问题描述

我有一个嵌套的Master Page.First Master和Main Master，这个下拉列表在First Master上，我需要在服务器事件的页面值中从DataBase parent.document.getElementById（'MDDL_Dept'）获取数据。值





谢谢，

I had a Nested Master Page.First Master and Main Master and this dropdown is on First Master i need its value in page for server event for fetching data from DataBase parent.document.getElementById('MDDL_Dept').value


Thanks,

推荐答案

尝试在文档中证明两个masterpages contentplace holder id .getelemntbyid

ie document.getElementById

（'Contentplaceholderidofmainmaster_contentplaceholderidoffirstmaster_MDDL_Dept'）。value

try proving both masterpages contentplace holder ids in socument.getelemntbyid
i.e document.getElementById
('Contentplaceholderidofmainmaster_contentplaceholderidoffirstmaster_MDDL_Dept').value

获取母版页控制我们需要得到首先控制然后使用它

to get master page control we need to get the control first and then used it

var dropdown=(DropDownList)Master.FindControl("MDDL_Dept");
            if (dropdown != null)
            {
                //you code
                string yourvalue = dropdown.SelectedValue;
            }
