Trigerring a search based on button

Question

Hello All,
I am new to abap webdynpro. 
I have a requirement to trigger a search for a filed based on a button click.
Once the user clicks the search button on the screen, the user should  get a window where he should be able to enter selections and a button for submitting it. The user should get the results in a table and should be able to select an entry..
Once the user slects an entry it needs to be passed back to the screen..
Can you please anyone let  me know how to achieve this..
Thanks,
Krishna

hi,
Refer SAP Online Help on OVS :
http://help.sap.com/saphelp_nw70/helpdata/en/47/9b298c66eb3376e10000000a421937/frameset.htm
Demo component : DEMO_VALUE_HELP.
Steps to create OVS :
1.Goto Your ComponentController and in properties tab add WDR_OVS
and Name the Usage Name as OVS_USAGE_1
2. In your View in Properties tab Add the Usage OVS_USAGE_1 along with InterfaceController
3. Create a Context Attribute and see the Properties of this Attributes Below.
Change the Properties
Input Help Mode : Object Value Selector
OVS Component Usage : OVS_USAGE_1
4. In Layout of the View Place an InputField and Assign the Value property to the
Context Attribute.
5. Goto Methods Tab Add a method called ON_OVS choose the Method Type as Event Handler and Enter The Event OVS automatically picked.
6. ON_OVS Method will have a parameter OVS_CALLBACK_OBJECT
It has a ovs_callback_object->phase_indicator attribute this holds different values during your Selection.
different values for phase indicator what it means you can check from the documentation and now
you can even go to WDR_TEST_OVS application and see the coding in V3 View Method ON_OVS .
In your case just fire the event on the click of button , you dont need input field and context attribute.
