从GridView获取RepositoryLookupEdit

Question

我想遍历gridview中的所有行并从RepositoryLookupEdit中检索数据。

基本上我想这样做，但我不知道如何让RepositoryLookupEdit：

For i as Int32 = 0 to myGridView.RowCount -1 
    Dim row As DataRowView = CType(myGridView.GetRow(i), DataRowView) 
    //'This next line does not work 
    Dim lue As LookUpEdit = row.Item("myColumn").myRepLookupEdit 
    Dim drv As DataRowView = CType(editor.Properties.GetDataSourceRowByKeyValue(lue.EditValue), DataRowView) 
    Dim myData As Int32 = CType(drv("myData"), Int32) 
Next

我认为你应该使用下面的代码：

For i as Int32 = 0 to myGridView.RowCount -1 

    Dim cellValue As object = myGridView.GetRowCellValue(i, "myColumn") 
    dim dView as DataView = new DataView(repositoryItemGridLookupEdit.DataSource) ' you should pass a DataTable instance here 

    dim rowIndex as integer = dView.Find(cellValue) 
    dim otherCellValue as object = dview(rowIndex)("myData") 
Next 

不这个工作给你？
