Question

我有一个Gridview和一个按钮。当我点击按钮然后显示消息，但之后我的Gridview的格式不像以前那样正确。

请在下面的图片中查看更多内容： Gridview incorrect format after close message

我使用下面的代码显示消息：

HttpContext.Current.Response.Write("<script>alert('Đã tồn tại nguồn đơn " & name & ". Bạn không thể tạo thêm được nguồn đơn này nữa')</script>")
Return

=＆GT;如何保持普通格式？

以下代码我使用：

Private Sub grvData_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles grvData.RowCommand
lblError.Text = String.Empty
Dim commandNameType As String = String.Empty
Try
    If e.CommandName = "Insert" Then
        commandNameType = "thêm"
        Dim txtName As TextBox = DirectCast(grvData.FooterRow.FindControl("txtNewName"), TextBox)
        Dim cboStatus As DropDownList = DirectCast(grvData.FooterRow.FindControl("ddlNewStatus"), DropDownList)

        lblError.Text = String.Empty
        Try
            If String.IsNullOrEmpty(txtName.Text) Then
                Return
            End If
            Dim pSource As New TblPetitionSource
            pSource.Name = txtName.Text
            pSource.Lastupdate = Now.ToString("yyyy/MM/dd HH:mm:ss")
            pSource.StatusFlag = 1
            pSource.UpdateBy = "ADMIN"

            Dim db As New ProcuracyDataContext
            Dim lst = (From p In db.TblPetitionSource Where p.Name = txtName.Text Select p).ToList()
            If lst.Count > 0 Then
                HttpContext.Current.Response.Write("<script>alert('Đã tồn tại nguồn đơn . Bạn không thể tạo thêm được nguồn đơn này nữa')</script>")
                Return
            End If

            db.TblPetitionSource.InsertOnSubmit(pSource)
            db.SubmitChanges()
            BindData()

        Catch ex As Exception
            lblError.Text = ex.Message
        End Try
    End If
Catch ex As Exception
    lblError.Text = "Lỗi không " & commandNameType & " được bản ghi này <br />" & ex.Message
End Try

End Sub

这是我用于MergeCells的代码：

Private Sub grvData_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grvData.RowDataBound
   Try
       If e.Row.RowType = DataControlRowType.Header Then
           e.Row.Cells.RemoveAt(e.Row.Cells.Count - 1)
           e.Row.Cells(e.Row.Cells.Count - 1).ColumnSpan = 2
           e.Row.Cells(e.Row.Cells.Count - 1).Text = "Thao tác"
       End If
       If e.Row.RowType = DataControlRowType.Footer Then
           e.Row.Cells.RemoveAt(e.Row.Cells.Count - 1)
           e.Row.Cells.RemoveAt(e.Row.Cells.Count - 1)
           e.Row.Cells.RemoveAt(e.Row.Cells.Count - 1)
           e.Row.Cells(e.Row.Cells.Count - 1).ColumnSpan = 4
       End If
   Catch ex As Exception
       Throw New Exception(ex.Message, ex)
   End Try

End Sub
