BorderStyle not responding when using a TabbedMDIManager

Hi there,
Using syncfusion 4.302.0.30 I'm trying to show all the MDITabPanels managed by a TabbedMDIManager with a 'None' BorderStyle but the control seems not to be responding. I want them to seem flat controls but I can't. It always seems to be sunken into the parent MDI.

I'm using the next code in order to make it works:

void _TabbedMDIManager_TabControlAdding ( object sender, TabbedMDITabControlEventArgs args )
args.TabControl = new MDITabPanel ( this._TabbedMDIManager );
args.TabControl.TabStyle = typeof ( Syncfusion.Windows.Forms.Tools.TabRendererOffice2003 );
args.TabControl.Alignment = TabAlignment.Bottom;
args.TabControl.BorderStyle = BorderStyle.None;


private void TabControl_ControlAdded ( object sender, ControlEventArgs e )
if ( e.Control is TabPageAdv )
(( TabPageAdv ) e.Control ).BorderStyle = BorderStyle.None;

Could someone please tell me what I'm doing wrong?

Thank's in advance!

You should use TabbedMDIManager.TabControlAdded event instead of TabbedMDIManager.TabControlAdding events.

this.tabbedMDIManager.TabControlAdded += new TabbedMDITabControlEventHandler(tabbedMDIManager_TabControlAdded);

private void tabbedMDIManager_TabControlAdded(object sender, TabbedMDITabControlEventArgs e)
e.TabControl.TabStyle = typeof ( Syncfusion.Windows.Forms.Tools.TabRendererOffice2003 );
e.TabControl.Alignment = TabAlignment.Bottom;
e.TabControl.BorderStyle = BorderStyle.None;

Please let me know if this works for you. Thanks for using Essential Tools.

Hi there again,

I've found my bordered style window. It was the MdiClient attached to my MDI main window the one who was drawing a BorderStyle.Fixed3D border not the tabbed windows. In order to solve it, I've searched the MdiClient and I've changed its border style to none and now it's working fine!

Thank's anyway for your quick response.

I'm not sure if I understand this....

System.Windows.Forms.Form doesn't have a MdiClient member, so what do you mean by "MdiClient attached to my MDI main window".

Also MdiClient doesn't have a BorderStyle member. Am I missing something ?

Hi Daniel,

This issue is not related with Syncfusion TabbedMDI Manager.

By the design of .NET framework, MdiClient doesn't have a BorderStyle member.

Thanks for using Syncfusion Products.

Best Regards,
