基本步骤：
1.先创建一个名为“ds”的Datset
2.再创建一个名为“dt”的Datatable
3.为dt创建Column
4.创建一个名为“dr”的DataRow，使用dr.add（）添加，dt.newrow添加新行。
5.向ds中添加dt
6.Datatable数据绑定控件GridView
dg.DataSource = ds;
dg.DataBind();
<asp:GridView ID="dg" runat="server" AutoGenerateColumns="False" BorderWidth="0px" >
<Columns>
<asp:BoundField HeaderText="id" DataField="id" ReadOnly="True" ShowHeader="False" ></asp:BoundField >
<asp:BoundField HeaderText="名字" DataField="name" HtmlEncode="False"></asp:BoundField >
<asp:TemplateField HeaderText="图片">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("img") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("img") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:ImageField HeaderText="图片" DataImageUrlField="img"><ControlStyle Width="100px" Height="100px" /></asp:ImageField>
<asp:BoundField HeaderText="时间" DataField="timer" DataFormatString="{0:d}"></asp:BoundField >
</Columns>
</asp:GridView> |
