Available in LIB version 2015.3.1019, it will be also available in the 2015 Q3 SP1.

When the UI culture changes, the DataMemberBinding is updated for all columns (I'm wondering why?). See \Controls\GridView\GridView\GridView\GridViewDataControl.cs:

private void UpdateCultureInfoIfNeeded()
{
	if (this.cultureInfo != null && (this.cultureInfo.Name.ToUpper(this.cultureInfo) != this.Language.IetfLanguageTag.ToUpper(this.cultureInfo)))
	{
		this.InitializeCultureInfo();
		foreach (var column in this.Columns.OfType<GridViewBoundColumnBase>())
		{
			Binding oldBinding = column.DataMemberBinding.CloneBinding(column.ValidatesOnDataErrors);
			column.DataMemberBinding = oldBinding;
		}
	}
}

However, if the DataMemberBinding was null, the CloneBinding creates a new binding with empty path instead of returning null again - but this never makes sense for the DataMemberBinding on a column (crashes the application as soon as the Binding is applied to the cells).

Background: I have created a column where the cell value is not bound but dynamically calculated - so the DataMemberBinding is null.

The fix will be included in our LIB v. 2015.02.0810.

Some styles are duplicated in VisualStudio2013 theme. For example:

For example, RadButtonStyle is located in:
-Telerik.Windows.Controls.Data.xaml
-Telerik.Windows.Controls.Navigation.xaml
-Telerik.Windows.Controls.Input.xaml

This creates conflicts when I try to change default style of a RadButton because other styles are applied instead.

Reason for declination: 
We understand that having duplicate styles can be annoying for our customers. However in Silverlight the base style in a resource dictionary cannot be omitted. As for WPF, it is possible but will lead to exceptions if there is a missing resource dictionary or wrong order of the merged dictionaries which would be unwanted change for our customers. 

That is why we suggest our customers to merge their custom styles after Telerik default ones thus maintaining and upgrading is easier. Another option (in WPF) is using a custom build of our themes where all unwanted duplicates are removed. If you choose the second, you will need to remove button's style from all XAML files except the Telerik.Windows.Controls.xaml one and edit it there.

I am using Prism with Telerik Control (RadTileView). while application i got this this exception"Could not load file or assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified"

Please help on this,

=====================
DECLINED DUE TO INACTIVITY.

If there is a way to do this, I would love to know. It is driving my users crazy.

You example of the mask token are as follow
XAML

<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
    <TextBlock Text="Mask: A" />
    <telerik:RadMaskedTextInput Margin="0,5,0,10" Mask="AAAAAA" />
    <TextBlock Text="Mask: a" />
    <telerik:RadMaskedTextInput Margin="0,5,0,10" Mask="aaaaaa" />
    <TextBlock Text="Mask: L" />
    <telerik:RadMaskedTextInput Margin="0,5,0,10" Mask="LLLL" />
    <TextBlock Text="Mask: l" />
    <telerik:RadMaskedTextInput Margin="0,5,0,10" Mask="llll" />
    <TextBlock Text="Mask: \" />
    <telerik:RadMaskedTextInput Mask="\#\\###" />
    <TextBlock Text="Mask: Any other characters" />
    <telerik:RadMaskedTextInput Mask="N\ame: llll" />
</StackPanel>

and the result should be as follow
Mask A = Aa1 +;
Mask a = Ab-,"

which is fine.
But if I use any of the capital A or L, in the MVVM, the binding is not working anymore.

I have attached a file.
Run the program and press add button
Enter info in First Name, then enter info in Last Name.
Put a break point in the file RecipientData.cs at the properties FirstName on get and set, and do the same for LastName properties.
In the xaml, the only difference between those 2 controls one the Mask="&gt;L1A29" for the first name and Mask="&gt;l1a29" for the last name.  I do not know what is going on behind the scene of this control, but I know there are some issues.

REASON FOR DECLINATION
This is expected behavior in the MaskedInputControls. Please read more in the comments.

When you place items in the gallery there are scenarios where the tooltip of the scroll up/down buttons is not correct.

Available in LIB version: 2014.3.1402

Steps to reproduce:

1. Set focus to the Body Text Area and insert some text (using typing or copy/paste).
2. Try to select a part of text for editing/removing:
---> [BUG]: The system shows error message and after that is frozen.
And for further work it's necessary to restart the system.
Please look at attached files.

We use successor of System.Windows.Controls.Button in the tile. 
The button's Command property is bound with ICommand implementation instance. It works ok on mouse click but doesn't work on touch. On touch it only gets focus but command doesn't executed.

We have not tried with onClick handler because we use MVVM.

Sample project to reproduce the problem is attached.

The email was rejected somehow, so I post the reply here.

And you website can NOT upload any file!

Alex,
I have still evaluated the UI for WPF. 

I found the component is not so compatible with Chinese which it is addressed as following snapshot:

1) Define some Chinese menu in XAML(Use one of demo example you provided)
 

2) compile error: Invalid  character  specified, line 31, position 54, .'' XML invalid.
 

3) If the menu is changed to ASCII, it compile successful.

I hope the problem will be solved A.S.A.P before I make a decision.

Regards,

Hi Sun,

To follow up on my previous email, I was curious how your evaluation is going?

I also wanted to check in to see which resources (support tickets, forums, blogs, Telerik TV) you found the most useful during your evaluation, and if you encountered anything that would prevent you from recommending Telerik?

Your feedback is greatly appreciated.

Hi Sun,

I noticed you recently downloaded a 30 day trial of UI for WPF. 

Please do not hesitate to contact me with any questions that come up during your evaluation period. I would be happy to help you.

I will be in touch next week to see how your evaluation is going.

Try to evaluate the financial dashboard based on RadDiagram WPF solution ,  but cannot build because the tag Metrotheme doesn't exist in XML namespace.

This problem is resolved with lib version 2014.2.721.

I found a memory leak when using RadComboBox inside TabItems that are dynamically added or removed from a TabControl: even if the tab is removed, the TabItem instance stays in memory due to an instance of RadComboBox that is not collected.

If the tab has a DataContext, that may be huge memory parts that cannot be collected!...

Please find enclosed an example of WPF application that helps to reproduce the problem.

When the custom map tiles provider returns the tiles up to the certain zoom level and the user zooms the map to the level above the supported level then the map should use available tiles from previous zoom level, but it show gray patches instead. It occurs when the custom map tiles provider returns null for unavailable tiles.

When user opens the mini map and changes the zoom level of the map then the MapShapeData objects in VisualizationLayer jump and aren't positioned to correct location. This effect is kept even when the user closes mini map.

This exception could be thrown once in a while when the layer is unloaded.
