When you set a RadGridView's SelectionMode to GridViewSelectionMode.CellSelect and then you highlight full rows by using the row header, the SelectedRows collection is empty.  Telerik support informed me this is "as expected" and that I should use "SelectedCells" collection when using the CellSelect Mode.  While this is a decent workaround I don't see why SelectedRows collection can't be filled when the entire row is actually highlighted.

Hi

When using group view we need the reminders to be shown for a selected (set programitically) resource. At the moment it shows reminders for all resources that have appointments that need reminding. In our case we have users who have scheduler open in group view showing multiple resources but would only like to be reminded about appointments that are for the user using the system.

To reproduce:

1.Add some text to RadRichTextEditor.
2.Copy an image from a Word document and paste it to the RadRichTextEditor.
3.Export the document content with RtfFormatProvider.

When you try to open the exported .rtf file via WordPad, you will notice that the image is not loaded. Please refer to the attached files created by MS Word and RadRichTextEditor.

To reproduce: please refer to the attached sample project. Note that the CellValidating event is fired twice even without showing a RadMessageBox. With an MS Button the problem is not reproducible.

Workaround: use the RadGridView.ValueChanging event to perform validation while the user is typing in the active editor:
 private void radGridView1_ValueChanging(object sender, Telerik.WinControls.UI.ValueChangingEventArgs e)
 {
   if (((string)e.NewValue) != "x")
     {
         RadMessageBox.Show("Only 'x' allowed!");
         e.Cancel = true;
     }
 }

To reproduce:
- Set the font of the tool window:
  ((ToolTabStrip)this.toolWindow1.TabStrip).CaptionElement.Font = font1;
- Make the tool window floating and then dock it again.
- The font is not preserved.

Workaround:
Set the font in the DockStateChanged event.

I have a GridView (Winforms v. 2017.3.1017.40, same problem with 2017.2.502.40) configured as on the attached screenshot (made some groups, made a search, and used the "excel-like" filter on a column to uncheck some values).

Then I try to click on some column headers to sort the grid.
After a few clicks, I get this error :
InvalidOperationException: La collection a été modifiée ; l'opération d'énumération peut ne pas s'exécuter.

I got different stacktrace with the same error :
InvalidOperationException: La collection a été modifiée ; l'opération d'énumération peut ne pas s'exécuter.

Use attached to reproduce.

Workaround:

- Use RadForm it explicitly handles the controls scaling. 
- Make sure that the following of the user controls are set like this:

this.AutoScaleDimensions = new System.Drawing.SizeF(96F, 96F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi;

To reproduce: run the attached sample project and follow the steps in the gif file.
When you start dragging, (i.e. when MouseMove first fires) there is a large jump to the position of the image.

To reproduce: add some nodes to the tree view at design time

        public RadForm1()
        {
            InitializeComponent();

            this.radTreeView1.AllowDragDrop = true;
            this.radTreeView1.DragEnding += radTreeView1_DragEnding;
        }
        
        private void radTreeView1_DragEnding(object sender, Telerik.WinControls.UI.RadTreeViewDragCancelEventArgs e)
        {
            if (MessageBox.Show("Are you sure you want to move?", "Question", MessageBoxButtons.YesNo) == System.Windows.Forms.DialogResult.No)
            {
                e.Cancel = true;
            }
        }

Then try to drag and drop a node. You will notice that the application hangs

Workaround: use RadMessageBox

At the moment when the control receives the focus the text gets selected. if the AllowShowFocusCues property is set to true and the DropDownStyle is set to DropDownList the focus cues should be painted similarly as in RadDropDownList
this.radMultiColumnComboBox1.AllowShowFocusCues = true;
this.radMultiColumnComboBox1.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;
