# What is better solution for validate form TextBoxs value?

In my [system](https://www.mindstick.com/articles/23411/the-most-effective-method-to-find-the-perfect-small-business-phone-system-for-your-business) has many [forms](https://www.mindstick.com/interview/34192/what-is-the-purpose-of-the-authentication-mode-forms-element-in-web-config) for [insert](https://www.mindstick.com/blog/173/executing-insert-delete-or-update-query-in-sqlserver-using-ado-dot-net) and edit [database](https://www.mindstick.com/articles/12226/use-of-database-in-sencha-extjs-and-insert-record-from-user-form-using-ajax) registers

But before to save [date](https://yourviews.mindstick.com/story/3869/propose-day-2024-exciting-date-ideas-for-you-and-your-partner) in database, I need [validate](https://www.mindstick.com/forum/33871/how-to-validate-email-address-in-javascript) any camp, validate it [values](https://www.mindstick.com/forum/327/sum-textbox-values) is empty or not, validate TextBox.Text lenght, etc...

I validated they with many many if's

if (tbName.Text.Equals("")) { }

if (tbPass.Password.Equals("")) { }

if (tbEmail.Text.Equals("")) { }

if (tbTelephone.Text.Equals("")) { }

if (tbNome.Text.Length < 4) { }

if (tbPass.Password.Length < 5) { }

if (!tbEmail.Text.Contains('@')) { }

but it is very no [efficiency](https://www.mindstick.com/articles/13091/12-tips-to-boost-your-studying-efficiency) and I don't know any other solution for this

What solution is usual for this?

Hi Ankita,

This is by hand so it will have some syntax errors

You will probably also want to implement iNotifyPropertyChanged

## Then Validation

```
public Class ValidatedText {    private string vText;    private bool valid = true;    Int23 maxLen = 0;    public bool Valid     {          get { return valid; }       set        {            if (valid == value) return;          valid = value;       }    }     public string Vtext     {         get { return vText; }       set        {            if (vText == value) return;          if (value.Len < 0)           {              Valid = false;             
            return;          }          // do additional validation here          vText = value;       }    }   public ValidatedText (string VText; Int32 MaxLen)   {   vText = Vtext; maxLen - MaxLen;   }}
```
