Need help in typecasting string in to int

Question

I am using Convert.ToInt32(ddlBuyer1Country.SelectedValue); to typecast a string returned by selectedvalue. But this is giving me 0 instead of 3. I have selected value as 3 in this case.

Answer 1

Convert will return a 0, if the value is null.

Are you sure SelectedValue is not null before calling Convert?

How are you using the ddlBuyer1Country?

Answer 2

Try: Int.TryParse(ddlBuyer1Country.SelectedValue, out myInt);

But double check to make sure that you are not re-binding the dropdown on postback, that could reset your selected value to 0. Make sure the dropdown bind only occurs in a:

if(!Page.IsPostBack)
