Above code is server side code - what is the issue? Why have you tagged it Javascript? What are you looking for - it's not clear. Please rephrase/update question using 'Improve question' link.

Hi,

Your code will just concatenate the strings, it will not give sum.
Try:

C#

int no1 = Convert.ToInt32(txtOSIInterstFromBank.Text);
int no2 = Convert.ToInt32(txtOSITDSFromBank.Text);
int no3 = Convert.ToInt32(txtOSIInterestFromDebent.Text);
int no4 = (no1 + no2 + no3);

txtOSITotalIncome.Text=no4.ToString();

Happy Coding :)

Hello

Not a really clear question but:
If you want javascript in content page then:
call Page.ClientScriptManager.RegistgerClientScriptBlock in content page

And if your problem is Sum of tree textboxes then you need to Pars their value to int or double or ...
for example

C#

int number1 = 0;
int number2 = 0;
int number3 = 0;
int.TryParse(OSIInterstFromBank.Text, out number1);
int.TryParse(txtOSITDSFromBank.Text, out number2);
...

Solution 1

string + string = stringstring  SumOfStrings<br />
int + int + int = SumOf3int<br />
number + number = SumOf2numbers

Do you see what i'm trying to "tell" you?

To add 3 numbers you need to declare number variable, then convert it into string.
