Whenever I write lines like this:
<%: Html.LabelFor(model => model.AccountName) %>
And save the file, some lines (some, not all of them, haven't figured out the logic behind this yet) will be converted to this:
<%: Html.LabelFor(model => model.AccountName)%>
Whenever I enter data in a text box, such as two words with many spaces in between, on postback .Net appears to automatically replace the many spaces with one space. I want the data to be exactly as it is entered in the text box.
textbox: word1 word2
postback result: word1 word2
desired result: word1 word2
I have a long string containing the ,<p> </p> and <br>. I want to clean my string from all these tags and spaces. How it can be done with String.Replace() method. I am doing separately right now, it is working but is there a way to do it at once, without replace() method.
String.Replace(" ","").Replace("<p>","").Replace("<br>","")
It is giving me clean code but I am looking for a general solution, means if I am having more tags (10 to 20) to filter then how to do it efficiently.
I want to redirect to login page,when session is timedout. Here is the link i am following [URL] ...
For example: If i am in the page called http://localhost/RealWebApp/Dashboard/RealProfile.aspx
when session is timed out, this page is showing like http://localhost/RealWebApp/Dashboard/logout.aspx
But i wanted to be like : http://localhost/RealWebApp/logout.aspx
If I use like this in master page:
meta.Content = Convert.ToString(Session.Timeout * 60) + ";url=../LogOut.aspx";
then it is redirecting to http://localhost/Logout.aspx
But i wanted to be like : http://localhost/RealWebApp/logout.aspx
How to accomplish this:
protected void Page_Load(object sender, EventArgs e) {
HtmlMeta meta = new HtmlMeta();
meta.HttpEquiv = "Refresh";
meta.Content = Convert.ToString(Session.Timeout * 60) + ";url=LogOut.aspx";
this.Page.Header.Controls.Add(meta);
}
i have created a aspx page with the script manager, update panels and so on. Now, when i use some jquery functions which are included inside the head tags, when the page is run, i find the script tags generated inside the body instead of the head tag. i'm using visual studio 2005 only.
View 2 RepliesI am building a forum and I want to use forum-style tags to let the users format their posts in a limited fashion.Currently I am using Regex to do this.As per this question:How to use C# regular expressions to emulate forum tags. The problem with this,is that the regex does not distinguish between nested tags.Here is a sample of how I implemented this method:
public static string MyExtensionMethod(this string text){return TransformTags(text);}
private static string TransformTags(string input)
{string regex = @"[([^=]+)[=x22']*(S*?)['x22]*](.+?)[/(1)]";
MatchCollection matches = new Regex(regex).Matches(input);
for (int i = 0; i < matches.Count; i++)
var tag = matches[i].Groups[1].Value;
var optionalValue = matches[i].Groups[2].Value;
var content = matches[i].Groups[3].Value;
Now,if I submit something like [quote] This user posted [quote] blah [/quote] [/quote] it does not properly detect the nested quote.Instead it takes the first opening quote tag and puts it with the first closing quote tag.Do you guys recommend any solutions?Can the regex be modified to grab nested tags?Maybe I shouldn't use regex for this?
Is it possible in my code behind,to remove one specific item from a dropdown box that is bound from a sqldatasource? I've tried, but can't figure this out.
View 3 RepliesThe following is a note from Professional ASP.NET MVC 2 by Scott Hanselman ++
You might ask — why did we go through the effort of creating a <form> within our Delete Confi rmation screen? Why not just use a standard hyperlink to link to an action method that does the actual delete operation? The reason is because we want to be careful to guard against Web-crawlers and search engines discovering our URLs and inadvertently causing data to be deleted when they follow the links. HTTP-GET-based URLs are considered safe for them to access/crawl, and they are supposed to not follow HTTP-POST ones. A good rule is to make sure that you always put destructive or data-modifying operations behind HTTP-POST requests.
If web-crawlers and search engine have no access to the page containing deletion button, is it safe to use a standard hyperlink to link to an action method doing the actual delete operation?
I'm working with a ListView and I have a problem: When I click the delete button, I need to know before deletion takes, the index of the item, because I have to do something before this event happen

I have an sql table in which i have two columns enq_no and enq_serial.
for a particular enq_no, enq_serial should get incremented by one starting from 1.
What is the best approach to achieve this?
another issue is that after deletion enq_serial should get decremented by one.
How can i get this?
Is after delete trigger could be a good option?
If so? how can i get this with after delete trigger?
Is there a way to apply your own CSS tags to <li> tags when using ASP .NET 4.0 menu control? For example, say I have an external style sheet that has tags "class1", "class2", "class3", and etc. I want to apply "class1" to the first menu item. Then if menu item is selected, I want to apply "class2" and if it's not selected, "class3". I played with various 'Static' styles, but just can't get it work. I finally gave up and created my own menu control that extends ASP .NET menu control and provides my own custom rendering. This works, but I'm wondering if there is a way to get it work with built-in menu control.

I'm trying to add the code, programmatically, to ask the user if they want to delete a record that is being displayed in a DetailsView control. It is called Tutorial 22: Adding Client-Side Confirmation when Deleting by Scott Mitchell. how it could be done in a DetailsView. Here's some of the ASPX code:

And here's what I've got for my DetailsView1_DataBound() event code:

I have a system in which users can enter records into a database via ajax. Each user may hold many values in the database, with different pageId and itemId values. Each user is identified by a GUID set to a cookie. The system needs to prevent the user from entering two pieces of data with the same pageId and itemId, so I've created a script to do two database updates:
Firstly, all records are deleted from the database where the memberGUID, pageId and itemId fields match (i.e. they've already added this item).
Secondly, the record is then recreated.
It all works brilliantly, except when the GUID value is passed into the delete statement, then I just get a caught exception.
So this works:
[Code]....
But this doesn't:
[Code]....
The weird thing is that because the GUID value is being saved in the second database call, it is definitely there and is definitely the right data type etc. Even if I hard-code it into the delete procedure it still causes the whole thing to fail.
why it's failing when I add the GUID parameter in the deletion process?
There is a Gridview(say with 5 rows) in my web page with Delete button inside it.
I want that when I delete any row( say I deleted 5, 2, 3, 1) and then when I try to delete the last remaining row i.e., 4 then it should not get deleted.I want that remaining any last row(can be any) in Grid should not get delete.How to achieve that?

View 1 RepliesI have an .NET 4.0 / C# web application that contains pages with GridView controls on them. There is an Entity Data Model and EntityDataSource objects that allow for CRUD operations against the database. My questions are the following.
How can I setup the delete command in the GridView to delete recursively, given my setup? In otherwords, how do I cause it to delete the record selected as well as any records related to it, and any records related to those, and so on? Also, how do I incorporate verification of deletion before deleting? What I would ultimately like is a 3-button window to pop up. "Delete", "Delete Recursively" and "Cancel" would appear. I'm also open to other suggestions for a better way to do this.
I have a bound datagridview with the associated tableadapter, dataset and bindingsource. A different component in our application can add or delete rows displayed by the datagridview. When this happens, the underlying database edits are correct. The problem is that the datagridview seems to lose track of the data.
Currently, when we receive the event that our data has changed we do the following.
this.DataSet.Offers.Clear();
this.TableAdapter.Fill(this.DataSet.Offers);
this.BindingSource.ResetBindings(false);
this.DataGridView.Refresh();
If our example had something like 5 items displayed in the grid and a row was deleted, the grid refreshes with 3 items shown. If we manually refresh our grid through a button calling the exact same code, it displays the correct results. Is this an asynchronous call? Should we be refreshing the grid in a different area?
How can I remove all html tags and script tags? consider also short tags like unclosed tags
