您好我正在尝试根据我的Web服务数据构建Gridview。
编译代码时我没有收到任何错误,但是gridview没有显示。不确定这是否是因为我正在构建gridview错误或数据没有被正确拉出。 Web服务确实有效,因为我已对其进行了测试。
以下是我用来绑定gridview的代码:
Private Sub BindGrid()
Dim objVen As New ISISVendor.VendorInterfaceClient
Dim LoginResp As New ISISVendor.LoginResponse
Dim POResp As New ISISVendor.PoSummaryResponse
Dim pod As New ISISVendor.PoDetailResponse
Dim dt As New DataTable
dt.Columns.Add("Status")
dt.Columns.Add("Sender")
dt.Columns.Add("PO Number")
dt.Columns.Add("Date")
dt.Columns.Add("Action")
gvv.DataSource = dt
POResp = objVen.GetOpenPos("3274")
Dim dr As DataRow
If POResp.Pos.Count > 0 Then
For j As Integer = 0 To POResp.Pos.Count - 1
dr = dt.NewRow
dr.Item("Status") = POResp.Pos(j).Status
dr.Item("Sender") = "COMPANY TEST"
dr.Item("PO Number") = POResp.Pos(j).PoNumber
dr.Item("Date") = POResp.Pos(j).PoDate
dr.Item("Action") = ""
Next
End If
gvv.DataBind()
End Sub
答案 0 :(得分:0)
似乎您没有将数据行添加到数据表中 请尝试以下
POResp = objVen.GetOpenPos("3274")
Dim dr As DataRow
If POResp.Pos.Count > 0 Then
For j As Integer = 0 To POResp.Pos.Count - 1
dr = dt.NewRow
dr.Item("Status") = POResp.Pos(j).Status
dr.Item("Sender") = "COMPANY TEST"
dr.Item("PO Number") = POResp.Pos(j).PoNumber
dr.Item("Date") = POResp.Pos(j).PoDate
dr.Item("Action") = ""
dt.Rows.Add(dr)
Next
End If
gvv.DataSource = dt
gvv.DataBind()
