I need display parent and child or Master and detail table in two datagrids. The source table is not fixed. In winform, I added two databindings and used below method. However, there is no databindings in WPF. How can I migrated the previous Winform to WPF? (below code has been modified in WPF except for bindingsource1 and bindingsouce2）
Code:
Private Sub Main_Load(sender As Object, e As EventArgs) Handles MyBase.Loaded
Me.MasterDGV.ItemsSource = Me.BindingSource1
Me.DetailDGV.ItemsSource = Me.BindingSource2
End Sub
Private Sub LoadData()
Data = Nothing
Data = New DataSet
SourcePath = "C:\Quote Kit\Sourcefile\emg_A_US_CN_USD_CIP.xlsx"
Currency = "USD"
MyConnection = New System.Data.OleDb.OleDbConnection("provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + SourcePath + "; Extended Properties=Excel 12.0;")
MasterAdapter = New System.Data.OleDb.OleDbDataAdapter("select Partnumber,Option,Description," & Currency & " from [Sheet1$] where partnumber=option", MyConnection)
DetailAdapter = New System.Data.OleDb.OleDbDataAdapter("select Partnumber,Option,Description," & Currency & " from [Sheet1$] where partnumber<>option", MyConnection)
MasterAdapter.Fill(Data, "Parent")
DetailAdapter.Fill(Data, "Child")
MyConnection.Close()
End Sub
'Define Master and Detail binding source
Public Sub BindingData()
Try
Dim Data As DataSet = Me.GetDataSet()
Me.bindingsource1.datasource = Data
Me.BindingSource1.DataMember = "Parent"
Me.BindingSource2.DataSource = Me.BindingSource1
Me.BindingSource2.DataMember = "ParentChild"
Me.MasterDGV.ItemsSource = Me.BindingSource1
Me.DetailDGV.ItemsSource = Me.BindingSource2
Catch ex As Exception
End Try
End Sub
'Load Data
Public Function GetDataSet() As DataSet
LoadData()
Data.Relations.Add("ParentChild", Data.Tables("Parent").Columns("Partnumber"), Data.Tables("Child").Columns("Partnumber"))
Return Data
End Function
