Asp.net button doesn't submits disabled controls, even with submitdisabledcontrols="true"

Question

Hi,

I have a page with some disabled controls, it looks like this

<form id="form1" runat="server" submitdisabledcontrols="true">
    <asp:UpdatePanel ID="upp" runat="server">
        <ContentTemplate>
            <asp:TextBox ID="textbox1" runat="server"  AutoPostBack="True" ontextchanged="textchaged_handler" />        
            <asp:TextBox ID="textbox2" runat="server" />
        </ContentTemplate>
    </asp:UpdatePanel>
    <asp:ImageButton ID="ibVerify" runat="server" OnClick="btnVerify_Click" ImageUrl="~/img/imagebutton.png" AlternateText="Verify" />
</form>

Programatically, the second textbox is disabled with some server side code, during initialization.

The problem is that, even setting submitdisabledcontrols="true" in the form tag, the disabled textbox value isn't submited to the server when I click the ImageButton. I checked this with firebug, and also in VS, where the old value is retrieved.

When I press TAB in the first textbox, however, the second textbox value gets posted, no matter submitdisabledcontrols is set or not...

Any ideas?

Hey,

That form attribute states that "Gets or sets a Boolean value indicating whether to force controls disabled on the client to submit their values.", so I think you need to use the client-side disabled property, not the server-side ENabled property, as in:

<asp:TextBox .. disabled="disabled" />
