[Solved] Column width set to SizeToCells but don't resize

[Jean]

Hello,

I try to make the column width of the grid to follow the width of the bigger cell. So I've set the columnWitdh property to "SizeToCells". But it doesn't work.

I'm using the RadControls_for_Silverlight_4_2011_1_0419_Dev.

I've done a small application to show my problem : When I fill the cell witdh a large text the colunm width grow up, but when the text become smaller, the column width doesn't resize to become smaller too. 

MainPage.xaml :

<UserControl

    <Grid x:Name="LayoutRoot" Background="White" Height="300" VerticalAlignment="Top" HorizontalAlignment="Left" Width="400">

        <telerik:RadGridView x:Name="grid1"
                Margin="0,0,2,0" d:LayoutOverrides="Width" Height="157" VerticalAlignment="Top"
                ItemsSource="{Binding Data, ElementName=userControl, Mode=TwoWay}"
                ColumnWidth="SizeToCells"/>

        <Button x:Name="Button1" Content="Button Small Text" HorizontalAlignment="Left" Height="28" Margin="0,161,0,0" VerticalAlignment="Top" Width="145" Click="Button_Click"/>
        <Button x:Name="Button2" Content="Button Large Text" Height="28" Margin="149,161,115,0" VerticalAlignment="Top" RenderTransformOrigin="1.648,0.786" Click="Button2_Click"  />

            }
        }


        public MainPage()
        {
            InitializeComponent();
            Data.Add("a"); // a small text
        }

        private void Button_Click(object sender, System.Windows.RoutedEventArgs e)
        {
            Data.Clear();
            Data.Add("a"); // a Small text
            this.grid1.Rebind();
        }

        private void Button2_Click(object sender, System.Windows.RoutedEventArgs e)
        {
            // TODO: Add event handler implementation here.
            Data.Clear();
            Data.Add("eeeeeeeeeeeeeeeeeeeeeeeeeee"); // a Large text
            this.grid1.Rebind();
        }


    }
}

Thanks for your help!
