推荐答案

下面的示例代码将在运行时添加一个按钮网页。修改它以满足您的要求。

Below sample code will add a button on runtime in you web page. Modify it to meet your requirements.

private void AddButton(int id)
{
//Initialize button and set its properties (especially ID)
Button bt = new Button();
bt.ID = "btn" + id.ToString();
bt.Text = "Text"+id.ToString();
//Attach click event
bt.Click += new EventHandler(bt_click);
//Change below line (this) with the container in which you want your button to appear.
this.Controls.Add(bt);
}

点击事件处理程序将是：

Click event handler will be:

protected void bt_click(object sender, EventArgs e)
{
    Button btn = sender as Button;
    //Add your functionality here
}

在您的页面添加面板..

Add panel to your page..

public partial class WebForm1 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Table tb = new Table();

        for (int i = 0; i < 5; i++)
        {
            TableRow tr = new TableRow();

            for (int j = 0; j < 5; j++)
            {
                TableCell tc = new TableCell();
                Button bt = new Button();
                bt.Height = 10;
                bt.Width = 10;
                tc.Controls.Add(bt);
                bt.Click += bt_Click;
                tr.Cells.Add(tc);

            }

            tb.Rows.Add(tr);
        }

      Panel1  .Controls.Add(tb);
    }

    void bt_Click(object sender, EventArgs e)
    {
        Response.Write("hello");
    }
}

protected void Page_Load（object sender，EventArgs e）

{



表tbl =新表（）;

phl.Controls.Add（tbl）;

数组array = new Array [25];

随机rndm = new Random（）;

int n = rndm.Next（）;

string [] a = new string [25];





for（int i = 0; i< 5; i ++）

{



TableRow tbr = new TableRow（）;

for（int j = 0; j< 5; j ++）

{

TableCell tbcl = new TableCell（）;

Button bt = new Button（）;

ListItem ls = new ListItem（）;

ls.Text.Contains（ls.Text）;

bt.Text = ls.Text;

ListBox lb = new ListBox（）;

lb.Items.Add（ls）;

ls.Text = rndm.Next（1,25）.ToString（）;



tbcl.Controls.Add（bt）;



tbr.Cells.Add（tbcl）;



}





}

}

}

}

protected void Page_Load(object sender, EventArgs e)
{

Table tbl = new Table();
phl.Controls.Add(tbl);
Array array = new Array[25];
Random rndm = new Random();
int n = rndm.Next();
string[] a = new string[25];


for (int i = 0; i < 5; i++)
{

TableRow tbr = new TableRow();
for (int j = 0; j < 5; j++)
{
TableCell tbcl = new TableCell();
Button bt = new Button();
ListItem ls = new ListItem();
ls.Text.Contains(ls.Text);
bt.Text = ls.Text;
ListBox lb = new ListBox();
lb.Items.Add(ls);
ls.Text = rndm.Next(1, 25).ToString();

tbcl.Controls.Add(bt);

tbr.Cells.Add(tbcl);

}


}
}
}
}
