How to set the default button in content page using

I need to set the content page default button. My code is like this:

<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.

Method 1

1) You simply have to do:

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


2) Using Javascript:

function clickButton(e, buttonid)

  var evt = e ? e : window.event;

  var bt = document.getElementById(buttonid);

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

And from the code behind:
ContentPage.Attributes.Add("onkeypress", "javascript:return 
clickButton(event,'" + btnSearch.ClientID + "');");

Method 2

I solved a similar problem with the following code.


<form runat="server">
    <asp:Panel runat="server" DefaultButton="bt1">

        <asp:TextBox runat="server" />
        <asp:Button id="bt1" Text="Default" runat="server" />


Method 3

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

Method 4

Try this code

protected void Page_Load(object sender, EventArgs e)
        this.form1.DefaultFocus = txtSearch.ClientID;
        this.Form.DefaultButton = btnSearch.UniqueID;

Method 5

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