VS extension error while creating solution with template and preexisting solutions no longer function. Persists through reinstall

I am getting this error every time I go to create a new solution from the Telerik asp.net AJAX web app template. My preexisting solutions will also no longer function. It seems they can't find most of the telerik assemblies. I first tried to repair the installation; I then tried uninstalling and re installing the telerik asp.net AJAX package. I'm getting the same error as before.

Any help would be greatly appreciated.

Error occurred while running wizard.

Hide version in HTML source

Hi,

How we can hide the version of Telerik currently installed from the HTML source?
We don't want to show this information at client side to prevent the hackers can use vunerabilities known in the version we used/installed in our applications.

If we check the HTML source, we see the following:
- 
- Telerik.Web.UI%2c+Version%3d2018.2.710.45 in Telerik.Web.UI.WebResource.axd

Expanding recurrence in C# instead of using SQL UDF.

Hello!

Is there possibility to expand RecurrenceRule in C# instead of using SQL UDF (provided here: http://www.telerik.com/community/forums/aspnet-ajax/scheduler/sql-reporting-display-all-recurring-appointments.aspx)?

For example I have List of type Appointment and I want to expand Recurrences in elements which have RecurrencyRule != null so the result will be List of upcoming events ordered by Start attribute.

Is this possible?

Thanks in advance

EDIT:

I've opened ExpandRecurrence_UDF zip file from post about SQL UDF and I've found function which returns occurences for RecurrenceRule string but when I try to parse my RecurrenceRules which are being parsed by SQL UDF function I can't get this make to work under C#.

Function:

    
                    public static IEnumerable ExpandRecurrence(string recurrenceRule, DateTime rangeStart, DateTime rangeEnd) 
        
                    { 
        
                        List<OccurrenceInfo> occurrences = new List<OccurrenceInfo>(); 
        
                        RecurrenceRule rrule; 
        
                        if (RecurrenceRule.TryParse(recurrenceRule, out rrule)) 
        
                        { 
        
                            rrule.SetEffectiveRange(rangeStart, rangeEnd); 
        
                            foreach (DateTime occStart in rrule.Occurrences) 
        
                            { 
        
                                OccurrenceInfo info = new OccurrenceInfo(occStart, occStart.Add(rrule.Range.EventDuration)); 
        
                                occurrences.Add(info); 
        
                            } 
        
                        } 
        
                        return occurrences; 
        
                    }

Occurences class:

    
            public class OccurrenceInfo 
        
            { 
        
                private DateTime start; 
        
                private DateTime end; 
        
                public OccurrenceInfo(DateTime start, DateTime end) 
        
                { 
        
                    this.start = start; 
        
                    this.end = end; 
        
                } 
        
                public DateTime Start 
        
                { 
        
                    get { return start; } 
        
                    set { start = value; } 
        
                } 
        
                public DateTime End 
        
                { 
        
                    get { return end; } 
        
                    set { end = value; } 
        
                } 
        
            }

Sample RecurrenceRule string which I'm tryign to parse:

    
            RecurrenceRule.TryParse("DTSTART:2008422T000000Z\nDTEND:2008423T000000Z\nRRULE:FREQ=YEARLY;INTERVAL=1;BYMONTHDAY=22;BYDAY=MO,TU,WE,TH,FR,SA,SU;BYMONTH=04\n", out rrule)

I've tryed to use Replace function to convert \n to Environment.NewLine but it was returning false too.

EDIT2: I've found bug in my RecurrencyRule string. Month in DTSTART and DTEND was in X format (for months 1-9) instead of XX

After installing Visual Studio 2019 and Reporting Services, then installing UI ASP.NET 2020_3_1021, visual studio crashes with a "Not Responding" when opening any reporting solution/project. Is there a conflict with versions?

Get mouse location on Click (and zoom + rotatation)

Hi,

We have a solution that users can use either with a Windows solution or with a Web browser.

With your great support, we were able to add PushButtonField to a PDF file with Windows Forms solution.

Is this possible also with Ajax version? To get a mouse location, zoom and information if document is rotated. I'm really bad with Javascript.

Thanks in advance for your great support!

How to input data without triggering OnClientChange event

Hello,

I am trying to create a spreadsheet where users can input data to a formatted sheet. The changes are written to database and then the spreadsheet values are changed according to data inputted. But writing data with Javascript triggers the event again. Locking the OnClientChange method is one way I accomplished this, but rapid changes don't get recognized and are ignored. Is there a better way of fixing this issue?

Thanks for any help in advance :D

Disable value changes when dragging cells

How do I stop values from changing when dragging cells. In the provided example, the values iterate trough day abbreviations (the days are in Lithuanian language. Translations of the day abbreviations would be: friday, saturday, sunday, monday, tuesday). What is weird is that I can't replicate it in English or Russian.

Thanks for any help provided! :D

Radgrid/WebResource JS Exceptions

I have a very simple ASP.net web form with a couple of data pickers, a button and a radGrid. When I initially load the page the grid is not populated and is dependant on both date pickers having selected values. When I click the "Refresh" button to set the radGrid datasource (the result of a stored procedure with two parameters), I noticed that none of the grid filters worked. Upon further investigation I see that there are a couple of uncaught errors (see the attached image).

I am using version 2020.3.1021 of the ASP.net controls so there isn't any outstanding updates. Other grids work as expected.

Can you advise?

telerik:RadEditor - undefined error when clicking on controls

We're using a telerik:RadEditor and have just updated to .Net 4.7.2.

When we click on some of the controls, e.g. the "strip formatting" control, then we sometimes (not always) get the following error shown in the Browser's console "Cannot read property 'trim' of undefined".

We're running version 2014.1.403.35 of the Telerik.Web.UI. We know that there are newer versions available but don't want to have to upgrade if this is not required.

Two errors are as follows:

loading.gif not displayed in RadAjaxLoadingPanel with Internet Explorer

Hi, I have a RadAjaxLoadingPanel which has a gif image loaded by GetWebResourceUrl function. When I make an ajax postback the loading panel is displayed (a gray panel covering all the controls in the page) but the gif inside the loading panel is not displayed. This only happens with Internet Explorer 7-8. It works fine with Firefox, Safari and Chrome.

    
                <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel" runat="server" BackColor="#E0E0E0" 
        
                    Transparency="20"> 
        
                    <table style="width: 100%; height: 100%;"> 
        
                        <tr style="height: 100%;"> 
        
                            <td style="width: 100%; text-align: center; vertical-align: middle;">                
        
                                <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>' 
        
                                    style="border-right: 0px; border-left: 0px; border-top: 0px; border-bottom: 0px;" /> 
        
                            </td> 
        
                        </tr> 
        
                    </table> 
        
                </telerik:RadAjaxLoadingPanel> 
        
                <telerik:RadAjaxPanel ID="RadAjaxPanel" runat="server" LoadingPanelID="RadAjaxLoadingPanel"> 
        
                 <div style="width:500px; height:500px"> 
        
                 </div> 
        
                </telerik:RadAjaxPanel>

I have all the necessary web.config entries

<add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />
<add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" />

PS: When I check the telerik web pages (such as http://demos.telerik.com/aspnet-ajax/ajax/examples/loadingpanel/loadingimages/defaultcs.aspx) running with RadAjaxLoadingPanel my internet explorer browser successfully shows the gif images. So I think this is not related to internet explorer configuration.

Thank you...
