Hi,@Fiona. Welcome Microsoft Q&A.

To dispose of resources defined in a user control, you can override the Dispose(bool disposing) method in the user control's code-behind file (the designer.cs file) and add your disposal code there.

protected override void Dispose(bool disposing)
{
    if (disposing && (components != null))
    {
        DisposeResources();
        components.Dispose();
    }
    base.Dispose(disposing);
}

private void DisposeResources()
{
    // Dispose of your resources here
}

By separating the disposal logic into the DisposeResources() method, you could call it from the Dispose(bool disposing) method to properly dispose of your resources.

It's generally recommended not to modify the designer.cs file manually, as it is automatically generated and can be overwritten if the designer file is regenerated. Instead, make the modification in the code-behind file of the user control (*.cs file) to ensure that your changes are preserved.

By adding the disposal code within the Dispose method, you ensure that the resources are properly disposed of when the user control is no longer needed.
