在gridview中的c＃可点击的行

Question

我对这个感谢非常好的教程。但问题是页面重新加载，所以点击工作，但其余的代码没有通过...任何想法，为什么？

protected void OnRowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e) 
    { 
     if (e.Row.RowType == DataControlRowType.DataRow) 
     { 
      e.Row.Attributes["onclick"] = Page.ClientScript.GetPostBackClientHyperlink(GridView1, "Select$" + e.Row.RowIndex); 
      e.Row.ToolTip = "Click to select this row."; 
     } 
    } 
    protected void OnSelectedIndexChanged(object sender, EventArgs e) 
    { 

      int index = GridView1.SelectedRow.RowIndex; 
      string Firstname = GridView1.SelectedRow.Cells[0].Text; 
      string Surname = GridView1.SelectedRow.Cells[1].Text; 
      string ID = GridView1.SelectedRow.Cells[2].Text; 
      string Occupation = GridView1.SelectedRow.Cells[3].Text; 
      string Place = GridView1.SelectedRow.Cells[4].Text; 
      string Phone = GridView1.SelectedRow.Cells[5].Text; 
      string Cellular = GridView1.SelectedRow.Cells[6].Text; 
      string Mail = GridView1.SelectedRow.Cells[7].Text; 
      Label1.Text = Firstname; 
      Label2.Text = Surname; 
      Label3.Text = ID; 
      Label4.Text = Occupation; 
      Label5.Text = Place; 
      Label6.Text = Phone; 
      Label7.Text = Cellular; 
      Label8.Text = Mail; 
      Panel1.Visible = true; 


    }

您必须注册event handler method，f.e.上aspx：

<asp:GridView ID="ContactsGridView" 
    DataSourceID="YourGridId" 
    OnSelectedIndexChanged="OnSelectedIndexChanged"   
    OnRowDataBound="OnRowDataBound" 
    runat="server"> 
    <SelectedRowStyle BackColor="Aqua" /> 
    </asp:GridView>
