Hello All,

Found another bug in the RadWindow control.  The attached exception is thrown once in a while due to an unchecked conidtion in the WindowHostBase class.

The fix is below but you will have to compile it yourself until they get around to fixing their code product. 

1) In the 'Telerik.Windows.Controls.InternalWindow.WindowHostBase' class you will see the BringToFront method defined as:

replace this function with:

 and the issue goes away.

Hi,

I am using the RadSpreadsheet to manipulate a workbook which I exported and stored in a database.

Once imported back from the database I allow the user to modify the workbook. I am detecting when the user makes a change to the content using the WorkbookContentChanged event. If a change is detected I enable my apps save button to allow the user to save the workbook back to the database.

My issue occurs when I try to do things such as rename a worksheet or freeze panes. The WorkbookContentChanged event is not fired and therefore the user will not be given the option by my app to save the workbook back to the database.

Is there another event I can hook up to or is this a bug with the WorkbookContentChanged not firing for some changes?

Thanks
Anthony

When I select a single line(See screenshot 1) and convert into an annotation range using InsertFragment, it is getting inserted.  (See screenshot 2).

But, when I select multiple lines(See screenshot 3), InsertFragment is not working.

Code Sample:

            RadDocument associatedDocument = associatedRichTextBox.Document;
            DocumentSelection selection = associatedDocument.Selection;
            DocumentPosition documentPosition = associatedDocument.CaretPosition;

            string selectedText = GetSelectedText(associatedDocument);

            RadDocument tempDocument = new RadDocument();
            Section section = new Section();
            Paragraph paragraph = new Paragraph();

            try
            {
                //BookmarkRangeStart bookmarkRangeStart = new BookmarkRangeStart();
                //BookmarkRangeEnd bookmarkRangeEnd = new BookmarkRangeEnd();
                //bookmarkRangeEnd.PairWithStart(bookmarkRangeStart);

                //paragraph.Inlines.Add(bookmarkRangeStart);
                //paragraph.Inlines.Add(bookmarkRangeEnd);

                HeadingRangeStart headingRangeStart = new HeadingRangeStart();
                HeadingRangeEnd headingRangeEnd = new HeadingRangeEnd();
                headingRangeEnd.PairWithStart(headingRangeStart);

                Span spanSelectedText = new Span(selectedText.TrimEnd());
                spanSelectedText.FontWeight = FontWeights.Bold;
                spanSelectedText.ForeColor = Colors.Red;

                paragraph.Inlines.Add(headingRangeStart);
                paragraph.Inlines.Add(spanSelectedText);
                paragraph.Inlines.Add(headingRangeEnd);

                section.Blocks.Add(paragraph);
                tempDocument.Sections.Add(section);
                tempDocument.MeasureAndArrangeInDefaultSize();
                tempDocument.Selection.SelectAll();

                associatedRichTextBox.UpdateEditorLayout();
                associatedRichTextBox.InsertFragment(tempDocument.Selection.CopySelectedDocumentElements(true));
                associatedRichTextBox.Document.Selection.Clear();

                associatedRichTextBox.UpdateEditorLayout();
            }

Please suggest a solution.

Dear support,

in Excel the cell format "#.##0,00;-#.##0,00;;@" suppresses values equal zero i.e. no value is displayed in the cell.

This format-string does not work in your spread sheet. Is there another format string to achieve this.

Thanks in advance

Hi ,

I was trying to import the data using RTFFormatProvider.import(string) method.
It is taking so much time to execute this.
The parameter which i was passing has more than 5Lakhs characters.
Do we have any alternative or something else to improve this performance.

Note:I am getting data from the above method but the only thing is taking so much time.

Could you pls throw your thoughts on this.

Hello Telerik

I would like to publish some source code examples in my Bog, among other things with Telerik-Controls. But of course I do not want to use the regular Telerik Dlls. Is there a link to download your demo dlls, which you also get when creating a test account.

Greetings Uwe

Hello, I want to reference the default template of the MilestoneContainer but I don't achieve this.
the goal is to use the default template and override when a dataTrigger is firing
I try to only define the data trigger
<Style BasedOn="{StaticResource ResourceKey={x:Type telerik:MilestoneContainer}}" TargetType="{x:Type telerik:MilestoneContainer}">

                    <Style.Triggers>
                        <DataTrigger Binding="{Binding Converter={StaticResource ObjectAndTypeToVisibilityConverter}, ConverterParameter={x:Type vm:GanttTaskModelePlanningFamille}}" Value="True">
                            <Setter Property="Template">
                                <Setter.Value>
                                    <ControlTemplate>
                                        <Rectangle Width="3"
                                                   Height="24"
                                                   Fill="{TemplateBinding Background}" />
                                    </ControlTemplate>
                                </Setter.Value>
                            </Setter>
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
It's no working, trigger have no action
I try to reference the default template in my style definition (to force the trigger)
<Setter Property="Template" Value="{StaticResource MilestoneContainerTemplate}" />
But still not working, the resource is not know
I also try to do reference at resource using the telerik dll, but the import failed (build failed)
<ResourceDictionary Source="pack://application:,,,/Telerik.Windows.Controls.GanttView;component/Telerik.Windows.Controls.GanttView.xaml" /> 

Have you any idea how I can solve my problem ?

Thanks

I came across a strange case when I was writing code for saving FilterDescriptors settings for RadDataFilter. The default value for string filter editor is OperatorValueFilterDescriptorBase.UnsetValue, the FilterDescriptor.Value is equal to OperatorValueFilterDescriptorBase.UnsetValue (FilterDescriptor .Value == OperatorValueFilterDescriptorBase.UnsetValue). When I save and read this value from isolated storage is not equal to OperatorValueFilterDescriptorBase.UnsetValue. See example bellow.

The following example is completely useless but it shows error.

MainWindow.xaml:

MainWindow.xaml.cs

For one TextBox I save or read data to isolated storage.

UnsetValuePropertyProvider.cs:

UnsetValueProxy.cs:

In ProvideValue method I pass to proxy object OperatorValueFilterDescriptorBase.UnsetValue value and in RestoreValue unsetValueProxy.Value is not equal to OperatorValueFilterDescriptorBase.UnsetValue and it should be. See also locals tab in debug mode (example.png).
