The value type. |
#Returns
Type | Description |
---|---|
MVCx |
The grid view column. |
#Remarks
The following example illustrates how to use model-based properties and lambda expressions to create cell bands:
settings.Columns.Add(m => m.CustomerAddress, c => {
c.Columns.Add(m => m.Country);
c.Columns.Add(m => m.City);
c.Columns.Add(m => m.Street);
});
or …
var cAdress = settings.Columns.Add(m => m.CustomerAddress, c => { c.Caption = "Address"; });
cAdress.Columns.Add(m => m.CustomerAddress.Country);
cAdress.Columns.Add(m => m.CustomerAddress.City);
cAdress.Columns.Add(m => m.CustomerAddress.Street);
… if your model class contains complex properties and you rely on complex properties’ types while using the Columns.Add method:
public class Customer {
public Address CustomerAddress { get; set; }
}
public class Address {
public string Country { get; set; }
public string City { get; set; }
public string Street { get; set; }
}
