WPF UI DataGrid Exception

KeesBL commented 1 year ago

Describe the bug

Sorting the data grid several times in quick succession will cause an exception: "System.InvalidOperationException: ''ContentControl' TargetType does not match type of element 'DataGridColumnFloatingHeader'.'" The issue isn't reproducible every time, but does happen consistently. A stack trace from the exception is attached.

To Reproduce

Run Wpf.Ui.Demo and switch to the Data page. Scroll to the WPF UI DataGrid. Click the headers quickly, the exception happens pretty reliably for me within about 15 seconds.

Expected behavior

I'd expect the control to be able to be sorted quickly without raising an exception that crashes the program.

An update: the exception (System.InvalidOperationException: ''ContentControl' TargetType does not match type of element 'DataGridColumnFloatingHeader'.') occurs reliably when dragging DataGrid or WPF UI DataGrid columns to reorder them.

Hey I am facing the same issue, Were you able to find any solution or disable reordering ?

Setting CanUserReorderColumns to False disables the behavior, but of course also disables users' ability to reorder their grids. Hopefully a temporary fix!
