Access System.Windows.Forms component

Hi All,

What's the different between a treeView declared like:

Code:

---

this.treeView1 = new System.Windows.Forms.TreeView();

---

and a treeNode declared like:

Code:

---

System.Windows.Forms.TreeNode treeNode10 = new System.Windows.Forms.TreeNode("Rond 1");

---

I found out how to access the TreeNode:

Code:

---

TreeNode tn1 = this.treeView1.Nodes[0];

---

But why can I access a node declared like this in a different class than the form class:

Code:

---

System.Windows.Forms.TreeNode treeNode666 = new System.Windows.Forms.TreeNode("Kalle");
treeNode666.Text = "Stig";

---

But not in the form class where the node is declared in the Form1.Designer.cs class like this:

Code:

---

System.Windows.Forms.TreeNode treeNode10 = new System.Windows.Forms.TreeNode("Rond 1");

---

And I want to access the Node I as I did above:

Code:

---

treeNode10.Text = "Stig";

---

Why does it work in the other class, but in the form class where I get 'The name 'treeNode10' does not exist in the current context' error?

Are you sure?? It is working for me, no compiler error.

Please post the whole code you are using.

This code (in Form1.cs) works:

Code:

---

private void button4_Click(object sender, EventArgs e)
{
    TreeNode tn1 = this.treeView1.Nodes[0];
    logic1.changeTreeNode(ref tn1);
}

---

This code (in Form1.cs) DOESN'T work:

Code:

---

private void button4_Click(object sender, EventArgs e)
{
    TreeNode tn1 = treeNode10;
    logik1.ÄndraTräd(ref tn1);
}

---

Where treeNode10 is declared in Form1.Designer.cs:

Code:

---

System.Windows.Forms.TreeNode treeNode10 = new System.Windows.Forms.TreeNode("Rond 1");
this.treeView1 = new System.Windows.Forms.TreeView();
this.treeView1.Nodes.AddRange(new System.Windows.Forms.TreeNode[] {treeNode10});

---

My main question is why is treeView declared as

Code:

---

this.treeView1 = new System.Windows.Forms.TreeView();

---

and treeNode10 declared as:

Code:

---

System.Windows.Forms.TreeNode treeNode10 = new System.Windows.Forms.TreeNode("Rond 1");

---

Both the treeView and the treeNode is added at designtime in designview.

Anyone?

This is NOT a declaration:

Code:

---

this.treeView1 = new System.Windows.Forms.TreeView();

---

treeNode10 is declared as a local variable, so it doesn't exist outside the method in which it's declared.
