Question

I have a combobox inside of my WPF DataGrid. It is created like this:

<DataGridTemplateColumn Header="Account">
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Path=Account, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
    <DataGridTemplateColumn.CellEditingTemplate>
        <DataTemplate>
            <ComboBox ItemsSource="{DynamicResource Accounts}" SelectedValue="{Binding Path=Account, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Height="23" IsTextSearchEnabled="True"/>
        </DataTemplate>
    </DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>

The DataContext for this datagrid is an ObservableCollection. The Transaction class has a Property called “Account” Below is how I create this property:

public string Account
{
    get { return account; }
    set { account = value; NotifyPropertyChanged("Account"); }
}

What am I doing wrong here? When I choose an item from the ComboBox, nothing is displayed after I click outside of the box. When I set a break point in the Set method of the Account Property, the value is null.

Fixed my issue. I had to set the Text property binding.

<DataGridTemplateColumn.CellEditingTemplate>
    <DataTemplate>
        <ComboBox  ItemsSource="{DynamicResource Accounts}" Text="{Binding Path=Account}" Height="23" IsTextSearchEnabled="True"/>
    </DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
