var RecToUp = Ext.getCmp("transGridId").getStore().recordType;
									var r = new RecToUp({
								 	T10F2: this.Trans_key,
								    T6F2: this.NameKey,
								     }); 
									r.commit();

Which version of ExtJS are you using?

[sajan]

I am doing everything with ext designer

the ext version is ext-4.0.2a.
I also tried

var ObjectRecordType = Ext.data.Record.create(['T10F2', 'T6F2' ]);									var rec = new ObjectRecordType({
									T10F2: thisTrans_key,
								  	T6F2: "ram"});

Ext.getCmp("transGridId").store.add(rec);

but this is also not working.
I dont want to reload my store all the time to refresh the grid so please do helo me

Please indent your code so that it is readable before you post it.

You don't need to create the record yourself. You can just do something like this:

Ext.getCmp("transGridId").getStore().add({
    T10F2: this.Trans_key,
    T6F2: this.NameKey
});

It will create the record for you from the model.
