UserControl and setting text

I have a simple user control:

Code:

---

<%@ Control Language="vb" AutoEventWireup="false" Codebehind="Length.ascx.vb" Inherits="GF.Length" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
<asp:TextBox ID=txtLength Width=30px CssClass=tastFelt Runat=server></asp:TextBox>

---

I've added 10 instaces of this in my application. How do I set the text-property for each of these user controls? Let's say the content should be 5,10,15... in the text boxes.

You need to go to your code behind and add protected members for each usercontrol with the exact same name as the control on your form.

Great, thanks.
The next problem I have is how I can read the value from this user control. The user control name is Dimension and the first textbox is named txtLength1. How can I read this value, when I submit?
I have tried this:

Code:

---

sub test_calc()
  dim test as single
  test = CSng(dimension1_txtLength1.text)
end sub

---

but it doesn't work. Whats wrong?

The usercontrol will need to expose properties. For example:

Code:

---

public string TextBoxContents {
    get {
        return txtName.Text;
    }
    set {
        txtName.Text = value;
    }
}

---

Remember, a usercontrol is like a black box, it's internal data is hidden from the outside (concept of encapsulation). Only expose what needs to be exposed.

Great, just what i needed. Thanks a lot.:D

Sorry for disturbing again, but I can't make it work. Let' say my simple user control is:

Code:

---

<%@ Control Language="vb" AutoEventWireup="false" Codebehind="WebUserControl1.ascx.vb" Inherits="GF.WebUserControl1" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
<asp:TextBox ID=txtLength1 Runat=server>0</asp:TextBox>

---

How would the code be for storing the content of the textbox to a new variable?

You would need to add this to your code-behind:

Code:

---

public string Length {
    get {
        return txtLength1.Text;
    }
    set {
        txtLength1.Text = value;
    }
}

---

I am using VB.Net, I guess the code you wrote is C#. I also think there is another way: To declare the class where the user control is placed, like this, also added to the code behind:

Code:

---

protected testUserControl as ClassName.testUserControl.testUc.

---

But I can't find out how get and set the property, do you know the code in VB that I need to insert in the codebehind?

Now I've found out that I don't need to specify the classname, but what should the code be for VB instead of C#? Do you know where I can find some tutorials concerning User Controls?
