Hi,

I'm developing a website with a global masterpage - this masterpage has a search box and submit button with its PostBackURL set to "Search.aspx".

When I submit the form using this button, I can easily access the text value of this search box like so:

My getter set up in the MainMasterFile.master:

1    <%@ Master Language="VB" ClassName="MainMasterFile" %>
2    
3    <script runat="server">
4        Public ReadOnly Property SearchString() As String
5            Get
6                Return SearchTextBox.Text
7            End Get
8        End Property
9    </script>

 In Search.aspx.vb in Page_Load:

1            If (Page.PreviousPage IsNot Nothing AndAlso PreviousPage.IsCrossPagePostBack) Then
2                searchString = CType(PreviousPage.Master, ASP.MainMasterFile).SearchString
3            Else
4                searchString = Master.SearchString
5            End If

This all works fine until I add a "repeat" search box onto Search.aspx which includes more advanced forms of searching, now I have 3 routes to loading this page:

1. From another page (PreviousPage.IsCrossPagePostBack = True) using the masterpage textbox
2. From Search.aspx using the masterpage textbox (PreviousPage.IsCrossPagePostBack = False)
3. From Search.aspx using the page declared search textbox

Is there anyway I can differenciate routes 2 and 3?  I need them to have different behaviours when Page_Load is run.

Thanks,

Hi,

After playing around and searching I came up with a perfect solution, incase anyone else is having this issue:

In page_load of Search.aspx.vb I registered a Handler:

AddHandler Master.SearchButton.Click, AddressOf MasterPageSearchButton_Click

(you will need to cast Master to your particular masterfile, or add MasterType declaration at the top of Search.aspx) so when Search.aspx was active, it handled the master page click.

Now I have 2 click events (one for the Search.aspx advanced search, one for the masterpage quick-search button) and the page load IsCrossPagePostBack if statement to handle each of the eventualities.
