Hi,

From what I understand the purpose of data virtualization is to only keep a finite number of records in memory at any given time.  However, while experimenting I found that the ItemsLoading event only gets called while I scroll down to the bottom of the RadGridView.  Once I am at the final row and start scrolling back up it is no longer being called.  This has led me to believe that records are not being unloaded from memory once they have been scrolled out of view.

I am wondering if I am missing something as I do not see any cache size member to set how many things to hold in memory at one time.  Any guidance on how to properly utilize the VirtualQueryableCollectionView with the RadGridView would be greatly appreciated.  The example posted is for RIA services, but we are not using RIA.

Hello,

how can I change the Style of the FilterRow e.g. to change Background and remove Borders...
It would be great if you have some XAML CodeExamples for that!

Hi All!

  I figured I would post here instead of a trouble ticket as this really is a quest for information more than anything else.  I am sure that you have probably been asked this somewhere by now; but I am not finding anything in the documentation or via the support links, so here it goes!

I have a GridView that is attached to a RadDataFilter and I would like to be able to store in a database the FilterDescriptors and the Logical operators that a user adds/changes/modifies.  I am having a hard time trying to figure out the bes data structure to use to accommodate the storing and retrieval of these filters.  My RadGridView is tied to a view in the database and these filters will be extremely important to keep for the filtering process.

Can someone make a recommendation as to the best approach?  Is there an easy way to "re-build" the RadDataFilter based on the string value found when assessing the values in this property: "radDataFilter.ViewModel.CompositeFilter.ToString()"?  If not a solution could be XML?  Just not sure what is less painful when attempting to store this controls data.  Perhaps I have to store the Binary for the object in the DB and rebuild?

Any assistance or guidance is greatly appreciated!

Thanks!

When the mouse moves over a row in a RadGridView I have to set some fields on the supporting viewmodel object so that visual objects in a different control using the same viewmodel are highlighted.

Is this doable with our current version of Telerik.Windows.Controls (2012.2.0725.40)?

Thanks,

Hi,

There are certain meetings (Appointments) that has fixed timing, i.e. they need to be held at that time only. There are other meetings on the same day which may be held on any given time in a day.

I need to show the meetings with fixed timings first and then the meetings with no timings. I need to show them one below other (Not side to side). Even if two meetings have same timings, they need to be shown one below the other.

Let me know if this is possible or not.

If I open any DOCX file, I get an error saying the file is locked and cannot be opened.  This is definitely not true.

I then pulled Telerik source code and ran.  I found that the error is in the Telerik.Windows.Documents.dll file.  The error is in Paragraph.cs.  The error is at line 409.  As you can see by the photo, the Levels only contains one item, yet it's trying to reference Item[1] which would be impossible.  Should be Item[0].

I can attach a DOCX file if no one else has this issue.

Hi,

I want to design a grid which will display the values as in the attached image. Column headers and row headers have to be populated dynamically, Since i am following MVVM-Wpf pattern i will bind it through my observsable collection. How can i acheive this?

Vertical orientation blocks both vertical and horizontal scrolling; None blocks only horizontal scrolling for some reason. Bug?
Example

I'm using RadWindow as ModalDialog in a WPF application. The content of the window expands with Expander.
When I set RadWindow property TextOptions.TextFormattingMode="Display", window stops to change its size automatically and cut my content.

Without setting this property, auto resizing works fine.

Example for reproducing a bug:
