How to set the default button in content page using asp.net?

Question

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.

How to handle this type of issue?

1) You simply have to do:

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

OR

2) Using 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:

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

I solved a similar problem with the following code.

Thx: http://www.w3schools.com/aspnet/prop_webcontrol_panel_defaultbutton.asp

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

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

    </asp:Panel>
</form>

The problem is with Master pages and content panels. This is ignored. – NINtender Feb 25 '16 at 19:23

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

Try this code

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

The above should use `btnSave.UniqueID` if there are containers involved (e.g. master pages). – BRass Jun 30 '17 at 15:50
