I’m relatively new to C# and Windows forms so excuse me for what may seem like an easy question.
I have a windows application which has a dialog box which when opened contains textboxes with some default values. These can be changed depending on what the user wants to use. The values in this dialog box together with the content on the main form are then used to create an XML file. The issue I have is if I go to open the dialog box again to change any values in the same session, the original values are there and not any of the new values.
How do I get it to keep the values that have been changed in that particular session?
If you want to see the user’s values the next time you open the dialog box, you’ll need to save those values somewhere, and then re-load them the next time the dialog is displayed (usually on Form_Load or Form_Show). And of course you’ll need to save the values (probably in Form_Close?) before exiting.
Where you save those values is up to you. You can save them in some static variables in the form class if you want it to be just for that run of the program. Or you can store in a configuration file, the registry, isolated storage, etc. if you want to re-load those settings the next time the program is run.
