What is the best way to disallow editing of existing entries in ASP.NET Dynamic Data while it should still be possible to add new entries? If possible, I would prefer a solution without custom templates.
View 1 RepliesI have a requirement like, There is a grid that has multiple rows. On clicking the "add to list" button, the columns from this grid is added to list of tables where source for one table in this list is read from grid view. note that, the grid view and tables will be having just two columns but the rows added to each table might vary.
I trying to implement this using GridView inside a gridview option but looking for some lighter way to implement this.
Example: we have different articles in a database like cars, jewelery, boats. The data related to these articles is different in the tables. I have to show that data in a textboxes and let the user change those data and update. I can do the update and reading the data from database. But the problems is for each item the no.of columns and rows will differ.
My task is I need to get the data according to the use selection in the table with textboxes. I dont know which container (gridview, formview or etc) will suites for my requirement. send me any sample code or any tutorial related to this.
Note: showing the data in a table should be a constraint. Because I should show data row wise (each row contains 3 textboxes and 3 labels (DB table column names))
I combined MVC and DD by creating a new DD project and adding the MVC stuff (references, routing, usings, etc). The list of tables on default.aspx (from DD) will show all tables, including the ones with [ScaffoldTable(false)]. The URL's of the tables with Scaffold==true have the expected form (DD/TableName/List.aspx). However, the URL's of the tables that should not be shown are in the form /Home/List?Table=TableName. If you leave out the MVC routing (Routes.MapRoute) then the tables with Scaffold(false) are not shown. Or you can leave out only the Parameter defaults.
My guess is that Dynamic Data determines if a table is visible by checking to see if a route can be made to for the List page. The DynamicDataRoute will not match because that will not generate a route if Scaffold==false. BUT THEN the MVC Route WILL match because of the Parameter defaults at the end. Am I correct and is this a bug or am I completely missing something here? EDIT: I fixed it by adding filtering the VisibleTables on Scaffold like this, but that's a workaround...
System.Collections.IList visibleTables =
MvcApplication.DefaultModel.VisibleTables.Where(o=>o.Scaffold==true).ToList();
My RegisterRoutes in global.asax.cs:
public static void RegisterRoutes(RouteCollection routes)
{
DefaultModel.RegisterContext(typeof(studiebase2Entities), new ContextConfiguration() { ScaffoldAllTables = false });
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.Add(new DynamicDataRoute("DD/{table}/{action}.aspx")
{
Constraints = new RouteValueDictionary(new { action = "List|Details|Edit|Insert" }),
Model = DefaultModel
});
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}

I'm looking for a regex that will allow Alpha Numeric and most all special characters except white space. It should be usable in c#. It would be nice if .net supported posix style but I can't seem to get it to work.
View 1 RepliesI have a table created on the front end of my code called "tblSearchlist". In my code behind I have the following.

All this code works fine. What I want to do now is insert another dynamic table within cell1. Any ideas how to do this. This process can be done on the front end like so but I need it in code behind.

Is there a way to disallow the asp:Literal from outputing HTML ?
If I input the text <b>Hello world</b> I want to show it just like that, and not in bold.
If possible I don't want to extend it, because I would have to change the whole project.
Here is my dilema, on my site i have a WordPress Audio player (http://wpaudioplayer.com/standalone) that plays my mp3's.
It loads the Mp3's in by javascript...example below:
AudioPlayer.embed("audioplayer_7", { soundFile: "/Files/Music/[name of file].mp3" });
This file name is clearly visible in the browser source. Not a problem, however this means that any user can legitimately browse to the file directly and download it.
Now i still need the mp3 player (which is flash) to have access to the file but if a user was to try accessing the file directly, they would not be allowed access to it.
I am not sure how to go about this, i am circling the idea of a httphandler but not sure if this is sufficiant to stop the direct access to the file.
How to disallow use of double quotes " in a textbox
View 5 RepliesI just wanna ask if there's a way in C#/ASP.NET to create 'dynamic' tables/fields similar to phpMyAdmin:
View 4 RepliesHow do I achieve this:-When user types character like 'abcd' and then '>'(an invalid character for my application), I want to set the text back to 'abcd'. Better if we can cancel the input itself as we do in winforms application. This should happen when user is typing and not on a click of button.I want this to be applied on all text boxes in my web page. This will be easy if the solution is jQuery based. May be something which will start like this.$("input[type='text']")SOLUTIONI used both of the answer provided by @jAndy and @Iacopo (Sorry, couldn't mark as answer to both) as below.
$(document).ready(function() {
//makes sure that user cannot enter < or > sign in text boxes.
$("input:text").keyup(purgeInvalidChars)

I am using bulk insert concept to export the data from dat file to tables(Two tables). I am using the temporary table for to do the calculation and insertion to two tables. My problem is whenever I selecting the temp table data after the execution of bulk insertion , the order is changing .I need to get the order as it is in file order(csv,dat,txt).
View 5 RepliesI have loaded up a gridview object with data. I have turned on Edit on the grid. It lets me edit the data, but I also want to put some code to check for correct data in each field. I tried to assign a requiredfieldvalitor, comparevaliditor but they don't work. Is there an event I can capture to fire up some code before the grid sves my data?

I have a loop which creates for each item ID a Dynamic created checkboxlist control
how do I create a dynamic validation control on a dynamic checkboxlist?
I am learning ASP.NET MVC with "Professional ASP.NET MVC 2" but it seems that I am still far away from basic knowledge. My problem is that I have a page where I must subscribe users for a tournament. My url is something like "Tournaments/Subscriptions/1" and it will show all users with a editable checkbox indicating if the user is currently subscribed. I have created a new ViewModel object called SubscriptionViewModel which is something like this:
[Code]....
But the method can't be called, since it gives the following error: No parameterless constructor defined for this object. Obviously I am making a big error here, but I don't know where to start.
I just finished making a change to an ASP.NET Ajax screen from a few years back. It was harder than expected to build and maintain. On this change, I estimated 12 hours and spent 4 days. Granted I also did extensive refactoring to simplify the code. This is actually some pretty fun code, but I wonder if there was a better route for the original implementation than the one I took. To start, here's a screenshot:
The Problem So obviously this is an editable tree of data. The data behaves very differently at each level -- very different sorting/collision rules and so on. My solution is actually performant and provides an adequate user experience, but it's nearly 2,000 lines of code spanning 11 classes, which is more than I envisioned going in. I'm curious if you've solved similiar problems and if you were able to find a simpler solution. It looks pretty straightforward at a glance, maybe that means I did something right. But there is some real complexity here -- obviously you can add and remove items at three different levels, and everything sorts similiar to a netflix queue, but with quirks. It also has to detect collisions on the various entities (in the image, if you changed day 5 to day 1, it would have to figure out which one is actually day one and move the other one).
The biggest problem was keeping track of the state, since users don't want to commit changes to the database as they work. I thought it might be possible to use the actual controls (nested repeaters in this case) to represent this interim state, but that ended up being a dead end due to complexities related to the underlying data. The Solution To solve this, I created a full blown XML representation of all the data, which was actually great in some ways since I was able to use LINQ to do a lot of heavy lifting around sorting and querying. Still, there is a lot of code in here related to syncing up the xml to the html and so on, and I had to make a pretty hefty abstraction on top of the xml to make it easy for me to work with it in code. In case you're interested, I am currently persisting the XML to session state so that it will survive across callbacks, but eventually that should go into the database.
One colleague told me it would be better to use Flex or maybe Silveright for something like this, and I think that might be true since those are both much more stateful, although Silverlight was not ready for prime time back when this started, and I don't know Flex. Maybe using a temp table instead of xml would have been superior in some way. I'm looking to learn and improve -- what have your experiences been with this type of problem?

I have an C# ASP application I am writing that needs to have the capability to import a generated excel or a comma delineated sheet each day. A clerk will have this job each morning so it doesn't need to be automated. My problem in trying to understand the solution to this is that the 1 sheet contains loan information, including customer information all in the same sheet. I would like to send certain columns to update information in the loan table and send other information to update the customer table. I need it to create relationships when new loans appear in the spreadsheet.
View 1 Repliesregarding editing and updating the data in the gridview?
View 4 RepliesI have made an ASP.NET page with a ListView which binds to a Linq datasource which have inserting, updating and deleting enabled. All very trivial and well designed by MS. It all works very well so far.
Now I add a DropDown control to the page and binds the Linq datasource Where clause to the dropdown using the following code:
[Code]....
Now I can filter the listview based on the DropDown control. It works very well and I can still insert and delete rows in the ListView.
PROBLEM:
However when the DropDown control is used to filter the ListView rows I can no longer use the Editing functionality of the ListView. The row never goes into editing mode when the Edit button is clicked.
When the DropDown is not used for filtering - is in default state - editing works as expected.
