How To Insert Dependencies Dynamically In View (Javascript And CSS Files)
Apr 7, 2010
I am willing to follow the rules of the W3C where it is recommended that javascript and CSS files should be in individual files and not within the page.
Good, following this rule, and not wanting to overload the master page, I would like to embed the dependencies dynamically. So how could I insert the libraries dynamically? I think the bigger problem is the Ajax requests.
I have an ASP.NET application which requires output caching. I need to invalidate the cached items when the data returned from a web service changes, so a simple duration is not good enough.
I have been doing a bit of reading about cache dependencies and think I have the right idea. It looks like I will need to create a cache dependency to my web service.To associate the page output with this dependency I think I should use the following method:
Response.AddCacheItemDependency(cacheKey);
The thing I am struggling with is what I should add to the cache?
The dependency my page has is to a single value returned by the web service. My current thinking is that I should create a Custom Cache Dependency via subclassing CacheDependency, and store the current value in the cache. I can then use Response.AddCacheItemDependency to form the dependency.
I can then periodically check the value and for a NotifyDependencyChange in order to invalidate my cached HTTP response.The problem is, I need to ensure that the cache is flushed immediately, so a periodic check is not good enough. How can I ensure that my dependant object in the cache which represents the value returned by the web service is re-evaluated before the HTTP response is fetched from the cache?
My requirement is, i have a checkedlistbox, and i want the selected item should be inserted into the gridview using javascript, in grid i want only two columns i.e. selected item text and another is checkbox.
I do have a details view, which insert data to a database table using SQL Datasource. Now i need the data to be inserted in to 2 tables instead of one.
I am using Visual studio 2010 express and I have a details view databinded to an sql database table. When I use the Insert option on the view it causes an error due to it trying to insert a null into the primary key field. If the Insert function does not create a new primary key entry how is it created?
I'm being tasked with making changes to an asp.net application and really have no experience working with them other than dabbling in VWD.I was given a zip file of the directory containing the files. It was developed in VWD 2005. . My question is a general one: Are there steps I need to take (regenerate web.config file? change settings of some sort?) in order to get started? The application is functional on the web server.
I have a site that gets deployed to over a dozen clients. The main website has a base template, and each client has a client folder that overrides the colours. The problem is that there are a lot of CSS files, so making a change that forces us to update every client takes a long time. The automated build process takes care of replacing the updated files.
I would like to change the CSS files to be usercontrols instead, and those usercontrols could then inherit from another usercontrol where client specific values are stored.
So instead of having a forms.css file and then a /client/forms.css file I would have a Forms.ascx file that inherits from a usercontrol that contains the colours.
Ex:
[code]....
Then the masterpage would inherit from the usercontrol instead. This would make the maintenance of the client sites much easier.
If this is possible, would it also be possible to have the Forms.ascx control output the markup as CSS? Or make the extension .css and still have the ascx properties?
I tried to insert 3 xml files into database.But while i am trying to insert half of the value gets inserted after that i am getting error like
"Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached."
i have made an .aspx page of c# in folder named as "USERPANEL". Also placed all my js in "js" folder and css files in "css" folder & all these pages are placed under "USERPANEL" folder same location where i have create a page. If i would placing the css on the page itself then it's working but not loading any external stylesheets. why? below is code as i am attaching the fontawesome file placed in fonts folder.
I'm a bit new to .net so i was wondering if a thing like this is possible. I'm having one basic aspx script that needs to load some "plugins". Every plugin has its own settings and it should perform different logics. What i'd do in php is create a class for each plugin, load that class, pass the settings file to it and call some method on that class that would give me some output. But is it even possible in vb.net? I'd need to have multiple files with multiple classes, load those files, depending on the plugin name and call some method on them to parse that plugin's settings.
I am trying to create an "insert" row at the top of the gridview and have not had much luck. Most examples I have seen have been pretty complex. Does anyone have a straight forward way to accomplish this. Right now, I have added a "null" row at the top of my data that comes back and have been trying to hijack this line to add an Add Button but cannot get this to work right.
I am facing a situation wherein i have to ask the user for the files to upload and save them as blob in the database. I have a single file upload control on the page and user can add as many files as he wants. When the user browse the file and click add button then the file gets added at some temporary location on the page and later on when the user has specified all the files to upload then I would like to insert all these files using a single insert query in the database.
I am working on a application which supports multiple languages and I am doing it using asp.net resources files. Now the problem is, its a product and each user wants to have their own translations.For Example there is a text say "Home"Some users want to say it "Home Page" and some wants to say "Main Page"
Is there any possibility to do create different resource files, for each users, for each page and then load them according to the user currently logged in?

I have a view on my database and I am trying to add a new record using the AddTo method but it is not working. I noticed that LinqToEntities is creating the insert statement like this
Insert into (select field1, field2 from my_view) (field1, field2) values (value1, value2)
Is it possible to make LinqToEntities create the insert statement like the one below ?
Insert into my_view (field1, field2) values (value1, value2)
How to use cache dependencies in MVC?So far, I follow the caching tutorial (http://weblogs.asp.net/rashid/archive/2008/03/28/asp-net-mvc-action-filter-caching-and-compression.aspx) but what if changes occured in the database and the page is still cached. [:(]
How to clear cached pages when new data is inserted?
i was able to add a table dynamically to my form.[URL]
Now i need to grab the values and insert into the database. Below is the code used to create the table when a selection is made from a dropdown. My insert expects 3 parameters, ID, CamID, CamName
The ID will be from a field in the form, the CamID needs to be the "j" value below and the Camname to be the txtcam value.
How can I view pdf files within my documents? I came to know from a link that I can use Iframe to view pdf files. But it doesn't work. When the page is loaded, the download file dialog box shows up.
I developed a datagrid in my aspx page which was to show all the files present (with details) in a particular directory on my webserver. The column containing the name of the file in the datagrid is a hyperlink and when you click on it you could view or download the file.
Everything works great. When I click on the file name, it either opens up the file in browser or asks me to save it except the fact that when I click on a file name with extension .msg (outlook message file) it says - The Page Cannot be found
The page you are looking for might have been removed, had its name changed, or is temporarily unavailable..
The files are very well present there in the directory! Moreover, same everything was working absolutely fine (even the .msg messages) in my local system during the application development.
I dont know if sending the code makes sense in this situation - because code is correct and is working as it should be. It looks more of an issue with internet explorer or probably somerthing with Production web server configuration.
