DataGrid 中的 C# WPF Select 在文本框中按 Enter 的第一行

Question

I have a TextBox (SearchBox - TabIndex=0) and a populated DataGrid TabIndex=1. I want after input of the keyword in the SearchBox by pressing Enter to select the first row in the DataGrid.

So far i have just this:

  private void txtSearchBox_KeyDown(object sender, System.Windows.Input.KeyEventArgs e)
    {
        if (e.Key == System.Windows.Input.Key.Enter)
        {
            System.Windows.Controls.TextBox txtb = sender as System.Windows.Controls.TextBox;
            txtb.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
        }
    }

It selects the whole DataGrid and not the row.

Thank you for your help.

EDIT: I´ve added this to code above and the problem was solved:-)

dataGrid.SelectedItem = dataGrid.Items[0];

Answer 1

I´ve added the following code to the Searchbox_KeyDown

dataGrid.SelectedItem = dataGrid.Items[0];

And this solved my problem!
