Hide columns when AutoGenerateColumns is True
posted

Is there a way to hide columns in server side using AutoGenerateColumns as True?

If I use a BoundDataField for the columns I want to hide and those columns are shown twice and when I set the property Hide to True I got the following error:

'The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>). '

Even when I hide a column with js I got the same error.

What can I do?

    Hello,

    if you are using BoundDataField for the columns, you should set AutoGenerateColumns to false. That's why your columns are shown twice.
    I believe you are getting the error because you're using <%=  %>. Try using  <%#  %>.
