Property Value

Type: System::Int32
The maximum number of characters that can be manually entered into the text box. The default is 0, which indicates no limit.

Identifier field

MaxLengthProperty

Metadata properties set to true

None

You can use this property to restrict the length of text entered in the control for values such as postal codes and telephone numbers. You can also use this property to restrict the length of text entered when the data is to be stored in a database so that the text entered into the control does not exceed the maximum length of the corresponding field in the database.

This property does not affect characters that are added programmatically.

When this property is set to 0, the maximum length of the text that can be entered in the control is limited only by available memory.

The following example shows how to create a TextBox with a MaxLength of 500 characters.
