Syntax highlighting editor that supports C# and intelisense

The exception bubbles up to the ViewFactory.ShowWebCam() method, but it doesn't get trapped by that method's try/catch or in your OnWebCamError event.

To reproduce (a bit random)

Im using a logitech HD C270, usb cam

There's often a period of initialization where the cam shows a white or black screen. Sometimes, pressing the control's capture button during this period causes the exception.

I reproduced it in the telerik Quick Start Framework, web cam app. The following code window is the stack trace of when it happened.

I understand that this is within Media Foundation code, and I'm guessing the capture is asynchronous, but is there any way that your control can catch the error as I know my users will be onto the support department when it happens?

Or is there any way to disable your embedded buttons until an image actually appears? I've tried trapping some paint events within the control but failed.

There's also no indication of what's happening during the initialization period, which has taken 10-20 secs occasionally, so it's very tempting to press those buttons :)

The tab order in the dialog is incorrect, the dialog is not focused when shown.

Workaround: 

Using FirstLook (also in my application) run the WebCam sample.

Press the takePhotoButton while running youtube video on 2nd monitor (also with netflix, so I assume it's general)

Sound on video pauses and returns when webcam control closed down.

Might be bug, or driver (Im using usb headphones) or needs me to set some property?

To reproduce:

- drop a track bar and make it less than 100 pixels, move the thumb to the right. 

Workaround:

 rtbPlaybackSpeed.TrackBarElement.MinSize = new System.Drawing.Size(0, 0);

Please refer to the following code snippet demonstrating how the comparer can be applied:

        public RadForm1()
        {
            InitializeComponent();
            this.radGridView1.EnableFiltering = true;
            this.radGridView1.ShowHeaderCellButtons = true;
            this.radGridView1.FilterPopupInitialized += radGridView1_FilterPopupInitialized; 
        }

        private void radGridView1_FilterPopupRequired(object sender, FilterPopupRequiredEventArgs e)
        {
            RadListFilterPopup popup = e.FilterPopup as RadListFilterPopup;
            if (popup != null)
            { 
                popup.MenuTreeElement.TreeView.TreeViewElement.Comparer = new MyComparer(popup.MenuTreeElement.TreeView.TreeViewElement);
            }
        }

        class MyComparer : TreeNodeComparer
        {
            public MyComparer(RadTreeViewElement treeView)
                : base(treeView)
            {
            }
            public override int Compare(RadTreeNode x, RadTreeNode y)
            {
                if (this.TreeViewElement.SortOrder == SortOrder.Descending)
                {
                    return x.Text.CompareTo(y.Text);
                }
                return x.Text.CompareTo(y.Text) * -1;
            }
        }

Hi Team,

Are there any intermediate zoomlevel in the RadMap object?

Currently the transition from one zoomlevel to another is too important.
Thank you for your response

Add a RadSpreadsheet on the form and try resizing it at design time. You will notice that the control is resized after a considerable delay.

If you Dock the control to Fill and try resizing the form at run you will notice that the layout is incorrect. The attached gif file illustrates the obtained behavior.

Workaround: update the layout after resizing:

I am currently working in Telerik v2019.3.917 and .Net 4.5.2. I have multiple theme's setup for a local application for my users but I am seeing something odd with the Telerik.WinControls.Themes.HighContrastBlack theme. It appears that I am unable to select more than one cell in this theme. My grid has multiselect as true and SelectionMode as CellSelect. I have tried holding ctrl and clicking cells, clicking the row header, holding the mouse down and dragging, and using Ctrl+A but none of these select more than one cell.

I am setting the application theme on launch:

Themes that work: All Fluents, All Material, All VS.

Is this a bug or am I missing something?

Please run the attached sample project with the latest version. You will notice that the maximized floating window is not loaded properly. This used to work in versions prior to R1 2019.

Workaround: remove "WindowState=Maximized" from the XML.

Please refer to the attached sample project and follow the steps from the gif file. 

You will notice that each time a random group displays only images (no text) when the groups don't fit in the ribbon's width.

Workaround:

        public MDIForm()
        {
            InitializeComponent();
            this.radRibbonBar1.RibbonBarElement.ItemVisiblityStateChanging += this.RibbonBarElement_ItemVisiblityStateChanging;
        }

        private void RibbonBarElement_ItemVisiblityStateChanging(object sender, ItemVisiblityStateChangingEventArgs args)
        {
            if (args.NextVisibilityState == ChunkVisibilityState.NoText)
            {
                args.Cancel = true;
            }
        }

If you currently install the nuget package "UI.for.WinForms.Themes", all themes are loaded and referenced. If you only use one theme in the application, you have to remove all others manually. It would be nice if there was an extra package for each theme.

I know it is not an easy task.

I love the new vb.net form conversion to telerik form .

Could you please make one from vb6 to telerik form conversion. I know I am asking for a lot but I am pretty sure your sales is going to skyrocket with this feature.

Please think about it.

To reproduce:
- Open attached project and add a lot of pages. 
- Close all pages 
- The GDI object count increases. 

Workaround:
GC.Collect();
GC.WaitForPendingFinalizers();
GC.WaitForFullGCApproach();
GC.WaitForFullGCComplete();
GC.Collect();

Use attached to reproduce.

Workaround:
Set the TableHeaderHeight again after loading the layout. 

Hi Progress Team,

I have encountered another issue in the RadPopupEditor control. For RadSpinEditor controls as well as for RadTextBox controls on the Popup container form, no value changed or validating/validation events are fired. For RadSpinEditor controls the ValueChanged event is fired when the spin buttons are used to change the value but when the user directly enters a value in the editor element and the control losts the focus (either by TAB or mouse click outside the control) the ValueChanged event is missing.

I have attached a small VS2017 project which illustrates the issue.

Thank you very much!

Regards,

Jürgen

Please refer to the attached sample project and follow the steps illustrated in the gif file.

Note: if the vertical  scrollbar is visible, the editor is activated as expected. 

Workaround:

Me.RadListView1.ItemSize = New Size(200, 30)
