Dear Friends,
I am having a user defined control of interface type ISaveable (my user defined interface) as follows,
I have a button on the main form that is enabled if the control is Isavable.
May be I can make more sense in following code.

XML

<Button Name="btnSave" Content="Save" IsEnabled="{Binding   ElementName=expMaster, Path= (expMaster.GetType()==typeof(ISavable)) }" />

where expMaster is a user defined control instantiated as,

XML

<Employee:EmployeeMaster x:Name="expMaster"  />

where Employee master is inherited from interface ISavable.

please let me know how can I bind the isEnabled property of my button to the user defined object type
I don't want to create issavable property in my user defined control EmployeeMaster.

Best regards

Solution 1

Instead of the path try and use a value converter (IValueConverter).
In the converter check the value.GetType() and return True or False as needed.
