Question

This seems to be a common problem but I cannot find a solution.

I type in my username and password which are in a login control I have created. I then press enter once I’ve typed in my password and the page just refreshes. It triggers the page load event but not the button on click event.

If I press the submit button then everything works fine.

Answer 1

using your forms default button is correct, but you need to supply it the correct id as it will be rendered to HTML.

so you do as Jon said above:

<form runat='server' DefaultButton='SubmitButton'> 

But ensure you use the Button name that will be rendered. You can achieve this my making the Button public in your control, or a method that will return it’s ClientId.

Let’s say your button is called btnSubmit, and your implementation of your control ucLogin.

Give your form an id

<form runat='server' id='form1'> 

Then in your page load in your code behind of your page, set the DefaultButton by handing it your button client id.

protected void Page_Load(object sender, EventArgs e) {    form1.DefaultButton = ucLogin.btnSubmit.ClientID; }
