WPF Commands and Parameters


I'm finding the WPF command parameters to be a limitation. Perhaps that's a sign that I'm using them for the wrong purpose, but I'm still giving it a try before I scrap and take a different tack.

I put together a system for executing commands asynchronously, but it's hard to use anything that requires data input. I know one common pattern with WPF commands is to pass in this. But this will not work at all for asynchronous commands because all the dependency properties are then inaccessible.

I end up with code like this:

<Button Command="{Binding ElementName=servicePage, Path=InstallServiceCommand}">
     <MultiBinding Converter="{StaticResource InstallServiceParameterConverter}">
           <Binding ElementName="servicePage" Path="IsInstalled"/>
           <Binding ElementName="localURI" Path="Text"/>
           <Binding ElementName="meshURI" Path="Text"/>
           <Binding ElementName="registerWithMesh" Path="IsChecked"/>

and also need the InstallServiceParametersConverter class (plus InstallServiceParameters).

Anyone see an obvious way to improve upon this?

Let me point you to my open source project Caliburn. You can find it at here. The feature that would most help solve your problem is documented briefly here
