I am curious as to what people would thing is the best way to implement this. On my overview page, I have a data grid which is sortable and has custom filtering written for it. When you click on an item in the grid, it loads a separate page with details. I would like to implement result paging through on the detail page keeping in the same order as the previous page data grid. Now I've thought of a few ways to do this:
Change the link to be a postback and handle the sort order programatically Sort filter and sort settings on application of the settings in the session Pass the filter and sort settings on the query string to the detail page. None of these seem very clean to me, and option 3 is the only cogent option I've thought of. Am I missing something? Is there a more elegant way to do this?
I'm trying to setup is a News module with article listing paging and article detail paging. I have a GridView with paging that lists my articles just fine. In that list, some article titles have links that direct to an article detail page by passing in the articleID to the details page. I was able to setup my details page, which uses a DetailsView control, to use paging by using an ObjectDataSource with pageIndex and pageSize parameters from the querystring. Once on my detail page, I can use my navigation arrows to move through Next and Previous articles just fine.
No matter which article I click in my article list, my detail page always starts with pageIndex 0 and thus not the article I clicked on. I understand why that is because it's going by pageIndex value instead of articleID. What I need it to do is, set the detail to whatever articleID i pass in, then allow me to navigate Next and Previous to THAT particular article instead of starting me off from pageIndex 0.
I have a Page with a FileUpload control on the top with the "Insert" button, in order to insert pictures Below that, i have a Listview showing all the pics. THis is the way i am placing my Update Panel:
[Code]....
How can i, press the INSERT button and reloads only the Content Template after INSERTING?
I'd like to implement a custom paging template for my formview that displays numeric paging as well as next/previous buttons. The pre-defined templates only appear to have numeric first last as an option. Can anyone recommend a good article that covers this?
I have an "Edit" page that uses a FormView bound to an EntityDataSource. The page is called with the ID field of the record to edit in the query string: "EditEmployee.aspx?ID=10". The EDS the FormView is bound to is using: AutoGenerateWhereClause=true and a QueryStringParameter. Below the FormView I have a ListView that contains some child records of the FormView. The ListView is bound to a seperate EDS and also uses the (same) QueryStringParameter.
The problem I am having is when this ListView attempts to Insert or Edt a column I receive an error because I don't have the ID field (EmployeeID) of the parent bound anywhere in the ListView (and obviously, it is setup as a ForeignKey so it fails, like it should). Any advice on the best way to get this ID (EmployeeID) column bound in the ListView? There are many things I can do in code behind, but I would like to solve this in the markup if possible. I can move the ListView so that it is inside of the FormView if necessary.
What i need is i need to bind last 10 Order in Gridview/details view with paging, and the same order detail also fetch from database and shown in another gridview.. if user click any oderNo in first Gridview/DetailView then i need to show Respective order detail in anther gridview..
without postback coz we already fetch 10 order with orderdetails from the database..and if user click next 10 orderNo using paging then again we need to load 10 orderNo with respective orderdeatils from database like this going on....as well as let me know how to take print of particular oder and order detail....?
I want to set paging in a very simple way (unlike Gridview). Might be from code behind or inside Crystal Report viewer tag in .aspx page but in a very simple way as I am very new to crystal Report.
Regarding ASP.NET's GridView server control: Can I bind to a datasource in the code-behind, load the entire resultset, and then implement client-side paging without postbacks? If this isn't possible with GridView, I'm willing to implement a custom solution. EDIT: My GridView instance sits inside of a nyroModal (jQuery) pop-up div, which is why I need a non-postback solution.
article on binding to a list and I've got that working fine on one view. But what I'm stuck when doing it off a master record. Everything seems to work except that when I look in the database the detail records previous associated with the current master have their Foriegn key to master set to Null and a new set of detail records have been inserted. I've got a really simple form for this object
[Code]....
The form collection comes back with the expected prefixes:
[Code]....
And the Controller.UpdateModel(master) binds all the properties correctly. But when I call dbContext.SaveChanges it issues the follow sql from sql profiler (psuedo code)
[Code]....
I've got a work around that works but it's pretty hackish and I'm currently not matching up the keys so it's dependent on everything coming back in the right order. Plus I've got to include all the fields that I want updated.
[Code]....
I thought that entity framework's code first was the culprite but I've unit test that and it works fine. I've got a feeling that UpdateModel is somehow removing and re-adding the children. Has anyone else got this to work? Of course, I could throw in the towel and parse the indexed field names myself, but I'm so close!
i am applying paging in list view. i used data pager control. but problem is on click of next page next data is not displaying only showing previous data. i have one dropdown i am bing list view on dropdownindex change event not in page load.
I've been experimenting with using EF (asp.net 3.5 sp1) with a master detail page. Using northwind as the database, I'm simply trying to have categories as master and products as detail. I have read everything I could find on the net about the where condition and it still fails with this error as soon as I click the select link in the master grid:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: A property with name 'CategoryID' does not exist in metadata for entity type 'WebAppEF01.Products'.
What strikes me is that the CategoryID column is not exposed by the EF model. That's been rolled up into the navigation element 'Categories' I suppose...but on the surface this seems to create the problem I've running in to. I've tried turning off the autogeneratewhere clause but didn't have success. The code for this page follows below.
I have read many online articles showing how to implement custom paging with stored procedure and objectdatasource control. So I know the benefits of custom paging on large result sets and I know how to implement it.
In my application, I have a stored procedure which is using ROW_NUMBER and taking parameters such as startIndex, pageSize etc. I also have method in my DAL who call this stored procedure and on my page I have GridView and ObjectDataSource control and they are calling DAL methods and everything is working perfectly fine.
Now I want to implement GridView paging without ObjectDataSource control by calling the DAL methods manually. I dont want to use ObjectDataSource control because I need manual access to the DataTable my DAL methods return which I think I dont have if I use ObjectDataSource control.
how to implement paging without ObjectDataSource control
I have an array object with another nested arrayobject within it. I am binding the outer arrayobject to a gridview and on row data bound event i am refernecing the nested array object and populating a dropdown list in atemplate column of a gridview row. Thgis works fine but when i implement paging and handle the PageChanging event then the data binding of the nested array does not complete properly. See code below. For each page in the gridview the dropdown list is repeatedly populated with the same data
I have the basic Master / Detail Views working great with the default ASP.NET MVC Route; however I would like to build some URLs like this: /Class/Details/5 -- General Detail view [Working] What I'm not sure about (and I'm not tied to this URL format, just something roughly equalivent.)
/Class/5/Details/Logs -- Detail View with Logs /Class/5/Details/Status -- Detail View with current Status
Another way to put this, is like this: /{controller}/{id}/{controllerSpecificMaster}/{action}/ What I'm trying to avoid, is cluttering up my ViewsClass directory with a bunch of Views, which are all basically derivatives of the Details view. I'm on ASP.NET MVC 1 and .NET 3.5 SP1.
