Hi , currently working on a dashboard to display some data and need to display the Scheduler timeline view , but the problem is that the timeline width is too wide and you need to scroll to view events in the evening .

How to make the timeline view to fit the container?  as this is going to be display on a dashboard with no user interface (to scroll ).

Using Blazor 9 and latest kendo UI .

Thanks

Hi, I was working through converting a grid to TelerikGrid, referencing this document page:

https://www.telerik.com/blazor-ui/documentation/components/grid/editing/popup

Using GridEditMode.Popup.

Edit and Delete functionality was working.

New record functionality, however, was not.  It was triggering the correct dialog editing, but wouldn't trigger a dialog for adding a new record.  Instead it would fire my database code to add a record, with null data being passed.

I eventually figured out the example uses the OnCreate event, and I was using the OnAdd event.

This wasn't obvious to me, and there didn't seem to be anything in the documentation indicating you have to use OnCreate for the dialog to appear?

I then found this page which has more details on the events:

https://www.telerik.com/blazor-ui/documentation/components/grid/editing/overview

In the events section of the page, it states:

-

• OnAdd - fires when the Add command button for a newly added item is clicked. The event is cancellable.
• OnCreate - fires when the Save command button for a newly added item is clicked. Cancellable (cancelling it keeps the grid in Insert mode).
  

-

This isn't helpful either, and I'd go so far as to say it's incorrect?

If you have a GridCommandbutton like this:

<GridToolBarTemplate>
    <GridCommandButton Command="Add" Icon="@SvgIcon.Plus">Add New</GridCommandButton>
</GridToolBarTemplate>

And you are handling the OnAdd event, the event fires without giving the user a popup, and the data passed in the event is a null item.

If you are handling the OnCreate event, the user gets a popup, however the button to "add" is actually Update:

As you can see, there's neither an Add button to click or a Save button to click.

Perhaps this documentation is correct for other edit modes, but it seems to be misleading or flat out incorrect for Popup mode?

On a side note, the documentation also seems to switch back and forth between saying CUD and CRUD.  I can sort of understand why you omit the Read part, but it makes the documentation confusing and I'm not sure you correctly use CUD and CRUD in all the right places.  Furthermore, every other database documentation I've seen says CRUD, Read or not!

Hi,

I'm sure I'm being stupid but could anyone help with why the following classes are inaccessible when I try to follow the example at https://www.telerik.com/blazor-ui/documentation/knowledge-base/grid-custom-cell-formatting-with-radspreadstreamprocessing#custom-cell-formatting-of-the-exported-file-with-radspreadstreamprocessing ?

It's not like they are completely unrecognised, just inaccessible due to their protection level.

What am I missing?

Thanks,

Dean

Hi,

in my existing project I use custom filter rows for the grid:

<GridColumn Field="@column.DbName" FieldType="@type" Title="@column.HeaderName.Sanitize()" Width="@(column.DbName == nameof(Worker.BinderId) ? "230px" : "200px")" Lockable="true">
    <FilterCellTemplate>
        @if (type == typeof(string))
        {
            <CustomTextRowFilter Context="@context"/>
        }
        else if (type == typeof(int) || type == typeof(int?) || type == typeof(decimal) || type == typeof(decimal?))
        {
            <CustomNumberRowFilter Context="@context"/>
        }
        else if (type == typeof(DateTime) || type == typeof(DateTime?))
        {
            <CustomDateRowFilter Context="@context"/>
        }
        else if (type == typeof(bool) || type == typeof(bool?))
        {
            <CustomBooleanRowFilter Context="@context"/>
        }
    </FilterCellTemplate>

Furthermore I use the OnStateInit and OnStateChanged events so save and restore user settings for filters, groupings etc.

private async Task OnStateInitHandler(GridStateEventArgs<object> args)
{
    ShowSpinner = true;
    var stateValue = await AppStateService.GetAppStateAsync(SelectedProjectGuid, CurrentUser.Id, AppStateType.GridWorkerState);

    if (!string.IsNullOrWhiteSpace(stateValue))
    {
        var state = AppStateHelper.GetItem<GridState<object>>(stateValue);

        if (state != null)
        {
            await CleanGridState(state);
            args.GridState = state;
        }
    }

    ShowSpinner = false;
}

With the filter's initialization I set the value and operator:

protected override Task OnInitializedAsync()
{
    Field = ((FilterDescriptor) Context.FilterDescriptor.FilterDescriptors[0])?.Member;
    SetValue(((FilterDescriptor)Context.FilterDescriptor.FilterDescriptors[0]).Value);
    SetOperator();
    return base.OnInitializedAsync();
}

Up to now every time the grid was loading the filter values have been set correctly and the grid has filtered the records.

Now, after updating to a new Telerik version, the grid still filters correctly. But the filter component doesn't get the values and so doesn't show them.

The reason is:

Before update the process was... Init grid -> OnStateInit -> Init filter component

Now it is... Init grid -> Init filter component -> OnStateInit

So, the grid state is pulled too late.

Has the init sort order been changed? How can I get this solved?

Best regards,

Rayko

Hello, 

I am currently experimenting with the ChipList component and the documentation suggests that it delivers the same customization options as the Chip component. However, I am unable to find a way to change the ThemeColor of the chips. Is this feature supported, and if so, how can it be implemented?

Reference that suggests this is possible: Blazor ChipList

Customization

Thanks

Hi,

in a Blazor Grid with Column Virtualization and multiple ow selection enabled, when I use the "Select all" option the column virtualization doesn't load any further values on scrolling.

I took an example from the Telerik docs and added a checkbox column:

Is there any solution for this?

I'm trying to reference a TelerikComboBox in a razor component, but it keeps returning null.
(I'm using version 6.2.0)

Any clues?

Html:

<TelerikComboBox Class="hide-combobox-buttons" 
                 Data="@AllLabels" 
                 Value="@Label"
                 @ref="ComboBoxRef"
                 ValueChanged="@((string newValue)=> ValueChanged(newValue))"
                 AllowCustom="true">
</TelerikComboBox>

@code{

 private TelerikComboBox<string, string>? ComboBoxRef { get; set; }

 [Parameter]
 public IReadOnlyList<string>? AllLabels { get; set; }

 private string Label { get; set; } = string.Empty;

 protected override async Task OnInitializedAsync()
 {
     if (ComboBoxRef != null) //here it's always null
         await ComboBoxRef.FocusAsync();

     await base.OnInitializedAsync();
 }

}
