Cannot perform this operation when hosted in browser.

Hi I'm using 2013-Q1.
I've the following xaml:

<telerik:RadRibbonView TitleBarVisibility="Collapsed" telerik:StyleManager.Theme="Windows8" telerik:KeyTipService.IsKeyTipsEnabled="True"

MinimizeButtonVisibility="Visible">

<telerik:RadRibbonView.Backstage>

<telerik:RadRibbonBackstage>

</telerik:RadRibbonBackstage>

</telerik:RadRibbonView.Backstage>

</telerik:RadRibbonView>

when I click application button I got the "Cannot perform this operation when hosted in browser." exception.

Am I doing something wrong ?

Thank you.

Multi-touch support for panning and zooming in Map

Hi,

According to this webpage http://www.telerik.com/help/wpf/radmap-overview.html, your map control has multi-touch support for panning and zooming. However, it seems that by default this is not enabled when using the control on Windows 7. In other locations it is said that Silverlight has multi-touch support, but the WPF version does not. Can you please clarify? We are on a deadline so I hope we don't have to spend time to create a workaround for this.

Thank you for your answer,
Lex

Broken intellisense after adding TileView and RadialGauge to the project

No errors pop during the installation of Telerik WPF suite that I remember.

I noticed, after installing the Telerik controls and adding a few of the controls to my WPF project, intellisense stopped working.

I am using VS2012 Ultimate, and intellisense works for other (small test projects) with Telerik controls in it.

I verified, edits I've got in my project from the last check-in are just Telerik controls. Any known issues that anyone have to share about this weirdness? Much appreciated!!

Rad Menu + Role Management

Hi,

I use the RadMenu for wpf and it's great. Now I want to set some menu items "IsEnabled = false;" based on
a user-role management.

On login the user gets a role, based on this role some menu-items a enabled some are not. How do I solve this?

The main problem is, that I want to load the rolls just once and use these rolls everywhere in my application!?

Thanks
Best Regards
Rene

Detect when row is added in a filtered grid

I have a grid with filtering applied on various columns. I want to alert the user whenever a new row is added to the grid, but I can't just observe the Items.CollectionChanged event, as many of these rows won't necessarily be displayed due to the active filtering. I only want to alert when a row has been added and is viewable in the grid (even if it's currently out of scroll view).

Is there an event that I can use, or method that I can check if a row is filtered or not?

Thanks.

ReadOnlyTemplate+CommandButtonsVisibility

Hello,
Im using the RadDataForm Control together with the RadGrid Control. They both are based on the same collection of type
QueryableCollectionView. The objects in the collection are class based objects, the class implements IEditableObject, INotifyPropertyChanged,IDataErrorInfo intrrfaces. My problem is that I want to hide the Commit and the Cancel button but only when
RadDataForm is in ReadOnlyMode, is this possible do this in other way than implementing my own buttons?

<telerik:RadDataForm.ReadOnlyTemplate>

<DataTemplate>

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="Auto"/>

</Grid.ColumnDefinitions>

<Label Grid.Row="0" Grid.Column="0" Width="40" Content="Key" IsTabStop="False" />

<Label Grid.Row="1" Grid.Column="0" Width="40" Content="Value" IsTabStop="False"/>

<TextBox Grid.Row="0" Grid.Column="1" Width="170" Height="23" Foreground="Black" Text="{Binding Key}" IsTabStop="False" IsEnabled="False" TextWrapping="Wrap" IsReadOnly="True" />

<TextBox Grid.Row="1" Grid.Column="1" Width="170" Height="23" Foreground="Black" Text="{Binding Value}" IsTabStop="False" TextWrapping="Wrap" IsEnabled="False" IsReadOnly="True" />

</Grid>

</DataTemplate>

</telerik:RadDataForm.ReadOnlyTemplate>

Also is it possible to scroll to the new added row of the grid when Im adding it using RadDataForms add button ?

Regards,

DataForm

Grid view columns reordering

Hi,

In my rad grid view i have set CanUserReorderColumns to true.But it doesn't work in some situations. Could you please tell us that where to drop the column in order to be dropped.

If i drag a column and drop it in half of the column part then sometimes it is dropped and sometimes it doesn't work.

Also there is one more requirement from our client, they want the reordering of column with some sliding effect like ( EX. in our windows -> go to my computer -> open details view then reorder columns , there is some visual indication of reordering .. see attached image file) .

Looking forward for your reply.

Which property of RadComboBox I can use to close RadComboBox popup?

Hi,

I have modified ControlTemplate of RadCombioBox to display RadGridView. I am facing an issue with this. When I click an item from ComboBox to select it the ComboBox is not collapsing. I want to close the ComboBox popup when use selects an item and selected item should be assign to SelectedValue property of ComboBox. FYI, I have place RadGridView under NonEditableTemplate (inside "PART_Popup" popup).

And also I have tried seting IsDropDownOpen property to false on SelectedItem property but is also not working. When I click outside ComboBox the popup closes but a yellow border displayed around ComboBox.

Hereby I have attached image which helps to understand requirement. Please have a look at it.

Please help to resolve issue.
