Useful COC syntax
1. Form level
2. Form Datasource level
3. Form DataField level
4. Form Control level
Form level CoC:
When extending a form, use formStr(<FormName>)
Get Buffers:
FormRun formRun = this as FormRun;
FormDataSource dataSource_ds = formRun.datasource(FormDatasourceStr(FormName,DatasourceName));
TableName tableName = dataSource_ds.Cursor();
FormControl formControl = formRun.design().ControlName(FormControlStr(FormName,ControlName));
Example:
[ExtensionOf(formStr(SalesTable))]
final class KSSalesTableFrm_Extension
{
public int active()
{
FormRun formRun = this as FormRun;
//get any datasource from the base form
FormDataSource salesLine_ds = formRun.datasource(FormDatasourceStr(SalesTable,SalesLine));
SalesLine salesLine = salesLine_ds.Cursor();
//get any formcontrol from the base form
FormControl itemName= formRun.design().ControlName(FormControlStr(SalesTable, itemName));
//business Logic
return next active();
}
}
2. Form Datasource level CoC:
When extending a form Datasource, use formDataSourceStr(<FormName>, <DataSourceName>)Example:
[ExtensionOf(formDatasourceStr(SalesTable, SalesLine))]
final class KSSalesTableFrm_SalesLineDS_Extension
{
public void executeQuery()
{
next executeQuery();
FormDataSource formDS = this; FormComboBoxControl comboBoxControl;
//get form datasource
SalesLine salesLineLocal = this.cursor();
//get any other datasource from the base form
FormDataSource inventDim_ds = formDS.formRun().dataSource(formDataSourceStr(SalesTable, InventDim));
InventDim inventDim = inventDim_ds.cursor();
//get any formcontrol from the base form
comboBoxControl = formDS.formRun().design().controlName(formControlStr(SalesTable, SalesTable_SalesTypeGrid));
//business logic
}
}
3. Form Datafield level CoC:
When extending a form Datasource Field, use formDataFieldStr(<FormName>, <DataSourceName>, <DataFieldName>)
Example:
[ExtensionOf(formDataFieldStr(SalesTable, SalesLine, BarCode))]
final class KSSalesTableFrm_SalesLineDS_BarCodeDF_Extension
{
public void modified()
{
next modified();
FormDataObject barCode_do = any2Object(this) as FormDataObject;
FormComboBoxControl comboBoxControl;
//get form datasource
FormDataSource salesLine_ds = barCode_do.datasource();
SalesLine salesLine = salesLine_ds.cursor();
//get any other datasource from the base form
InventDim inventDim = salesLine_ds.formRun().dataSource(formDataSourceStr(SalesTable, InventDim)).cursor();
//get any formcontrol from the base form
comboBoxControl = salesLine_ds.formRun().design().controlName(formControlStr(SalesTable, SalesTable_SalesTypeGrid));
//business logic
}
}
4. Form DataControl level CoC:
When extending a form DataControl Field, use formDataControlStr(<FormName>, <ControlName>)
Example:
[ExtensionOf(formControlStr(SalesTable, PrintMgmt))]
final class KSSalesTableFrm_PrintMgmtCtl_Extension
{
public void clicked()
{
FormControl buttonControl = any2Object(this) as FormControl;
FormRun formRun = buttonControl.formRun();
InventDim inventDim
FormComboBoxControl formComboBoxControl;
//get any datasource from the base form
inventDim = formRun.dataSource(formDataSourceStr(SalesTable, InventDim)).cursor();
//get any formcontrol from the base form
formComboBoxControl = formRun.design().controlName(formControlStr(SalesTable, SalesTable_SalesTypeGrid));
next clicked();
//business logic
}
}
