Question

帮助！

我有一个带有<asp:TemplateField><ItemTemplate>组合的GridView。在这个组合里面，我有一个<asp:ImageButton ...>它看起来不错，但每次点击这个按钮我都会收到一个错误：

Microsoft JScript运行时错误： Sys.WebForms.PageRequestManagerServerErrorException：未知错误在服务器上处理请求时发生。状态代码从服务器返回的是：500

我甚至没有看到按钮触发的事件。

这是我的HTML代码：

<asp:GridView 
    ID="PuckGridView" 
    runat="server" 
    EmptyDataText="Sorry, no data available"
    AutoGenerateColumns="False" 
    AllowSorting="True" 
    Font-Size = "X-Small" 
    Width = "1150px"
    Height = "410px"
    onselectedindexchanged="PuckGridView_SelectedIndexChanged" 
    onrowcommand="RowUserActivity" 
    onpageindexchanging="PuckGridView_PageIndexChanging" 
    onrowdatabound="PuckGridView_RowDataBound" 
    GridLines="Horizontal"
    onsorting="PuckGridView_Sorting"
    HeaderStyle-HorizontalAlign="Left">
    <AlternatingRowStyle BackColor="#99CCFF" ForeColor="Black" />
        <Columns>
        <asp:TemplateField SortExpression="Status" HeaderText="Status">
             <ItemTemplate>
                <asp:ImageButton runat="server" ImageUrl='<%# "~/Images/" +  Eval("StatusImage").ToString() %>' CommandName="UpdateStatus" />
                <%-- <asp:Image ID="statusImage" runat="server" ImageUrl='<%# "~/Images/" +  Eval("StatusImage").ToString() %>' />--%>
                <asp:Label ID="status" runat="server" Text='<%# Bind("StatusText") %>'></asp:Label>
                <br />
                <asp:Image ID="onCallImage" runat="server" ImageUrl='<%# "~/Images/" + DisplayCorrectOnCallImage(Eval("OnCallImage")) %>' />
                <asp:HiddenField ID="HiddenEmail" runat="server" Value='<%# Eval("Email") %>' />
                <asp:HiddenField ID="HiddenUserName" runat="server" Value='<%# Eval("UserName") %>' />
                <asp:HiddenField ID="HiddenFirstName" runat="server" Value='<%# Eval("FirstName") %>' />
                <asp:HiddenField ID="HiddenLastName" runat="server" Value='<%# Eval("LastName") %>' />
            </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left" SortExpression="FirstName" DataField="FirstName" HeaderText="FirstName" Visible="true" />
        <asp:BoundField ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left" SortExpression="LastName" DataField="LastName" HeaderText="LastName" Visible="true" />
        <asp:BoundField ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left" DataField="OfficePhone" HeaderText="Phone" Visible="true" />
        <asp:BoundField ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left" SortExpression="TeamRole" DataField="TeamRole" HeaderText="Team/Role" Visible="true" />
        <asp:BoundField ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left" SortExpression="Location" DataField="Location" HeaderText="Location" Visible="true" />
        <asp:ButtonField  HeaderText="Mail" ButtonType="Image" CommandName="SendMail" ImageUrl="~/Images/mail.gif" Visible="true"/>
        <asp:TemplateField>
             <ItemTemplate>
                 <asp:Image ID="imgHours" ToolTip=' <%# Eval("Hours") %> ' ImageUrl='<%# "~/Images/clock.gif"  %>' runat="server" />
             </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField ItemStyle-HorizontalAlign="Left" DataField="Message" HeaderText="Message" Visible="true" />
    </Columns>
    <HeaderStyle BackColor="#CCCCCC" />
</asp:GridView>

Answer 1

尝试查看是否存在任何无效的html标记。或尝试viewstate = false

Answer 2

尝试删除此行：

 <%-- <asp:Image ID="statusImage" runat="server" ImageUrl='<%# "~/Images/" +  Eval("StatusImage").ToString() %>' />--%>

我之前在模板中评论了一些事情

同时检查您的

 onselectedindexchanged="PuckGridView_SelectedIndexChanged"

事件，因为当您点击行

时，这也可能会触发

每次我点击<asp：imagebutton> </asp：imagebutton>时出现“Microsoft JScript运行时错误：Sys.WebForms.PageRequestManagerServerErrorException：”错误
