dataGridMediaFile.DataMember ="CateGory2MediaFile";
dataGridMaker.DataSource = DataSetSoundLocation.Tables["CateGory"];
dataGridMaker.DataMember ="CateGory2MediaFile.MediaFile2Maker";

dataGridCateGory.DataSource = DataSetSoundLocation.Tables["CateGory"];
dataGridMediaFile.DataSource = DataSetSoundLocation.Tables["CateGory"];
dataGridMediaFile.DataMember ="CateGory2MediaFile";
dataGridMaker.DataSource = DataSetSoundLocation.Tables["CateGory"];
dataGridMaker.DataMember ="CateGory2MediaFile.MediaFile2Maker";

Answer 3

//绑定dataGrid    你绑定的时候错了
dataGridCateGory.SetDataBinding(DataSetSoundLocation,"CateGory");
dataGridMediaFile.SetDataBinding(DataSetSoundLocation,"CateGory.CateGory2MediaFile");
dataGridMaker.SetDataBinding(DataSetSoundLocation,"CateGory.CateGory2MediaFile.MediaFile2Maker");
