Format Dialog Box (Number Tab) (Report Builder 1.0)
Use the Number tab of the Format dialog box to specify how numerical and date values appear within a selected cell or data region. Options change depending on which value type is being formatted.
Note
If you find that formatting options you want to use are grayed out, it means that the field's data type, which is located in the data source, and the formatting options are not compatible. For example, if the field contains numeric values but the field's data type is "string", numerical data formatting options, such as currency or decimals, cannot be applied and the numerical formatting options are grayed out.
