DataGrid get selected rows' column values

I'm trying to get the values of each column of a selected row in a DataGrid. This is what I have:

private void dataGrid1_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
{
    DataGrid dg = sender as DataGrid;
    Console.WriteLine(dg.SelectedCells[0].ToString());
}

But this does not work. If I do a SelectedCells.Count then I get the correct number of columns but I cannot seem to actually get the values of these columns in the selected row. I've tried for quite a while with no luck! Here is my XAML:

<Grid>
    <DataGrid CanUserAddRows="True" AutoGenerateColumns="False" Height="2开发者_如何学编程00" HorizontalAlignment="Stretch" Margin="12,12,79,0" Name="dataGrid1" VerticalAlignment="Top" Width="389" DataContext="{Binding}" CanUserResizeColumns="False" CanUserResizeRows="False" HorizontalContentAlignment="Stretch" PreviewMouseDoubleClick="dataGrid1_PreviewMouseDoubleClick" CellEditEnding="dataGrid1_CellEditEnding">
        <DataGrid.Columns>
            <DataGridTextColumn Binding="{Binding  Path=UserID}"
                                Header="User ID" Width="SizeToHeader" />
            <DataGridTextColumn Binding="{Binding  Path=UserName}"
                                Header="User ID" Width="SizeToHeader" />
        </DataGrid.Columns>
    </DataGrid>
</Grid>

I would ideally like to access the data through doing something like rowData.UserID but I cannot seem to work it out. There are lots of tutorials and help for using DataGridView but I'm not using this.

UPDATED

To get the selected rows try:

IList rows = dg.SelectedItems;

You should then be able to get to the column value from a row item.

OR

DataRowView row = (DataRowView)dg.SelectedItems[0];

Then:

row["ColumnName"];

Solution based on Tonys answer:

        DataGrid dg = sender as DataGrid;
        User row = (User)dg.SelectedItems[0];
        Console.WriteLine(row.UserID);

I did something similar but I use binding to get the selected item :

<DataGrid Grid.Row="1" AutoGenerateColumns="False" Name="dataGrid"
          IsReadOnly="True" SelectionMode="Single"
          ItemsSource="{Binding ObservableContactList}" 
          SelectedItem="{Binding SelectedContact}">
  <DataGrid.Columns>
    <DataGridTextColumn Binding="{Binding Path=Name}" Header="Name"/>
    <DataGridTextColumn Binding="{Binding Path=FamilyName}" Header="FamilyName"/>
    <DataGridTextColumn Binding="{Binding Path=Age}" Header="Age"/>
    <DataGridTextColumn Binding="{Binding Path=Relation}" Header="Relation"/>
    <DataGridTextColumn Binding="{Binding Path=Phone.Display}" Header="Phone"/>
    <DataGridTextColumn Binding="{Binding Path=Address.Display}" Header="Addr"/>
    <DataGridTextColumn Binding="{Binding Path=Mail}" Header="E-mail"/>
  </DataGrid.Columns>
</DataGrid>

So I can access my SelectedContact.Name in my ViewModel.

DataGrid get selected rows' column values it can be access by below code. Here grid1 is name of Gride.

private void Edit_Click(object sender, RoutedEventArgs e)
{
    DataRowView rowview = grid1.SelectedItem as DataRowView;
    string id = rowview.Row[0].ToString();
}

I believe the reason there's no straightforward property to access the selected row of a WPF DataGrid is because a DataGrid's selection mode can be set to either the row-level or the cell-level. Therefore, the selection-related properties and events are all written against cell-level selection - you'll always have selected cells regardless of the grid's selection mode, but you aren't guaranteed to have a selected row.

I don't know precisely what you're trying to achieve by handling the CellEditEnding event, but to get the values of all selected cells when you select a row, take a look at handling the SelectedCellsChanged event, instead. Especially note the remarks in that article:

You can handle the SelectedCellsChanged event to be notified when the collection of selected cells is changed. If the selection includes full rows, the Selector.SelectionChanged event is also raised.

You can retrieve the AddedCells and RemovedCells from the SelectedCellsChangedEventArgs in the event handler.

Hope that helps put you on the right track. :)

After hours of finding ways on how to get the data from the row selected on a WPF DataGrid Control, as I was using MongoDB. I found this post and used Tony's answer. I revised the code to be relevant to my project. Maybe someone can use this to get an idea.

private void selectionChanged(object sender, SelectionChangedEventArgs e)
    {
        facultyData row = (facultyData)facultyDataGrid.SelectedItem;
        facultyID_Textbox.Text = row.facultyID;
        lastName_TextBox.Text = row.lastName;
        firstName_TextBox.Text = row.firstName;
        middleName_TextBox.Text = row.middleName;
        age_TextBox.Text = row.age.ToString();
    }

}

class facultyData
{
    public ObjectId _id { get; set; }
    public string facultyID { get; set; }
    public string acadYear { get; set; }
    public string program { get; set; }   
}

An easy way that works:

private void dataGrid_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e)
{
    foreach (var item in e.AddedCells)
    {
        var col = item.Column as DataGridColumn;
        var fc = col.GetCellContent(item.Item);

        if (fc is CheckBox)
        {
            Debug.WriteLine("Values" + (fc as CheckBox).IsChecked);
        }
        else if(fc is TextBlock)
        {
            Debug.WriteLine("Values" + (fc as TextBlock).Text);
        }
        //// Like this for all available types of cells
    }
}

I used a similar way to solve this problem using the animescm sugestion, indeed we can obtain the specific cells values from a group of selected cells using an auxiliar list:

private void dataGridCase_SelectionChanged(object sender, SelectedCellsChangedEventArgs e)
    {
        foreach (var item in e.AddedCells)
        {
            var col = item.Column as DataGridColumn;
            var fc = col.GetCellContent(item.Item);
            lstTxns.Items.Add((fc as TextBlock).Text);
        }
    }

If you are using an SQL query to populate your DataGrid you can do this :

Datagrid fill

Private Sub UserControl_Loaded(sender As Object, e As RoutedEventArgs)
        Dim cmd As SqlCommand
        Dim da As SqlDataAdapter
        Dim dt As DataTable

        cmd = New SqlCommand With {
            .CommandText = "SELECT * FROM temp_rech_dossier_route",
            .Connection = connSQLServer
        }
        da = New SqlDataAdapter(cmd)
        dt = New DataTable("RECH")
        da.Fill(dt)
        DataGridRech.ItemsSource = dt.DefaultView
End Sub

Value diplay

    Private Sub DataGridRech_SelectionChanged(sender As Object, e As SelectionChangedEventArgs) Handles DataGridRech.SelectionChanged
        Dim val As DataRowView
        val = CType(DataGridRech.SelectedItem, DataRowView)
        Console.WriteLine(val.Row.Item("num_dos"))
    End Sub

I know it's in VB.Net but it can be translated into C#. I put this solution here, it might be useful for someone.
