Pivot Grid Module - Support the Data View mode

created 9 years ago

Hi,

In the first verions that supported DataView Mode, it also supported PivotGrids. We implemented and tested this on large databases, and it seemed to really improve performance. In later versions, support voor DataView with PivotGrids was removed.

Is this correct and if yes, is there a way to re-enable it or plans to support it again in the future ?

Greetings
Xavier

We have implemented the functionality described in this ticket. It will be included in our next update(s).

Please check back and leave a comment to this response to let us know whether or not this solution addresses your concerns.

Additional information:

Pivot Grid List Editors (PivotGridListEditor and ASPxPivotGridListEditor) now support the Data View mode.

    Hello Xavier,

    The DataView mode was available in PivotGrid List Editors previously by mistake, which was corrected in v14.2. In fact, we have not yet profoundly tested these scenarios and there were different side effects. See also the corresponding note in the product documentation at List View Data Access Modes:
    "Currently, the Data View mode is supported by two built-in List Editors - the GridListEditor, used by default in Windows Forms applications, and the ASPxGridListEditor, used by default in ASP.NET Web applications."

    If this functionality met your business needs previously, you are free to enable and continue using it at your own risk by creating a descendant of the DevExpress.ExpressApp.PivotGrid.Win.PivotGridListEditor class and overriding the SupportDataAcessMose method as shown below:

    C#
    public override Boolean SupportsDataAccessMode(CollectionSourceDataAccessMode dataAccessMode) { return (dataAccessMode == CollectionSourceDataAccessMode.Client) || (dataAccessMode == CollectionSourceDataAccessMode.DataView); }

    See the How to: Implement a Custom WinForms List Editor article for more details.
    Our team will take your input into account and will consider allowing this functionality once we finalize necessary R&D, though I cannot give you an exact time frame regarding this.
