Dear All,

I want to filter a Database GridView from 4 different Dropdownlist Selection:

HTML Code:

<table id="tableColor" runat="server" style="margin: 10px;">
    <tr>
        <td nowrap="nowrap" bgcolor="#90ee90" style="background-color: #808080; color: #FFFFFF">
            Course name:
        </td>
        <td>
            <asp:DropDownList ID="ddlSearchCourseName" Width="230px" runat="server" AutoPostBack="true"
                DataSourceID="dropDownSearchCourseName" DataTextField="CourseName" DataValueField="CourseName"
                AppendDataBoundItems="true">
                <asp:ListItem Text="Select Course Name" Value="" />
            </asp:DropDownList>
            <asp:SqlDataSource ID="dropDownSearchCourseName" runat="server" ConnectionString="<%$ ConnectionStrings:DatabaseVestConnectionString1 %>"
                SelectCommand="SELECT DISTINCT CourseName FROM vts_Register"></asp:SqlDataSource>
        </td>
        <td nowrap="nowrap" bgcolor="#90ee90" style="background-color: #808080; color: #FFFFFF">
            Course year:
        </td>
        <td>
            <asp:DropDownList ID="ddlSearchCourseYear" Width="230px" runat="server" AutoPostBack="true"
                DataSourceID="dropDownSearchCourseYear" DataTextField="CourseReferanseNumber"
                DataValueField="CourseReferanseNumber" AppendDataBoundItems="true">
                <asp:ListItem Text="Select Year" Value="" />
            </asp:DropDownList>
            <asp:SqlDataSource ID="dropDownSearchCourseYear" runat="server" ConnectionString="<%$ ConnectionStrings:DatabaseVestConnectionString1 %>"
                SelectCommand="SELECT DISTINCT CourseReferanseNumber FROM vts_Register"></asp:SqlDataSource>
        </td>
        <td rowspan="2">
        </td>
    </tr>
    <tr>
        <td nowrap="nowrap" bgcolor="#90ee90" style="background-color: #808080; color: #FFFFFF">
            Course type:
        </td>
        <td>
            <asp:DropDownList ID="ddlSearchCourseType" Width="230px" runat="server" AutoPostBack="true"
                DataSourceID="dropDownSearchCourseType" DataTextField="CourseType" DataValueField="CourseType"
                AppendDataBoundItems="true">
                <asp:ListItem Text="Select Course Type" Value="" />
            </asp:DropDownList>
            <asp:SqlDataSource ID="dropDownSearchCourseType" runat="server" ConnectionString="<%$ ConnectionStrings:DatabaseVestConnectionString1 %>"
                SelectCommand="SELECT DISTINCT CourseType FROM vts_Register"></asp:SqlDataSource>
        </td>
        <td nowrap="nowrap" bgcolor="#90ee90" style="background-color: #808080; color: #FFFFFF">
            Course week:
        </td>
        <td>
            <asp:DropDownList ID="ddlSearchCourseWeek" Width="230px" runat="server" AutoPostBack="true"
                DataSourceID="dropDownSearchCourseWeek" DataTextField="CourseUkeNummer" DataValueField="CourseUkeNummer"
                AppendDataBoundItems="true">
                <asp:ListItem Text="Select Course Week" Value="" />
            </asp:DropDownList>
            <asp:SqlDataSource ID="dropDownSearchCourseWeek" runat="server" ConnectionString="<%$ ConnectionStrings:DatabaseVestConnectionString1 %>"
                SelectCommand="SELECT DISTINCT CourseUkeNummer FROM vts_Register"></asp:SqlDataSource>
        </td>
    </tr>
</table>

DataSource:

<asp:SqlDataSource ID="vts_RegisterDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:DatabaseVestConnectionString1 %>"
    DeleteCommand="DELETE FROM [vts_Register] WHERE [CourseID] = @CourseID" InsertCommand="INSERT INTO [vts_Register] ([CourseStatus], [CourseArrangeur], [CourseName], [CourseType], [CourseFagOmrade], [CourseLokalAdresse], [CourseReferanseNumber], [CourseStartDato], [CourseSluttDato], [CourseTotalDager], [CourseUkeNummer], [CourseTotalPlasse], [CourseAntallLedigPlasse], [CoursePameldingFraDato], [CourseDescription], [AdminDocumentName], [AdminOfficerOfCaseName], [AdminOfficerOfCaseEmail], [CourseRegistreringDato]) VALUES (@CourseStatus, @CourseArrangeur, @CourseName, @CourseType, @CourseFagOmrade, @CourseLokalAdresse, @CourseReferanseNumber, @CourseStartDato, @CourseSluttDato, @CourseTotalDager, @CourseUkeNummer, @CourseTotalPlasse, @CourseAntallLedigPlasse, @CoursePameldingFraDato, @CourseDescription, @AdminDocumentName, @AdminOfficerOfCaseName, @AdminOfficerOfCaseEmail, @CourseRegistreringDato)"

    SelectCommand="SELECT * FROM [vts_Register]" FilterExpression="CourseStatus = '{0}' AND CourseName LIKE '%{1}%'">
    <FilterParameters>
        <asp:ControlParameter Name="CourseStatus" ControlID="ddlCourseStatus" PropertyName="SelectedValue"
            Type="String" />
        <asp:ControlParameter Name="CourseName" ControlID="ddlSearchCourseName" PropertyName="SelectedValue"
            Type="String" />
    </FilterParameters>
</asp:SqlDataSource>
