 Topic: ReportControl in .NET tabcontrolPosted: 30 May 2008 at 11:11am |
|
I am using the ActiveX ReportControl (11.2.0) in a .NET application. I have a TabControl with 2 tabPages. I have a Reportcontrol on each tabpage. All looks fine at design time but when I run the application the Reportcontrol on the unselected tab disappears!!
I've checked the properties and says its visible and positioned correctly - it just not show. If add a Tabcontrol.Selected Index = 1 statement into the form_load event then the control on tab0 disappears.
Is this a bug with the Tab control or the reportcontrol? Any suggestions would be appreciated.
Thanks

I should add that I am using the standard VB.Net winform TabControl - NOT the CodeJock one.

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.

Hi,
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

Hi Aaron, Thanks for responding.
Tried that (and a panel and a group box) - no good.

Hi,
 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.

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.

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

Hi,
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();

I'm glad someone sorted this out. In the end I had to dump the report control as it was causing fatal errors in my interop application. I had to go and buy a proper .NET control. I think the codejock controls are great and brilliant value for money. I just wish they'd bite the bullet and develop some proper .NET controls. Whatever they claim - using active X controls in .NET (especially when you are then interoping them back to VB is fraught with problems. Don't get me started on the hassle I've had skinning VB.NET interop user controls!
