DevExpress控件的使用(二)

接上篇.

10.treeView为tree节点加右键菜单并选中该节点       private void treeList1_MouseDown(object sender, MouseEventArgs e)       {           if (e.Button == MouseButtons.Right)           {               DevExpress.XtraTreeList.TreeListHitInfo hi =treeList1.CalcHitInfo(e.Location);                if (hi.Node != null &&hi.Node.ImageIndex == 5) //叶子节点的ImageIndex== 5                {                    TreeListNode node =treeList1.FindNodeByID(hi.Node.Id);                    treeList1.FocusedNode =node;                    this.popupMenu1.ShowPopup(MousePosition);                }           }       }treeList间的拖放，如从treeList1拖一个节点到treeList2上的一个节点上。 1.将treeList1的DragNodes属性设为true treeList1.OptionsBehavior.DragNodes = true; 2.treeList2的事件处理： private void treeList1_DragEnter(objectsender, DragEventArgs e){     e.Effect = DragDropEffects.Copy;} private void treeList1_DragDrop(objectsender, DragEventArgs e){     object obj = e.Data.GetData(typeof(TreeListNode));     DevExpress.XtraTreeList.TreeListHitInfo hi =treeList1.CalcHitInfo(treeList1.PointToClient(new Point(e.X, e.Y)));     TreeListNode newNode = treeList1.AppendNode(new object[] {((TreeListNode)obj).GetValue(this.treeListColumn1) }, hi.Node);     newNode.Tag = ((TreeListNode)obj).Tag;            } private voidtreeListForm_CustomDrawNodeCell(object sender,DevExpress.XtraTreeList.CustomDrawNodeCellEventArgs e){         if(e.Node.Checked)         {                   e.Appearance.Font= new Font(DevExpress.Utils.AppearanceObject.DefaultFont, FontStyle.Bold);         }} //勾选节点的限制private voidtreeListGroup_BeforeCheckNode(object sender,DevExpress.XtraTreeList.CheckNodeEventArgs e){         if(e.Node.ImageIndex == USERICON)         {                   e.CanCheck= false;         }         else         {                   e.CanCheck= true;                   //三种勾选状态只使用勾选/不勾选                   e.State= (e.PrevState == CheckState.Checked ? CheckState.Unchecked :CheckState.Checked);         }} 11.XtraTabControl DevExpress.XtraTab.XtraTabControlxtraTabControl = new DevExpress.XtraTab.XtraTabControl();//添加TabxtraTabControl.TabPages.Add("page1");//清空TabPagextraTabControl.TabPages.Clear();//设置TabPage不可见xtraTabControl.TabPages[i].PageVisible =false;//设置TabPage不可用xtraTabControl.TabPages[i].PageEnable =false;//设置TabPage下的控件不可用xtraTabControl.TabPages.Controls[i].Enable= false;12.RadioButton/CheckBoxDevExpress.XtraEditors.CheckEdit//设置类型Properties.CheckStyle = Standard/Radio/...//设置一组单选按钮Properties.RadioGroupIndex设置为同一个数字13.ColorEditDevExpress.XtraEditors.ColorEdit//设置是否显示系统颜色和Web颜色Properties.ShowSystemColors = false;Properties.ShowWebColors = false;//取选中颜色值Color color = int i = colorEdit1.Color;//换算成int型，便于保存到文件int i = colorEdit1.Color.ToArgb();14.LayoutControl//多个layoutcontrol选中后右键-Group可将所选控件置为一组this.layoutControlGroup1.Expanded = true;//展开组，设为false为折叠组this.layoutControlGroup1.ExpandButtonVisible= true;//使折叠按钮可见this.layoutControlGroup1.ExpandOnDoubleClick= true;//双击展开、折叠组//TextVisible属性设置Item前方的文字说明，一般设为false15.GridControl//绑定数据 protected override void InitMDBData(stringconnectionString) {    DataSet ds = new DataSet();    System.Data.OleDb.OleDbDataAdapter oleDbDataAdapter = newSystem.Data.OleDb.OleDbDataAdapter("SELECT * FROM " + tblName,connectionString);    oleDbDataAdapter.Fill(ds, tblName);    gridControl1.DataSource = ds.Tables[tblName];    gridControl1.MainView.PopulateColumns();}//可以添加自定义EmbededNavigator的CustomButtons：this.efDevGridOth.EmbeddedNavigator.Buttons.CustomButtons.AddRange(newNavigatorCustomButton[] {  new NavigatorCustomButton(5, "保存"),  new NavigatorCustomButton(6, "返回")                });//设置Grid的Style，对应行的新增/修改状态：private void gridView1_RowStyle(objectsender, RowStyleEventArgs e){ try {  if(this.gridView1.DataRowCount < 1) return;  if(e.RowHandle < 0)  {  return;  }  if(((DataRowView)this.gridView1.GetRow(e.RowHandle)).Row.RowState ==DataRowState.Modified)  {  e.Appearance.Font = new Font(e.Appearance.Font, FontStyle.Bold);  }  if(((DataRowView)this.gridView1.GetRow(e.RowHandle)).Row.RowState ==DataRowState.Added)  {  e.Appearance.ForeColor = Color.Red;  } } catch (Exception ex) { this.EFMsgInfo = ex.Message; }}16.LookUpEditor//绑定数据efDevLookUpEditType.Properties.DataSource =dataSet1.Tables[0efDevLookUpEditType.Properties.Columns.Add(newDevExpress.XtraEditors.Controls.LookUpColumnInfo("CODE"));efDevLookUpEditType.Properties.Columns.Add(newDevExpress.XtraEditors.Controls.LookUpColumnInfo("CODE_DESC_1_CONTENT"));efDevLookUpEditType.Properties.ValueMember= "CODE";efDevLookUpEditType.Properties.DisplayMember= "CODE_DESC_1_CONTENT";efDevLookUpEditType.EditValue =dataSet1.Tables[0].Rows[0]["CODE"];
