I have a wired issue related to custom property in Visual WebPart where the custom property is shown properly and already holds a value when editing the web part properties, but when calling the custom property value in code-behind it always returns NULL?

Anyone can help me to solve this problem and guide me How can I use custom property in Visual WebPart without returning a NULL value.
