问题描述

嗨
我在gridview单元格中有一个按钮列表，现在我需要每个按钮在单击时执行不同的事件.我该如何解决?

我试图将其放在Page_Load上，但不起作用

Hi
I have a list of buttons inside my gridview cells, now i need each button to execute a difrent event when its clicked. how can i solve this?

I tried to put this on Page_Load but not working

foreach (GridViewRow rowItem in GridView1.Rows)
{
    Button btnMonday = (Button)(GridView1.Rows[0].Cells[1].FindControl("btnMonday"));
    btnMonday.Click += new EventHandler(this.mondae_Click);

    Button btnTuesday = (Button)(GridView1.Rows[0].Cells[2].FindControl("btnMonday"));
    btnTuesday.Click += new EventHandler(this.mondae_Click);
}

What should i do or where should i put it??

推荐答案

foreach (GridViewRow rowItem in GridView1.Rows)
{
    // why are you never using the ''rowItem variable ?
    Button btnMonday = (Button)(GridView1.Rows[0].Cells[1].FindControl("btnMonday"));
    btnMonday.Click += new EventHandler(this.mondae_Click);
 
    // why is the Button in Cell[2] named ''btnMonday'' ?
    Button btnTuesday = (Button)(GridView1.Rows[0].Cells[2].FindControl("btnMonday"));
    btnTuesday.Click += new EventHandler(this.mondae_Click);
}

因为您没有在循环中使用''rowItem变量，所以您的代码现在在Row [0]中设置相同的两个按钮，以具有同一事件处理程序的多个副本.

Because you do not use the ''rowItem variable in the loop, your code is now setting the same two buttons in Row[0] to have multiple copies of the same Event handler.

命令名称中的每个按钮添加不同的值
&在设计中，使所有按钮的单击事件按钮都是同一事件

然后在发生事件的情况下，单击尝试此代码

开关((((button)sender).commandname)
{
重视您的价值
执行代码
休息；
列出您的其他值
执行代码
休息；
}

for each button in the command name add different value
& in the design make the click event button for the all buttons is the same event

then in the event click try this code

switch (((button)sender).commandname)
{
case your value
execute code
break;
case your other value
execute code
break;
}
