View 3 RepliesMembership/Role/Profile providers API appeared in early days of asp.net Nearly everytime I can't live with standard API & have to add some extra functionality (for sorting, retrieving e.t.c.). I also have to use different database structure often (with foreign key to some tables for example) or think about performance improvements.
These considerations forced teams I took part in to build own providers but I can't stand to implement providers API (because we don't use 70% of standard functionality at least). Moreover, providers that were built for exact projects were rarely reused.
I wonder if someone found swiss-knife early-days-API providers implementation that is usefull for any kind of project without refactoring. Or do you use your own implementations of early-days-API's Or may be you abandon standard architecture and use lightweight implementations?
Following is my case in detail.I have a class against which I will configure an objectDatasource(I have a datatable in the class which the data will be initially loaded from the database.)A gridview which has provisions to add/update/delete records will be bound to the objectdatasource
My methods i.e. insert/update/delete will be manipulating the datatable and NOT the database directly(I DONT WANT TO CONNECT TO THE DATABASE IN THESE STEPS. THE REASON IS THAT THE INSERTS/UPDATES/DELETES WILL BE PERSISTED ONLY WHEN THE USER CLICKS A SAVE BUTTON(MAY BE PLACED OUTSIDE THE GRID) . My class to which the objectDatasource points to will have anadditional AcceptChanges method which will be called on clicking the save button. This method is the one which connects to the database and where the adapter.update will be called.The query here is that how do I call the AcceptChanges method of my class instance which is bound to the grid? Also I would like to get some websites where I can see the real world implementations of gridview(with insert/update/delete options) so that I can improve my implementation.
I have a following generic list method that contains some data for a gridview. I need to supply edit and delete functionality for it.
List<students> List(string id)
{
List<students> st = new List<students>();

URL.... Still there will be need of url in ajax method if i put javascript in site.master.cs . As what i have understood from that mysite.master.cs will be like this :

UserNameMasterLabel.Text = Session["UserName"].ToString().Trim() + " (ADMIN)";

And site.master will be like this :
And I have to put next method in DailyLog.aspx page ? like this

HttpContext.Current.Session["Name"] = "BSD";
Configuration config = WebConfigurationManager.OpenWebConfiguration("~/Web.Config");
SessionStateSection section = (SessionStateSection)config.GetSection("system.web/sessionState");
int timeout = (int)section.Timeout.TotalMinutes * 1000 * 60;
return timeout;
}
But I have several pages in my website , by doing the above story will it work for Builder.aspx ? or any other page rather than dailylog.aspx ?

we are getting a stack overflow in production ~ 2-4 times / dayWe cannot reproduce this is in dev environment, nad given this is a web app with probably ~100 concurrent users at any one time, I'm struggling to work out how best to track this down.Is there anyway to get any more info from event viewer - happy to install some form of listener tool - even if i can just get teh thread identity (set to the current user) that'll help - although the dll + class / function woudl be great!

View 7 RepliesI'm using ASP.NET for a search app web site.My search retrieves exactly one result per fetch. Once the search is complete and the user selects "Update", a new result is fetched and the old result is written to the ViewState as a generic List. The new result replaces the old one.I am trying to get the page to update (via partial post-back), so that the old result drops down the screen and the new result sits on top of it. Much like the concept of a stack.
