i m working in asp.net4.0 with C#.in Appliction master page having 3 drop down control in want to take this value and fill my gridview but gridview are in other page

推荐答案

您可以通过多种方式进行此操作
首先
使用((dropdownlist)master.findcontrol [控件名称"]).selectedvalue

将其用于所有三个下拉列表

或
您可以将dropdownlist的selectedvalue存储在会话变量中
像这样

session ["firstdropdownlist"] = dropdownlist1.selectedvalue
像这样在其他下拉列表中

然后在页面上是必需的

if(session ["firstdropdown"]！= null)
{
字符串值= convert.tostring(session ["firstdropdown"])
}

there are serveral ways you can do this
first
use ((dropdownlist)master.findcontrol["name of your control"]).selectedvalue

use this for all your three dropdownlist

or
you can store selectedvalue of dropdownlist in session variable
like this

session["firstdropdownlist"] = dropdownlist1.selectedvalue
like this for other dropdownlists

and then on the page it is required

if(session["firstdropdown"] != null)
{
string value = convert.tostring(session["firstdropdown"])
}
