Hi,

We are using RadRibbonView that contains RibbonTab with a number of Ribbon Groups. I want to show a textbox (for search functionality) and I want to be aligned to the right of the ribbon view. If I added this textbox inside a spate Ribbon Group, then that group is appended to the rest of the group, and not aligned to the right. Also, I tried to create a grid inside the Ribbon tab and set all the group on one column, and then have that textbox on the second column, but apparently Ribbon Tabs doesn’t accept Grid inside, I got a run time error.

Any idea how I can achieve this?!

Regards

Behaviors broken after Q3 release

In our application we use attached behaviors on RadControls in a number of places to avoid code-behind (mvvm pattern). These are used for some custom validation logic in grids, automatic significant digits displays on NumericUpDowns, and many others. After updating to the latest release (2011.3.1116.35) the following error occurs on all of these behaviors:

Cannot add content of type 'Behaviors.DynamicDecimalDigitsBehavior' to an object of type 'System.Windows.Interactivity.BehaviorCollection'. Error at object 'Behaviors.DynamicDecimalDigitsBehavior' in markup file 'setdatarenderingpropertiesview.xaml' Line 270 Position 22.

The project is built in .Net 3.5, and as such we reference System.Windows.Interactivity version 3.5.0.0.

Does this make any sense to try with this control?

Hello,

I am prototyping a user interface. Basic slimmed down requirements are that I have a list of items on left side of page for the user to select. On the right side of the list there will be a large view that contains information about the item that was selected in the list. I have put together UI like this many times and also have used many telerik controls in our applications. The TileView caught my eye for this one, thinking that I may be able to have something that serves the purpose and provides a bit of modern look and feel rather than just a list.

I practice MVVM and use prism with unity injection.

So what I am looking to get from this control is a templated list of items on left side in a single column. When one is selected a templated view of the information related to the selection animates (maximizes) over to the right. I do not want to ever have the items in a tiled view with several columnns and I do not want to have to Maximize in order to see information on the right side.

Can you let me know if I am going to be able to achieve this functionality with the control? In addition, if this is possible, could you provide a simple example for me to download?

Thanks,

Jason Munger

EF and IEditableObject

I have a DataForm that I load via EF. In order to support "Edits", I need to implement the IEditableObject interface but I can't get it to work. I am almost certain I am not the first one trying to do this so if anyone can point me in the right direction would be great.

Thanks in advance.

Ambigious type reference error & FilteringControl style

I just added a style to my app (in appStyles.xaml) to hide the gridview distinct filter. The style is working but in design view of pages & windows i get the following errors:

This is what the resource declarations in the appStyles.xaml are:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<br>    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"<

br> xmlns:telerikGrid="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"<br

>    xmlns:Telerik_Windows_Controls_MaskedTextBox="clr-namespace:Telerik.Windows.Controls.MaskedTextBox;assembly=Telerik.Windows.Controls.Input"  >

Here's how i'm the style for the FilteringControl:

<Style TargetType="{x:Type telerik:FilteringControl}" > <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type telerik:FilteringControl}"> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="1" Margin="{TemplateBinding Margin}"> <Border BorderBrush="White" BorderThickness="1" Background="{TemplateBinding Background}"> <Grid> <StackPanel HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" MaxWidth="350" Margin="{TemplateBinding Padding}" MinWidth="200" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> <StackPanel x:Name="PART_DistinctFilter" Visibility="{TemplateBinding DistinctFiltersVisibility}"> <CheckBox x:Name="PART_SelectAllCheckBox" Visibility="Collapsed" Content="Select All" IsChecked="{Binding SelectAll, Mode=TwoWay}" Margin="0,2" telerik:LocalizationManager.ResourceKey="GridViewFilterSelectAll"> <telerik:StyleManager.Theme> <telerik:MetroTheme /> </telerik:StyleManager.Theme> </CheckBox> <ListBox x:Name="PART_DistinctValuesList" ItemsSource="{Binding DistinctValues}" ScrollViewer.HorizontalScrollBarVisibility="Auto"

Not sure if i need to qualify the FilteringControl style with something or add another xmlns reference to the styles. Thanks

TextBox apply default Theme

Hello,
I read many post in this forum, but still not have answer.

How to apply current telerik theme to TextBox?
So no hardcoded theme but current theme.

We have function like this:

internal static void ApplyConfiguredTheme()

{

switch (GetConfiguredTheme())

{

case ThemeEnum.Black:

StyleManager.ApplicationTheme = new Office_BlackTheme();

break;

case ThemeEnum.Blue:

StyleManager.ApplicationTheme = new Office_BlueTheme();

break;

case ThemeEnum.Silver:

StyleManager.ApplicationTheme = new Office_SilverTheme();
