Question

我有以下数据（示例）：

tblModel
Mod_ID  Mod_Num  Mod_Desc
1       0001     Model01
2       0002     Model02

tblArticle
Art_ID  Art_Num  Art_Desc
1       001      Article X
2       002      Article Y
3       003      Article Z
4       004      Article K

tblOperation
Op_ID  Op_Num  Op_Desc
1      01      Gluing
2      02      Sewing
3      03      Stitching

tblMaterial
Mat_ID  Mat_Num  Mat_Desc
1       B001     Blue
2       R001     Red 
3       K001     Black

数据结构如下：

tblModelArticle
MA_ID  Mod_ID  Art_ID  MA_Description
1      1       1       Model01 - Article X
2      1       2       Model01 - Article Y
3      2       3       Model02 - Article Z
4      2       4       Model02 - Article K

tblModelOperation
MO_ID  Mod_ID  Op_ID  MO_Description
1      1       1      Model01 - Op Gluing
2      1       2      Model01 - Op Sewing
3      1       3      Model01 - Op Stitching
4      2       1      Model02 - Op Gluing
5      2       3      Model02 - Op Stitching

tblArticleOperationMaterial
AOM_ID  MA_ID  MO_ID  Mat_ID  AOM_Description
1       1      3      1       Model01 - Article X - Operation Stitching - Material Blue
2       2      3      2       Model01 - Article Y - Operation Stitching - Material Red
3       3      5      2       Model02 - Article Z - Operation Stitching - Material Red
4       4      5      3       Model02 - Article K - Operation Stitching - Material Black   

我的问题是：如何在tblArticleOperationMaterial限制中创建一个ComboBox下拉列表？也就是说，一旦我例如选择“MA_ID”为1，我希望能够仅选择1,2,3作为MO_ID。例如，如果输入了“MA_ID”2值，则MO_ID dropbox combox框将仅提供4和5的选项作为MO_ID。
