Hi
I am using data annotations to validate items in a collection presented in a RadGridView.
It successfully validates a property of an item in the collection e.g. a name is required

// ...

{

public class GroupOfItems

{

[Required(ErrorMessage="Name must be provided!")]

public string GroupName { get; set; }

// ...

I now want to ensure the name is unique within the collection. I have tried adding the [Key] attribute but no error is indicated if I enter another item with the same name. It may be that [Key] is not appropriate in this context.

What can you suggest I do to implement this validation rule?
Thanks
Craig
PS. I'm using C#, WPF, MVVM, Rad Controls for WPF 2012.3.1129.40

Collapsed RadRibbonTab header takes up space

I have a radribbonview defined as this:

<telerik:RadRibbonView IsMouseWheelTabScrollingEnabled="False" ApplicationButtonVisibility="Collapsed" TitleBarVisibility="Collapsed" Background="HotPink">

<telerik:RadRibbonTab HeaderVisibility="Collapsed">

<telerik:RadRibbonGroup />

...

<telerik:RadRibbonGroup />

</telerik:RadRibbonTab>

<telerik:RadRibbonView />

I set the background to hotpink to illustrate my problem. There is only one radribbontab inside the radribbonview - so I really do not need any header for it.

In my program it looks like this (see attached file). The top row of tabs ("Project", "Contacts"... are not part of this problem, my problem is on a radribbonview inside the "Suppliers" tab).

I changed it resently from RadRibbonBar to RadRibbonView because it kept bugging me that RadRibbonBar is obsolete.

How do I make the large "margin" in top go away (the margin is not really a margin - it is where my RadRibbon tab would have had it's header if it had one). Anything else I need to collapse?

Thanks

GridViewDataColumn's CellEditTemplate navigation issue

Hello telerik team. I have problem with CellEditTemplate navigation. I have GridViewDataColumn with RadMaskedNumericInput CellEditTemplate:

<telerik:GridViewDataColumn Name="RateColumn" DataMemberBinding="{Binding Rate,Mode=TwoWay}"

Header="{x:Static properties:Resources.CurrencyRateHeader}" DataFormatString="{} {0:#########0.00000000}">

<telerik:GridViewDataColumn.CellEditTemplate>

<DataTemplate>

<controls:RadMaskedNumericInput InputBehavior="Insert" Value="{Binding Rate, Mode=TwoWay}"

IsClearButtonVisible="False" Mask="##.########" FormatString="########00.00000000"

SpinMode="PositionAndValue"

UpdateValueEvent="PropertyChanged"

SelectionOnFocus="SelectAll"

KeyboardNavigation.TabNavigation="Local"

HorizontalAlignment="Stretch"

/>

</DataTemplate>

</telerik:GridViewDataColumn.CellEditTemplate>

</telerik:GridViewDataColumn>

The problem is in navigation: when i'm ending editing of this cell i cannot navigate to the next row's cell on hitting enter button. Navigation work's only with Tab button. How can i achieve desired result?

Is it possible to put data in the group header row, that isn't a part of the group?

I'm trying to use the RadGridView control for a WPF app (.NET 4.5). We've got a WCF service which runs a SQL query that looks at 2 tables in 1 database, and a third table in a secod database. The WCF service returns all of the results. The results include things like client number, case number, client's first and last names, date of birth, etc. We want to group the results by the client number, and that's easily done, but what we also want to do is display things like the client's first and last name, DOB, etc in the group header. Clearly, however, we don't want to group by the client's name, or DOB, etc. Only by the client number (the case number does change from one record to the next and some other fields do too, but aren't relevant to this discussion).

My question is a simple one, is it possible to put into the group header data that isn't a part of the group, like client's first and last name, DOB, etc? If so, how is that done. But if not, then how do we get the data in a way that the RadGridView will display it the way we need it displayed?

Issue with Exporting to Word

Hi,
I'm trying to use the GridView export to *whatever format*, and they all seem to work fine, except the export to Text. I tried using your demo online, and that gave me the same problem. When I save it, it saves as a .doc (I also tried with .docx), and then the file is naturally saved to my drive as that format. However when I open it, it tries to open in a browser (in my case IE), and throws an error and won't open. First of all, have you seen this before, and secondly why would it try to open in a browser? Shouldn't it just be Word?

Thanks,
Ryan

Default readonly editortemplate

Hi,

Can I override default editortemplate for properties?

I would like to use TextBox instead of TextBlock on properties, that are readonly (like in VS2012
I'm using autogenerated scenarios.

I guess setting editortemplate explicitly in propertydefinition will override editortemplateselector logic as well, which is not desired behaviour
