(DevExpress2011控件教程)ASPXTreeList 范例2: ASPxTreeList杂项设置

1、交替的节点颜色设置

属性—>Styles->AlternationgNode->BackColor

 

2、网格线与树线条

属性->Settings->GridLines

属性->Settings->ShowTreeLines

 

3、条件格式

 ASPxTreeList允许你对个别数据Cell或者是完整节点设置个性化样式设计 ,你可以使用HtmlDataCellPrepared or HtmlRowPrepared 方法去设置你需要的设置

例如上例中添加

protected void treeList_HtmlDataCellPrepared(object sender, DevExpress.Web.ASPxTreeList.TreeListHtmlDataCellEventArgs e)

        {

            if (Object.Equals(e.GetValue("dptname"), "部门1A"))

                e.Cell.Font.Bold = true;

        }

4、节点

多行选择

1.     SettingsSelection.Enabled 属性设置为True

2.     SettingsSelection.AllowSelectAll 属性设置为 true

3.     SettingsSelection.Recursive 反选属性设置为true

5、数据导出

ASPxTreeList 很容易的使用ASPxTreeListExporter组件导出数据

treeListExporter.WriteRtfToResponse();

treeListExporter.WriteXlsxToResponse();

treeListExporter.WriteXlsToResponse();

treeListExporter.WritePdfToResponse();

 

6、数据分页

 SettingsPager.Mode 属性设置为 ShowPager.

7、数据统计

AspxTreeList 能使你进行单列或一组节点的计算统计,显示的结果在页脚的单元。AspxTreeList提供5个嵌入聚集函数 count ,max,min等等)

步骤一 把Settings.ShowFooter属性设置为 true.

步骤二 组页脚显示 Settings.ShowGroupFooter属性设置为 true.

 <Settings ShowGroupFooter="True" ShowFooter="True" GridLines="Both" />

  <Summary>
            
<dx:TreeListSummaryItem FieldName="dptname" ShowInColumn=" dptname " SummaryType="Count" />
       
</Summary>

 如果在代码里写。。。

private void TreeDataBind()

            {

               string Sql="select * from com_Dpt";

               DataSet ds= db.ExecuteDataSet(System.Data.CommandType.Text, Sql);

               treeList.DataSource =ds.Tables[0];

               treeList.KeyFieldName = "dptid";

               treeList.ParentFieldName = "dptfatherid";

               TreeListSummaryItem a = new TreeListSummaryItem();

               a.FieldName = "dptName";

               a.ShowInColumn = "dptName";

               a.SummaryType = DevExpress.Data.SummaryItemType.Count ;

                treeList.Summary.Add(a);

                treeList.DataBind();

              

            }
