We checked the TabControl with different child items (just with 2 pieces of TabItem with the following elements on both ):
test: to switch between TabItem1 and TabItem2, we change the Text/Content/Items by Runtime to known values!! (not declarativ way.)
e.g. by user interaction or by some code behind.
-TextBox: ok, works as expected.
-ListBox: ok, works as expected.
-ComboBox: abnormal behaviour -values (items) missing during switching TabItems.
-Usercontrol with native HTML5 element: abnormal behaviour -values (items) missing during switching TabItems.
(InputNumberUserControl with CSharpXamlForHtml5.DomManagement.SetHtmlRepresentation(this, @"<input type=""number"">");)
-DataGrid: even worst: got exception.
We attached our sample code,
Please, check it,
Are you able to reproduce the bugs with the same result as our side?
Is there any estimated time to fix this bug ?
Waiting for you urgent and kind reply,
