Cannot switch tabs in designer

I am creating a .NET 6 WinForms application using TabControlAdv and TabPageAdv. When I drop the TabControlAdv on the form and add tab pages, only the first tab page is accessible. I cannot click on the other pages to get access to the client area. I'm using version 20.1.0.58. This does not happen with a .NET 4.x application using an older version (i.e., 18.x). Is there some kind of compatibility

Hi Kevin,


Currently, there is no support for switching the tabs in the designer of .netCore projects. We have already created feedback regarding this support.


Feedback link-https://www.syncfusion.com/feedback/20783/switching-between-tabs-in-net-5


We will implement this feature in any of our upcoming releases.

Hi Aaron LeMasters,


Currently, we are exploring the feasibility of implementing a feature that allows customization of settings for custom controls in .NET Core. The designer lacks full support for this purpose, making it challenging to interact with controls through the smart tag. Detailed information can be found in the GitHub query below.

Hi!
Are there any updates on this?
I am using TabControlAdv very often in my project, and would like to update from net472 to net8.

This is the reason i'm not doing the switch to net8

Hi Michael,


We are currently working on implementing designer support for .NET Core. Please refer to the provided feedback link for future updates. This feature will be included in an upcoming release.

Would it be possible to introduce a property SelectedIndex in the meantime?
Then you could switch the tabs like this.

At the moment the control is not really usable due to the lack of designer support.


Is there a timeline for the support? The feedback link was created 3 years ago....

I have seen there is a SelectedIndex and a SelectedTab Property. But it is not accessable throw the designer.
Making it acessable would help for the moment...

Hi Michael Sandler,

We have included the fix for the reported issue “TabControlAdv failing to switch tabs in the designer” in our Weekly NuGet release version 28.1.39 which is available for download ( https://www.nuget.org/).

Root Cause: The issue occurred because a required design-time event was not properly implemented, which prevented tab switching via mouse clicks in the designer

We thank you for your support and appreciate your patience in waiting for this update. Please get in touch with us if you require any further assistance.

Regards,
Sekar Sivalingam
