Title: How to refresh a browse cell using Ajax
Post by: Alberto on August 15, 2020, 07:17:26 AM

Hi, Im trying to refresh a browse cell using ajax.
I can GET the value from the server but the problem is how to identify the id of the cell I must update.
In the attached pic you can see CVH in column 1 , using it I ask the server its price that I need to update in column 4
To update the price I need to know the cell id.
The ids seams to be divxxxxxxx_div where xxxxxxxx is a random number.
Is there any way to set the ids a different way so I can have a relation between CVH and its price cell?
Thanks

Hi,

I cannot see your picture. But i know what you are trying to do.

The best way to generate the contents of a cell in a browse is to use the original browse to do it. Then you don't need to know the div id as the browser knows it.

DO value::YourFieldName

Will do it. I expect you'll need to pass an event to the browse to get it to refresh the value for you.

I'd suggest creating a simple browse and utilise the existing fresh cell option to check what events are passed. Once you see that, you can do the same thing.

Regards
Bill

Thanks bshields, here goes the picture, I dont want to refresh all the browse, it can be done using NetRefresh and works ok but it is slow.
May be I dont understand what you mean because there are many ::YourFieldName, one per row.

Hi,

You can refresh only a cell. Each uniquely named div can be refreshed independently.

The code that generates the contents of the cell is DO value::YourFieldName.

You just have to watch how NT does it and do the same.

I've attached a screen cap of the place where NT does it.

This is the function to know the id

p_web.DivHeader('bCotizaciones_Cot:Ultimo_'&Cot:ID,'',net:crc,,loc:extra)

where bCotizaciones is the browse name, Cot:Ulitmo is the name of the column field and Cot:Id the Id of the row record

The result is like:

<div id="div690197848_div" >

Then, I know the id to modify via javascript
