Hi Guys,

I have a Gridview Custom Control (class library project). What I want to do is, add a button to the page. Once the button is clicked, I need a ModalPopupEctender to come up with a checkboxlist of all the Columns in the SQLDataSource that populates the Gridview.

Now since this is a class library project that inherits from the Gridview, I'm not sure how I can add a div at the very top of the page, with the "Choose Columns" button.

Should I create a user control that contains my Custom Gridview? Reason I want to do what I ask is because I want to reuse this in as many projects as I can, I wan this functionality built in to my dll. please help
