Groupbox remain in render

Hello,

I have a very simple form that has this code:

 

public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
    public RadForm1()
    {
        InitializeComponent();
 
        ThemeResolutionService.ApplicationThemeName = "Fluent";
    }
 
    private void radButton1_Click(object sender, EventArgs e)
    {
        SetStartForm(false);
    }
 
    private void SetStartForm(bool visible)
    {
        this.radGroupBox1.Visible = visible;
    }
 
    private void radButton2_Click(object sender, EventArgs e)
    {
        SetStartForm(true);
    }
}

 

At the start it call the SetStartForm() method that with a lot of other things hide the groupbox.

Well after a search when a user click again the button "Nuova Ricerca" I call again SetStartForm() but the components rendering remain with the border. Please see the video:

How can I solve that? Thanks

Hello Dess,

Hi, Gianluca,

Since it is very important for us to avoid sharing sensitive information in the public portal, the video link has been deleted. There is a gif file in my initial reply which simulates an identical scenario.

If you need any other modification, please let me know.

Hello Dess,

thanks for the Telerik points and for put this issue inside your Feedback portal. Thanks also for the workaround you suggested to me. Anyway please change the text of my ticket and the url of my own space to something that do not address to my personal project because now it's public for everyone.

 

Thanks

Hello, Gianluca,      

The provided sample video and code snippet are greatly appreciated. I was able to simplify the scenario and replicated the issue on my end. I have logged it in our feedback portal by making this thread public. You can track its progress, subscribe for status changes and add your comments on the following link -  https://feedback.telerik.com/winforms/1384809-groupbox-remain-in-render

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to invalidate the form after hiding the RadGroupBox

this.FormElement.InvalidateMeasure(true);

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
