控制数据源中某一列是否允许编辑 FormDataObject allowEdit

void updateDesign()
{
    FormDataObject  fldItemName;

    // Only allow the item name to be modified if it's a service item
    //
    // Notice that this effects the controls both on the grid, and on the general tab.
    fldItemName = inventTable_DS.object(FieldNum(InventTable,ItemName));
    fldItemName.allowEdit(inventTable.ItemType == ItemType::Service);
}

 

 

//将所有Field禁止编辑

To prevent editing code when you add fields to the table, call the fieldproperties using the dictionary classes:

void SetFieldsAllowEdit()   // 这是数据源中的方法
{
    FormDataObject  fldItemName;
    boolean         allowEdit = false; //This would set according to some criteria
    SysDictTable    dictTable = new SysDictTable(this.table());
    FieldId         currentFieldId;
    ;
    for (currentFieldId = dictTable.fieldNext(0); currentFieldId; currentFieldId = dictTable.fieldNext(currentFieldId))
    {
        fldItemName = this.object(currentFieldId);
        if (fldItemName)
            fldItemName.allowEdit(allowEdit);
    }
}
