Everything that I've tried results in a crash, with the exception being: Unable to cast object of type 'Telerik.Windows.Documents.Model.HyperlinkRangeEnd' to type 'Telerik.Windows.Documents.Model.Span'.  The two commented out sections were previous attempts at adding the hyperlinked image to the document at the current caret position.

I want to print two pages per sheet .Because I have one GridView and only three columns are available in the GridView. So remaining part of the page are unuseful.
so that I set  PrintDialog.PrintTicket.PagesPerSheet = 2 and PrintDialog.PrintQueue.DefaultPrintTicket.PagesPerSheet = 2. But its not working. And I am using following code for the Printing.


public static void Print(this GridViewDataControl source, bool showDialog, bool p_IsLandscape = true)
        {
            try
            {
                PrintDialog _PrintDialog = new PrintDialog();
                _PrintDialog.PrintQueue = LocalPrintServer.GetDefaultPrintQueue();
                _PrintDialog.PrintTicket = _PrintDialog.PrintQueue.DefaultPrintTicket;


                // Updated By Bharat Mendapara | Date : 11/03/2014
                //Reason SDPLAN-58 (DPA022 - Diagram Objects printing).
                if (p_IsLandscape)
                    _PrintDialog.PrintTicket.PageOrientation = PageOrientation.Landscape;
                else
                {
                    _PrintDialog.PrintTicket.PageOrientation = PageOrientation.Portrait;
                    _PrintDialog.PrintTicket.PagesPerSheet = 2;
                    _PrintDialog.PrintQueue.DefaultPrintTicket.PagesPerSheet = 2;
                }

                bool? dialogResult = showDialog ? _PrintDialog.ShowDialog() : true;

                if (dialogResult == true)
                {
                    DocumentViewer viewer = new DocumentViewer();
                    viewer.Document = ToFixedDocument(ToPrintFriendlyGrid(source), _PrintDialog);
                    _PrintDialog.PrintDocument(viewer.Document.DocumentPaginator, null);
                }
            }
            catch
            {
            }
        }

        {
            PrintCapabilities capabilities = dialog.PrintQueue.GetPrintCapabilities(dialog.PrintTicket);
            FixedDocument fixedDocument = new FixedDocument();

            element.Measure(new Size(double.PositiveInfinity, double.PositiveInfinity));

            Size pageSize = new Size(element.DesiredSize.Width, dialog.PrintableAreaHeight);

Hello,

I am trying to put a RadHeatMap into my RadMap. Is it possible to put a RadHeatMap in an information layer? Is that the best way to do it, or is there a better way? How would I put a RadHeatMap inside of my RadMap so that it moves and zooms as if it were part of the map? I don't want labels or anything fancy on my RadHeatMap. I'm just looking to put a very simple, square, grid-like heat map on my RadMap.

I have MapPinPoints in an information layer already and I would like to be able to tell which "cell" of my RadHeatMap each PinPoint is from. Is there any way to do this?

Thanks in advance,
Liam

Hello,

I'm working on an app which needs to list many items (kind of 50 000 sometimes) with a custom items template.
Everything is working fine while controlling with the mouse, but it's buggy with a touch screen. In order to be able to click on a button or a checkbox inside any of the items, you need to swipe somewhere on the main list before.

Here is a part of my code : (scj: controls are derived from telerik: controls with only one or two more properties)

my XAML :

resource file - style :

resource file - data template :

I have tried on a :
-Win7 with mouse, everything is OK (smooth scrolling, clicking on the buttons, on the checkbox...)
-Win7 with touch, impossible to click on any button nor checkbox of an item (button gets focused but no event raised, checkbox get focused but not checked, but smooth scolling the list works fine)
-Win8 with touch, I need to swipe before clicking, or checking a box on an item (but smooth scolling works fine)

I haven't modified any touch behavior  at all. I need virtualization because of the number of items to load (from 15 to 50 000), and I need the control to act like an android app with touch smooth scrolling.

The screencapture shows the final window. Each light gray item contains a picture, 2 buttons and a checkbox.

My question is, is there a way to make it work with a touch screen, and how ?

Thank you for reading :)

Hello.

I need to implement a chart with vertical lines and labels, as I understand it can be implemented using annotations.
As I can see from examples, it should look lile this:

But information for annotations I get from ViewModel. And I don't see a way how to bind my collections from ViewModel to Annotations collection. Is it possible? I mean something like this:

I found a workaround, to add annotations in a code-behind class of the view:
But seems it is not a true way.

I'm upgrading my telerik version, I need to find the index of the first visible row.  I used to do this:

Hi there, 
I need to place button into PropertyDefinition, and bind Command on click this button, which opening window,
How  can I do that?

Hi,

I'm trying to hide the top row (where the group button, sort button and search box are located).

I have set both the SearchBoxVisibility and SortAndGroupButtonsVisibility to false so all the above controls are hidden.

The result I have is an empty grey row with nothing inside it.

I want to hide that row and recover that real-estate for the grid itself.

I wasn't able to locate a property that does that and couldn't find an answer searching this forum (and google).

I would appreciate your help on this matter.

Thanks in advance.

Hi,

I have an application in which we haven't defined width and height for the windows or controls, instead we used Auto and * mostly for control size. To make the screen design fluid and support multiple display sizes.

I am facing an issue in showing a horizontal scroll bar for my RadGridView which is placed inside panel with no width and height defined.  I have defined Auto and * as the Column's width in gridview. 

My requirement is that a scroll bar should appear when the content of the grid take more space than the space available on the screen. But currently the content is clipped and no scrollbar appears (see screenshot attached).

The code I am using is:



Please help me getting a scroll bar.
Thanks.
