How to insert form data into a database with validations in asp.net? -

i trying build web application requires users register themselves. added custom validators , other validators according need.

part of code in .aspx file

<form id="form" name="form" action="../hi.aspx" method="post"> <table cellspacing="4" class="style1"> <tr> <td class="style4"> <asp:textbox id="txtfirstname" runat="server" width="157px"></asp:textbox> </td> td class="style5" id="fname"> <asp:customvalidator id="customvalidator1" runat="server" controltovalidate="txtfirstname" errormessage="your first name should @ to the lowest degree 2 characters long" onservervalidate="customvalidator1_servervalidate" forecolor="red" validateemptytext="true"></asp:customvalidator>...

and correspnding code in .aspx.cs file is

protected void customvalidator1_servervalidate(object source, servervalidateeventargs args) { args.isvalid = (args.value.length>1); }

this works fine when run part of application.

now, want retrieve values of text fields , store them in database.

in aspx.cs file, wrote code as

protected void buttonregister_click(object sender, eventargs e) { string fname = txtfirstname.text; controllers.registrationcontroller r = new controllers.registrationcontroller(); int = r.registerdata(fname); if (a==1) { response.redirect("../hi.aspx"); } }

which called when submit button clicked.

the registerdata() method in registrationcontroller established connection database , stores form values. connection established correctly , values retrieved , stored. but, problem is, when phone call registerdata() method method buttonregister_click, validation have written doesn't work. entered in form gets stored database without validation.

how retrieve values , store them , @ same time ensure beingness validated?

i new .net, help appreciated.

thank much in advance.

you phone call page.validate within click method , check result of or specifying causesvalidation on button should cause valdation run

in long term though might want @ moving rules lower lower (ie. business logic) such when/if move supporting services wont have reimplement rules in services, of course of study if you're not ever planning getting away them on ui may suffice

asp.net validation
