I have a grid that contains several columns. One column of the grid has data but is also a link to another .aspx page. Using the DataFormat property in the column "op" of the grid, I have the following: <a href='FlowExceptionsDetail.aspx?id={0}'>{0}</a>

I have decided that I need to pass another parameter in the statement along w/ the op, HOWEVER, the additional parameter is NOT part of the grid itself, rather it is a datepicker field above the grid.
I want to pass the date that is selecteddate of the datepicker. The whole screen is nothing more than a datepicker and a grid. Would I use something like:

<a href='FlowExceptionsDetail.aspx?id={0}&id2={1}'>{0}</a>

If so, how do I designate the "id2={1}" means to pass the "this.dpEffDate.SelectedDate" value???
