+## 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.
