Hello Friends,
For dynamically adding textboxes I used Page.parseControl method.
For this method i send following string

String sb="<asp:TextBox ID="txtF_Loanamount" CssClass="text_box_FillData" runat="server" backcolor="#FFC0C0" onchange="ok();" ></asp:TextBox><asp:RegularExpressionValidator ID="RegularExpressionF_Loanamount" runat="server" CssClass="RequiredFieldValidatorCSS" ControlToValidate="txtF_Loanamount" Display="Dynamic" ErrorMessage="<br />Please enter Number only" SetFocusOnError="True" ValidationExpression="[-+]?^[1-9]([0-9]*\.[0-9]+|[0-9]+)*"></asp:RegularExpressionValidator>
"
in my cs file i write
Control ctrl = Page.ParseControl(sb.ToString());
Panel1.controls.add(c);

as in txtF_Loanamount if i enter charators then it show message that
"Please enter Number only"
It works fine if my application is on windows XP

but when i put this in Windows Server 2003 (SP 2)

then it don't shows any error message and that wrong value is saved on button click
so please help me to solve this problem

Thanks,
Sanjiv

This is a weird way to add a control to a page, but setting that aside...

Have you actually looked at the rendered HTML/JavaScript from the problem version (WS 2003) vs. the good version (XP) to see where and how they differ?

It's very hard to tell from what you've posted, but I can see there are a lot of quote marks inside that string. Could you have improperly escaped one or more of them? Have you tried using the @ escape character on that string?

Just throwing out a few possibilities...

Hello Lee

Thanks for your quick replay

but if we copy paste that string in aspx page than it show correct controls and validator forget that javascript onchange function.

How can I see that

"endered HTML/JavaScript from the problem version (WS 2003) vs. the good version (XP)"

please help me to solve this problem

How about doing a View | Source from the browser?
