AX7 : DISPLAY METHOD ON TABLE EXTENSION
Views (53)
On AX7 we don’t have the option to create methods on table extension, so we should use the extension class to do that. The example below will show how to create a display method on the table extension class and use on a form extension.
First create your table extension class and your display method following the example below:
public
static
class
MyCustTable_Extension
{
[SysClientCacheDataMethodAttribute(
true
)]
// optional
public
static
display Name myDisplayName(CustTable _this)
{
return
_this.nameAlias() +
"myDisplayName"
;
}
}
To use your display method on the form, create your new field on the form extension and use the property as below:

To cache your display method on the form set on the field the property “Cache Data Method” = yes if you don’t want to use the Attribute above.
