    Grouping giving problem

    Hi,

    I want to do grouping in my Grid and at the same time have the GridPanel editable so that the user can edit the values.
    But i am specifying my grid for grouping then i am getting this strange error
    Though after this error in my code behind when i still press F5 i can see the form with grouping.

    Here is the whole error. Can you please tell me what could be the problem?

    System.InvalidOperationException occurred
      Message=Can't find the property 'Reader' in class 'AxTextBox'
      Source=Ext.Net
