get row clicked on from OnCommand client handler

I have a client side event handler for OnCommand. How can I get the index of the row that caused the OnCommand event to be fired. In my case I have a GridButtonColumn of type ImageButton. Clicking the image for an item in the row causes the OnCommand to fire. I need to know which row was clicked.

Editor applies a wrong style to the row after clicking Insert Row Below

I have the following scenario:

1. Insert a table on the page http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx

2. Apply the “telerik-reTable-2” style from the Table Properties

3. right-mouse-click on any cell of the table and select Insert Row Below (also, it may be above)

Result:

The row has some style, but the style of the table in general becomes different from “telerik-reTable-2” (ActualResult.png attached).

Expected Result:

The table has the style, that was previously selected – “telerik-reTable-2” (ExpectedResult.png attached).

Hierarchy, binding to object without ID fields

So I'm trying to use a RadGrid for displaying an object with nested Lists as properties. I have it in a user control so I'm declaring RadGrid in code-behind. The object is passed in through the user control's constructor, all of the data is contained in the object, there is no need for any lazy loading. The object is retrieved from MongoDB so there are no identity fields at any of the levels in the hierarchy (other than the database _id at the very top). So when looking at the demo "Grid - Creating Hierarchy Programmatically", I get stuck at creating GridRelationFields because, as far as my data is concerned, relations aren't necessary.

Does the RadGrid have functionality for using reflection to display the full details of the object I'm trying to bind to it? Is there some way around having to create GridRelationFields? Or will I have to make wrapper objects and programmatically generate and assign ID fields to get this to work?

Bind to object without IDs

The object structure I'm trying to bind to TreeList has nested Lists as properties, but no ID fields. Can I bind to the TreeList control in such a way that its structure matches the structure of my object without the need for setting the key properties?

How to Show/hide filter items based on user rights.

Folks, Using RadControls for ASP.NET AJAX Q1 2013 with VS 2010. I would like to conditionally hide certain filter items based on user rights. Example I have a session variable i.e. Session["UserRights"].

If Session["UserRights"] == "Supervisor" then show all available filter items in a GridDateTimeColumn, if not then available filter items in that column will be No Filter & Equal To.

Attached is my screen shot. Any help will be appreciated.

Thanks
