I am working on an ASP.NET application and I am creating a LINQ query which will select paginated records from db. on user interface I have a listbox where user can select multiple choices. I want to know:
How can I increment Skip(), Take() parameters to view next results ?
How can I use "IN" key word so that if user selects multiple options from listbox, query can check all values ?
My query looks like this:
var searchResults = context.data_vault.Where(d => d.STATE == lstStates.SelectedItem.Text).OrderBy(d= > d.dv_id).Take(10).Skip(2); GridView1.DataSource = searchResults; GridView1.DataBind();
I think you are using Skip incorrectly. It should be before the Take.
Skip skips a number of records, so for your first page, pass in 0, else pass in the (page number - 1) * records per page.
I usually do something like this:
int Page = 1; int RecordsPerPage = 10; var q = yourQuery.Skip((Page - 1) * RecordsPerPage).Take(RecordsPerPage);
