Deserialization summary with custom aggregation


Dear,

I have a problem deserializing an SfDataGrid.

I have summarized columns in groupings that use custom aggregators. The problem occurs when from the first time I use deserialization on a datagrid, aggregation stops working, but only custom ones.

How should I proceed?

<syncfusion:GridSummaryColumn 
Name="GSITCONT"
CustomAggregate="{StaticResource stringAggregator}"
  Format="'{Distinct}'"
MappingName="SITCONT"
SummaryType="Custom" 
/>

Before deserializing:



After deserializing:

Resolved by ignoring the summarized fields.

var serializationOptions = new SerializationOptions()
            {
                SerializeCaptionSummary = false,
                SerializeGroupSummaries = false,
                SerializeTableSummaries = false,
                SerializeDetailsViewDefinition = false,
                SerializeUnBoundRows = false,
                SerializeStackedHeaders = false
            };


var deserializationOptions = new DeserializationOptions()
            {
                DeserializeGroupSummaries = false,
                DeserializeCaptionSummary = false,
                DeserializeTableSummaries = false,
                DeserializeDetailsViewDefinition = false,
                DeserializeUnBoundRows = false,
                DeserializeStackedHeaders = false
            };

Hi Thiago, 
 
Thanks for the update. 
 
We are glad to know that the reported problem has been resolved at your end. By default custom summaries is not support the Serialization and Deserialization. So when you Serialize and Deserialize the SfDataGrid, you have to disable the Serialization and Deserialization option for that corresponding summaries. 
 
Please let us know if you have any further queries on this. We are happy to help you. 
 
Regards,
