(How) Can i use the form elements of a user control from another user control???

i have a user control with 4 other user controls. Actually i have 4 panels and each user control is inside a panel. Its like a 4 page form which are all connected to each other.
Is it possible to have access to web controls that i have in my user controls from the main user control.
In my main user control i have a submit button and a tab list. User can browse through the tabs and each tab is bound to a panel. so clicking on tab1 makes panel1 visible which holds the first user control, second tab makes second panel visible and the rest invisible and the second panel holds the second user control. Each user control is made of form elements. when i click the submit button from the main user conrtol (or say web form) i want to be able to get all values from every form element i have in my user controls. Is this possible?

I can insert the actual form design in each panel but it makes the page look real complicated so i wanted to use a seperate user control for each panel. textbox1 in usercontrol2 is not defined in my main user control so i cant use textbox.text. I wonder if there is a way to inherit other  user control elements in the main one.

thanks in advance,

Try to change the elements in the user controls from protected to public like this:
public System.Web.UI.WebControls.TextBox textbox;

And declare the user controls in the main control like this:
protected WebUserControl1 webUserControl1;
protected WebUserControl2 webUserControl2;
protected WebUserControl3 webUserControl3;
protected WebUserControl4 webUserControl4;

Some words about .Net programming.

An then call the textbox1 as webusercontrol2.textbox2 right? 

Is there a way to tell visual studio to use public instead of private for every item i drop in the page? Or should i change them manual?

I did it what you said but i m getting the following error. 
Object reference not set to an instance of an object.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
usercontrol2.Label1.Text = "hello world"

End Sub

Here is more information about what i do. I have a tab control with 5 tabs. Clicking a tab makes a panel visible which holds a user control. so there is always one panel (one user control) visible in my page. I want user to browse through each tab, fill any form he wants and hit the submit button at the end. The tab,panels and the submit button is in my main page (say main.aspx). So when the user clicks submit i should have access to all textboxes, radio buttons, checkboxes in other user controls.

In the above code i tried to set the text property of label1 (in my second user control) to "hello world" but got the error.
And here are my declarations:
Protected usercontrol1 As  usercontrol1
Protected usercontrol2 As  usercontrol2

and here is how my label1 is declared in usercontrol2
Public WithEvents Label1 As System.Web.UI.WebControls.Label

Any help will greately be appreciated,

I have a web user control being used by another web user control, but the one being used will not display the labels in the resx file.
I am using DotNetNuke version 3.13 (might be 3.013) on a Window's XP machine, SP2. I have what I find to be an extremely odd situation. I have a project called TDS.Controls. This project is a web control library. Each control has its own resx file, which is located in the App_LocalResources directory. Each control inherits from Framework.UserControlBase, just like DotNetNuke's User control in DNN\Controls\User.ascx.vb. As a matter of fact, this control is doing the exact same thing I am trying to do. It is a web user control with its own resx file being used by another web user control (See ...

user control data entry form, use same codebehind as web form?
Hi All, I have a quesiton about the approach I'm taking. I have a series of report forms which I have been in the process of consolidating to a single, generic page and subs/functions in a single code-behind. All the reports can use the same set of data entry elements (a dropdown, a radio list, and a textbox). I'm trying to convert these elements to a user control. However, this user control seems to need to inherit differently than the rest of the code-behind. I've been using a single class in the code behind. Is it feasible to separate out the data entry? the code behind im...

How can a user-control know the name of the web form that uses it?
How can a user-control know the name of the web form that uses it? How can I code in the user-control access to controls of one of the web form that may use it? You reference the Parent property of the web user control in the user control code. For example, if you want to get a Button found on the web form that contains the current user control, you would put the following code in the code-behind of the user control (in C#): Button myButton = (Button)this.Parent.FindControl("myOtherControlButton"); The FindControl() method accepts the ID of the control you're ...

Can a user control communicate with another user control
I have several .ascx user controls on a page. Can they communicate with each other, or can they communicate with the page they are on? I guess I got in over my head by developing the page with user controls. Should I just remove the user controls and design the page without any? How do other people do it? Seems to me user controls are totally useless if you cannot place a value in one from another, or from the main page. You can create public properties in user controls, as with any other construct.  Give the UC an ID in the page, and the page can manipulate those public properties.As...
