I need a program to control my stepper motor. Can you please let me know if you can help me.
I haven't used LabView before. The data card I am using is NI 9215. and using the following stepper motor:

I need to control the steps (the motor has micro-step function) and the direction of the motor. Help required urgently.
Thanks a lot in advance

Urgent or not, if you are using the USB-9215, you have big problems since the 9215 does not have any outputs that you can use for controlling the stepper.

What Do I need to use? How do I go about it ?

Have you read the product sheet? You can control it with pulses, general I/O, or RS-485. For the first two, a device with a counter output or hardware timed digital I/O might work. The RS-485 requires either a RS-232->RS-485 converter or direct RS-485 device for the pc.
Click on the Products & Services link at the top of the page and you can search for hardware your lab may have. If you need to buy something, I suspect the RS-485 route would be the cheapest. NI's costs $149 but you can probably find something for much less.

uh... no
As Dennis plainly stated, you need a digital pulse train output and/or digital IO or RS-485
Neither the USB 9215 nor the USB 9263 have these feeatures
Easiest method will probably be using RS-485 to send commands to the built-in motor driver.
Call NI and talk to an application engineer for help if you don't understand the data sheets

What if I amonly looking for control using command pulses? As that option gives me 16 types of resolution for my step angle selection.

Your ability to control the motor with RS485 is almost certainly equal to using pulses. Read the manual.
If you insist on using pulses, then find a board with a counter output or digital output. In theory, you can also use an analog output if you are able to rewrite the existing code examples that use a counter/digital I/O. If you are up to that task, go for it.

Stepper motor with built in driver/controller
You can try UIM stepper motor driver/stepper motor controller
