Error with converting string to double

[jcb1269]

Hello all,

I'm using ASP.Net and I'm doing the following:

object.Amount = CDbl(txtAmount.text)

When txtAmount.text = "", (no value entered into it) I get the following error:

System.InvalidCastException: Cast from string "" to type 'Double' is not valid.

How do I fix this without defualting the textbox to 0?

Thanks..

Jim

Try using Val or Double.TryParse instead of CDbl, or add a RequiredFieldValidator to the field.

Or catch the error and handle it.
