I am working through the e-commerce chapter (ch. 13) and am trying to format the Price and Total columns in the shopping cart display. I have DataFormatString for those two columns set to "{0,c}". I have tried other values too, but nothing that I do changes the display. It's always without the leading dollar sign and without the zero for cents for a number like "7.9". How do I format the column values such as what I'm describing?

Is the value you are trying to format a string or a double??

Normally I do something like this:

String.Format("{0:c}", Convert.ToDouble("7.5"));

hth.

Thank you for your response.

In the Shopping class, there is a variable called "_LineTotal" which is a Double. This has been added as a Field to a GridView control. When I Edit Columns for the GridView and select this field, I have entered "{0:c}" in the DataFormatString property. I'm not sure where to use the sample line you put in your message, since I'm not formatting the column in code but in a control's properties. I would appreciate any further help you can give me.
