In DataGrid, which is using LoadData method, when you filter out all data and nothing found row showing up. In this case if you will try to add new row, it will never show up. This is only happens in nothing found case.

To Reproduce
Steps to reproduce the behavior:

Open page with DataGrid (which is using Inline Editing and LoadData important method)
Apply a filter on one of the columns so nothing will be found
Try to add new record (row)
See that new row didn't appear

Expected behavior
New row should show up instead of nothing found

Once Again
This is not happens when only Data is using. ONLY when LoadData is using.

Example which causing that bug

<RadzenDataGrid
    @ref="@Grid"
    Style="height: calc(100vh - 149px)"
    AllowFiltering="true"
    FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive"
    AllowColumnResize="true"
    FilterMode="FilterMode.Advanced"
    AllowPaging="true"
    PageSizeOptions="@PageSizeOptions"
    PageSize="@DefaultPageSize"
    AllowSorting="true"
    IsLoading="@IsLoading"
    LoadData="@LoadData"
    Data="@Data"
    Count="@Count"
    RowCreate="@AddRow"
    RowUpdate="@UpdateRow"
    TItem="DataModel"
    EditMode="DataGridEditMode.Multiple"
    LogicalFilterOperator="LogicalFilterOperator.And">

Hey @s-dezign,
There is indeed problem with InsertRow() method when the DataGrid is bound using LoadData. The only workaround we can offer is to insert new item in the collection assigned to Data property instead. You can check also the code generated by Radzen inline edit page template for reference.

@enchev do you have that code generated by Radzen by any chance ?

@enchev it is still doesn't work. I did add new item into Data instead of InsertRow(), but first it is causing issue when you cancel Editing new row and second it doesn't resolve issue when No records to display message new row is not appear.

This appears to be an ongoing issue, and it affects the scaffolded code from the current version of Blazor Studio. Is there any documented way to resolve this?

I have encountered this issue as well.
I am using the following workaround: before calling InsertRow() I set ShowEmptyMessage to false and it seems to bypass the problem.
