I have an AggregateDescriptions like this

<DataProviders:LocalDataSourceProvider.AggregateDescriptions>
     <Core:PropertyAggregateDescription PropertyName="Prize" CustomName="Count" AggregateFunction="Count" />
     <Core:PropertyAggregateDescription PropertyName="Prize" CustomName="Sum" AggregateFunction="Sum" />
     <Core:PropertyAggregateDescription PropertyName="Prize" CustomName="Max" AggregateFunction="Max" />
     <Core:PropertyAggregateDescription PropertyName="Prize" CustomName="Min" AggregateFunction="Min" />
</DataProviders:LocalDataSourceProvider.AggregateDescriptions>

When using them in the RadPivotFieldList in the 'Value' -cell, they all show up as "Prize".
Is it possible to set a DisplayName or something like that?

And what about formatting money? Is it possible to set the decimals?

Hello,

With the current release you are not able to change the property name in the 'Value' cell, but this will be available for our official release. Sorry for the caused inconvenience.
With the CTP release string formatting of the cells is not possible, but if you download one of our latest internal builds you'll be able to use many different string formats (we've added this functionality after the CTP release). Here's a simple example for some of the formats:
LocalDataSourceProvider dataProvider = this.Resources["DataProvider"] as LocalDataSourceProvider;
var desc = dataProvider.AggregateDescriptions[0] as PropertyAggregateDescription;
 
//different string formats (choose one of the below, remove the others)
desc.StringFormat = ""; // 1234.45 -> 1234.45
desc.StringFormat = "0.000"; // 1234.5678 -> 1234.567
desc.StringFormat = "######"//1234.5678 -> 1235
desc.StringFormat = "$ 0.00"//1234.5678  -> $ 1234.57
desc.StringFormat = "0.0 %"//1234.5678 -> 1234.6 %
desc.StringFormat = "#.# °"; //1234.5678 -> 1234.6 °
desc.StringFormat = "C"//123.456 -> $123.46
 
dataProvider.Refresh();

In fact you'll be able to use most of the string formats described here. Hopefully this helps.

Thank you for choosing RadPivotGrid. Don't hesitate to contact us if you have any suggestions or concerns.

Hi

I am trying to adjust a formatting before exporting the PivotGrid as suggested above :-

dataProvider.AggregateDescriptions[0].StringFormat = "";
dataProvider.Refresh();
_exportModel = PivotGrid.GenerateExport();

However after changing the format the exportGrid rowCount and colCount =0. Do you know what would cause this ? Else is there a way to export the raw data without the style formatting?

Regards
Ryan

Hi Ryan,

Thank you for contacting us.

The reason for the explained behavior is that the Pivot hasn't finished refreshing the layout when the GenerateExport() method is called (it needs some more time). The Cells haven't been generated yet and this is why the rowCount and colCount properties are zero. What I can suggest you in order to achieve the desired would be to apply the desired StringFormat right before the SaveFileDialog is shown - this way the string will be applied, the Pivot refreshed and exported correctly.

Hope this will work for you.

Regards,
