    I assume there is no built-in validation in the Blazor edition of Flexgrid (yet) correct? https://demos.componentone.com/aspnet/5/mvcexplorer/FlexGrid/BuiltInValidation

    Any plans to add this functionality?

    If not or until added:

    How can I add a tooltip (red triangle) to a cell?

    How can I customize the row header (e.g. red background)

    Thank you

    Hi Daniel,

    The shared sample is for the MVC app which works purely on the client side. This checks the value of the client and adds the CSS accordingly.

    For Blazor, this can be achieved by handling the CellEditEnding event to validate the input and PrepareCellForStyle to style the cell.

    We are sorry for the inconvenience but currently the Tooltip for FlexGrid is not supported. This has been forwarded to the concerned team with the internal tracking id C1-5624
