Use the attached project to reproduce:

- Click the first button so the image is changed

- Click the second button and examine the exported HTML

Expected: the Uri is exported

Actual: the Uri is not exported.

Workaround: 

p.Inlines.AddAfter(image, image2);
p.Inlines.Remove(image);

To reproduce this:

  1. Use the .NET Core version of the Telerik dlls.
  2. Set the GroupRenderMode of RadGridView to Flat.
  3. Page RadGridView using RadDataPager.
  4. Scroll to the last row in the view. Or scroll to any row so that few of the rows above are not longer visible.
  5. Expand the row details and scroll down more until only the parent row is visible.
  6. Collapse the row details. At this point, the vertical scrollbar disappears and the upper rows are not brought into the view as expected when the row details gets collapsed.

To work this around call the Rebind() method of RadGridView on RowDetailsVisibilityChanged event.

private void RadGridView_RowDetailsVisibilityChanged(object sender, Telerik.Windows.Controls.GridView.GridViewRowDetailsEventArgs e)
{
	if (e.Visibility == Visibility.Collapsed)
	{
		this.gridView.Rebind();
	}        
}

As a Followup to this (Bad performance with grouping)Forumpost I managed to reproduce the issue now.
Since i cannot upload zip-files in the Forum I am doing it here.


The problem is, that a single grouping dramatically increases the time for sorting the values.
When the grouping is not present, sorting the same column is much faster.


It appears that it is related to the ammount of columns in total (not grouped).
The ammount of records is not so important, 100 (as in the attached sample) should not be significant.

In some cases the string values in the XML attributes are not colored with the expected color, but default to black.
 
This was reproduced when there is only single quotation mark on visible on the line. And also if the count of the visible quotation marks on the line is an odd number (not always reproducible).

The document styles are not respected because of wrongly imported custom style name after copy-paste from MS Word and exported to HTML.

Workaround: avoid using styles with braces in their name.

The used cell range is expanded when styles to all columns are applied and one copies an entire row.

Workaround:

private void RadSpreadsheet_WorkbookChanged(object sender, EventArgs e)
{
    var range = this.radSpreadsheet.Workbook.ActiveWorksheet.UsedCellRange;
    this.radSpreadsheet.ActiveWorksheet.Columns[range.ColumnCount + 1, SpreadsheetDefaultValues.ColumnCount - 1].Clear(ClearType.All);
}

To reproduce:

- Select several words by holding the control key. 

- Paste some text. 

Result: the first word is replaced, the other are deleted

Expected: the text should be pasted in all selected places

Workaround:

private void RadRichTextBox_CommandExecuting(object sender, Telerik.Windows.Documents.RichTextBoxCommands.CommandExecutingEventArgs e)
{
    if (e.Command is PasteCommand)
    {
        var ranges = radRichTextBox.Document.Selection.Ranges.ToList();
        if (ranges.Count > 1)
        {
            e.Cancel = true;

            foreach (var range in ranges)
            {
                radRichTextBox.Document.Selection.Clear();
                radRichTextBox.Document.Selection.AddSelectionStart(range.StartPosition);
                radRichTextBox.Document.Selection.AddSelectionEnd(range.EndPosition);
                PasteNewText();
            }      
        }
    }
}
public void PasteNewText()
{
    DocumentFragment clipboardDocument = null;
    string clipboardText = null;
    bool clipboardContainsData = false;

    if (ClipboardEx.ContainsText(null))
    {
        clipboardText = ClipboardEx.GetText(null);
        clipboardContainsData = true;
    }

    if (!clipboardContainsData)
    {
        return;
    }

    if (clipboardDocument != null)
    {
        this.radRichTextBox.ActiveDocumentEditor.InsertFragment(clipboardDocument);
    }
    else if (!string.IsNullOrEmpty(clipboardText))
    {
        this.radRichTextBox.ActiveDocumentEditor.Insert(clipboardText);
    }
}

We noticed that RadGridView does not get garbagecollected sometimes.
So i fired up  a memory analyzer to see what is going on.

This is the graph that shows that the RadGridView is causing a leak. The only references that keep the GridView from getting collected are those two WeakEventListeners

To further investigate i decompiled GridViewDataControl and could identify the culprit.

private void SubscribeToDispatcherShutdown()
    {
      if (this.dispatcherShutdownListener != null)
        this.dispatcherShutdownListener.Detach();
      this.dispatcherShutdownListener = new WeakEventListener<GridViewDataControl, object, EventArgs>(this);
      this.dispatcherShutdownListener.OnEventAction = (Action<GridViewDataControl, object, EventArgs>) ((grid, source, eventArgs) => grid.OnDispatcherShutdownFinished(source, eventArgs));
      this.dispatcherShutdownListener.OnDetachAction = (Action<WeakEventListener<GridViewDataControl, object, EventArgs>>) (weakEventListener => this.Dispatcher.ShutdownFinished -= new EventHandler(this.dispatcherShutdownListener.OnEvent));
      this.Dispatcher.ShutdownFinished += new EventHandler(this.dispatcherShutdownListener.OnEvent);
    }

In the second line from the botton

... weakEventListener => this.Dispatcher.ShutdownFinished -
... you are using 'this.Dispatcher...' which causes the leak since the Action will implicitly capture the 'this' reference.
Which kind of defeats the prupose of having a WeakReference inside your WeakEventListener.

Sadly i cannot figure out how it happens, but i think its only when Detach (FrameworkElement.Unloaded ultimately) is not called.
While this is the actual issue, i thought I'd share this with you so you.
