Question

I have a ParentView that contains a childView

<UserControl ... x:Name="MyParentView">
     <Grid>
        <sdk:TabControl Name="ContactTabControl">
            <sdk:TabItem Header="Contact" Name="CustomerTabItem">
                <Grid>
                    <Views:CustomerView/>
                </Grid>
            </sdk:TabItem>
        </sdk:TabControl>
    </Grid>
</UserControl>

Within my CustomerView I would like to bind the Firstname textbox to Parent’s DataContext. I have tried this inside the CustomerView:

<TextBox Text={Binding ElementName=MyParentView, Path=DataContext.Firstname} />

I have the feeling that CustomerView won’t be able to see its parent at all, hence the ElementName “MyParentView” would never be found.

What is your advice on this?

Answer 1

I’ve done a similar thing but I just bound it directly to Path considering that if I don’t give it explicit data context, it will lookup the hierarchy and find one that matches.

So this should get you what you want:

<TextBox Text={Binding Path=FirstName} />

if you need to specify explicit datacontext you can always do:

<Grid>
    <Views:CustomerView DataContext={"CustomContextHere"}/>
</Grid>
