Setting label text = textbox text on other form

How can I set the text of a label on a user control equal to whatever the user types into a textbox on a .aspx file?

Is there any easy way of referencing the label in the .ascx file?Create a property in the user control

public property Text {
get { return label1.text }
set { label1.text = value; }
}

the property changes the value.

Hi !!

Is that code will make the label text as same as the textbox text on runtime like filling a textbox with some text amd click on button (as example) then i see the text of the label is what i typed in the box. Is that really the benefit of this code. If there is a different idea or i got that wrong please advise!! Thanks
Thanks for that.

Can you tell me if that should be in the .ascx file or the .ascx.vb file?

Will this work for setting the user control label text = text box on another form?
I think this is what you are looking for. If you are using code-behind, always put code in the code-behind (the .vb or .cs file); otherwise, you have no choice to put it in the .ascx file.

Brian
The property exposes a field in the user control without providing direct control, so if you want to encode the text or do something else to it (like trim it), you can.

Brian
This is what I have done so far

In the .ascx.vb class I have added the folowing class:

Public Class Logon
 Inherits System.Web.UI.UserControl
 Private username As String
 Public Property Name() As String
 Get
 Return username
 End Get
 Set(ByVal Value As String)
 username = Value
 End Set
 End Property
End Class

and within .aspx.vb file I have added this:

<ACME:GETEST id="GETEST1" runat="server" username="xyz" OnNavigate="TestControl_OnNavigate"></ACME:GETEST

And this is where the label I want to set the text on is declared in the codebehind file of the usercontrol.

Public MustInherit Class WebUserControl1
 Protected WithEvents lblUser As System.Web.UI.WebControls.Label

Now how do I actually set the text of the label - how do I call the class?
I'm a little confused of the layout. If Logon is your user control code-behind page, and you have the lblUser label within that user control (in the .ascx), then put the Protected WithEvents statement for the lblUser in the Logon code-behind, and do:

Public Property Name() As String

Get

Return lblUser.Text

End Get

Set(ByVal Value As String)

lblUser.Text = Value

End Set

End Property

Brian
Heres the file named GENav.ascx.vb:

Public MustInherit Class WebUserControl1
 Inherits System.Web.UI.UserControl
 Protected WithEvents lblUser As System.Web.UI.WebControls.Label
#Region " Web Form Designer Generated Code "
 'This call is required by the Web Form Designer.
 <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
 End Sub
 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 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
'Other code ...
Public Class Logon
 Inherits System.Web.UI.UserControl
 Protected WithEvents lblUser As System.Web.UI.WebControls.Label
 Private username As String
 Public Property Name() As String
 Get
 Return username
 End Get
 Set(ByVal Value As String)
 username = Value
 End Set
 End Property
End Class

And the textbox is in an .aspx file.

When the user clicks a button to Logon, I want their Logon name entered in the textbox to appear on the label lblUser in the User Control.

Im just not sure how to call the Public Property Name() As String part and to use what the user entered in the textbox.
What do you use this for: WebUserControl1? You don't have anything inheriting from it (as you declared it MustInherit). Also, a user control class that inherits from this cannot define controls in the base, and inherit them in that way. You need to define all of the controls in the Logon user control, and each control must have a Protected WithEvents declaration in the code-behind.

Whenever the login button is clicked, then you make that assignment. Is the lblUser label in the same user control as login, or are we talking about a different user control (the first one)? I'm confused..

Brian
There is only one user control this is where the lblUser label is.

WebUserControl1 was code I didnt write - added by the system and I dont really know what its for but it was working fine so I just went with it.

The button I want to do the assignment of the textbox text to the label is just in a .aspx file so its on a web form.

I added the code in the Logon class below trying to do what you said earlier so the Logon class didnt exist before this.

Public Class Logon
 Inherits System.Web.UI.UserControl
 Protected WithEvents lblUser As System.Web.UI.WebControls.Label
 Private username As String
 Public Property Name() As String
 Get
 Return username
 End Get
 Set(ByVal Value As String)
 username = Value
 End Set
 End Property
End Class

SO if the button is in the user control, you need a Protected WithEvents definition for that too; that should be generated by VS.NET if you are using that; are you? If you have that to, for the link button's click event, then if the user logs in, assign the user name text in the textbox (also needing a protected withevents statement) to the label. You wouldn't need the property if you didn't want to, or could use it as readonly to state what the username was. I wouldn't assign the value to a string, but would assign it directly to the label.

Brian
Also in continuing, it may help to post the entire .ascx.cs file for login control and the entire HTML code .ascx. Leave out the other code that you aren't using; that's generated by the .NET editor.

Brian
The button is not in the user control it is in the web form.
Yes I am using VS.NET.

Here is all the code as it was before I started trying to assign the textbox to label text:
GENav.ascx.vb file:

Public MustInherit Class WebUserControl1

#End Region
 Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Can you see what I am trying to achieve a bit clearer now?
i will assume the following, correct me if i'm wrong.

1) you have an aspx page with a textbox and a button and a usercontrol containing a label
2) the user enters a name, and clicks submit, the page then does a postback
3) the usercontrol label changes to the textbox text.

to do this...

1) add this to the aspx page

Protected WithEvents m_UserControl As WebUserControl1 (your control type)

2) in design view of the aspx page, click the button and add the following code.. change the findcontrol string to the name of the control in the TagName attribute at the top of the aspx page.

m_UserControl= CType(FindControl("Webusercontrol11"), WebUserControl1)
m_UserControl.TextValue = txtname.Text

this should do what you need.

i think it has all been said in the post earlier, but it looks like things got confusing.
