Creating an unbounded field with button bound to ViewModel command
posted

Guys,

This is a snippet from a Style I need to modify such that the button's command property is bound to an element of IDictionary<string, ICommand> exposed by the ViewModel.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

<Setter Property

="Template">

 

 

 

<Setter.Value

>

 

 

 

<ControlTemplate TargetType="{x:Type igDP:CellValuePresenter

}">

 

 

 

<igWindows:CardPanel Width="{TemplateBinding Width}" Height="{TemplateBinding Height

}" >

 

 

 

<Button Style="{DynamicResource btnRemove}" Width="14" Height="14"

 

 

Content="{TemplateBinding Content}"

 

 

CommandParameter="{Binding ViewID

}"

 

 

Command="{Binding Commands[AcknowledgeErrorCmd]}" />

 

 

 

</igWindows:CardPanel

>

 

 

 

<ControlTemplate.Triggers

>

 

 

 

<Trigger Property="HighlightAsPrimary" Value

="True"/>

 

 

 

<Trigger Property="IsFieldSelected" Value

="True"/>

 

 

 

<Trigger Property="IsSelected" Value

="True"/>

 

 

 

<Trigger Property="IsActive" Value

="True"/>

 

 

 

<Trigger Property="IsMouseOver" Value

="True"/>

 

 

 

</ControlTemplate.Triggers

>

 

 

 

</ControlTemplate

>

 

 

 

</Setter.Value

>

 

 

 

</Setter

>

Problem is, the binding is not working.  

Now, if I replace the button with a TextBlock with the following binding:

 

 

 

<TextBlock Text="{Binding ElementName=root, Path

=DataContext.ViewID}"/>

I get DataItem.ToString() displayed, where DataItem is an instance of my data class. 

Can you please help me understand where the disconnect is from CellValuePresenter to my main view?

TIA,

Klaus
