Hello Everyone,

PRE: The grid contains several pages

PROBLEM:

1. The user navigates throught the grid and edits values on different pages

2. The user clicks "Save" button expecting to save the changes

RESULT:

Only records on the current view are saved

Here are things that I have done:

var batch = new Array();

var dataIds = $('#results-grid').jqGrid('getDataIDs');

for (var i = 0; i < dataIds.length; i++) {

var data = $('#results-grid').jqGrid('getRowData', dataIds[i]);

batch.push(data);

}

Only the current view records are retrieved. Alternatively, I tried to hash the records by getting the getGridParam('records'). This does not work either because when I try to get the record outside of the scope of the current view, using a loop, the row is undefined (getRowData(i)).

Is there a way to get all the data from the grid?

Is there a way to manually paginate?

If I use:

var gr = $('#results-grid').jqGrid('getRowData'); I only get the current view as well. It was suggested that usining getRowData, without parameters would return the entire collection but this does not work for me.

Any idea?

Hello,

This method using this way do exactley waht you want.

You should make a diffrence between client side data (this is partial data)

and server side data (this can be the whole data)

Tony,

Thanks for your response. I am doing a loadonce and paginate.

Do you think that I should be posting to the server on some sort of event handler when the user completes navigation to the next view? The data is in memory already because the control loads it from page to page and when a change is made the clientArray gets is and it remembers if the user returns to that page.

Is there a way to acces "clientArray"?

Thanks

Hello Tony,

Me again. If I add a function to jqGrid like this then I have access to the entire collection.

getJosesData:

function () {

return this[0].p.data;

then in my js file I call it like this:

var

d = $('#results-grid').jqGrid('getJosesData');

I could make it better and do it getting all ids then traverse the data... but this is not desirable. I understand your approach of doing the paging and updates on the server using the editUrl and posting. I tried to negotiate with the BA but the requirement continues to be "save once in a batch when the user clicks Save". This forces me to:

1. do a loadonce

2. cellsubmit: clientArray

The control works great if I only need to display under my requirementes, but I need to save and that is my problem.

How does JQGrid support saving the way I have mentioned?

Best Regards

Jose
