![]() ![]() The elements have custom CSS class attributes, but the default class names can also be used so that the tooltip gets the default styling.In this example the value of the title comes from which is the value for the Symbol column for the given row.The structure of the returned DOM is up to you.The effect of applying the tooltip renderer from the snippet above can be seen in the example below. ![]() You can process the raw values in the params object however you like before using them as a part of the returned HTML string. Other row data is provided in the context.data object inside the params object. The xValue and yValue for the highlighted data point as well as the reference to the raw datum element from the sparkline data array is provided in the params object. The tooltip renderer function receives the params object as a single parameter. I know this is an obscure problem, but perhaps the solution suggests for others a more general way of getting around things like this.Const tooltipRenderer = ( params ) => = params return ` 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.
