Asp.net中自定义控件引用javascript中的日历脚本心得

<asp:TextBox  ID ="k" class="input" runat="server"  Text ="选择日期" runat="server"></asp:TextBox>

.aspx.cs引用的页面的代码：

string a = ((TextBox)Wcontrol1.FindControl("k")).Text;

Response.Write ("<script language='javascript'>alert('"+a+"');</script>");

主意：自定义控件中的TextBox必须是服务器端的否则得不到日期值！
