Page_load event firing twice. User control not properly loading
- by Phil
Here is the code I am using to pull my usercontrol (content.ascx):
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'load module
If TheModule = "content" Then
Dim control As UserControl = LoadControl("~\Modules\Content.ascx")
Controls.Add(control)
End If
End Sub
Within the usercontrol is the following code (data access taken care of by DAAB and ive replaced sql statements with 'sql'):
Imports System.Data.SqlClient
Imports System.Data
Imports System.Web.Configuration
Imports Microsoft.Practices.EnterpriseLibrary.Common
Imports Microsoft.Practices.EnterpriseLibrary.Data
Partial Class Modules_WebUserControl
Inherits System.Web.UI.UserControl
Dim db As Database = DatabaseFactory.CreateDatabase()
Dim command As SqlCommand
'database
Dim reader As IDataReader
'general vars
Dim pageid As Integer
Dim did As Integer
Dim contentid As Integer
Dim dotpos As String
Dim ext As String
Dim content As String
Dim folder As String
Dim downloadstring As String
Function getimage(ByVal strin As String) As String
If strin > "" Then
dotpos = InStrRev(strin, ".")
ext = Right(strin, Len(strin) - dotpos)
getimage = ext & ".gif"
Else
getimage = String.Empty
End If
Return getimage
End Function
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load, Me.Load
'test
Response.Write("(1 Test from within page_load)")
'get session vars
folder = Session("folder")
pageid = Session("pageid")
did = Session("did")
'main content
command = db.GetSqlStringCommand("sql")
db.AddInParameter(command, "@pageid", DbType.Int32, pageid)
reader = db.ExecuteReader(command)
While reader.Read
If reader("content") IsNot DBNull.Value Then
content = Replace(reader("content"), Chr(38) + Chr(97) + Chr(109) + Chr(112) + Chr(59) + Chr(98) + Chr(104) + Chr(99) + Chr(112) + Chr(61) + Chr(49), "")
If reader("id") IsNot DBNull.Value Then
contentid = reader("id")
End If
Else
contentid = -1
content = String.Empty
End If
End While
Outputcontent.Text = content
'contacts info
If did = 0 Then
command = db.GetSqlStringCommand("sql")
db.AddInParameter(command, "@contentid", DbType.Int32, contentid)
reader = db.ExecuteReader(command)
While reader.Read()
Contactinforepeater.DataSource = reader
Contactinforepeater.DataBind()
End While
End If
If Not did = 0 Then
command = (db.GetSqlStringCommand("sql")
db.AddInParameter(command, "@contentid", DbType.Int32, contentid)
db.AddInParameter(command, "@did", DbType.Int32, did)
reader = db.ExecuteReader(command)
While reader.Read
Contactinforepeater.DataSource = reader
Contactinforepeater.DataBind()
End While
End If
'downloads box
command = db.GetSqlStringCommand("sql")
db.AddInParameter(command, "@contentid", DbType.Int32, contentid)
reader = db.ExecuteReader(command)
While reader.Read
If reader("filename") IsNot DBNull.Value Then
downloadstring += "<a href='/documents/" & folder & "/" & reader("filename") & "'>"
downloadstring += "<img src=images/" & getimage(reader("filename")) & " border=0 align=absmiddle />"
End If
If reader("filesize") IsNot DBNull.Value Then
downloadstring += Convert.ToInt32((reader("filesize") / 1000)) & "kb - "
End If
If reader("filename") IsNot DBNull.Value Then
downloadstring += "<a href='/documents/" & Session("folder") & "/" & reader("filename") & "'>" & reader("description") & "</a><br />"
End If
End While
Dim downloadsarray As ArrayList
downloadsarray = New ArrayList
If downloadstring IsNot Nothing Then
downloadsarray.Add(downloadstring)
End If
If downloadsarray.Count > 0 Then
DownloadsRepeater.DataSource = downloadsarray
DownloadsRepeater.DataBind()
End If
'get links
command = db.GetSqlStringCommand("sql")
db.AddInParameter(command, "@contentid", DbType.Int32, contentid)
reader = db.ExecuteReader(command)
While reader.Read
Linksrepeater.DataSource = reader
Linksrepeater.DataBind()
End While
End Sub
End Class
Now instead of seeing my page content and what should be within the repeaters on the page all I get is 2 x the output of Response.Write("(1 Test from within page_load)")
(1 Test from within page_load)(1 Test from within page_load)
This leads me to believe the page_load is firing twice, but not properly displaying all the information.
Please can one of you willing experts help me to get this working?
Thanks a lot in advance
