I want to make the scheduler event cells bigger in height. However, I'm not able to achieve it with ItemTemplate nor overriding the css. Is there a way to achieve this?

Also, why my previous question about this have been deleted? If there's no way of achieving that, why don't you just say it's not possible instead of deleting my question?

Right from the start I get following errors in den Dircect Window:

System.ArgumentNullException: Value cannot be null. (Parameter 'nullableType')
   at System.ArgumentNullException.Throw(String paramName)
   at System.Nullable.GetUnderlyingType(Type nullableType)
   at Telerik.Blazor.Common.Filter.FilterOperatorFactory.GetFilterOperatorsForType(Type type, ITelerikStringLocalizer localizer)
   at Telerik.Blazor.Components.Common.BoundColumnBase.ThrowIfInvalidDefaultFilterOperator()
   at Telerik.Blazor.Components.Common.BoundColumnBase.OnParametersSet()
   at Microsoft.AspNetCore.Components.ComponentBase.CallOnParametersSetAsync()
   at Microsoft.AspNetCore.Components.ComponentBase.RunInitAndSetParametersAsync()
   at Telerik.Blazor.Components.Common.ColumnBase.SetParametersAsync(ParameterView parameters)

I can not load any Grid anymore. The error shows:

System.ArgumentNullException

Value cannot be null. (Parameter 'nullableType')

I think it has something to do with "DefaultFilterOperator" but I cannot figure out it myself

With 5.1.1 everything works just fine.

For my use case the logical operator will always be "And" and there is no grouping.  I'd like to hide those buttons to avoid confusing end users. Is that possible?

Hello everyone,

I am experiencing an issue with my Blazor application and am seeking advice or solutions from anyone who might have had the same issue.

When interacting with the Telerik Editor within a Telerik Grid, clicking inside the editor unexpectedly exits the edit mode. This seems to be linked to event propagation issues, where clicking the editor triggers a propagation that causes the grid to exit edit mode.

Error Messages:

When my issue triggers, I also see the following error in the console:

Uncaught TypeError: Cannot read properties of null (reading 'state')
This occurs within the telerik-blazor.js script and seems related to handling state changes or events. 

I already looked trough Troubleshooting but removing all "StateHasChanged" didn't solve the issue.

What I've Tried:

Implemented JavaScript to stop event propagation using event.stopPropagation() within various event handlers (click, mousedown, etc.).
Checked that the event handlers are correctly assigned and that the JavaScript is initialized at the correct life cycle phase in Blazor (OnAfterRenderAsync).
Removed any redundant StateHasChanged() calls as per Telerik's recommendations to prevent unnecessary re-rendering and potential race conditions.

Code:

The Telerikgrid with the Telerikeditor:

<TelerikGrid Data="ProzessSubPosListe"
             EditMode="@GridEditMode.Incell"
             OnUpdate="@UpdateHandlerProzessPos"
             OnDelete="@DeleteHanlderProzessPos"
             Size="@ThemeConstants.Grid.Size.Small"
             PageSize="100"
             Sortable="true"
             Pageable="false"
             Resizable="true"
             >
    <GridColumns>
        <GridColumn Field="@nameof(ProzessPosClass.Nr)" Title="Nr" Width="10%"></GridColumn>
        <GridColumn Field="@nameof(ProzessPosClass.Title)" Title="Thema" Width="20%"></GridColumn>
        <GridColumn Field="@nameof(ProzessPosClass.ProzessContent)" Title="Beschreibung" Width="20%">
            <EditorTemplate Context="dataItem">
                <div @onclick:stopPropagation="true" @onclick:preventDefault="true">
                @{
                    var item = dataItem as ProzessPosClass;
                    <TelerikEditor @bind-Value="@item.ProzessContent" Width="650px" Height="400px" ></TelerikEditor>
                }
                </div>
            </EditorTemplate>
        </GridColumn>
        <GridCommandColumn Context="Journal" Width="100px">
            <GridCommandButton Command="Save" Icon="@("save")" ShowInEdit="true"></GridCommandButton>
            <GridCommandButton Command="Delete" Icon="@("trash")"></GridCommandButton>
            <GridCommandButton Command="Cancel" Icon="@("cancel")" ShowInEdit="true"></GridCommandButton>
        </GridCommandColumn>
    </GridColumns>
    <NoDataTemplate>
        <strong>Kein Prozessschritt vorhanden</strong>
    </NoDataTemplate>
</TelerikGrid>

protected override async Task OnAfterRenderAsync(bool firstRender)
{
    if (firstRender)
    {
        await JSRuntime.InvokeVoidAsync("setupEditorEventHandling");
    }
}

My Javascript inside of _Layout.cshtml trying to resolve the issue:

 <script>
     function setupEditorEventHandling() {
         console.log("Setup editor event handling");
         document.addEventListener('click', function (event) {
             try {
                 var editor = event.target.closest('.k-editor.telerik-blazor');
                 if (editor) {
                     event.stopPropagation();
                 }
             } catch (error) {
                 console.error('Error handling editor click:', error);
             }
         }, true);
     }
 </script>

How the issue looks like:

Has anyone encountered similar issues with event handling in Blazor applications using that setup? 

Any insights or suggestions would be greatly appreciated.

This ComboBox, with filtering and custom values enabled, glitches when typing in the box. At a normal typing speed, I'm seeing that about 10% of keystrokes are skipped, or appear briefly and then disappear.

<TelerikComboBox Data="@_data"
                 @bind-Value="@_value"
                 AllowCustom="true"
                 Filterable="true"
                 FilterOperator="@StringFilterOperator.Contains"
                 Enabled="@Enabled"></TelerikComboBox>
...
List<string> _data = new() { "Lorem", "ipsum", "dolor", "sit", "amet", "consectetur", "adipiscing", "elit" };
string _value { get; set; }

Dropped letters are slightly less frequent with DebounceDelay="0" ; it's worse with more items in the list. It seems to occur if you type more than 3-4 letters per second.

Also, clicking the cursor in the middle of the text and typing can cause the cursor to jump to the end of the input and jumble your letters around.

Hi, recently i got the licese, ive been working with the "Trial version", but when i activate the licese my proyect warns me that some componetn called "InitCart" is no initialized

I'm trying to use TelerikGrid to drag and drop items from subgrid to subgrid (Using another TelerikGrid in the DetailTemplate).  I have gotten it to work well when moving rows around the same grid, but it doesn't work when I try to drag from one grid to another.  The event only fires for the source grid and not the destination grid, whereas the documentation says it should fire for both.

I'm not sure whether I'm doing something wrong or if this function just doesn't work if the two grids don't have the same parent component.

                <TelerikGrid Data=@_items
                             Height=@GetHeightValue()
                             Width=@GetWidthValue()
                             FilterMode="@GridFilterMode.FilterMenu"
                             Pageable=@Pageable
                             PageSize=@(PageSize ?? DefaultPageSize)
                             OnRowClick="@OnRowClick"
                             DetailTemplate="@GetGridDetailContent()"
                             RowDraggable=@RowDraggable
                             OnRowDrop="@((GridRowDropEventArgs<DataType> args) => OnRowDropHandler(args))"
                             @ref=@_grid>
                    <GridSettings>
                        <GridRowDraggableSettings DragClueField="@nameof(DataType.Name)">
                        </GridRowDraggableSettings>
                    </GridSettings>
