ASP.Net 和数据源的白页错误
我正在用户控件上使用 SqlDatasource 来使用数据列表。 html
<asp:DataList ID="dlFeaturedCatalogs" runat="server" RepeatColumns="2" Width="100%"
Font-Bold="False" Font-Italic="False" Font-Overline="False" Font-Strikeout="False"
Font-Underline="False" ShowFooter="False" CellPadding="4"
ForeColor="#333333" DataSourceID="FCDatasource"
DataKeyField="Id">
<FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<AlternatingItemStyle BackColor="White" ForeColor="#284775" />
<ItemStyle BackColor="#F7F6F3" ForeColor="#333333" />
<SelectedItemStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
<HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<ItemTemplate>
<table>
<tr>
<td style="padding-left: 5px; text-align: left; vertical-align: middle; font-size: 11px">
<asp:Image ID="imgList" runat="server" ImageAlign="AbsMiddle" ImageUrl="~/images/company.jpg" />
<asp:HyperLink ID="hlCategory" ForeColor="#005aa3" Font-Underline="false" runat="server"
NavigateUrl='<%# ResolveUrl(string.Format("~/BusinessBazaarAspx/CompDetls.aspx?cid={0}&name={1}",Common.EncodeTo64(Eval("Id").ToString()),Common.EncodeTo64(Eval("Name").ToString()) )) %>'
Text=' <%#Eval("Name") %>' Target="_blank"> </asp:HyperLink>
</td>
</tr>
</table>
</ItemTemplate>
</asp:DataList>
<asp:SqlDataSource ID="FCDatasource" runat="server"
ConnectionString="<%$ ConnectionStrings:BusinessBazaarConnectionString %>"
SelectCommand="SELECT [CompanyId], [CompanyName] FROM [tbl_Company] ORDER BY [CompanyName]">
</asp:SqlDataSource>
下面是我没有使用任何服务器端代码的 。每当我用来运行它时，父页面就会变成全白色。为什么？？？？
更新
我得到的最终结果，我有很多用户控件和数据绑定。没有渲染任何东西。似乎整个页面视图状态都变错误了。

</asp:SqlDataSource>
I am not using any serverside code. Whenever I use to run it the parent page becomes entire white. Why????
Update
Final result i am getting, I have lots of user controls and databinding there. No thing rendering. Seems entire page viewstate is going false.

尝试在服务器端代码的 Page_Load 中至少放置
Response.Write("Test");，您在浏览器中看到这个吗？可能是您没有从数据库返回任何记录吗？
Try to put at least
Response.Write("Test");in the Page_Load on the server side code, do you see this in the browser?could it be that you are returning no records from the database?
（“我没有使用任何服务器端代码”，这不是真的，而是 nvm。）
尝试在简单的标签或其他东西中使用它，在它工作后添加图像和超链接，不要尝试做复杂的事情，一步一步地做-step：
或者
此外，绑定数据源会更容易在代码隐藏中进行/测试。
("I am not using any serverside code" that's not true, but nvm.)
try using this in a simple label or something, and after it works add the images and hyperlinks, dont try to do complicated stuff, do it step-by-step:
or
Also, binding the datasource would be easier to do/test in code-behind.
