When a set of RadForms is used inside an MDI Form and are maximized, after some time, the child forms flicker continuously.

See the attached video.

The same behaviour DOES NOT happen when regular Windows Form is used.

I can not add any type of control to the layoutControlGroupItem.  I have a screen recording of me trying to follow the procedure shown but it is 60M so I can't attach it.  I shared the file on my OneDrive if you would like to access it that way.

Workaround
Either change the filter to StarrtsWith or remove the suggest functionality.

To reproduce: add a RadMap with a Bing provider, select the canvas "Aerial with labels on demand" and zoom in all the way. It always gets the following exception:

System.ArgumentException: Parameter is not valid.
   at System.Drawing.Image.FromStream(Stream stream, Boolean useEmbeddedColorManagement, Boolean validateImageData)
   at Telerik.WinControls.UI.MapTileDownloader.TileDownloadDataCompleted(Object sender, DownloadDataCompletedEventArgs e)
   at System.Net.WebClient.OnDownloadDataCompleted(DownloadDataCompletedEventArgs e)

The issue is reproducible in Demo application with the Bing examples.

Workaround:

        public RadForm1()

            bingProvider.UseSession = true;
            bingProvider.BingKey = "your bing key";
            LocalFileCacheProvider cache = new LocalFileCacheProvider(cacheFolder);
            bingProvider.CacheProvider = cache;
            this.radMap1.Providers.Add(bingProvider);
             
        }

        public class CustomMapTileDownloader : MapTileDownloader

It is difficult to replicate the issue and it is not always reproduced. When using the splitter between columns[1] and columns[2]  to resize column[1] I found out that releasing the mouse button doesn't cause the splitter to be released, even when clicking on the grid. It seems to work ok once or twice but once it fails then keeps failing.

Workaround:
        private void radVirtualGrid1_MouseUp(object sender, MouseEventArgs e)
        {
            if (e.Button == System.Windows.Forms.MouseButtons.Left)
            {
                this.radVirtualGrid1.Cursor = Cursors.Default;
            }
        }

Please refer to the attached if file. You will notice that the converter wizard will skip the designer file if the form's file end with "Settings".

Workaround: change the file name to skip ending with "Settings"

Hello,

I have downloaded the latest winform version today and launched my application.

I experienced an immediate crash while replacing a document container by a split container.

You can see the small piece of code and the insttruction which is causing the crash ....

Obviously it was working properly before upgrading ...

Can you help? I am now just stuck so a fix or a workaround would be useful...

Thanks,

Olivier D.

 

if (ctrlOutput == null)
            {
                Telerik.WinControls.UI.RadSplitContainer mainSplitContainer = null;

                ctrlOutput = new ToolWindowOutput(sbOutput);

                var Output = new Telerik.WinControls.UI.Docking.ToolWindow();
                Output.Text = "Output";
                Output.Controls.Add(ctrlOutput);

                var toolTabStrip = new Telerik.WinControls.UI.Docking.ToolTabStrip();
                toolTabStrip.Controls.Add(Output);

                if (this.documentContainer1.Parent == this.radDock1)
                {
