8 Mar 2012, 10:39 PM
well i am trying to improve my self in extjs , now what i want to do is , i have a grid , a button and a textbox , now i want that after writing the recid in textbox and pressing the button my grid will show all the records of that id , or you can say i want to show conditional records in my grid , for this i have to send parameter to my webservice (i am using asp.net/c#) , so that i can get the filtered records , someone tell me that i have to send the parameters through store , and someone tell me that i have to send the parameters in the buttons handler event by using the post method and after that reload the store , but i tried both methods and i failed .

please guide me and help me , because you people are more experienced in it and all of you are my teachers..

If all your records are loaded in the store, you can use filters (filtering on the client side):

Ext.create('Ext.util.Filter', {property: "recid", value: textbox.getValue(), root: 'data'}),

you migh need some records that are not loaded in the store, you can do this..
and then filter the store on the server with the given parameter

params : {
recid : textfield.getValue();

you can use a config remoteFilter on the store. Then it uses the same api (filter function on store for the filtering) and therefor its sending a filter parameter to the server (a hash with property value).
