I am trying to populate a RadComboBox dynamically based on the selected of another RadComboBox in EditFormSettings.

Here is a code snippet of what I'm trying to do:

                                    </telerik:RadGrid>

My Codebehind for the IndexChanged event is:

Protected Sub rcbWorkGroup_IndexChanged(sender As Object, e As RadComboBoxSelectedIndexChangedEventArgs)
        Dim x = 1

End Sub

I will hit the breakpoint when the workgroup is selected but I do not know how to fill the workgroupoptions combo in the SelectedIndexChanged sub.

Hi,

I'm trying to use the RadAutoCompleteBox under one of our asp.net webforms and I'm having an issues,

We have a large set of data with more then 12000 records.

At first i was trying to load all the records and bind it to the control on each page load on the server side, that was working quite good on desktop browsers but in mobile browsers it was awful as the browser can't handle an 12000 html tags and javascript data rendered by the control.

Also it came up that the page weight around 4.5MB which is a lot even for a desktop browser.

So I was trying to follow the documentations at https://docs.telerik.com/devtools/aspnet-ajax/controls/autocompletebox/data-binding/binding-to-web-service and write a web service which will load all my records and then filter them according to the user input and then return the filtered results to him at this point after struggling with the webservice code as I couldn't use the AutoCompleteBoxData  and i had to write my own context class and data item class, I was able to see that the webservice does works and returns results according  to the user input but the control doesn't render the results and It's throwing exception at the browser console:

the application is written in .net 4.8 and I'm using Telerik controls version 2019.3.1023.45

Can you advise what to do, how to solved it?

Thanks in advanced,

Hagai.

Folks,

Using Windows 10 with VS 2017 and Progress® Telerik® UI for ASP.NET AJAX (Version 2018.1.117.45).

Each time I download a new updates, I get attached error message.

Is taking about 2-3 days to research to find out the root cause of this error.

I manually added Telerik.Web.UI.dll and Telerik.Web.UI.Skins.dll in Bin Folder of my project. Also copied both files into C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\PublicAssemblies folder. Still no luck.

Telerik please give us a solution what can be done. 2-3 days time is not acceptable to senior management of our organization.

Thanks

Hi,

We are currently using Telerik UI ASP .NET AJAX version 2011.1.519 Utlimate suite. Now, We have downloaded & upgraded to is R1 2020 (2020.1.114). 

we are having the following issues.
1. In a page, we have fields (textboxes, dropdown, etc) and "Add" button and a grid. When we fill the data in the fields and click on Add button, the row gets inserted in the grid. But, after that, we are not able to click on any controls in the page. We are getting the following error.
Uncaught DOMException: Failed to execute 'insertRule' on 'CSSStyleSheet': Failed to parse the rule '

        /*.RadGrid_Default .rgHeader {
            color: #333;
        }'.

2. We are opening multiple modal windows as Parent and Child combinations. In this version, when we open the Window A and then, it is supposed to open Window B. But, Window B gets opened behind Window A.

Please let me know the fix for this.
