通過RadGridView，我怎樣才能顯示詳細信息？

Question

我在RadGridView中創建了一個層次關係。但是這種關係不起作用。我無法顯示詳細信息。我做錯了什麼？

如果我自動生成的所有關係工作正常。但我只需要一張桌子的一個字段作爲詳細信息。進一步：我使用VS2013 Prof.，WinForms作爲UI和LINQ to SQL作爲數據源。

的源代碼是：

private void OpenConfigurations() 
    { 
      bsConfigurations.DataSource = Db.Configurations.Where(c => c.Active == true && c.CompanyId == CurrentCompany.CompanyId).Select(c => c).OrderBy(c => c.Name); 
      bsConfigurationContracts.DataSource = Db.ConfigurationContracts.Where(c => c.Contract.InsurranceId == CurrentCompany.CompanyId).Select(c => 
     c).OrderBy(c => c.Contract.Name); 

      GridViewRelation gvrConfigurations = new GridViewRelation(); 
      gvrConfigurations.ChildColumnNames.Add("ConfigurationId"); 
      gvrConfigurations.ChildTemplate = this.gridViewTemplate1; 
      gvrConfigurations.ParentColumnNames.Add("ConfigurationId"); 
      gvrConfigurations.ParentTemplate = this.gvConfiguration.MasterTemplate; 
      gvConfiguration.Relations.Add(gvrConfigurations); 
} 

在設計師

this.gridViewTemplate1.AllowAddNewRow = false; 
gridViewTextBoxColumn1.EnableExpressionEditor = false; 
gridViewTextBoxColumn1.FieldName = "Contract.Name"; 
gridViewTextBoxColumn1.HeaderText = "Name"; 
gridViewTextBoxColumn1.Name = "colName"; 
gridViewTextBoxColumn1.Width = 250; 
gridViewTextBoxColumn2.EnableExpressionEditor = false; 
gridViewTextBoxColumn2.FieldName = "ConfigurationId"; 
gridViewTextBoxColumn2.HeaderText = "ConfigurationId"; 
gridViewTextBoxColumn2.IsVisible = false; 
gridViewTextBoxColumn2.Name = "colConfigurationId"; 

this.gridViewTemplate1.Columns.AddRange(new Telerik.WinControls.UI.GridViewDataColumn[] { gridViewTextBoxColumn1, gridViewTextBoxColumn2 }); 
this.gridViewTemplate1.DataSource = this.bsConfigurationContracts; 
// 
// gvConfiguration 
// 
this.gvConfiguration.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(233)))), ((int)(((byte)(240)))), ((int)(((byte)(249))))); 
this.gvConfiguration.Cursor = System.Windows.Forms.Cursors.Default; 
this.gvConfiguration.Dock = System.Windows.Forms.DockStyle.Fill; 
this.gvConfiguration.Font = new System.Drawing.Font("Segoe UI", 8.25F); 
this.gvConfiguration.ForeColor = System.Drawing.Color.Black; 
this.gvConfiguration.ImeMode = System.Windows.Forms.ImeMode.NoControl; 
this.gvConfiguration.Location = new System.Drawing.Point(0, 30); 
// 
// 
// 
this.gvConfiguration.MasterTemplate.AllowAddNewRow = false; 
this.gvConfiguration.MasterTemplate.AutoGenerateColumns = false; 
gridViewTextBoxColumn3.EnableExpressionEditor = false; 
gridViewTextBoxColumn3.FieldName = "Name"; 
gridViewTextBoxColumn3.HeaderText = "Name"; 
gridViewTextBoxColumn3.Name = "colName"; 
gridViewTextBoxColumn3.SortOrder = Telerik.WinControls.UI.RadSortOrder.Ascending; 
gridViewTextBoxColumn3.Width = 250; 
gridViewTextBoxColumn4.EnableExpressionEditor = false; 
gridViewTextBoxColumn4.FieldName = "ConfigurationId"; 
gridViewTextBoxColumn4.HeaderText = "ConfigurationId"; 
gridViewTextBoxColumn4.IsVisible = false; 
gridViewTextBoxColumn4.Name = "colConfigurationId"; 
this.gvConfiguration.MasterTemplate.Columns.AddRange(new Telerik.WinControls.UI.GridViewDataColumn[] { gridViewTextBoxColumn3, gridViewTextBoxColumn4 }); 
this.gvConfiguration.MasterTemplate.DataSource = this.bsConfigurations; 
sortDescriptor1.PropertyName = "colName"; 
this.gvConfiguration.MasterTemplate.SortDescriptors.AddRange(new Telerik.WinControls.Data.SortDescriptor[] { sortDescriptor1 }); 
this.gvConfiguration.MasterTemplate.Templates.AddRange(new Telerik.WinControls.UI.GridViewTemplate[] { this.gridViewTemplate1 }); 
this.gvConfiguration.Name = "gvConfiguration"; 
this.gvConfiguration.RightToLeft = System.Windows.Forms.RightToLeft.No; 
this.gvConfiguration.ShowGroupPanel = false; 
this.gvConfiguration.Size = new System.Drawing.Size(1098, 72); 
this.gvConfiguration.TabIndex = 4; 
this.gvConfiguration.Text = "radGridView1"; 
this.gvConfiguration.CellDoubleClick += new Telerik.WinControls.UI.GridViewCellEventHandler(this.gvConfiguration_CellDoubleClick);

的解決方案是，你必須在字段名稱代替添加列名的關係。

因此，這是正確的代碼：

GridViewRelation gvrConfigurations = new GridViewRelation(); 
      gvrConfigurations.ChildColumnNames.Add("colConfigurationId"); 
      gvrConfigurations.ChildTemplate = this.gridViewTemplate1; 
      gvrConfigurations.ParentColumnNames.Add("colConfigurationId"); 
      gvrConfigurations.ParentTemplate = this.gvConfiguration.MasterTemplate; 
      gvConfiguration.Relations.Add(gvrConfigurations);
