thanks GURU. till yet with your help  map can be saved now with area selected by me  i am trying to add some text on it now . i need more help from you i have attached the updated work  just review it . kindly help me regarding following topics 1. Prevent to Overwrite/ Overdraw on already selected lines (for this either on paint event i should take array which hold positions of already drawn lines and on mouse / paint / event i should check that either lines are already drawn .) 2. Erase lines / selection 3. enlarge particullar selection best Regards

Polygons are not a control. You will have to save all the points to a file on disk To do this you could use serialization http://blog.csharphelper.com/2010/12/17/use-xml-serialization-to-save-and-restore-pictures-drawn-by-the-user-in-c.aspx To enlarge you could copy a rectangle slightly bigger than your polygon into a picturebox that has sizemode set to stretched To delete or edit unsure till I get further information Tackle one part at a time -ie: Do the saving polygons first then upload your project so we can work out a way to edit

thanks for giving me your time. thanks for your guidance. 1.how can i edit (enlarge  particular sketched area  delete ). 2. I need to save what ever i draw on picture box so for doing that i did this private void button1_Click(object sender EventArgs e) { Control.ControlCollection coll = this.Controls; foreach (Control c in coll) { if (c != null) MessageBox.Show(ControlName+c.Name.ToString()+ - Location X =+c.Location.X.ToString()+Location Y=+c.Location.Y.ToString()); } } above code does not recognize polygons as control object. as i need to save the location and with their object name ..how can i do that.? Regards
