I have an animationcontainer which I in overridden OnAfterRenderAsync(bool firstRender) call:
await AnimationContainerSettings.ShowAsync();...since it is the only way to show the AnimationContainer from start. However, when I in some cases return to the page, the animationcontainer will only show itself if I delay the call with e.g. 1000 ms:
await Task.Delay(1000);
await AnimationContainerSettings.ShowAsync();What could be possible reasons for this be? If I want my AnimationContainer to be visible as default when page is either Initialized or after rendering has occured, where and how should I call ShowAsync()?

When I create multiple tabs and each tab has the same type of component, the OnInitialized is only running for the first one I click on.
Here is a simplified example to demonstrate:
MAIN PAGE:
@page "/tabtest"
@using Telerik.Blazor.Components
<div>Product XYZ</div>
<TelerikTabStrip TabPosition="Telerik.Blazor.TabPosition.Top" @ref="productTabStrip" @bind-ActiveTabIndex="@ActiveTabIndex">
<TabStripTab Title="Details">
<div class="container sms-tab-content">
GENERAL PRODUCT INTRO STUFF HERE
</div>
</TabStripTab>
@foreach (var item in listOfWidgets)
{
<TabStripTab Title="@item.WidgetName" Disabled="false">
<Widget WidgetID="@item.WidgetID" WidgetName="@item.WidgetName" />
</TabStripTab>
}
</TelerikTabStrip>
<div style="margin-top: 15px;">
<div><b>Below is a flat non-tab example of repeating widgets:</b></div>
@foreach (var item in listOfWidgets)
{
<Widget WidgetID="@item.WidgetID" WidgetName="@item.WidgetName" />
}
</div>
@code {
Telerik.Blazor.Components.TelerikTabStrip productTabStrip;
public int ActiveTabIndex { get; set; } = 0;
protected class Widget
{
public int WidgetID { get; set; }
public string WidgetName { get; set; }
}
private List<Widget> listOfWidgets = new List<Widget>();
protected void GetData()
{
listOfWidgets.Add(new Widget { WidgetID = 1, WidgetName = "Cog" });
listOfWidgets.Add(new Widget { WidgetID = 2, WidgetName = "Wheel" });
listOfWidgets.Add(new Widget { WidgetID = 3, WidgetName = "Bloof" });
}
protected override void OnInitialized()
{
GetData();
}
}
WIDGET COMPONENT:
@page "/widget/{WidgetID:int}/{WidgetName}"<div>
<div>@WidgetID</div>
<div>@WidgetName</div>
<div>@ExtraWidgetInfo</div>
</div>
@code {
[Parameter] public int WidgetID { get; set; } = 0;
[Parameter] public string WidgetName { get; set; } = "Nothing";
private string ExtraWidgetInfo { get; set; } = "Stuff";
protected override void OnInitialized()
{
if (WidgetName == "Cog")
ExtraWidgetInfo = "This is good info about cogs.";
if (WidgetName == "Wheel")
ExtraWidgetInfo = "This is good info about wheels.";
if (WidgetName == "Bloof")
ExtraWidgetInfo = "This is good info about bloofs.";
}
}
Looking for feature parity with - https://www.telerik.com/kendo-react-ui/components/grid/data-operations/odata-server-operations/
ADMIN NOTE: The goal is to expose a method like args.Request.ToODataString() for the grid OnRead event, so you can pass this on to a service so it knows the grid state (page size, current page, filtering,..). The grid will still expect the total of items and the current page of data to be set in the local fields.
Our grids / drop downs / comboboxes pull 1000s of items, resulting in JSON of 20mb+ if we pull all of the elements to the client. The OData server operations have greatly reduced what we send over the wire, and have worked amazing well in our current React application. Would love to have the same capability for Blazor client side. We are treating Blazor as a client side replacement for React/Redux, we do not want to run Server Side Blazor.
We’ve the use case of an editable combo-box and until now, we used to it with a textbox and a gridview to achieve this with your components.
On the demo page, when I hover over menu items "Overview" and "Demos" and "Roadmap" it changes background color to gray. When I load it into a project with the verbatim demo code no background color change occurs except on "Roadmap".
<TelerikMenu Data="@MenuItems"
ParentIdField="@nameof(MenuItem.SectionId)"
IdField="@nameof(MenuItem.Id)"
TextField="@nameof(MenuItem.Section)">
</TelerikMenu>
@code {
public List<MenuItem> MenuItems { get; set; }
public class MenuItem
{
public int Id { get; set; }
public int? SectionId { get; set; }
public string Section { get; set; }
}
protected override void OnInitialized()
{
MenuItems = new List<MenuItem>()
{
new MenuItem()
{
Id = 1,
Section = "Overview"
},
new MenuItem()
{
Id = 2,
Section = "Demos"
},
new MenuItem()
{
Id = 3,
Section = "Roadmap"
},
new MenuItem()
{
Id = 4,
SectionId = 3,
Section = "What's new"
},
new MenuItem()
{
Id = 5,
SectionId = 3,
Section = "Roadmap"
},
new MenuItem()
{
Id = 6,
SectionId = 3,
Section = "Release History"
}
};
base.OnInitialized();
}
}
Hello Team;
I'd like to suggest to offer us an easy way to use the different themes offered by Bootswatch (bootstrap themes) during development and also allow us to offer that capability to our user, so they can pick their own theme.
Hope this helps!
Thanks!

In release 2.0.0 it was possible to set default property Visible to "true" for AnimationContainer. That is now gone. How do I make the AnimationContainer visible per default, i.e without calling ShowAsync() in some stage?

Hi.
Because https://feedback.telerik.com/kendo-jquery-ui/1360369-blazor-ooui is not closed I am now suggesting that you make controls for the Uno UI platform and Ooui.
Ooui and Uno are both known in context with Web Assembly and I think you should make controls for both.
You should also consider making controls for Ooui server side. If I could choose from all the worlds' options to build a web application, I would use Ooui server side, if it wasn't because of the lack of controls. The server side option is so simple to use and it was actually the reason Frank Krueger created it to begin with. He wanted a super simple way to display something on the web and he achieved that.

Did I miss installing something.
Used the installer telerik.ui.for.blazor.2.1.0.commercial.msi
An important (3 actually) components that we require heavily in our (to make sure we collect data accurately), are a good Date, Time and Date/Time Combo picker.
In any business app, Date/Time can be very crucial piece of data that needs to be collected from user correctly and visually, especially on smaller devices.
Could you please consider these 3 data pickers that can be bound to the model?
Thanks in advance.

A basic Menu control is one of the most fundamental common controls .... Why was it not included in the first release of UI for Blazor???
How about a basic fundamental Menu control in the UI for Blazor? If not now, when?
You may get an exception like
InvalidOperationException: The current thread is not associated with the Dispatcher. Use Invoke() or InvokeAsync() to switch execution to the Dispatcher when triggering rendering or modifying any state accessed during rendering.
or you may get components that simply don't work (for example, a Window does not show, a treeview does not expand).
The solution is to revert to the RenderComponentAsync method in your _Hosts.cshtml file.
If filtering is enabled, the error may prevent the view from rendering similar to NotImplementedException: Unexpected frame type during RemoveOldFrame: None.
Without filtering, an exception is thrown when you attempt to edit a field, similar to Error: System.InvalidCastException: Unable to cast object of type 'System.String' to type 'System.Nullable`1[System.Int64]'.
Using the new Grid grouping feature in 1.6, the Grouping button and the group header row both use the field name of the group column, rather than the title. This is visible in the animated demo, where a column titled "On Vacation" becomes "IsOnLeave" once it is used as a group name.
I expect this is already known and slated to be fixed, but there aren't any grouping issues at all in the public tracker, so just in case...
