ASP.NET 2.0 SQL VB.NET Unbound Dropdownlist Gridview

Asked by: accessloans

I have a gridview that shows data from sql using a query. The query find the current month and year and displays cases for the current month. I have added two dropdownlists to my page. These are unbound. The first dropdownlist has the months in number format (01, 02, 03 etc). The second dropdownlist has the year which is worked with vb.net to add current year and three years previous (2007, 2006, 2005, 2004). I would like to be able to set the two dropdownlists to a month and year and have the gridview automatically change and show the cases for that month and year.

I cant figure out how to tie the dropdownlists to the query for unbound dropdownlists.

The code i have just now is -

VB.NET

Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        lblmonth.Text = DateTime.Now.ToString("MMMM yyyy")

        If Not Page.IsPostBack Then
            Call Populate_MonthList()
            Call Populate_YearList()
        End If

    End Sub

    Sub Populate_MonthList()
        'Add each month to the list
        drpmonth.Items.Add("01")
        drpmonth.Items.Add("02")
        drpmonth.Items.Add("03")
        drpmonth.Items.Add("04")
        drpmonth.Items.Add("05")
        drpmonth.Items.Add("06")
        drpmonth.Items.Add("07")
        drpmonth.Items.Add("08")
        drpmonth.Items.Add("09")
        drpmonth.Items.Add("10")
        drpmonth.Items.Add("11")
        drpmonth.Items.Add("12")

        'Make the current month selected item in the list
        drpmonth.Items.FindByValue(DateTime.Now.Month).Selected = True

    End Sub

    Sub Populate_YearList()
        Dim intYear As Integer

        'Year list can be changed by changing the lower and upper
        'limits of the For statement    
        For intYear = DateTime.Now.Year - 3 To DateTime.Now.Year
            drpyear.Items.Add(intYear)
        Next

        'Make the current year selected item in the list
        drpyear.Items.FindByValue(DateTime.Now.Year).Selected = True
    End Sub

End Class

You should be able to accomplish this by using parameters in your SqlDataSource.

   <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:BC_BE_AccessConnectionString %>" SelectCommand="SELECT Lender.Company, COUNT(CaseProcessing.StatusID) AS Completed, SUM(vw_Case_CommissionTotal.CommissionIn) AS [Comm In], SUM(vw_Case_CommissionTotal.CommissionOut) AS [Comm Out], SUM(vw_Case_CommissionTotal.CommissionNet) AS [Comm Net] FROM CaseDetails INNER JOIN CaseProcessing ON CaseDetails.CaseID = CaseProcessing.CaseID INNER JOIN CaseUnderWriting ON CaseDetails.CaseID = CaseUnderWriting.CaseID INNER JOIN Lender ON CaseUnderWriting.LenderID = Lender.ID INNER JOIN vw_Case_CommissionTotal ON CaseProcessing.CaseID = vw_Case_CommissionTotal.caseid WHERE (MONTH(CaseProcessing.StatusDate) = @SelectMonth) AND (YEAR(CaseProcessing.StatusDate) = @SelectYear) AND (CaseDetails.LoanTypeID = 8) AND (CaseProcessing.StatusID = 22) GROUP BY Lender.Company ORDER BY Lender.Company">
      <SelectParameters>
         <asp:controlparameter name="SelectMonth" controlid="drpmonth" propertyname="SelectedValue"/>
         <asp:controlparameter name="SelectYear" controlid="drpyear" propertyname="SelectedValue"/>
