How to prevent the Focus Rectangle from being drawn in the Tabs?

4 Feb 20251 minute to read

You can easily do this by handling the DrawItem event, adjusting the DrawTabEventArgs and delegating drawing to the default drawing logic.

C#

private void TabControlExt_DrawItem(object sender, Syncfusion.Windows.Forms.Tools.DrawTabEventArgs drawItemInfo)

{

// To indicate that the tab gets drawn as if it’s not focused (without the focus rect).

drawItemInfo.State &= ~DrawItemState.Focus;



// Then forward drawing to default drawing logic.

drawItemInfo.DrawBackground();

drawItemInfo.DrawInterior();

drawItemInfo.DrawBorders();

}

VB.NET

Private Sub TabControlExt_DrawItem(sender As Object, drawItemInfo As Syncfusion.Windows.Forms.Tools.DrawTabEventArgs)

'To indicate that the tab gets drawn as if it’s not focused (without the focus rect).

Dim & As drawItemInfo.State = ~DrawItemState.Focus



'Then forward drawing to default drawing logic.

drawItemInfo.DrawBackground()

drawItemInfo.DrawInterior()

drawItemInfo.DrawBorders()

End Sub
