Master Pages, buttons, Login Control, and the default button

Tuesday, August 14, 2007

I've been working on a MasterPage that has a search box and search button.

When the master page loads in the Login page, the default button is set to the search button. This is not good when a user wants to press "Enter" on the username/password textbox.

I tried to do this:

<asp:Panel ID="pnlLogin" runat="server" DefaultButton="LoginButton">

<asp:Login ID="lgnSecurity" OnAuthenticate="lgnSecurity_Authenticate" runat="server" />

</asp:Panel>

However, that didn't work and I got parser errors. I was playing and finally came up with this, which works perfectly.

lgnSecurity.Focus();
((HtmlForm)Master.FindControl("MainForm")).DefaultButton = ((Button)lgnSecurity.FindControl("LoginButton")).UniqueID;

The problem is with the Panel.DefaultButton that the panel calls FindControl on itself, and not on your login control as you do in your workaround.

Not sure how much of a hack, but the FindControl uses $ or : as path separator to "look deeper" in the control tree, so for me it works fine with the following DefaultButton string:

Thanks! It save me a lot of trouble to figure it out.
