The Format Builder dialog allows you to apply formating to the TextBox and
CheckBox items. You can open that dialog either from the property grid of those
items or from their context menu,
by selecting the Format menu item.
The expression values are handled differently depending on what
type of formatting you have assigned.For example, if you choose Currency formatting, Telerik Reporting will automatically
convert 3 into $3.00; if you choose Date formatting it would convert 3/1
to March 1; if you choose Percent formatting, it would change 0.3 to 30% etc.
If you want a format that is not included in the pre-made formats, you can make
your own custom format, using the Custom category. For example if you have a numeric field
that holds social security numbers, you can format it to look correct in the report
by specifying a custom format: ###-##-####.
Look through the list of Custom formats and try making some of your own.
