用户控制按钮在一页上工作正常，但在另一页上工作不正常

Question

我有一个radgrid用户控件（rgTask），该用户控件具有另一个用户控件（ContractTaskInput）作为编辑表单。 rgTask分两页（ContractDetail和LeasingContractDetail）。

我已将这些事件公开，因此页面可以不同地使用它们

 public partial class ContractTaskGrid : System.Web.UI.UserControl
   {
    public event EventHandler<GridNeedDataSourceEventArgs> NeedDataSource;
    public event EventHandler<GridCommandEventArgs> UpdateCommand;
    public event EventHandler<GridCommandEventArgs> DeleteCommand;
    public event EventHandler<GridCommandEventArgs> InsertCommand;
    public event EventHandler<GridItemEventArgs> ItemDataBound;

    void OnUpdateCommand(object sender, GridCommandEventArgs e)
    {
        if (UpdateCommand != null)
        {
            UpdateCommand(sender, e);
        }
    }
    void OnDeleteCommand(object sender, GridCommandEventArgs e)
    {
        if (DeleteCommand != null)
        {
            DeleteCommand(sender, e);
        }
    }
    void OnInsertCommand(object sender, GridCommandEventArgs e)
    {
        System.Diagnostics.Debug.WriteLine("InsertCommandnull?");

        if (InsertCommand != null)
        {
            System.Diagnostics.Debug.WriteLine("InsertCommandnotnull");

            InsertCommand(sender, e);
        }
    }
    void OnNeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        if (NeedDataSource != null)
        {
            NeedDataSource(sender, e);
        }
    }
    void OnItemDataBound(object sender, GridItemEventArgs e)
    {
        if (ItemDataBound != null)
        {
            ItemDataBound(sender, e);
        }
    }


    public RadGrid Grid
    {
        get { return rgTask; }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        System.Diagnostics.Debug.WriteLine("Load Grid");
    }

    protected void rgTask_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
    {
        OnNeedDataSource(sender, e);
    }

    protected void rgTask_UpdateCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
    {
        OnUpdateCommand(sender, e);
    }

    protected void rgTask_DeleteCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
    {
        OnDeleteCommand(sender, e);
    }

    protected void rgTask_InsertCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
    {
        System.Diagnostics.Debug.WriteLine("rgTask_InsertCommand run assigned");
       OnInsertCommand(sender, e);
    }


    protected void rgTask_ItemDataBound(object sender, GridItemEventArgs e)
    {
        OnItemDataBound(sender, e);
    }
}

所有事件在ContractDetail页上都可以正常工作，但是只有InsertCommand和UpdateCommand在LeasingContractDetail页上无法正常工作。

下面是ContractTaskInput控件

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ContractTaskInput.ascx.cs" Inherits="EBT.Web.Control.BillingModule.ContractTaskInput" %>
<div class="divStyle">
    <table>

        <tr>
            <td>
                Assigned To:
            </td>
            <td>
                <telerik:RadComboBox ID="rcbAssignedTo" runat="server" Filter="Contains"
                        Width="200px" DropDownAutoWidth="Enabled" OnDataBinding="rcbAssignedTo_DataBinding"
                        AutoPostBack="false" CausesValidation="false">
                    </telerik:RadComboBox>
            </td>
        </tr>

        <tr>
            <td>
                Assigned Task:

             <td><telerik:RadTextBox ID="txtAssignedTask" runat="server" Width="500px"

            <td>
                 <asp:RequiredFieldValidator ID="rfAssignedTask" runat="server"
                        ErrorMessage="* Required" ValidationGroup="ActivityValidation"
                        ControlToValidate="txtAssignedTask"
                        Display="Dynamic" ForeColor="Red" />
             </td>
        </tr>       
        <tr>
            <td>
                Status:

            <td>

                        Width="200px" DropDownAutoWidth="Enabled" OnDataBinding="rcbStatus_DataBinding"
                        AutoPostBack="false" CausesValidation="false">
                    </telerik:RadComboBox>
            </td>
        </tr>
        <tr>
            <td colspan="2">
                <asp:ValidationSummary ID="ValidationSummary1" runat="server"
                    HeaderText='Please correct the following error before proceed:'
                    ForeColor="Red" />
            </td>
        </tr>
        <tr>
            <td class="alignTop">
                <asp:Button ID="btnUpdateTask" runat="server" ValidationGroup="ActivityValidation"
                    Text='<%# (Container is GridEditFormInsertItem) ? "Insert" : "Update" %>'
                    CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>'></asp:Button>
                &nbsp;
                <asp:Button ID="btnCancel" Text="Cancel" runat="server" CausesValidation="False" CommandName="Cancel"></asp:Button>
                &nbsp;&nbsp;

                <asp:Label ID="lblMsg" runat="server" EnableViewState="false" ForeColor="red"></asp:Label>
            </td>
            <asp:HiddenField ID="hfContractId" runat="server" /> 
            <asp:HiddenField ID="hfTaskId" runat="server" />
            <asp:HiddenField ID="hfCurrentStatus" runat="server" /> 
        </tr>
    </table>
</div>

我认为问题出在btnUpdate上，因为删除功能在两个页面上都可以正常工作。我对事件处理不太熟悉，因此非常感谢您提供有关此问题的任何帮助。
