我有一个gridview并启用了排序.运行应用程序时,我单击第一列进行排序.我得到这个错误:"GridView'gvOutlookMeldingen'触发了事件排序,但没有处理."

这是gridview:

<asp:GridView ID="gvOutlookMeldingen" runat="server" AllowSorting="True" AutoGenerateColumns="False" AutoGenerateSelectButton="True" onselectedindexchanged="GridView_SelectedIndexChanged">
    <Columns>
        <asp:TemplateField HeaderText="Melder" ItemStyle-HorizontalAlign="Center" SortExpression="Melder">
            <HeaderStyle BorderColor="#1A3491" Width="130px"></HeaderStyle>
            <ItemStyle Height="20px" HorizontalAlign="Center"></ItemStyle>
            <ItemTemplate>
                <%# (string)Eval("Melder") %>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField DataField="Onderwerp" HeaderText="Onderwerp" />
        <asp:TemplateField HeaderText="Omschrijving">
            <ItemTemplate>
                <div style="overflow:auto; width: 500px; height: 200px;">
                    <asp:Label ID="lblOmschrijving" runat="server" Text='<%# Bind("Omschrijving")%>'></asp:Label>
                </div>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField DataField="Meldingsdatum" HeaderText="Meldingsdatum" />
        <asp:BoundField DataField="OutlookID" HeaderText="OutlookID" />
    </Columns>
</asp:GridView>
