C# - Get The Set / Real Value Of The Visible Property?

The Get of the Visible property of a control recursively looks up the tree to indicate if the control will be rendered or not.

I need a way to see what the "local" visible value of a control is regardless of what its parent controls are set to. i.e. Whether it itself was set to true or false.

I have seen this question, How to get the "real" value of the Visible property? which uses Reflection to obtain the local state, however, I have not been able to get this working for WebControls. It's also a rather dirty method of getting the value.

I have come up with the following extension method. It works by removing the control from its parent, checking the property, then putting the control back where it found it.

public static bool LocalVisible(this Control control)
{
//Get a reference to the parent
Control parent = control.Parent;
//Find where in the parent the control is.

[Code]....

Is this an acceptable way of doing this? It works fine and I haven't come across any performance issues. It just seems extremely dirty and I have no doubt there could be instances in which it might fail (for example, when actually rendering).
