Hello,
I would like to ask you if the following scenario can be solved with AJAX functionality:
I have web grid (table) and each row contains delete action. When user clicks on delete icon then table row should be deleted, ideally without page refresh but only with web grid refresh (AJAX).
My current solution is over action listener. It works fine but the whole page must be refreshed.
<h:commandButton image="images/icon_remove.gif" value="#{DATA_ROW.id}" actionListener="#{assetController.removeAssetGroupListener}" />
It would be nice to have a NetAdvantage commands with AJAX support.
Thank you,
ANECT
Great, it's what I have been searching for! (btw: I haven't found it in documentation)
And (I hope) last question - I need transfer item's id, something like the following:
<ig:link iconUrl="images/icon_remove.gif" value="#{DATA_ROW.id}" smartRefreshIds="groupMembershipTable" actionListener="#{assetController.removeAssetGroupListener}" /> But this solution has one disadvantage -ther aree image and value on the screen. Is there elegant way how transfer params via link?
Thank you very much!
Hi, Anect!
<ig:link value="Delete" smartRefreshIds="grid" actionListener="#{webGridSelectionBean.onPressDelete}"></ig:link>
tag. Don't forget to apply a value to the smartRefreshIds attribute since only in that case only the mentioned components will refresh and not the whole page.
Regards!
But problem is that when user clicks on command then form data is submitted to the server and then action listener is processed. And if I would like to change web grid's data only (without page refresh) then I need to have different way how to do it.
Thank you for reply.

Hi, ANECT!
It seems like you have to add grid.dataBind(); into your action listener, where grid is a com.infragistics.faces.grid.component.GridView property in the backing bean and your WebGrid is binded to it. When the dataBind() method is executed it will reconnect the grid to it's data source and the grid will refresh without the need of the whole page to be refreshed.
