Hello,
I'm currently using a TextBox in one of my forms.
The problem is that the "Value" of the text box is made from a combinaison of different variables, with "ToString()", I cannot bind it to a specific string value.
The [Required] attribute is on a class, which does not contain a string value.
The purpose would be to be able to link "ValueExpression" to any variable like you can do with the validation message " <ValidationMessage For="@AnyTypeRequiredValue"/>". Like this we will be able to have the field colored in red when the class is not filled and when it's not necesseraly a string.
Hope you understood my problem.
Have a nice day
