            {

                TextBox textbox = new TextBox();
                textbox.Text = folderBrowserDialog1.SelectedPath;

        {
            int count = panel1.Controls.OfType<Label>().ToList().Count;
            TextBox textbox = new TextBox();
            count = panel1.Controls.OfType<TextBox>().ToList().Count;
            textbox.Location = new Point(3, 25 * count);
            textbox.Size = new Size(188, 20);
            textbox.Name = "textbox_" + (count + 1);
            textbox.TextChanged += new System.EventHandler(this.TextBox_Changed);
            panel1.Controls.Add(textbox);

            Button button = new Button();
            //count = panel1.Controls.OfType<Button>().ToList().Count;
            button.Location = new Point(207, 25 * count);
            button.Size = new Size(75, 23);
            button.Name = "button_" + (count + 1);
            button.Text = "Browse " + (count + 1);
            button.Click += new System.EventHandler(this.btnBrowse_Click);
            panel1.Controls.Add(button);
        }

Hi Ankit,

The textbox in the btnAdd_Click() event is not the same as the textbox in ChooseFolder() method. That is, the textbox in ChooseFolder() method is being instantiated and storing the value, but as soon as it gets out of the method, it perishes. So it doesn't store the value in the btnAdd_Click() event as that textbox is totally unaware of the other textbox.

I guess your business logic is:

1) Store the value of the path on 'Browse' button click.
2) Create array of controls and add the path in the textbox on 'Add' button click.

If this is the case, then the following changes will do.

C#

string TextBoxValue = "";
public void ChooseFolder()
{
    FolderBrowserDialog folderBrowserDialog1 = new FolderBrowserDialog();
    if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)
        TextBoxValue = folderBrowserDialog1.SelectedPath;   // Storing the value in a temporary string.
}

Then add the line as indicated in the code below.

C#

private void btnAdd_Click(object sender, EventArgs e)
{
    int count = panel1.Controls.OfType<Label>().ToList().Count;
    TextBox textbox = new TextBox();
    count = panel1.Controls.OfType<TextBox>().ToList().Count;
    textbox.Location = new Point(3, 25 * count);
    textbox.Size = new Size(188, 20);
    textbox.Name = "textbox_" + (count + 1);
    textbox.Text = TextBoxValue;    // This line was added.
    textbox.TextChanged += new System.EventHandler(this.TextBox_Changed);
    ...............................
    ...............................

I hope that will solve the problem.
