1.tree呈现树表结构展示

UltraTree的数据源是Object类型的，，今天我们使用DataSet类型作为其数据源，构造树表结构展示。

step1：构造数据 private DataSet GetTestData(){DataSet dataSet = new DataSet();DataTable dataTableSeries = new DataTable("BusinessProcess");dataTableSeries.Columns.Add("业务过程", typeof(string));dataTableSeries.Columns.Add("UsedPT", typeof(string));dataTableSeries.Columns.Add("GeneratePT", typeof(string));dataTableSeries.Rows.Add(new object[] { "业务过程", "T", "T" });DataTable dataTableSpinoffs = new DataTable("Spinoffs");dataTableSpinoffs.Columns.Add("ParentRecord", typeof(string));dataTableSpinoffs.Columns.Add("业务过程", typeof(string));dataTableSpinoffs.Columns.Add("UsedPT", typeof(string));dataTableSpinoffs.Columns.Add("GeneratePT", typeof(string));dataTableSpinoffs.Rows.Add(new object[] { "业务过程", "规划计划A", "F", "T" });dataTableSpinoffs.Rows.Add(new object[] { "业务过程", "规划计划B", "F", "F" });dataTableSpinoffs.Rows.Add(new object[] { "业务过程", "规划计划C", "T", "F" });dataTableSpinoffs.Rows.Add(new object[] { "规划计划A", "勘探规划a", "F", "F" });dataTableSpinoffs.Rows.Add(new object[] { "规划计划A", "勘探计划a", "T", "F" });dataTableSpinoffs.Rows.Add(new object[] { "规划计划B", "勘探规划b", "F", "T" });dataTableSpinoffs.Rows.Add(new object[] { "规划计划B", "勘探计划b", "F", "F" });dataTableSpinoffs.Rows.Add(new object[] { "规划计划C", "勘探规划c", "T", "F" });dataTableSpinoffs.Rows.Add(new object[] { "勘探规划a", "中长期油气勘探规划", "F", "F" });dataTableSpinoffs.Rows.Add(new object[] { "勘探规划a", "五年期油气勘探滚动规划", "T", "T" });dataTableSpinoffs.Rows.Add(new object[] { "勘探计划b", "年度勘探计划", "T", "T" });dataTableSpinoffs.Rows.Add(new object[] { "勘探计划b", "年度勘探部署", "T", "F" });dataTableSpinoffs.Rows.Add(new object[] { "勘探计划b", "年度部署调整", "F", "T" });dataSet.Tables.Add(dataTableSeries);dataSet.Tables.Add(dataTableSpinoffs);dataSet.Relations.Add("dataTableSeries", dataTableSeries.Columns["业务过程"], dataTableSpinoffs.Columns["ParentRecord"], false);dataSet.Relations.Add("SpinoffToSpinoff", dataTableSpinoffs.Columns["业务过程"], dataTableSpinoffs.Columns["ParentRecord"], false);return dataSet;}step2：绑定数据源

this.ultraTree1.ViewStyle = ViewStyle.OutlookExpress;this.ultraTree1.DataSource = GetTestData();this.ultraTree1.DataMember = "BusinessProcess";step3：设置列宽（或使列自适应）

//实现列的自适应（好像不怎么起作用）// this.ultraTree1.ColumnSettings.AutoFitColumns = AutoFitColumns.ResizeAllColumns;//设置列宽（这个比较好用）this.ultraTree1.ColumnSettings.ColumnSets[0].Columns[0].LayoutInfo.PreferredLabelSize = new Size(250, 0);

注意：

There is no way to auto-size columns exceptwhen using theOutlookExpress ViewStyle:

this.ultraTree1.ColumnSettings.AutoFitColumns = AutoFitColumns.ResizeAllColumns;

其他的样式需要手动设置列的size

step4：隐藏某些列

UltraTree1.ColumnSettings.ColumnSets(X).Columns(Y).Visible = FalseWhere X is the columnset name / index and Y is the column name / index

懂得倾听别人的忠告。
