Good afternoon! In a situation wherein a single page will contain multiple paging such as displaying master-details records or similar requirements, using a couple or more PagedList pager will cause logical errors such as when you click on the paging of details record to traverse to the next page, the paging of master record will move to the next record as well. In order to solve this dilemma, we need to assign a specific page variable to a PagedList object to prevent this issue from happening. In this example, I'll demonstrate showing products information from AdventureWorks database whose stocks are above or below a certain reorder point. The page model class below has two page properties namely BelowReorderPage and AboveReorderPage . And these properties are assigned to their specific PagedList object whether ProductsBelowReorder or ProductsAboveReorder . PageModel.cs public class PageModel { public int BelowReorderPage { get ; set ; } public int AboveReorderPage {

Here's an example ASP.NET MVC application that shows information in a DataList layout with pagination using PagedList Pager. The project also integrates Bootstrap for enhancing the UI and display the images from AdventureWorks Products table through an ImageHandler class. The significant files used in this project are: 1. PagingModel.cs/IndexModel.cs - These classes are responsible for defining the page number, size of page, and PagedList property that stores the information that are paged accordingly to it's size. public class PagingModel { public PagingModel () { Size = 24 ; Page = 1 ; } public int Page { get ; set ; } public int Size { get ; set ; } } public class IndexModel { public PagingModel PageModel { get ; set ; } public IndexModel (PagingModel pageModel) { Products = new PagedList<ProductViewModel>( new List<ProductViewModel>(), 1 , pageModel.Size); PageModel = pageModel; } public IPagedList<ProductViewModel>

Basing from the post DataTable With Running Total Per Group which applies running total to a DataTable object, we can also achieve the same functionality through the front-end side by changing the structure of the GridView control given that this is an ASP.NET WebForm application. The snippet to set the control's data source is simple such as below: dt.Columns.AddRange( new DataColumn[ 5 ] { new DataColumn( "SrNo" , typeof ( int )), new DataColumn ( "PartyName" , typeof ( string )), new DataColumn ( "ItemName" , typeof ( string )), new DataColumn ( "ChqAmt" , typeof ( int )), new DataColumn ( "PartyCode" , typeof ( string ))}); dt.Rows.Add( 1 , "ABC Water Supply" , "Construction Service" , 400 , "ABC" ); dt.Rows.Add( 2 , "ABC Pump Services" , "Type 24 Engine Pump" , 150 , "ABC" ); dt.Rows.Add( 3 , "ABC Water Supply" , "12 Ft Wa

Good Evening! There was a question raised by a developer if it's possible to compute the running total of a specific DataTable column per grouping or category. The solution is to mark the category as a flag variable that indicates the group to be calculated. The sample code below creates a DataTable object with fictitious information of hardware materials that belong to a particular group specifically PartyCode column. If a column belongs to that group, it will perform calculations. If not, reset the flag variable and total so as to perform new calculations. When computing totals for large number of records, make sure to sort the DataTable using it's category. DataTable dt = new DataTable(); dt.Columns.AddRange( new DataColumn[ 5 ] { new DataColumn( "SrNo" , typeof ( int )), new DataColumn ( "PartyName" , typeof ( string )), new DataColumn ( "ItemName" , typeof ( string )), new DataColumn ( "ChqAmt" , typeof ( int

Good day! I was trying to apply integrate an Image HttpHandler that discourages leeching from one of my Web Forms project to ASP.NET MVC. This hack is found on ASP.NET 2.0 MVP Hacks site. Upon running the ASP.NET MVC project, an issue was thrown to the browser specifically "HTTP Error 500.23 - Internal Server Error. An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode." Upon investigating, I found out that handlers in WebForms are declared in <httpHandlers> under <system.web>. <system.web> <httpHandlers> <add verb= "*" path= "*.jpg" type= "Events.Web.Extensions.NoLeechImageHandler" /> <add verb= "*" path= "*.jpeg" type= "Events.Web.Extensions.NoLeechImageHandler" /> <add verb= "*" path= "*.gif" type= "Events.Web.Extensions.NoLeechImageHandler" /> <add verb= "*" path=

To hide a BoundField column but make it's value still accessible through JavaScript just set column's ItemStyle-CssClass and HeaderStyle-CssClass properties using CSS class with value display:none . CSS .hiddenColumn { display : none ; } ASPX <asp:BoundField DataField= "GroupCode" HeaderText= "Group Code" ItemStyle-CssClass= "hiddenColumn" HeaderStyle-CssClass= "hiddenColumn" />
