Hi there,

I'm facing a problem with charts in a tile layout. I have a TileLayout in my applicaton and added some charts (which are in another component) to it. I checked the documentation about TileLayout and resizing so I followed those steps. Please check out my code:

Razor MainPage:

<TelerikTileLayout Columns="5"
           ColumnWidth="300px"
           Reorderable="true"
           Resizable="true"
           OnResize="TileItemResize">
    <TileLayoutItems>
        <TileLayoutItem HeaderText="My Item Text" RowSpan="2">
            <Content>
                <TurnoverComparisonWidget @ref="TurnoverComparisonRef" SelectedWidget="widget" IsLoad="true"></TurnoverComparisonWidget>
            </Content>
        </TileLayoutItem>
    </TileLayoutItems>
</TelerikTileLayout>

Razor TurnoverComparisonWidget:

<TelerikChart @ref="ChartRef" Height="100%">
    <ChartTooltip Visible="true"></ChartTooltip>

    <ChartSeriesItems>
        <ChartSeries Type="ChartSeriesType.Column" Data="ChartData" Field="@nameof(ChartDataItem.Value)" CategoryField="@nameof(ChartDataItem.CategoryName)">
            <ChartSeriesLabels Visible="true" Format="{0:C2}"></ChartSeriesLabels>
        </ChartSeries>
    </ChartSeriesItems>
</TelerikChart>

C# MainPage:

public TurnoverComparisonWidget TurnoverComparisonRef { get; set; }

private void TileItemResize()
{
    TurnoverComparisonRef.Refresh();
}

C# TurnoverComparisonWidget:

public TelerikChart ChartRef { get; set; }

public void Refresh()
{
    ChartRef.Refresh();
}

But the chart is not resizing when I resize the tile layout item. It just stays the same size and never changes. Did I forget anything? I can't figure it out.

Best Regards,
Roman

Hello,

I have a grid where is use OnRead to get the data. The EditMode is set to Inline. 
I can insert, and delete a row from the grid but I can't edit a row.
I have defined EditorTemplate but it doesn't enter into it.
I'm trying to migrate the solution on the version 3.7.0 of your framework.
Previously I had the version 2.29 of your framework where I didn't got that problem.
Behind the grid I have a DataTable like in this example: https://demos.telerik.com/blazor-ui/grid/data-table

I've read the articles regarding this issue and I also tried the solution on this topic
https://www.telerik.com/forums/grid-with-inline-edit-how-to-add-new-row-and-manage-save-cancel-request-from-code
But it doesn't seams to work for me, the EditorTemplate is not displayed.

I will appreciate if you can help me on this issue.

Thank you in advance,
Cipri

Hello,

I want to provide two modes for editing with the editor.

One full-featured editor with all tools (EditorToolSets.All) and one mode with none or only custom tools and I want to switch between the modes.

So I tried somethink likse this:

private List<IEditorTool> tools { get; set; } = new List<IEditorTool>();

protected override Task OnInitializedAsync()
{
    tools = EditorToolSets.All;
    tools.Add(new CustomTool("MyTool");
}
 
private void SwitchModel(MyMode mode)
{
    if (mode == MyMode.Full)
    {
        tools = EditorToolSets.All;
    }
   
    if (mode == MyMode.None)
    {
        tools = Clear;
    }
}

Hi,

I have a TelerikEditor with additional custom tools:

In the razor-file:

<TelerikEditor @bind-Value="@myContent" Toosl="@tools">
    <EditorCustomTools> 
    @* Custom tools here *@
    </EditorCustomTools>
</TelerikEditor>

in the code behind file:

private List<IEditorTool> tools { get; set; } = new List<IEditorTool>();

protected override Task OnInitializedAsync()
{
    tools = EditorToolSets.All;
    tools.Add(new CustomTool("MyTools");
    return base.OnInitializedAsync();
}

At this point, all works as expected.

But when I navigate to another page in my wasm App and then navigate back to the page with the editor, the custom tools is renderd twice. If I navigate away and back to the page once more, the custom tool is now renderd three times. If I do it again: four times the custom tool ....

I tried:

tools = new();

as first line in OnInitializedAsync, but with the same result.

I think it is a rendering problem. I checked tools.Count at the beginning of OnInitializedAsync and it is alway 0.

Any suggestions? :-)

Hi,

I have set up my model the exact way it is in the demo. My client makes a JSON call to API to populate the scheduler. The post is successful but the get seems to break the scheduler. The error message is below:

Error: System.InvalidCastException: Unable to cast object of type 'System.String' to type 'System.Collections.Generic.IEnumerable`1[System.DateTime]'. at Telerik.Blazor.Components.TelerikScheduler`1.CreateAppointment(TItem dataItem) at Telerik.Blazor.Components.TelerikScheduler`1.ExpandAppointments() at Telerik.Blazor.Components.TelerikScheduler`1.ProcessAppointmentsAsync() at Telerik.Blazor.Components.TelerikScheduler`1.OnParametersSetAsync() at Microsoft.AspNetCore.Components.ComponentBase.CallStateHasChangedOnAsyncCompletion(Task task) at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle)

unsure why I need to cast as the demo it seems to work fine without casting. Is this an issue within the UI control itself?

I'm using version 2.24.0

Thanks

Say I have a report with 13 month column names.

Depending on the date range given to report the columns names could be different.

How do I build the resulting class to hold the data for the gird in this case?

 public class MgtRtp2Result
        {
            public string? TN { get; set; }
            public string? BAN { get; set; }
            public string? Platform { get; set; }

            [DisplayFormat(DataFormatString = "{0:C}")]
            public decimal Col1Amt { get; set; }

            [DisplayFormat(DataFormatString = "{0:C}")]
            public decimal Col2Amt { get; set; }

      }

Col1Amt name in the SQL result coming back could be May2022 for first run but Jun2022 for next run.

Same thing can happen Col2Amt.

Thanks for the help.

I am having an issue with this control.

When testing it I init it from the OnInitialized section and it worked fine.

But in production app It does not get init until after a DDL on the page is chosen from by user.

In this case I keep getting NO Data displayed on the drop down part.

Take the same code and put in the OnInitialized section and the controll is filled in.

How can I get it to work after the ddl is chosen?

Thanks

I have a SP I call that takes 1 or 2 minutes to run.

I am running into the error:

system threading taskcanceledexception a task was canceled

atm the SP takes 1:08 to run.

At 35 seconds, using filters to get less data back, it runs fine!

We have many reports that take a bit to run.

How to I get this task thing to stop killing my app.

I have a TelerikGrid with OnRead set with code that retrieves Paged data via an API.

I store the items + page number + total items etc so that when the user returns they see their previous search.

I tried using OnStateInit, but it only lets me set the page number - not the data items or total results.
