Hi

i'm sorry for a novice question, but i have lokked for a solution for quite some time now

I have a small usercontrol, where I made a simple calulation for test purpose.

If I put the user control on a page which are not under "Role based protection", everything works perfectly.

But when the user control is under on a page which are under "Role based protection" this is whats happens:

The first time i click the submit button, the onclick event wont fire. The page loads and its a postback.

Second time I click the submit button It works perfectly. 

The user control is in a template and the button is in <form runat="server"> <form> tag

.ascx code:

Amount
<asp:TextBox ID="txtAmount" runat="server" />
<asp:Button ID="btnSubmit" Text="Submit" runat="server" OnClick="btnSubmit_Click" />
<br />
<asp:Label ID="lblResult" runat="server" />

Code behind:

       protected void btnSubmit_Click(object sender, EventArgs e)
        {
            double GST = 1.25;
            double Result;
            Result = double.Parse(txtAmount.Text) * GST;
            lblResult.Text = Result.ToString("0.00");
        }

It's in Umbraco v6.0.5

Any help or advice will be helpful because this is dragging too much now and I really need to complete.

Thanks
