Visual Studio 2022 - working with 'InvalidOperationException' with Custom User Control in WinForms App
I'm having trouble with I'm trying to figure out I've searched everywhere and can't find a clear answer. I'm currently developing a WinForms application in Visual Studio 2022 and running into an scenario when trying to use a custom user control... The control is designed to display data from a database, and it seems to work fine during development. However, when I try to load this user control dynamically at runtime, I encounter the following behavior: ``` System.InvalidOperationException: 'Invoke or BeginInvoke want to be called on a control until the window handle has been created.' ``` I've checked that the user control is indeed being instantiated correctly, and I ensure I'm not trying to access any UI components before the form is fully loaded. Here's a snippet of the code where I'm trying to load the control: ```csharp private void Form1_Load(object sender, EventArgs e) { MyCustomControl myControl = new MyCustomControl(); this.Controls.Add(myControl); myControl.DataSource = myDataSource; myControl.Dock = DockStyle.Fill; myControl.LoadData(); // This is causing the exception } ``` The `LoadData` method of `MyCustomControl` is trying to access some properties of the control that depend on the handle being created. I've tried using `BeginInvoke` to defer the loading, but that doesn't seem to resolve the scenario either. I also made sure that the data source is not null before I set it. Any suggestions on how to properly handle the loading of a user control in a WinForms app, especially when it involves data binding? Is there a recommended practice to ensure that all UI components are fully initialized before manipulating them? This is part of a larger service I'm building. This is part of a larger API I'm building. What am I doing wrong? Any feedback is welcome! Has anyone dealt with something similar?
