Hey,

I'm using RadDiagram in a databound application. For each shape I have some additional information I want to provide. Is there any way to set the Tooltip of a shape? I tried to set the ToolTip property on the shape's style and even in the content of the shape I am not able to have a tooltip on a component. It seems like the Diagram itself disables all tooltips of child elements. Hope you can tell me a way to show tooltips on shapes.

Thank you in advance.

Best Regards,
Peter Schmidt

Memory leak if bounded data doesn't implement INotifyPropertyChanged

Hi,

I use the RadGridView in a very simple way. I bind a collection of simple objects with two string properties and a collection of some arbitrary child objects to the RadGridView. In addition this collection is cleared and refilled every three seconds.

The situation I see is if the class used in the bound collection implements the INotifyPropertyChanged interface everything is fine. If this class does not implement this interface it seems to be leaking and runs out of memory after about 20 seconds (OutOfMemoryException).

Is it really a must to implement this interface even if no data change is necessary?
It's a little bit hard if you want to use an external object and always have to wrap it.

Or is it just a Bug?

Telerik Version: 2011.1.315.40

Thanks and best regards

PS. Is there a way to provide you a sample project? I have a simple one were the effect is clearly seen.

[Solved] Visual Studio behavior on a RadDocumentPane -- cannot see contents

Hi -- I've been working with the RadDocking framework and Prism, and am very happy with the way things are coming.
However, I've run into a snag with the Visual Studio designer for XAML on RadDocumentPane views.

My app is using a custom region adapter from these forums for the RadPaneGroup, which is working great. The views that I create in my other projects are where the issue comes in. The XAML for those views looks something like this (obviously more interesting than just a single hello world button). Note that this is the whole file -- there is no encapsulating user control or anything.

<telerikDocking:RadDocumentPane x:Class="Nwp.BackOffice.Settings.MatchingCriteria.RadDocumentPaneTest"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:telerikDocking="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Docking"

mc:Ignorable="d"

d:DesignHeight="300" d:DesignWidth="300">

<Grid>

<Button>Hello World</Button>

</Grid>

</telerikDocking:RadDocumentPane>

In the designer view, all I can see is a 300x300 grey box -- none of the inside contents. I *can* change it from a RadDocumentPane to a UserControl (top, bottom tags, then any Resources tags, etc. This lets me see the contents properly, but then I have to go back and change it back before compile and run time.

Any insight as to how I might better play with the designer (have tried in VS 2010 Utilimate and VS 2012 Ultimate with same results).

Thanks in advance -

[Solved] Drag Colums Grouped View

Hi,

I have a grid with servere Column Groups.
-- "Base Product" "End Product" "Sales"
And the user is enabled to drag columns.
My problem - the user can now drag the column "Number of items" from Sales to "somewhere".

This results in a "splitted group header".

Is there a (simple) way to restrict dragging of a column within a column group?

And just another question - how can I place text on the default loading indicator?
I found no template for it - and also no property like "Loading content" or so.
All I want to do is to place a text "Loading Items please be..." on the indicator.

Font problem

Hi all,

I'm using the Crystal Reports 9 - "Export to disk file" option to generate pdf file(s) from my reports.
This works fine: I can open the reports using Acrobat Reader and they look perfect. However, as soon as I load the pdf in the RadPDFViewer (version 2012.2.1009.40), the report becomes completely unreadable (replacing the text with strange font characters as if the font is not there).
I tried it with Arial, Times New Roman, Courier, Aharoni... but nothing works.

Strangely enough: If I "print" the same report to a PDF printer to generated the PDF (instead of export), then it works fine !

Any help would be very much appreciated!

Kind regards,
Wim

Everything is fine. I just want to have a button "Custom Color" like in the video or something similar.

Thanks!
