCreated()
        {
            grid = this;
        }
   
        function HierarchyExpanding(sender, args)
        {         
           PerformAction(grid.MasterTableView)
          
           if (i != 1000)
           {
               if(!confirm("Are you sure you want to expand without update?"))
                {
                    args.set_cancel(true);
                }
                else
                {
                    $find("<%= RadGrid1.MasterTableView.ClientID %>").collapseItem(i);
                }
           )
        }

        function PerformAction(tableview)
        {
            i = 1000;
            for (var j=0; j < tableview.Rows.length; j++)
            {
                if ($find("<%= RadGrid1.MasterTableView.ClientID %>").get_dataItems()[j].get_expanded())
                {
                    i=j;
                }
            }
        }

    </script>

And this is my radgrid:

<telerik:RadGrid ID="RadGrid1" Skin="Default" runat="server" ShowStatusBar="true"
            Width="95%" AutoGenerateColumns="False" PageSize="5" AllowSorting="True" AllowMultiRowSelection="True"
            AllowPaging="True" GridLines="None" AllowAutomaticDeletes="True" AllowAutomaticInserts="True" AllowAutomaticUpdates="True">
        <PagerStyle Mode="NumericPages" />
        <ClientSettings>
            <Selecting AllowRowSelect="true" />
            <ClientEvents OnGridCreated="GridCreated" OnHierarchyExpanding="HierarchyExpanding" />
        </ClientSettings>
        <MasterTableView Width="100%" HierarchyLoadMode="Client" .....

Thanks in advance.

Hello Saint,

Indeed, as the error states, there is no such property. You can get a reference to the master table view and use its get_dataItems() property as in the next line from your code.

Hi,

I am not understand what you mean by : 'You can get a reference to the master table view and use its get_dataItems() property as in the next line from your code.' ? Is that got any documentation?

Thanks.

Hi Saint,

Sure, you will find the Grid client-side API explained here. I hope this helps.
