在默认页面中执行事件和在母版页中执行另一个事件时发生冲突 [英] Conflict in executing an event in Default page and another event in Master page

问题描述

我有一个ASP.NET Web表单项目，在主页面中我有一个按钮（searchButton），我在searchButton_Click事件中编写了一个代码，点击Go按钮后（如果用户在文本框中键入内容，按Enter键），用户将被重定向到另一个页面（FrmSearchResult.aspx）

  public   partial   class  Site1：System.Web.UI.MasterPage 
 { 
 受保护  void  Page_Load（ object  sender，EventArgs e）
 {
} 
 
  protected   void  searchButton_Click（ object  sender，EventArgs e）
 {
 Session [  nameA] = s earchText.Text; 
 Response.Redirect（  FrmSearchResult.aspx）; 
 Session.RemoveAll（）; 
} 
} 
} 

我还有Default.aspx页面，其中提到了母版页！

在默认页面中我有一个文本框（searchUniTextBox），我在searchUniTextBox_ValueChanged事件中实现了一个代码！

  protected   void  searchUniTextBox_ValueChanged（ object  sender，EventArgs e）
 {
  string  searchUni = searchUniTextBox.Text.ToLower（ ）; 
  string  [] uniItem =  new   string [CheckBoxList1.Items.Count]; 
  for （ int  i =  0 ; i <  CheckBoxList1.Items.Count; i ++）
 {
  if （CheckBoxList1.Items [i] .Text.ToLower（）。Contains（searchUni））
 CheckBoxList1.Items [i] .Selected =  true ; 
} 
} 
 

但问题是每当用户按下Enter键时，此事件（searchUniTextBox_ValueChanged）执行，并且紧接着那个searchButton_Click在主页面执行!!!!!

我不知道如何阻止在主页面中执行searchButton_Click事件，当searchUniTextBox_ValueChanged事件触发时？

谢谢你这么多

解决方案

在按钮属性集中

 UseSubmitBehaviour =false

I have a ASP.NET Web Form Project, in the master page I have a button(searchButton), I wrote a code in searchButton_Click event, after clicking on "Go" button (also if user types something in the textbox and press Enter key), user will be redirected to another page(FrmSearchResult.aspx)

    public partial class Site1 : System.Web.UI.MasterPage
    {
        protected void Page_Load(object sender, EventArgs e)
        {
        }

        protected void searchButton_Click(object sender, EventArgs e)
        {
            Session["nameA"] = searchText.Text;
            Response.Redirect("FrmSearchResult.aspx");
            Session.RemoveAll();
        }
    }
}

I also have Default.aspx page which has mentioned master page!
In the default page I have a textbox (searchUniTextBox), and I implemented a code in searchUniTextBox_ValueChanged event!

protected void searchUniTextBox_ValueChanged(object sender, EventArgs e)
       {
           string searchUni = searchUniTextBox.Text.ToLower();
           string[] uniItem = new string[CheckBoxList1.Items.Count];
           for (int i = 0; i < CheckBoxList1.Items.Count; i++)
           {
               if (CheckBoxList1.Items[i].Text.ToLower().Contains(searchUni))
                   CheckBoxList1.Items[i].Selected = true;
           }
       }

But the problem is that whenever user presses Enter key, this event (searchUniTextBox_ValueChanged) executes, and immediately after that searchButton_Click in the master page executes!!!!!
I do not how I can prevent executing searchButton_Click event in the master page, when searchUniTextBox_ValueChanged event fires??
Thank you so much

解决方案

In the button properties set

UseSubmitBehaviour="false"
