That got me a step closer. uc1:MyField now shows up in intelisense. However the build fails saying that Unknown server tag 'uc1:MyField'. I am not using any custom namespaces
This is my markup
<uc1:MyControll ID="MyControll1" runat="server">
<MyFields>
<uc1:MyField MyProperty="This" />
<uc1:MyField MyProperty="That" />
<uc1:MyField MyProperty="You" />
</MyFields>
</uc1:MyControll>
This is my register tags
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register Src="MyControll.ascx" TagName="MyControll" TagPrefix="uc1" %>
<%@ Register TagPrefix="uc1" Namespace="ASP"%>
Thoughts?

You now simply define the MyField in a namespace and replace the ASP with that value. My mistake here is that the default namespace of the MyField class will be empty, not ASP like the dynamic of the web pages, and the Namespace attribute of the Regsiter directive does not allow an empty value, sorry about this. Also, I'm not sure if you know this fact or not, but when you switch to the Design view you will see the the designer reports the error on the web user control. The only way to work around this error is to use a custom web control.

The designer error is kind of annoying. Does anyone know to work around that? I made this a server control and have it working like i want. The class is inheriting from CompositeControl, I even added a Designer class and handled the GetDesignErrorHTML override, or whatever its called, and I still get the error. Its not serious as it still compiles and functions as expected, but it looks rather unprofessional.

Yeah, it's quite annoying as far as the design support is concerned, and afaik this is the limitation of the product in supporting the web user control at design time. The parser always looks at the UserControl class when a web user control is placed in the web page while it should look at the real control or at least the base class of the web user control.

He can learn a lot from the code snippest...
(At least I hope  )

He'll learn to copy and paste

yep that is correct he should have tried it first and then in case of problem should have asked here.

hi, can anyone help me on this problem thats occurring. I created a forum and its like this .. www.ivanandsimone.com/Query/Home.aspx. Now the problem is this, when i enter in the home.aspx 3 imagebuttons of 3 different items are shown above the page for instance (mobile, computer and book). When someone click on a picture it will take him in its (item description) of that item.
at that point everything works well but when a person clicks the back button of the windows explorer from the taskbar .. the pictures will ramins the same (mobile, computer and book) but the sessions will be overwrited by other numbers.
I am using Sessions to store every picture (the 3 pictures) ID number and then send that ID number to the Item.aspx page. The Item.aspx page will then see the ID and from the database it will search for the information about that ID that the user chosen.
Now the code is this:
This is for the Page_Load
If Request.QueryString("ItemID") <> "" Then<br />
Session(ID) = Request.QueryString("ItemID")<br />
<br />
Response.Redirect("Item.aspx")<br />
End If<br />
<br />
If Not IsPostBack Then<br />
Try<br />
odcConn = New OleDbConnection(strConn)<br />
daMem = New OleDbDataAdapter("Select * From tblItems Order By ItemID Desc", odcConn)<br />
dsMem.Clear()<br />
daMem.Fill(dsMem, "tblItems")<br />
dgItems.SelectedIndex = -1<br />
dgItems.DataSource = dsMem.Tables("tblItems")<br />
dgItems.DataBind()<br />
odcConn.Close()<br />
Session("Num1") = Nothing<br />
Session("Num2") = Nothing<br />
Session("Num3") = Nothing<br />
FillCategories()<br />
Catch ex As Exception<br />
odcConn.Close()<br />
End Try<br />
End If<br />
<br />
ChooseItems()<br />
End Sub
So the sessions - Session("Num1") and the other 2 are the storeage that i told you. Now for the Image Picker of the ImageButtons I am using this code:
Private Sub ChooseItems()<br />
Dim strImage As String<br />
Dim strItem As String<br />
Dim daItem As OleDbDataAdapter<br />
Dim ds As New DataSet<br />
Dim i As Integer = 0<br />
<br />
Dim randNum As New Random<br />
Dim intNum As Integer = randNum.Next(0, 22)<br />
<br />
odcConn = New OleDbConnection(strConn)<br />
daItem = New OleDbDataAdapter("SELECT * FROM tblItems", odcConn)<br />
daItem.Fill(ds, "tblItems")<br />
<br />
Try<br />
strImage = ds.Tables("tblItems").Rows(intNum)("Image1")<br />
<br />
imgItem1.ImageUrl = strImage<br />
<br />
strItem = ds.Tables("tblItems").Rows(intNum)("Item")<br />
<br />
lblItem1.Text = "Item: " & strItem<br />
<br />
If Session("Num1") = Nothing Then<br />
Session("Num1") = ds.Tables("tblItems").Rows(intNum)("ItemID")<br />
End If<br />
Catch ex As Exception<br />
odcConn.Close()<br />
Exit Try<br />
End Try<br />
<br />
intNum = randNum.Next(0, 22)<br />
daItem = New OleDbDataAdapter("SELECT * FROM tblItems", odcConn)<br />
daItem.Fill(ds, "tblItems")<br />
<br />
Try<br />
strImage = ds.Tables("tblItems").Rows(intNum)("Image1")<br />
<br />
imgItem2.ImageUrl = strImage<br />
<br />
<br />
strItem = ds.Tables("tblItems").Rows(intNum)("Item")<br />
<br />
lblItem2.Text = "Item: " & strItem<br />
<br />
If Session("Num2") = Nothing Then<br />
Session("Num2") = ds.Tables("tblItems").Rows(intNum)("ItemID")<br />
End If<br />
Catch ex As Exception<br />
odcConn.Close()<br />
Exit Try<br />
End Try<br />
<br />
intNum = randNum.Next(0, 22)<br />
daItem = New OleDbDataAdapter("SELECT * FROM tblItems", odcConn)<br />
daItem.Fill(ds, "tblItems")<br />
<br />
Try<br />
strImage = ds.Tables("tblItems").Rows(intNum)("Image1")<br />
<br />
imgItem3.ImageUrl = strImage<br />
<br />
strItem = ds.Tables("tblItems").Rows(intNum)("Item")<br />
<br />
lblItem3.Text = "Item: " & strItem<br />
<br />
If Session("Num3") = Nothing Then<br />
Session("Num3") = ds.Tables("tblItems").Rows(intNum)("ItemID")<br />
End If<br />
Catch ex As Exception<br />
odcConn.Close()<br />
Exit Try<br />
End Try<br />
<br />
odcConn.Close()<br />
End Sub
Can anyone help me in this problem  because I got a big headache trying to fix this problem all night!

that is a frequent problem with the back button, every time that the user press this button the page do nothing (postback or not postback), the solution is hide the address bar and forces the users to navigate back using a server hiperlink control from the page.
On the all htmls page write these head lines
...
These lines forces the explorer to reload all the images from the server
i Hope will be usefull for you
keep Learning and you never will be out of date...

I am VERY new to web development and have what is probably a simple question regarding SSL. (I have a lot of experience in VB, but not in web apps).
I have an SSL certificate installed on my windows 2003 server. What kind of code do I need to incorporate into my application to utilize the SSL? Is code necessary, or does IIS handle all that? Is there any code available?
I'm sure this stuff is second nature to you guys, but you gotta learn somewhere!

Hi to all,
How can I display when textbox losting the focus with asp.net validation controls?
I am having a ten textboxes(mandatory). I am using requirefield validator. This is working fine when I click the submit button.
I want to display the errormessage when the focus leaving from control(if textbox is empty).
Regards,

|

You just need to change the display property of the required field validator control to dynamic.
Best Regards,

I already worked on that. But the result is nothing. By using this, validation should be fired. but it can't?
Can I change any changes to webuivalidation.js?
I am using asp.net1.1. and iis5.1

i am new to asp.net now i want to know how to use the application state an session state
|
|
|
|

There are so many articles available on net about the same. one os them is this[^]
Best Regards,

I am new ,also, to both ASP and ASP.net and in both instances I am self taught. Nonetheless, let me try to explain what is and the usage of both session and application state. Application state refers to any data that you might want to share amongst (all)users while session state maintains the state for individual user. While values stored in the application state will remain until the application is restarted or deleted, session state values are removed and discared as soon as the user ends his/her session(either by logging off or closing the browser). A typical example of session state is a counter on a website which tells you "you are the Xth person visitng our site (whereby X respresent the number of visitors to the site since the application started). While session state will tell you "You're logged in as such "username" and have been on for the past X amount of minutes (per se).
To set/capture and access the values contained in specific state the following syntax can be used.
Session state (syntax)
Session["MySessionVar"] = "MyValue";
/*where by my value can be anything u want to use be it username, password(not advisable), userPreferences....and so on. */
//then you can assign it to a variable which you can use to access and print the value of Session value(s)
SessionAlias = Session["MySessionVar"];
//To output the value contained in your session can be
//written as (lets say used the login name as the session
//value).
Response.Write("You are currently logged-in as " + SessionAlias);
The application state (syntax) is quite same as the session syntax. The only difference is that instead of using keyword "Session" you use "Application".
I must admit that this is a very elementary explantion but I sincerely hope that it helps you to better understand the concept. Not to long ago I was exactly where you are now in learning ASP and ASP.net and though I have advanced somewhat, I still have a long way to go. The best way to learn these concepts and ideologies are to practice writing them. However if you are unfamiliar with their existence then there will be no inclination to learn them. As a novice programmer I've found out the best way to learn is to read as much source code as you can and anything that captures your attention you should write it down then find a season programmer and start questioning him away. Hopem this helps.
PS: I will stand corrected should any of the readers find my explanation is erroneous.

I have a database full of dates and events for a calendar. I can (and have, using ASP) created my own code to create and fill out a Calendar. Before I review my code and rewrite it using ASP.NET/VB.NET I want to make sure I can't use the Calendar control already provided. I need to have two views for this, the first looks like the basic calendar control but with a color code for repeating dates. Like say the Jan. 12th is Martin Luther King Jr. Day, I would like it's background yellow (basically have style="background-color:yellow" in the TD tag). The second need I have is to have a big calendar with actual text in the box, so on the 12th the text "Martin Luther King Jr. Day" would be in the box with the date. So the basic question is: Is there anyway to programmatically access the individual date cells?
