Hello,

I tried to use the DisplayAttribute on my properties to make GridView automatically generate columns.
The columns are displayed but the attribute "Order" seems to get ignored:


[
[Display(ResourceType = typeof(Loc), Name = "LTitle", Description = "LTitleDescription", Order = 0)] 
public string Title {getset; } 
Display(ResourceType = 
typeof(Loc), Name = "LFirstName", Description = "LFirstNameDescription", Order = 1)] 
public string FirstName { getset; } 

The colums are displayed, but in the wrong order.

Hello,

I see there are some changes in changelog for Q1 2010 that suggest you've added support for "Order" attribute. However in my very simple solution it still doesn't work. Can you confirm that column ordering is supported in the newest build of your silverlight controls?

Here is a part of my solution:

Person.cs
using System; 
using System.Net; 
using System.Windows; 
using System.ComponentModel.DataAnnotations; 
 
namespace SilverlightApplication1 
    public class Person 
    { 
        [Display(Name="FName", Order=10, ShortName="test name")] 
        public string FirstName { getset; } 
 
        [Display(Name = "Last Name", Order = 1)] 
        public string LastName { getset; } 
 
        [Display(Order = 11)] 
        public int Age { getset; } 
 
        [Display(Order = 111)] 
        public DateTime DateOfBirth { getset; } 
 
        [Display(Order = 2)] 
        public bool Married { getset; } 
    } 
 
 

MainPage.xaml.cs
using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Net; 
using System.Windows; 
using System.Windows.Controls; 
using System.Windows.Documents; 
using System.Windows.Input; 
using System.Windows.Media; 
using System.Windows.Media.Animation; 
using System.Windows.Shapes; 
 
namespace SilverlightApplication1 
    public partial class MainPage : UserControl 
    { 
        public MainPage() 
        { 
            InitializeComponent(); 
 
            List<Person> persons = new List<Person>(); 
            for (int i = 0; i < 100; i++) 
            { 
                persons.Add(new Person() 
                { 
                    FirstName = "John"
                    LastName = "Smith " + (i % 10), 
                    Age = i, 
                    DateOfBirth = new DateTime(2010, 5, (i % 10) + 1), 
                    Married = (i % 2 == 1) 
                }); 
            } 
 
            telerikGrid.ItemsSource = persons; 
        } 
    } 
 

MainPage.xaml
<UserControl x:Class="SilverlightApplication1.MainPage" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" 
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
    mc:Ignorable="d" 
    d:DesignHeight="300" d:DesignWidth="400"
 
    <Grid x:Name="LayoutRoot" Background="White"
        <telerik:RadGridView Name="telerikGrid" AutoGenerateColumns="True"/> 
    </Grid> 
</UserControl>

Marcin

Hi Kowal,

Since Q1 2010 SP1 we have added order attribute support. I have prepared sample application demonstrating it using the posted snippets.

If you have any other questions or issues do not hesitate to contact us.

Hello,

Thank you for your quick reply.
However, using the newest trial build of SL controls (2010.1.422.1040), columns are not being reordered according to Order attribute. Your example solution has references to  v2010.1.422.1030 of SL controls and it seems to work OK. Maybe this is the reason of my problems?

Greetings
Marcin

Hi Kowal,

It seems that the problem indeed appears in this version. If you can, please use the 2010.1.422.1030 version, otherwise I can suggest to use our next internal built (available later today).

Please, excuse us for the inconvenience caused.

Hello,

I have the save ordering problem with the latest release built 2010.1.422.1040 for the radgridview.
I see you have mentioned it being solved by your internal build, which version would that be? and when do you
anticipate this issue to be addressed or solved soon.
