Navigating to next page on grid does not refresh the data - acumatica

Question

I have a grid that displays rows based on the form's filters. When navigated to the next page the data remains the same. I have exported the data into excel which gets all the rows. Only the first page and last page navigation change the rows. Please help on what am I missing in the ASPX

You will have to re-work the 'detailsView' delegate method so that it uses the PXView pattern to handle paging.
Detailed instructions on using PXView with Paging in delegate can be found here: https://asiablog.acumatica.com/2016/06/using-pxview-in-dataview-delegate.html
Here's the relevant code excerpt from that page:
public PXSelect<DAC> DataView;
public IEnumerable dataView()
{
PXView select = new PXView(this, true, DataView.View.BqlSelect);
Int32 totalrow = 0;
Int32 startrow = PXView.StartRow;
List<object> result = select.Select(PXView.Currents, PXView.Parameters,
PXView.Searches, PXView.SortColumns, PXView.Descendings,
PXView.Filters, ref startrow, PXView.MaximumRows, ref totalrow);
PXView.StartRow = 0;
foreach (PXResult<DAC> row in result)
{
// Do any dynamic calculations
yield return row;
}
}
Alternatively you can remove paging on the grid by setting the AllowPaging="false" property of the Grid element if you don't need paging.
