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

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 content when it overflows the content area in display mode.

It does not perform text trimming unless the TextEditSettings.TextWrapping property is set to System.Windows.TextWrapping.NoWrap. The template, used to present the content of the tooltip, is specified via the TextEditSettings.TrimmedTextToolTipContentTemplate property.

Expanded Cell tooltips

You can define the cell tooltip template for cells:

To define cell tooltips via templates within a column, you need to define 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.
