如何在使用Cascading DropDown Extender时在WebMethod中传递更多参数? [英] How to pass some more parameters in WebMethod while using Cascading DropDown Extender ?

问题描述

大家好，

我正在使用AJAX级联下拉菜单扩展器，并制作了一个正在运行的虚拟示例.使用Web服务的第二个下拉列表基于第一个下拉列表的选择进行填充.但是，应该填充第二个下拉列表的实际查询在sql查询的"where"子句中具有更多约束，并且该值太动态了(我不能认为其值是静态的).因此，我也需要在我的网络方法中使用该变量的值.

请帮助如何在该Web服务中获取其他参数.

谢谢.

Hi all,

I am using AJAX Cascading dropdown extender,and i have made a running dummy example.Using web service second dropdown is filled based on the selection of first drop down. But actual query that should fill second drop down have some more constraints in ''where'' clause of the sql query, and that''s value is too dynamic that (i cannot assume its value to be static). So i need that that variable''s value in my web method too.

please help how to get additional parameters in that web service .

Thanks.

推荐答案

您不能向现有对象进行的调用中添加参数.您必须自己编写.

You can''t add parameters to a call that is made by an existing object. You''d have to write your own.
