Hi,

I follow the example in https://www.devexpress.com/Support/Center/Example/Details/E4538, but i found a problem in the sample code.

C#
protected void ASPxDataView1_CustomCallback(object sender, DevExpress.Web.ASPxClasses.CallbackEventArgsBase e) {  
        List<DataRowView> selectResult = Products.Select(DataSourceSelectArguments.Empty).Cast<DataRowView>().ToList();  
        for(int i = 0; i < selectResult.Count; i++) {  
            if(IsSuitableItem(selectResult[i])) {  
                ASPxDataView1.PageIndex = i / ASPxDataView1.PageCount;  
                return;  
            }  
        }  
    }

It is using PageCount to the calculation, but i think it is wrong, it should use page size instead, but i can't find how to get page size, can you help me on this?

Hello,

I have reviewed the example, and it works as expected, so I'm not sure what you mean by incorrect calculation. Would you please describe incorrect behavior in greater detail? You can send us a screencast illustrating how to reproduce the issue.
Anyway, if you need to get the number of items on one page, you can use the SettingsTableLayout.ColumnCount and DataViewTableLayoutSettings.RowsPerPage properties. In the case of Flow Layout, use the DataViewFlowLayoutSettings.ItemsPerPage property.

Hi Helen,
Thanks for your help.
The example work well because the page number and number of items per page is the same.
