C# - Alternative To Query Strings To Pass Data Between Webpages?
Jan 20, 2010
I am currently using a number of query string parameters to pass some data from one page to a second page (the parameters hold confirmation/error messages to display in the second page), that due to a third party product can no longer work correctly in the production environment. The user completes an action on the first page, and is then transferred to the second page. What are the possible alternatives to use instead of a query string and GET - session variables, POST data, or something completely different?
Unfortunately, when the new webpage opens, the url contains lots of spaces and I'm struggling to remove all of the spaces. The code actually works but looks a bit messy, see below.
Using Vb.net I created a html table with a hyperlink column to another ASPX.Net page. The page I am linking to has a text box that accepts a customer number and a button (NEXT) to link to another ASPX.Net page. When I link to the first page, the customer number is not in the textbox. Also, I do not know how to execute the NEXT button so it links to the final page.
I can get the current value of a URL query string by using Request.QueryString["UrlKey"], but can I actually modify the URL with code, without doing a form GET submission?
If the user is landing on the page for the first time, what is the easiest way to programmatically create the ?UrlKey=value through the Page_load method? Or am I better of doing this with Javascript or building a redirect Like: string redirect = "www.mysite.com?" + MyKey + "=" + MyValue;
What I have is a table that holds 3 input elements, They represent order, name, value. The user can add a new row of 3 inputs to add as many of these sets of data as they want.
To accomplish the dynamically adding in of inputs I use jquery's clone method. That works fine and I am able to iterate through each and grab the values, however the real pain I am having is that when the user has entered in all of the data I want to pass that data to an asp.net page through jQuery's post method. How do I go about passing an array of strings so that I send this format to the asp.net page, and when I've done that how do i parse the data on the asp.net side of it.
Desired Data Format:
["Name|Link|Order", "Name|Link|Order", "Name|Link|Order"] jquery Code so far: $("#saveBtn").click(function (e) { e.preventDefault(); $("#addPanel").slideUp(300); //Perform Save Operation var saveString = ""; $("#addTable tbody>tr").each(function () { var o = $(this).find(".hsaorder").val(); var n = $(this).find(".hsaname").val(); var l = $(this).find(".hsalink").val(); saveString += n + "|" + l + "|" + o ; }); ////// Create Array here or some other method? $.post("/modules/H/Modify.aspx", { OBVIOUSLY SOMETHING GOES HERE}); // Remove all but top table element to return to original state $("#addTable tbody>tr").not("#addTable tbody>tr:first").remove(); });
I have alot of query strings on one of my seartch pages. The problem is that even if the corsponding setting is not set by the enduser it will be visible in the URL. Is there a way to avoid this?
In this case the Controller actions take an object of the following class :
[Code]....
Is it possible to avoid setting all the values in the URL when it is the default values that are used?
I'm pretty new to C# and ASP.NET, so bear with me on this one. I'm setting up a page that receives query strings from the url. It then passes these strings to another method (in another class, actually), which goes on to do lots of things depending on the value of the query string.
The general structure looks something like this, where DoSomething() is actually part of another class that will be used by lots of different pages:
pretected void Page_Load (object sender, EventArgs e) { DoSomething (Request.QueryString["name"]); } public void DoSomething (string UrlVariable) { // if UrlVariable isn't set, initialize it to some value // do stuff with UrlVariable }
Here's what I'm wondering:
If the query string "name" isn't defined in the url, what does Request.QueryString return? an empty string? null? If it returns null, what happens if I try to pass null to a method that is expecting a string? Does the whole program fall apart, or can I check for null inside the DoSomething() method (after receiving the null string)?
The "name" is optional, so if the user doesn't set it, I'd like to detect that and initialize it to some default value. If possible, though, I'd like to put any validation inside DoSomething(), instead of doing the check on every page that requests the string.
I am attempting to pass a text box value into a SQL query, something which just does not want to work for me. The error I receive is 'End of statement expected.'
I presume it is a syntax error on my behalf, I am brand new to ASP and would be grateful if someone could point out where I am going wrong. Below is the code that is causing the problem:
I am able to insert hard coded value into the database using this statement so I know that my database connection is not a problem, therefore I presume it is a problem with possibly the concatenation or the way I am referring to the text box.
I have a query that I am passing to a new page. It seems that when the querystring is too long I get it diagnose connection problem page on internet explorer. Could there be a memory issue or something. When I reduce the amount of records being queried it seems works.
I am trying to creat a page where the user enters text in a textbox, clicks a button which goes to another page that displays a gridew based on the value entered in the textbox. i know this has been done a million times but for whatever reason I can not figure it out.
I wanna to pass query in a dynamic link button. I can add it dynamically but unable to pass query on that. Apart from that LinkButton_onClick handler is not working.
sales.aspx.vb Custom function which stores the current DATE into todayDate. I use this function to convert system date into SQL friendly date. sales.aspx I used Data Grid and SQL Data source. SelectCommand="select * from sales where aab = 110026" I want my select statement should take the date from todayDate. i.e.: SelectCommand="select * from sales where aab = todayDate" How to write this statement in correct syntax.
I tried to develop a dynamic pivot query with following code to avoid hard coding. I can got the 'Q1, Q2, Q3, Q4' dynamically and assigned to @(@quarter. But it cannot be passed to the pivot query.
I have a label control in an aspx page, can i set value to the label from an handler file? How can i pass the reference of the label through query string?
SELECT * FROM [vw_aspnet_MembershipUsers] WHERE ([UserId] = @UserId)
When I pass simple GUID like "3bd08871-d5d6-4f38-8c8a-29fd6077a719" as a UserId, then nothing gets selected. So what is the correct format for passing the GUID value?
