请指导我如何在用户控制中使用多个下拉选择索引更改事件



这里我在用户控件里面有3个下拉菜单



我使用的代码如

Hi all

Pls Guide me how to use multiple drop down selected index changed event in user control

Here i have 3 drop down inside the user control

I used a code like

protected void ddlCustomerGroup_SelectedIndexChanged(object sender, EventArgs e)
{
    customer();
}

 public class SelectedIndexChangedEventArgs : EventArgs
    {
    }

如何包含第二个下拉选择的索引已更改



我完成了代码，例如

How to include the second drop down selected index changed

I done the code like

protected void ddlCustomer_SelectedIndexChanged(object sender, EventArgs e)
       {
           customer();
       }

但我发现dis message错误



编译器错误消息：CS1061：'ASP.custgrpprodcatproduct_ascx'不包含'ddlCustomer_SelectedIndexChanged'的定义，并且没有可以找到接受类型'ASP.custgrpprodcatproduct_ascx'的第一个参数的扩展方法'ddlCustomer_SelectedIndexChanged'（您是否缺少using指令或汇编参考？）





请指导我解决问题..

But i found dis message as error

Compiler Error Message: CS1061: 'ASP.custgrpprodcatproduct_ascx' does not contain a definition for 'ddlCustomer_SelectedIndexChanged' and no extension method 'ddlCustomer_SelectedIndexChanged' accepting a first argument of type 'ASP.custgrpprodcatproduct_ascx' could be found (are you missing a using directive or an assembly reference?)


pls Guide me to fix dis issue..
