When you handle this event, getting the value of a cell ToolTipText property raises the event and returns the value of the DataGridViewCellToolTipTextNeededEventArgs.ToolTipText property as specified in the event handler. To avoid a performance penalty when working with large amounts of data, handle the CellToolTipTextNeeded event rather than setting the ToolTipText property of multiple cells. When you bind the DataGridView control to an external data source or provide your own data source by implementing virtual mode, you might encounter performance issues. References to the System and assemblies.
The CellFormatting event of the control must be associated with the event handler method shown in the example. With Me.dataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex)Ī DataGridView control named dataGridView1 that contains a column named Rating for displaying string values of one through four asterisk ("*") symbols. If e.ColumnIndex = Me.dataGridView1.Columns("Rating").Index _ Sub dataGridView1_CellFormatting(ByVal sender As Object, _īyVal e As DataGridViewCellFormattingEventArgs) _ ' Sets the ToolTip text for cells in the Rating column. Void dataGridView1_CellFormatting(object sender, Sets the ToolTip text for cells in the Rating column. If ( (e->ColumnIndex = this->dataGridView1->Columns->Index) Void dataGridView1_CellFormatting(Object^ /*sender*/, Set the DataGridViewCell.ToolTipText property. You can also disable the display of cell-level ToolTips by setting the DataGridView.ShowCellToolTips property to false. For example, if you have a row that displays status icons, you may want to provide text explanations using ToolTips. If the Viz in Tooltip is too large for the tooltip window, adjust the height and width of the target worksheet visualization. This is useful to display to users additional information about a cell or to provide to users an alternate description of the cell contents. You can override this behavior, however, to set ToolTip-text values for individual cells. I understand it is not possible to do it in iGrid.By default, ToolTips are used to display the values of DataGridView cells that are too small to show their entire contents.

That's the reason I asked you how to change font used in tooltip. Normally, the solution is to use monospaced font. It all works fine but sometimes - because font is not monospaced - the display in columns is not preserved which obviously doesn't look nice.
Symbols in second column are short so one "\t" is always enough. The issue of inserting an adequate number of tabs after first column of each row is solved. To make it simple, in the example above I put one "\t" after each name. In first column, there are names of different length. Each row consists of three pieces of information separated by tabs. Void iGrid1_RequestCellToolTipText(object sender, iGRequestCellToolTipTextEventArgs e)
In 'RequestCellToolTipText' event, when the user places the cursor into the cell and doesn't move it for some time, the multiline text similar to 'displayText' in the example below is generated and displayed. Tooltip text can be stationary or can move with the mouse pointer, called tracking. If you dont want to use the grids tooltip component, you can use the enableBrowserTooltips config to use the browsers default tooltip. They might or might not have a stem that points to the tools like a cartoon speech balloon. See the registering custom components section for details on registering and using custom tooltip components. That's my fault I haven't made myself clear enough from the very beginning. Tooltip controls can display a single line of text or multiple lines.
