## Description
When a node is selected in the RadTreeView control and the Tab key is pressed, it doesn't seem to fire any of the keypress style events (down/press/up). This knowledge base article demonstrates how to capture the Tab keypress in the RadTreeView for WinForms.

## Solution
To handle the Tab keypress in RadTreeView, create a custom class that inherits from `RadTreeView` and override the `IsInputKey` method. This method checks if the pressed key is the Tab key and allows you to perform a specific action if it is.

Here is an example of how to implement this:

````C#
class MyTreeView : RadTreeView
{
public override string ThemeClassName
{
get { return typeof(RadTreeView).FullName; }
}
protected override bool IsInputKey(Keys keyData)
{
if (keyData == Keys.Tab)
{
// Perform specific action
return true;
}

return base.IsInputKey(keyData);
}
}
````

This solution is valid for controls that do not have explicit handling of the Tab key internally and for standard .NET controls as well.
