Question

How to use "Web form user control" in asp.net?

Asked by: ptri

I have a user control named pagelet4.ascx (example of .NET):

<script language="VB" runat="server">

  Public BackColor As String = "white"

  Public Property UserId As String
    Get
      Return UserName.Text
    End Get
    Set
      UserName.Text = Value
    End Set
  End Property

  Public Property Password As String
    Get
      Return Pass.Text
    End Get
    Set
      Pass.Text = Value
    End Set
  End Property

</script>

<table style="background-color:<%=BackColor%>;font: 10pt verdana;border-width:1;border-style:solid;border-color:black;" cellspacing=15>
  <tr>
    <td><b>Login: </b></td>
    <td><ASP:TextBox id="UserName" runat="server"/></td>
  </tr>
  <tr>
    <td><b>Password: </b></td>
    <td><ASP:TextBox id="Pass" TextMode="Password" runat="server"/></td>
  </tr>
  <tr>
    <td></td>
    <td><ASP:Button Text="Submit" runat="server"/></td>
  </tr>
</table>


I want to use "userId propety"  of pagelete4.ascx in another web form named "pagelet4.aspx.vb" (not in pagelet4.aspx as in example). How can I do?

Please help me!

Thank in advance!

    I do not think this is possible in the way you envisage it. It would be great if it was. However, I feel you need to expand your user control to put the values into session state so that they are available across page invokations.

    like:

    Public Property UserId As String
       Get
         Return UserName.Text
       End Get
       Set
         UserName.Text = Value
         session("Username") = value
       End Set
     End Property

     Public Property Password As String
       Get
         Return Pass.Text
       End Get
       Set
         Pass.Text = Value
         Session("Pass")=value
       End Set
     End Property

    These would then be available from any page in the session. You could even expand the usercontrol even more to check if the session values are present and pre-set the properties for the user.

    Try this  if the pagelet4.aspx.vb is in the same project

    1)Drag and drop the usercontrol from the solution explorer to the webform control

    2)Give an id to the user control  say login1.

    3)In the code behind file(pagelet4.aspx.vb) change the class modifier  to public(orginally mustinherit).

    4)Declare the variable pointing to usercontrol
    Protected WithEvents l1 As pagelet4(It is not automatically added as webform controls)

    5)Get a reference to the  usercontol from the page_load by

    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
       
     11 = DirectCast(FindControl("login1"), pagelet4)  
     End Sub
     
    6)Form any events ay button_click get the value
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
            If Page.IsPostBack Then
             response.write(l1.password)
    end if

    I hope this will work

    Joe
