I'm trying to filter a gridview in asp with sqldatasource filterexpression and parameters. I can't find what I'm missing. When I change the drop downs nothing happens. Any help would be greatly appreciated as I'm new to ASP.

Here is the dropdownlist:

XML

<asp:DropDownList ID="dl_filter_Inst" runat="server" DataSourceID="ds_Inst"
                DataTextField="Num" DataValueField="Num" width="98%"
                AppendDataBoundItems="true">
                <asp:ListItem Selected="True" Value="">Show All</asp:ListItem>
                </asp:DropDownList>

Here is the datasource and filterparameters:

XML

<asp:SqlDataSource ID="ds_Inst" runat="server"
    ConnectionString="<%$ ConnectionStrings:SAPConfiguration.My.MySettings.SqlConn %>"
    SelectCommand="getInst" InsertCommand="insertInst"
        InsertCommandType="StoredProcedure" SelectCommandType="StoredProcedure"
        UpdateCommand="updateInst" UpdateCommandType="StoredProcedure"
        OldValuesParameterFormatString="original_{0}" EnableCaching="True"
        CacheDuration="600" FilterExpression="Num like '{0}'">
        <FilterParameters>
            <asp:ControlParameter ControlID="dl_filter_Inst" Name="Num"
                PropertyName="SelectedValue" DefaultValue="&quot;&quot;" />
            <asp:ControlParameter ControlID="tb_filter_Name" Name="Name"
                PropertyName="Text" />
            <asp:ControlParameter ControlID="rb_Enabled" Name="Enabled"
                PropertyName="Checked" />
            <asp:ControlParameter ControlID="rb_branchBilling" Name="BranchBilling"
                PropertyName="Checked" />
            <asp:ControlParameter ControlID="dl_filter_DB" Name="DB"
                PropertyName="SelectedValue" />
            <asp:ControlParameter ControlID="dl_MF" Name="MF"
                PropertyName="SelectedValue" />
            <asp:ControlParameter ControlID="dl_center" Name="Center"
                PropertyName="SelectedValue" />
        </FilterParameters>

Here is the gridview and column to be filtered:

XML

<asp:GridView ID="gv_Inst" runat="server" AutoGenerateColumns="False"
   DataSourceID="ds_Inst" AllowPaging="True" AllowSorting="True"
       AutoGenerateEditButton="True"
       PageSize="25" CssClass="gridview">
       <AlternatingRowStyle cssclass="altrow" />
   <Columns>
       <asp:BoundField DataField="Idx" HeaderText="Idx" SortExpression="Idx"
           InsertVisible="False" visible="false" >
       </asp:BoundField>
       <asp:BoundField DataField="Num" HeaderText="Number" SortExpression="Num"
           ReadOnly="False">
       <ControlStyle CssClass="controlClass" />
       </asp:BoundField>

The DropDownList does not automatically post back when the selection changes.

Add AutoPostBack="True"

XML

<asp:DropDownList ID="dl_filter_Inst" runat="server" DataSourceID="ds_Inst"
                AutoPostBack="True" 
                DataTextField="Num" DataValueField="Num" width="98%"
                AppendDataBoundItems="true">
                <asp:ListItem Selected="True" Value="">Show All</asp:ListItem>
                </asp:DropDownList>

Ended up addiing variable to SPROC and using this code:

VB

Protected Sub btn_Apply_Click(sender As Object, e As EventArgs) Handles btn_Apply.Click
        gv_Inst.DataBind()
        btn_Clear.Enabled = True
    End Sub

    Protected Sub ds_Inst_Selecting(sender As Object, e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs) Handles ds_Inst.Selecting
        '<SelectParameters>
        '    <asp:Parameter Name="num" Type="String" />0
        '    <asp:Parameter Name="name" Type="String" />1
        '    <asp:Parameter Name="dbname" Type="String" />2
        '    <asp:Parameter Name="enable" Type="Boolean" />3
        '    <asp:Parameter Name="disable" Type="Boolean" />4
        '    <asp:Parameter Name="enableBranchBilling" Type="Boolean" />5
        '    <asp:Parameter Name="disableBranchBilling" Type="Boolean" />6
        '    <asp:Parameter Name="mainframe" Type="String" />7
        '    <asp:Parameter Name="center" Type="String" />8
        '  </SelectParameters>

        If cb_Inst.Checked Then
            e.Command.Parameters(0).Value = dl_filter_Inst.SelectedValue
        Else
            e.Command.Parameters(0).Value = "%"
        End If

        If cb_Name.Checked Then
            e.Command.Parameters(1).Value = tb_filter_Name.Text
        Else
            e.Command.Parameters(1).Value = "%"
        End If

        If cb_DB.Checked Then
            e.Command.Parameters(2).Value = dl_filter_DB.SelectedValue
        Else
            e.Command.Parameters(2).Value = "%"
        End If

        If cb_filter_Enable.Checked Then
            If rb_Enabled.Checked Then
                e.Command.Parameters(3).Value = True
                e.Command.Parameters(4).Value = True
            Else
                e.Command.Parameters(3).Value = False
                e.Command.Parameters(4).Value = False
            End If
        Else
            e.Command.Parameters(3).Value = True
            e.Command.Parameters(4).Value = False
        End If

        If cb_filter_BranchBilling.Checked Then
            If rb_branchBilling.Checked Then
                e.Command.Parameters(5).Value = True
                e.Command.Parameters(6).Value = True
            Else
                e.Command.Parameters(5).Value = False
                e.Command.Parameters(6).Value = False
            End If
        Else
            e.Command.Parameters(5).Value = True
            e.Command.Parameters(6).Value = False
        End If

        If cb_MF.Checked Then
            e.Command.Parameters(7).Value = dl_MF.SelectedValue
        Else
            e.Command.Parameters(7).Value = "%"
        End If

        If cb_Center.Checked Then
            e.Command.Parameters(8).Value = dl_center.SelectedValue
        Else
