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. In the below example, we pass the cell itself as a context to the igxTooltip and this way the tooltip has a direct reference to the necessary data. This is useful to display to users additional information about a cell or to provide to users an alternate description of the cell contents. In addition, you can handle the onTooltipShow event for every target (the cell) by updating the context property of the igxTooltip with any data that is relevant to the specific cell. You can override this behavior, however, to set ToolTip-text values for individual cells. This ensures the tooltip gets displayed even when no cell value is present.By default, ToolTips are used to display the values of DataGridView cells that are too small to show their entire contents. There are two ways to assign tooltips to cells in RadGridView, namely setting the ToolTipText property of a CellElement in the CellFormatting event handler. The value getter will return a value (an object) regardless of whether the value to display is empty or not. The column Athlete Col 2 uses tooltipValueGetter for the tooltip field.When there is no value (the first three rows) no tooltip is displayed. The column Athlete Col 1 uses tooltipField for the tooltip field.The first three rows have athlete values of undefined, null and '' (empty string).The example below shows both displaying and not displaying the tooltip for blank values. To achieve this, you should utilise tooltipValueGetter to return something different when the value is blank. For example, you might want to display a tooltip saying 'This cell has no value' instead.

This can be a problem if you wish a tooltip to display for blank values. In this case, it would be strange to show the tooltip with no value as that would show as a blank box.

This is the default behaviour as the simplest form of tooltip will show the value it is provided without any additional information. The grid will not show a tooltip if there is no value to show. The delays will have no effect if you are using browser tooltips, as they are controlled entirely by the browser.
