Could someone please be kind enough to advise how I can add data to the grid when using datatype: “local” and when I do not want to add the data during the instantiation of the grid using the data: option?

(My goal is to create a blank grid and populate it as the user types from a local variable so obviously recreating the grid in such a scenario after every keystroke would be a bad idea)

.addJSONData() doesnt work (as this seems to be designed to work only with webservices)

So what are my options?

Thanks in advance for any help

PS: THANK YOU GUYS FOR CREATING SUCH AN AMAZING PRODUCT… (I wish we had such a fully featured grid in forms applications)

Thank you so much. I was unaware you could pass an array into that method.

One last issue I am having with is how to pass in the IDs for each row.

Passing an array of IDs to the .addRowData() method doesnt seem to work, nor does passing an ID parameter as part of the data definition. Could you advise what I might be doing wrong?

Have tried…

var data = [{

OK so for anyone interested I ended up looking at the source code and worked it out….

The first param of the addRowData method is actually the NAME of the id column in your dataset…

So basically this is how you would do it…

var data =

After all that it doesnt work. It only worked with my test data as I was using integers for my IDs in my test.

There appears to be some specialized code inside the addRowData method that (ONLY IN THE CASE OF LOCAL DATA) deletes the predefined key and sets it to the length of the data array. (I Could be wrong though – still testing where its happening exactly)

This is the code here (at least I think)

if(t.p.datatype

1
