WinForms: How to continues User Input in a Form with Dynamic Controls on Re-Loading
I'm dealing with I've been struggling with this for a few days now and could really use some help... I am developing a WinForms application using .NET Framework 4.8 where I dynamically add controls to a form based on user selection. However, I am working with an scenario where the input values from the controls are lost when I reload the form. I want to continue the user input so that when they navigate back to the form, their previous inputs are retained. The controls are added to a `Panel` inside the form. Here's a simplified version of the code I am using to add the controls: ```csharp private void AddDynamicControls(Dictionary<string, string> userInputs) { panel.Controls.Clear(); // Clear existing controls foreach (var entry in userInputs) { var textBox = new TextBox { Name = entry.Key, Text = entry.Value, Width = 200 }; panel.Controls.Add(textBox); } } ``` The user inputs are stored in a dictionary, but when I call `AddDynamicControls(userInputs)` after the form is reloaded, the `TextBox` values do not reflect the previous inputs. Instead, they show up empty. I have also tried using the `Load` event of the form to call this method, but it doesn't seem to work as expected. Moreover, I am getting a NullReferenceException if I attempt to access the `userInputs` dictionary and it hasn't been initialized before calling it. Here’s the relevant part of my code where I am trying to handle loading the inputs: ```csharp private void MyForm_Load(object sender, EventArgs e) { if (userInputs != null) { AddDynamicControls(userInputs); } else { userInputs = new Dictionary<string, string>(); // Initialize if null } } ``` Can anyone guide to understand how I can keep the user input values intact when navigating back to the form? Are there best practices for handling dynamic controls in WinForms to avoid losing user input across sessions?
