Hi all of you,

I'm using this control under trial license. I'm trying to do a very simple binding but it doesn't work at all:

xaml header:

Here you can see the reference to one of my RESX files (I've got one for English and another one for Spanish where every key is named alike.
Names of resources files:

MasterGIT.resx and MasterGIT.en.resx

This line uses one RESX under criteria language:

     ResxExtension.DefaultResxName="GIT_CuadroMando.MasterGIT" Language="{UICulture}"



xaml stuff:

Code-behind:




Thanks in advance for any hint or advice,

i have used a RadTileView,

hi there,

I would need more power with this control. I mean, being able to show more buttons would be great. I wonder, is it possible?
My aim is display a button where the user can save the images and their later treatment against my RDBMS (Sql2k8)

Also I would fancy show a Context Menu on the bare surface of the control.

Telerik 2013 Q1 NET 4.5 for WPF.

Thanks in advance,

Hi,

i have a GridView binded to an observable collection of "items" and its SelectedItem property binded to an item in the ViewModel.

Example to explain the behavior that I want to avoid:

I have 3 items in the collection and in the grid I've selected the second row, corresponding to the second element of the collection.
If I add a new element in the collection, the gridview automatically adds a new row for it (and thats ok) and select this new row (which is not ok for me, in this case I want to keep the selection on the second row)

Any idea to achieve this?

Thanks

I'm trying to figure out how to use a Telerik ListBox control for an application that I'm writing. For some reason I can't view any of the Telerik demos (they're all timing out on me), and so I've been searching around this site for other help. I came across this page on drag-and-drop for the ListBox, and it looks really promising. However, in reading through the code on the page I came across their ProductToOrderConverter class. It inherits (or implements, I'm not sure which) from something called a DataConverter. What is that?? Even on this site I'm having a hard time finding any documentation on what the dataconverter class/interface is.

Is there a built in method (or plans to implement) to lock tiles assigned to a particular group from being dragged to another group?  For instance, say I have a series of tiles associated with the group Music, and another series of tiles associated with the group Movies.  I would like to prevent these tiles from being moved between groups.
