Patric,

This appears to be a development issue which I will submit to our engineering department.  You will receive more information through the support case that has been opened for you.

Hi,

This issue does not appear to have anything to do with the WinGrid. I can get the same results dropping the default control (DataGridView) onto an UltraPanel.

What's happening here is that when you drop the DataSource onto any container, the designer tries to help you out by increasing the Size of the container so that the default size of the control fits.

But the UltraPanel consists of a couple of nested controls, and the inner controls should never have their Size property set, because the Size of the inner control is controlled exclusively by the outer control.

We will fix this so that the Size property is no longer settable, and therefore does not raise an exception. But you can easily work around this issue by dropping the DataSource onto the form or any other container. And then after all the components and controls are created, just move the DataGridView or the WinGrid into the panel then.

Hello Mike,

thank's for the tip, i will try it next time. As i understand, the UltraPannel is a container, to place several components inside and then place different pannels on different position on a window (a kind of part window to group things together).

Is this the correct usage or do you suggest to use windows dock manager or grid bag layout to place several groups of input controls on a window?

thanks

Patric
