You can programmatically read or set the value of a CheckBox Web server control.

Note
If you are working with a CheckBoxList control, the procedure for getting and setting the value of a check box is different. For details, see How to: Determine the Selection in List Web Server Controls.

To get or set CheckBox Web server control selection

Get or set the CheckBox control's Checked property. A value of true means the check box is selected.

Note

Testing the value of a check box does not tell you if the user changed the value of the control, only if it is selected.

In the following example, if the check boxchkCanWeSendEmailis not selected, the check boxchkSendInHTMLFormatis automatically cleared as well.
```
If chkCanWeSendEmail.Checked = False Then
   chkSendInHTMLFormat.Checked = False
End If
```
```
if(chkCanWeSendEmail.Checked == false){
   chkSendInHTMLFormat.Checked = false;
}
```
