推荐答案

你好

这不是一个很明确的问题，但是:
如果要在内容页面中使用javascript，则:
在内容页面中调用Page.ClientScriptManager.RegistgerClientScriptBlock

如果您的问题是树文本框的总和，则需要将其值解析为int或double或...
例如

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

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

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

您看到我要告诉"您的内容吗?

要添加3个数字，您需要声明数字变量，然后将其转换为字符串.

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.

您的代码只会连接字符串，不会给出总和.
试试:

Hi,

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

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();

快乐编码:)

Happy Coding :)
