【问题描述】:
我正在尝试在选择单选按钮后立即对 gridview 中的记录进行排序。我的方法是使用数据视图,但由于数据集变量无法在往返服务器的过程中幸存下来,我不知道如何实现这一点。请帮忙!
Public Sub GetCustomers()
db.RunProcedure("usp_customers_get_all")
db.doSort(radList.SelectedValue)
gvCustomers.DataSource = db.MyView
End Sub
Protected Sub radList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles radList.SelectedIndexChanged
If radList.SelectedValue = 0 Then
db.doSort(0)
gvCustomers.DataSource = db.MyView
End If
If radList.SelectedValue = 1 Then
db.doSort(1)
gvCustomers.DataSource = db.MyView
End If
End Sub
Public Sub doSort(ByVal strIn As Integer)
If strIn = 0 Then
MyView.Sort = "lastname, firstname"
Else
MyView.Sort = "username"
End If
End Sub
Public Sub RunProcedure(ByVal strName As String)
Dim objConnection As New SqlConnection(mstrConnection)
Dim mdbDataAdapter As New SqlDataAdapter(strName, objConnection)
Try
mdbDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure
Me.mDataset.Clear()
mdbDataAdapter.Fill(mDataset, "tblCustomers")
MyView.Table = mDataset.Tables("tblCustomers")
Catch ex As Exception
Throw New Exception("stored procedure is " & strName.ToString & " error is " & ex.Message)
End Try
End Sub
