Hi

I don't understand what datatype this column binds to.

I have a collection of objects with a bitmap property, when binding to the grid, nothing is displayed.

What datatype am I suppose to use? Image, Byte() ? I cant seem to find much documentation on this.

Thanks

NET 3.5 - Connect to DB

OK so I am new to both .NET 3.5 and Winforms. I have experience connecting to a db in the web.config file, but when it comes to the app.config, I am having difficulty.

I am trying to populate the ComboBox with data from a Stored Procedure.

Can anyone point me in the right direction, I think I must be close.

RadObjectCustomPropertyDescriptor Error

Support:
I was using trial version of Rad control and created few test screens and everything went on well except the popup.

I recently bought RadControlsWinforms_Q3_2007_SP1_dev_setup.exe .
When I installed the version I get the following error on the screen using panel.

Telerik.WinControls.Design.RadObjectCustomPropertyDescriptor.SetValue(Object component, Object value)

When I checked your VB.NET sample ,panelbar-First Look>Form1.vb throws the same exception.The trial version I tried before the purchase is
RadControlsWinforms_Q3_2007_trial_setup.exe

I'm really struck now,the main page of my application is using the Panel and I can rul the apps ;-).

Not sure whether the trial version got messed up with the actual?

Appreciate if you can help me to save me from redevloping the screen due to some control problem.

Regards,
Ganeshram.M

RadDockableWorkSpace problem

Hello,

The DockingSmartPartInfo is somehow being applyed too late (after the view is visible), making the view being shown on a small size and after loading it's shown with the Fill option as i ddi Dockposition.Fill.

It would had been nice to be able to use an interface like IDockingSmartPartInfo on the View itself.

DockingSmartPartInfo ovzRelatieInfo = new DockingSmartPartInfo();
ovzRelatieInfo.Title = "Overzicht relaties";
ovzRelatieInfo.TabStripVisible = false;
ovzRelatieInfo.Width = 700;
ovzRelatieInfo.Height = 500;
ovzRelatieInfo.DockPosition = Telerik.WinControls.Docking.DockPosition.Fill;
this.ShowViewInWorkspace<OvzRelatieView>("OvzRelatie", WorkspaceNames.DockableWorkspace, ovzRelatieInfo);
