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?

It's an error focus not the Default button..@bUKaneer – Abdias

Answer 1

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 + "');");

The problem is with Master pages and content panels. This is ignored. – Doucet

Answer 3

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;
    }

Variant

Answer 5

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

The above should use btnSave.UniqueID if there are containers involved (e.g. master pages). – Avellaneda
