The number of selected UTF-8 characters in the edit box.

## Declaration

Source position: stdctrls.pp line 438

`public property TCustomComboBox.SelLength : Integer read GetSelLength write SetSelLength;`

## Description

SelLength is an Integer property which indicates the number of UTF-8-encoded characters selected in the edit box for the control. SelLength is used along with SelStart to determine the value in SelText.

Use SelStart to determine the position in Text for the selected value in the edit box for the control.

Use SelText to get the content selected in the edit box. Assigning a new value to SelText causes the value in SelLength to be updated.

SelLength is updated in the SelectAll method after the selection text is updated. It is also updated when KeyUp performs auto-completion for alphanumeric values entered in the control.
