ASP.NET 2.0提供了功能强大的数据绑定控件GridView、在使用中，一些属性和方法经常会与ASP.NET 1.1中的DataGrid混淆(VS2005中依然可以使用DataGrid，手动添加到工具箱或HTML状态输入代码)，下面我们分别用GridView和DataGrid实现其数据绑定、编辑、更新、删除等，从其代码中看两者的不同。
页面：
1 <asp:GridView ID="GridView1" runat="server" Width="100%" OnRowEditing="GridView1_RowEditing" OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowUpdating="GridView1_RowUpdating" DataKeyNames="cat_id" OnRowDeleting="GridView1_RowDeleting">
2 <Columns>
3 <asp:BoundField DataField="cat_tag" HeaderText="分类名称" />
4 <asp:BoundField DataField="rec_dd" HeaderText="创建日期" />
5 <asp:CommandField ShowEditButton="True" />
6 <asp:CommandField ShowDeleteButton="True" />
7 </Columns>
8 </asp:GridView>
1 <asp:DataGrid ID="DataGrid1" runat ="server" Width="100%" OnCancelCommand="DataGrid1_CancelCommand" OnEditCommand="DataGrid1_EditCommand" OnUpdateCommand="DataGrid1_UpdateCommand" DataKeyField="cat_id" OnDeleteCommand="DataGrid1_DeleteCommand" >
2 <Columns>
3 <asp:BoundColumn DataField="cat_tag" HeaderText="分类名称"></asp:BoundColumn>
4 <asp:BoundColumn DataField="rec_dd" HeaderText="创建日期" ></asp:BoundColumn>
5 <asp:EditCommandColumn CancelText="取消" EditText="编辑" UpdateText="更新"></asp:EditCommandColumn>
6 <asp:ButtonColumn CommandName="Delete" Text="删除"></asp:ButtonColumn>
7 </Columns>
8 </asp:DataGrid>
代码实现：
1 // 数据绑定
2 private void GridBind()
3 {
4 .
5 GridView1.DataSource = dt;
6 GridView1.DataBind();
7 DataGrid1.DataSource = dt;
8 DataGrid1.DataBind();
9 }
1、GridView
1 // 编辑
2 protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
3 {
4 GridView1.EditIndex = e.NewEditIndex;
5 GridBind();
6 }
7 //取消
8 protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
9 {
10 GridView1 .EditIndex = -1;
11 GridBind();
12 }
13 //更新
14 protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
15 {
16 string id = GridView1.DataKeys[e.RowIndex][0].ToString();
17 string newtxt = ((TextBox)GridView1.Rows[e.RowIndex].Cells[0].Controls[0]).Text;
18 string strSql = "UPDATE cat SET cat_tag='" + newtxt + "' WHERE cat_id=" + id;
19 uc.ExecuteQuery(strSql);
20 GridView1.EditIndex = -1;
21 GridBind();
22 }
23 //删除
24 protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
25 {
26 string id = GridView1.DataKeys[e.RowIndex][0].ToString();
27 string strSql = "DELETE FROM cat WHERE cat_id=" + id;
28 uc.ExecuteQuery(strSql);
29 GridView1.EditIndex = -1;
30 GridBind();
31 }
2、DataGrid
1 // 编辑
2 protected void DataGrid1_EditCommand(object source, DataGridCommandEventArgs e)
3 {
4 DataGrid1.EditItemIndex = e.Item.ItemIndex;
5 GridBind();
6 }
7 //取消
8 protected void DataGrid1_CancelCommand(object source, DataGridCommandEventArgs e)
9 {
10 DataGrid1.EditItemIndex = -1;
11 GridBind();
12 }
13 //更新
14 protected void DataGrid1_UpdateCommand(object source, DataGridCommandEventArgs e)
15 {
16 string id = DataGrid1.DataKeys[e.Item.ItemIndex].ToString();
17 string newtxt = ((TextBox)e.Item.Cells[0].Controls[0]).Text;
18 string strSql = "UPDATE cat SET cat_tag='" + newtxt + "' WHERE cat_id=" + id;
19 uc.ExecuteQuery(strSql);
20 DataGrid1.EditItemIndex = -1;
21 GridBind();
22 }
23 //删除
24 protected void DataGrid1_DeleteCommand(object source, DataGridCommandEventArgs e)
25 {
26 string id = DataGrid1 .DataKeys[e.Item .ItemIndex].ToString();
27 string strSql = "DELETE FROM cat WHERE cat_id=" + id;
28 uc.ExecuteQuery(strSql);
29 DataGrid1.EditItemIndex = -1;
30 GridBind();
31 }
