我使用ASP.NET控制器来显示用户详细信息。 RadWindow开放时&我试图用关闭按钮关闭。但问题是,在页面加载和回发后,它会一次又一次地打开。我在页面上有多个选项:新建,保存,打印等搜索。

<telerik:RadWindow ID="rwReport" runat="server" Behaviors="Close" KeepInScreenBounds="true"
                        AutoSize="true" VisibleOnPageLoad="false" Modal="true" Title="Report ACMI Advance Payment"
                        DestroyOnClose="true">
                        <ContentTemplate>
                            <ucRPV:ReportViewer id="ucReportViewer" runat="server" />
                        </ContentTemplate>
                    </telerik:RadWindow>

cs file code
 private void Print() 
        {
            try
            {
               // this.sADPs.DisplayReport();
                Hashtable reportParameters = new Hashtable();

                reportParameters.Add("DataSourceName", "dsACMIAdvancePayment");
                reportParameters.Add("reportName", "rptACMIAdvancePayment.rdlc");
                reportParameters.Add("Id", this.hfId.Value.ToString().ConvertTo<long>());

                this.ucReportViewer.clearReport();
                this.ucReportViewer.showReport(reportParameters);
                this.rwReport.VisibleOnPageLoad = true;

                //showReport(reportParameters);

            }
            catch(Exception e) 
            {
                throw e;
            }                      
        }

ASPX代码:

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="AjaxControlToolkit" %>
<%@ Register Src="../Reports/rpvReportViewerPopup.ascx" TagName="ReportViewer" TagPrefix="ucRPV" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<%@ Register Src="../Common/UserControls/ToolBarActions.ascx" TagName="ToolBarActions" TagPrefix="ucTBA" %>
        </td>

您可以尝试以下代码:这可能会有所帮助 -

<telerik:RadScriptBlock runat="server" ID="scriptBlock">

    <script type="text/javascript">
        //<![CDATA[
        function GetRadWindow() {
            var oWindow = null;
            if (window.radWindow) oWindow = window.radWindow;
            else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
            return oWindow;
        }
        function CloseWin() {
            //Get the RadWindow  
            var oWindow = GetRadWindow();
            //Call its Close() method
            if (oWindow) {
                oWindow.Close();
            }
            return false;
        }
 </script>
 </telerik:RadScriptBlock>

在页面上:yourpage.aspx; ...调用onClientClick函数按钮:

<asp:Button ID="btnClose" Text="Close" runat="server" CssClass="button" Enabled="true" OnClientClick="CloseWin();" />

我在重新加载页面时遇到了同样的问题,因为浏览器会重新发送信息并再次打开radwindow。为了避免这种行为,我采用了以下解决方案:

添加隐藏字段以保存客户端代码:

<asp:HiddenField runat="server" ID="_repostcheckcode" />

在代码页中添加以下代码:

protected void Page_Load(object sender, EventArgs e)
{
    CancelUnexpectedRePost();
}

private void CancelUnexpectedRePost()
{
    string clientCode = _repostcheckcode.Value;

    //Get Server Code from session (Or Empty if null)
    string serverCode = Session["_repostcheckcode"] as string  ?? "";

    if (!IsPostBack || clientCode.Equals(serverCode))
    {
        //Codes are equals - The action was initiated by the user
        //Save new code (Can use simple counter instead Guid)
        string code = Guid.NewGuid().ToString();  
        _repostcheckcode.Value = code;
        Session["_repostcheckcode"] = code;
    }
    else
    {
        //Unexpected action - caused by F5 (Refresh) button
        Response.Redirect(Request.Url.AbsoluteUri);
    }
}

不要使用VisibleOnPageLoad属性来显示RadWindow,注册一个将调用其show()方法的脚本。因此,后续回发不会使其自行显示:http://www.telerik.com/help/aspnet-ajax/window-troubleshooting-opening-from-server.html

当然,如Felice建议的那样阻止表格重新提交是另一件可能需要的事情。

将其转换为代码:

而不是:

this.rwReport.VisibleOnPageLoad = true;

使用:

string script = "function f(){$find(\"" + rwReport.ClientID + "\").show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, true);

使用以下代码添加带有 Button 处理程序的 OnClick

    protected void CloseRadWindow(object sender, EventArgs e)
    {
        rwReport.VisibleOnPageLoad = false;
    }
