I just missed to say that I can use ImageButton instead to resolve it….

Try this code

protected ImageButton saveimage;

imagecell=new TableCell();
imagecell.Width=new Unit(5,UnitType.Percentage);
this.Controls.Add(imagecell);
AddressSaveImageCell=new TableCell();
AddressSaveImageCell.Width=new Unit(5,UnitType.Percentage);
this.Controls.Add(AddressSaveImageCell);
