Easy Question how do I format Text to Currency

[nerdalert1]

I have a datagrid where I have a "DataFormatString="{0:#,##0.00}" as the format of the column. I am using CDbl to total columns with a .ToString at the end to fill a textbox. How can I make this the same format so lets say 10000 comes up 10000.00 thanks all.

textbox.text = String.Format("{0:C}", 10000.0)

Getting this error:


Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

I got it to work. Do you happen to know how I can on the update of a textbox or the lost focus call a Total routine in my code behind? I already have a validator on the box checking for currency. But now I need to call a Totl routine on each box.

Set the autopostback property for the textbox to true. And then write code in the textbox_onchange event.
