I'm  using the ASP.NET Ajax version 2022.2.613.4.0 HTML Chart. Its been working fine. I have not changed any code or settings. Suddenly my application started throwing the JavaScript error below.  I have verified that my data sources are returning the required data. Attached are the code pages.  

Grateful for any help troubleshooting and resolving this issue.

For example, in the documentation's demo (below), if George's work schedule on Monday was both 8:00-14:00 AND 16:00-18:00, could those two bars be on the same line?

I am writign a scheduler program that handles drag and drop appointment from a RadGrid. I need to pass a certain amount of data to the AdvancedInsert form via custom attributes, but I can't figure out how. I have tried using ISchedulerTimeSlot.FormContainer.Appointment.Attributes and ISchedulerTimeSlot.Appointments[0].Attributes but in both cases null is returned and crash the program. I am trying to use the AdvancedInsertTemplate inline rather than via a usercontrol and controlling the form via the FormCreated method.

My current code:

        
protected void AppointmentList_RowDrop(object sender, GridDragDropEventArgs e)
        {
            GridDataItem dataItem = e.DraggedItems[0];

            string id = (string)dataItem.GetDataKeyValue("ID");
            string customer = (string)dataItem.GetDataKeyValue("Customer");
            string title = (string)dataItem.GetDataKeyValue("Title");
            string jobtype = (string)dataItem.GetDataKeyValue("JobType");
            string targetSlotIndex = TargetSlotHiddenField.Value;

            if (targetSlotIndex != string.Empty)
            {
                HandleSchedulerDrop(id, title, customer, jobtype, targetSlotIndex);
                TargetSlotHiddenField.Value = string.Empty;
            }

            ISchedulerTimeSlot slot = AdeoJobScheduler.GetTimeSlotFromIndex(targetSlotIndex);
            AdeoJobScheduler.ShowAdvancedInsertForm(slot.Start);
// Pass extra details for JobType, Subject here

        }

        protected void AdeoJobScheduler_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
        {
            RadScheduler scheduler = (RadScheduler)sender;

            if (e.Container.Mode == SchedulerFormMode.AdvancedInsert || e.Container.Mode == SchedulerFormMode.AdvancedEdit)
            {

                RadDateTimePicker startInput = (RadDateTimePicker)e.Container.FindControl("StartInput");
                startInput.SelectedDate = AdeoJobScheduler.DisplayToUtc(e.Appointment.Start);

                RadDateTimePicker endInput = (RadDateTimePicker)e.Container.FindControl("EndInput");
                endInput.SelectedDate = AdeoJobScheduler.DisplayToUtc(e.Appointment.End);

                RadMultiSelect fitterlist = (RadMultiSelect)e.Container.FindControl("SelectFitters");

                foreach (Fitter.Result fitter in GetFitters().GetAwaiter().GetResult().results)
                {
                    MultiSelectItem newFitter = new MultiSelectItem() { Text = $"{fitter.properties.firstname} {fitter.properties.lastname}", Value = fitter.properties.id };
                    fitterlist.Items.Add(newFitter);
                }

            }
        }

Any help greatly appriciated.

I have a RadGridView that fits my page as expected utilizing the width property.

But when I set the AllowFilteringByColumn to "True" the grid now expands past the width property.

It first draws on the screen in proper width, then at the end expands way past width.

Using Version 2019.2.514.40

I have tried setting render mode to "Classic", "Lightweigt" but get exact same problem.

See picture below.  You can see all columns when I set to False, but when I set to True, you cannot see all columns, you

now have to scroll a lot to see them all.

When I click save, I want the grid to specify the column and pop up the required prompt box. Please!

If shown, I want to modify the data source and click Save to send the parameters in the text box above to the background. How to achieve this!

Hello everyone,

I've been trying to find a way to add my company's logo to the RadMenu, on the left side, just like we see on almost every website. You check the attached image to have a better idea about what do I exactly mean.

Thank you!

Hi all,

So I'm trying to reconfigure a page to load ASP.NET content inside an ajaxed tabstrip instead of reloading the page every time the tab is changed. 

Unfortunately, the built in Telerik function is having trouble finding the radgrid on the page when it is within the AJAX frame:

We have a strange issue where when we copy and paste from Word to the Telerik Editor (2018.3.910.45) using Firefox on a Mac (running 12.4). that the editor inserts a large <style> tag with a font face element inside. See Attached Screenshot. This is only the case when using a Mac and Firefox. I can recreate the issue on the Telerik Demo page. https://demos.telerik.com/aspnet-ajax/editor/examples/cleaningwordformatting/defaultcs.aspx

Any thoughts on how to fix this would be most appreciated. Thanks! We tried utilizing the ConvertFontToSpan and ConvertInLineStylesToAttributes options in the content filter.
