Question

这就是我为按钮生成按钮和点击事件的方式。但是每次按下按钮都会点击它取最大值而不是点击按钮

       int noofquestions = 100;
        int k = 1;

        for (int i = 1; i <= noofquestions / 5; i++)
        {
            HtmlTableRow tRow = new HtmlTableRow();
            //TableRow tRow = new TableRow();          
            myTable.Rows.Add(tRow);
            for (int j = 1; j <= 5; j++)
            {
                HtmlTableCell tCell = new HtmlTableCell();            
                tRow.Cells.Add(tCell);
                Button link = new Button();
                //LinkButton link = new LinkButton();
                link.ID = "link" + k;
                link.Text = k.ToString();
                tCell.Controls.Add(link);
                ViewState["qno"] = k;

                link.Click += new EventHandler(link_Click);
                tCell.Controls.Add(link);

                //link.Click += new EventHandler(this.btn_click);

                k = k + 1;
            }
        }



        void link_Click(object sender, EventArgs e)
    {

    }

取决于你如何看待价值。

我认为我的意思是最大值你在质疑当你阅读ViewState [＆＃34; qno＆＃34;]时它是最大值，因为它是它设置的那个。

取而代之的是尝试从其他一些财产中读取。

void link_Click(object sender, EventArgs e)
{
    //If you do ViewState["qno"] it will be max value of K instead do following thing.  
}

//执行以下更新

    int noofquestions = 100;
    int k = 1;

    for (int i = 1; i <= noofquestions / 5; i++)
    {
        HtmlTableRow tRow = new HtmlTableRow();
        //TableRow tRow = new TableRow();          
        myTable.Rows.Add(tRow);
        for (int j = 1; j <= 5; j++)
        {
            HtmlTableCell tCell = new HtmlTableCell();            
            tRow.Cells.Add(tCell);
            Button link = new Button();
            //LinkButton link = new LinkButton();
            link.ID = "link" + k;
            link.Text = k.ToString();
            tCell.Controls.Add(link);
            ViewState[link.ID] = k;

            link.Click += new EventHandler(link_Click);
            tCell.Controls.Add(link);

            //link.Click += new EventHandler(this.btn_click);

            k = k + 1;
        }
    }



    void link_Click(object sender, EventArgs e)
{
        Button b = (sender)Button;
        string value = ViewState[b.ID].ToString();
}
