动态navBarControl1设置 DXperience学习笔记

进行DXperience进行项目开发的时候 navBarControl1 提供了组分类的功能 相对于微软自带的控件本人认为DXperience有着不可超越的优势，在平常学习的过程中，碰到了一些问题 如何对navBarGroup1进行有选择的显示即对于每个登录的用户进行权限分配，今天把学习的经验写出来，希望能给DXperience爱好的初学者一点启发 数据库读取到 dataset后进行编写如下代码

以下是代码片段：
if (ds.Tables[0].Rows.Count > 0) { for (int i = 0; i < ds.Tables[0].Rows.Count; i++) { string id = ds.Tables[0].Rows[i]["id"].ToString(); //该用户可管理的id号 if (User.Power.IndexOf(id) == -1) continue; string mid = ds.Tables[0].Rows[i]["mid"].ToString(); //隶属的管理类型 string name = ds.Tables[0].Rows[i]["PowerName"].ToString(); //管理名称 int cls = int.Parse(ds.Tables[0].Rows[i]["type"].ToString());//图片号码 switch (mid) { case "1": AddGroup(navBarGroup1, name, "n" + id, cls);//AddGroup函数用于在navBarGroup1控件中写入新项 break; case "2": AddGroup(navBarGroup2, name, "n" + id, cls); break; case "3": AddGroup(navBarGroup3, name, "n" + id, cls); break; case "4": AddGroup(navBarGroup4, name, "n" + id, cls); break; case "5": AddGroup(navBarGroup5, name, "n" + id, cls); break; }

} }

以下是AddGroup 函数

以下是代码片段： /// /// 参数传递 添加控件 /// /// /// /// /// private void AddGroup(DevExpress.XtraNavBar.NavBarGroup nbg,string name,string id,int cls ) { try { DevExpress.XtraNavBar.NavBarItem navBarItem1 = new DevExpress.XtraNavBar.NavBarItem(); navBarItem1.Caption = name; navBarItem1.Name = id; navBarItem1.SmallImageIndex = cls; navBarItem1.LinkClicked += new DevExpress.XtraNavBar.NavBarLinkEventHandler(navBarItem1_LinkClicked); //新增项的 点击事件 触发 nbg.ItemLinks.AddRange(new DevExpress.XtraNavBar.NavBarItemLink[] { new DevExpress.XtraNavBar.NavBarItemLink(navBarItem1) }); } catch (Exception ex) { MessageBox.Show(ex.Message); } }

以下是点击事件代码

以下是代码片段：
/// /// 左侧栏点击事件 /// /// /// private void navBarItem1_LinkClicked(object sender, DevExpress.XtraNavBar.NavBarLinkEventArgs e) { try { string pagename = e.Link.Item.Name; //获取左侧栏的name值 string caption = e.Link.Caption; //获取名字 switch (pagename) { case " ": //执行代码 break; }

} catch (Exception ex) { MessageBox.Show(ex.Message); } }

 

Devexpress 之 NavBar 添加/删除

--添加新的ItemLink到 Active Group

int i = 0;

private void button1_Click(object sender, System.EventArgs e) { DevExpress.XtraNavBar.NavBarItem item = navBarControl1.Items.Add(); item.LargeImageIndex = item.SmallImageIndex = imageComboBoxEdit1.SelectedIndex; item.Caption = "Item " + (i++).ToString(); navBarControl1.ActiveGroup.ItemLinks.Add(item); ExistSelectedItemLink(); }

--删除当前所选ItemLink

private void button2_Click(object sender, System.EventArgs e) { if(navBarControl1.ActiveGroup.SelectedLink != null) navBarControl1.ActiveGroup.SelectedLink.Item.Dispose(); ExistSelectedItemLink(); }

 

--改变样式

private void listBox1_SelectedIndexChanged(object sender, System.EventArgs e) { navBarControl1.View = listBox1.SelectedItem as DevExpress.XtraNavBar.ViewInfo.BaseViewInfoRegistrator; navBarControl1.ResetStyles(); }
