Pre-setting the ComboBox selection in XAML

[kender_a]

Colleagues,

I would like to pre-set the ComboBox in XAML. For example, there are 3 options: “4800”, “9600”, “19200”. I know that the text of the pre-selected item is “9600”. Which properties of ComboBox should I assign? Is it possible to do it entirely in XAML without writing code for looking up the index from the item text.

So far, I’ve tried this:

        <ComboBox Name="cboBaudRate" 
                  Grid.Column="1" Grid.Row="1" Margin="0,2,0,0" HorizontalAlignment="Left" Width="72" Height="20" VerticalAlignment="Top"
                  SelectedItem="9600" IsSynchronizedWithCurrentItem="True"
                  ItemsSource="{Binding Source={StaticResource SerialPortOptions}, XPath=./BaudRates/BaudRate }" />

But it keeps selecting the 1st option “4800”, probably because the index is initially set to 0.

Suggestions, insight, references are much appreciated.

Resolved. Assigning SelectedValue instead of SelectedItem worked.

The working XAML looks like this:

        <ComboBox Name="cboBaudRate" 
                  Grid.Column="1" Grid.Row="1" Margin="0,2,0,0" HorizontalAlignment="Left" Width="72" Height="20" VerticalAlignment="Top"
                  SelectedValue="9600"
                  ItemsSource="{Binding Source={StaticResource SerialPortOptions}, XPath=./BaudRates/BaudRate }" />
