I am working with the RadListView and noticed that its right and bottom border gets clipped at some (not all) width/heights and some scale factors (most notably 150% and 175%). This problem does not occur with the basic System.Windows.Forms.ListView.

Here is the code that I have wrote to replicate this problem with both the WinForms list view and the RadListView. 

      private void InitializeComponent()
      {
              this.listView1 = new System.Windows.Forms.ListView();
              this.radListView1 = new Telerik.WinControls.UI.RadListView();
              ((System.ComponentModel.ISupportInitialize)(this)).BeginInit();
              this.SuspendLayout();

              this.listView1.HideSelection = false;
              this.listView1.Location = new System.Drawing.Point(155, 10);
              this.listView1.Name = "listView1";
              this.listView1.Size = new System.Drawing.Size(135, 175);

              this.radListView1.Location = new System.Drawing.Point(5, 10);
              this.radListView1.Name = "radListView1";
              this.radListView1.Size = new System.Drawing.Size(135, 175);
              this.radListView1.UseCompatibleTextRendering = true;

              this.Controls.Add(this.radListView1);
this.Controls.Add(this.listView1);

              this.Name = "RadForm1";
              this.Text = "RadForm1";
              ((System.ComponentModel.ISupportInitialize)(this)).EndInit();
              this.ResumeLayout(false);
      }

Here is a screenshot of the dialog when the scale factor is at 100% (left is the RadListView component):

and here is a screenshot of when my display is scaled at 150% (left is the RadListView component):


To replicate: run the project attached, both at 100% scaling and 150% scaling. 

Thanks!

When navigating to the second page of the attached pdf document, the textbox field becomes non-editable. However, when the same document is opened in Adobe Acrobat, editing works as expected.

Hi,

 

When using a RadDropDownList component and the RadVirtualKeyboard component I have a problem. The AutoCompleteMode.Suggest works fine the first time I click on RadVirtualKeyboard but for the other clics the suggested items don't appears on the screen.

 

Regards

   Gilles

On touch devices, when pressing a key, it remains stuck and repeats. This is observed in Windows 11.

Contrary to Telerik.WinControls.UI.Barcode.QRCode, Telerik.WinControls.UI.Barcode.Symbology.QRCode creates invalid (unscannable) QR-Codes if the message contains umlauts when using ECIMode.UTF8.

 

We are using Symbology.QRCode, because we use it in columns of a RadGridView.

I've attached two example QR-Codes of the value "Bär", one using Barcode.QRCode, and the other one using Barcode.Symbology.QRCode.

Note: I have one scanner that can scan some of the Barcode.Symbology QR-Codes with umlauts.

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.

Currently, colors with an alpha channel defined with the 'rgba' function are not respected, for example, the following:

<span style="background-color: rgba(0, 0, 0, 0.5);">Some text</span>

It is imported as black color; semi-transparent colors are exported without the alpha channel.

In this scenario, the drag-drop a RadButton into the form designer. Then we set the Windows 11 Dark theme to be the default theme of the application. If we don't change the size of the button and run the application, the button is not visible.

In the current scenario, we are using RadOpenFileDialog. When trying to select 700 items in the UI using Ctrl + A, the control freeze due to the large number of files.

Hi Guys,

 

ColorDialog on higher dpi has some small problems.

1. Size of dialog is larger so there is large gap in right and bottom part.

2. Selected radio button black circle is not in center of larger circle.

 

Best regards

Rene
