drawline permanently

[s4_sabahatf]

when we draw a line using grahics object,against button & when i refresh that window,the line disappears so i want to ask ,which method is used to permanent draw line

[quiteSmart]

sure it will disappear when u use the refresh method cz the refresh methode returns the form to its original view and dispose all its resources as if you are creating a new instance of that form. I am trying to figure out the solution for ur problem but i am not able to do so until now. jamil abou khalil

ok do one thing make one class level bool variable like private bool _drwaLineFlag=false; now on button click make it true(drwaLineFlag=true; ) and call the paint method this.Paint(); . and and in Paint Method put a condition against the _drwaLineFlag
