How Can I Efficiently Assign Values to Sequentially Numbered Textboxes in a WinForms Application?

Iterative Assignment of Values to Textboxes on WinForms

In a WinForms application, assigning values to numerous sequentially numbered textboxes can be challenging. To simplify this process, consider the following approach:

1. Recursive Control Retrieval: Utilize an extension method, "GetChildControls," to recursively retrieve all controls and sub-controls of a specified type.

public static IEnumerable<TControl> GetChildControls<TControl>(this Control control) where TControl : Control
{
    var children = control.Controls?.OfType<TControl>() ?? Enumerable.Empty<TControl>();
    return children.SelectMany(c => GetChildControls<TControl>(c)).Concat(children);
}

2. Textbox Iteration: Employ the "GetChildControls" method to obtain all textboxes within the form.

var allTextBoxes = this.GetChildControls<TextBox>();

3. Textbox Assignment: Iterate through the collection of textboxes, assigning values based on the "i" loop counter.

foreach (TextBox tb in allTextBoxes)
{
    tb.Text = ...;
}

This approach effectively iterates through textboxes scattered across multiple panels, simplifying assignment tasks and enhancing code maintainability.
