Title Body

I've got a property which is a database data type ( char , DateTime , int , float etc...) and I want to change the control used to enter a value of the selected type. So for text values I want a TextBox and for date values I want a DatePicker . One way I thought about doing it was to have one of each control on my form and set their Visibility using an appropriate IValueConverter implementation. I know this will work, but it would create a lot of code and doesn't feel very nice. The other way I thought was to use a ContentPresenter and set its content with a Style and DataTriggers but I can't get it to work. <Style x:Key="TypedValueHelper" TargetType="{x:Type ContentPresenter}"> <Style.Triggers> <DataTrigger Binding="{Binding Path=DataType}" Value="Char"> <Setter Property="Content" Value="???"/> </DataTrigger> <DataTrigger Binding="{Binding Path=DataType}" Value="Date"> <Setter Property="Content" Value="???"/> </DataTrigger> <DataTrigger Binding="{Binding Path=DataType}" Value="Integer"> <Setter Property="Content" Value="???"/> </DataTrigger> </Style.Triggers> </Style> If anyone can fill in my "???" or offer a better solution please do.
