Solution 1

StoreNewUsers might be having decimal parameter and you're passing string, that's why you're getting error.

C#

ds.StoreNewUsers(txtFirstName.Text, txtLastName.Text, txtEmailId.Text, txtPassword.Text, decimal.Parse(txtContactNumber.Text));

Give it a try.

Solution 2

If you are sure that txtContactNumber only allows numbers and it is mandatory field then use decimal.Parse

C#

decimal contactNumber = decimal.Parse(txtContactNumber.Text);

Secondly if you are not sure about txtContactNumber value means user can provide chars or blank value then for safety use decimal.TryParse

C#

decimal contactNumber;
bool isSuccess = decimal.TryParse(txtContactNumber.Text, out contactNumber);

Please provide method definition and method call to figure out the problem. And also what exact error you are getting.

I,m unable to store my data in database when i hit submit button. It automatically creates a user defined exception & says user defined exception not handled by the user

As I told you need to provide code for method definition and method call what exactly you are passing. Secondly I have no idea what your database column data type. Provide all info to resolve the problem.
