Hello! I've been having this issue with the DataGrid. When I press sort, the Sort-callback calls on the backend to fetch new data that is sorted depending on the column that is clicked. But for some reason, after the data is fetched, the sorting on the column resets. This means that if I click on the column once, it sets descending sorting, fetches the data, and then the descending sorting dissapears on the column. So if i click again, it will just set descending again.
<RadzenDataGrid TItem="SearchDocumentResponseItem"
Data="@_documents"
AllowFiltering="false"
AllowSorting="true"
Sort="GetSortedItems"
GridLines="DataGridGridLines.Horizontal"
AllowAlternatingRows="false"
Responsive="true"
CellClick="@OpenDetails"
IsLoading="_isLoading">
<Columns>
<RadzenDataGridColumn Title="Title" Property="@nameof(SearchDocumentResponseItem.Name)"
CssClass="table-title-column"
OrderIndex="1">
<Template Context="document">
<InternalText="@document.Name" />
</Template>
</RadzenDataGridColumn>
In the GetSortedItems I do an API-call that fetches new documents and sets the _document-variable.
When I click around in the example page, it works like expected. But I also don't see a difference between the examples and mine.
If it could be relevant, I'm running an older version of Radzen (4.xxx), I tried upgrading to 5.10 but the same behaviour was there so I guessed it's not about that.
Edit: After toying around with it a bit, I notice that this behaviour dissapears when I instead of doing _documents = results.Data.ToList()
I do
_documents.Clear();
_documents.AddRange(results.Data.ToList())
But this causes its own issues of sometimes the grid doesn't update after the list changed.
