Dear All,
I am adding an ascx file into a content page and always I receive an unknown element error. Somehow In content page eventhough I register the ascx file, the control seems to be not known or recognized. Why do you think it happens? Here is my html code - do I miss something?
<%@ Page Language="C#" MasterPageFile="~/MAIN.Master" AutoEventWireup="true" CodeBehind="Urunler.aspx.cs" Inherits="cicektablo.Urunler" Title="flowerbox® Türkiye" %>
<%@ Register src="WebMessageBox.ascx" tagname="WebMessageBox" tagprefix="uc1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="body" runat="server">
<uc1:WebMessageBox ID="WebMessageBox1" runat="server" />
</asp:Content>
ps: I also checked the msdn and it is explianed in excatly my way. I do not understand.

If you need help with a specific error you should always give the exact text of the error message.
Is the user control in the same folder as the page? Did you try adding the user control by dragging and dropping into the design of the page or did you add it manually through in the aspx?

Thanks a lot for the answer it says webmessagebox(web user control) is not a known element... yes I tried dragging and dropping it... even so it gives the same error.
|

Here are a few things to try in whatever order you choose:
Make sure your control is in the same namespace as your pages or specify namespace in references.
Under the Build menu, Clean Solution, then rebuild.
Remove the control from the project completely, build, add it back and build again.
Create a new project file and add the pages and controls into it.

Hi guys.. I am working on a web application on Vb platform. Now in my application i have a button on clicking it generates an html table based on the records retrieved from my database.. Now the issue is I wanna rowspan certain cells in my html table for repeated Records... Now heres the code:
Private Sub BtnApp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnApp.Click
Response.Redirect("form_frameset.aspx?sno=&page=UserApplication&keyid=&keyinfo=All")
End Sub
on the above button click it navigates to another page where the Html table gets populated.. the code on the next page is as follows:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
Dim page As String = Request.QueryString("page")
Dim keyid As String = Request.QueryString("keyid")
Dim keyinfo As String = Request.QueryString("keyinfo")
MyConn = New OdbcConnection(Session("sybase_constr"))
Dim SelectCmd As OdbcCommand
If page = "UserApplication" Then
Dim sqlstring As String
If keyinfo = "All" Then
sqlstring = "Select ug.UserID,u.firstname, fg.GroupID, g.GroupDesc, f.FunctionID,f.FunctionDesc from EACS_Function f, EACS_UserGroup ug, EACS_FunctionGroup fg, EACS_Group g, EACS_user_1 u where f.ApplicationID='" & keyid & "' and fg.FunctionID = f.FunctionID and fg.GroupID = ug.GroupID and ug.userid = u.userid and fg.GroupID = g.GroupID order by ug.UserID"
End If
SelectCmd = New OdbcCommand(sqlstring, MyConn)
Dim DS As DataSet
Dim MyCommand As OdbcDataAdapter
MyCommand = New OdbcDataAdapter(SelectCmd)
MyConn.Open()
DS = New DataSet
MyCommand.Fill(DS)
Dim i As Integer
i = 0
If page = "UserApplication" Then
If DS.Tables(0).Rows.Count > 0 Then
InsertPageBreak()
InsertAppUserHeader()
For i = 0 To DS.Tables(0).Rows.Count - 1
PopulateAppUsrRow(DS.Tables(0).Rows(i)(0), DS.Tables(0).Rows(i)(1), DS.Tables(0).Rows(i)(2), DS.Tables(0).Rows(i)(3), DS.Tables(0).Rows(i)(4), DS.Tables(0).Rows(i)(5))
Next
Else
Response.Write("<script language=javascript > alert('Sorry no records found'); </script>")
End If
Private Sub PopulateAppUsrRow(ByVal Usrid As String, ByVal Usrname As String, ByVal Grpid As String, ByVal Grpdsc As String, ByVal Fncid As String, ByVal FncDsc As String)
Response.Write("<tr><td align=left>" + Usrid + "</td><td align=left >" + Usrname + "</td><td align=left >" + Grpid + "</td><td align=left >" + Grpdsc + "</td><td align=left >" + Fncid + "</td><td align=left >" + FncDsc + "</td></tr>")
End Sub
Private Sub InsertPageBreak()
Response.Write("</table></font><br style='PAGE-BREAK-BEFORE:always'>")
End Sub
Private Sub InsertAppUserHeader()
Response.Write("<font face=Arial ><table cellspacing=0 width=95% border=1 ><tr><td colspan=10 align=center ><b>Abu Dhabi Islamic Bank. <br> Application Management System. </b></td></tr>")
Response.Write("<tr><th align=center>User Id</th><th align=center >User Name</th><th align=center >Group Id</th><th align=center >Group Description</th><th align=center >Function Id</th><th align=center >Function Description</th></tr>")
End Sub
Now the table which gets populated is as follows:
National Bank.
Application Management System.
User Id User Name Group Id Group Description Function Id Function Description

| As you are creating the HTML already at server side.You have full control over the HTML what you have to show.Have some check at the time of creating table according to the data coming from DB. Set the rowspan.Check after the table is created,whether it is right or not.If not it means there is some problem in the creating the table. Cheers!!

Why, you just get the data from db, check how many records are there and where and howmauch rowsapn you need , you can decide if you are having data.Set it accordingly.You'll have to take decision of the count of rowspan after getting the data from DB. You can not hard code the rowspan.Cheers!!

The requirement is simply using 'control break logic'. Search for it.
Note that the sort order of the recordset is important.
Read the first record. Save the 'control break' (userid?, can be more than 1 value).
Write_All_Cells.
For every record after that...
Read.
If value same as saved 'control break' then
Write_Some_Cells (one td has a column span = n)
else
replace control break value
Write_All_Cells

Any sample code or articles plzz????
Thanx & regards,

Yes, that whole logic thing will get you everytime.
Dim connection As New SqlConnection("server=MyServer;Trusted_Connection=true;database=MyDatabase")
connection.Open()
Dim command As New SqlCommand("select MyKey,MyField1,MyField2 from MyTable order by MyKey;", connection)
Dim reader As SqlDataReader = command.ExecuteReader()
Response.Write("<table border='1'>")
'Read the first record
reader.Read()
'Set the control break
Dim ControlBreak As Integer = CInt(reader(0))
'Write all cells
Response.Write("<tr><td>" & reader(0) & "</td><td>" & reader(1) & "</td><td>" & reader(2) & "</td></tr>")
While reader.Read()
If reader(0).Equals(ControlBreak) Then
'Write some cells
Response.Write("<tr><td colspan='2'> </td><td>" & reader(2) & "</td></tr>")
Else
'Reset the control break
ControlBreak = CInt(reader(0))
'Write all cells
Response.Write("<tr><td>" & reader(0) & "</td><td>" & reader(1) & "</td><td>" & reader(2) & "</td></tr>")
End If
End While
Response.Write("</table>")
reader.Close()
connection.Close()

Thanx for ur reply... but in my code i dont use reader i store it in a dataset.... so working on it.. Any advice is appreciated..
Thanx in advence..

Thanx a lot i found another solution for my issue.... actually i used the following code to solve it...
i used String collection to store the value and checked it and printed the table accordingly
ElseIf page = "UserApplication" Then
If DS.Tables(0).Rows.Count > 0 Then
InsertPageBreak()
InsertAppUserHeader()
Dim nfile As StringCollection = New StringCollection
Session("sc1") = nfile
For i = 0 To DS.Tables(0).Rows.Count - 1
PopulateAppUsrRow(DS.Tables(0).Rows(i)(0), DS.Tables(0).Rows(i)(1), DS.Tables(0).Rows(i)(2), DS.Tables(0).Rows(i)(3), DS.Tables(0).Rows(i)(4))
'DataSetToExcel.Convert(DS, Response)
Next
Now the Html table gets populated by the following code:
Public Sub PopulateAppUsrRow(ByVal Usrid As String, ByVal Usrname As String, ByVal Grpid As String, ByVal Grpdsc As String, ByVal FncDsc As String)
If Not Session("sc1").Contains(Usrid) Then
Session("sc1").Add(Usrid)
Response.Write("<tr><td align=left>" + Usrid + "</td><td align=left >" + Usrname + "</td><td align=left >" + Grpid + "</td><td align=left >" + Grpdsc + "</td><td align=left >" + FncDsc + "</td></tr>")
Else
Response.Write("<tr><td align=left> </td><td align=left >" + Usrname + "</td><td align=left >" + Grpid + "</td><td align=left >" + Grpdsc + "</td><td align=left >" + FncDsc + "</td></tr>")
End If
End Sub
Im happy with this kinda output.. any advice is appreciated...
Thanx in advance...

hi, iam using asp.net2.0 with c# with sql server
the table fields are as follows
username nvarchar
password nvarchar
emailid nvarchar
usertype int(1=administrator,2=programmer,3=manager,4=user)
active bit
so based on the user types how to give access on each page and on controls like buttons. and for different users different permissions .can you give me example which helps me
|
|
|
|
|
For this, when user login to application ,also retrieve the type of user say administrator etc and save the type of user in session.And on every pageload, you can just check the type of user and accordingly yoy can take decision which buttions/links you need to disabe/hide.
And if user goes direcly to the page which is not for it ,you can show "Access Denied" message.Cheers!!

You can save the image path in database and store the image in physical location. So, when you are retreiving the from database, retreive the image path and then load the corresponding image from physical path.
You can have a look into this article as a ref.

Let me know if you need any help !Cheers !

Doesn't work like that: what happens is you try to work it out for yourself using the years of experience and knowledege you already have. Then when you are still stuck you come here and say 'This is what I have already tried: can you help me see where I am going wrong?'
In any case, if you googled you'd probably find a thoudand and one ways to do this.Tychotics
