accessing field from user control

[jhermiz]

got a question...


Lets say I have a user control for a calendar here is the html:

<%@ Control Language="vb" AutoEventWireup="false" Codebehind="CalendarControl.ascx.vb" Inherits="ims.jakah.com.CalendarControl" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
<asp:textbox id="txtIssueClosed" Width="64px" runat="server"></asp:textbox>
<INPUT style="BACKGROUND-POSITION-X: center; BACKGROUND-IMAGE: url(../images/calendar.gif); WIDTH: 24px; BACKGROUND-REPEAT: no-repeat; FONT-FAMILY: Arial, SansSerif, Verdana; HEIGHT: 24px"
 onclick="OnClick()" value="..." type="button">
<br>
<div id="divCalendar" style="DISPLAY: none; POSITION: absolute"><asp:calendar id="Calendar1" Width="200px" runat="server" CellPadding="4" BorderStyle="Outset"
  BorderColor="#C7D6E4" Font-Names="Arial" Font-Size="8pt" Height="180px" ForeColor="Black" BackColor="White" BorderWidth="2px">
  <TodayDayStyle ForeColor="Black" BackColor="#CCCCCC"></TodayDayStyle>
  <SelectorStyle BackColor="#CCCCCC"></SelectorStyle>
  <NextPrevStyle VerticalAlign="Bottom"></NextPrevStyle>
  <DayHeaderStyle Font-Size="7pt" Font-Bold="True" BackColor="#CCCCCC"></DayHeaderStyle>
  <SelectedDayStyle Font-Bold="True" ForeColor="White" BackColor="#666666"></SelectedDayStyle>
  <TitleStyle Font-Bold="True" BorderColor="Black" BackColor="#999999"></TitleStyle>
  <WeekendDayStyle BackColor="#FFFFCC"></WeekendDayStyle>
  <OtherMonthDayStyle ForeColor="Gray"></OtherMonthDayStyle>
 </asp:calendar></div>
<script>
function OnClick()
{
  if( divCalendar.style.display == "none")
    divCalendar.style.display = "";
  else
    divCalendar.style.display = "none";
}
</script>

The code behind is:

Public Class CalendarControl
 
Inherits System.Web.UI.UserControl
 
#Region " Web Form Designer Generated Code "
 
'This call is required by the Web Form Designer.
 
<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
 
End Sub
 
Protected WithEvents Calendar1 As System.Web.UI.WebControls.Calendar
 
Protected WithEvents txtClosed As System.Web.UI.WebControls.TextBox
 
Protected WithEvents txtIssueClosed As System.Web.UI.WebControls.TextBox
 
'NOTE: The following placeholder declaration is required by the Web Form Designer.
 
'Do not delete or move it.
 
Private designerPlaceholderDeclaration As System.Object
 
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
 
'CODEGEN: This method call is required by the Web Form Designer
 
'Do not modify it using the code editor.
 
InitializeComponent()
 
End Sub
 
#End Region
 
Private Sub Calendar1_SelectionChanged(ByVal sender As System.Object, _
 
ByVal e As System.EventArgs) Handles Calendar1.SelectionChanged
 
txtIssueClosed.Text = Format(Calendar1.SelectedDate, "dd-MMM-yy")
 
Dim div As System.Web.UI.Control = Page.FindControl("divCalendar")
 
If TypeOf div Is HtmlGenericControl Then
 
CType(div, HtmlGenericControl).Style.Add("display", "none")
 
End If
 
End Sub
 
Public Function GetClosedDate() As Date
 
GetClosedDate = txtIssueClosed.Text
 
End Function
 
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
 
End Sub
 
End Class

I want to use this Calendar Control on another aspx page. So I dragged and dropped it in an ASPX file.

Now what I do is I can click the button the calendar appears I select a date and it sets that text box (txtIssueClosed). Now on this aspx I click save to save the record into a SQL db row (table). The problem is I cannot retreive txtIssueClosed no matter what I try. I had tried to declare Protected CalendarControl as CalendarControl under the inherits section of this "logissue.aspx" page but that doesnt work. I even created a function to grab the date back in the code behind of this CalendarControl.ascx file. You see it posted as GetClosedDate...but it always returns null. I tried everything but cannot get the date from this text box to be passed in my code...

If i try

CalendarControl.GetClosedDate this always returns nothing


Please help!
Thanks,

Jon

I get an error on the 1st line of html:

Inherits="ims.jakah.com.CalendarControl"

If I remove it then it sort of works, but clicking on a date doesn't populate my text box.
Are you sure you posted all the code?

The last time I had a look at his project, the ims.jakah.com thing was causing problems too. It wasn't accepting it at all. You think the dots there are confusing vs.net?

And how is jhermiz getting it to work in the first place?

I was being a very bad boy...
Problem with those stupid ID's the other programmers are giving them...
Decided to use Get / Set:

    Public Property text() As String
        Get
            If txtIssueClosed.Text = "" Then
                Return Nothing
            Else
                Return txtIssueClosed.Text
            End If
        End Get
        Set(ByVal Value As String)
            txtIssueClosed.Text = Value
        End Set
    End Property

I'd slap someone with a soggy toad if I was you. They still using silly names?

Isn't:

If txtIssueClosed.Text = "" Then

a bit VB6'ish.

Using .NET shouldn't you do:

If txtIssueClosed.Text.Length = 0 Then

Alernatively you could create a class and inherit from a textbox and create your own function called IsEmpty.
