Issues during Version Upgrade to R1 2020 (2020.1.114)

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.

Global Nav with RadMenu open in new window not working

We have replaced the regular Sharepoint 2010 Global Nav menu with the Telerik RadMenu. When a new link is added to the Global Nav and the "Open in new window" option is selected, clicking on that new link in the Global Nav does not open the link in a new window. Is there a setting that I am missing or is this a bug? Is there a workaround?

Thanks

Rebind/ Refresh RadScheduler on closing RadWindow

Hi,

I have a custom edit form. I open it up by setting OnClientAppointmentEditing="OpenEditSchedulePopup".

In my page I have some dropdownlists which are used to filter the data in the RadSchedule. I use a RadAjaxManager so that when the dropdown selection is changed the RadSchedule is updated via Ajax.

I would like to get the same effect when the Custom Edit Popup is closed. I have noticed that when the standard edit form is closed it uses Ajax to rebind the RadScheduler. How do I get my custom Edit popup form to use ajax to update the radscheduler when it is closed?

The standard edit form is doing it so I am sure it is possible.

Odd problem with edge

Hi,

I am responsible for a web forms applications which has been working fine for quite a while. We've gotten to IE 11 and we've started having problems. So we changed to edge and found other problems. IE 11 was sending an enter key on a save of screen which caused problems with the applications. Once we changed to Edge we encountered even weirder problems:
1. We have a number of telerik dropdowns (radComboBox). There are a few that, if they are changed to the non default values, shift back to the default value when save button is clicked. The weird thing is that this is only happening on two of the dropdowns, always the same two. The other drop downs that are working fine (which is most of them, as many as fifty). So these two that aren't working are "random". This is the second time we've found something like this. This is happening on two web forms
2. We switched to the same web form and used IE 11. The problem went away.

In both cases where this happened this has happened with random dropdowns. However it always happens with the same two dropdown. Just to clarify, all the dropdowns, the ones that work and the one's that don't, have exactly the same two values in them:
"GO"
"No GO".

Any help would be appreciated.

Thanks,
Neil Newton

Problem with radmultiselect and redis

Hi

I'm a few days trying to solve a strange behavior with radmultiselect, but without success.

I have a page works fine for very years, but now I added a new control, the radmultiselect. When I use in production Redis with distributed session/cache provider, the page crash. Many strange behaviors occurs. When I use inproc, everything works fine.

I added the radmultiselect dinamicaly like this example:

Telerik.Web.UI.RadMultiSelect rms;

rms = new RadMultiSelect();

rms.ID = "xyz";

rms.DataTextField = "text";

rms.DataValueField = "value";

rms.Filter = RadMultiSelectFilter.Contains;

rms.MinLength = 3;

rms.Font.Size = FontUnit.Small;

rms.Width = Unit.Percentage(70);

rms.AutoBind = false;

rms.AutoPostBack = true;

rms.WebServiceClientDataSource.PageSize = 20;

rms.WebServiceClientDataSource.AutoSync = true;

rms.WebServiceClientDataSource.AllowPaging = true;

rms.WebServiceClientDataSource.EnableServerPaging = true;

rms.WebServiceClientDataSource.EnableServerFiltering = true;

rms.WebServiceClientDataSource.EnableViewState = true;

rms.WebServiceClientDataSource.WebServiceSettings.Select.DataType = ClientDataSourceDataType.JSON;

rms.WebServiceClientDataSource.WebServiceSettings.Select.ContentType = "JSON";

rms.WebServiceClientDataSource.WebServiceSettings.Select.Url = f.FixupUrl("~/dal/webservices/service.asmx/getTags");

rms.Enable = true;

"name of placeholder".Controls.Add(rms);

The problem occurs when I try to add the database value.

I tried some formats:

1 - Dynamic list

List<dynamic> selected = new List<dynamic>();

foreach (DataRow dr_rms in dt_rms.Rows) {

MultiSelectItem msi = new MultiSelectItem();

msi.Value = dr_rms["value"].ToString();

msi.Text = dr_rms["text"].ToString();

rms.Items.Add(msi);

var item = new {

text = dr_rms["text"].ToString(),

value = dr_rms["value"].ToString()

};

selected.Add(item);

}

rms.Value = selected;

2 - Fixed Class

public class RadMultiSelectClass {

public int value { get; set; }

public string text { get; set; }

}

List<RadMultiSelectClass> selected = new List<RadMultiSelectClass>();

foreach (DataRow dr_rms in dt_rms.Rows) {

selected.Add(new RadMultiSelectClass { value = Convert.ToInt32(dr_rms["value"].ToString()), text = dr_rms["text"].ToString() });

}

rms.Value = selected;

webconfig:

Everything works fine:
The radmultiselect get the value from database and the page flow are totaly normaly. With many postbacks, everything works fine.
<sessionState mode="InProc" cookieless="false" timeout="120" />

Page with strange behaviors, loosing sessions.
<sessionState mode="Custom" customProvider="MySessionStateStore">
<providers>
<add name="MySessionStateStore" type="Microsoft.Web.Redis.RedisSessionStateProvider" host="xxx.cache.amazonaws.com" port="6379" accessKey="" ssl="false" retryTimeoutInMilliseconds="60" throwOnError="false" />
</providers>
</sessionState>

If I comment the "// rms.Value = selected;" The page works fine, with or without redis. The problem only occurs when I put some value to rms.value.

The RadMultiSelect.Value have any problem with Redis or distributed session provider?

Thanks
