很简单啊。
我现在做的项目的一个实例给你吧。
1.Gridview
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" DataKeyNames="PlantDBID"
OnRowDeleting="GridView1_RowDeleting" HeaderStyle-BackColor="Green"
onrowdatabound="GridView1_RowDataBound">
<Columns>
<asp:BoundField HeaderText="数据库ID" DataField="PlantDBID" />
<asp:BoundField HeaderText="数据库标题" DataField="PlantDBName" />
<asp:BoundField HeaderText="图片" DataField="Image" />
<asp:BoundField HeaderText="介绍" DataField="Introduction" />
<asp:TemplateField>
<HeaderTemplate>
操作</HeaderTemplate>
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Delete"
Text="删除" OnClientClick='<%# "if (!confirm(\"你确定要删除" + Eval("PlantDBName").ToString() + "吗?\")) return false;"%>'></asp:LinkButton>
<a id="A1" href='<%#"DisplantPlantDB.aspx?id="+Eval("PlantDBID") %>' runat="server">修改</a>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<FooterStyle BackColor="#FFFFCC" ForeColor="#330099" />
<PagerStyle BackColor="#FFFFCC" ForeColor="#330099" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="#663399" />
<HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="#FFFFCC" />
</asp:GridView>
这里的重点是： <a id="A1" href='<%#"DisplantPlantDB.aspx?id="+Eval("PlantDBID") %>' runat="server">修改</a>
这句话的意思说，把当前的行的ID 传递到DisplantPlantDB.aspx这个页面中。
2.在DisplantPlantDB.aspx这个页面中
放进table
<table>
<tr>
<td>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</td>
<td>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
</td>
<td>
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
</td>
</tr>
</table>
3..在DisplantPlantDB.aspx这个页面中 绑定数据
3.1 string id = Request["id"]; 获取那边传过来的ID
3.2if (id != null)
{
BindData(id);
}
3.3 绑定事件
protected void BindData(string id)
{
PlantDBBLL plantBLL = new PlantDBBLL();//三层架构的一个业务处理层
PlantDB plant = plantBLL.GetPlantDBByID(id);//获取数据
TextBox1.Text = plant.PlantDBName;//开始绑定
TextBox2.Text = plant.Introduction;
}
很简单吧。有问题在讨论，节日快乐。

风逝19900311 正解，思路：点击GridView触发事件，可以是PageIndexChanging，updateing，selecting等都可以，关键是GridViewPageEventArgs e可以获得你选择的那行，还可以用GridView.rows[e.index].cells[i]或得改行每列的数据

<asp:GridView ID="gv" runat="server"
CellPadding="3"
GridLines="Horizontal" BackColor="White" BorderColor="#E7E7FF"
BorderStyle="None" BorderWidth="1px" Height="150px" Width="329px"
AllowPaging="True" onpageindexchanging="gv_PageIndexChanging" PageSize="6" >
protected void gv_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
string connString = "uid=sa;pwd=1;database=shuju;server=.";
SqlConnection conn = new SqlConnection(connString);
DataTable dt = new DataTable();
string s = "select * from jieshao";
da = new SqlDataAdapter(s, conn);
da.Fill(dt);
this.gv.PageIndex = e.NewPageIndex;
gv.DataSource = dt;
gv.DataBind();
}
gv是grid view的简写，希望你能看懂，能帮到你。
