Hello,

I have a server button on my page. This button is use to open a serach page.
In the Page_Load event, I code this

If (Not Page.IsClientScriptBlockRegistered("clientScript")) Then
Page.RegisterClientScriptBlock("clientScript",
mpstrGetOpenSearchDialogScript)
End If

If Not IsPostBack Then
cmdSearch.Attributes.Add("onclick", "OpenSearchDialog();")
End If

Private Function mpstrGetOpenSearchDialogScript() As String

Dim strScript As String = ""

strScript += "<script language=""javascript"">" + Environment.NewLine
strScript += " function OpenSearchDialog()" + Environment.NewLine
strScript += " {" + Environment.NewLine
strScript += " var winSettings = 'center:yes;resizable:no;help:no;'" +
Environment.NewLine
strScript += " + 'status:no;dialogWidth:960px;dialogHeight:495px';" +
Environment.NewLine
strScript += " window.showModalDialog('frmSearch.aspx', '',
winSettings);" + Environment.NewLine
strScript += " }" + Environment.NewLine
strScript += "</script>" + Environment.NewLine
Return strScript

End Function

This code open a dialog window and it works perfectly. My problem is that I
need to set Session variables before the window opens. The server click
event of my button execute afther the window is close by the user. Is it
possible to set my session variables before the window is open when I click
on my search button?

Thank you!

Not without a postback...but if you are just trying to get a small amount of
data to frmSearch.aspx (the new window) then you can just pass the
querystring, IE:

strScript += " window.showModalDialog('frmSearch.aspx?id=xxx', ...


HTH :)

You could use an XmlHTTPRequest object on the client to do a server
call, this would call a server side aspx page which sets the session
variable,

or you could open a page that sets the session variable, then redirects
to the search page

Which session variables do you need to set? Why can't you set them
before the user even gets a chance to click on the button to open the
search dialog?
