RadListView: Missing Borders when scaled at 150% and higher

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!

Thanks Nadya! That worked. I can now display all four borders for the RadListView with a higher DPI. Much appreciated!

Hello, Joseph,

Upon check the status of this feedback item, it is still not completed.

However, I managed to find a workaround which might do the job for you until we introduce a regular fix. You can set the BorderBoxStyle to FourBorders as follows:

 this.radListView1.ListViewElement.BorderBoxStyle = BorderBoxStyle.FourBorders;

With this, all four borders are shown in RadListView even on 150% dpi scaling. Can you give this a try and let me know if it works for you.

Hello, Gemma,

Thank you for reporting this behavior. I am also able to reproduce this with RadListView on 150% and 175% dpi. On 100% and even 125% the issue does not happen on my end.

I approved this bug report on our feedback portal. And also granted you Telerik Points for bringing it to our attention.
