Chain of Command(COC) & Event Handler

We can write the COC’s for individual objects by specifying the object name in the [ExtensionOf(ObjectName)] on the class header.

 

1)  For Class COC we use 

[ExtensionOf(classStr(ClassName))]

 

2)  For Form COC we use 

[ExtensionOf(formStr(FormName))]

 

3) For FormControl COC we use [ExtensionOf(formControlStr(FormName,FormControlName))]

 

4) For FormDataSource COC we use [ExtensionOf(formDatasourceStr(FormName,FormDSName))]

 

5) For FormDataFieldStr COC we

Use [ExtensionOf(formDataFieldStr(FormName,FormDSName,Field))]

 

6) For Table COC we use 

[ExtensionOf(tableStr(TableName))]

 

7) For Data Entity COC we use 

[ExtensionOf(tableStr(DataEntityName))]

COC for Form Data Field
