我有一个datagridview,结果已经清除然后加载其他结果。这就是正在发生的事情。它在VB中。
继承我的代码:
Private Sub Button6_Click(sender As Object, e As EventArgs) Handles Button6.Click
ds.Clear()
ds.Tables.Clear()
resultsTable.DataSource = ds
Dim str As String = "Data Source=" & My.Settings.dbServer & ";uid=" & My.Settings.dbUsername & ";pwd=" & My.Settings.dbPassword & ";database=" & My.Settings.dbDatabase
Dim con As New SqlConnection(str)
Dim com As String = "SELECT *
FROM Scripts
where completed = 2
group by PrescriptionID"
Dim Adpt As New SqlDataAdapter(com, con)
Adpt.Fill(ds, "Emp")
resultsTable.DataSource = ds.Tables(0)
End Sub
由于
答案 0 :(得分:0)
尝试使用 resultsTable.Rows.Clear() 在第三行之后
