Question

I have a DataGrid with data populated from an XML binding.

I want to know how I can obtain the selected row in C#, more specifically I want to return the value of the ‘ID’ from the selected row from my dataset.

I can get the entire row contents with:

 var downloadlistselected = downloadList.SelectedValue.ToString();

However, I only want the contents from the first column.

Can anyone help?

XAML

  <Grid.DataContext>
            <XmlDataProvider Source="E:\downloader\downloadConfig.xml" XPath="/xservdownload/downloadItem"></XmlDataProvider>
        </Grid.DataContext>

        <DataGrid x:Name="downloadList" Height="191" VerticalAlignment="Top" ItemsSource="{Binding}" AutoGenerateColumns="False" AlternatingRowBackground="Gainsboro" IsReadOnly="True" SelectionChanged="DownloadListSelectionChanged" DataContext="{Binding}" IsSynchronizedWithCurrentItem="True">
            <DataGrid.Columns>
                <DataGridTextColumn Header="ID" Binding="{Binding XPath=ID}" Width="50"></DataGridTextColumn>
                <DataGridTextColumn Header="Name" Binding="{Binding XPath=Name}" Width="350"></DataGridTextColumn>
                <DataGridTextColumn Header="Status" Binding="{Binding XPath=Status}" Width="100"></DataGridTextColumn>
            </DataGrid.Columns>

Answer 1

Something along those lines should do:

var item = (XmlNode)downloadList.SelectedItem;
var value = item.SelectSingleNode("ID").InnerText;

Key being that the selected item should be an XmlNode from which you can get whatever you need.
