Hi khanh dang,
Thank you for using Syncfusion controls.
By default, SizeGripper appears only when show the form using showDialog(). We have checked the same with MS Form also. But you can achieve this set the SizeGripperstyle for form.
|
var form = new Form1();
form.SizeGripStyle = SizeGripStyle.Show;
form.Show(); |
Please let us know if you need further assistance on this.
Regards,
