When the user makes the pinch gesture the expected behavior would be for the zoomed point to be the touch position, but it is instead the top left corner of the page.

WPF allows running multiple UI threads in a single process. When RadPdfViewer is used in such scenarios, sometimes InvalidOperationException: 'The calling thread cannot access this object because a different thread owns it.' is thrown. 

- Show Find dialog (or any other of the dialogs available for register in ExtensibilityManager class) for the first instance, the for the second instance.

When the user copy-pastes an image from Outlook, it is pasted as an IncludePictureField and visualized as expected. The field code looks like


However, when the fields in the document are updated, the image is no longer shown because of its invalid Uri. In MS Word, when you paste the image, it is directly inserted as image and the field is skipped.

Workaround - remove the field start/ends (in the attachments)

After merging a document into another one (or pasting it), some of the content is duplicated. The issue is a regression in R3 2018.

This happens  whether there is available space in the active area are not. All items are rendered in the minimized area.

To work this around you can set the IsContentPreserved property after the control is loaded.
private void FavouritesBar_Loaded(object sender, RoutedEventArgs e)
    Dispatcher.BeginInvoke(new Action(() =>
        this.FavouritesBar.IsContentPreserved = true;
    }), (DispatcherPriority)3);

The fix for this issue will be available with the next LIB (version 2018.3.1224) expected on Monday, December 24.

for radgridview,if CanUserFreezeColumns="True" ,
when adjust the FreezeColumnsResizer to the right,and then resize the left colum'width,
if exceed the visual area,these exceed area's column will disappear!
for example,the data virtualization sample for the radgridview,if set the FreezeColumnsResizer
to the 'Unit_Price' column behind,then adjust the 'Product_ID' column width to exceed the visual area,
at last by scroll,you can't find the exceed visual area columns

Currently, caret continues to blink even when typing or navigation is in progress (e.g. arrow key is pressed and held), which is inconvenient for the end users. Instead, the caret should stop blinking during these operations, similarly to industry standard apps like MS Word and OpenOffice.

The issue is related to specific steps and is a regression released in R3 2018.

Steps to reproduce:
1. Run RadRichTextBox and insert "test" at the beginning of the document.
2. Move the caret after the 'e'
3. Press Shift+Enter to insert a line break

Observed: NullReferenceException is thrown and the UI becomes unresponsive.
Expected: The break should be successfully inserted in the content

This exception is thrown because there is field name with special characters which are incorrectly modified during the recalculation process of widget appearances. This exception is thrown in the internal RecalculateMissingAppearances method or in RecalculateWidgetAppearancesOld method.

Page field in header (or footer) of document created with mail merge is always evaluated to 1, instead of the number of the current page.

Possible workaround (attached):

- Do mail merges one by one
- Set header/footers anew to contain PAGE fields in each document
- Set FirstPageNumber = 1 to each first section in each document
- Merge with RadDocumentMerger

Hyperlinks within a document are not working via touch. They are working only when a mouse is used.

Some of the RadSpreadsheet child controls do not apply the new theme, but stay with office black applied when theme is set on control level.
Last Updated: 08 Jan 2019 14:29 by ADMIN

To reproduce this:

  1. Set the ShowToolTipOnTrimmedText property of RadGridView to True.
  2. Hover a cell with trimmed text.
  3. Before the tooltip shows, move the mouse quickly, outside of the RadGridView control.
  4. Regardless of the fact that the mouse cursor is outside of the RadGridView control, the tooltip showing is not canceled and it shows after a second.

To resolve this, set the ShowToolTipOnTrimmedText of the gridview columns instead of the RadGridView control.

Setting the Expanded property of the GroupsExpandBehavior assigned to the RowGroupsExpandBehavior property of RadPivotGrid to True, and the RowSubTotalsPosition to None, leads to an error. 

To work this around set the RowSubTotalsPosition to Top. 

Or set the IsExpanded property of the corresponding PivotGroupHeader controls manually.

public MainWindow()

// the Opacity is used to avoid the flicker that appears because the groups are rendered just before the collapse logic kicks-in.
this.pivotGrid.Opacity = 0;
this.pivotGrid.Loaded += PivotGrid_Loaded;            

private void PivotGrid_Loaded(object sender, RoutedEventArgs e)
Dispatcher.BeginInvoke(new Action(() => { 
var headers = this.pivotGrid.ChildrenOfType<PivotGroupHeader>();
foreach (var header in headers)
header.IsExpanded = false;
this.pivotGrid.Opacity = 1;
}), (DispatcherPriority)3);

The content of the table cells seems to be rendered in the correct position while the borders are drawn above the continues section break.
