Forms Data Controls :: Real World Implementations Of Gridview?
Mar 15, 2010
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.

develop a user admin application.My schema looks like the following:See full size As you can see I've got my own version of the user table and profile tables to store my data with a one-to-one mapping with aspnet membership tables.I'm interested in using ASP.NET dynamics to speed up the proccess of creating an admin system.
I would like to create a customised listing with a search and a data grid listing with just basic details such as name and state information, date registered and then when you click to edit your presented with the domain representation of the data and not the exact undelying data.Has anyone any experiece in doing this or building a real work application with Dynamic data?

I have a Table (in SQL Server) that is being updated roughly every minute or so with new records being inserted from various sources. The number of records inserted in this duration varies from a few records up to dozens of new records. I am using an update panel to rebind my data every minute to keep the GridView current. Now that I have the data refreshing I am looking for a better solution than reloading the data every minute. how to best keep my GridView up to date? Here is what I would like to accomplish:
1. Load the GridView and refresh the contents every minute. (60 second intervals)
2. When the GridView is refreshed every minute I would like to append only the new records to the existing grid, rather than bringing back the entire result set with each round trip to the database.
3. I would like a visual cue to identify the rows that have been inserted into the GridView. If new rows were to flash/flicker with a background color (yellow) that would be ideal.
Am I even using the correct control for displaying real time data, or are their other options? I essentially am looking to find the preferred method of displaying data that is being updated in real time in a web application. I'm hoping there is a solution involving AJAX but I haven't been able to find much on The Google. I am open to changing anything and everything about my approach -- this is largely a learning exercise. For testing purposes I am currently using LinqDataSource in conjunction with a GridView in an UpdatePanel being refreshed by a Timer control every 60 seconds. Informational: I have also started playing with the [URL] in place of the Timer control. However, for the purposes of this example I would be content to achieve the desired behavior using native controls as I have described them above.

How would you implement a user message stack in ASP.Net MVC? (you set messages for the user in any place inside your app. and they are shown as hints of your app to the user anywhere inside the app)

Membership/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?

I need to build a system which needs to show data on almost near real time basis from a MSMQ data source and this sould be showin in image with a circle as to where the incident occurs.
This is the description given.
The position of the Incident relative to the 123 mark is requested to be represented on a circular concentration diagram .
The algorithm will have to export the location of each incident relative to the 123 mark in polar coordinates (r,θ) and translate this position to the 'master image' coordinate system that will display Incident location.
I have two questions.
1. How can i show the data in an Image and also please point me to any material which might help me with the same.
2. How do i show almost real time data from a MSMQ data source and also how do i architect the same for performance.

What my clients are used to: VB6 app running locally - can produce reports and labels directly to printers. How do I take that same user now in a web page and have them get that same report or label sent to a printer? Do I need to make a little VB6 or VB.Net app that sits locally to receive the DATASET and perform the print formatting? I should mention that all the print formatting information is in a table in the DB anyway. Or do I need to make PDF's or some other kind of document format on the server and send that to the user from the webpage.

I've been a VB programmer for years, and friend asked me to write a program that does data storage and is executable from PC & MAC browsers. It seems like I need ASP.NET for this, so I tried to write a server-side 'hello world' ASP.NET program. I did this using VWD 2010 Express, and after successfully 'building' the website, it works great if I view it on the development machine. But when I copy it to my web server (running on a Windows XP Tablet machine) and try to view default.aspx, instead of getting a nicely-formatted page, my browser (IE8) is displaying the HTML source code. I tried hosting the site on both Apache and IIS , and I'm getting the same results.
1. What am I doing wrong?
2. Is ASP.NET the best platform for building a database-based application that can be viewed from both PC's and Macs? If so, should this work from iPads / Safari as well?
