在datagridview的拖拽事件中,我收到了这个错误:
这是我的拖拽事件的整个代码:
Private Sub DataGridView1_DragDrop(sender As Object, e As System.Windows.Forms.DragEventArgs) Handles DataGridView1.DragDrop
Dim clientPoint As Point = DataGridView1.PointToClient(New Point(e.X, e.Y))
Dim hit As DataGridView.HitTestInfo = DataGridView1.HitTest(clientPoint.X, clientPoint.Y)
Dim dgvr As DataGridViewRow = DirectCast(e.Data.GetData(GetType(DataGridViewRow)), DataGridViewRow)
Dim celldata As Object() = New Object(dgvr.Cells.Count) {}
For col As Integer = 0 To dgvr.Cells.Count - 1
celldata(col) = dgvr.Cells(col).Value
Next
Dim dt As New DataTable()
dt = ds_data.Tables(0)
Dim colCheckbox As DataColumn = dt.Columns.Add("Column1", GetType(Boolean))
Dim row As DataRow = dt.NewRow()
row.ItemArray = celldata
dt.Rows.InsertAt(row, hit.RowIndex)
dgvr.DataGridView.Rows.Remove(dgvr)
Dim sqlCmd As SqlCommand
sqlCmd = con.CreateCommand()
sqlCmd.CommandText = "update megatom_data_commande set ordre='" & hit.RowIndex & "' where id='" & DataGridView1.Rows(hit.RowIndex).Cells("ID").Value.ToString & "'"
Try
sqlCmd.ExecuteNonQuery()
DataGridView2.DataSource = ds_data2.Tables(0).DefaultView
DataGridView1.DataSource = ds_data.Tables(0).DefaultView
Dim CMD As New SqlCommand("PLANNIFIER")
CMD.Parameters.Add("@CHAINE", SqlDbType.VarChar).Value = cboChaine.SelectedItem.ToString
ExecuteCMD(CMD)
Catch ex As SqlException
End Try
End Sub
实际上我的数据表有15列,但我手动添加了一个复选框列来选择行,所以我觉得我有索引问题,但我不知道如何解决这个问题。
我的ds_data定义如下代码:
requestPlanifie = "select megatom_data_commande.id as ID,numéro,observation,moule,commande,id_etat,programme,ordre,moule,glav,Qté_commandée_Totale," _
& " Qté_coupée_cuir, Qté_coupée_synthétique, Qté_piquée, Qté_finie from megatom_data_commande" _
& " inner join dbo.MEGATOM_DATA_MOULE on megatom_data_moule.id=megatom_data_commande.id_moule " _
& " where id_chaine='" & cboChaine.Text & "' and ( id_etat='3' or id_etat='4') order by numéro asc,ordre asc"
Dim dataAdapter As New SqlDataAdapter(requestPlanifie, con)
Try
dataAdapter.Fill(ds_data, "ds_data")
dataAdapter2.Fill(ds_data2, "ds_data2")
Catch ex As SqlException
End Try
DataGridView1.DataSource = ds_data.Tables(0).DefaultView
