I also get the same exception once I Bind data to the chart, or when, in design time, i browse through the list of chart types and select one or another.

the following stack trace:

If you watch this code in designer preview, then you could select another chart type.
Just klik in the properties panel of the VS designer and select the property 'DefaultType'.  (make sure only the cursor is in that property and don't drops down a combo menu.'

No just select a consequetive number of chart types and you'll get a nice Exception dialog:

The control Telerik.WinControls.UI.RadChart has thrown an unhandled exception in the designer and has been disabled.

Exception: Object reference not set to an instance of an object.

Stack trace: 
    at     Telerik.WinControls.UI.RadChart.GetImage()
    at     Telerik.WinControls.UI.RadChart.OnPaint(PaintEventArgs e)



Secondly i get the same error during runtime when I try to bind the chart to my data source (eventhough the preview chart draws well).

Strangely my databinding used to work with an older Telerik version.

Kind regards,

Jack.

PS: How can I add myself again as developer on our account. I've removed myself, but there is no way to readd myself.

Hello Evtim,

For your information:
The latter error I was speaking about is the following:

   at Telerik.Charting.Chart.GetImage(Int32 width, Int32 height)
   at Telerik.Charting.Chart.GetImage()

   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

It occurs when I databind the chart.


Kind regards,

Hi Jack,

You need to contact the license holder as he is the only one that can add you as a developer.

On the code sent - unfortunately, there are some resources missing. Please, create a Support thread and attach the whole project (you won't be able to do that before you are added back as a developer).
