我是vb.net的新手,一直在尋找解決方案。我涉及的表單是MainMenu,poCustom和rdlcForm。所有工作都很好,直到我用MDI表格重新煥然一新。如何從sa MDI表單Groupbox獲取文本框的值?
我的「新」MainMenu現在將poCustom包含到Groupbox中。我搜索的代碼
For Each f As Form In Application.OpenForms
If TypeOf f Is poCustom Then
f.Activate()
Return
End If
Next
Dim ch As New poCustom
ch.TopLevel = False
ch.Visible = True
ch.StartPosition = FormStartPosition.Manual
Dim leftStart As Integer = 1220 - (ch.Width + (SystemInformation.Border3DSize.Width * 2))
Dim topStart As Integer = 670 - (ch.Height + (SystemInformation.Border3DSize.Height * 2))
ch.Location = New Point(leftStart, topStart)
GroupBox1.Controls.Add(ch)
問題:的rdlcForm(報告)不能得到poCustom形式的文本框的值。代碼如下:
Private Sub rptPOView2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim rptParam1(11) As Microsoft.Reporting.WinForms.ReportParameter
rptParam1(0) = New Microsoft.Reporting.WinForms.ReportParameter("rptDate", poCustom.Label1.Text)
rptParam1(1) = New Microsoft.Reporting.WinForms.ReportParameter("rptREF", poCustom.Label5.Text)
rptParam1(2) = New Microsoft.Reporting.WinForms.ReportParameter("rptCompany", poCustom.CompanyName.Text)
rptParam1(3) = New Microsoft.Reporting.WinForms.ReportParameter("rptQTY", poCustom.txBoxQTY.Text)
rptParam1(4) = New Microsoft.Reporting.WinForms.ReportParameter("rptUOM", poCustom.txBoxUOM.Text)
rptParam1(5) = New Microsoft.Reporting.WinForms.ReportParameter("rptDesciption", poCustom.txBoxDesc.Text)
rptParam1(6) = New Microsoft.Reporting.WinForms.ReportParameter("rptUnit", poCustom.txBoxUnit.Text)
rptParam1(7) = New Microsoft.Reporting.WinForms.ReportParameter("rptTotal", poCustom.txBoxTotal.Text)
rptParam1(8) = New Microsoft.Reporting.WinForms.ReportParameter("rptSubTotal", poCustom.Label25.Text)
rptParam1(9) = New Microsoft.Reporting.WinForms.ReportParameter("rptVAT", poCustom.Label26.Text)
rptParam1(10) = New Microsoft.Reporting.WinForms.ReportParameter("rptTotalAmount", poCustom.Label27.Text)
rptParam1(11) = New Microsoft.Reporting.WinForms.ReportParameter("rptRequest", poCustom.Label30.Text)
ReportViewer1.LocalReport.SetParameters(rptParam1)
Me.ReportViewer1.RefreshReport()
TextBox1.Text = poCustom.CompanyName.Text
End Sub
哪一個恰好在沒有使用MDI Forms的情況下工作。我想知道未來使用問題的原因。先謝謝你!
什麼是'poCustom'?並且不應該使用'POForm'而不是'poCustom',例如'ReportParameter(「rptDate」,POForm.Label1.Text)' – Arman
非常抱歉,我有兩種形式的Purchase Order,poDefault和poCustom。我會更新我的問題對不起。 – user3214105
我想你正在使用不同的poCustom實例 – Arman
