Two changes,

Form.Area= Convert.ToDouble(txtArea.Text) ;

second

when in your code behind get the value as

Form.Area.Value

Hello Garima,

To Convert Text box value to double please try below code.
```
Form.Area = Convert.ToDouble(txtTarget.Text);
```
As you mention Area as nullable, ToString() will not work. in this case you should try Convert.ToString(). or you can check String.IsNullOrEmpty(String).

Try the below code.
```
txtTarget.Text = Convert.ToString(Form.Area);
```
Also, review the below link for ToString vs Convert.ToString:

To convert a string to a double using the double.Parse() or double.TryParse() method.

Your property type is double, so you need to convert v to double.
```
Form.Area= Convert.ToDouble(v);
```
Thanks
