Hi,

 Since UI WPF Q3 2015, I notice change in the GridView column auto size. I have the following simple user control (with no height and width) :

 

<UserControl x:Class="WpfApplication1.UserControl1"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:local="clr-namespace:WpfApplication1"
             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
             mc:Ignorable="d"
             d:DesignHeight="300" d:DesignWidth="300">
    <Grid>
        <telerik:RadGridView AutoGenerateColumns="False">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="Name" Width="150"/>
                <telerik:GridViewDataColumn Header="Description" Width="*"/>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
    </Grid>
</UserControl>

In my MainWindow I have a button which show a RadWindow with the UserControl content :

private void OnClick(object sender, RoutedEventArgs e)
{
    RadWindow window = new RadWindow();
    window.SizeToContent = true;
    window.Content = new UserControl1();
    window.SizeChanged += delegate
    {
        window.Header = string.Format("({0}, {1})", window.Height, window.Width);
    };
    window.ShowDialog();
}

In Telerik 2015.2.728.45, the RadWindow size is correct (like i expect in fact). In Telerik 2015.3.* the gridcolumn with Width="*" take all width possible (infinite?) and radwindow Width become infinite.

 

What's the correct behavior ? Telerik 2015.2 or 2015.3 ? Do I need to set the UserControl size ? (I prefer to avoid this solution like my real application is more complex and expect to have an UserControl resize from its content).

Thanks

Regards

Luc

Hi Stefan,

For your information, windows are width over-sized not only for GridView. I have the same behaviour with RadRichTextBox for sample.

Any clues ?

Hi Luc,

Thank you for the additional information and please excuse me for the delayed reply.

After investigating the issue, it seems that there has been a malfunction of the SizeToContent property of RadWindow as of 2015.2. With 2015.3 version it has been fixed, so the expected behavior in a scenario as yours would be the control to take all width possible.
