    I have to create a grid where one of the columns will be a template column which will hold a Drop down and +/X button. On Clicking of + user can add as many dropdowns as they want and X will delete them in a single row and this data will be saved back to DB.

    I know i will have create a grid in Page_init and use ITemplate to create this. every row will be uniquely identified by a value and i need to access that value inside the ITemplate to store the data back to DB to keep track of how many dropdowns have been added so that on page refresh i can load them back in. Is it possible? I tried but i cannot access the data inside the ITemplate->InstantiateIn method since data bound has not happened yet. 

    Any example?

    Hi,

    The required functionality is a custom scenario that is not supported out of the box for the RadGrid controls. I would suggest you to revise the online topics below that can help in implementing this functionality on your side:
    http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/defining-structure/creating-a-radgrid-programmatically#creating-template-columns-programmatically
    http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows

    You can access the controls form the template in the PreRender event.
