我需要设置content page默认按钮。我的代码是这样的:

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent" 
defaultbutton="BtnSearch" defaultfocus="TxtSearchValue">

It is working fine, but my master page menu have one image button like chat, I can press the enter key to fire image button click event but it does not fire default button in content page.

它工作的很好，但是我的master page菜单上有一个image按钮，比如chat，我可以按下enter键来触发image按钮点击事件，但是在content page中它没有触发默认按钮。

1) You simply have to do:

你只需要做:

this.Form.DefaultButton = this.btnId.UniqueID;

或

2) Using Javascript:

2)使用Javascript:

function clickButton(e, buttonid)
{

  var evt = e ? e : window.event;

  var bt = document.getElementById(buttonid);

  if (bt)
  {
      if (evt.keyCode == 13)
      {
            bt.click();
            return false;
      }
  }
}

And from the code behind:

后面的代码:

ContentPage.Attributes.Add("onkeypress", "javascript:return 
clickButton(event,'" + btnSearch.ClientID + "');");

Wrap all the asp.net controls and buttons inside the Panel and set default button property of panel with the id of a button.

将所有asp.net控件和按钮封装在面板中，并设置带有按钮id的面板的默认按钮属性。

this.Page.Form.DefaultButton = btnSave.ID;
