Question

我正在开发一个Master-Details GridView＆amp; DetailsView控件。一切都运行良好，但我希望它删除我在GridView中的每一行中的选择按钮，并使用户能够通过单击行中的任何位置或通过单击行中的任何单元格来选择行。除此之外，我希望在他选择行时显示每一行的详细信息，并在他再次点击同一行时隐藏详细信息。 那怎么做？

ASP.NET代码：

<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>

代码隐藏代码：

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，这是一个常见的事情，一个简单的谷歌搜索将返回几个关于如何实现它的优秀教程。

基本上，您可以将以下代码添加到RowDataBound事件中：

    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); 
    }
