**1、treeList不显示父级子级结构，如grid使用**

属性：
    Options->OptionsView 下的 ShowPreview:True，ShowRoot：False
    数据 下的 KeyFieldName:ID,ParentFiledName：ID。

去掉选择列：OptionsView下的 “ShowIndicator=false”

checkbox父子联动：treeList1.OptionsBehavior.AllowRecursiveNodeChecking="true"

# **2、绑定GridLookUpEdit** #

public static void BindGNLB(GridLookUpEdit txtGNLB)
            {
                txtGNLB.Text = "";
                txtGNLB.Properties.View.OptionsBehavior.AutoPopulateColumns = false;
    
    
                BLL.KZ_GNLB bll = new BLL.KZ_GNLB();          
    
    
                DataTable dt = bll.GetList("", "PXH");
    
    
                txtGNLB.Properties.DataSource = dt;  //数据源
                txtGNLB.Properties.DisplayMember = "GNMC"; //绑定Text显示的字段源名称
                txtGNLB.Properties.ValueMember = "GNID"; //绑定Value字段源名称
    
    
                txtGNLB.Properties.AllowNullInput = DevExpress.Utils.DefaultBoolean.True;
                txtGNLB.Properties.View.BestFitColumns();
                txtGNLB.Properties.ShowFooter = false;
                txtGNLB.Properties.View.OptionsView.ShowAutoFilterRow = true; //显示不显示grid上第一个空行,也是用于检索的应用
                txtGNLB.Properties.View.OptionsFilter.AllowFilterEditor = false;
                txtGNLB.Properties.AutoComplete = false;
                txtGNLB.Properties.ImmediatePopup = true;
                txtGNLB.Properties.PopupFilterMode = DevExpress.XtraEditors.PopupFilterMode.Contains;
                txtGNLB.Properties.TextEditStyle = DevExpress.XtraEditors.Controls.TextEditStyles.Standard; //配置,用于像文本框
            }

开启 text检索

txtGNLB.Properties.DisplayMember = "DISPLAY"; //绑定Text显示的字段源名称

DevExpress.XtraGrid.Columns.GridColumn colBH = new DevExpress.XtraGrid.Columns.GridColumn();
                DevExpress.XtraGrid.Columns.GridColumn colMC = new DevExpress.XtraGrid.Columns.GridColumn();
               // DevExpress.XtraGrid.Columns.GridColumn colYWM = new DevExpress.XtraGrid.Columns.GridColumn();
                DevExpress.XtraGrid.Columns.GridColumn colDisplay = new DevExpress.XtraGrid.Columns.GridColumn();            
    
    
                setGridColumn(colBH, "编号", "BH", "colBH", 100);
                setGridColumn(colMC, "科室", "MC", "colMC", 100);
                //setGridColumn(colYWM, "音位码", "YWM", "colYWM", 100);
                setGridColumn(colDisplay, "DISPLAY", "DISPLAY", "colDisplay", 100);
                colDisplay.Visible = false;
    
    
                gridLookUpEdit.Properties.View.Columns.AddRange(new DevExpress.XtraGrid.Columns.GridColumn[] {
                colBH,
                colMC,colDisplay});

private void setGridColumn(DevExpress.XtraGrid.Columns.GridColumn column
         , string Caption, string FieldName, string Name, int width)
            {
                column.AppearanceHeader.Options.UseTextOptions = true;
                column.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
                column.Caption = Caption;
                column.FieldName = FieldName;
                column.MinWidth = width;
                column.Name = Name;
                column.Visible = true;
                column.VisibleIndex = 0;
                column.Width = width;
            }

#  3、绑定ComboBoxEdit  #

public static void BindRoleGroup(ComboBoxEdit ddlRoleGroup)
            {
                Dictionary<string, string> dic=  MyConst.ROLEGROUP.GetRoleGroup();
    
    
                ddlRoleGroup.Properties.Items.Add(new ComboBoxHelp("", "-请选择-"));
                foreach(var item in dic)
                {
                    ddlRoleGroup.Properties.Items.Add(new ComboBoxHelp(item.Value, item.Key));
                }
    
    
                ddlRoleGroup.Properties.Buttons[0].Kind = DevExpress.XtraEditors.Controls.ButtonPredefines.DropDown;
                ddlRoleGroup.Properties.TextEditStyle = DevExpress.XtraEditors.Controls.TextEditStyles.DisableTextEditor;
    
    
            }

# 4、NavBarConrol动态加载用户控件 #

public mainForm()
            {
                InitializeComponent();
    
                if (LoginUser.GROUPID == "0") // 开发公司
                {
                    navBarMenu.Groups.Clear();
                    this.Text = this.Text + "   开发公司 " + LoginUser.CZYXM;
    
                    MyConst.AdminMenu adminMenu = new MyConst.AdminMenu();
                    DataTable dt = adminMenu.GetAdminMenu();
                    NavBarGroup group;
                    DataRow[] pRows = dt.Select("PGNID='0'");
                    for (int i = 0; i < pRows.Length; i++) {
                        group = new NavBarGroup();
                        group.Caption = pRows[i]["GNMC"].ToString();
                        group.Name = pRows[i]["AssemblyClass"].ToString();
    
                        this.navBarMenu.Groups.AddRange(new NavBarGroup[] {
                        group});
    
                        BindchildMenu(group, dt, pRows[i]["GNID"].ToString());
                    }
                }
                else
                {
                }
            }

void BindchildMenu(NavBarGroup group,DataTable dt, string pGNID)
            {
                DataRow[] cRows = dt.Select("PGNID='" + pGNID + "'");
                NavBarItem barItem;
                for (int i = 0; i < cRows.Length; i++)
                {
    
                    barItem = new NavBarItem();
                    barItem.Caption = cRows[i]["GNMC"].ToString();
                    barItem.Name = cRows[i]["AssemblyClass"].ToString();
    
                    barItem.LinkClicked += new DevExpress.XtraNavBar.NavBarLinkEventHandler(this.lbtn_LinkClicked);
    
                    group.ItemLinks.AddRange(new NavBarItemLink[] {
                        new NavBarItemLink(barItem)});
    
                }
            }

// 加载事件
            private void lbtn_LinkClicked(object sender, DevExpress.XtraNavBar.NavBarLinkEventArgs e)
            {
                NavBarItem navBarItem = sender as NavBarItem;
                UserControl c;
                if (!dic_Controls.TryGetValue(navBarItem.Name, out c))
                {
                    c = Assembly.Load("Hospital").CreateInstance(navBarItem.Name) as UserControl;
                    dic_Controls.Add(navBarItem.Name, c);
                }          
    
                addControl(c);
            }

/// <summary>
            /// 加载控件
            /// </summary>
            /// <param name="control"></param>
            private void addControl(Control control)
            {
                clearControl();
    
                control.Size = this.panelRight.Size;
    
                panelRight.Controls.Clear();
    
                panelRight.Controls.Add(control);
            }

# 5、dxValidationProvider 控件的使用 #

/// <summary>
            /// 验证是否为空
            /// </summary>
            private void ValidatEmptyUser()
            {
                dxValidationProvider1.ValidationMode = ValidationMode.Manual;
                dxValidationProvider1.Validate();
    
                Validate(txtCZYBM, "该字段不能为空！");
                Validate(this.txtLOGID, "该字段不能为空！");
                Validate(this.txtCZYXM, "该字段不能为空！");
                Validate(this.txtROLE, "该字段不能为空！");
                Validate(this.txtPassword, "该字段不能为空！");
                Validate(this.txtConfirmPassword, "该字段不能为空！");
            }
    
            /// <summary>
            /// 验证控件样式
            /// </summary>
            /// <param name="c"></param>
            /// <param name="ErrorText"></param>
            private void Validate(Control c, string ErrorText)
            {
                ConditionValidationRule notEmpty = new ConditionValidationRule();
                notEmpty.ConditionOperator = ConditionOperator.IsNotBlank;
                notEmpty.ErrorText = ErrorText;
                dxValidationProvider1.SetValidationRule(c, notEmpty);
                dxValidationProvider1.SetIconAlignment(c, ErrorIconAlignment.MiddleRight);
            }

# 6、GridControl 选中行下追加一行  #

var SQL = "SELECT ROWNUM AS XH,BH AS KSBH,MC AS FWKS FROM YHWXQ_V_KS where LB='1'";
    
                grid_dataTable = DAL.HISControl.CreateDALControl().GetDataTable(SQL);
    
                this.gridPB.DataSource = grid_dataTable;

// 新增、追加行
            private void btnXZ_Click(object sender, EventArgs e)
            {
                DataRowView dataRowView = (DataRowView)this.advBandedGridView1.GetFocusedRow();
                
                // 当前序号
                int XH = Int32.Parse(dataRowView["XH"].ToString());
                
                // 当前服务科室
                string FWKS = dataRowView["FWKS"].ToString();
    
                // 当前服务科室编号
                string KSBH = dataRowView["KSBH"].ToString();
    
                // 新增行（序号、服务科室、科室编号）
                DataRow newRow = grid_dataTable.NewRow();
                newRow["XH"] = XH+1;
                newRow["FWKS"] = FWKS;
                newRow["KSBH"] = KSBH;
    
                int max_XH = Int32.Parse(grid_dataTable.Compute("max(XH)","").ToString());
    
                for (int i = max_XH; i > XH; i--)
                {
                    grid_dataTable.DefaultView[i - 1]["XH"] = i + 1;
                }
    
                grid_dataTable.Rows.Add(newRow);
                grid_dataTable.DefaultView.Sort = "XH";
                this.gridPB.DataSource = grid_dataTable.DefaultView;
            }
