FormReport.aspx.cs

protected void addrow_Click(object sender, EventArgs e)
    {
        TextBox newtextbox = new TextBox();
        Panel panel1 = new Panel();
        panel1.Controls.Add(panel1);
    }

Answer 1

您可以使用HtmlGenericControl在面板内创建div或在父面板中添加面板

并添加一个样式，你可以使用control.Style.Add（＆＃34; style＆＃34;，＆＃34; value＆＃34;）

ASPX：或者您可以使用占位符

C＃

protected void addrow_Click(object sender, EventArgs e)
{
    Panel pnlEmployeeBox = new Panel();
    pnlEmployeeBox.CssClass = "pnlEmployeeBox";

    HtmlGenericControl columnLeft2= new HtmlGenericControl("div");
columnLeft2.CssClass = "column-left2";
        TextBox txt1 = new TextBox();
columnLeft2.Controls.Add(txt1);

pnlEmployeeBox.Controls.Add(columnLeft2);

 columnLeft2 = new HtmlGenericControl("div");

        txt1 = new TextBox();

    pnlEmployeeBox.Controls.Add(columnLeft2);

// and same goes for the dropdown list


}

我想创建控件并将它们定位到我想要的程序
