根据控件名查找页面控件

        For i = 0 To dtScreenControl.Count - 1
            Dim controlFirstName = dtScreenControl(i).ControlName.Substring(0, 3)
            Dim value = dtScreenControl(i).SettingValue
            Select Case controlFirstName
                Case "chk"
                    Dim chk As CheckBox = DirectCast(Page.Master.FindControl("ContentBodyPlaceHolder").FindControl(dtScreenControl(i).ControlName), CheckBox)
                    chk.Checked = CBool(value)
                Case "ddl"
                    Dim ddl As DropDownList = DirectCast(Page.Master.FindControl("ContentBodyPlaceHolder").FindControl(dtScreenControl(i).ControlName), DropDownList)
                    ddl.SelectedValue = dtScreenControl(i).SettingValue
                Case "grb"
                    Dim grb = DirectCast(Page.Master.FindControl("ContentBodyPlaceHolder").FindControl(dtScreenControl(i).ControlName), RadioButton)
                    grb.Checked = CBool(value)
                Case "txt"
                    Dim txt = DirectCast(Page.Master.FindControl("ContentBodyPlaceHolder").FindControl(dtScreenControl(i).ControlName), TextBox)
                    txt.Text = value
