Printable View
I am using the defaultvaluesneeded event to set the default values of a new row, however these values are not being set until I actually click the empty new row. I want the default values to be filled out before the user clicks the new row, is this possible?
If there is not new row created than where you want to set the default values?
When datagridview is in edit mode at the bottom there is normally an empty row. Since I have image columns this empty row displays the image not found icon and I would prefer it displays a blank cell (new bitmap(1,1)), simply because it looks nicer, may seem trivial but I would appreciate help.
That last row isn't supposed to contain data. You'll notice that as soon as you start entering data another empty row is created. I don't know but I would guess that if you tried to display an image in that cell it would constitute entering data and trigger a new row to be created.
This is a bit of speculation as I've never done this myself but I would think that you'd have to handle the CellPainting event or the like and, if it's an image cell in the shared row, then customise its appearance so it doesn't display that icon.
