When I open my project it is constantly reminding me that my project doesn't use the latest version of the WPF controls. But I can't seem to permanently turn off this notification. I can only tell it to remind me later.

Is there away to tell the extension not to remind me again for this project? When the time comes that I want/need to update, I will do a manual update. This project is source controlled on TFS so I'd rather not use an automatic update.

The new update to my trial version contains binaries for WPF40 and WPF45.  I am using VS 2010.  Which should I use; WPF40 or WPF45?

There seems to be a Bug within the MaskedTextInputControl. When I set the Mask to Alphanumeric ( f.e. a20 ) I can hit return to break the line. When Setting Mask to literals ( f.e. l20 ) this behavior disappers.

Is there a known workaround so I can set my TextInput to alphanumeric without being able to break the line ?

Bug can be easily reproduced at the Demo

What's wrong with this code???
why binding doesn't work???

The following xaml give me an error (Could not load file or assembly 'Telerik.Windows.PersistenceFramework...) during runtime:

I am trying to write a C# program in wpf that retrieves the content of a web page.

The first thing I tried was to try the WebRequest and WebResponse classes.  This did not provide the actual displayed content.  WebResponse reveils the HTML code that is sent to the browser.  But I discovered that, while the page is being loaded by the browser, javascript can change what content is finally displayed in the browser.

So I decided to use the WebBrowser class.

Immediately I found that there are two WebBrowser classes.  Thee is the one that is documented for WinForms and there is another that is documented for WPF.  I need to understand the one documented for WPF.  What I think I neeed to know what to do is to retrieve code after the "LoadCompleted" method is caused.  But I do not know how to this and I cannot find any example demonstrating how this is done.

 

Not sure what info to write, but wanted to get this thread started. I have a project with 2 UI developers. I run some of the testing and builds on my machine.

The UI guys can pull data for some grids and it displays just fine. No issues. I will get latest, compile and run the app. I see the data everywhere except for 3 particular grids. All grids are coded up the same way-same design pattern. Also, we use mvvm style.

The UI developers compiled and ran on 5 different machines (VMs, physcials win7 and win8) The data in the grid always appears.

I am running win7 on a VM. I have the same version of telerik controls installed.

any ideas?

thanks

Hi,

I'm version 2012.3.1017.40 and trying to enabled the TrackBar Behavior on a double-click on the chart's data area and then disable it with another double click.  I keep getting an exception when I try to disable it.  I'm wondering if this is a bug with the control, or is it the way I'm trying to disable it?

Here is how I'm trying to Enable/Disable the TrackBall behavior:

It throws an System.ArgumentNullException, {"Value cannot be null.\r\nParameter name: key"},  when I try to disable it with the following StackTrace:

Thanks,

Please find the sample project here

The sample application is divided into two parts:

The bottom part is similar to the RadListBox drag-n-drop demo with 4 elements:

1. RadListBox bound to ObservableCollection<Country> CountryList
2. RadListBox bound to ObservableCollection<Country> GroupA
3. RadListBox bound to ObservableCollection<City> GroupD
4. WPF ListBox bound to ObservableCollection<Country> GroupA, AllowDrop unset
   

The Drag-n-Drop behaviour is as expected, I can drag n drop between 1&2, but not to 3 or 4, it worked very well.

The top part is the identical setup, except it is contained within a RadTileView, and there are a few unexpected behaviours:

1. Cursor no longer change to Cursors.No when drag over list 3 & 4
2. When dropped on list 3, nothing happens, this is good. But when dropped on list 4 or anywhere on the tileview that's not a RadListBox, the item is removed from the drag source, and not added to anywhere.

Hi All,

I want create the RadGridView Control with Editable Rows. Once i Edit the GridView's last row then pressing enter should add the new row and focus should be in the First column. Can you guide me on this? Also if there is any sample please share with me...

Thansk and Regards,
Sakthi
