    Hi,

     

    I am trying to have a radgrid working after having rows added or removed from it.

    The scenario is the following :

      I want to be able to add items that are selected in a grid (QuestionsGrid1) located in a bootstrap modal. Once applied, the code behind adds the new items

    to the main radgrid (QuestionsGrid) in a multipageview.

    The issue is that once a postback is done, the system is not able to find the control of the main grid (QuestionsGrid), and no matter what I do, i continuously get this error :

    "Uncaught TypeError: Cannot set property 'control' of undefined"

    Here is the ASPX code and the C# Code.

     

    Thanks for help.

     

    ASPX
