Hi All,

Perhaps its because its been a long week, but I just can't seem to figure
out how to bind data in a DataTemplate using DataContext.

The following is in the XAML code:
<Button x:Name="btnRegularDataContext" Margin="5">
<TextBlock Text="{Binding}" />
</Button>

<Button x:Name="btnInDataTemplate" Margin="5">
<Button.ContentTemplate>
<DataTemplate>
<TextBlock Text="{Binding}" />
</DataTemplate>
</Button.ContentTemplate>
</Button>

And in the code-behind:
btnRegulareDataContext.DataContext = DateTime.Now.ToShortString();
btnInDataTemplate.DataContext = DateTime.Now.ToShortString();

The first button shows the time, the second does not. What am I missing?!?

Thanks....

Hi Paul,

After you set the DataContext property of the Button to a data source, you
also need to bind the Content attribute of the Button as follows:

<Button x:Name="btnInDataTemplate" Margin="5" Content="{Binding}">
...
</Button>

so that the DataTemplate will find the bound data source.

Hope this helps.
If you have any question, please feel free to let me know.

Sincerely,
