如何以编程方式在Telerik中构建CommandItemTemplate？

我有一个关于Telerik的问题。我有一个RadGrid里面的MasterTableView我有一个DetailTables标签（所以我有一个层次结构），我也有我的MasterTableView标签的CommandItemTemplate标签。当它从标记运行时，一切都很好，但我试图从后面的代码编程构建。不幸的是我没有成功。一切正常，除了我的CommandItemTemplate无处。如何以编程方式在Telerik中构建CommandItemTemplate？

我的方法：我有这个CommandItemTemplate我MasterTableView内：

 <CommandItemTemplate> 
      <div class="cmdItem"> 
       <asp:LinkButton ID="btnAddShift" runat="server" CommandName="AddShift" OnClientClick="return fireCommand('AddShift', '');"> 
        <img alt="" src="../../Images/Icons/AddRecord.png" />Add Shift</asp:LinkButton>&#160;&#160;&#160; 
       <asp:LinkButton ID="btnExportCSV" runat="server" CommandName="Export CSV" OnClientClick="return exportGrid('CSV');"><img alt="" src="../../Images/Icons/ExportCSV.png" />Export to CSV</asp:LinkButton>&#160;&#160;&#160; 
       <asp:LinkButton ID="btnManageShiftColumns" runat="server" CommandName="ManageShiftColumns" OnClientClick="return fireCommand('ManageShiftColumns', '');"> 
        <img alt="" src="../../Images/Icons/Columns.png" />Manage Shift Columns</asp:LinkButton>&#160;&#160;&#160; 
       <asp:LinkButton ID="btnManageJobColumns" runat="server" CommandName="ManageJobColumns" OnClientClick="return fireCommand('ManageJobColumns', '');"> 
        <img alt="" src="../../Images/Icons/Columns.png" />Manage Job Columns</asp:LinkButton>&#160;&#160;&#160; 
       <%--<asp:LinkButton ID="btnDetailedExportCSV" runat="server" CommandName="Export CSV Detailed" 
        OnClientClick="return exportGrid('CSVDetailed');"><img alt="" src="../../Images/Icons/ExportCSV.png" />Detailed Export to CSV</asp:LinkButton>&#160;&#160;&#160; 
       <asp:LinkButton ID="btnExportPDF" runat="server" CommandName="Export PDF" OnClientClick="return exportGrid('PDF');"><img alt="" src="../../Images/Icons/ExportPDF.png" />Export to PDF</asp:LinkButton>&#160;&#160;&#160;--%> 
      </div> 
     </CommandItemTemplate>

我已经摆脱了那个标记，我已经创建了一个辅助类：

Private Class RadGridHeaderTemplate 
    Implements ITemplate 


    Public Sub New() 
    End Sub 

    Public Sub InstantiateIn(ByVal container As System.Web.UI.Control) Implements System.Web.UI.ITemplate.InstantiateIn 
     Dim div As HtmlGenericControl = New HtmlGenericControl("div") 
     div.Attributes.Add("class", "cmdItem") 

     Dim addShiftButton As LinkButton = New LinkButton With {.ID = "btnAddShift", .CommandName = "AddShift", .OnClientClick = "return fireCommand('AddShift', '');"} 
     Dim addShiftButtonImage As HtmlGenericControl = New HtmlGenericControl("img") 
     addShiftButtonImage.Attributes.Add("alt", "") 
     addShiftButtonImage.Attributes.Add("src", "../../Images/Icons/AddRecord.png") 
     addShiftButton.Controls.Add(addShiftButtonImage) 
     addShiftButton.Text = "Add Shift" 

     Dim exportCSVButton As LinkButton = New LinkButton With {.ID = "btnExportCSV", .CommandName = "Export CSV", .OnClientClick = "return exportGrid('CSV');"} 
     Dim exportCSVButtonImage As HtmlGenericControl = New HtmlGenericControl("img") 
     exportCSVButtonImage.Attributes.Add("alt", "") 
     exportCSVButtonImage.Attributes.Add("src", "../../Images/Icons/ExportCSV.png") 
     exportCSVButton.Controls.Add(exportCSVButtonImage) 
     exportCSVButton.Text = "Export to CSV" 

     Dim manageShiftColumnButton As LinkButton = New LinkButton With {.ID = "btnManageShiftColumns", .CommandName = "ManageShiftColumns", .OnClientClick = "return fireCommand('ManageShiftColumns', '');"} 
     Dim manageShiftColumnButtonImage As HtmlGenericControl = New HtmlGenericControl("img") 
     manageShiftColumnButtonImage.Attributes.Add("alt", "") 
     manageShiftColumnButtonImage.Attributes.Add("src", "../../Images/Icons/Columns.png") 
     manageShiftColumnButton.Controls.Add(manageShiftColumnButtonImage) 
     manageShiftColumnButton.Text = "Manage Shift Columns" 

     Dim manageJobColumnButton As LinkButton = New LinkButton With {.ID = "btnManageJobColumns", .CommandName = "ManageJobColumns", .OnClientClick = "return fireCommand('ManageJobColumns', '');"} 
     Dim manageJobColumnButtonImage As HtmlGenericControl = New HtmlGenericControl("img") 
     manageJobColumnButtonImage.Attributes.Add("alt", "") 
     manageJobColumnButtonImage.Attributes.Add("src", "../../Images/Icons/Columns.png") 
     manageJobColumnButton.Controls.Add(manageJobColumnButtonImage) 
     manageJobColumnButton.Text = "Manage Job Columns" 

     div.Controls.Add(addShiftButton) 
     div.Controls.Add(exportCSVButton) 
     div.Controls.Add(manageShiftColumnButton) 
     div.Controls.Add(manageJobColumnButton) 

     container.Controls.Add(div) 
    End Sub 
End Class

我在我的CreateGrid方法中使用这个类来创建我的RadGrid，并将其添加到页面的控件中。我这样使用它：

Protected Sub CreateGrid() 
     RadGrid1 = New RadGrid With {.ID = "RadGrid1", .AutoGenerateColumns = True, .AllowCustomPaging = True, .AllowMultiRowSelection = True} 
'... 
     Dim template As RadGridHeaderTemplate = New RadGridHeaderTemplate() 
     template.InstantiateIn(RadGrid1.MasterTableView) 
'... 
End Sub

不幸的是，这种方法不起作用。我没有任何错误，但我的CommandItemTemplate无处可用，我的LinkButtons不会出现在UI上，它们不是生成的标记的一部分。

任何帮助表示赞赏。

此致敬意，

在我的源代码以下部分失踪：

RadGrid1.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.Top

由于RadGrid1.MasterTableView.CommandItemDisplay初始化我可以看到我的项目命令模板，我可以用我的项目命令模板提供的功能。
