Datagrid FilterCaseSensitivity

Hello everyone

I want to use FilterCaseSensitivity and FilterMode in Datagrid

However, when FilterCaseSensitivity = "FilterCaseSensitivity.CaseInsensitive" is specified in the property, an error "The name FilterCaseSensitivity does not exist in the current context" appears.

Properties such as ColumnWidth can be used without problems.
Where should I check to resolve this?

Thank you.

You are missing @using Radzen. Check our demos for reference.

Sorry for the rudimentary problem
Thank you!
