I have a simple RadPdfViewer declared in my UserControl:

    <t:RadPdfViewer Grid.Row="1" x:Name="PdfViewer" DocumentSource="{Binding Uri}" 
                    PreviewKeyDown="PdfViewer_OnPreviewKeyDown"
                    DocumentChanged="PdfViewer_OnDocumentChanged"/>

Randomly (although it appears that this exception does not occur if I wait for the current document to be fully rendered and the progress indicator to be removed by the RadPdfViewer) when "Uri" property in my VM (which is a simple string property) is changed to new Uri of some pdf file I get ObjectDisposedException with "Cannot access a closed file." message.

StackTrace:

   at System.IO.__Error.FileNotOpen()
   at System.IO.FileStream.get_Position()
   at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfReader.Readers.PdfReaderBase.ReadInternal() in c:\TB\117\WPF_Scrum\Release_WPF\Sources\Development\Documents\Fixed\Core\FormatProviders\Pdf\PdfReader\Readers\PdfReaderBase.cs:line 174

Could you please take a look?

Hi all,

i have got an issue in using drag and drop functionality in combination with autoscrolling in GridView.
I must be able to select a cell in gridview and the target cell can only be made visible with scrolling up (may be the target cell is on the upper side of grid and source cell is contained in last row).
So, if I try to pick up the source cell drag and drop may be initialized and if i move mouse cursor up gridview does not autoscroll up if i come closer and closer to the also visible column headers.

Is there any way to implement it? If yes it would be very very cool if someone can post a solution for it. :)

We use RadGridview in combination with the  DragDropManage (without "and").

I have a gridview where the users select which columns are visible or hidden.  Is there a simple way to save the user's column choices locally and reload them the next time they access the application?

Thank you.

When using RadGridView, I load the ItemsSource, but the Items are empty. Meaning that when I try to read foreach( item in radgridview.Items) it will not pick any item.

If I load the radGridView item by item using x.Items.add(), the ItemsSource is null

It was my expectation that Items and ItemSource should be linked. How can I load a bulk using ItemsSource but then use the items, or load item per item, but extract all the content using ItemSource.

Using the WPF RadRichTextBox with the built in spell-checker and am running into issues where possessives are marked as misspelled.

For example

• supervisor is marked correct as a singular
• supervisors is marked correct as a plural
• supervisor's is marked incorrect
• supervisors' is marked correct

Hi,

I have a RadDocking control, DragDropMode="Deferred".
Attempts to dock a pane to the root compass fail if the cursor is still within the dragged pane.


Steps to replicate:

 1. Attempt to dock Pane 2 to the right of the Root Compass (see img2): Fail
 2. Attempt to dock Pane 3 to the bottom of the Root Compass (hover the mouse such that the compass for Pane 3 appears. see img3): Fail
3. Attempt to dock Pane 3 to the bottom of the Root Compass (hover the mouse such that the compass for Pane 1 appears): Success

Any ideas? Thanks!

Hi,

I'm new to WPF development, and am wanting to see if it is possible to bind properties of the RadGridView (such as CanUserSortColumns) to application settings?  i.e. I have defined a set of application settings such as AllowSorting, AllowGrouping etc, and it seems I should be able to bind the relevant properties on RadGridView to these settings, but I don't know how.

Any help appreciated,
Neil.

Hi,

I like to use the button for a Hyperlink Button. Everything looks fine if I´m setting the IsBackgroundVisible Property to false. 

But it´s not possible for me to change the mouse if the user has the mouse over the button. At this moment I like to show a Hand mouse courser.

Thanks for your help.
