在工作中經常會碰到需要做行中行,多級行的情況,不熟的情況下,我也只能試著實現.
名稱空間
using DevExpress.XtraEditors.Repository;
using System.Data.SqlClient;
實現程式碼
一下實現的也只是一個demo,大家不要拘泥於資料
實現效果如下:DB db = new DB(); DataSet ds = new System.Data.DataSet(); SqlCommand comm2 = new SqlCommand(sql, db.getSqlConnection()); //db.getSqlConnection() 返回一個sqlConnection 物件 SqlCommand comm3 = new SqlCommand(sql1, db.getSqlConnection()); SqlCommand comm4 = new SqlCommand(sql2, db.getSqlConnection()); SqlDataAdapter da2 = new SqlDataAdapter(comm2); SqlDataAdapter da3 = new SqlDataAdapter(comm3); SqlDataAdapter da4 = new SqlDataAdapter(comm3); da2.Fill(ds,"emp"); da3.Fill(ds,"job"); da4.Fill(ds,"re"); this.treeListLookUpEdit1TreeList.DataSource = ds; DataColumn parentColumn = ds.Tables["emp"].Columns["empNum"]; DataColumn childColumn = ds.Tables["job"].Columns["empNum"]; DataColumn secondChild = ds.Tables["re"].Columns["empNum"]; DataRelation relCustOrder; relCustOrder = new DataRelation("對應工作", parentColumn, childColumn); DataRelation job; job = new DataRelation("部門調整", childColumn, secondChild); ds.Relations.Add(relCustOrder); ds.Relations.Add(job); this.gridControl1.DataSource = ds.Tables["emp"];
