Fairly new to the world of WPF. I've got data binding to a view model in the past just fine when it's a basic tree of elements under the root .
Like this works fine:
<TextBox x:Name="emailTxt" Grid.Row="6" Grid.Column="2" Text="{Binding Path=Email}">
My Email string object binds and displays in the above textbox appropriately.
However, when using a DataTemplate nothing seems to work. I'm not sure if its a combination of not implementing the DataTemplate correctly or something with the TabControl. I've tried switching around the logic a bit based on other sources (setting DataType on the template, etc), but that's been no good.
Here's the example of kind of what I have currently (sorry the template is long do the needing a large grid of 3x40 cells): this template exists under Windows.Resources.
<DataTemplate x:Key="commGridTemplate" DataType="{x:Type ViewModels:CommViewModel}">
<ScrollViewer Margin="10,30,60,30">
<Grid Name="CommGrid" IsSharedSizeScope="True"> <!-- DataContext="{Binding}" -->
<Grid.ColumnDefinitions>
<ColumnDefinition Name="RowBoxCol" Width="0.2*"></ColumnDefinition>
<ColumnDefinition Name="ChannelCol" Width="1*"></ColumnDefinition>
<ColumnDefinition Name="FrequencyCol" Width="1*"></ColumnDefinition>
<ColumnDefinition Name="DescriptionCol" Width="2*"></ColumnDefinition>
</Grid.ColumnDefinitions>

Right now I'm just trying to get the ExampleBox at Grid 1,1 to bind to the ExampleText object that exists within my CommViewModel. I set a namespace at the top for xmlns:ViewModels="clr-namespace:CommGUI.ViewModels" so hopefully it's accessible. I also set ViewModel as the DataContext of the main window within MainWindow.xaml.cs
ViewModels.CommViewModel viewModel = new ViewModels.CommViewModel(Convert.ToString(id));
this.DataContext = viewModel;
Any input would be much appreciated.
**EDIT: ** In response to a comment: my grid is a 3x40 consisting of all textboxes. 3 columns, 40 rows. The top row is made up of disabled boxes to act as the header for each column. The columns are Channel, Frequency, and Description. I imagine each row will contain data from a bound object from CommViewModel.
I think you are going about it the wrong way. What you probably need is to create a List that has the 3 parts you need... Frequency, description, and any other things you want. Make the List<> public via a getter/setter.
In your form, create a DataGrid control and set its items source to the List<> and you are almost done.
I have created a sample project called Help1, so change the context, or copy paste into your project to see it work. Below is the MainWindow.xaml showing the use of a datagrid.
<Window
