Hi,

local is just a namespace you need to setup, in my project called ComboBoxTest this is the whole xaml. Take a look at the bolded line, replace the ComboBoxTest with your namespace and that should fix it.


<UserControl x:Class="ComboBoxTest.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:sdk="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"
    xmlns:local="clr-namespace:ComboBoxTest"
mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="400">

    <UserControl.Resources>
        <local:MainPageViewModel x:Key="vm" />
    </UserControl.Resources>

    <Grid x:Name="LayoutRoot" Background="White" DataContext="{StaticResource vm}">
        <sdk:DataGrid ItemsSource="{Binding Orders}">
            <sdk:DataGrid.Columns>
                <sdk:DataGridTemplateColumn x:Name="CustomerColumn" Header="Customer">
                    <sdk:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <ComboBox ItemsSource="{Binding Customers, Source={StaticResource vm}}" />
                        </DataTemplate>
                    </sdk:DataGridTemplateColumn.CellTemplate>
                </sdk:DataGridTemplateColumn>
            </sdk:DataGrid.Columns>
        </sdk:DataGrid>
    </Grid>
</UserControl>

The DataContext of the DataGrid is the reason why you are not able to bind to orders. You need to have some way of binding back to the root datacontext (The ViewModel)

This is not so easy in SL4 but will become much easier in SL5, for now you could do something like this:

    <UserControl.Resources>        <local:MainPageViewModel x:Key="vm" />    </UserControl.Resources>     <Grid x:Name="LayoutRoot" Background="White" DataContext="{StaticResource vm}">        <sdk:DataGrid ItemsSource="{Binding Orders}">            <sdk:DataGrid.Columns>                <sdk:DataGridTemplateColumn x:Name="CustomerColumn" Header="Customer">                    <sdk:DataGridTemplateColumn.CellTemplate>                        <DataTemplate>                            <ComboBox ItemsSource="{Binding Customers, Source={StaticResource vm}}" />                        </DataTemplate>                    </sdk:DataGridTemplateColumn.CellTemplate>                </sdk:DataGridTemplateColumn>            </sdk:DataGrid.Columns>        </sdk:DataGrid>    </Grid>

I have done what Mark's advice and still can't populate combobox. I want to Display all the ContactName of the Customer Table in that combobox. Take note that the combobox is within a Datagrid.
 
As you can see were a VB programmer(WinForm) trying to migrate to WPF or Silverlight, we have no expierence in regards to XAML thats why were having a hard time on this.
 
Thank you for helping us..

For your combobox, you want to bind ItemsSource to the navigation property that contains the possibilities for that column., and the SelectedItem to a scalar property on the current item. We have a Silverlight code sample which demonstrates this:

You need to set the ItemsSource of the ComboBox to be databound to a property such as "Customers" which is implemented as an ObservableCollection or some other kind of collection.

You then need to populate this collection with the list of customers.

<ComboBox SelectedItem={Binding Order.Customer}" ItemsSource="{Binding Customers}" />

public ObservableCollection<Customer> Customers { get; set; }


Something like that.
