When the page is printed, the Grid is extended down onto multiple sheets of paper. This is because the Grid is large. The issue I am having is that the column headers are not repeating on each printed page. This makes the grid very hard to read. Is there a setting that can force the column headers to print on each printed page?

For Excel export, this depends on: https://feedback.telerik.com/document-processing/1356293-print-titles.
For PDF export, this depends on: https://feedback.telerik.com/blazor/1434269-export-grid-to-pdf.
The filter list item menu defined as follows do not have accessible name. Please provide work around or fix that I can implement.
<TelerikGrid Data="@ViewModel.RouterAndDataLossInformation" TItem="TrafficLossSummary"
Pageable="true"
Sortable="true"
Groupable="false"
FilterMode="Telerik.Blazor.GridFilterMode.FilterRow"
Resizable="true"
Reorderable="true"
Height = "100%">
I need to know which cell the user right clicked on so I can adjust my context menu. I need the cell value, the row model and the field of the column.

I noticed a different behavior when filtering programmatically through the state and when you use the filter UI.
When filtering programmatically the filter is set after the data arrives. I am using a FiltterMenu and the filter icon is colored to indicate there is an applied filter only after the data is filtered. When filtering from the menu, I can the opposite behavior - the filter is set first and then the data is filtered. To me, this seems to be the correct behavior.
Reproduction: https://blazorrepl.telerik.com/wSavwTPd367WqA9r37.
The Grid is supposed to show a loading animation when it detects a data operation that requires more than 600ms to complete. However, if this operation is triggered programmatically through the state and not through the UI, the loading indicator is not shown.
Reproduction: https://blazorrepl.telerik.com/mSuPQpvx498wHvV816.

A possible workaround for the time being is to use a LoaderContainer component when invoking programmatic data operation similar to how the initial loader is shown here: https://demos.telerik.com/blazor-ui/grid/loading-animation.
Please add a feature to export the grid to a PDF file.

ADMIN EDIT
We have made two examples you can use for the time being to get a PDF document from the grid:
- server-side export - getting the grid data request and using some application code to generate the file: https://github.com/telerik/blazor-ui/tree/master/grid/pdf-export-server
- client-side export through Kendo libraries in the browser only: https://github.com/telerik/blazor-ui/tree/master/common/pdf-jpg-export-js

I want to be able to enter numbers and the grid to filter numeric fields too according to those numbers. Enums would be nice too.
**Admin Edit**
The feature request will be researched and evaluated. It contradicts to our datasource filtering logic that relies on the type of the fields. Thus, it is highly possible that we will handle the task through a knowledge base example.
**Admin Edit**
The request targets a hierarchical Grid where some items are expanded - when I edit a parent item and then update it, all the respective detail items collapse.
Please add support for persisting the expanded state of the items.

The feature applies to the other data operations as well (for example, paging, sorting, filtering etc.).
See REPL sample (just use horizontal scroll): https://blazorrepl.telerik.com/wRPvclYX432myApT30.
When switching to Version 4.5 the Grid acts as expected.
https://docs.telerik.com/blazor-ui/components/grid/editing/incell#notes
I am using an EditorTemplate with a method called ChangeHandler(). After clicking in another row everything works fine but if I leave the cell by pressing enter the UpdateHandler gets called more than two times and comparing args.Item with the GridItem doesn't help because the calls are asynchronous.

Admin Edit
With 2.22.0, the InCell editing mode was revamped to provide better user experience and this alters the way it worked. In the common case, there will no longer be double OnUpdate calls (unless explicit application logic invokes them). With 2.23.0, Tab and Enter keys that bubble from editor templates will be handled by the grid like they are handled for the built-in editors.
This means that this issue is, effectively, solved. You can see the Notes section about editor templates to see how you can also handle the OnBlur event to capture mouse clicks outside of the component so that you can save changes and remove the edited item. See the full notes here (the Event Sequence section was heavily revamped for clarity) and here on editor template behavior.
Thus, the previous ides about Save and Cancel methods on the edit context might not be implemented, which will also be one breaking change that we could avoid:
After discussion with the development team, the proposed resolution is to provide a context that provides Save/Cancel operations. The goal is to provide easier configuration for IncellEditing and EditorTemplates and consistent behavior with mouse and keyboard interaction. However, the change will introduce a breaking change in our EditorTemplate, should be researched further and that is why this is logged as a feature request.

I want to add a custom sort comparer but I don't want to perform the whole sorting manually through the OnRead event.
Please allow adding custom expressions that will be applied to the query that the DataSource package does for easier customizations of the data operations.
Looking through the examples I can't find one with SelectionMode="GridSelectionMode.Multiple" and using a RowTemplate.
ADMIN EDIT: This is not a bug in the component, an example of how this can be implemented by the app is available in the comments.
I'm not sure what I should be binding my checkbox to so it accurately reflects selection state.
From the RowTemplate Example adding SelectionMode:
<TelerikGrid Data=@GridData
@bind-SelectedItems="@SelectedItems"
SelectionMode="GridSelectionMode.Multiple" Height="@Height">
<RowTemplate Context="product"> @*Trying to inspect what is generated in the examples I came up with this, but not sure what to bind to checked*@
<td role="gridcell" colspan=0 data-col-index="0">
<span>
<input class="k-checkbox k-grid-checkbox telerik-blazor" type="checkbox" />
</span>
</td><td> <img class="rounded-circle" src="@($"images/{product.ProductId}.jpg")" alt="Alternate Text" /> @product.ProductName </td> <td> @(String.Format("{0:C2}", product.UnitPrice)) </td> </RowTemplate> <GridColumns> <GridColumn Field=@nameof(Product.ProductName) Title="Product Name" /> <GridColumn Field=@nameof(Product.UnitPrice) Title="Unit Price" /> </GridColumns> </TelerikGrid>
I am using Telerik Grid in our project and I have enabled the feature Reorderable="true". At GridColumnMenuSettings I am getting the following options:
Set column position :
- Move Next
- Move Previous
Those options are commonly showing for all columns but I want to disable "Move Next" option for the last column and "Move Previous" option for the first column as these options are not applicable to the corresponding columns.
