下面是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">

<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>
I am not using any serverside code. 我没有使用任何服务器端代码。 Whenever I use to run it the parent page becomes entire white.
每当我用它来运行它时,父页面就变成了整个白色。 Why????
为什么????
Update 更新
Final result i am getting, I have lots of user controls and databinding there. 我得到的最终结果,我有很多用户控件和数据绑定。 No thing rendering.
没有渲染的东西。 Seems entire page viewstate is going false.
似乎整个页面viewstate都是假的。

Please help me 请帮我
Try to put at least Response.Write("Test");
尝试至少放置
Response.Write("Test");
in the Page_Load on the server side code, do you see this in the browser? 在服务器端代码的Page_Load中,您是否在浏览器中看到了这一点?
could it be that you are returning no records from the database? 可能是你没有从数据库中返回任何记录?
("I am not using any serverside code" that's not true, but nvm.) (“我没有使用任何服务器端代码”,这不是真的,但是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: 尝试在一个简单的标签或其他东西中使用它,并在它工作后添加图像和超链接,不要尝试做复杂的东西,一步一步做:
Text=' <%#Eval("Name") %>'
or 要么
Text='<%# DataBinder.Eval(Container.DataItem, "Name")%>'
Also, binding the datasource would be easier to do/test in code-behind. 此外,绑定数据源将更容易在代码隐藏中进行/测试。
