Hi Friends

I am having a grid control. In that grid control, having one of the column contains text box which is associated with calender extended control.

As per my requirement I would like to hide/show that column and to display the grid. But I am getting below error while doing the code

Error: Argument exception; values must not be null for controls and behaviours

Are you hiding column using the Visible property, if so then try hiding the columns using the css Display:none property.

Also if you have commented out code for any ajaxtoolkit controls in your page remove that also
