Setting the Control in RadGrid to Visible-False - html

Question

I need help with getting the ID of the Control in RadGrid in order to set it Visable=False.
The last function is actually creating a pic based on the value that's coming from the DB. How can I set the HyperLink next to the Pic that I'm adding to Visible false?
I think that I need to send that function RenderLinked the hyperlink control but I don't know how and I hope that some one can show me the way.

If you want to set some control's attribute visible=false in code behind when rows are bound to data 1 by 1 you may use RowDataBound event and write following code in it's handler
Control_Type Control_ID = (Control_Type) e.Row.FindControl("Control_ID");
Control_ID.Visible = false;
And if you want to set it in javascript,
rgPhoneBook.Rows[Record_Index].Cells[0].Visible = false;
Hope this helps you. The above code is in C#, please convert it to it's equivalent in VB.
