Hi there,

 almost every application in Windows (7) offers a context menu in the upper left corner of the title bar (Chrome even does this without any visible icon). The Telerik RadWindow does not. Even if I try to add a context menu to the image which I use as window icon, the menu does not show up. Can you please tell me how to imitate the (kind of) default context menu of any ordinary Windows application with a RadWindow?

 Cheers,

Marcel

Hello,

when using the RadRichTextBoxRibbonUI tool to create the ribbon, the icons looks in 3D, as in Windows 7.
I'm currently using the Office2013 style and the icons doesn't look the same as the remaining of the application.

Do you have a set of icons that works well with the Office2013 theme?

Hi,

 I have multiple columns in a table, some are editable and some are read only. I want to add show an icon for the header cell to indicate which column is editable.

 If the column is not editable, the icon is hidden.

 Are there any good way to achieve this?

 I have not found any solution yet. It is possible to add an icon to the header cell template, but how do I get the visibility property set based on data column's property IsReadOnly set to true or false? 

Hello Team,

I want to know exact rad chart which will work like "excel scatter with smooth line and markers". I am able to find either scatter with smooth lines( no markers) or scatter points(no lines). I want both in single chart in wpf. Same chart i can find in asp.net and the following is url.

http://demos.telerik.com/aspnet-ajax/htmlchart/examples/charttypes/scatterlinechart/defaultcs.aspx

I mean data points should be highlighted like above. Please let me know your answer.

Thanks,

I am in the process of updating our program from the WPF UI 2013.3 controls to 2015.2. I'm close to completing the changes I need, but I still can't build because I'm getting errors in my ResourceDictionaries:
<ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.GridView.xaml"/>

 All 3 of these (but not the other controls) are throwing the following error when I try to build:

An error occurred while finding the resource dictionary "/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.xaml" .CompanySoftwareName\OurFilePath\App.xaml

I checked my Expression Dark dll file and noticed that it was referencing the 2013.3.xxx versions of the UI files in question, so I tried copy/pasting the 2015.2.xxx value in those locations, but this wasn't successful.
Is there a new version of this expression dark dll that I need? What am I missing?
I'd be glad to hear any suggestions from other users, or support from Telerik staff directly.

Thank you!

I am using VirtualQueryableCollectionView with RadGridView and at the same time multiselection mode.

It was already discussed previously with no real solution as far as I know.

When select all (Ctrl+A) is called, all items are loaded into memory which defeats the virtualization and is useless.

So what are the possibilities to fix it?

• Use single selection mode, which is not a solution.
• Use indexes instead of items.
• Use item identifiers if available instead of items.
• Use proxied item objects with knowledge of loaded state and internally loadable when required, which is quite complex.
• Limit ​maximum number of selected items to reasonable value (LoadSize) and add selection events based on indices.

Just my thoughts. I think I will take the last way... and You?

While using RadGridView with VirtualQueryableCollectionView and moving CurrentPosition with any of MoveCurrent* methods, I have found, that CurrentItem is not loaded when CurrentPosition changes to an index of not yet loaded item (in my case LoadSize is 50 and items are loaded from our WCF service) and thus CurrentItem is null.
The problem is in QueryableCollectionView.InternalGetItemAt where

ignores items loading.

My fix for now is:

It has a drawback that OnCurrentChanged is called twice when this fix is effective.
