How can I get validators to work in ASP.NET?

How can I get validators to work in ASP.NET? - c#

I'm trying to implement validation in my ASP.NET Webforms application. Right now, the only validator that works is for the Date of Birth (DOB) field. It is a custom field.

What could be the problem that's causing this code not to work, yet is not throwing any errors? Also, I'd like to position the validators better, and add color to them?

You are using a ValidationGroup for all your validators except the DOB Custom validator.
Add it to your custom validator and also the Register Button.
<asp:CustomValidator runat="server"
ID="DateRangeCustomValidator"
ControlToValidate="DOBTextBox"
onservervalidate="valDateRange_ServerValidate"
ErrorMessage="Enter a valid date. "
ValidationGroup="RegistrationWizard"/>
<asp:Button ID="RegisterButton" runat="server" Text="Register"
ValidationGroup="RegistrationWizard" onclick="registerbutton_Click"/>

You have ValidationGroup set on your validators but not on your button.

How to control button from panel

I am new to ASP.NET. I have taken a Panel. Inside the Panel, I have taken a table. Inside the table there are TextBox, RadioButton and a Button controls.
I have written some code in button_click event.
But nothing happens. button_click event is not firing.
What to do now ?
I have also some other things in panel. But no click event is working.

If the button is in a datalist or gridview for example, set the CommandName property. The databound object (datalist, gridview) has ItemCommand-event. Put the code in this event.
Pseudo code:
if (e.CommandName.equals(your_command_name)){ label1.text = e.CommandArgument };

by default password textbox will not retail value on postback.so you need following ways to preserve value based on this link
protected void Page_Load(object sender, EventArgs e)
{
string pwd = txtPwd.Text;
txtPwd.Attributes.Add("value", pwd);
}

Limit to number of client-side validators on one aspx page?

I've got 5 required field validators on an aspx page.
With all validators active, none of the code behind any of the command buttons on the page will fire.
However, with ANY four out of five validators active, buttons all function ok.
Is there a limit to the amount of validators that can be used on a single page? Is there any other reason that this could be happening?
Help appreciated, thanks..
Daf.

Answer:
No there is no limit to validations on the page.
Misc:
Pranay has provided the fix in his answer.

In the end, I placed a second regular expression validator on one of the fields for testing.
When I removed this validator, problem ceased. Don't know how or why; any advice on this welcome..

You have ValidationGroup set on your validators but not on your button.
