Which version of ExtJS are you using?

I am doing everything with ext designer

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

Code:

---

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



thanks

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:

Code:

---

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

---

It will create the record for you from the model.

Hi,
I think it created the record but it is still not updating the grid.
Please help me out

thanks

How are you checking that the record has been added?

Are there any error messages?

Do the fields in the data map properly onto the fields in the model? Note that they will not be run through the reader.

Can you post the configs for your model, store, grid, etc.? Even better, a complete, minimal test case would be ideal.

Can you confirm you're having this problem in multiple browsers?

Sorry My mistake,
Now it is adding record in the store + the grid
but it is adding at the end of the grid,
is it possible to add it as first record on the grid (I mean in the first position)
That will be really nice
if it can be done thanks

Use insert() with an index of 0 instead of add().
