User configuration with MVVM Prism

We are using MVVM Prism for our application, and there are three assemblies in our project.
myWPF (general stuffs and user configuration)
myApp (knows only myWPF)
myModules (knows only myWPF)

Does Telerik provide any user configuration object for storing/retrieving user preferences such as application theme, docking layout, default selection of a control in a module, and etc...

Thanks

RadGridView Performances Issue with RadDocking Q3 2011

Hi,

We are using some RadGridView in multiple RadDocking Panes.
Thoses grids have over 1000 items and we got an serious performance issue when switch between panes (hosted in DocumentHost). It takes about 1-2sec before displaying the pane.

I don't understand since in Q2 2011 it works pretty much. But now in Q3 2011 it's really slow.

The grid is quite simple :

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="Auto"/>

<RowDefinition Height="500"/>

</Grid.RowDefinitions>

<GroupBox Header="Recherche" Margin="5">

<StackPanel Orientation="Horizontal">

<TextBlock Text="Filtre" Margin="5"/>

<TextBox x:Name="txtFilter" Margin="5" Width="200"/>

</StackPanel>

</GroupBox>

<telerik:RadGridView Grid.Row="1" Height="500" ShowGroupPanel="False" IsFilteringAllowed="False" CanUserFreezeColumns="False" CanUserReorderColumns="False" ValidatesOnDataErrors="None" FilterTextBox:TextBoxFilterBehavior.TextBox="{Binding ElementName=txtFilter}" SelectedItem="{Binding SelectedItem}" IsReadOnly="True" RowIndicatorVisibility="Collapsed" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" ItemsSource="{Binding ItemList}" AutoGenerateColumns="False">

<i:Interaction.Triggers>

<i:EventTrigger EventName="MouseDoubleClick" >

<ei:CallMethodAction TargetObject="{Binding}" MethodName="EditCommand"/>

</i:EventTrigger>

</i:Interaction.Triggers>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Width="100" Header="Code" DataMemberBinding="{Binding Code}" UniqueName="Code"/>

<telerik:GridViewDataColumn Width="450" Header="Désignation Longue" DataMemberBinding="{Binding LongName}"/>

<telerik:GridViewCheckBoxColumn Width="80" Header="Bloqué" DataMemberBinding="{Binding IsLocked}" UniqueName="IsLocked"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

I've tested to remove the GridViewCheckBoxColumn, without luck.

When me application window is sized to the minimum in order to display only 1 row in the grid, it's really fast, but in full screen (displaying about 30 items visible) it's really slow...

Any help ?

Thanks.

Control to View OpenOffice/Powerpoint Slides?

Hi,

I'm wondering whether there is such a Control in the WPF suite to enable me to view powerpoint / openoffice impress slideshows in my WPF application. If not, does anyone has any suggestions how to go about doing this within my application, rather than spawning the powerpoint viewer as a separate full screen application? Thanks for your help.

Using a bog standard ListView, this was performing just fine - but now I am having UI hangs while scrolling (when scrollmode was realtime) and I get a black background inside the window border while resizing..

What am I missing?

Need help navigating the documentation

Hello, I have been poking around the documentation, trying to find out if "ShowDistinctFilters" does what I want..
However, all I am able to find is "Gets or sets a value indicating whether this column will show distinct filters.".
That is taken from http://www.telerik.com/help/wpf/p_telerik_windows_controls_gridviewcolumn_showdistinctfilters.html

Is there a more helpful documentation available somewhere I am not finding?

What I want, by the way, is making a DateTime column not show every single time that is listed in the column with a checkbox, but still give the user the ability to filter using a date/time picker (from-to)
