I'm new to the radchart databinding process and after spending an excessive amount of time trying to figure out why I'm not showing any return when I bind to the database I thought I'd ask the sea of experts. I'm sure this has been discussed but when I searched on databinding I only got three posts so please excuse if I am repeating something previously shown.
Attached is a screen shot of what I see currently. The XAxis labels (2008 2009 2010...) are pulled from the database and are displaying as I expected. What isn't showing are the values reflected in the rest of the table. This is pretty straightforward and I'm positive it is something exceptionally simple I'm overlooking but can anyone shed some light on what that might be? I've gotten lost in the mixed examples that came with this add-on so I'm not sure where I'm crossing signals.
Below is the code for my chart.aspx page and it's code behind. The binding taking place in the code behind file is simply binding to a data object that I've created but isn't really relevant to this issue since all it does is open,get, close the database.
Thanks in advance.

DataGrid.ID = "DataGrid";
DataGrid.ViewStateMode = System.Web.UI.ViewStateMode.Enabled;
DataGrid.enablea
DataGrid.AutoGenerateColumns
= true;
DataGrid.MasterTableView.AutoGenerateColumns = false;
DataGrid.MasterTableView.ShowHeadersWhenNoRecords = true;
GetGridHeader(table_name, DataGrid);
DataGrid.DataSource = GetData(table_name);

When i use a RadNumericTextBox inside an InsertItemTemplate of a TreeListTemplateColumn the spin buttons are not rendered completely, just a half of the buttons. Moreover, the width of the textbox is adjusted to 100% independently of the width i specify.

Has anyone figured out a way to change the orientation of a rad tabstrip from vertical to horizontal from javascript? I'm trying to change the orientation if the width of the window is less than 800px and would like for it to be responsive to the size of the window changing.

In a number of applications that I have worked on using Telerik Web UI controls for ASP.NET AJAX, I have use the below pattern to retrieve the row object server-side that the user selects.
protected void MyRadGrid_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
if (e.CommandName == "RowClick")
{
ObjectX a = new ObjectX();
((GridEditableItem)e.Item).UpdateValues(a);
}
}
Previously, as long as ObjectX was a "flat" object - meaning scalar members only - the object "a" would return fully populated with data.
However, since I've downloaded the ASP.NET AJAX Q2 2014, the UpdateValues line causes the application to bomb, specifically because UpdateValues tries to set "a" with some NULL values.
