Which MVVM the staff use

Hi all.

I was wondering which MVVM framework or ddl are using, if any, to build the samples?

Beside the facts I cannot solve the annoyng DataVirtualization of sfDataGrid.
Same model and ViewModel ecc.

MS DATAGRID under 3 seconds, with good internet connection under 2 seconds.
sfDataGrid 16 secs! there is a problem :). So I am asking the MVVM to recreate the same conditions of the samples.

Hi Arn,

Thank you for contacting Syncfusion support.

We are not able to understand your clearly and we need more information on this. Based on your update content, could you please confirm whether you are facing performance problem while fetching the data’s from server or you would like to have SfDataGrid sample with MVVM pattern?

If you are facing performance problem with DataVirtualization, could you please update the number of columns and records  you are using in SfDataGrid? Could you please confirm whether you are using any Cellstyles or applying style using styleselectors? And please confirm whether you are using Triggers to set cell value in your application?

Normally if we use ColumnSizer as “Auto” in SfDataGrid, column width will be calculated based on cell value of particular column and header text. If the cell value length is greater than header text length, cell value length will be set to width of column or else header text length will be set. This is the behavior of our Auto ColumnSizer in SfDataGrid. Hence if you loading more number of records with ColumnSizer as ‘Auto’ in SfDataGrid, it will take some time to load due to the behavior of ColumnSizer. So we request you to use other than Auto ColumnSizer in your application.

Please let us know if you require further assistance on this.

Hi Ashok
More simple.
The majority of your samples follow the MVVM paradigm.
I was asking: WHICH MVVM do You use?
To make consistency from my research and Your way of works.
