I solved the problem.

Just toggle the visible Property on the activex components on the secondary tabs in the usercontrol load event.

 

axTGrid2.Visible = false;

axTGrid2.Visible = true;

 

maby you also need to call PerformLayout on the tabpages. It depends on the properties.

 

tabPage2.PerformLayout();

Hi,

 

I have the same problem.

Any solution yet?

 

Well that was the last option... for me it was. I think you have to wait for the master himself  Good luck

 

We are trying to avoid using ActiveX controls where possible so I do not really want to go with the Docking Pane control.  I am only using the Report Control because the .NET datagridview control does not support grouping.

 

 

I have also 2 reportcontrols in one form and I use DockPane for this. It looks the same as a tabcontrol.

 

Also with this: picturebox with a reportcontrol in it, then attach the picturebox to the pane. Maybe you could try that.

Hi Aaron, Thanks for responding.

 

Tried that (and a panel  and a group box) - no good.

 

 

You could try to use a picturebox and put the reportcontrol in the picturebox. We have to do this all time with most controls, so why don't you try it

It seems that you only get the issue in a .NET user control.

 

Has anyone experienced this issue before?

 

It's easy to replicate - simply create a new usercontrol.

Put a winforms .NET TabControl on the form and a CodeJock ReportControl on each tab.

 

Create a new windowsapplication and add the usercontrol to form1.

 

Run the app and try changing tabs.  The report controls vanish from all but the first tab shown.

 

The project I'm working on does not give me the luxury of time to spend on this.  If I don't get a solution I will have to dump the ActiveX code jock controls and look at some properly implemented .Net ones.
