Problem upgrading property grid to latest version

[HDC]

I am using RadPropertyGrid in our project.

It was working fine in our application until we upgraded to version 2012.1.215.1050. Now i'm getting following error:

"ItemPropertyInfo descriptor is not supported"

This is the code that i'm using

PropertyDefinition pdef = new PropertyDefinition();
           if ((attrib as PropertyEditorAttribute).PropertyEditor != PropertyEditorEnum.TelerikDefault)
           {
               pdef = new PropertyDefinition(
               new ItemPropertyInfo(e.PropertyDefinition.DisplayName, typeof(string), null));
           }
           else if ((attrib as PropertyEditorAttribute).Name == "Font Style")
           {
               pdef = new PropertyDefinition(
               new ItemPropertyInfo(e.PropertyDefinition.DisplayName, typeof(FontStyles), null));
           }

           pdef.GroupName = group;
           pdef.DisplayName = name;
           pdef.Description = description;
           pdef.EditorTemplate = dataeditor;
           propertyGrid.PropertyDefinitions.Add(pdef);

I cannot find any indication in the documentation that something has changed. What is the equivalent for this code or how do i fix this?

I fugured out the problem is caused by the NULL value in the code:

pdef = new PropertyDefinition(

new ItemPropertyInfo(e.PropertyDefinition.DisplayName, typeof(FontStyles), null));

The <null> is not accepted anymore (it is the cause of the error), but i don't know what to put there and the documentation is quite useless concerning this particular topic.

Can anyone tell me how this "object" looks like? 

Best Regards,

Hi Peter,

You need to define your property definition as follows:

PropertyDefinition pdef = new PropertyDefinition();
        pdef.Binding = new Binding("LastName");
        pdef.DisplayName = "Last Name";
        pdef.Description = "Last Name";
        this.myPropertyGrid.PropertyDefinitions.Add(pdef);

You might try using the other constructor for PropertyDefinition and use PropertyInfo for a descriptor for example. However, my recommendation would be to follow the approach illustrated above with the default constructor. 

All the best,
