怎样在DevExpress XtraTreeList中设置ToolTip？

Answer 1

您可以使用ToolTipController控件，然后通过ToolTipController.GetActiveObjectInfo事件来设置ToolTip关键代码：private void toolTipController1_GetActiveObjectInfo(object sender, DevExpress.Utils.ToolTipControllerGetActiveObjectInfoEventArgs e) { if (e.SelectedControl is DevExpress.XtraTreeList.TreeList) { TreeList tree = (TreeList)e.SelectedControl; TreeListHitInfo hit = tree.CalcHitInfo(e.ControlMousePosition); if (hit.HitInfoType == HitInfoType.Cell) { object cellInfo = new TreeListCellToolTipInfo(hit.Node, hit.Column, null); string toolTip = string.Format("{0} (Column: {1}, Node ID: {2})", hit.Node[hit.Column], hit.Column.VisibleIndex, hit.Node.Id); e.Info = new DevExpress.Utils.ToolTipControlInfo(cellInfo, toolTip); } }}点击下载示例 本站文章除注明转载外，均为本站原创或翻译
