I want to know which button a user clicked. I want to get the invoice number which is the text for the button control. But how do I know which row the user clicked?
I have a single event handler for multiple buttons. By default, the label says player 1 and when a button is clicked, the label changes to player 2. How would I go on having it go back and forth between player 1 and player 2 when a button is clicked until one of them wins? Preferably in C#.
I have a column that I don't want to display but I still want to access its value. the other problem is that I can't access the value of a cell because it contains a label. Does someone know how to access the text in that label?
Do you know if it's possible to add a button in a gridview that when clicked, downloads a document listed in the gridview to a specific location, and then opens the document that was just downloaded? (It's too many steps for the users to right-click, do a file save as, save the document, and then open it). So, I need to accomplish a lot with this little button. Also, I'd need to specify a directory on the C drive to save it too.
