Is there a way have a single textbox bind to two things. I want to have one binding set to "OneWay" and the Other set to "OneWayToSource". Basically I want to combine these two textboxes into one (and preferably with little to no code behind).
<TextBox Text="{Binding Path=ActionParameter.Value, Mode=OneWayToSource}" /> <TextBox Text="{Binding Path=StatusSignal.Value, Mode=OneWay}" /> You can use MultiBinding to set 2 or more bindings to your TextBox
Example:
<TextBox> <TextBox.Text> <MultiBinding StringFormat="{}{0}{1}"> <Binding Path="ActionParameter.Value" Mode="OneWayToSource" /> <Binding Path="StatusSignal.Value" Mode="OneWay" /> </MultiBinding> </TextBox.Text> </TextBox> But depending on what you need to do with the 2 properties you may need to use a IMultiValueConverter to process the properties.
Example:
<TextBox> <TextBox.Resources> <local:TextConverter x:Key="MyConverter"/> </TextBox.Resources> <TextBox.Text> <MultiBinding Converter="{StaticResource MyConverter}"> <Binding Path="ActionParameter.Value" Mode="OneWayToSource" /> <Binding Path="StatusSignal.Value" Mode="OneWay" /> </MultiBinding> </TextBox.Text> </TextBox>
