Get data from DataGrid WPF

How can I get data from DataGrid when ComboBox' text is equal with the record of the DataGrid:

combobox1.ItemsSource = database.Mahs.ToList();

combobox1.DisplayMemberPath = "MahName";

and

private void datagrid_customer_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    var data = datagrid_customer.SelectedItem;
    string id = (datagrid_customer.SelectedCells[0].Column.GetCellContent(data) as TextBlock).Text;
    txt_f1.Text = id;
}

It shows me the id, but when i selected item but i want show me id when combobox.Text = name of the row in the DataGrid, then show the id of that row.

I would suggest changing your approach slightly, and retrieving the entire object from both controls for the comparison. This way you have full access to the properties of each selected object.

If the objects you're retrieving from your database override .Equals and .GetHashCode you could do away with some of the if statements below. But to get you started here's a quick example of your change listener

private void datagrid_customer_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    // Cast the objects from your DataGrid and your ComboBox. 
    YourDataObject dataItem = (YourDataObject)dataGrid1.SelectedItem;
    YourDataObject comboItem = (YourDataObject)combo.SelectedItem;

    // Compare your objects and decide if they're the same. Ideally you would 
    // have Equals and HashCode overridden so you could improve this
    if (dataItem == null || comboItem == null)
        text.Text = "Not Matching";
    else
    {
        if (dataItem.MahName == comboItem.MahName)
            // You've got full access to the object and all it's properties
            text.Text = dataItem.Id.ToString();
        else
            text.Text = "Not Matching";
    }
}
