推荐答案

请讲清楚

Hi,

please come to the point

Page 1

//Create & Build a String Array from the grid column values
string[] arrEmp = { "Emp101", "Abraham Lincoln", "Male", "50" };
//Add the array to Session
Session.Add("arrEmp", arrEmp);

Page 2

//Create & Build a String Array from Session
string[] arrEmpDetails = (string[])Session.Item("arrEmp");

//Assign the values to controls from Array
txtEmployeeID.Text = arrEmpDetails(0);
txtEmployeeName.Text = arrEmpDetails(1);
txtEmployeeGender.Text = arrEmpDetails(2);
txtEmployeeAge.Text = arrEmpDetails(3);

如果您有任何疑问，请告诉我

取决于需求/安全性/性能/UI实现，可以有多种方法将数据从一页传递到另一页.

其中一个会话已在答案之一中进行了解释.您还可以使用查询字符串，Cookie等(适用于整个页面的各种其他状态管理技术)来传递值.

除此之外，在ASP.NET2.0中添加了一个名为"PreviousPage"的新功能.这是基于UI实现的.单击左右按钮后，将一页发布到另一页-在这种情况下，您可以访问上一页控件，因此有值.

跨页面发布以获取更多详细信息. [

Depending on the requirement/security/performance/UI implementation, there can be various ways to pass on data from one page to other.

Session being one of them already explained in one of the answers. You can also pass on the values using querystring, cookies, etc (various other state management techiniques that are applicable across the pages)

Adding to all that, In ASP.NET2.0 a new feature called ''PreviousPage'' was added. This is something UI implementation based. Posting one page to another after a button click or so - in this scenario you can access the previous page controls and thus there values.
