I added a TelerikWizard with five WizardSteps on a page. No child components, all code directly inside the different steps. Navigating back and forward between the steps works fine, all steps/controls keeps their user input data/state.

After a while I had so much content that I wanted refactor some of the steps into components. I made the first component and added it to one of the steps:

<WizardStep ...
<Content>
    <TransferLocationTables @ref="refTransfer" LocationId="@VM.SelectedLocation.Id" />
</Content>
...

Now when I navigate to that specific step the component is always "reset" and I have to rearrange the data loaded from the DB again, which kind of defeats the whole idea with those steps and being able to go back and forth between them.

When I go one step back I can see in the debugger that the component still got all the internal data. As soon as I go forward to that step everything is empty again. Also noticed the components overriden OnParametersSet and OnInitializedAsync methods are called each time I navigate there so clearly the whole component is "reinitialized" and thus loosing the data.

So, is this changed behavior due to that when I had all code in the TelerikWizard everything behaved as a single component and thus all data persisted (didn't really leave it), but when I add child components they will automatically reinitialize everytime their step is rendered?

I guess I could persist the individual child components state by saving it to the DB and load it everytime I enter that step again, but I'm hoping there is a simpler soluton that I've overlooked (I'm fairly new with coding Blazor but coded .NET for a long time).

In Kendo UI for ASP.NET MVC / JQuery the Grid component has the option to show a refresh icon on bottom bar / pager.  

In the blazor version i cannot see it.

Please add a builtin refresh icon on grid as done in other libraries.

I have a dozen OData Endpoints that provide all my data access. I am currently using the autogenerated OData Connected Service that uses the Microsoft OData Client to access the endpoints from services in my Blazor ServerSide app. 

The Telerik Blazor components seem to be geared around using Telerik.DataSource & Telerik.DataSource.Extensions to access the OData Endpoints directly.

Is there a best practice or method for accessing OData Endpoints with Telerik components? 

Thanks

Hi,

     When the page jumps, the appearance position of the Notification component is reset.

Calling code：

await AlertController.ShowSuccessNotification("[Complete Work Task]:Success");
NavigationController.Navigate(new WorkViewParam());

Controller code：

public static class AlertController
{
    private static Notification NotificationReference { get; set; }

    public static async Task ShowSuccessNotification(string message = "Success",int closeAfter = 60000,object icon = null,AnimationType animationType = AnimationType.Fade,NotificationHorizontalPosition horizontalPosition = NotificationHorizontalPosition.Center, NotificationVerticalPosition verticalPosition = NotificationVerticalPosition.Top)
    {
        if (NotificationReference != null)
        {
            NotificationReference.Animation = animationType;
            NotificationReference.HorizontalPosition = horizontalPosition;
            NotificationReference.VerticalPosition = verticalPosition;
            NotificationReference.Text = message;
            NotificationReference.CloseAfter = closeAfter;
            NotificationReference.Icon = icon;
            await NotificationReference.ShowSuccess();
        }
    }

    internal static void SetNotificationReference(Notification notificationReference)
    {
        NotificationReference = notificationReference;
    }


}

Notification Component Code(.razor)：

@using Telerik.Blazor
@using Telerik.Blazor.Components

<style>
    .custom-notification-parent {
        position: fixed;
        left: 50%;
        top: 20px;
        transform: translateX(-50%);
        z-index: 99999999;
    }

    .custom-positioned-notifications {
        position: relative;
        flex-wrap: nowrap !important;
    }

    .k-notification {
        box-shadow: var(--kendo-elevation-4, 0 8px 10px rgba(0, 0, 0, 0.12), 0 4px 16px rgba(0, 0, 0, 0.12));
        font-size: 16px;
    }
</style>

<div class="custom-notification-parent">
    <TelerikNotification @ref="@notification"
                         AnimationType="@Animation"
                         Class="custom-positioned-notifications"
                         VerticalPosition="@VerticalPosition"
                         HorizontalPosition="@HorizontalPosition">
    </TelerikNotification>
</div>

@code {

}

publicpartialclassNotification
{
    private TelerikNotification notification { get; set; }
    public NotificationHorizontalPosition HorizontalPosition { get; set; } = NotificationHorizontalPosition.Center;
    public NotificationVerticalPosition VerticalPosition { get; set; } = NotificationVerticalPosition.Top;
    public AnimationType Animation { get; set; }
    publicstring Text { get; set; }
    publicint CloseAfter { get; set; }
    publicobject Icon { get; set; } = null;

    public async Task ShowSuccess()
    {
        notification.Show(new NotificationModel
        {
            Text = Text,
            ThemeColor = ThemeConstants.Notification.ThemeColor.Success,
            CloseAfter = CloseAfter,
            Icon = Icon
        });
    }protected override async Task OnInitializedAsync()
    {
        awaitbase.OnInitializedAsync();
        AlertController.SetNotificationReference(this);
    }
}

When using Mini Mode for the Telerik Drawer, is there a way to make the Telerik Drawer expand/close with the @onmouseenter and @onmouseleave events?

I have the following layout...

<TelerikDrawer Data="@DrawerItems"
			   MiniMode="true"
			   Mode="@DrawerMode.Push"
			   SelectedItemChanged="((DrawerItem item) => SelectedItemChangedHandler(item))"
			   @ref="@DrawerRef"
			   Class="my-drawer">
	<ItemTemplate Context="item">
		<span class="icon-container drawer-tooltip-target" title=@item.Text>
			<TelerikSvgIcon Icon="@item.Icon" Class="drawer-icon" />
		</span>
		<span class="k-item-text">@item.Text</span>
	</ItemTemplate>
	<DrawerContent>
		<div class="content">
			@Body
		</div>
	</DrawerContent>
</TelerikDrawer>

I tried the following...

<TelerikDrawer Data="@DrawerItems"
			   MiniMode="true"
			   Mode="@DrawerMode.Push"
			   SelectedItemChanged="((DrawerItem item) => SelectedItemChangedHandler(item))"
			   @ref="@DrawerRef"
			   Class="my-drawer">
	<ItemTemplate Context="item">
		<div @onmouseenter="() => DrawerRef.ExpandAsync()"
			 @onmouseleave="() => DrawerRef.CollapseAsync()">
			<span class="icon-container drawer-tooltip-target" title=@item.Text>
				<TelerikSvgIcon Icon="@item.Icon" Class="drawer-icon" />
			</span>
			<span class="k-item-text">@item.Text</span>
		</div>
	</ItemTemplate>
	<DrawerContent>
		<div class="content">
			@Body
		</div>
	</DrawerContent>
</TelerikDrawer>

But that affects the layout as shown below, and does not appear to fully wrap the Drawer which causes the expand/collapse to be bit twitchy.

It also appears that I'm unable to attach @onmouse events to the <ItemTemplate> tag ( I get an unrecognized attribute error).

Any ideas?

I have a chart where clicking the legend for a series will toggle its visibility. However, when the series is hidden, the legend label gets becomes a very light grey, and some users struggle to see it

I can't find any particular property on any of the chart related elements that seems to be able to change the font/colour/opacity settings in that scenario.

Is there anything I've missed?

Hello,

I have a grid filterable with one column with FilterMenuType.CheckBoxList. 

I initialize a defaut filter with OnStateInit which work fine. But when I change the filter by selecting "Select all", nothing is return. It only work when I clear the filter first.

I reproduce the issue here : https://blazorrepl.telerik.com/GokJaiFR56kNGYBW07

Am I doing something wrong with the default filter or is it a bug? I can't find anything related.

Thanks in advance

I'm looking at the demo for NumericTextBox, when I hold mouse button the number only increments once.

i/ is there any plans for a setting to allow the value to keep incrementing/decrementing when the mouse is held down? This would be more useful in some instances rather than clicking hundreds of times. I know you can type but some users want ability to only use mouse.

ii/ related, is there any plans for a setting to control acceleration of how quickly the value increments/decrements based on how long mouse is held for? Eg if mouse is held longer than say 5 seconds then value changes at faster rate.

We are using a TelerikGrid which allows to filter various properties.

One of our properties is a name of Id, which is of Guid type.

Of course when we give a full Guid Id into the filter, the filter works, but as soon as we put a partial Guid value the filter breaks, because as expected, it cannot parse the given value.

Error: System.FormatException: Unrecognized Guid format.
   at System.Guid.GuidResult.SetFailure(ParseFailure failureKind)
   at System.Guid.TryParseGuid(ReadOnlySpan`1 guidString, GuidResult& result)
   at System.Guid..ctor(String g)

We have tried to convert guid value into string and then pass it into the filter, but it expects a Guid data type.

Is there a way to internally let the guid filter know, that he should expect a string value instead of Guid? Filtering after Guid doesn't really make sense, since user will most of the time just type a part of the full guid Id value.

Thank you for assistence!
