Hi,

It’s Infragistics policy to not pre-announce features until they have gone through QA cycle and are marked
for release so we can't give you specifics on dates. However, this is a feature that has been requested before and
is in our list of features to consider for feature releases. The implementation of the feature in upcoming releases
depends on the number of customer requests logged at http://devcenter.infragistics.com/Protected/RequestFeature.aspx
so one more customer vote will move it up in the priority list.

Best Regards,
Yanko

I already have a request opento include native paging feature in XamDataGrid. We have a use case of displaying a lot of data on the page in a hierarchical fashion with paging enabled at all the levels.. i.e. lets say you have customers and then it has child records from Order tables then one should be able to page through both customer and order. Do you have any updates on this, like when this feature could be delivered?

Thanks,

Maulik.

Hi Karine -

There are no events fired in response to the activities you mentioned.

However, one way to achieve a data paging scenario is to use a WindowsForms control included in NetAdvantage called UltraDataSource, as the DataSource for your xamDataGrid. The UltraDataSource control supports virtualized data sourcing using a callback mechanism. Since, by default, the xamDataGrid only asks for data as it needs it (for example when the user 'pages down' to reveal the next page of records), the UltraDataSource virtual mode works perfectly with the xamDataGrid.

When the xamDataGrid needs more data, it goes to the data source (in this case the UltraDataSource), and says 'give me another record'. The UltraDataSource will fire an event that you can handle to initialize the requested record.

Hi,

I would like to try to perform paging by my self. Is there an event exposed that would enable me to trap the moment the user reachs the first or last item of the list when scrolling in the list? Is there an event exposed that trap the header click event?

Tanks
