tabindex attribute for asp.net server-side panel control not being translated in client side

In my asp.net project I have a panel control that has the TabIndex attribute set. Example:

<asp:Panel ID="myPanel" runat="server" TabIndex="0"></asp:Panel>

My expectation is that when the code was converted to client side that it would look like this:

<div id="myPanel" tabindex='0'></div>

But when I view the source on the client side I see no tabindex attribute at all. It is as if ASP.Net ignored the tabindex attribute.

Why is the attribute not translated?

Solution

  • It is being removed because TabIndex="0" is the default (meaning no tab order) for asp.net web controls. Even though tabindex="0" is valid for the div that asp.net panels get converted to on the client side, TabIndex="0" will not be translated. The TabIndex must be 1 or greater to be translated.
