Set default button for Enter key (ASP.Net 1.1)
Posted by Clayton James on October 23, 2007
I was looking at solutions for an ASP.Net 1.1 application to set a default button for a control when the Enter key is pressed. I came accross Jeff’s solution which I thought was simple and provided the requirements I needed.
All I needed to do was add the one line below 🙂 This solution also allows you to wire up different default buttons to different form controls.
txtPropertyNo.Attributes.Add(“onKeyPress”, “javascript:if (event.keyCode == 13) __doPostBack(‘” + btnDisplayGraph.UniqueID + “‘,”)”);
You could also use the DefaultButton panel property.

I have been trying to make this work for a couple of hours and cannot get it working – Am I missing something (Using BN Net Framework 1.1)
Using two buttons and trying to get textbox1 to initiate a button2 response. Keeps going to button1 response. See Code Below:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
TextBox1.Attributes.Add(“onKeyPress”, “javascript:if (event.keyCode == 13) __doPostBack(‘” + Button2.UniqueID + “‘,”)”)
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = “button 1 clicked”
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Label1.Text = “Button 2 clicked”
End Sub
Thanks Barry

It seems that there was a syntax error in your code and it wouldn’t work in IE (only in FireFox). I’ve tweaked it a bit and now it seems to work correctly on both browsers.
txtLogin.Attributes.Add(“onKeyPress”, “javascript:if (event.keyCode == 13) {__doPostBack
(‘” + btnLogin.UniqueID + “‘);return false;}”);

The DefaultButton attribute doesn’t exist in ASP.NET 1.1 which is what this topic is about.
