[c#] right click context menu for datagridview

  • Put a context menu on your form, name it, set captions etc. using the built-in editor
  • Link it to your grid using the grid property ContextMenuStrip
  • For your grid, create an event to handle CellContextMenuStripNeeded
  • The Event Args e has useful properties e.ColumnIndex, e.RowIndex.

I believe that e.RowIndex is what you are asking for.

Suggestion: when user causes your event CellContextMenuStripNeeded to fire, use e.RowIndex to get data from your grid, such as the ID. Store the ID as the menu event's tag item.

Now, when user actually clicks your menu item, use the Sender property to fetch the tag. Use the tag, containing your ID, to perform the action you need.
