Property Value

An integer specifying the number of characters in the current selection in the TextBox. Getting this property returns the number of characters in the current selection. Setting this property adjusts the length of the current selection to the specified value, keeping the beginning of the selection fixed. The default value is zero (0).

Exceptions

Exception type	Condition
ArgumentOutOfRangeException	Raised if the specified selection length is negative.

Remarks

In general, when a specified selection length causes the selection to end in an invalid position (i.e. between a carriage return and a new-line character, in a tag, etc), the selection length automatically adjusts so that the resulting selection starts and ends in valid positions.
