1.获取当前被选中的节点数据
string tmp = treeL.FocusedNode.GetDisplayText(this.treeListColumnIndex);
2.是否允许编辑
treeList1.OptionsBehavior.Editable = false / true;
3.是否显示列头
treeList1.OptionsView.ShowColumns= false / true;
4.如何让TreeList的每个结点高亮显示
private void treeList1_CustomDrawNodeCell(object sender, DevExpress.XtraTreeList.CustomDrawNodeCellEventArgs e)
{
TreeList node = sender as TreeList;
if (e.Node == node.FocusedNode)
{
e.Graphics.FillRectangle(SystemBrushes.Window, e.Bounds);
Rectangle r = new Rectangle(e.EditViewInfo.ContentRect.Left,e.EditViewInfo.ContentRect.Top,
Convert.ToInt32(e.Graphics.MeasureString(e.CellText, treeList1.Font).Width + 1),
Convert.ToInt32(e.Graphics.MeasureString(e.CellText,treeList1.Font).Height));
e.Graphics.FillRectangle(SystemBrushes.Highlight, r);
e.Graphics.DrawString(e.CellText, treeList1.Font, SystemBrushes.HighlightText, r);
e.Handled = true;
}
}
5.是否显示树的级联虚线
LookAndFeel》UseDefaultLookAndFeel=false; && UseWindowsXPTheme=true;//显示 否则隐藏
6.选中具体节点触发的事件
FocusedNodeChanged
