Hello! The title is misleading kinda haha. Anyways, I have a client that wants me to build them an application that uses DataGridView but wants a popup to happen whenever they click a cell. Like they are a store, they want to keep track of customer credit but whenever they click their name, they want to add a note of what they bought. Here is an image to help describe what I mean: Name: Capture.PNG Views: 1143 Size: 2.6 KB Where it says Popup here or whatever, like a little overlay that they can add when press exit or an X or whatever? They want those notes to be linked to that specific cell and that is something I have no idea how to do, which is why I have come here. All help is awesome!
