I have a wizard that on the first page a user can toggle what all pages they want to access.  It is meant to narrow down the available options to what they need.  When a user turns one of the options off, I disable that page.  I don't hide it because the functionality with the add/remove pages tends to put the newly added pages at the bottom of the wizard (which I don't want).

The next problem I run into is the functionality of the Previous / Next Buttons.  If the next or previous page is disabled, the relative button is also disabled.  Which means the user now has to click the actual step instead of clicking next.

I attempted to add my own buttons but without access to the individual steps like the default buttons have I can't determine if the steps are disabled or not.  My goal is to click the "Next" or "Previous" button and determine what the next available step (if it is non-linear) is instead of forcing the user to figure out they need to click the step in the stepper section.

There is a hack to get around this, but the business logic is not ideal, and it is very rigid.  I would prefer not to go this route.  The work around is checking all the possible combinations of variables that control the disabled option for each page.

Looking to leverage the Required data annotation on the model to apply an asterisk or other required field indicator to a FormItem's label. Is there a way to apply an html attribute/class to a FormItem automatically, that could then be used to append an asterisk to its label? Trying to avoid the need of marking Required both in the model and the UI.

I'm trying to create filter that works on two columns. The first column "IsActive" = true works properly.

I need to have a second filter on a column that filters for all "ParticipantId" that is a nullable integer type
thatis either null or empty.

Logical this would be an And

Currently this is what I have but it does not work. How would I includea filter for a null integer column using AND logic?

var filterDescriptors = new List<IFilterDescriptor> { new CompositeFilterDescriptor{ FilterDescriptors = [ new FilterDescriptor{ Member = "IsActive", Operator = FilterOperator.IsEqualTo, Value = true, MemberType = typeof(bool) }, new FilterDescriptor{ Member = "ParticipantId", Operator = FilterOperator.IsNullOrEmpty, Value = null, MemberType = typeof(int) } ] } };

I need to add more colors to my charts. The theme builder only has 7 colors. I can see in the exported file that they are in the root under --kendo-color-series a though g. I have tried adding --kendo-color-series-h but my charts won't use that 8th color. I know this is the right place cause i can change the first 7 colors and see that change. So how do I add more colors to the kendo color series?

Hello.  Is there a way to override "No Records Available" message while the page is loading, for TalerikLoaderContainer for Blazor?

Found this https://docs.telerik.com/blazor-ui/components/grid/templates/no-data-template, but I was hoping to find something that's specific for loading.

Hi everyone,

I wanted to implement a functionality of Expand/Collapse All. I had the property Expanded in the model which takes the value of true or false. I am changing the value of that property in the model but nothing happens on the interface.

Can you help me please? Can this functionality be implemented?

 

Thank you,

Cipri

Hello,

I am using TelerikScheduler, and the calendar events are generated by Microsoft Graph API. In my current logic, I retrieve an updated list of calendar events every 3 minutes. Scenario would be a user row in scheduler was double clicked, and the scheduler edit popup window is open with SchedulerResource defaulted to the selected user. If during the edit, the drop down for SchedulerResource is switched to another user, but if the updated logic in 3 minutes take place, the SchedulerResource goes back to original selected user from the double click event. Is there a way to keep the currently selected user during my updated list event?

Hi, 

I have the need to display a tooltip when my TelerikDropDownList is in error mode (css class = 'change-local-dropdown error'). However the tooltip does not show anything and when inspecting the TelerikDropDownList, no html element in the TelerikDropDownList tree has a 'title' property set. This despite me explicitly setting the Title property, as can be seen in the code below.

Here's my code


<TelerikTooltip TargetSelector=".change-local-dropdown.error" />
<TelerikDropDownList Data="@Zones"
                     AdaptiveMode="@AdaptiveMode.Auto"
                     Class="@(string.IsNullOrEmpty(_zoneError) ? "change-local-dropdown" : "change-local-dropdown error")"
                     @bind-Value="@SelectedZoneGuid"
                     TextField="@nameof(Zone.Name)"
                     ValueField="@nameof(Zone.Guid)"
                     Title="My tooltip that I want to display, but it isn't showing up"
                     Width="100%">
</TelerikDropDownList>
Any help is greatly appreciated...
