Question

如果该网格行的“数量”为“0”，如何阻止用户选择网格行的复选框。我有下面的代码，但它仍然允许，因为只要选择了一行，它就允许选择第二行，依此类推而不更改Qty值。然后将上面每个按钮的选定行发送到form2。

public Test()

        sqlite = new SQLiteConnection("Data Source=C:/MyCedarDataConn/CedarPaints.db;");

        DataColumn[] dataColumn = new DataColumn[] { new DataColumn("ProdCode"), new DataColumn("Product"),  new DataColumn("Pack"), new DataColumn("t1"), new DataColumn("t2"), new DataColumn("Qty"), new DataColumn("WSale") };
        columns.AddRange(dataColumn);

您可以使用在所选单元格的编辑模式启动时发生的CellBeginEdit事件。

Private Sub YourDataGridView_CellBeginEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellCancelEventArgs) Handles YourDataGridView.CellBeginEdit

    Try
        With Me.YourDataGridView
            If .Columns(e.ColumnIndex).Name = "YourCheckBoxColumnName" AndAlso .Rows(e.RowIndex).Cells("YourQuantityColumnName").Value > 1 Then
                e.Cancel = True
            End If
        End With
    Catch ex As Exception
    End Try

End Sub

如果数量不大于1，则选中停止复选框
