C# - How To Delete A GridView Row

I have this code until now: <asp:TemplateField ShowHeader="False" ItemStyle-Width="150px" HeaderStyle-BackColor="#003ca1" HeaderStyle-ForeColor="white"> <ItemTemplate> <asp:LinkButton ID="linkDelete" runat="server" CausesValidation="False" CommandName="Delete" OnClientClick='return confirm("Diesen Eintrag wirklich löschen?");' Text="Löschen" /> </ItemTemplate> </asp:TemplateField> At this moment, the GridView deletes the row physically.I want to catch this in CodeBehind, cancel the delete-operation and want only set a "IsDeleted"-Flag in the database.

I'm now looking to implement drag-and-drop sorting functionality, make it possible to rearrange the level 1 and two rows.

C# - How To Insert A Copy Of A Row (with A New Identity) Using LINQ To SQL
stackoverflow.com
I have a number of tables that together make up a "Test" that somebody can take. There are multiple types (scripts) of Test a person can take. I'm working on an Edit function that will allow somebody to edit the Test Questions. I want these edited questions to show up on all new Tests of that type, but still show the old questions when viewing past test scores. To do this each "Test" has a TestId auto-increment identity (along with its name). When a test is edited I want to make a copy of the test with a new TestId and present the questions for editing. So what is the best way to make the copy and insert it into my table using LINQ to SQL? This: DataContext db = new DataContext(ConnectionString); //Copy old test into identical new test but with a different script ID var oldScript = db.TestScripts.Single(ds => ds.TestScriptId == oldScriptID); var newScript = oldScript; db.TestScripts.InsertOnSubmit(newScript); db.SubmitChanges(); of course tells me that I Cannot add an entity that already exists. Is the only way to do this to go through every column in the TestScript and copy it manually, then insert it, and the database will give it a new Id?

C# - Turning HTML Div Code Into A Control?

I have bunch of HTML code I am using to make rounded edge boxes on my controls.

C# - .Net XML Serialization Based On A XSD?
stackoverflow.com
I've been serialising and deserialising .net objects using the XmlSerializer class without problem, however we now need somebody else to look at that data to perform some analysis on it.In order to help with that we've produced an XSD based on our class like so: xsd.exe /t:DataClass Assembly.exe The start of the XSD looks like this: <?xml version="1.0" encoding="utf-8"?> <xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="DataClass" nillable="true" type="DataClass" />[code]..... Bizarly, the XML produced does not adhere to the XSD generated from the same class.My question then is, is there a way of telling the XmlSerializer to serialize the object based on a given XSD? As an aside, I've looked at other ways of fixing this: I've tried re-generating the classes from the generated XSD - this seemed to have the same problem.

C# - Serialization Across Projects With Inheritance?
stackoverflow.com
I have a base class ("MyBaseClass") in a project called "BaseFramework" which is included in several solutions within the company. There are several derived class's in various projects throughout the company that inherit from "MyBaseClass". If I then create a List and add derived class's to it, it will not serialize. I realise that if I were attempting to serialize this list, and the base class and derived class were in the same project, I could simply apply the "XmlInclude" attribute to the base class and include all of the derived class's. This is however not possible across projects, because that would require a circular dependency.

C# - XML Serialization Assembly For Non-web Projects

C# - How To Serialize Only Some Properties In .Net
stackoverflow.com
This is for a web project so i have several classes that inherit from Web.UI. I only want to serialize very particular properties (basically, only local properties) I'm aware of the XMLIgnore property that can be placed on a property to ignore items, but this won't work in my context since that would require modifying a bunch of stuff that i really don't want to modify (and probably can't). So how do i tell the xml serializer to ignore everything except for X and Y or tell it to seralize just X and Y? i could just create my own xml in a string builder or something and if that's the only way, so be it. however i'm looking for a method that will employ the built in XML stuff.

So now I want to use it in view-code but when I put it in angle brackets (<%: or <%=) and put it in head element I got no access to this value. On the other hand when I put it in BODY element everything is ok. My failing example (simplified): <head runat="server"> <script language="javascript"> function beamMeUp() { alert(<%=mystring;%>); } </script> </head> <body> <input type="button" onclick="javascript:beamMeUp" value="Warp6" /> </body> why I can't use it (the <%=mystring;%>) in HEAD but i can use it in BODY ?

Integrate HTML / Design With C# Code In MVC?
stackoverflow.com
We're working on a new ASP.Net site. The last major site we did was in classic ASP--the procedure we used there was to have the HTML completed first, then "bring it to life" with the ASP code. In the ASP.Net world, how does this work? I.e. how do the designers do their work if much of the mark-up is actually being generated by the server controls? We are also looking at ASP.Net MVC as a potential lightweight alternative. Would be very interested to know what was worked best for people in both scenarios in terms of working with the designers and integrating their work with the code. UPDATE: I refined what I was asking here, not exactly the same question but similar enough so this one could probably be merged with it.

MVC ::difference Between C# And VB.NET?
forums.asp.net
I am in the process of learning MVC, and thought I would parallel the work in both C# and VB.NET.  I ran into a snag when right-clicking in an action method inside of a controller to add a view - in C# if I choose to strongly type the view it includes all the objects in the models folder in the drop-down list for selection; however, in VB.NET none of the models are available in the list.  Is there some step I need to take in order to make the models objects available in the drop down for selection?

C# - Using Outputcache Together With Urlrewriting
stackoverflow.com
I've got a problem using outputcache together with urlrewriting. We've got an application that rewrites url (IE [URL]). Based on the URL (/about/) we figure out which content to show. Now we're trying to add outputcache to that page: < %@ outputcache duration="600" location="Server" varybyparam="Custom" varybycustom="RawURL" %> And in the Global.asax we override GetVaryByCustomString like below: public override string GetVaryByCustomString(HttpContext context, string custom) { if (custom == "RawUrl") { return context.Request.RawUrl; } else { return string.Empty; } } However, when we publish the page i'd like to invalidate the cache so that the editors see the change directly. But no matter what I try, I cannot seem to invalidate the cache. If I'd like to invalidate "/about/" I would like to do this: HttpResponse.RemoveOutputCacheItem("/about/"); That doesn't work unfortunately. The only thing that seems to work is: HttpResponse.RemoveOutputCacheItem("/page.aspx"); This clears the cache for all my pages, not just "/about/". Is there any way to invalidate the cache based on the url? Or should we provide a cache key or something per page to be able to invalidate the cache programmatically?

Show / Hide Sections In A Datagrid Row?
stackoverflow.com
I have a datagrid where each row has information on Employees in a company. I would like to allow each row the ability to show/hide extra information. My first idea was use the CollapsiblePanelExtender from the AJAX toolkit and have each row like this: <ajaxtoolkit:collapsiblepanelextender TargetControlID="panel2"> ExpandControlID="LinkButton1" [Code].... This works very well but it can be computationally expensive. The extra information panel has a lot of textboxes/labels, all of which gets its values from the database. Everytime the page loads all the data is got from the database at the start, some of it is hidden. Is there a better way to achieve my goal? Or is there a way to only load an employees extra details when the Show/Hide button is click?

Web Forms :: Web Page That Allows Multiple Database Row Updates
forums.asp.net
We currently have a page with a listview control that has textboxes and an update button for each row. Users are able to update the database one row at a time.This is problematic in countries where the internet connections are very slow because a round trip is needed for each row update and this can become impossible to use.We need to create a page which allows multiple row updates so that each round trip is more productive.  There woudl be just one update button on each page and users could enter values into each row.  Clicking the update button would update each changed row of the database.We currently use linq 2 sql.  I would imagine that we could still use this in the above scenario??? Or is there a better data connection methode to use in this scenario.

C# - ELMAH - Only Sending Specific Exception Type Via Mail
stackoverflow.com
I have ELMAH set up for a webapp, logging exceptions to a SQL server. I wish to have ELMAH send me an email too, but only when a specific exception is thrown (ie. MySpecialException). ELMAH must still log all exceptions to SQL server. I know you can do it programmatically in global.asax, but I'd prefer to use web.config. So, how do I restrict ELMAH error mails to filter out everything but a specific exception type, using web.config? UPDATE The filter ended up looking like this: <test> <and> <not> <is-type binding="Exception" type="MyApp.MySpecialException" /> </not> <regex binding="FilterSourceType.Name" pattern="mail" caseSensitive="false"/> </and> </test>
