Re: user should have to enter 4 numbers in textbox after 4 numbers textbox should not take any number

The TextBox has a "MaxLength" attribute. It does exactly what you want.

That won't quite do it. The OP said NUMBERS. Your solutions will only limit the length but still allow any character to be entered.

Ok then, I missed the "numbers" part of the question. But then this can easily be taken into account by adding a compare validator that checks for the type.

No, a compare validator works by comparing the value of one field to another. It, or any validator, also does not prevent characters from being entered when only numbers are expected. Validators check the input afterward, they don't prevent entry.

Ok I agree on the second part. However, a compare validator can be used to check for data types

<asp:CompareValidator ID="" ControlToValidate="" Operator="DataTypeCheck" Type="Integer" runat="server" ErrorMessage="Must be Int"></asp:CompareValidator>

Once again, this is after the fact. It does not prevent entry. Thanks for playing.

In which I said that you were right.
What I was replying to was the first part of your statement "No, a compare validator works by comparing the value of one field to another"

Using a masked edit texbox you can restrict the input to a specific lenght and type. Search for the term and you will find many examples from custom server controls to JavaScript solutions. Pick one that will work for you.

You can use the MaxLength attribute of the textbox to limit the lengh to 4 and use this function to limit the input to only numbers. If you want to restrict entry of invalid characters, you'll have to handle the keypress event and write appropriate code.

JavaScript

function isNumeric(str)
{
	var i=0;
	for(i=0;i<str.length;i++)
	{
		if(str.charAt(i) < '0' || str.charAt(i) > '9')
			return false;
	}
	return true;
}

There are far better examples and implementations than this.

I understand, but for a starter, this should be okay.

Moreover, by redirecting new users to pre-written frameworks and controls, we're actually discouraging them from learning the language itself.

No.

.NET is a pre-written framework, has it discouraged you from learning? JQuery is a framework, have you stopped learning JavaScript?

Lazy coders may not want to learn any further than how to use an API but true developers will learn and better themselves. Expereinced developers also know to not recreate the wheel, if there is a perfectly good framework or control to do what is needed they will use it and save the time for more complex problems.

Correct. But the OP doesn't seem to be an experienced guy. So, let him learn the language first.

Inexperienced will not take the time for in-depth learning. Most employers don't pay for training or to have their devs learn something, they want results.

                if (i % 2 != 0)
                    panel.rows[i].style.display = 'none';

I can infer from this code that you are trying to hide even rows from a table. A little debugging can help you. Why don't you try putting alerts at various places to find out if the various pieces of code are really executed or not.

Hi guys

I am creating some radio buttons at run time and also declaring its java script checked function,
and providing it the name parameter coming from my entity's name property , but problem is this name
contains such characters which generates client side error while creating radio button and its event , I cannot correct the data as my client needs these characters in their names , is there any way to solve this problem ?

What characters are those? Can you show some code? Why don't you strip those characters from the name? And why does your client dictate what names you should give to your UI elements? It is none of his business.

no ,client does not dictate my control names,for examle
i have a class
{
string id;
string name;
}

so while creating radio button at run time to its radioncheck event i am passing
name as parameter , so if name contains some invalid characters (which i cannot strip out)
so java script fails to create radion button at run time.
