here in the below code EstbFee=0.00 and FutureEstbFee=4000.10 but when im trying to add these two it's resulting in "04000.1” rather it’s sum should display 4000.10 . How can solve it

C#

txtEstablishmentFee.Text = (Convert.ToDouble(dt.Rows[0]["EstablishmentFee"]) + Convert.ToDouble(dt.Rows[0]["FutureEstablishmentFee"])).ToString().Trim();

Thanks in advance

It's because you are actually concatenating two strings. Please note that you call ToString() on the second value. Try this:

C#

txtEstbFee.Text = (Convert.ToDouble(dt.Rows[0]["EstbFee"]) + Convert.ToDouble(dt.Rows[0]["FutureEstbFee"])).ToString().Trim();

Or better break into several steps:

C#

var estbFee = Convert.ToDouble(dt.Rows[0]["EstbFee"]);
var futureEstbFee = Convert.ToDouble(dt.Rows[0]["FutureEstbFee"]);
var totalFee = estbFee + futureEstbFee; 
txtEstbFee.Text = totalFee.ToString();

This way it's easy to read.

Stop playing with strings!
Try:

C#

txtEstbFee.Text = (Convert.ToDouble(dt.Rows[0]["EstbFee"]) + Convert.ToDouble(dt.Rows[0]["FutureEstbFee"])).ToString();

Or better:

C#

txtEstbFee.Text = ((double)dt.Rows[0]["EstbFee"] + (double)dt.Rows[0]["FutureEstbFee"]).ToString();

Assuming your columns are numeric. If they aren't, they should be!

You convert the second value to double and back to a string again. You need to surround it with braces or split up the line like below. Just replace value with a more meaningful name :)

C#

double value = Convert.ToDouble(dt.Rows[0]["EstbFee"]) + Convert.ToDouble(dt.Rows[0]["FutureEstbFee"]);
txtEstbFee.Text = value.ToString().Trim();

Good luck!

ps. why are the columns string instead of beeing a decimal type? Then no conversion is needed.
