我如何得到asp：面板默认按钮发射按钮单击事件？

Question

我有三个asp网络文本框，将包含搜索表的搜索条件。我希望搜索能像谷歌一样工作。按下回车键以激活“Enter”按钮上的点击事件。点击事件从不会触发。我能做些什么来让它着火？

这里是后台代码方法：

protected void EnterKeyPressed_Click(object sender, EventArgs e) 
    { 
     ReloadData(); 
     this.Multiview1.ActiveViewIndex = 0; 
    } 

Answer 1

退房这个问题和答案，如果它可以帮助：Default button not working in asp.net panel

的DefaultButton被用来捕捉Enter按键，如果焦点已经在面板内部，例如，您必须将焦点移至输入字段，如面板内的文本框。如果焦点不在那里，它将无法工作。

快速浏览，你尝试过在这里假取出回报：

$("#<%=SVParentCategoryLinkTitle.ClientID %>").keydown(function (e) { 
    if (e.which == 13) { 
     __doPostBack("#<%=EnterKeyPressed.UniqueID %>", ""); 
     return false; 
    } 
})
