TOOLTIP WINDOWS GRID HOW TO
I know this is an obscure problem, but perhaps the solution suggests for others a more general way of getting around things like this.The following code example shows how to set the ToolTipText property within an event handler for the CellFormatting event. So, I've declared a new Button, set Visible = false, added it to the DGV's controls, and used it in the ToolTip.Show call. But the location of that Button canĬhange, which is, I suspect, why the location of the ToolTip varied. To get around that, I replaced "this" with a Button that I declare and use within the derived DGV. The result was that no ToolTip displayed. Initially, I tried using "this" as the value of that parameter since I'm invoking ToolTip.Show from within a derived DataGridView to which the The issue is connected with the 2nd (IWin32Window) parameter of the ToolTip.Show call. I found my problem and thought I'd post the result in case anyone else finds it helpful. Any idea why I would get a different Location for some DGVs versus others? I'm posting my DGV settings I am doing this within my derived DataGridView via an override of the OnCellMouseEnter event handler and mirroring your code. To the right and below where I would expect. That's what happens for some of my DGVs, but for others it displays I changed the X and Y coordinates in the ToolTip.Show call to be cellRect.X and cellRect.Y + so the ToolTip would display directly below the cell. For some of my DGVs, it works as expected, but for others, the ToolTip displays in a Location that's different than what I expect. When I switch to a variation of your approach, I am getting what I want, though not always. Thus, the ToolTip no doubt displays over the cell intentionally. After having reviewed again some of the documentation on doing that, I saw that this ToolTip is designed to display cell values that won't fit in the cell rectangle. Your reply prompts me to explain my DataGridView is derived and that I was displaying the ToolTip by setting the DGV's ShowCellToolTips property to true and then supplying the text for the ToolTip via an override of the OnCellToolTipTextNeededĮvent handler.
