in my web page there r more-than 50 text-boxes. Each textbox is used to fill the answer of paricular sums. These Texboxes are divided into 5 rows.That means 10 textbox in a row. Each Row Texbox has a single value. Each row contains 10 sums. For Example first row sum textbox value is 2 . ie from texbox1 .....textbox10 the answer is 2. If we type 2 in textbox1 then our correct answer is 1. If we type 2 in textbox1 to textbox10 then our correct answer is 10.if we type any wrong answer then it will b counted as wrong answer( for example if i type 3 for textbox5 ans. then my overall calculation for texbox1 to texbox10 ll b "CORRECT ANSWER =9 , WRONG ANSWER=1 ). This what i have to do for my whole Rows.

Now what i have to do in this page is when i finished my sums i have to get total "CORRECT ANSWER and WRONG ANSWER" for 5 row sums. That means 50 text box values.. I have to perform this in a button click. For 10 texboxes wat i did was

C#

int _correct = 0;
int _wrong = 10;

if (txtbox1.Text == "5")
       {
           _correct++;

       }

       if (txtbox1.Text == "3")
       {
           _correct++;
       }
.
.
.
.
.
.
int _wrongfinal = _wrong - _correct;
        lblCorrextAnswer.Text = _correct.ToString();
        lblWrongAnswer.Text = _wrongfinal.ToString();

For 50 texbox i think this is not a good method. Can i do this with loop method?. How can i do that? Should i use Tabindex for looping?

On your HTML add text box with correct value to check

<asp:textbox id="TextBox1" runat="server" valuetocheck="4" xmlns:asp="#unknown"></asp:textbox>

This is how to do it through loop.
form1.Controls here form1 is the name of control that contains the textbox controls. You can adjust the conditions accordingly.

C#

int _correct = 0;
int _wrong = 0;


foreach (Control cntrl in form1.Controls)
{
    if (cntrl.GetType().Name == "TextBox")
    {
        TextBox txt = (TextBox)cntrl;
        string Valuetocheck = txt.Attributes["valuetocheck"];
        string GetInputValue = txt.Text;

        if (Valuetocheck == GetInputValue)
        {
            _correct++;
        }
        else
        {
            _wrong++;
        }
    }
}
