如何在沒有選擇按鈕的情況下選擇和取消選擇GridView中的行？

Question

我正在開發一個Master-Details GridView & DetailsView。一切正常，但我希望它刪除GridView中每行的選擇按鈕，並使用戶能夠通過單擊行中的任何位置或單擊行中的任何單元格來選擇行。除此之外，當他在同一行中再次單擊時選擇該行並隱藏細節時，我希望顯示每行的詳細信息。 那麼該怎麼做？

ASP.NET代碼：

<asp:GridView ID="resultGrid" runat="server" DataKeyNames="QuestionID" SelectedIndex="0" 
        AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" GridLines="None" OnSelectedIndexChanged="resultGrid_SelectedIndexChanged" Width="555px"> 
         <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> 
         <RowStyle BackColor="#F7F6F3" ForeColor="#333333" CssClass="generaltext" HorizontalAlign="Center" /> 
         <Columns> 
          <asp:CommandField ShowSelectButton="true" /> 
          <asp:BoundField DataField="QuestionID" HeaderText="Question" /> 
          <asp:BoundField DataField="UserAnswer" HeaderText="Your Answer" /> 
          <asp:BoundField DataField="Result" HeaderText="Result" /> 
         </Columns> 
         <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" /> 
         <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" /> 
         <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" CssClass="boldtext" /> 
         <EditRowStyle BackColor="#999999" /> 
         <AlternatingRowStyle BackColor="White" ForeColor="#284775" /> 
        </asp:GridView> 

後臺代碼：

public partial class Results : System.Web.UI.Page 
{ 
    bool bShowDetailsView; 

    protected void Page_Load(object sender, EventArgs e) 
    { 
     bShowDetailsView = false; 

     ArrayList al = (ArrayList)Session["AnswerList"]; 

     if (al == null) 
     { 
      Response.Redirect("default.aspx"); 
     } 

     resultGrid.DataSource = al; 
     resultGrid.DataBind(); 

     // Save the results into the database. 
     if (IsPostBack == false) 
     { 
      // Calculate score 
      double questions = al.Count; 
      double correct = 0.0; 


      for (int i = 0; i < al.Count; i++) 
      { 
       Answer a = (Answer)al[i]; 
       if (a.Result == Answer.ResultValue.Correct) 
        correct++; 
      } 

      double score = (correct/questions) * 100; 
      string username = HttpContext.Current.User.Identity.Name.ToString().Replace("ARAMCO\\", ""); 
      SqlDataSource userQuizDataSource = new SqlDataSource(); 
      userQuizDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["testConnectionString"].ToString(); 
      userQuizDataSource.InsertCommand = "INSERT INTO [UserQuiz] ([QuizID], [DateTimeComplete], [Score], [Username]) VALUES (@QuizID, @DateTimeComplete, @Score, @Username)"; 

      userQuizDataSource.InsertParameters.Add("QuizID", Session["QuizID"].ToString()); 
      userQuizDataSource.InsertParameters.Add("DateTimeComplete", DateTime.Now.ToString()); 

      // "N4" is for displaying four decimal places, regardless of what the value is 
      userQuizDataSource.InsertParameters.Add("Score", score.ToString("N4")); 

      userQuizDataSource.InsertParameters.Add("Username", username); 

      int rowsAffected = userQuizDataSource.Insert(); 
      if (rowsAffected == 0) 
      { 
       // Let's just notify that the insertion didn't 
       // work, but let' s continue on ... 
       errorLabel.Text = "There was a problem saving your quiz results into our database. Therefore, the results from this quiz will not be displayed on the list on the main menu."; 
      } 

     } 


    } 


    protected void resultGrid_SelectedIndexChanged(object sender, EventArgs e) 
    { 
     SqlDataSource1.FilterExpression = "QuestionOrder=" + resultGrid.SelectedValue; 
     bShowDetailsView = true; 
     answerDetails.Visible = bShowDetailsView; 
    } 



}

阿里，這是想要做一個平常的事和一個簡單的谷歌搜索會返回幾個關於如何實現它的優秀教程。

基本上，你可以將下面的代碼添加到您的RowDataBound事件：

if (e.row.RowType == DataControlRowType.DataRow) { 
     e.row.Attributes["onmouseover"] = 
      "this.style.cursor='hand';"; 
     e.row.Attributes["onmouseout"] = 
      "this.style.textDecoration='none';"; 
     // Set the last parameter to True 
     // to register for event validation. 
     e.row.Attributes["onclick"] = 
     ClientScript.GetPostBackClientHyperlink(CustomerGridView, 
      "Select$" + row.RowIndex, true); 
    }
