I know there is a serial problem with the gridview in webform:
if the data is too much as 100 thousands rows and more, and we 'select * from tableName' and bind data to the girdview, when the girdview pagination to last page , it will crash out! Then we should use ' DataBase pagination ' way. so, we use Linq to sql,Linq to Entity etc. to fetch data from database, using ' DataBase pagination ' , the WebGrid won't crash and it will take a short pageload time.
Is there any good way of Linq to sql / Linq to Entity for DataBase pagination ?
I currently have a datagrid bound to a table with tens of thousands of records. I display the datagrid using the existing asp.net 2.0. I show ten records at a time.
My problem is whenever I try to access the next page, I gets all the records again from the database and then displays the ones that are required. This is slowing down the app. Is there feature within .net 2.0 which will help me optimize this issue? I cant use third party controls or ajax.
UPDATE I cant use SQL to get 10 records at a time as well. Without changing any existing business logic or data retrieval, I want to do this.
This seems like a basic question, but my searches haven't turned up an answer. Is there a way to use a DataTable as the source for the WebGrid helper? The constructor wants an IEnumerable<dynamic>, which a DataTable is most definitely not.
I am using Razor and MVC 3 WebGrid in ASP.NET MVC 3 Beta.
I have the following:
[Code]....
I am not able to have two ActionLinks on the same column. In this case I get the following error:
The best overloaded method match for 'System.Web.Helpers.WebGrid.Column(string, string, System.Func<dynamic,object>, string, bool)' has some invalid arguments
This is usefull not just for this but to create columns that contains more information then just a field.
I also tried Razor's <text> but no luck ... Maybe I used it wrong.
we are testing the Razor webgrid with Ajax. Works absolutely fine in IE8 when sorting in paging. However in IE7, any attempt to sort or page causes the grid to vanish from the page, leaving a blank space. The HTML that should be there, isn't!Has anyone come across this issue? How could we debug it? Page code below:
I've been practicing with WebMatrix and I've come across this problem. I'd like to use the format property of the WebGrid Column in vbhtml but I can't get it to work. I always get some kind of compilation error. Mostly the compiler says that an expression is needed. There must be a crucial difference between the way it's done in cshtml and the way it's done in vbhtml.
My webGrid is working perfectly fine. However, I would like the default sort order to be in the opposite direction. If it were SQL, I'd be adding a DESC somewhere. Here's my working line of code:
[Code]....
It correctly sorts on the UWDate column, but I would like it to sort the opposite sort order. Of course, once it is displayed, you can click on the title and it will resort at that time.
I have a Car class that I'm trying to display in an MVC 3 view using the WebGrid helper. Below are the Car and it's metadata class.
Car class:
[MetadataType(typeof(CarMetadata))] public partial class Car { // car implementation } Car metadata class: public class CarMetadata { [DisplayName("Car Name")] [StringLength(100, ErrorMessageResourceType = typeof(ValidationText), ErrorMessageResourceName="CarNameDescriptionLength")] [Required] public string CarName { get; set; } }
View contents:
@model List<Car> ... var grid = new WebGrid(Model, canPage: true, rowsPerPage: 10); grid.Pager(WebGridPagerModes.NextPrevious); @grid.GetHtml( htmlAttributes: new { id = "grid" }, columns: grid.Columns( grid.Column("CarName", ?????) ));
GOAL: I'd like to figure out how to use the DisplayName data annotation as the column header text in the WebGrid (?????). Does anyone know how this is accomplished?
I am using a Webgrid as part of an MVC 3 app. The weird thing is the first display of the page with the grid displays fine but when I click on a heading to sort, the grid is not displayed as part of the page when I am running under the web server provided by the VS 2010 installation. When I do a View Source of that page, all of the grid stuff (as table elements) is there to be displayed. It just does not show up in the browser. So, I wrote the html to a file and copied the javascript and css files to the same folder and then ran the file under IE and everything displays as it should.
Just in general, where can I find the code to take a look at and learn from them? Or at least look at the functions available to me as I do get the feeling that the insufficient documentation at the moment reveals all.
I've been programming php for ten years,. well really I'm just an all around web guy. I run a local company and times have been rather hard this past year. I hooked up with another local company who has more work then they can deal with,. and took an asp.net job. At the time I had three weeks,. so of course I'm thinking,. hell I can learn to program alien type in three weeks. At least enough to get this job done. Now,. I know what your saying,. and I agree,. the last thing I want to do is give a half ass performance on this and give my company or the company I'm working with a bad rep.
So everything started pretty well,. I'm sure you all have been there,. beating your head against the wall trying to figure out stuff that with your native language would take you minutes. Then of course,. life happened. Dad had a heart attack(after a few miracles he is doing fine,. guess he is going for the record with 5 attacks now) and lord knows I haven't had more then three hours sleep in the past two weeks. Now I'm in the position of facing the clock. I have to make several things,. but the one due very soon is a simple article system. I have created the email to someone stuff,. I have connect to the database and done the add, edit and delete stuff on the backend. I have done the master detail type pages,. and so on. What I'm looking at a simple pagination script.
Ok so I've been on google and the like and I know the better way to do it tbh. I know about the datagrids and all the like(or at least I have heard of them). However tbh I don't have time to learn this for this project. I want to as I would like to take the next step to be fluent in vb/asp.net as well. However as I have stated I don't have the luxury of time. So tbh what I am looking for is a simple script,. maybe what you guys would call oldschool style(maybe you wouldn't lol). Something like what I would use for php,. something with url vars that determine what page you are on and simple limits on the query itself. I am using mssql & asp.net/vb. What version I can find out very quickly I think. 2005 for mssql I think and I'm not real sure on the vb version,. however if needed with a bit of research I bet I can find that out as well.

I was trying to play with Pagination Support in Repeater, PagedDataSource rescued me. I made the following method and would like to share with all of you whether there is any pitfall or is there any chance for more improvement.
i am new to this mvc framework in asp.net. My problem is I have implemented pagination in my application and its working fine asp.net development server when i click to the page link on addressbar it shows me http://localhost:1139/eigencrm/AdminUsers?page=2 and display the lists on second page.In the AdminUsers Controller i have defined the method called Index and page as follows
public ActionResult Index(int? page) { List<userview> userview = _entities.userview.ToList(); PagedList<userview> data = new PagedList<userview>(userview, page ?? 1, 2); return View(data);
[code]...
But it doesnt work on IIS server it gives me an error page not found Is there problem of routing in global.asax or the problem of IIS server version.please help me i am have to deploy pagination on IIS server which is right now not working but on local server it is working.
It doesn't ever seem to hit my AsyncHandler, not sure if my selectors are wrong since I'm using a Masterpage in ASP.net, but it seems to be picking up the elements.
