如何通过单击按钮将参数传递给OpenRadWindow方法

Question

The Calling aspx page contains the following:
page element logic:


   <tr
    > class="PROPERTYVALUEPAIR2">
    >  <td class="PROPERTYLABEL2">
    >                                 <asp:Label ID="labelDataSourceName" runat="server" >AssociatedControlID="textboxDataSourceName" Text="Data
    > Source Name" />
    >          </td>
    >    <td class="PROPERTYVALUE2">
    >                                 <MyControls:TNRadTextBox ID="textboxDataSourceName" runat="server" MaxLength="300" Width="520"
    > EnableEmbeddedSkins="false" Skin="Tienet" />
    >                                 <asp:CustomValidator ID="validate_textboxDataSourceName" runat="server"
    > ControlToValidate="textboxDataSourceName" CssClass="BAD"
    > Display="Dynamic"
    >                                     OnServerValidate="validate_textboxDataSourceName_ServerValidate"
    > ValidateEmptyText="true" />
    >                               
    >                                                              </td>
    >                         </tr> 

然后按钮逻辑如下：

<asp:Button ID="btnConfirmMySave" runat="server" 
                                      NavigateUrl="aaconfirmsettings.aspx" 
                                 OnClientClick="return openRadWindow('aaconfirmsettings.aspx','radWindowaaConfirmSettings')" 
                                    Text="Accept" Type="Accept" OnClientShow="clientShow()"/>

脚本逻辑：

  <MyControls:TNRadWindowManager ID="radWindowManager" runat="server" Behaviors="Resize, Close, Move"
            Modal="True" KeepInScreenBounds="True" VisibleStatusbar="False" Skin="MySkins" EnableEmbeddedSkins="False"
            OnClientClose="closingRadWindow" ShowContentDuringLoad="False" ReloadOnShow="True"
            AutoSize="True" DestroyOnClose="False" InitialBehaviors="None">
            <Shortcuts>
                <telerik:WindowShortcut CommandName="CloseAll" Shortcut="Esc"></telerik:WindowShortcut>
            </Shortcuts>
            <Windows>
                <tienetControls:TNRadWindow ID="radWindowaaConfirmSettings" runat="server" MinHeight="320" MinWidth="700" />
            </Windows>
        </tienetControls:TNRadWindowManager>


    <telerik:RadCodeBlock ID="radCodeBlock" runat="server">
            <script type="text/javascript">
               function openRadWindow(url, windowId) {
                    var oManager = GetRadWindowManager();

                    oWnd = radopen(url, windowId);
                    oWnd.center();
                    return false;
                }


                function clientShow(sender, eventArgs) {
                var txtInput = document.getElementById("textboxDataSourceName");
                sender.argument = txtInput.value;
            }

                function closingRadWindow(oWnd, args) {
                    var oArgs = args.get_argument();
                    if (oArgs) {
                        if (oArgs.redirectUrl) {
                            document.location = oArgs.redirectUrl;
                        } else if (oArgs.windowId && oArgs.url) {
                            openRadWindow(oArgs.url, oArgs.windowId);
                        } else if (oArgs.refresh == true) {
                            document.location = document.location;
                        }
                    }
                }

            </script>
        </telerik:RadCodeBlock>

调用aaconfirmsettings.aspx页面，在这里我需要使用传递的txtInput.value参数来处理和显示数据。

我能够在不传递参数的情况下加载页面，但无法将参数传递给aaconfirmsettings.aspx rad窗口。
