[Solved] Auto generated columns reordering when not visible

[Cantenot Frederic]

Hello,

With a RadGridView, in Q3 release, I'm using auto generated columns feature.
When user is reordering columns, they seem disturbed when some of them are not visible.

The code sample below allow you to build a grid and after hiding the first column, when you try to reorder columns, you'll get similar result as the picture attached.

<UserControl x:Class="TestGridViewColumn.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="400">

    <Grid x:Name="LayoutRoot" Background="White">
        <Grid.RowDefinitions>
            <RowDefinition Height="20" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>

        <StackPanel Orientation="Horizontal" Grid.Row="0" >
            <CheckBox Content="SampleText" IsChecked="True" Checked="CheckBox_Checked" Unchecked="CheckBox_Checked" />
            <CheckBox Content="SampleTitle" IsChecked="True" Checked="CheckBox_Checked" Unchecked="CheckBox_Checked" />
        </StackPanel>

        <telerik:RadGridView AutoGenerateColumns="True" x:Name="RadGridView_Sample" IsReadOnly="True" Grid.Row="1" />
    </Grid>
</UserControl>

namespace TestGridViewColumn
{
    public class SampleClass
    {
        public string SampleTitle { get; set; }
        public string SampleText { get; set; }
        public decimal SamplePrice { get; set; }
        public decimal SampleTaxes { get; set; }
        public DateTime SampleDate { get; set; }
    }

    public partial class MainPage : UserControl
    {
        private bool _Initialized = false;

        public MainPage()
        {
            InitializeComponent();
            _Initialized = true;

            List<SampleClass> lst = new List<SampleClass>();
            lst.Add(new SampleClass() { SampleText = "Sample 1" });

            RadGridView_Sample.ItemsSource = lst;

        }

        private void CheckBox_Checked(object sender, RoutedEventArgs e)
        {
            if(_Initialized)
            {
                CheckBox chk = (sender as CheckBox);
                RadGridView_Sample.Columns[chk.Content.ToString()].IsVisible = chk.IsChecked.Value;
            }
        }
    }
}

Hi Cantenot Frederic,

We did have similar issues, but they have already been fixed. So, I would recommend you to try your application with our current official release Q1 2011 SP1. 
Please let me know whether you still continue to experience the same behavior.

All the best,
