Has anyone else had a problem with removing files using TelerikUpload?  Upload works fine, but when attempting to remove it hits the Remove method, but the files parameter is null.  I have tried changing the parameter type from string to string[], IFormFile and IEnumerable<IFormFile>.  I've tried changing the parameter name (and corresponding RemoveField), and nothing makes any difference.  I can add a second, custom parameter, and that works ok.  I just can't get a value for files.

Selected markup/code:

                        <TelerikUpload SaveUrl="@(AddDocumentApi())"
                                   Multiple="true"
                                   RemoveUrl="@(RemoveDocumentApi())"
                                   OnUpload="OnUploadHandler"
                                   OnRemove="OnRemoveHandler"
                                   OnSuccess="OnSuccessHandler"
                                   WithCredentials="true"
                                   AllowedExtensions="@AllowedExtensions" />

        public string RemoveDocumentApi() => $"{AddDocumentApiBase}/deletedocument";

        [HttpPost("deletedocument")]
        public async Task<IActionResult> DeleteDocument(string files)
        {
             // Hits a breakpoint here but files is null
            return new EmptyResult();
        }

I have 5 columns but only want to show two of them in reading mode.

When create or update I would like a pop-up edit showing all of the fields.

How do I accomplished this?

I can't find a way to customize the GridCheckboxColumn element.

GridColumn have a Template element but seem not applicable to GridCheckboxColumn.

My goal is to add a clickable icon next to selection check in the header.

How to solve?

Thanks

Hi, i use a TelerikGrid component and i would like to change the UI on grid selection change, so i have:

<TelerikGrid @ref="Grid" ... />

...

@if (Grid?.SelectedItems.Count() > 0)

{

<span>There are items selected!</span>

}

but the message is never displayed even when i select rows on grid.

I noted who if i bind the event SelectedItemsChanged then the SelectedItems property is updated correctly, and the message is diplayed:

<TelerikGrid @ref="Grid" SelectedItemsChanged="@OnSelectedItemsChanged" ... />

...

@if (Grid?.SelectedItems.Count() > 0)

{

<span>There are items selected!</span>

}

Why i need to bind SelectedItemsChanged event even if don't use it?

Thanks

Is there a way to add some delay to the TelerikTooltip component show event? I would like to force the user to hover in the element for a couple of seconds before he can see the tooltip.

Thanks,

Hi,

I have a WPF app that uses Telerik controls and Telerik charting.  This WPF app is now being re-written using Blazor WebAssembly using Telerik Blazor controls and Telerik Blazor charting.  Some of the existing WPF charts have custom context menus that allow users to toggle between displaying the charts with values or displaying the values as percentages.

It seems that the WPF RadChart control supports different format expressions:

https://docs.telerik.com/devtools/wpf/controls/radchart/features/format-expressions

The toggling is achieved by changing the series item label formats e.g.

    Private Sub PercentagesContextItem_Checked(sender As System.Object, e As System.Windows.RoutedEventArgs)
        For Each objMapping In RadChart1.SeriesMappings
            objMapping.SeriesDefinition.ItemLabelFormat = "#STPERCENT{P0}"
        Next
    End Sub

    Private Sub PercentagesContextItem_Unchecked(sender As System.Object, e As System.Windows.RoutedEventArgs)
        Dim strCurrencyMajorSymbol As String = WebContext.Current.User.CurrencyMajorSymbol
        For Each objMapping In RadChart1.SeriesMappings
            objMapping.SeriesDefinition.ItemLabelFormat = strCurrencyMajorSymbol & "#DATAITEM.ValueY{###,###,##0.00}"
        Next
    End Sub

Is it possible to achieve this in Blazor WebAssembly using the Telerik Blazor charting controls and if so, how?

Hi

When the user filters the grid component , I need an event to read new data (base on filter data) from web Api

thank you

Hi, what is the reason when TelerikTextArea with Autosize=true gets height 0px? I have component containing TelerikTextArea with autosize=true. Using this component directly in Page, TelerikTextArea appears OK (height in style gets correct px value) but using within another component it gets 0px. TelerikTextArea is disabled in this case but when enabled, the same issue (however, after any change/keypress, height gets correct).

Best regards

Konrad

Hi,

I have a grid and sometimes at random intervals I get an error "System.InvalidOperationException: TelerikValidationComponent requires a cascading parameter of type EditContext. You can use Telerik.Blazor.Components.TelerikValidationTooltip`1[System.Object] inside a EditForm or TelerikForm".

This is during an edit/update of values.

I use blazor server side
