带回发的ImageButton [英] ImageButton with Postback

问题描述

你好



是否可以在ASP.NET上为ImageButton进行回发



我想要的是当用户没有点击我的图像按钮时，什么都不会发生。



编辑

OK为了进一步解释，我有一个ASP页面，它有2个Imagebutton，每个按钮都有一个用户控件查询数据库。



ImageButton1 - >查询分支

ImageButton2 - >查询分支机构的员工



每次单击ImageButton2，搜索分支机构的员工并选择它，我想知道为什么它进入ImageButton1。所以，我打算在ImageButton1上使用isPostBack条件，这样它就不会触及ImageButton1的过程

Hello

Is it possible to make a Postback for a ImageButton on ASP.NET

What I want is when User didn't click my Image button nothing will happen.

EDIT
OK to explain it further, I have a ASP page which have 2 Imagebutton each button had a user control which query on the database.

ImageButton1 -> Query the Branches
ImageButton2 -> Query the Employee of the branch

Every time I Click ImageButton2, search the Employee of the Branch and Select it, I was wondering why It enters on ImageButton1. So, Am planning to use isPostBack condition on ImageButton1 so that it will not touch the process of ImageButton1

推荐答案

检查这些条件

- -----------------------

条件1：

Check these conditions
-------------------------
Condition 1 :

 protected void Page_Load(object sender, EventArgs e)
{

if(!IsPostBack)
{
// *Set the Initial Loading conditions, Call the Function that needs to be called on first Page Load* //
FirstLoad();

// *If you failed to add this Condition, Page Will load the FirstLoad() each time round trip Occures* //
}


}
Private void FirstLoad(){

// *First Load* //
}

protected void ImgButton1_Click(object sender,EventArgs e)
{
// *Button Click Event* //
}

protected void ImgButton2_Click(object sender,EventArgs e)
{
// *Button Click Event* //
}

条件2 ：

您需要检查两个图像按钮的OnClick事件，有时您可能为两个按钮提供相同的事件

Condition 2 :
You need to check the OnClick Event of two Image Buttons, Some time You may provided the same event for two buttons
