在线等!急!急!急! datagridview更新问题
Dim conn As SqlConnection = New SqlConnection
conn.ConnectionString = connectionString
Dim sql1, sql2 As String
sql1 = "select * from codetype where typeid like '" & TextBox2.Text & "%'"
sql2 = "select * from codeitem where typeid like '" & TextBox2.Text & "%'"


Dim data As New DataSet()
'data.Locale = System.Globalization.CultureInfo.InvariantCulture

Dim masterDataAdapter As New SqlDataAdapter()
masterDataAdapter.SelectCommand = New SqlCommand(sql1, conn)
Dim cb1 As SqlCommandBuilder = New SqlCommandBuilder(masterDataAdapter)
masterDataAdapter.Fill(data, "codetype")


Dim detailsDataAdapter As New SqlDataAdapter()
detailsDataAdapter.SelectCommand = New SqlCommand(sql2, conn)
Dim cb2 As SqlCommandBuilder = New SqlCommandBuilder(detailsDataAdapter)
detailsDataAdapter.Fill(data, "codeitem")


masterDataAdapter.Update(data, "codetype")
detailsDataAdapter.Update(data, "codeitem")
data.AcceptChanges()
'If data.HasChanges Then



'data.Tables(1).AcceptChanges()
' End If

Dim parentCol As DataColumn
Dim childCol As DataColumn

parentCol = data.Tables("codetype").Columns("typeid")
childCol = data.Tables("codeitem").Columns("typeid")

Dim relation As New DataRelation("typeitem", _
data.Tables("codetype").Columns("TypeID"), _
data.Tables("codeItem").Columns("TypeID"))
data.Relations.Add(relation)





masterBindingSource.ResetBindings(False)
detailsBindingSource.ResetBindings(False)


masterBindingSource.DataSource = data
masterBindingSource.DataMember = "codetype"


detailsBindingSource.DataSource = masterBindingSource
detailsBindingSource.DataMember = "typeitem"

Me.DataGridView2.DataSource = masterBindingSource
Me.DataGridView1.DataSource = detailsBindingSource

这是我写在"更新"按钮下的代码,为什么数据库更新不了啊?
大侠们帮帮忙啊!

[解决办法]
好像要加上这一句哟:detailsDataAdapter.UpdateCommand=cb2.GetUpdateCommand
[解决办法]
MARK，这个问题我也遇到了
