如何从另一个页面获取文本框或下拉列表的值？

Question

我需要从另一个页面获取文本框或下拉列表的值，以便编辑特定记录。

我在EditEmployee页面

中有一个业务组详细信息的gridview列表

如果我点击更新链接按钮，它将成功更新，包括HeadCountUpdating页面中的记录，但我只需要在headcountupdating页面中的特定年份和期间编辑记录

如何从其他页面获取文本框的值以便将其放在我的查询中？

        Dim JobTitle As String = DirectCast(gvGroup.Rows(e.RowIndex).FindControl("txtgvJobTitle"), TextBox).Text
        Dim BusinessUnit As String = DirectCast(gvGroup.Rows(e.RowIndex).FindControl("ddl_gvBusinessUnit"), DropDownList).Text
        Dim Division As String = DirectCast(gvGroup.Rows(e.RowIndex).FindControl("ddl_gvDivision"), DropDownList).Text
        Dim SubDivision As String = DirectCast(gvGroup.Rows(e.RowIndex).FindControl("ddl_gvSubDivision"), DropDownList).Text
        Dim Classification As String = DirectCast(gvGroup.Rows(e.RowIndex).FindControl("ddl_gvClassification"), DropDownList).Text
        Dim SubClassification As String = DirectCast(gvGroup.Rows(e.RowIndex).FindControl("ddl_gvSubClassification"), DropDownList).Text
        Dim MASTERID As String = DirectCast(gvGroup.Rows(e.RowIndex).FindControl("lblMasterID"), Label).Text
        Dim empno As String = lblval_Empno.Text
        Dim updatePeriodTblResult As Boolean

updatePeriodTblResult = UpdateInsDelRecord("UPDATE PERIOD_TBL SET BUSINESS_UNIT = '" & BusinessUnit & "', DIVISION = '" & Division & "'," & _
                                                           "SUB_DIVISION = '" & SubDivision & "', CLASSIFICATION = '" & Classification & "'," & _
                                                           "SUB_CLASSIFICATION = '" & SubClassification & "', JOBTITLE = '" & JobTitle & "' " & _
                                                           "WHERE MASTERID = '" & MASTERID & "' AND EMPNO = '" & empno & "'")

• 在源页面中，保存要在会话状态中传递的信息
  Session("field1") = "value1"

• 在目标页面中，从会话状态中读取已保存的信息 Dim field1 as String = CType(Session.Item("field1"), String)
