How do I make a form submit with a LinkButton?

Question

My login usercontrol has two text boxes and a linkbutton.

<asp:TextBox id="tbUserName" runat="server" size="10" />
<asp:TextBox id="tbPassword" runat="server" TextMode="Password" size="10" />

<asp:LinkButton Text="login" CssClass="submit"  runat="server" ID="lbLogin" OnClick="btnLogin_OnClick" />

I would like to call the "btnLogin_OnClick function when someone pushes enter on tbUsername or tbPassword.

How do I do this?

Here's a neat trick:

<asp:Panel ID="pnlLogon" runat="server" DefaultButton="lbLogin" Width="100%" >
        <asp:TextBox id="tbUserName" runat="server" size="10" />
        <asp:TextBox id="tbPassword" runat="server" TextMode="Password" size="10" />
        <asp:LinkButton Text="login" CssClass="submit"  runat="server" ID="lbLogin" OnClick="btnLogin_OnClick" />
</asp:Panel>

By wrapping the textboxes in a panel and setting the DefaultButton of the Panel to your LinkButton, any Enter in the text box inside the panel will cause the LinkButton Click to happen.

Thanks! This works in IE and Firefox but not chrome. Any ideas? – Nate Aug 27 '11 at 21:34

Brilliant, I had to follow the instructions in the link above for it to work in safari. Thank you. – Nate Aug 28 '11 at 00:50

// Code-behind

protected void btnLogin_OnClick(object sender, EventArgs e)
{
    if (Page.IsValid)
    {
        // process your form
    }
}

That function doesn't get called when someone pushes enter on tbUserName or tbPassword. It only get's called on click. – Nate Aug 27 '11 at 20:57
Sorry Nate, I misread the question. Either Mrchief's method should work. – IrishChieftain Aug 28 '11 at 00:32
