modalpopupextender with dynamic checkboxlist

[janetb99]

I have a checkboxlist populated by a datasource having a textbox as a controlparameter. The checkboxlist is located within a modalpopup. When I click the button, the checkboxlist shows the list pertaining to the previous select. If I close and click the button to show the modalpopup, the second click shows the updated checkboxlist. I've tried everything I can think of and nothing seems to work. The latest attempt is to have a dummy button (arcArcPat) for the modalpopup. I click on btnPrePat to get the dynamic checkbox, but no modalpopup appears. Of course, when I click on btnArcPat, everything's great because I've clicked on the btnPrePat first. I tried taking away the display:none; and then I only get a flash on the screen, nothing that stays. Help?

Protected Sub btnPrePat\_Click(sender As Object, e As EventArgs) Handles btnPrePat.Click 
    ds = New Data.DataSet 
    strSql = "SELECT TOP (100) PERCENT t.patID,  myType FROM blah, blah" 
    da = New Data.SqlClient.SqlDataAdapter(strSql, cn) 
    Try 
        da.Fill(ds, "patSearch1") 
        If ds.Tables("patSearch1").Rows.Count > 0 Then 
            cblPat.DataSource = ds.Tables("patSearch1") 
            cblPat.DataTextField = ds.Tables("pat").Columns("myType").ToString 
            cblPat.DataValueField = ds.Tables("pat").Columns("patID").ToString 
            cblPat.DataBind() 
        End If 
    Catch ex As Exception 
        Response.Write(ex.ToString) 
    End Try 
    mpePat.Show() 
End Sub

For anyone else, - just wanted you to know that I figured out the bigger problem. Something must have corrupted the ajaxcontroltoolkit installation just enough. Once I re-referenced it, everything started working fine. Sorry for the trouble and thanks for your help.
