Hi Silvia,
Can the column details be discovered at startup time? I'm thinking of
something like this:
IList<string> dynamicColumns = GetCustomerColumns();
DynamicComponent(x => x.AdditionalFields, c =>{
foreach(string col in dynamicColumns)
{
string temp = col; // Avoid any modified closure issues.
c.Map(x => (string)x[temp]);
}
});
