I need to bind a complex object to telerik grid field, i read the article

https://docs.telerik.com/blazor-ui/knowledge-base/grid-bind-navigation-property-complex-object

but it not explain if i can bind an indexed property.

For example i need this bind:

<GridColumn Field="Property.NestedProperty[0].Value" />

but it seem not working.

Can be binded indexed properties?

Thanks

Is there a way to do this? Right now, if you have too many, they just run off the screen.

Thanks... Ed

Hi,

I'm using onread to fetch odata from a backend system.

I also have signalR setup that listens for changes on the objects in the list.

I would like to be able to update a single property of an object when an signalr event is received. I'm aware of the Rebind() method, but this forces the entire list to be loaded again. Since i have a lot of events firing and multiple clients, it would make more sense if i could get the objects from the gridref.Data property and update only the affected record and property.

Think of this as a grid as a stock-ticker overview, where values are updated very frequently.

Do we have a solution for this?

Well large for me. :) 360K+ records to excel.

Works on the Dev PC but when published to web server it does nothing. No errors either.

I tried setting MaximumReceiveMessageSize but that didnt seem to do much.

Anyone any ideas on fixing this?

Thanks

Hello,

Blazor WebApp here.

I try TelerikAutoComplete inside a TelerikGird without success.   Do you provide a complete example so I can use it? 

How I can get the current field value as searchTerm to send it to the API?

<GridColumn OnCellRender="@((GridCellRenderEventArgs args) => OnCellInfosEmplacementDestinationRenderHandler(args, "emplacementDescriptionCompleteFr"))" Field=@nameof(treltlkpEmplacementViewModel.emplacementDescriptionCompleteFr) Title="Description FRANÇAISE" TextAlign="@ColumnTextAlign.Left" >
        <Template>
            <TelerikAutoComplete TItem="@String"
                Id="TitreFr"
                ScrollMode="@DropDownScrollMode.Scrollable"
                ItemHeight="30"
                PageSize="10"
                OnRead="@OnReadAutoCompleteEmplacementDescriptionCompleteFr"
                @bind-Value="@((context as treltlkpEmplacementViewModel).emplacementDescriptionCompleteFr)"
                FillMode="@Telerik.Blazor.ThemeConstants.AutoComplete.FillMode.Solid">
                <AutoCompleteSettings>
                    <AutoCompletePopupSettings Height="100px" />
                </AutoCompleteSettings>
            </TelerikAutoComplete>
        </Template>
</GridColumn>

    async Task OnReadAutoCompleteEmplacementDescriptionCompleteFr(AutoCompleteReadEventArgs args)
    {
        treltlkpEmplacementViewModel item = (treltlkpEmplacementViewModel)args.Data;

        if (!string.IsNullOrWhiteSpace(?????????))
        {
            await ObtenirEmplacementDescriptionCompleteAutoCompleteAsync(args, SafetyStudioSolution.Shared.Constants.cultureNameFr, ?????????);
        }
    }

Thank you for your fast answer.

I have a need to be able to click on a cell and then capture the value in that cell in codebehind.

How can I do that?

I tried to play around with Column Template but I am getting no where. :(

Need a GridCell_OnClick event so I can grab the cell value the Row tis on and the Column tis in.

Thanks

Hi:

I want to create a blazor crud using DataSource with entity framework. Do you have a sample code?

I found a lot of samples to get data, filter, etc., but not for crud operations using Data Source.

Thanks in advance.

Hi,

I'm looking for a way to reduce group-cell width for the whole grid. I found the css class ( ) 

<td class="k-table-td k-group-cell" role="gridcell"></td>

But i can' figure out how to do .  Here's a picture

Can u help me ?

Hello! I want to import .json files from my local machine using FileSelect:

<TelerikFileSelect AllowedExtensions = "@AllowedExtensions" MaxFileSize="@MaxFileSize" OnSelect = "@OnFileSelectHandlerTest"></TelerikFileSelect>

The maximum file size is set to 4MB and the OnSelect function is as defined below, which is pretty much the example given at Blazor FileSelect - Events - Telerik UI for Blazor:

    async Task OnFileSelectHandler(FileSelectEventArgs args)
    {
        foreach (var file in args.Files)
        {
            var byteArray = new byte[file.Size];
            await using MemoryStream ms = new MemoryStream(byteArray);
            await file.Stream.CopyToAsync(ms);
        }
    }

The method works fine for very small documents, below +- 26KB. Above this threshold, the app warns that it is attempting to reconnect to server and, after a couple of seconds, no document appears which suggests that the application gets stuck awaiting the CopyToAsync. The rest of the application (outside the FileSelect component) still works, but I can no longer add new files or remove the ones already selected. Has anyone been experiencing this problem and managed to solve it? (the same happens if I first create a local file and copy asynchronously into it)

Thank you
