[Solved] Date column in RadGrid within Web User Control not working

[Gavin Russell]

Hello,

I have placed a RadGrid within a "Web user control" (ascx) page.

But when placing an item into edit mode the page generates an error captured by IE (but not the server).

The error comes back as

But I'm uncertain how to begin troubleshooting this - after all, line 108699950 doesn't exist. When I place the control on its own page then the calendar works fine. While on the "user control" page - clicking on the calendar icon has no affect.

Hi,

I've read the forum and it does look like something similar is occuring but I can't see how its solution can be applied?

The article suggests an invalid character is added into a reference by a control and the solution is to remove it using:-

dock.ID = Guid.NewGuid().ToString().Replace('-', 'a');

I tried replacing the lines that look similar, creating something like this

            Dim userControlName As String = e.PageView.ID
            Dim userControl As Control = Page.LoadControl(userControlName)
            userControl.ID = e.PageView.ID.ToString().Replace("-", "a") & "_userControl"
            e.PageView.Controls.Add(userControl)

I would benefit from some additional guidance?

Thanks,

Gavin.

Hi,

I found the line it occurs within.

    $create(Telerik.Web.UI.RadCalendar, {"_DayRenderChangedDays":{},"_FormatInfoArray":[["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"],["Sun","Mon","Tue","Wed","Thu","Fri","Sat"],["January","February","March","April","May","June","July","August","September","October","November","December",],["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec",],"dd MMMM yyyy HH:mm:ss","dd MMMM yyyy","HH:mm:ss","dd MMMM","ddd, dd MMM yyyy HH\':\'mm\':\'ss \'GMT\'","dd/MM/yyyy","HH:mm","yyyy\'-\'MM\'-\'dd\'T\'HH\':\'mm\':\'ss","yyyy\'-\'MM\'-\'dd HH\':\'mm\':\'ss\'Z\'","MMMM yyyy","AM","PM","/",":",1],"_ViewRepeatableDays":{},"_ViewsHash":{infraVB.ascx_userControl_RadGrid2_gdtcSharedCalendar_Top : [[2009,11,1], 1]},"_calendarWeekRule":0,"_culture":"en-GB","_enableViewSelector":false,"_firstDayOfWeek":7,"_postBackCall":"__doPostBack(\u0027infraVB.ascx_userControl$RadGrid2$gdtcSharedCalendar\u0027,\u0027@@\u0027)","clientStateFieldID":"infraVB.ascx_userControl_RadGrid2_gdtcSharedCalendar_ClientState","enabled":true,"monthYearNavigationSettings":["Today","OK","Cancel","Date is out of range.","False","True","300","300"],"skin":"Office2007","specialDaysArray":[],"stylesHash":{DayStyle: ["", ""],CalendarTableStyle: ["", "rcMainTable"],OtherMonthDayStyle: ["", "rcOtherMonth"],TitleStyle: ["", ""],SelectedDayStyle: ["", "rcSelected"],SelectorStyle: ["", ""],DisabledDayStyle: ["", "rcDisabled"],OutOfRangeDayStyle: ["", "rcOutOfRange"],WeekendDayStyle: ["", "rcWeekend"],DayOverStyle: ["", "rcHover"],FastNavigationStyle: ["", "RadCalendarMonthView RadCalendarMonthView_Office2007"],ViewSelectorStyle: ["", "rcViewSel"]}}, null, null, $get("infraVB.ascx_userControl_RadGrid2_gdtcSharedCalendar"));

The above line seems to generate this error:

At last! Three days later I've got to the bottom of it.

Basically, the PageViewID of the RadTabStrip does not handle (.)

It accepts a . within the gui (which it may be useful to prevent).

So - for anyone else using dynamic on-load, and placing the file to load within the PageViewID of the RadTabStrip - do not place the full path.

Then within the RadMultiPage1_PageViewCreated sub, add the additional extension as below.

 

Dim userControlName As String = e.PageView.ID + ".ascx"

Well - at least I've learn't a fair bit about debugging now :)
