Hi,

I have an issue/query if you wouldn't mind help me out with please.

When using multiple monitors, if the main monitor is on scale and layout 100% and the 2nd monitor is 150%. When showing the context menu it blows the menu up even when shown on the main screen (see attached images).

Is there any way to disable Scale and Layout affecting the scale of the context menu or for the context menu to determine which screen it's being displayed on and use the Scale and Layout for that monitor?

Thanks.

Hi,

please see the attached sample and screen shot.

If application with Ribbon Bar is moved to a high dpi display (or started on a 4K display), two issues happen:

1. The title bar is not scaled (font) and has an ugly black line
2. The drop down element font is not scaled (the list itself is correct)

The problem, as described in the video, is that the thumb does not 'snap' to the point touched and then follow the touch as it is dragged. It is therefore difficult at times to actually 'grab' hold of the thumb unless you touch the screen in exactly the right point.

Changing the 'SnapToTicks' property purely makes the movement smoother once it is grabbed.

I created a simple project just with a dropdownlist. The data source of the dropdownlist is a reader from SQL. First time, when I type something in the text area of the dropdownlist, the autocomplete works perfectly: if a type "235", it brings me at the first job starting with '235' and I can select the job. After, when I click back in the text area to type something else (for example: "236"), I can just type '2'. It won't let me type anything else and the autocomplete is not working. The autocomplete mode is Suggest.

This is a new problem with telerik 2020.2.512.40. Just previously, I had the trial version (2020.1.218.40) and it was working without problem. I didn't change anything in the small project. In fact, I took this project and put Telerik.Wincontrols.UI version 2020.1.218.40 anf it was working properly. I put back the version 2020.2.512.40 of the control and the problem reappeared.

First time (works fine):

Seconf time: not able to type more than 1 character

I have a radGridView with a radContextmenu attached. When I open the radContextmenu via right clicking a form and then move the mouse scroll wheel radContextmenu is closed and the form behind the radContextmenu begins to scrolls. This does not happen with the standard contextMenu. 

I would like to avoid the mouse scroll wheel from closing the radContextmenu. The reason is in some radContextMenus I embed forms with scroll bars and so would like the user to use the mouse wheel to scroll these embedded forms (I can confirm that the scroll bars on these forms work fine while embedded in the context menu) rather than close the radContextmenu.

Please run the sample project on 100% and 150% DPI scaling. You will notice that with 100% the shown form is centered to its parent, but with 150% it is shifted:

Please use the following code snippet and click the filter button for the first column in the virtual grid. You will notice that the default menu is shown:

        RadContextMenu menu = new RadContextMenu();
        public RadForm1()
        {
            InitializeComponent();
            RadDateTimePicker aDateTimePicker = new RadDateTimePicker();
            RadMenuItem theMenuItem = new RadMenuItem();
            theMenuItem.MinSize = new Size(200, 30);
            RadHostItem theHostItem = new RadHostItem(aDateTimePicker);
            theMenuItem.Children.Add(theHostItem); 
            menu.Items.Add(theMenuItem);
            this.radVirtualGrid1.RowCount = 50;
            this.radVirtualGrid1.ColumnCount = 5;
            this.radVirtualGrid1.CellValueNeeded+=radVirtualGrid1_CellValueNeeded;

            this.radVirtualGrid1.AllowFiltering = true;
            this.radVirtualGrid1.ContextMenuOpening+=radVirtualGrid1_ContextMenuOpening;
        }

        private void radVirtualGrid1_ContextMenuOpening(object sender, VirtualGridContextMenuOpeningEventArgs e)
        {
            int i;
            string theMenuItemText;

            if (e.RowIndex == -3 && e.ColumnIndex < 1)
            {
                e.ContextMenu = menu.DropDown; 
            }
        }

        private void radVirtualGrid1_CellValueNeeded(object sender, VirtualGridCellValueNeededEventArgs e)
        {
            e.Value = Guid.NewGuid().ToString();
        }

Hi,

I am working on making our Winforms UI projects DPI aware to clean up fuzzy text in Windows 10.

I'm having an odd issue with some layouts. In one example, we have a simple form dialog that will grow with a label inside (similar to a windows message box). THe label is autosizing itself and has a minimum and maximum size set. This dialog is working fine without the DPI awareness, however, after enabling, the RadForm resizes to some strange size. I tried to investigate and it seems that the label is resizing to some large size and not respecting it's maximums (though this doesn't show when rendering as I've switched off the borders).

The label is resizing the form via anchors. I think probably there is a better way at layout here, but I'm wondering if the wild resizing may be considered a bug.

See images below.

I've also attached a project that reproduces this issue.

Hello.

In my application, depending on the specific data in the grid I may want to warn a user who clicks on the header checkbox that changing all the values in that column may not be what he intends, allowing him to cancel out of the operation.  I haven't found a handler that gets called when clicking on the header checkbox that allows me to cancel the event.  How can I accomplish this?

Hello

In RadCheckedDropDownList, We are using 'TelerikMetroBlue' theme. When we select multiple items in dropdownlist, its creating issue in rendering items in TextBlock. Selected items are coming on top of DropDownListElement ArrowButton, I can't see arrow button clearly due to items in background. If i use another theme then its working fine but i have to use 'TelerikMetroBlue' theme. please find attached.

Please advise.

Using the spellchecker, and the popup when using themes overlaps as per image below. If i make : 

        e.SpellingForm.Controls("buttonIgnoreAll").Visible = False

Hi,

I have menu problem:

When the Backstage Button Item is clicked and you don't release a left mouse button click but instead mouse is dragged to the right of the form, Backstage Button Item stay selected and can only be returned to default state if you click on it again else its stays blue and locked.

Picture 1.

Left click, hold and drag to the right. This state can be done to all buttons see Picture 2. Focus on "MouseDown" Event is not working.

Picture 2.

My question is can this behavior be prevented ?

Thanks in advance !

Hello,

I am using the WebCam Control in WinForms (latest Version) and placed it on an empty form. Then I tested this "program" on a Test device (CAT T20 Win10 Tablet). The preview picture in the control does not match the orientation of the device. (depending on which side of the device is at top the visible picture is rotated 90/180 degrees).

For testing purposes I installed the WinForms Example application on the same tablet device with the same results.

How to sync the captured picture to the orientation of the device? In the WPF documentation of the WebCamControl I found a Videoflip method, which is not available in WinForms.

Best regards,

Stefan
