Updating access database datagridview
You can enter only currency values in this type of field.Also, you do not have to manually enter a currency symbol.You can enter large amounts of text and numeric data in this type of field.Also, if the database designer sets the field to support rich text formatting, you can apply the types of formatting that you normally find in word processing programs, such as Office Word 2007.When you design a database table, you select a data type for each of the fields in that table, a process that helps ensure more accurate data entry.For example, suppose you specify the Number data type for a field because you need to calculate sales figures.For more information about using rich-text formatting in a Memo field, see the article Format data in rows and columns.Like Text fields, you can also run conversion functions against the data in a Memo field.
In addition, those objects must adhere to a set of design principles or the database will either work poorly or fail altogether.
A text field accepts a smaller number of characters than does a Memo field — from 0 to 255 characters.
In some cases, you can use conversion functions to perform calculations on the data in a Text field.
If you format the field to show a list, you can select either Yes or No, True or False, or On or Off from the list, again depending on the format applied to the field.
You cannot enter values in the list or change the values in the list directly from a form or table.
