The GridControl allows you to display tooltips (hints) when end users move the mouse over particular visual elements, such as column headers, band headers or data cells.

Expanded Column and Band Header Tooltips

If the BaseColumn.HeaderToolTip property is not specified, a tooltip is displayed for a column (band) header if its caption is clipped. A tooltip contains the text displayed within a column or band header.

Custom Tooltip Text

To specify custom text for the tooltip of an individual column or band, use the BaseColumn.HeaderToolTip property. In this case, the tooltip displays automatically when an end-user hovers the mouse pointer over the column's header.

Custom Tooltip Template

Use the BaseColumn.HeaderToolTipTemplate property to specify the tooltip presentation for an individual column. To specify a common tooltip template applied to all columns displayed within a view, use the DataViewBase.ColumnHeaderToolTipTemplate property.

Expanded Tooltips for Trimmed Text

The in-place editor trims the text when this text overflows the content area in display mode.

The text is trimmed only if the TextEditSettings.TextWrapping property is set to System.Windows.TextWrapping.NoWrap.

Use the TextEditSettings.TrimmedTextToolTipContentTemplate property to specify a template that is used to present the tooltip content.

To hide tooltips for the trimmed text, set the TextEditSettings.ShowTooltipForTrimmedText property to false.

Expanded Cell Tooltips

You can define the Cell Tooltip template for cells:

To define cell tooltips via templates within a column, specify the template binding using the BaseColumn.CellToolTipBinding property.

The code sample below demonstrates how to define cell tooltips via templates.


The cell tooltip template defined via the DataViewBase.CellToolTipTemplate property is not in effect if the cell tooltip template is defined using the BaseColumn.CellToolTipTemplate property.
