我如何在 telerik radgridview 的顶层显示多个独立模板

Question

 hello:
  i want add multiple template to radgridview and show templates in tabbed style ,
my templates is independent and no relation to each other, 
when i add templates to masterTemplate and set datasource of my templates,
datagrid is show empty grid and templates is not visible.
some tried code :  
Add Template Section:

                            GridViewTemplate gvt = new GridViewTemplate();
                        gvt.AllowDeleteRow = false;
                        gvt.AllowEditRow = false;
                        gvt.ShowTotals = true;
                        gvt.Caption = SubCaption[i];
                        radResult.MasterTemplate.Templates.Add(gvt);
                        radResult.Refresh();

设置Indexnumber为模板索引的数据源部分：

            radResult.MasterTemplate.Templates[IndexNumber].DataSource = dtl;
            radResult.MasterTemplate.Templates[IndexNumber].Refresh();
            radResult.Refresh();

我想要的视图是： RadGridView target view

我该怎么做？
提前致谢

RadGridView 仅通过 MasterGridViewTemplate 提供一个主级别。您可以根据需要将任意数量的子 GridViewTemplates 添加到主级别。此处提供更多信息：https://docs.telerik.com/devtools/winforms/controls/gridview/hierarchical-grid/hierarchy-of-one-to-many-relations

但是，这需要 MasterTemplate 和每个子 GridViewTemplate 之间的关系。

为了从父级别的 RadGridView 中的选项卡式视图的屏幕截图实现您的设计，我可以建议以下方法：

使用单个 RadGridView 实例并使用 load on demand 设置层次结构。为此，有必要为主级别添加一个虚拟行并保持扩展。以下代码片段显示了如何实现它：

     private void RadForm1_Load(object sender, EventArgs e)
 {
     // TODO: This line of code loads data into the 'nwindDataSet.Products' table. You can move, or remove it, as needed.
     this.productsTableAdapter.Fill(this.nwindDataSet.Products);
     // TODO: This line of code loads data into the 'nwindDataSet.Orders' table. You can move, or remove it, as needed.
     this.ordersTableAdapter.Fill(this.nwindDataSet.Orders);
     // TODO: This line of code loads data into the 'nwindDataSet.Categories' table. You can move, or remove it, as needed.
     this.categoriesTableAdapter.Fill(this.nwindDataSet.Categories);

     this.radGridView1.MasterTemplate.Columns.Add("MasterLevel");
     this.radGridView1.MasterTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

     this.radGridView1.MasterTemplate.AllowAddNewRow = false;
     this.radGridView1.ShowColumnHeaders = false;
     this.radGridView1.ShowGroupPanel = false;

     GridViewTemplate childTemplateCategories = new GridViewTemplate();
     childTemplateCategories.Caption = "Categories";
     foreach (DataColumn col in this.nwindDataSet.Categories.Columns)
     {
         childTemplateCategories.Columns.Add(col.ColumnName);
     }
     childTemplateCategories.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
     this.radGridView1.Templates.Add(childTemplateCategories);
     childTemplateCategories.HierarchyDataProvider = new GridViewEventDataProvider(childTemplateCategories);

     GridViewTemplate childTemplateProducts = new GridViewTemplate();
     childTemplateProducts.Caption = "Products";
     foreach (DataColumn col in this.nwindDataSet.Products.Columns)
     {
         childTemplateProducts.Columns.Add(col.ColumnName);
     }
     childTemplateProducts.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
     this.radGridView1.Templates.Add(childTemplateProducts);
     childTemplateProducts.HierarchyDataProvider = new GridViewEventDataProvider(childTemplateProducts);

     GridViewTemplate childTemplateOrders = new GridViewTemplate();
     childTemplateOrders.Caption = "Orders";
     foreach (DataColumn col in this.nwindDataSet.Orders.Columns)
     {
         childTemplateOrders.Columns.Add(col.ColumnName);
     }
     childTemplateOrders.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
     this.radGridView1.Templates.Add(childTemplateOrders);
     childTemplateOrders.HierarchyDataProvider = new GridViewEventDataProvider(childTemplateOrders);

     this.radGridView1.RowSourceNeeded += new GridViewRowSourceNeededEventHandler(radGridView1_RowSourceNeeded);

     this.radGridView1.Rows.Add("Master");
     this.radGridView1.Rows[0].IsExpanded = true; 
 }

 private void radGridView1_RowSourceNeeded(object sender, GridViewRowSourceNeededEventArgs e)
 {
     if (e.Template.Caption == "Categories")
     {
         foreach (DataRow row in this.nwindDataSet.Categories.Rows)
         {
             GridViewRowInfo r = e.Template.Rows.NewRow();
             foreach (GridViewCellInfo cell in r.Cells)
             {
                 cell.Value = row[cell.ColumnInfo.Name];
             }
             e.SourceCollection.Add(r);
         }
     }
     else if (e.Template.Caption == "Products")
     {
         foreach (DataRow row in this.nwindDataSet.Products.Rows)
         {
             GridViewRowInfo r = e.Template.Rows.NewRow();
             foreach (GridViewCellInfo cell in r.Cells)
             {
                 cell.Value = row[cell.ColumnInfo.Name];
             }
             e.SourceCollection.Add(r);
         }
     }
     else if (e.Template.Caption == "Orders")
     {
         foreach (DataRow row in this.nwindDataSet.Orders.Rows)
         {
             GridViewRowInfo r = e.Template.Rows.NewRow();
             foreach (GridViewCellInfo cell in r.Cells)
             {
                 cell.Value = row[cell.ColumnInfo.Name];
             }
             e.SourceCollection.Add(r);
         }
     }
 }

使用 RadDock or a RadPageView 并根据需要添加任意数量的选项卡 documents/pages。然后，在每个 tab/page 上添加一个单独的 RadGridView 控件并用相关数据填充它。

请随意使用最适合您要求的方法。
