Hi Member,

This code you are showing is not very safe - you say the cell[0] has the index, string comparison etc. I hope you don't rely heavily on this "index" thing.

Anyway, I assume you have got reasons to use such code...

In WPF you would normally use Binding to bind a list (some enumeration whatever) to your DataGrid. So I'd use Linq to find the desired record (row) in your underlaying datasource, then you can just use the IndexOf method of the ItemCollection.

This code shows the idea - you can run it if you replace MainWindow in a new WPF project with the following.

XML

<Window x:Class="WpfApplication2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <DataGrid x:Name="m_datagrid"/>
        <Button Content="Button" HorizontalAlignment="Left" Margin="422,283,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click"/>

    </Grid>
</Window>

C#

   public partial class MainWindow : Window
    {
        class Record
        {
            public string Key { get; set; }
            public string Value { get; set; }
        }

        List<Record> m_list = new List<Record> 
        {
            new Record { Key = "A", Value = "aaa"},
            new Record { Key = "B", Value = "bbb"},
            new Record { Key = "C", Value = "ccc"}
        };

        public MainWindow()
        {
            InitializeComponent();

            m_datagrid.ItemsSource = m_list;

        }

        int GetRowIndex(string strKey)
        {
            int iIndex = -1;

            // search the record given by the key (id) in the underlaying datasource (a simple List in this case)
            Record record = m_list.FirstOrDefault(r => r.Key == strKey);
            // get the index of the found record (or -1 if it wasn't found)
iIndex = m_datagrid.Items.IndexOf(record);

            return iIndex;
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show(this, GetRowIndex("C").ToString());

        }

Just my 2c - maybe it helps you.

Happy coding!
