Hi,

I would like to modify PopUp template of the RadAutoCompleteBox to have grouped items result, like that:



​Group 1
       ItemFound 
       ItemFound 
       ...
Group 2
      ItemFound 
      ItemFound
      ...


Can we do this with the built-in functionalities?
Otherwise, how can i do that? Some clues?

We are using RadRichTextBox with Default Spell check feature.

We found that SpellCheck could not change incorrect words within Annotation Ranges().

Is there any way to make spellcheck work for annotation ranges.

In WPF RadRichTextBox, we try to Insert AnnotationRanges using InsertFragment method. But, it throws exception in some scenarios when Track Changes is ON. Please find sample code below.

try
            {
                //Initialize
                RadDocument associatedDocument = associatedRichTextBox.Document;
                DocumentSelection selection = associatedDocument.Selection;
                DocumentPosition documentPosition = associatedDocument.CaretPosition;

                string selectedText = GetSelectedText(associatedDocument);

                // If text is not selected 
                if (String.IsNullOrEmpty(selectedText) && String.IsNullOrWhiteSpace(selectedText))
                {
                    MessageBox.Show("Please select a text", "Information", MessageBoxButton.OK, MessageBoxImage.Information);
                }
                else
                {
                    RadDocument tempDocument = associatedDocument.Selection.CreateDocumentFromSelection();

                    IEnumerable<FormulaRangeStart> formulaMarkers = tempDocument.GetAnnotationMarkersOfType<FormulaRangeStart>();

                    bool bformulaRangeExistsInSelection = false;
                    foreach (FormulaRangeStart frmla in formulaMarkers)
                    {
                        bformulaRangeExistsInSelection = true;
                        break;
                    }

                    if (bformulaRangeExistsInSelection)
                    {
                        MessageBox.Show("Selection already contains a formula range", "Formula Information", MessageBoxButton.OK, MessageBoxImage.Information);
                        return;
                    }

                    FormulaRangeStart formulaRangeStart = new FormulaRangeStart();
                    FormulaRangeEnd formulaRangeEnd = new FormulaRangeEnd();
                    formulaRangeEnd.PairWithStart(formulaRangeStart);

                    tempDocument.CaretPosition.MoveToFirstPositionInDocument();
                    tempDocument.InsertInline(formulaRangeStart);

                    tempDocument.CaretPosition.MoveToLastPositionInDocument();
                    tempDocument.InsertInline(formulaRangeEnd);

                    tempDocument.Selection.SelectAll();

                    IEnumerable<Paragraph> paragraphs = tempDocument.Selection.GetSelectedParagraphs();

                    foreach (Paragraph paragraph in paragraphs)
                    {
                        foreach (Telerik.Windows.Documents.Model.Inline inline in paragraph.Inlines)
                        {
                            if (inline is Span)
                            {
                                ((Span)(inline)).HighlightColor = Colors.DarkGray;
                            }
                        }
                    }

                    tempDocument.CaretPosition.MoveToLastPositionInDocument();

                    Span spanResetBgColor = new Span(FormattingSymbolLayoutBox.SPACE_SYMBOL_VISUAL);
                    spanResetBgColor.HighlightColor = Colors.White;
                    tempDocument.InsertInline(spanResetBgColor);

                    tempDocument.Selection.SelectAll();

                    associatedRichTextBox.IsTrackChangesEnabled = true;
                    associatedRichTextBox.TrackChangesOptions.TrackFormatting = true;

                    associatedRichTextBox.InsertFragment(tempDocument.Selection.CopySelectedDocumentElements(true));
                    associatedRichTextBox.Insert(FormattingSymbolLayoutBox.ENTER);
                    associatedRichTextBox.Document.Selection.Clear();
                    associatedRichTextBox.UpdateLayout();
                    associatedRichTextBox.UpdateEditorLayout();
                    associatedRichTextBox.Focus();
                    if (associatedRichTextBox.ActiveEditorPresenter != null)
                    {
                        associatedRichTextBox.ActiveEditorPresenter.RecreateUI();
                    }
                }

Hi, I'm testing WPF UI. In the use of themes I get an error message. Error: "LocalizableResourceExtension" is not valid for "Setter.Value".

I have the following code in my Appliaction.xaml:


Die benötigten xaml-Files habe ich meinem Projekt hinzugefügt und auch die Verweise sind vorhanden. Was mache ich falsch?

Hello, I would like to enquire on a solution to the problem as per title. This is my code currently:

The ScaleFactors work across all sheets, but the ScrollBar didn't work for any of the sheets.
Doing just sheet1211.ActiveWorksheet = worksheets[0] and set the ScrollBars visibility works, but that's only 1 sheet, and furthermore if I change to the next sheet and back to worksheet[0] again in runtime by interface, the scrollbars will appear again.

So how do I set the visibility across all sheets just like how I set the ScaleFactor?

Thanks for your attention.

In my view model I have a byte[] (called "DocumentBytes") that is read from a .docx file.  I have my view set up like this:


The rich textbox correctly displays the document from the file.  When the user makes a change to the content of the rich textbox and then the textbox loses focus, I need the byte[] (DocumentBytes) to be written back with the updated contents of the textbox, and in the docx format, as it was provided to the DocxDataProvider.

Out-of-the-box this didn't seem to work.  I expected the data provider to just write the value back to my property, but it didn't do that.

So, I tried to implement this myself using my view's code behind:


This caused problems and threw exceptions when I would edit the document's content in the rich textbox, and then click on back on it (the LostFocus event was firing each time I clicked on the rich textbox).

I'm really surprised there isn't a short and concise example in the WPF documentation on this, and it's something I imagine most people have to do.  Perhaps the documentation is there and I just haven't found it.

So, what I'm looking for is a example of how to actually bind a byte[] from my view model, and get the view to write back to that same property when the rich textbox's content is updated.

After exporting a RadSpreadsheet workbook to xlsx format using XlsxFormatProvider, resulting Excel workbook opens within Excel and basic functions seem OK.  However, other simple Excel functions cause Excel to loop.  For example, right-click and select of "Format Cells ..." causes this loop behavior.

I am using runtime UI for WPF version v4.0.30319 and Office 2010.

Thank you!

Hi,

I have a poblem with your RichTextBox control. When i set render options in WPF application like this:

RenderOptions.EdgeMode(dependencyObject, EdgeMode.Aliased);

caret in richTextBox disappeared. To reproduce the problem font size should be set to less then 15 and font style should not be set to italic.

( I think that the problem is thickness of caret and the render of 1px width in this render mode)

Please let my know how to set visibility of caret.

Hi,

Is there a way to show the RadPanelBarItem header to the right instead of left when Orientation="Horizontal". I have only 1 RadPanelBarItem and using it to create a search panel on the left that can be collapsed/expanded.

Thanks

            <telerik:RadPanelBar Grid.Column="0" VerticalAlignment="Stretch" Orientation="Horizontal">
                <telerik:RadPanelBarItem Header="Search" IsExpanded="True" HorizontalContentAlignment="Center">
                            <StackPanel Orientation="Horizontal">
                                <telerik:RadComboBox>
                                    <telerik:RadComboBoxItem Content="Item 1" IsSelected="True" />
                                </telerik:RadComboBox>
                            </StackPanel>
                </telerik:RadPanelBarItem>
            </telerik:RadPanelBar>

Hello,
in an application, I need to display a tool-tip for each column header.
To do so I have defined the column Header property to contain a special-made control that, amongst other, define tool-tip for the header.

Doing so has 2 problems:

  1. The button displayed when the user groups by the column only display a bitmap of the column header. This means, for example, that if the column is not wide enough, the displayed text is truncated.

  2. More important: if the column width is too small, the text is not displayed at all on the column header. But, when grouping by this column, the application crashes: ArgumentOutOfRangeException: The parameter value must be greater than zero.\r\nParameter name: pixelWidth.
The stack of this error is:

It seems that the bitmap snapshot has a negative width.

Both problems can be easily solved if we can define the text to display in the button grouping.
Or perhaps you have a better solution...
