Is it possibble to set the DefaultImgSrc of a treeview item to a System.Windows,Controls.Image type? Basically I want to do the following.

 

RadTreeViewItem node = new RadTreeViewItem();

 

 

Image iconImage = new Image();

 

 

BitmapImage img = new BitmapImage(new Uri(uriString, UriKind.Relative));

 

iconImage.Source = img;

 

 

ToolTipService.SetToolTip(iconImage,"Test tooltip");

 

node.DefaultImageSrc = img;

Thanks,
Swayam

Hi SWAYAM KAR,

You cannot set the DefaultImageSrc to System.Windows.Controls Image class since it represents a control that displays an image.

Unfortunately, there is also a known bug in the RadTreeView control and for now the DefaultImageSrc cannot be set to an object of type BitmapImage. We are currently working on this issue and we will do our best to fix it as soon as possible.

However, for now you can either try this from code-behind:
string uriString = "icon.png";
node.DefaultImageSrc = uriString;

or you can take a look at the example I attached and follow the suggested approach in it.

Please let me know if either of this suggestions work for you.

If not, can you please elaborate on the scenario you want to implement, so that we can suggest the best suited approach for you.
