Editing custom property/column

Question

User923737044 posted

In a given table I have a foreign key column called Role (the type of this column is Role, which is the name of referenced table). Because it needs to be displayed in a specific way, I have "replaced" the Role column with a custom property called RoleWithDefault (see below). I am perfectly able to display the contents of this property (by creating my own FieldTemplate) but I am not sure how to create a FieldTemplate for editing. The setter of RoleWithDefault is simply setting the Role property based on a string value to be selected by the user. Can anyone point me in the right direction?

public class MyClass
{
       public Role RoleWithDefault
        {
                // some get and set
        }
}

public class MyClassMetadata
{

    [ScaffoldColumn(true)]
    [DisplayName("Role")]
    public object RoleWithDefault { get; set; }

    [ScaffoldColumn(false)]
    public object Role { get; set; }

}

Hello：）

How to select? From a Dropdownlist Or from somewhere else, a querystring's past value?

Thx again

Hi,

I solved it by having two columns/properties and hiding the custom column (RoleWithDefault) when in edit/insert mode and hiding the original column (Role) when in read mode. In this way, RoleWithDefault can be used to display the column contents in a custom way, while the user selects entities from the original column when inserting/editing the parent entity. Hiding of columns is quite easy to implement: http://csharpbits.notaclue.net/2010/02/new-way-to-do-column-generation-in.html
