Hi,

I'm using VS2008 and Telerik V2010.3.1314.35 and I have a RadGridView with Date, Time and string column and I don't know why but when I try to copy cell content of cell type other that string, I have an error...

When I copy cell content of a data cell type other than string, "e.Value" always equal null....

How I can handle any cell data type when I try to copy a cell content???

Thank's

private void SignCtxVisitsGrid_CopyingCellClipboardContent(object sender, GridViewCellClipboardEventArgs e)

{

e.Cancel =

false;

if (mSelectedCell != null && mSelectedCell.Column == e.Cell.Column)

{

try

{

System.Windows.Forms.

Clipboard.SetText(e.Value as string);

}

catch (Exception exc)

{

}

else

{

e.Cancel =

true;

}

How to set Variants when using MVVM

Basing my implementation on your RadRibbonView MVVM example I need to be able to set the variants. But this does not appear to be possible. If it is can you please supply an example where the groups are derrived from the ViewModel.

Thanks

DescriptionPanel

As the beta example is not that detailed, I have to ask:

Is it possible to set the initial height of the description panel and where can I switch on, that the user can change the height of the description panel?

Strange behaviour of minimized Icons

Edit: Title should be "Strange behaviour of minimized ITEMS" (not icons, but I can't change the Title)

Dear Support,

I'm just testing your controls because the Infragistics-Suite seems not to support MVVM in any way.
Your OutlookBar works great, but I have an issue/question about the "Caption/Header/Text" of minimizedItems.
Please take a look at following XAML

<telerik:RadOutlookBar QuickStart:ThemeAwareBackgroundBehavior.IsEnabled="True" telerik:Theming.Theme="Office_Blue" ItemsSource="{Binding OutlookEntries}" Height="234" HorizontalAlignment="Stretch" Margin="211,6,160,31" Name="RadOutlookBar1" VerticalAlignment="Stretch" Width="229">

<telerik:RadOutlookBar.Resources>

<Style TargetType="{x:Type telerik:RadOutlookBarItem}">

<Setter Property="Header" Value="{Binding Header}"/>

<Setter Property="SmallIcon" Value="{Binding SmallImage}"/>

<Setter Property="Title" Value="{Binding Header}"/>

<Setter Property="Icon" Value="{Binding LargeImage}"/>

</Style>

</telerik:RadOutlookBar.Resources>

</telerik:RadOutlookBar>

The Items are shown correctly. But if I'm using the slider in order to minimize the Items, the SmallIcon together with the ClassName will be shown at each "minimizedItem" in the outlookbar at the bottom. I don't understand why.

I have seen your MVVM-Binding-Sample in which you used ItemMinimizedTemplate

<telerik:RadOutlookBar.ItemMinimizedTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal">

<TextBlock Text={Binding Header}/>

</StackPanel>

</DataTemplate>

</telerik:RadOutlookBar.ItemMinimizedTemplate>

I could use this DataTemplage and delete the TextBlock inside the StackPanel. Then only the Icon will be shown within minimized Items.
But it seems more clean for me with my code above, instead of retemplating ItemMinimizedTemplate, ItemTemplate, HeaderTemplate etc. The OutlookBar is bound to a CollectionView calles "OutlookEntries" which contains a simple Class with Strings as Header and ImageSources as Icons.

Any hints would be appreciated.

I need to show the search point by adding one pinpoint. do you have some custom search example for openstreetmap?

Please provide some sample code for the openstreetmap.

RadRichTextBox error

Good evening,

I'm keep getting the following error whilst trying to use the WPF RadRichTextBox in the "Word Processing" configuration in VS2010 VB.net 4. It's the latest WPF tools (version 0419).
I dragged and dropped the RichTextBox into my designer window grid and then followed the step by step process. All works and looks fine until I run the app in debug mode.

FileNotFoundException was unhandled
Could not load file or assembly 'System.ComponentModel.Composition, Version=2009.7.8.0, Culture=neutral, PublicKeyToken=13e5ffd4e05db186' or one of its dependencies. The system cannot find the file specified.

System.Windows.Data Error: 40 : BindingExpression path error: 'CaptionButtonsReservedWidth' property not found on 'object' ''MainWindow' (Name='')'. BindingExpression:Path=CaptionButtonsReservedWidth; DataItem='MainWindow' (Name=''); target element is 'ContentControl' (Name='windowButtonPlaceHolder'); target property is 'Width' (type 'Double')

A first chance exception of type 'System.IO.FileNotFoundException' occurred in Telerik.Windows.Documents.dll

When the app runs a dialog window opens trying to find a RadDictionary.cs file.

I have uninstalled and re-installed the Telerik WPF tools and it hasn't solved the problem.

It did originally work but now for some reason it doesn't anymore.

Thank you for your time,

Rob

Save Command

Short question. How can I intercept the save command, i.e. not show the save dialog, but write the image into a database? I tried the ImageToolViewModel, but in there are only tools defined... no save button.

Edit: Found the ImageEditorRoutedCommands.Save
is there a (telerik) best practice to override the command?

Another Edit: Ok there's myImageEditorUI.ImageEditor.CommandBindings ... where I can add a command binding to the save command and set handled = true ... however, ImageEditor seems to be (always) null, even after an image has been loaded.

Thanks for your advice!
