        <HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="#FFFFCC" />

推荐答案

首先检查天气方法是否填充数据表。在我的例子中，在代码的第2行声明一个调试点。如果您的DataTable为空，则不会显示gridview。

First check weather the method is filling data table or not. Declare a debug point on line 2 of code in my case. If your DataTable is empty than it will not show you gridview.

DataTable dataTable = new DataTable();
dataTable = gettingDataFromSomeMethod();

GridView1.DataSource = dataTable;
GridView1.DataBind();

你可以做的另一件事是将showHeader属性赋予gridview，所以至少你的标题会尽管你的数据表是否是空的，但仍然可见。

One more thing you can do is give ShowHeader attribute to gridview so atleast your header will be visible inspite of, whether your datatable is empty of filled.

<asp:gridview id="GridView1" runat="server" showheader="true" xmlns:asp="#unknown" />
