Blazor - The Page Size = All option is not removed when DataAccessMode = Server in DxGridListEditor

Blazor - Root List Views select all records in Server mode

[DevExpress Support Team: CLONED FROM T936581: Blazor - Performance - LookupPropertyEditor loads all records from its data source when a DetailView is shown]

Hi Guys,

i just did another blazor test after some time now - you said above "Root List Views have a pager and load only objects from the current page (e.g., top 20 records)."

in fact that does not work - we have server mode enabled - but root listviews also do an select * from table ?

Update:
Just found in DevEx Sourcecode that GridListEditor only Supports Client and Queryable DataAccessModes - so is the above statement wrong?

Hello Martin,

Server mode is not supported in Blazor UI. However, starting with v20.2.5 Blazor supports the Queryable mode that works similarly. It selects data partially depending on the current Data Grid page or the lookup editor's scroll position. To enable the Queryable mode in root and lookup List Views, use the Options -> DataAccessMode model property.
Starting with v20.2.5, the Client mode loads all records, as in WinForms and ASP.NET WebForms. Soon we will update our documentation to describe differences between these modes in greater detail.

      Hello Martin,

      We did not implement sorting and grouping by such columns yet. We are going to implement this for the Client mode soon - our developers are already working on this. We will likely be able to implement this in Server (or Queryable) mode later (in v21.2), when a new Blazor Grid is ready.

        thx Anaton - was just a bit confusion since you said initially it should work in client mode :)

          Hello,

          In v22.1, DxGridListEditor is the main List Editor. This editor supports Client and Server Data Access modes with the features described above. You can refer to the following article to see how to enable DxGridListEditor in older versions: Enable the DxGridListEditor.

          Thanks,
          Stanislav
