XtraTreeList（12）
工作中由于客户要求一些特殊节点的某一列必须控制其可编辑状态,所以通过查阅资料和自己的实践发现可以通过以下的步骤实现这样的要求,现把代码分享一下.
首先启用TreeList的ShowingEditor事件,该事件在控件转化到可编辑状态前调用,只要设置该事件的参数CancelEventArgs即可
而对于具体是哪一个节点则可以通过TreeList的FocusedNode来获取,而对于是哪一列则可以通过TreeList的FocusedColumn来获取
而我现在的这个项目还要求结合第一列的值来进行判断,那么就通过FocusedNode的GetValue(0)方法来获取第一列的值。
写了这么多还是来看一下代码可能更明白：
private void treeList1_ShowingEditor(object sender, CancelEventArgs e)
&&&&&&&&&&& TreeList currentTreeList = sender as TreeL
&&&&&&&&&&& if (currentTreeList != null)
&&&&&&&&&&& {
&&&&&&&&&&&&&&& TreeListNode node = currentTreeList.FocusedN
&&&&&&&&&&&&&&& DevExpress.XtraTreeList.Columns.TreeListColumn column = currentTreeList.FocusedC
&&&&&&&&&&&&&&& if (column.FieldName == &ITEM_VALUE& && node.GetValue(0).ToString() != &&)
&&&&&&&&&&&&&&& {
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& e.Cancel =
&&&&&&&&&&&&&&& }
&&&&&&&&&&&&&&& else
&&&&&&&&&&&&&&& {
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& e.Cancel =
&&&&&&&&&&&&&&& }
&&&&&&&&&&& }

J it only takes a minute:
I am having trouble binding stuff with
I want to create a custom cell template not the default one. When using the default cell template my binding works. Here is my project:
&Window x:Class="WpfApplication2.MainWindow"
xmlns="/winfx/2006/xaml/presentation"
xmlns:x="/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525"

&dxt:TreeListControl Name="treeList"&
&dxt:TreeListControl.Columns&
&!-- Custom Column --&
&dxt:TreeListColumn FieldName="Name" Header="Name"&
&dxt:TreeListColumn.CellTemplate&
&DataTemplate &
&TextBlock Text="{Binding Path=Name}" Foreground="Blue" /&
&/DataTemplate&
&/dxt:TreeListColumn.CellTemplate&
&/dxt:TreeListColumn&
&!-- default Column --&
&dxt:TreeListColumn FieldName="Position" Header="Position"/&
&/dxt:TreeListControl.Columns&
&dxt:TreeListControl.View&
&dxt:TreeListView Name="treeListView1" AutoWidth="True"
KeyFieldName="ID" ParentFieldName="ParentID"/&
&/dxt:TreeListControl.View&
&/dxt:TreeListControl&
Code Behind:
using System.Collections.G
using System.W
using System.Windows.D
namespace WpfApplication2
public partial class MainWindow : Window
public MainWindow ( )
InitializeComponent( );
treeList.ItemsSource = GetStuff( );
treeListView1.ExpandAllNodes( );
public static List&Employee& GetStuff ( )
List&Employee& stuff = new List&Employee&( );
stuff.Add( new Employee( ) { ID = 1 , ParentID = 0 , Name = "Gregory S. Price" } );
stuff.Add( new Employee( ) { ID = 2 , ParentID = 0 , Name = "Irma R. Marshall" } );
stuff.Add( new Employee( ) { ID = 3 , ParentID = 0 , Name = "John C. Powell" } );
stuff.Add( new Employee( ) { ID = 6 , ParentID = 2 , Position = "Brian C. Cowling" } );
stuff.Add( new Employee( ) { ID = 7 , ParentID = 2 , Position = "Thomas C. Dawson" } );
stuff.Add( new Employee( ) { ID = 8 , ParentID = 2 , Position = "Angel M. Wilson" } );
stuff.Add( new Employee( ) { ID = 9 , ParentID = 2 , Position = "Bryan R. Henderson" } );
stuff.Add( new Employee( ) { ID = 10 , ParentID = 3 , Position = "Harold S. Brandes" } );
stuff.Add( new Employee( ) { ID = 11 , ParentID = 3 , Position = "Michael S. Blevins" } );
stuff.Add( new Employee( ) { ID = 12 , ParentID = 3 , Position = "Jan K. Sisk" } );
stuff.Add( new Employee( ) { ID = 13 , ParentID = 3 , Position = "Sidney L. Holder" } );
stuff.Add( new Employee( ) { ID = 14 , ParentID = 1 , Position = "Brian C. Cowling" } );
stuff.Add( new Employee( ) { ID = 15 , ParentID = 1 , Position = "Thomas C. Dawson" } );
stuff.Add( new Employee( ) { ID = 16 , ParentID = 1 , Position = "Angel M. Wilson" } );
stuff.Add( new Employee( ) { ID = 17 , ParentID = 1 , Position = "Bryan R. Henderson" } );
public class Employee
public int ID { }
public int ParentID { }
public string Name { }
public string Position { }
why is it that my (&!-- Custom Column --&) does not display the Name of the employe? what do I have to do to bind it to that Property? If I remove the CellTemplate it works but I want to have my custom style...

Ok I'm going to answer before Devex Team :)
Change this :
&TextBlock Text="{Binding Path=Name}" Foreground="Blue" /&
&TextBlock Text="{Binding Path=Data.Name}" Foreground="Blue" /&
Or simply :
&TextBlock Text="{Binding Data.Name}" Foreground="Blue" /&
