Can anyone help me out with this error?

Thanks in advance.

Hello Ruchi,

The error indicates that the value returned from the Bind("Gender") evaluation contains some different value than the initial defined options - Male and Female. This may be caused by some invalid or empty data. Can you please temporarily replace the RadioButtonList with a regular TextBox and use its Text property to set the binding expression. Thus, you will be able to check whether the returned values match as expected.

Hope this helps.
