I am using the Infragistics tools for developing the grid view.I need to hide the few columns dynamically.

I am doing like this


this.batchesGrid.Columns["CREATION_DATE"].Hidden = true;


Designer:

<ig:bounddatafield header-text="Creation Date" key="CREATION_DATE" width="190px" dataformatstring="{0:MM/dd/yyyy}"
="" datatype="System.DateTime" datafieldname="CREATION_DATE">


But still I am able to see the Creation Date header.
