Answer 1

不够再给分，CSDN高手如云，我听别人说的，怎没有帮我呢，是不是不屑一顾呢？，哈哈。开个玩笑。

Answer 2

部分代码：aspx: <div>
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
            <Columns>
                <asp:BoundField DataField="OrderID" HeaderText="OrderID" />
                <asp:BoundField DataField="Name" HeaderText="Name" />
                <asp:BoundField DataField="Department" HeaderText="Department" />
                 <asp:TemplateField HeaderText="Action">
                   <ItemTemplate >
                       <asp:LinkButton ID="btnSelect" runat="server" Text="Select" OnClick="btnSelect_Click"></asp:LinkButton>
                      <asp:LinkButton ID="btnDel" runat="server" Text="Delete" OnClick="btnDel_Click" CommandArgument='<%# DataBinder.Eval(Container.DataItem,"OrderID") %>'  OnClientClick="javascript:return window.Confirm('Are you sure to delete this record ?')"></asp:LinkButton>
                   </ItemTemplate>
                 </asp:TemplateField>
            </Columns>
        </asp:GridView>
        <br />
        <ul>
            OrderID: &nbsp; &nbsp;
            <asp:TextBox ID="txtOrder" runat="server"></asp:TextBox>
         </ul>
         <ul>
            Name: &nbsp; &nbsp; &nbsp; &nbsp;
             <asp:TextBox ID="txtName" runat="server"></asp:TextBox>
        </ul>
          <ul>
            Department:<asp:TextBox ID="txtDepart" runat="server"></asp:TextBox>
        </ul>
     </div>
cs:  private DataSet DataSource
    {
        get
        {
            DataRow dr=null;
            DataSet ds = new DataSet();
            DataTable dt = new DataTable();
            dt.Columns.Add(new DataColumn("OrderID", typeof(int)));
            dt.Columns.Add(new DataColumn("Name", typeof(string)));
            dt.Columns.Add(new DataColumn("Department", typeof(string)));
            dr = dt.NewRow();
            dr["OrderID"] = 1;
            dr["Name"] = "James";
            dr["Department"] = "ProjectM";
            dt.Rows.Add(dr);            dr["OrderID"] = 2;
            dr["Name"] = "Lucy";
            dr["Department"] = "IT";
            dt.Rows.Add(dr);
            ds.Tables.Add(dt);
            return ds;
        }
    }    protected void btnSelect_Click(object sender, EventArgs e)
    {
        //这里我是用的临时数据，你可以根据自己的数据源进行操作.
        string id = ((LinkButton)sender).CommandArgument;
        DataTable dt = DataSource.Tables[0];
        dt.PrimaryKey = new DataColumn[] { dt.Columns["OrderID"] };
        DataRow row = dt.Rows.Find(id);
        if (row != null)
        {
            txtOrder.Text = row["OrderID"].ToString();
            txtName.Text=row["Name"].ToString();
            txtDepart.Text = row["Department"].ToString();        }
    }    protected void btnDel_Click(object sender, EventArgs e)
    {
        string id = ((LinkButton)sender).CommandArgument;
        //拿到id后，自己构造Sql删除，并重新绑定GridView
    }

Answer 3

绑定GridView的过程我略过了.
 在page_load里绑下就可以了.

Answer 4

经测试有些小问题:更正如下:
 aspx:
  <div>
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
            <Columns>
                <asp:BoundField DataField="OrderID" HeaderText="OrderID" />
                <asp:BoundField DataField="Name" HeaderText="Name" />
                <asp:BoundField DataField="Department" HeaderText="Department" />
                 <asp:TemplateField HeaderText="Action">
                   <ItemTemplate >
                       <asp:LinkButton ID="btnSelect" runat="server" CommandArgument='<%# DataBinder.Eval(Container.DataItem,"OrderID") %>'  Text="Select" OnClick="btnSelect_Click"></asp:LinkButton>
                      <asp:LinkButton ID="btnDel" runat="server" Text="Delete" OnClick="btnDel_Click" CommandArgument='<%# DataBinder.Eval(Container.DataItem,"OrderID") %>'  OnClientClick="javascript:return window.confirm('Are you sure to delete this record ?')" ></asp:LinkButton>
                   </ItemTemplate>
                 </asp:TemplateField>
            </Columns>
        </asp:GridView>
        <br />
        <ul>
            OrderID: &nbsp; &nbsp;
            <asp:TextBox ID="txtOrder" runat="server"></asp:TextBox>
         </ul>
         <ul>
            Name: &nbsp; &nbsp; &nbsp; &nbsp;
             <asp:TextBox ID="txtName" runat="server"></asp:TextBox>
        </ul>
          <ul>
            Department:<asp:TextBox ID="txtDepart" runat="server"></asp:TextBox>
        </ul>
     </div>
 cs:  protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            GridView1.DataSource = DataSource;
            GridView1.DataBind();
        }
    }    private DataSet DataSource

            DataSet ds = new DataSet();

            dr["OrderID"] = 2;
            dr["Name"] = "Lucy";
            dr["Department"] = "IT";
            dt.Rows.Add(dr);
            ds.Tables.Add(dt);
            return ds;
        }
    }    protected void btnSelect_Click(object sender, EventArgs e)
    {
        //这里我是用的临时数据，你可以根据自己的数据源进行操作.
        string id = ((LinkButton)sender).CommandArgument;
