Datatable绑定GridView[转]

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

1 dg.DataSource  =  ds;
2 dg.DataBind();

 

Code
 1    <asp:GridView ID="dg" runat="server" AutoGenerateColumns="False" BorderWidth="0px">
 2        <Columns>
 3            <asp:BoundField HeaderText="id" DataField="id" ReadOnly="True" ShowHeader="False">
 4            asp:BoundField>
 5            <asp:BoundField HeaderText="名字" DataField="name" HtmlEncode="False">asp:BoundField>
 6            <asp:TemplateField HeaderText="图片">
 7                <EditItemTemplate>
 8                    <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("img") %>'>asp:TextBox>
 9                EditItemTemplate>
10                <ItemTemplate>
11                    <asp:Label ID="Label1" runat="server" Text='<%# Bind("img") %>'>asp:Label>
12                ItemTemplate>
13            asp:TemplateField>
14            <asp:ImageField HeaderText="图片" DataImageUrlField="img">
15                <ControlStyle Width="100px" Height="100px" />
16            asp:ImageField>
17            <asp:BoundField HeaderText="时间" DataField="timer" DataFormatString="{0:d}">asp:BoundField>
18        Columns>
19    asp:GridView>
