Update previous saved schemas with columns added on an SfDataGrid

[Bill]

If there's an SFDataGrid for which the user has saved several schemas on date X, and I (as the developer) add a column on the grid on a date after date X (for example, the schemas were saved on March 3 and I added the grid column today, March 5)... 

Is it possible to update the previously saved schema with the new grid columns? Not serializing the columns is not an option because I have given end users the feature of setting width, visibility and header text of columns in the schemas.

Hi Bill,

Thank you for contacting Syncfusion support.

Your requirement can be achieved by the defining unbound column in SfDataGrid and give a value as increment of date in SfDataGrid.QueryUnboundColumnValue event. Please refer the below code snippet, 

 

this.sfDataGrid1.QueryUnboundColumnValue += SfDataGrid1_QueryUnboundColumnValue; 

 

private void SfDataGrid1_QueryUnboundColumnValue(object sender, GridUnboundColumnEventsArgs e) 

        {             

 

                var date = (e.Record as OrderInfo).Date; 

 

                e.Value = date.AddDays(2).ToString("MM/dd/yyyy");                 

             

        }
