Performance difference between Print Layout and Web Layout

Dear Telerik,

For big documents +150 pages, I've noticed a very big performance difference between, the printlayout (typing is increadibly slow) and the weblayout (no noticable performance penalities compared to small documents).

Is there any commitment or roadmap to tackle the performance of the RadRichTextBox?

Kind regards

Changing Area Series Fill Opacity Within A ChartSeries Provider

I'm in need of having a dynamic number of area series overlap each other in a meaningful way, and therefor I'm attempting to track down a way to set the areaseries fill property's opacity property, I have not yet been successful in any way shape or form to do so. The Xaml is shown below, any aid is greatly appreciated.

<telerik:RadCartesianChart DockPanel.Dock="Bottom" x:Name="UnderWaterEquityCurve" Palette="Windows8">

<telerik:RadCartesianChart.Grid>

<telerik:CartesianChartGrid MajorLinesVisibility="Y"/>

Winform PropertyGrid in RadWindow

Hi,
as there have been some problems using RadPropertyGrid (I've posted the issues in the forum lately), I'm temporarily using Winform PropertyGrid instead. However, Winform PropertyGrid doesn't even show up when I tried to place it in RadWindow. Can you please test it or hopefully, get the RadPropertyGrid's converters to work? (Please refer to http://www.telerik.com/community/forums/wpf/property-grid/propertygrid-problems-in-2013-q2.aspx)
Thanks.

Physical-Logical Caret Position Mismatch

I'm working on getting a simple project together to try and recreate the issue and will post when I get it together.

I'm experiencing something similar to this thread from 2011. Inside of a long form RichTextBox the "physical" position of the caret onscreen does not match the logical position of the caret and when inserting or deleting the effect is quite disconcerting.

What we have noticed is that the effect is accentuated primarily by the distance from the beginning of the text block. If the block of text is large (2K+) the offset is greater at the end of the document than near the beginning and, in fact, the first two or three paragraphs may not show any offset at all.

Font family and size do appear to have some effect on the problem but there does not appear to be any font/size combo (I worked hard at testing fixed-width fonts thinking they might not show the issue being, after all, fixed width) that works reliably.

From a layout perspective we have...
+ A master view that contains
+ A RichTextBoxRibbon
+ A Tab View that contains
+ A Wizard View on one tab
+ The RadRichTextBox within a user control

As I'm working on a sample project to illustrate is there any insight that might be offered if anyone else has run into this before and it was a simple fix?

Thanks!

Set tooltip in MonthItemTemplate

Hi,

We are currently customizing The radscheduleview with a lot of custom styles and templates. One of the customer's requirements is to associate a remark with a date, We try to make this visible in the Radscheduleview by styling the TimeRulerItemTemplateSelector.MonthItemTemplate:

<DataTemplate

<Grid

<TextBlock HorizontalAlignment="Left" Text="{Binding FormattedValue}"

/>

<Image Height="15" HorizontalAlignment="Right" Margin="0,0,100,0" Source="pack://application:,,,/Images/speech_bubble.png"

<Image.ToolTip

<TextBlock Text="Hi! I'm a tooltip"

/>

</Image.ToolTip

</Image

</Grid

</DataTemplate>

It's a very simplistic example, in our app we bind the text and visibility, but this has the same issue:
The Balloon displays nicely (image in attachment), but unfortunately the tooltip never pops up when you hover over the image. I guess this has something to do with the style, I'm guessing Zindexes but after experimenting a bit with the default styles I can't get the tooltip to show..

Any suggestions?

Thanks in advance!

EDIT: we use the Windows8 theme btw

DataBinding and Click and Drag Connection

Hi

I'm trying to implement a diagram control using databinding. But I'm unable to use creating connections by click on one of the shape's port and drag it to another shape's port like the examples in the WPF demo. I've tried to set "IsConnectorManipulationEnabled" to true that doesn;t work either. I've attached my GraphSourceBase code below. Any suggestions to enable the default connector behaviour in databinding method ?

public class CMGraphSource : GraphSourceBase<CMDeviceShapeViewModel, ILink>

{

public CMGraphSource()

{

//Load initial objects into CMDiagram (Reciever and USBTripods)

int TripodCount = ConnectionHandler.Instance.getUSBTripodCount();

for (int i = 0; i < TripodCount; i++)

{

Tripod t = ConnectionHandler.Instance.getUSBTripod(i);

AddItem(new TripodCMViewModel(t.id));

}

int RecieverCount = ConnectionHandler.Instance.getRecieverCount();

for (int i = 0; i < RecieverCount; i++)

{

Reciever r = ConnectionHandler.Instance.getReciever(i);

AddItem(new RecieverCMViewModel(r.id));

}

ConnectionHandler.Instance.PropertyChanged += onConnectionHandlerDeviceChange;

}

private void onConnectionHandlerDeviceChange(object sender, System.ComponentModel.PropertyChangedEventArgs e)

{

if (e.PropertyName.Equals("AddReciever", StringComparison.InvariantCultureIgnoreCase))

{

Reciever r = (Reciever)sender;

AddItem(new RecieverCMViewModel(r.id));

}

else if (e.PropertyName.Equals("RemoveReciever", StringComparison.InvariantCultureIgnoreCase))

{

Reciever r = (Reciever)sender;

}

else if (e.PropertyName.Equals("AddUSBTripod", StringComparison.InvariantCultureIgnoreCase))

{

Tripod t = (Tripod)sender;

AddItem(new TripodCMViewModel(t.id));

}

else if (e.PropertyName.Equals("RemoveUSBTripod", StringComparison.InvariantCultureIgnoreCase))

{

Tripod t = (Tripod)sender;

}

public void AddItem(CMDeviceShapeViewModel model)

{

if (base.InternalItems.Contains(model))

return;

base.AddNode(model);

}

Problem using RadGridView - unable to load file or assembly Telerik.Windows.Controls.GridView

Hello, I'm having an issue using the GridView..

I have an application (x86) that references several assemblies (any cpu)
The application references a WPF user control library, which contains, among many other parts, a window with a RadGridView.
When code wants to open this window, I get the following exception in the constructor:

Could not load file or assembly 'Telerik.Windows.Controls.GridView, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The system cannot find the file specified.

What is going on here?
