.net - Switching To FormViewMode.Edit Is Very Slow?
Jun 16, 2010
When i switch an ASP.Net Formview from readonly mode to edit mode it takes more than 6 seconds(from edit to readonly takes a split second). I have no idea whats the reason for it. The EditItemTemplate contains a lot of controls(table,textboxes,dropdownlists) but in fact not more than the ItemTemplate has. Yet i have even commented out the complete FormView.DataBound where the controls are data bounded but without significant change. My ASP.Net Web Apllication is using Ajax and the Formview is completely nested in an UpdatePanel.
Any suggestions or assumptions for this behaviour?
EDIT: I have removed all Ajax Controls from the EditItemtemplate and now it performs as fast as the Itemtemplate. What can be the reason for it? Following controls removed:
Student Name: John Exam Grade MidTerm1 A MidTerm2 B
For this, I defined a class 'Student' that has the properties StudentName[String] and Exams [a list of ExamGrade objects which has the Exam and Grade properties]. And I am using nested listviews to display the data. Here is the markup for the ListViews:
[Code]....
And the StudentInfo class looks like this:
[Code]....
And Exam class has just two properties.
Now the issue is that I have to press the Edit button [link button] twicw to get the EditItemTemplate. Even then I would get the blank textboxes. So what should I do to make the EditItemTemplate appear on the first click and the TextBoxes to appear with the existing data?
I have been using C plus plus throughout my semester but now i want to switch to .Net but before i start i was wondering how different it is from C? and how much work i will have to do to master this?
I am programmer analyst working mainly in Asp.net for more than 3 yrs. I always wondered why employers are ready to pay more dollars for the same skill a person have in dotnet. I also see more BPM technologies are based on Java. Like Pega, Tibco etc. I have learned java in my college 4-5 years back.
I have an application I would like to force SSL on the login page and on the page that the CC is entered on. I would prefer to keep the rest of the application free of SSL.
I have the code working to force SSL on certain pages, and remove SSL on others. The problem I have is that if I log in with SSL enabled the user is only authenticated on the pages that are SSL. The reverse holds true as well, if the user logs in without SSL they are only authenticated on pages without SSL.
What can I do to have this persist between the two. Is this using cookies or the session?
We're currently using Wilson ORMapper with our asp.net 2.0 website against an Oracle db and we're having some issues that is making us look into an alternative ormapper. I know there is nhibernate but are there any other we should look into for our environment (.net and oracle db) or has nhibernate become the industry leader and therefore we don't need to look any further.
I am working on a website web site where each user has a culture setting to allow control of resources displayed. The main page has two views, one the log on screen, the second the main menu.
When first loaded the page displays with the culture settings of the previous user (if any). If I then log on as a user with a different culture setting the view changes to the main menu without changing the culture. Go to another page and the user's correct culture settings are picked up, go back to the main menu, uses the correct culture etc.
This is logical but is there a way (without redesigning the site to have a separate log in page and main menu) to reset the culture to the new user's when switching view?
I have a very simple bilingual site with a link at the bottom that will allow users to switch between the two languages (english/french). the the web.config I have the following line:
<globalization culture="auto" uiCulture="auto" />
This allows for whatever the users browser culture is to be the default lanauge but I'd still like the ablility for them to click a bottom button to toggle. whats the best what to go about doing this?
I am running into a unique problem (not easily googleable). This is what I am trying to do:Will be using subdomains: x.abc.com, y.abc.com, z.abc.com, etc.There will be single website hosted at abc.comBased on the subdomain passed (x,y,z,etc.), I need to switch databases and web.configs (appsettings, authentication, authorization info)For ex: If a user goes to x.abc.com, the site will select appropriate db & config settings and forward user to abc.com with db & settings cached/saved for the user session.Is it possible to have one hosted site and multiple subdomains that select appropriate config settings? Reason I need to do this is because credit card processor needs static url for requests and responses.
I'm trying to use ASPxPageControl ase a template for my wizard. I put buttons on each page and connected it to javascript which simply changes active page, for example:
Pc1Client.SetActiveTab(Pc1Client.GetTab(1));
It works correct when tabs are visible but when I set ASPxPageControl1.ShowTabs = "false" then when trying to change tab by clicking my button an error is raised (sth that formant with that name already exists or sth like that, i ve got error message in polish)
I have a hybrid ASP.Net web forms/MVC app. On one of the MVC "pages"/views, I have it render a bunch of dates using the ToShortDateString() and ToLongDateString(). These work correctly most of the time, but the first time I load the view after compiling the app, they are formatted incorrectly.
I traced this down and checked the current thread's culture. For 99% of the time it's en-US, but on the first load of the MVC view after compiling it is set to en-GB. If I reload the page immediately after that, it's back to en-US.
I have tried setting the culture and uiculture in the web.config file to en-US to force it to be correct, but no luck.
I'm getting following error in Firefox while switching tab in the page Error: clientActiveTabChanged is not defined The following code I'm using in the master page
I'm making a new design for my website, but I want to keep the old one and possibly switch between the two.
Unfortunately, I've changed the content on the Master Page (luckily I have a backup). What I was thinking was to keep separate master files for each theme, and then just determine which one to server based on which stylesheet is loaded.
The only way I can think to do this is to keep a "settings" file on the website that has a "stylesheet=1/2/3/4/etc" line. Depending on the number there, the server will serve the correct master page.
Alternatively it might be easier to do something similar, but instead of serving a whole different master page, set a specific stylesheet to use.
I can read a text file (even encrypt/decrypt a file before and after it gets read for security), but actually giving the server the instructions based on what is read is where I'm lost.
i have a jquery tab. On each tab click i want to load a fresh page . I am using iframe, but while tab switching only the source is changed loading event does not takes place.
I'm having a bit of trouble with Paging within a GridView grid I have set up. I have added the paging but whenever I click on the next page or the last page buttons, the page refreshes and displays blank (i.e. no gridview but my regular search parameters are displayed.
I was trying to search for a solution throughout the web and came across someone that looked to have the same issue. He moved all of his queries into the Page Load method, and the paging seemed to work. I cannot do this because I have 2 different buttons: Search and My Order, both of which perform different queries based on if a date has been selected or what the search is on (Order Number, License Number, Description, Status, etc).
My paging method looks as follows:
[Code]....
From what I can tell this is an issue with no longer having the data set when making the paging call. Is there anythign that I can do?
I wonder if any of you guys could help me. When writing code occasionally I hit return to start a new line and the line is started from the far left instead of the same indentation as the line above like I would expect and when typing there is no intellisense, its happened a few times now

I am using partially secured pages ( SSL). Now the problem is when I am switching between HTTPS and HTTP, I am losing my session. I tried storing session in Sql Server Database, its still not working. I am using just ONE web server and all pages are in single application.I am using Sql server 2008 ,IIS 7.0, C#.Net 3.5 I created a self signed test certificate to test my application.
I understand that I am losing my session because my urls are changing with https and http but there has to be someway to overcome this problem. I dont want to put unnecessary load on pages which do not have sensitive data by using https.
I have a similar problem. I have one Dynamic Data Website and a thousand databases - one database for each customer. HTe databases have the same schema.
After the users log in I want the Dynamic Data Website to point to a database that belongs to that user.
I just completed the theme switching walkthrough on msdn [URL]/ms366514.aspx, and I want to expand this to convert the DropDownList into a custom control with either swatches or icons that can be clicked to switch the theme. It seems to suddenly become more difficult to work with themes when you change the scope. I found a couple of links online, one that used a global asax file to change the the theme but it didn't actually work.
I have an asp.net site that's basically a giant form for users to submit weekly turkey information for their starter and finisher houses. I use session variables so the information is viewable to a "Review" page. There have been 3 instances where the users would try to submit their information but kept losing their information. As far as I know, they are not letting the page sit idle for more than 20 minutes. I tested it out myself and lost session variables after less than 10 minutes. My sessionState mode is InProc. Should I look into switching to StateServer? If so, how would I do this?
