当我在母版页中使用通用保存按钮时发现错误 [英] Found an error when i use a common save button in master page

问题描述

我有一个母版页.然后我有几个内容页面，可以说我现在有2个内容页面cp1和cp2.
每个内容页面都有一个表单，该表单将具有一些用户输入，并具有一个SaveData()函数，该函数将数据保存到数据库中.

我想在母版页上保留一个通用的保存按钮.当打开cp1时，如果单击保存"按钮，则将保存cp1输入数据.
当打开cp2时，如果单击保存"按钮，则会保存cp2输入数据.

对于此解决方案，请在内容页面中使用以下代码，

I have a master page. Then i have several content pages, Lets say I have 2 content pages for now cp1 and cp2.
Each content page has a form that will have some user input and a SaveData() function that saves the data to a database.

I want to keep a common save button in the master page. when cp1 is opened if i click the save button then cp1 input data is saved.
when cp2 is opened if i click the save button then cp2 input data is saved.

for this solution is use the following code in content page,

Button btn = this.Master.FindControl("btnSave") as Button;
        
btn.Click +=new System.EventHandler(SaveData1);

然后我发现了一个错误:
No overload for SaveData1 matches delegate System.EventHandler

Then i found a error:
No overload for SaveData1 matches delegate System.EventHandler

How can i solve it??

推荐答案

SaveData1的格式如下:

The SaveData1 has the format as below:

void SaveData1(object sender, EventArgs e)
        {
            //Code to process your request
        }

SaveData1方法中的参数是什么.必须是

对象发件人和EventArgs e

SaveData1(object sender, EventArgs e)

What are the arguments are in SaveData1 method. It must be

object sender and EventArgs e like

SaveData1(object sender, EventArgs e)

System.EventHandler委托看起来像这样..

System.EventHandler delegate looks like this..

public delegate void EventHandler(Object sender, EventArgs e);
public event EventHandler NoDataEventHandler;

谢谢
