Refreshing the page when a popup is closed in ASPX and C#

I am facing an issue with my code.

Within my asp:Wizard element, I have multiple steps. In one step, when I click on a button, a popup opens using window.open to select a date and time. However, after selecting the datetime in the popup, it is not visible in the parent window until I manually refresh the page by clicking on window.open again. I've tried reloading the parent page when closing the popup using 

window.parent.opener.location.reload
, but this approach resets the active step of my wizard. So, I'm looking for a solution that allows me to partially refresh the page while keeping the current step intact. Below is the relevant code snippet:

My opener:

var childWindow = window.open("../../Utils/CalendarPopup.aspx?DatePred=Stateme‌​ntDateFrom", "", "height=280; width=285;");
childWindow.onunload = function () 
{ // Need to reload here }

My popup:

Session[Request.Params["DatePred"]] = CalendarSelectDate.SelectedDate;
Session["CalendarPopupCanceled"] = 0;
this.ClosePage();

Data loading:

if (Session["StatementDateFrom"] != null)
        {                
            {
                (WizardProcess.FindControl("DtTxtBxStatementDateFrom") as Syncfusion.Web.UI.WebControls.Shared.DateTimeTextBox).IsNullDate = false;
                (WizardProcess.FindControl("DtTxtBxStatementDateFrom") as Syncfusion.Web.UI.WebControls.Shared.DateTimeTextBox).Value = System.Convert.ToDateTime(Session["StatementDateFrom"]);
            }            
            Session["StatementDateFrom"] = null;
        }

Thank you for your assistance.

Answer №1

I'm not sure about the method you used to write your code, but is it necessary to refresh the child window? If you have a control such as a textbox that shows the selected datetime from the childWindow, you can simply update the control's value with the selected datetime. This approach might be simpler than attempting to refresh just the wizard!
