I love the examples you have showing how you can group by a category. Is it possible to add multiple categories to an appointment and group by it? For example, lets say using your TV Schedule example, a show might be Sports and Documentary. So when Grouping, I would like to see the Appointment come up in both Sports and Documentary. Obviously, I have to be able to select multiple categories. But how to group by them as well? Would be a HUGE Help if you could give me some direction.

WPF - Telerik schedule view recursive block creation with shift key

Hi,

I tried to create a schedule view grid with recursive block feature.

For Radscheduleview - EnableSimpleReccurrenceRendering="True" RecurringSelectionModifier="Shift"
Active view definition - <telerik:WeekViewDefinition Orientation="Vertical" GroupHeaderDateStringFormat="{}{0:yyyy MMMM dd}" TimerulerMajorTickStringFormat="{}{0:%h t}" DayStartTime="05:00" DayEndTime="05:00" VisibleDays="30"/>

I am able to create recursive blocks in all the areas, except last row 04 30 to 05 00 AM in the grid.
If i set grid start and end as 05 00 AM to 04:59 AM then it is working fine.

Pls suggest me the way to achieve this.

href of <a> anchor tags is getting stripped out

The problem that I'm encountering is the xhtml that I'm passing in to the telerik RadRichTextBox is being modified by removing parts of the <a> anchor tag. Specifically, the href and a custom property (not shown in my example). I've include the xhtml that I send into the editor and what I get out from the editor. The links in the editor do not work so I know that the link tag is being stripped when I set the xhtml to the document.

Here is the Get/Set that I use.

public string HtmlText

{

get

{

string xhtml = new HtmlFormatProvider().Export(Document);

return xhtml;

}

set

{

Trace.WriteLine(xhtml);

Document = new HtmlFormatProvider().Import(xhtml);

Trace.WriteLine(new HtmlFormatProvider().Export(Document));

}

xhmtl from the first Trace output (href="http://www.google.com" is there)

Focus stays on right hand side instead of being on left hand side

I have a RadMaskedDateTimeInput for DateTime where I am displaying Time. Now when I click on inbuilt Clear Button, the focus stays on right most side.
Is there a way to get focus on left most side, as it was in the previous version (2013.2.724.40), but my current installed version is 2013.3.1204.40.
Any help will be much more appreciated.

Thanks

Call methods from ViewModel

Let's suppose I have a RadPaneGroup in a WPF view.

Now I want to do this:

var x = new RadPane();

myRadPaneGroup.AddItem(x);

This must be done in the ViewModel NOT code behind.

How do we accomplish that?

How to update RowDetails after editing a row cell value?

Hi,

I'm pretty new to Telerik WPF programming, so please forgive me any dumb questions.

I have a GridView control which displays its data through a ValueConverter which retrieves the data from a complex data structure in memory. I use a DataTemplate which displays additional information from the complex data structure using the same ValueConverter.
This works just fine.
If I now edit a cell value in my GridView, the data gets correctly updated in my data structure, but the value displayed in RowDetails still shows the old value. Even if I close and reopen the RowDetails, the old value remains visible.
I guess this is because of this:
www.telerik.com/help/wpf/radgridview-row-details-programming.html
LoadingRowDetails - the LoadingRowDetails event is raised immediately after the FrameworkElement has been loaded from the Row DetailsDataTemplate. It is raised the very first time the row details are about to be shown. Once this event has been fired, it will never fire again for that row. However, if the row is recycled and then realized, it starts its "life" again, this event will be fired again the first time the details are about to be shown.

Do I need to manually fire the LoadingRowDetails event to get the data updated in the RowDetails? Any other thoughts how to do this? Any code examples or internet pointers how to do this?

Thanks for your help.

Best regards,
Markus

DragCue On Native Dragging

I have dragging working functionally (dragging from inside the application and from an external application), but I cannot for the life of me get the DragCue to show up when dragging from outside the program (it works fine when dragging items around the same application). What I realized is the DragCue is null inside the DropInfo event when dragging items from external programs. I tried to hook the DragInfo event (as shown in the WPF GridView Reorder Rows sample) to manually create the DragCue item, but this event is never fired for externally dragged items. As a last attempt, in the DropInfo event I created a DragCue item if it is null, but it is never displayed.

Is there a way to show the DragCue for externally dragged items?

When Adding a new row, how to set the edit focus in row

Maybe I'm missing something very simple, but I can't seem to set the focus to a cell after I've already entered a row.

If add a row and use telerik:RadGridViewCommands.BeginInsert, the first time it works great, and puts the cursor on the 1st editable cell.
But after I insert it, and clicks the add again, it puts the cursor on the last column, or the column I last used in my edit.

I tried to set the focus on AddingNewDataItem trigger, but that doesn't seem to work, or I'm doing it wrong.
Should I just do:
myGrid.Columns[1].Focus(); //1 is the column I want, the first is a delete button
because the row isn't in edit mode yet.
BeginningEdit doesn't work because that applies to any cell.

Exporting PagedData - PageIndex cannot be negative when PageSize is positive

Hi all,

I am using RadDataPager and GridView to export data spans multiple pages. I followed the demo here:
http://demos.telerik.com/silverlight/#GridView/ExportingPagedData

No errors are reported in Visual Studio. I compile and run the application, and click on my "export" button - at the prompt, I enter a file name for the .xls and hit "save." Then I get the following error:
                            An unhandled exception ("Unhandled Error in Silverlight Application
                            Code: 4004
                            Category: ManagedRuntimeError
                            Message: System.ArgumentOutOfRangeException: PageIndex cannot be negative when PageSize is positive.
Where would the PageIndex set to a negative number? I'm overlooking something obvious - a value I should have set somewhere or something - but I can't find it. I followed the demo closely and it seemed to be working for me until I tried to export the file.

Any ideas? I'm using Telerik Reporting Q3 and Visual Studio 2010. Thanks!
