推荐答案

在用户控件内创建一个属性，就像这样

Create A property inside your User Control Like this

public string mySelectedValue
{
  get
  {
     return ddlControl1.SelectedValue.toString();
  }
}

在您使用UserControl的页面中访问属性，例如

access the property in your page where you are using the UserControl like

string strValue = UserControl1.mySelectedValue;

如果要访问客户端(在Javascript/jQuery内部)的控件，请执行以下操作

If you want to access the control at Client end (inside Javascript/jQuery), do the following

protected void Page_Load(object sender, EventArgs e)
{
    ClientScript.RegisterStartupScript("strCtrlID","'" + ddlCtrl.ClientID + "'");
    //Rest of your page load logic.
}

document.getElementById(strCtrlID);
