How to get datagrid selected row value in textbox

Question

I want datagrid selected value in textbox.

I tried this code

private void datagrid1_SelectionChange(object Sender, RoutedEventArg e)
{
    var selectedrow = datagrid1.selectedItem as datarowview;
    var id = selectedrow["Tagid"];  // Here I get error that object reference is not set is an instance of an object 
    string s = conver.tostring(id);
    txttextbox1.text= s;
}

It works fine.

But when I refresh (or reload) datagrid1 then selectionChange throws an error:

Object reference is not instance of an object

In your XAML

  <DataGrid Name="MyGrid" AutoGenerateColumns="False"   SelectionChanged="DataGrid_Details_SelectionChanged">

and in .cs file add

   private void DataGrid_Details_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        try
        {
            var row_list = GetDataGridRows(MyGrid);
            foreach (DataGridRow single_row in row_list)
            {
                if (single_row.IsSelected == true)
                {
                    //Get your value over here
                }
            }

        }
        catch { }
    }

    public IEnumerable<DataGridRow> GetDataGridRows(DataGrid grid)
    {
        var itemsSource = grid.ItemsSource as IEnumerable;
        if (null == itemsSource) yield return null;
        foreach (var item in itemsSource)
        {
            var row = grid.ItemContainerGenerator.ContainerFromItem(item) as DataGridRow;
            if (null != row) yield return row;
        }
    }

Thank again for your valuable solution . And This work for me perfectly. — Dipika, Mar 20 '15 at 05:44
