Is there a good way to disable the zoom animation that happens on the RadDiagram when I set the Zoom property on my diagram?
I want it to be instantaneous.

Thanks

Hi,
I want to create this behavior:

I want to be able to select only full lines, act on double click on the line -

currently I have 2 problems with this code:



1, when I double click inside the line - it selects the cell and not the line - I can only choose the line by clicking on the edge of the line.
    this code will return null: RecordType st = ((FrameworkElement)e.OriginalSource).DataContext as RecordType (unless I click on the edge)
2. when I click on the vertical scroll bar more than 2 times - it acts like selecting a cell ! - I need to interpreting clicking on scroll bar as clicking on the grid surface....

How can I fix this ?

Fairly new to MVVM and learing as I go.  A little stuck on the proper usage of

Telerik.Windows.Controls DelegateCommand

.  I have the below set up, which compiles, however I am more concerned with, whether, I am using it correctly.  I have searched the Online Doc for a while now and couldn't find any examples.

Particularly, I am confused as how I would use the CanSaveAuthorization, or the underlying CanExecute, and what I would do with the object parameter that is required.

Thanks,

    

This is the border of the RadPropertyGrid with Expression_DarkTheme :

I want to apply the same border at a Rectangle.

rect = new Rectangle();
rect.Stroke = Brushes.?;

But i don't know what brushes to use...

Thanks for your help !

Hi,

I know there are some limitations on pictures, encoding and other things, but would it be possible to show an error message saying it's can't load this pdf?  99% of the files I think will work, but if a client tries to use a file that doesn't load correctly I'd like it to give an error message and say to download the file instead.

Hi,

in my project I have a method who need parameters and one of them is an object that I want the persistence stream result.
When I call my method, the PersistenceError event handler was called when I try to use the SAVE method of the PersistenceManager and I get the following french error message: Nombre de paramètres incorrects.

Here is the way I call my method:

PersistenceStorage

 

.Persist(MainGrid, ref stream, PersistenceStorage.PersistenceAction.Save, out errMsg);

 

Here is my static object with my method:

static

 

public class PersistenceStorage

 

{

static public bool Persist(object pObject, ref Stream pStream, PersistenceAction pPersistenceAction, out string pErrorMessage)

 

{

mResult =

true;

 

pErrorMessage =

string.Empty;

 

 

PersistenceManager manager = new PersistenceManager();

 

manager.PersistenceError +=

new Telerik.Windows.Persistence.Events.PersistenceErrorEventHandler(manager_PersistenceError);

 

 

try

 

{

 

if (pPersistenceAction == PersistenceAction.Load)

 

{

 

if (pObject != null && pStream != null)

 

{

pStream.Position = 0L;

manager.Load(pObject, pStream);

}

 

else

 

{

mResult =

false;

 

}

}

 

else if (pPersistenceAction == PersistenceAction.Save)

 

{

 

if (pObject != null)

 

{

pStream = manager.Save(pObject);

}

 

else

 

{

mResult =

false;

 

}

}

}

 

catch

 

{

mResult =

false;

 

}

 

finally

 

{

manager.PersistenceError -=

new Telerik.Windows.Persistence.Events.PersistenceErrorEventHandler(manager_PersistenceError);

 

pErrorMessage = mErrorMessage;

}

 

return mResult;

 

}

 

static void manager_PersistenceError(object sender, Telerik.Windows.Persistence.Events.PersistenceErrorEventArgs e)

 

{

mErrorMessage = e.Exception.Message;

mResult =

false;

 

}

 

public enum PersistenceAction { Load, Save }

 

 

static private string mErrorMessage;

 

 

static private bool mResult;

 

}

Hi

I want to be able to drop a file from the desktop on to an existing row in a RadGridView. (The event handler will then do something with the file and manipulate the data for that specific row, but that isn't relevant for this discussion.)

Can anybody shed some light on how this can be achieved? I have managed to drop a file on the the RadGridView component itsself, but that's not what I want. I need to be able to drop on a specific row (or preferably have the option to drop on the RadGridView also if it doesn't conflict).

I am finding the Telerik documentation about drag and drop (using DragDropManager) hard to figure out since some of the examples just don't work (http://www.telerik.com/help/wpf/dragdropmanager-getting-started.html) and many of the example projects referred to in prior forum solutions seem to use the RadDragAndDropManager which I understand is soon to be obsoleted.

Anybody?
