selMedel.getSelected().data in code declaration block

[Aod47]

Hi everyone,

How to use this command (javascript) in code declaration block (c#).

GridPanel1.selModel.getSelected().data.fieldname;

I found another command

((Ext.Net.RowSelectionModel)(this.GridPanel1.SelectionModel.Primary)).SelectedRow.RecordID;

that return only RecordID but I need a value from field.

Thank for advance.
