Blend designer view crashes when adding a PropertyGridField control

Hi there,

I'm trying to style the property grid chrome, but whenever I drag a <telerik:PropertyGridField/> to the design view, I get a red box error (see attached).

Could someone give me the XAML of the default style & template so I can edit without adding a PropertyGridField control?

Many thanks

Felix

Creating a CellStyleSelector as a reusable resource

Hello,

I am using a telerik:RadGridView with is bound to a collection.

In a column of have the following CellStyleSelector

<telerik:GridViewDataColumn.CellStyleSelector>
<telerik:ConditionalStyleSelector>
<telerik:StyleRule Condition="Name= 'N/A'">
<telerik:StyleRule.Style>
<Style TargetType="telerik:GridViewCell">
<Setter Property="IsEnabled" Value="False" />
</Style>
</telerik:StyleRule.Style>
</telerik:StyleRule>
</telerik:ConditionalStyleSelector>
</telerik:GridViewDataColumn.CellStyleSelector>

This works perfectly for me. However I want this CellStyleSelector on every column expect the Name column.

Is it possible to add a CellStyleSelector as a XAML resource so I can reuse it.

e.g

<telerik:GridViewDataColumn CellStyleSelector="{StaticResource MySelector}" Name="colage" Width="50" Header="Age" DataMemberBinding="{Binding Age, Mode=TwoWay}" />

I am aware I could create a style selector class but i would prefer to keep it all in the XAML

Document Line Numbers

Has anyone tried to put line numbers down the side of a document? Just like what you get with a code compiler.

Thanks,

AutoComplete - Programmatically

Hi,

Is it possible to set the AutoComplete text programmatically?

I have the following ListBox:

<telerik:RadListBox MinWidth="100" MaxHeight="250" x:Name="radListBox"

Grid.ColumnSpan="2" Visibility="Collapsed"

HorizontalAlignment="Left" VerticalAlignment="Top"

CanAutocompleteSelectItems="True" IsTextSearchEnabled="True" TextSearchMode="Contains" TextPath="Name"

ItemTemplate="{StaticResource AutoCompleteListBoxTemplate}"

ItemsSource="{Binding autoCompleteListItems}"

MouseDoubleClick="radListBox_MouseDoubleClick" MouseUp="radListBox_MouseUp">

<telerik:RadListBox.Effect>

<DropShadowEffect ShadowDepth="10" Color="Gray" Opacity=".4" Direction="320" RenderingBias="Performance" />

</telerik:RadListBox.Effect>

</telerik:RadListBox>

The ListBox uses this template:

<DataTemplate x:Key="AutoCompleteListBoxTemplate">

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition />

</Grid.ColumnDefinitions>

<Image Style="{StaticResource AutoCompleteListBoxIcon}" Width="10" Height="10" Margin="0,0,10,0" />

<TextBlock Text="{Binding Name}" Grid.Column="1" HorizontalAlignment="Stretch" />

<TextBlock Text="" Grid.Column="2" HorizontalAlignment="Right" Margin="5,0,5,0" />

</Grid>

</DataTemplate>

I set the ItemsSource in code behind:

private void radRichTextBox_Loaded(object sender, RoutedEventArgs e)

{

//Set Autocomplete ListBox itemssource

radListBox.ItemsSource = autoCompleteListItems;

}

The documentation does state the following:
RadListBox has full autocomplete support - while the control is focused, you can type certain keys and the listbox will select the relative match for the currently typed text.

I'm building a RichTextBox Intellisense application, thus the ListBox is the Intellisense. The application is setup to always send focus back to the RichTextBox so that the user can continue typing.

Is it possible to set the ListBox AutoComplete text in code behind? i.e. when the user types text in the RadRichText box, the text they type is used to set AutoComplete the ListBox.

I've tried setting the TypedText property:
listBox.TypedText = "He";

However this doesn't seem to do anything.

Thank you very much,

Rob

Header issue

Hi,
I tried to put two lines in header. The first page´s header its ok when i print it, but the next pages the header changes like this:

first page´s header:

---------------------------------------------------------------------------------------
Title
date
---------------------------------------------------------------------------------------

next page´s header:
---------------------------------------------------------------------------------------
date
Title
---------------------------------------------------------------------------------------

This is the code:

RadDocument headerDoc = new RadDocument();

RadDocument footerDoc = new RadDocument();

Section hSection = new Section();

hSection.PageOrientation = PageOrientation.Landscape;

headerDoc.DefaultPageLayoutSettings = new PageLayoutSettings(PaperTypes.A4);

headerDoc.SectionDefaultPageOrientation = PageOrientation.Landscape;

headerDoc.Sections.Add(hSection);

headerDoc.SectionDefaultPageMargin = new Telerik.Windows.Documents.Layout.Padding(5, 5, 5, 5);

Paragraph hparagraph = new Paragraph();

hSection.Blocks.Add(hparagraph);

Span hspan = new Span("Title");

hspan.FontSize = 20;

if (!string.IsNullOrEmpty("Title"))

hparagraph.Inlines.Add(hspan);

Paragraph h2paragraph = new Paragraph();

h2paragraph.TextAlignment = RadTextAlignment.Right;

hSection.Blocks.Add(h2paragraph);

var fecha = DateTime.Now;

Span h2span = new Span(fecha.ToString());

h2span.FontSize = 10;

h2paragraph.Inlines.Add(h2span);

Section fSection = new Section();

fSection.PageOrientation = PageOrientation.Landscape;

footerDoc.DefaultPageLayoutSettings = new PageLayoutSettings(PaperTypes.A4);

footerDoc.SectionDefaultPageOrientation = PageOrientation.Landscape;

footerDoc.Sections.Add(fSection);

footerDoc.SectionDefaultPageMargin = new Telerik.Windows.Documents.Layout.Padding(5, 5, 5, 5);

Paragraph fparagraph = new Paragraph();

fSection.Blocks.Add(fparagraph);

Span fspan = new Span("Footer");

fspan.FontSize = 30;

if(!string.IsNullOrEmpty("Footer"))

fparagraph.Inlines.Add(fspan);

Header header = new Header();

Footer footer = new Footer();

header.Body = headerDoc;

footer.Body = footerDoc;

Section section = new Section();

section.PageOrientation = PageOrientation.Landscape;

section.Headers.Default = header;

section.Footers.Default = footer;

return section;

Thank you, for your service.

custom year X-Axis

Hi Telerik-Team,

i'd like to customize the X-Axis, but i can't figure out how to solve the problem.

I'd like to have 12 marks on the X-Axis that represent the 12 months of the year,
but only the quarter marks should display text like Q1/2012, Q2/2012...

Do you have any idea?

kind regards
Hubert

Click Through Transparent Background

Hi there,

I am trying to use the docking as overlay to my existing WPF application.

I did set the background of the docking to transparent, but I can not click on the items behind it.

If I set ishittestvisible to false then I can click on the items behind the but I can not click on any item in the docking panes anymore.

Is there any trick to archieve this.

My goal is to have a streched docking over my entire application in order to bring in tools from all sides while being able to interact with the underlying grid of controls.

Any hint would be appreciated.

Unhandled COMException when scrolling through a PDF document

Hello,

We have created a small WPF-application which is used to display PDF-files. Although the application works fine on some machines, on others we get an unhandled COMException when we scroll through the document's pages. The exception is not always thrown on the same page and the size of the document or the speed of scrolling does not seem to have an influence.

The documents we tried to display are not corrupt and can be viewed perfectly with other PDF-viewers. The PDF documents are also quite small (+/- 10 pages).

Below you find the call stack of the exception.

Application: PdfViewer.exe

Framework Version: v4.0.30319

Description: The process was terminated due to an unhandled exception.
