This example demonstrates how to display truncated text in a resizable ASPxGridView column and show a full value as a tool tip.
1) Apply the following CSS class to column cells:
[CSS].truncated{white-space:nowrap;overflow:hidden;text-overflow:ellipsis;}
[ASPx]<dx:GridViewDataTextColumnFieldName="Description"VisibleIndex="2"><CellStyleCssClass="truncated"></CellStyle></dx:GridViewDataTextColumn>
2) Handle the ASPxGridView.HtmlDataCellPrepared event to set tool tips for the same DataCell via the e.Cell.ToolTip property.
