Efficiently Get All Client Form Data For Manipulating During Raisecallback
Sep 9, 2010
I'm trying to get most of the data I have on my web page, to update a query during an asp 2.0 raisecallback event. I've tried Request.Form with no luck. I've got the html (sent in raisecallback parameter) using 2 div tag's innerhtml. Can someone tell me an efficient method to use to get all this data for updating - Do I have to parse from the callback string (eventArgument) & if so can I use a reader of somekind, or is there a better way?
i'm currently learning .Net and i can get data out of a database and display in a listview. But how can i access data items in the code behind and format, change, concatenate...do whatever i want to them then display in the list view? Is it even possible?
[Code]....
Maybe an example of what i'm trying to do would be to concatenate a address from the dataset and in a variable sAddress and then attach sAddress to a label in the list view, or add to colums of the dataset together and then show in a label in the listview.
I have a grid view attached to a custom query. The query selects data and the address data in the database is split into different fields like street_address1, mail_zip etc. etc. What I would like to do is display all the address data fields in my database in one field on the Grid View.
When I click submit, It does the validation on the server side, I kinda like it to validate on the Client instead of taking a trip to the server right away.
So, in our website we are using SiteMap. For each request we render some menu and to do that we do SiteMap.RootNode in the helper function.
Now, when I have done the profiling of my website using dotTrace, I saw the get_RootNode() is taking lot's of time(around 70-75 millisecond). But we know that the SiteMap is static. So, I am thinking in somehow I will get the SiteMap.RootNode only once in Application_Start and will access that through out each request.
So, my questions are,
Is my approach correct?
How should I do that?
Or is there any efficient way that I can use SiteMap.RootNode
I created 2 functions that do this, but I do not this it efficient at all. I have a 40mb file and it takes the program about 2 hours to complete. Is there a more efficient way to do this? Is there a way to use regex? See my code below:.....................
I have a parent/child relationship that I'm currently pulling via the EF .include() method and displaying via two foreach loops in my view -- the first foreach loop is for the parents and the second is nested inside each parent and is for the children of that parent.
This has worked fine, but now I need to display information about each child that is not contained in my main child table. The table that contains this extra information only has a relationship to the main child table and thus there is no association between this table and the main parent table --- i.e. the .include() method can't pick this up. I've looked, found nothing and thus assume that I can't have two .include methods chained together. (even if I could, would this be efficient?)
I know I can perform a simple join and pull all of the child information with the parent records, but that would create issues with my paging because I want the page size determined by the number of parent records displayed. For some parents, there are only two children; other parents may have 10 children. So a simple join would create records where the parent information is duplicated and would throw off the paging.
Ideally I'd like to pull the parent information and pull the children information and connect the two when the view is populated, but I don't have a clue on how to do this efficiently (if that's even possible).
In my web application I am working with files. Some files are very large. I use Response.Write() to write the file to the browser. This goes well for the smaller files, but for large files this can take a while and the bandwidth is fully used.
Is it possible to split large documents and send it piece by piece to the browser? Are there other ways to send the document quicker to the browser?I hold the document as a property of an object.
I've got a database table with a very large amount of rows. This table represents messages that are logged by a system. Each message has a message type and this is stored it it's own field in the table. I'm writing a website for querying this message log. If I want to search by message type then ideally I would want to have a drop down box listing the message types that have come up in the database. Message types may change over time so I can't hard code the types into the drop down. I'll have to do some sort of lookup. Iterating over the entire table contents to find unique message values is obviously very stupid however being stupid in the database field I'm here asking for a better way. Perhaps a separate lookup table which the database occasionally updates listing just the unique message types that I can populate my drop down from would be a better idea.
The platform I'm using is ASP.NET MVC and SQL Server 2005
I have an ASP.NET app that accepts users comments and them in a SQL database. I want to make sure that I weed out any "naughty" words so I can keep my app respectable. Problem is that I'm finding there are LOTS of these words. ;>My question is, what's the most efficient way to do this processing? Should I have a table in SQL and write a stored proc that does the work? Should I do it with c# and Regex in memory on the web server? Are there other options? Has anyone else successfully done this kind of text scanning at scale? If y, what worked?
My requirement is something like what's shown in the below link
[URL]
i.e. Say 3, 4 and 5 are user id's. The middle column can contain some information about that user. Say for User 3 we have Info 1, Info 2 and Info 3 in those three rows. Similarly, for user 4 and 5, we would have some values in the middle column.
The number of rows in the middle column can vary. It depends on the number of rows returned by the DB call for that user.
So, how can I achieve this using grid view?
Will it be possible for me to add rows in the databound event dynamically by looking at the previous or next row in the datasource? If so, how should I go about it?
I am building a quiz application which has 5 categories. I am saving details like name, category and score to DB. Table where all data is saved looks like :
Name Category Score John Windows 10 Tom Mac 5
On the start page i want to disable/enable categories if user has/has not took quiz yet (ie. if John has already completed Windows quiz but hasn't Mac then enable Mac Quiz, disable Windows and show Windows score).Whats the most elegant way of retrieving these values from database and then passing them to variable or boolean? What if search returns NULL (if quiz was not taken by John) and manipulating output from SQL Database? I am using vb.net 2.0 and SQL server 2005 and its an asp.net application.
In this asp.net web application, users can upload files to the server through a web interface. All the uploaded files are save in a server side folder. If I want to create a new win form desktop client (actually, its a WPF application) which can be used to upload files to that same server side folder as web interface does, how can I share that server side folder with that win form client?
I am fresh new to asp.net. I try to convert my windows form into asp.net application. On my Windows form I use threads to monitor for changes in data sources to udpate my controls.However, I got no clue how to accomplish this in asp.net form. It seems I cannot create a thread in the page to update my controls in the page.
Although I'm a total novice at building web pages, I figured the best way to learn is to do it. I've used a master page and, so far, all the basic information pages work OK.
My problem starts when I have several options for the same Content Holder. Is it possible to use clickable cells to show various *.html files in a different row in the same table.
I can show an image using a script but not a file.
<script type ="text/javascript" > function Change() { document.getElementById ('tdContentItem').innerHTML ='<img src="Images/Thumbs/Councillors.png"/>' } </script>
What I need to show is a clickable imagemap that loads the resulting pages into the same row.
I was recently assigned a task of changing our asp.net web site localization to use custom resource provider (using sql database) instead of the default asrx resource files. Right now I'm chalenged with replacing hundreds of meta:resourcekey="resource-key" with '<%$ Resources:[filename,]resource-key %>' in our web site too many web pages. I want to do it programmatically.
first of all I'm not able to open .aspx files using XmlDocument, then I wonder how can I read meta:resource entries inside the aspx file as meta:resource is not any regular node attribute. any thoughts or example code how to solve this.
Note: in the inserted '<%$ Resources:[filename,]resource-key %>' filename name sould be based on the aspx file name & resource-key on the control type and the resource value.
exemple: in UserPage.aspx page <asp:Label id="uid" meta:resource="userName"> should be replaced with <asp:Label id="uid" Text='<%$ Resources:UserPage,LBL_userName_text %>'.
I am trying to manipulate the XML of a Word 2007 document in C#. I have managed to find and manipulate the node that I want but now I can't seem to figure out how to save it back. Here is what I am trying:
// Open the document from memoryStream Package pkgFile = Package.Open(memoryStream, FileMode.Open, FileAccess.ReadWrite); PackageRelationshipCollection pkgrcOfficeDocument = pkgFile.GetRelationshipsByType(strRelRoot); foreach (PackageRelationship pkgr in pkgrcOfficeDocument) { if (pkgr.SourceUri.OriginalString == "/") [code]...
I have one asp.net application, which has some problems while i am entering the special characters such as ": &#, " in the search box. If i enter this text in search box, i got the exception like this. A potentially dangerous Request.Form value was detected from the client (txtValue=": &#, ").
then i searched on the net, i got one general solution for this that to set the validaterequest to false. But no changes has been made on my application.
I am currently building a web project in which I would like to allow the user to navigate using either the back/forward button I created or the back and forward buttons in Internet Explorer to navigate my project.
On my website navigation, I have a link to a registration page. The issue is, I only want that link viewable when the user is not logged in.If the user is logged in, I want that link to disappear from the website navigation.
I am having problems in manipulating excel files in vs2005. All I want is to get the excel files(this excel has specific design for reporting and has macros in it), read it, add data for reporting purpose, and make that file send to the client. Now, the problems I encountered and will encounter is:
1. It has password protect, I dont know how to unprotect it. I already use sheet.Unprotect("password here") but no use.
2. Actually I cant read this using Microsoft.Interop method.
3. Call every sheets I want to be updated.
4. Update the cells with data from database(getting database data is easy of course)
All the date values on my website (whether from DB or returned by DateTime.Now) are represented in the format of mm/dd/yyyy hh:mm:ss AM/PM, even though the database values of the dates are not that way at all.I want to change the format of all the dates to dd/mm/yyyy hh:mm:ss without AM/PM.
