Custom property is always null in Visual WebPart

Question

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.

Why Custom property is always returned null in Visual WebPart?

Looks like you are using Visual WebPart (Farm Solution only) that needs different configurations to implement custom property.

To configure custom property in Visual WebPart (Farm Solution only) in a correct way, you have to do the following:

1. In your Visual WebPart, Open the "CS" file, and under the class definition add your Property definition.
2. Go back to open the ".ascx.cs"

3. Below the class definition, create a new instance from the class name that was used in the "CS" file.

    public ContactForm contactform { get; set; }
   

4. Again, go back to "CS" file. file, and at CreateChildControls() function, add the below code
   

5. To get the property value in the "ascx.cs", you have to do the following:
