Hi Dani,
Query: VerticalContentAlignment doesn't work
We have checked your query and would like to inform you that VerticalContentAlignment does not go to the top in SfTextBoxExt because we styled the vertical alignment of the MultiSelectMode token with the center by default. You can also edit that default style in MainPage.Xaml is like below code snippet to achieve your requirement. Please refer to below code snippet for this
<WrapPanel x:Name="Multi_Panel"
MinHeight="18"
Orientation="Horizontal"
VerticalAlignment="Top">
We have attached the modified sample for your reference. Please let us know if the reported issue was resolved on your side.
Regards,
Arunachalam K
