Question

How do I pass the Control ID in a gridview that is derived from a stored procedure into a variable. I will use the variable to pass into the database later on to return some results. Thanks.

Answer 1

var controlId = ((LinkButton)gridView1.Rows[0].FindControl("lbName")).Id;

Are you trying to do something like the above?

Update
You can use the OnSelectedIndex event of the GridView to find the row that was select.

  void GridView_SelectedIndexChanged(Object sender, EventArgs e)
  {
    // Get the currently selected row using the SelectedRow property.
    GridViewRow row = CustomersGridView.SelectedRow;

    var controlId = ((LinkButton)row.FindControl("lbName")).Id;
  }
