If the modal dialog shows outdated calendar event data (especially in IE) it might be necessary to force a reload from the server.

There are two ways to do it:

• Disable caching in the calendar event details page (Edit.aspx or New.aspx)
• Add a random string to the calendar event details page URL in showUrl()

1. Disable caching in the modal dialog page

Add the following code to page that handles the modal dialog content (usually Edit.aspx):

private void Page_Load(object sender, System.EventArgs e)
{
  // ...
  Response.Cache.SetNoServerCaching();
  Response.Cache.SetNoStore();
  // ...
}

2. Add a random string to the modal dialog page URL

Modify the dialog source URL by adding a random dummy parameter:

  function eventClick(e) {
    var modal = dialog();
    modal.showUrl("Edit.aspx?id=" + e.value() + "&dummy=" + new Date().getTime());
  }

  function dialog() {
    var modal = new DayPilot.Modal();
    modal.top = 60;
    modal.width = 300;
    modal.opacity = 70;
    modal.border = "10px solid #d0d0d0";
    modal.closed = function() { 
      if(this.result == "OK") { 
        dps1.commandCallBack('refresh'); 
      }
      dps1.clearSelection();
    };
	
    modal.height = 250;
    modal.zIndex = 100;
    return modal;
  }
