C# Logic failure in dynamic Controls Code

Question

I am pretty new to programming, so please do not hate me for dirty code. I would love to get beginner friendly tips if you have some for me. And sorry for my english I hope you can understand me and maybe try my code yourself to see my problem in action.

I have a Windows form with a group box, in the group box is a panel. Directly in the Form there is a Button to add a row with a set of Controls (in my case 1 row has 2 buttons. One without sense now and one to delete the row) into the panel.

The buttons in one row should have the same tags (1-X)

So adding a row with my 2 button-set works "fine". My next plan was to delete the row when i press the delete button from a row.

After Deletion of a row which i identify with Control Tags, I want to decrease the Number Values for Name (Function 2 to Function 1 if I delete the row 1 for example), Tag and Text from each button which has a higher Tag Value than the row number which got deleted. So theres the failure somewhere I guess.

It's working fine to Add and Remove. But not if i want to add a row again. I must click multiple times then to add a new row.

To explain what I want to do:

|ADD ROW BUTTON| //Clicked 4 Times already

PANEL
{
|Function 1| --- |Delete 1|
|Function 2| --- |Delete 2|
|Function 3| --- |Delete 3|
|Function 4| --- |Delete 4|
}



// Clicking |Delte 2|
// Removed Row 2 and rename those which have bigger Row number as the deleted row with decreased value for the Text, Tag & Name
// So row 2 gets removed, Function 3 becomes Function 2 and Function 4 becomes Function 3

PANEL
{
|Function 1| --- |Delete 1|
|Function 2| --- |Delete 2|
|Function 3| --- |Delete 3|
}

 

But they mostly "never" rename like i've planned in my code/mind. Only sometimes when "playing" with it it will rename a button

My Code looks like this (start with a Winform with a panel named pnl and the Row AddButton):

public partial class Form1 : Form
{
    int rowCount = 0;
    int lastY;

    public Form1()
    {
        InitializeComponent();
    }

    private void btnAdd_Click(object sender, EventArgs e)
    {
        AddRow();
    }

    public void AddRow()
    {
        rowCount++;
        label1.Text = rowCount.ToString();
        #region Create the Function Button in a row
        Button btnFunction = new Button();
        if (rowCount == 1)
        {
            btnFunction.Location = new Point(10, 5);
        }
        else if (rowCount > 1)
        {
            Control[] letztesY = pnl.Controls.Find($"btnFunction{rowCount - 1}", true);

            foreach (var button in letztesY)
            {
                lastY = button.Location.Y;

            }
            btnFunction.Location = new Point(10, lastY + 25);
        }
        else
        {
            MessageBox.Show("Unerwarteter Fehler");
        }

        btnFunction.Name = "btnFunction" + rowCount;
        btnFunction.Tag = rowCount;
        btnFunction.Text = "Function " + rowCount.ToString();
        pnl.Controls.Add(btnFunction);
        #endregion

        #region Create the Delete Row Button in a row
        Button btnDelete = new Button();
        if (rowCount == 1)
        {
            btnDelete.Location = new Point(85, 5);
        }
        else if (rowCount > 1)
        {
            Control[] letztesY = pnl.Controls.Find($"btnDelete{rowCount - 1}", true);

            foreach (var button in letztesY)
            {
                lastY = button.Location.Y;

            }
            btnDelete.Location = new Point(85, lastY + 25);
        }
        else
        {
            MessageBox.Show("Fail");
        }

        btnDelete.Name = "btnDelete" + rowCount;
        btnDelete.Tag = rowCount;
        btnDelete.Text = "Delete " + rowCount.ToString();
        btnDelete.Click += new EventHandler(deleteCallerRow);
        pnl.Controls.Add(btnDelete);
        #endregion

    }

    private void deleteCallerRow(object sender, EventArgs e)
    {
        rowCount--;
        label1.Text = rowCount.ToString();

        Button delCaller = sender as Button;

        #region DeltePressedRowDelButton
        Control[] toBeRemovedDelButtons = pnl.Controls.Find($"btnDelete{delCaller.Tag}", true);
        foreach (var delBtn in toBeRemovedDelButtons)
        {
            pnl.Controls.Remove(delBtn);
            delBtn.Dispose();

        }

        Control[] toBeRemovedFunctionButtons = pnl.Controls.Find($"btnFunction{delCaller.Tag}", true);
        foreach (var funcBtn in toBeRemovedFunctionButtons)
        {
            pnl.Controls.Remove(funcBtn);
            funcBtn.Dispose();

        }
        #endregion

        #region Decrease Numbers in Buttons Texts, Tags and Names
        Control[] toBeRenamedDeleteButtons = pnl.Controls.Find($"btnDelete", true);
        foreach (var db in toBeRenamedDeleteButtons)
        {
            if (Convert.ToInt32(db.Tag) > Convert.ToInt32(delCaller.Tag) )
            {
                db.Name = "btnDelete" + Convert.ToString(Convert.ToInt32(db.Tag) - 1);
                db.Tag = Convert.ToInt32(db.Tag) - 1;
                db.Text = "Delete " + Convert.ToString(Convert.ToInt32(db.Tag) - 1);
            }
        }

        Control[] toBeRenamedFunctionButtons = pnl.Controls.Find($"btnFunction", true);
        foreach (var fb in toBeRenamedFunctionButtons)
        {
            if (Convert.ToInt32(fb.Tag) > Convert.ToInt32(delCaller.Tag))
            {
                fb.Name = "btnFunction" + Convert.ToString(Convert.ToInt32(fb.Tag) - 1);
                fb.Tag = Convert.ToInt32(fb.Tag) - 1;
                fb.Text = "Function " + Convert.ToString(Convert.ToInt32(fb.Tag) - 1);
            }

        }
        #endregion


    }
}

 

 If i alwas remove the last row, also multiple times, the rowCount works also when adding and loop this procedere. But if i delete some rows between and addin some new ones, the rowCounter is not true anymore.

I didn't handle free spaces between rows when removing one now since I am stucking at the Problem with the Renaming/Count doesn't work as expected.

Thanks for any help in advice.

Hope you can understand my problem.
