How to hide a column (GridView) but still access its value?

Question

I have a GridView with a DataSource (SQL Database). I want to hide a column, but still be able to access the value when I select the record. Can someone show me

Answer 1

If you do have a TemplateField inside the columns of your GridView and you have, say, a control named blah bound to it. Then place the outlook_id as a HiddenField there like this:

    
        Existing Control
        
    

Now, grab the row in the event you want the outlook_id and then access the control.
For RowDataBound access it like:

string outlookid = ((HiddenField)e.Row.FindControl("HiddenOutlookID")).Value;

Do get back, if you have trouble accessing the clicked row. And don't forget to mention the event at which you would like to access that.
