Hello,
I was wondering if it was possible to adjust the Store to send the ServerMapping when RemoteSort is enabled? If this is not possible, and I can imagine there are some scenarios where you would want to pass back the Name instead of the ServerMapping ... would it be possible to add a SortName ?
Thanks for the help both of you.
Cheers,
Timothy
Hi,
ServerMapping property is not serialized therefore is not accessable on client side. The store can you use only existing field's names therefore additinal names can't be used (also if we will use custom names the grid can't determine on what field was performed the sort operation)
It can be implemented but it is required big changes in store/grid/gridview js classes
OK, with the below example is there anyway I can return "Department.Name" to the Store1_RefreshData function instead of "Department" ?
I don't want to start getting into case statements to swap out real meaning on the server-side.
Example:

}
public class Employee
{
public int ID { get; set; }
public string Name { get; set; }
public string Surname { get; set; }
public Department Department { get; set; }
public static List<Employee> GetAll()
{
return new List<Employee>
{
new Employee
{
ID = 1,
Name = "Nancy",
Surname = "Davolio",
Department = Department.GetAll()[0]
},
new Employee
{
ID = 2,
Name = "Andrew",
Surname = "Fuller",
Department = Department.GetAll()[2]
}
};
}
}
public class Department
{
public int ID { get; set; }
public string Name { get; set; }
public static List<Department> GetAll()
{
return new List<Department>
{
new Department {ID = 1, Name = "Department A"},
new Department {ID = 2, Name = "Department B"},
new Department {ID = 3, Name = "Department C"}
};
}

Hi,
You can write function which can juxtapose Name <-> ServerMapping
Then just use that function in Store1_RefreshDataCode:public string GetSortName(string name)
{
foreach (RecordField field in strStore.Reader.Reader.Fields)
{
if(field.Name == name)
{
return string.IsNullOrEmpty(field.ServerMapping) ? field.Name : field.ServerMapping;
}
}
return name;
}
Code:string sortName = this.GetSortName(e.Sort);
Thanks, I will use the example you provided. I'm wondering tho, to make it more intuitive for other users would it be possible to attach the RecordField in the StoreRefreshDataEventArgs for ease of use?
Sorry for being a pest :)
Cheers,
Timothy
I implented this in version .8 and it worked perfectly. Now that i'm refactoring to 1.0, this no longer works. If i set the ServerMapping property it will throw an error:

Hi,
Please create separate topic with test sample which demonstrates the problem. Just this topic is solved already
