I have a console application in which we are creating xlsx files using OPENXML, we are able to create xlsx file & save it into specific folder in application.
But Now we want to show that file as a Save/Open dialog pop up. Then we can able to specify a particular path to save/ to open the existing files.
I am new to this OpenXml, Can anyone please help me on this to proceed further? How can I acheive this? Do we have any built-in DLL for this?
Thanks.
