WebListBox generates error when removing items

NBPSupport_DBillings — Mon, 13 Mar 2017 13:28:05 GMT

I have two WebListBoxes, one for Available Items and another for Selected Items. The design goal is for the user to select items from one list box and transfer them to the other. This means the code must (a) detect the selected items in one list, (b) copy the selected items to the other list, and (c) delete the selected items from the first list. I can do (a) and (b) but the page crashes if I try (c).

Here's the code for the user control (which contains the two list boxes) and the page that uses the control:

        End If

    End Sub

End Class

When I run the program I get items 1 through 10 in the Available Items list and items 11 to 13 in the Selected Items list. If I choose the first 3 items of the Available List and click the Move Right button (top one) the page crashes with the attached error. NOTE: There is commented code in the user control that tries to clear the items. You have to uncomment some of that to see the error.

Is there a way to remove items from a WebListBox without invoking a page crash?

WebCalendar multiple selection lost its ability

sjain — Wed, 06 Apr 2016 15:07:54 GMT

Hi,
We recently upgarded our applilaction with new version of controls of Intersoft. In this version WebCalendar lost its multiselect functionality and on click on any date increase the date cell's height. Intersoft provided 2 sample files; one as "ISNet.WebUI.Samples" and second as "WebUI.Unified.Samples" . Multiple selection is working in "WebUI.Unified.Samples" but not in
"ISNet.WebUI.Samples". I modified both sample's AcademicCalendar.aspx pages and attaching for your view. Also second issue can be replicated on your live sample site also. Just Click on a date several time and you will see the issue. link is http://live.intersoftsolutions.com/cs/WebEssentials/WebCalendar/RangeOfChart_MetroStyle.aspx?noframe=1&path=/WebEssentials/Calendar .

May be someone would suggest that we should use Unified theming but that is not solution. It should work for intersoft samples. Changing them require a lot of testing prior to deploy to client side and after getting new version of controls our planner pages are not working for miltiple selection. Live sample was checked on Window 10 pro IE 11 where attached samples are on IE 10.
Can you look on the issue that what should need to do for WebCalendar multiple selection and height issue !
regards
Sachin

First week of year not correct in 2015

aliard@sigma-rh.com — Fri, 17 Apr 2015 17:38:16 GMT

Hi We use the 2 settings below:

CalendarSettings.FirstWeekOfYear = WebSchedulerFirstWeekOfYear.First4DayWeek;

CalendarSettings.FirstDayOfWeek = DayOfWeek.Monday;

Normally the week starting on january 29th 2015 has 4 days in 2015 and should be considered as the first week of the year but it is not. It is shown as the 53th of 2014.

Webcalendar does not display all months when used in a dialogbox

shresta — Wed, 01 Apr 2015 08:17:17 GMT

Hi Intersoft,

We are using webcalendar in a webdialog which is Integrated to desktop.

When we use the multicalendar feature(eg: NumberOfCalendarDisplayed=6'), few months does not get displayed as the height and width of the calendar exceeds the dimension of webdialog. Is it possible for the webcalendar to float outside the webdialog frame such that all the 12 months get displayed?

Thanks,

Shresta

WebCalendar disable past dates

devashish — Thu, 19 Feb 2015 12:11:00 GMT

Hi,

Is there any way I can disable the past dates in WebCalendar i.e. the user can only select the present date or a future date.

Something like booking a flight where user can only select today or a day in future.

Ans also can you tell how to make the disabled date look different.

Regards,
Dev

WebCalendar holiday are repeated on every year

aliard@sigma-rh.com — Thu, 15 Jan 2015 21:54:08 GMT

Hi,

We have a problen with holidays in the WebCalendar. Actually, when we add a holiday in the list, it shows up every year not only the year of the date we created it.

It is a problem for us as many holidays are base on day of week like for example Thanksgiving which is the fourth Thusday of November. So we have the holiday on Nov 27th 2014 but Nov 26th 2015.

If we add Nov 24th 2014, the calendar will show a holiday on every Nov 24th no matter the year we look to.

What are we doing wrong?

Regards,

Alex

WebCalendar Deployment Error!

sample4170 — Mon, 15 Dec 2014 13:16:19 GMT

Hi,

I have recently deployed a project in IIS 7. I am using WebGrid, WebDesktop and WebCalendar in it. I've a virtual directory added to CommonLibrary in IIS 7. I've the ISNet.dll, ISNet.WebUI.dll, ISNet.WebUI.Resources.dll and ISNet.WebUI.[product].dll/ISNet.WebUI.[product].Resources.dll; As well as the XML files. For the WebGrid, I've added ISRes and ISChart http handlers as well, along with WebInput and Run-time license keys for all the three components.

Now the issue is, InitWebCalendar Component is throwing JavaScript error: Object Required. I know this as an issue which occurs only when the assembly files are missing. But here, I am not able to find any mistake on this side. Can you please provide a solution for this as soon as possible? This is really urgent and would like to know what is missing. Thanks in advance.
