I've created a gridview bound it to a dataset and added two checkbox columns. What I would like to have happen is when a user checks the box, then clicks the submit button, the row with the box checked will be updated in the database. The problem I'm facing is when the user clicks on a checkbox and pushes the submit button the checkbox.checked method is always False.

Protected Sub btnSubmit_Clicked(ByVal sender As Object, ByVal e As EventArgs) Handles btnSubmit.Clicked

     For Each row As GridViewRow in grdResults.Rows
          Dim chkbox1 As CheckBox = CType(row.FindControl("ckb1"), CheckBox)
          If chkbox1.Checked = True

               check1 = True
               EdIDs += CType(row.FindControl("edid1"), Label).Text.ToString() + ","
          End If
          Dim chkbox2 As CheckBox = CType(row.FindControl("ckb2"), CheckBox)
          If chkbox2 .Checked = True

               check2 = True
               EdIDs += CType(row.FindControl("edid2"), Label).Text.ToString() + ","
          End If
