两个DataGridView控件数据绑定
程序中有两个DataGridView控件，第一个和第二个显示相同的数据，但是第二个数据可以更改，而第一个作为参照不可更改，
但是 当第二个DataGridViewComboBoxColumn控件变更的时候，第一个控件的第二例却跟着变更，不是想要的结果，这是为什么
Dim allCaseView As New DataView(allCaseMst.M_Case)
allCaseView.Sort = allCaseMst.M_Case.CaseCodeColumn.ColumnName
With colAfterCaseName
.DisplayMember = allCaseMst.M_Case.CaseNameColumn.ColumnName
.ValueMember = allCaseMst.M_Case.CaseCodeColumn.ColumnName
.DataSource = allCaseView
End With
Dim copyCaseMst As DS.DSCaseCodeChange = caseMst
Dim copyCaseView As New DataView(copyCaseMst.M_Case)
copyCaseView.Sort = copyCaseMst.M_Case.CaseCodeColumn.ColumnName
With dgvBefordChangeCase
.DataSource = Nothing
.Columns(colBeforeCaseCode.Index).DataPropertyName = copyCaseMst.M_Case.CaseCodeColumn.ColumnName
.Columns(colBeforeCaseName.Index).DataPropertyName = copyCaseMst.M_Case.CaseNameColumn.ColumnName
.DataSource = copyCaseView
End With
Dim caseView As New DataView(caseMst.M_Case)
caseView.Sort = caseMst.M_Case.CaseCodeColumn.ColumnName
With dgvAfterChangeCase
.DataSource = Nothing
.Columns(colAfterCaseCode.Index).DataPropertyName = caseMst.M_Case.CaseCodeColumn.ColumnName
.Columns(colAfterCaseName.Index).DataPropertyName = caseMst.M_Case.CaseNameColumn.ColumnName
.DataSource = caseView
End With
[解决办法]
你绑定的数据应该是同一个datatable or dataview
