What is Serverside Validations and Clientside Validations [Resolved]

The client side validation runs in the browser where as server side validation runs on server. It actually check if the submitted data is correct or not. It is suggested that one should use both types of validation.
Clientside:
if ($(input[txtbox].val()== ''') {
alert('textbox value is mandatory') ;
return false;
}
else {
return true;
}
ServerSide:

protected void btn_OnClick(object sensder EventArgs e)
{
if(txtbox.text==string.empty)
{
lblerror.text="textbox value is mandatory";
}
else
{
//write your code here.................
}
}

Hi sravya
Asp.net has introduced a new type of validations controls which can validate controls both on the client side and server side.

1) In Client side validations the validations are performed by the client browser using client side script.
In server side validations the validations are performed by the server code developed in C# or VB.

2)Client side validations are not secured,where server side validations are secured.

3)Client side validations give quick response.

4)Client side validations are browser dependent but where as server side validations are browser independent.

5)Client side validation logic is having limited resources but where as server side validations logic contains more resources because any .NET language can be used.

Thanks & Regards

client side validation:
That means codes are executed by client side browser. Its not secure but executed faster than server validation. Its like client view type easily view the coding
open browser->right click the mouse->and then click view source
server side validation:
that means codes are executed in server. Just you submit your page and then your request send your server and then validate your page example asp.net validation controls. server side validation its a very secure type validation
Client are could not be view this code

hi sravya
client side validation is one which we do in the aspx page using javascript

function TextBoxDCountyClient(sender, args) {

    var v = document.getElementById('<%=TextBoxDTownCity.ClientID%>').value;

    if (v == '') {

        args.IsValid = false;  // field is empty

    }

    else {

        // do your other validation tests here...

    }

}

server side validation is one which we do validation in the code behind

protected void TextBoxDTownCity_Validate(

    object source, ServerValidateEventArgs args)

{

    string v = TextBoxDTownCity.Text;

    if (v == string.Empty)

    {

        args.IsValid = false;  // field is empty

    }

    else

    {

        // do your other validation tests here...

    }

}
