Using a Usercontrol inside Datatemplate

Using a Usercontrol inside Datatemplate

I have a datatemplate like this: <DataTemplate x:Key="TplFullImages"
DataType="{x:Type cControl:FullVisableImageControl}"> </DataTemplate>
cControl:FullVisableImageControl is my usercontrol However I still need
the Usercontrol to have the parameters when it initialises. How can I
achieve this? Or what options do I have?
