C# - How To Get Value Of A #t=querystring In Asp.net
May 19, 2010
I use Request.QueryString["var"] to pull the value of http://test.com/test.aspx?var=test into a stringthe same thing doesn't work for test.aspx#var=testhow can I get it from that version of a querystring?
Here in below code i have used querystring for sending imagename from this page to another page. Now i just want that with this imagename in also want to send span element's text with same querystring.How can i achieve this?
The following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid() Dim id As Integer = Integer.Parse(Context.Request.QueryString("id")) Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString Using con As New SqlConnection(strConnString) Using cmd As New SqlCommand() cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"
[Code] ......
However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.
From gridview i use querystringparameter "title" to open new page and show in detailsview the selected data. It get it right. In the detailsview page i want to show also data from another db wich also have "title". Since i use querstring parameter for the first data, how can use the same querystring for the second?
The first time the user navigates to my page there will be no query string in the url.
The page will display them 10 posts, and at the bottom there will be a 'next page' button that will call the same page but this time pass the page a pageNumber in a query string and the next ten posts will be displayed.
how can I detect if there is a QueryString in the url so that only when the page is called by the 'next page' button and there is a QueryString is my code exicuted?
I have a datalist that I want to list the Products that are comming from the Querystring. It works like this: Default.aspx/?ProductID=1 I get 1 product like I want.But I want to add more products like this Default.aspx/?ProductID=1,15,25 and get three products back. How do I make that to work?
I am trying to get the QueryString value like this Request.QueryString("SYSTEM") from a UrlReferrer. I see i can use this Request.UrlReferrer.Query() but it doesn't allow me to specify the exact parameter I could parse the Query() value, but I want to know if it is possible to do something like this Request.UrlReferrer.QueryString("SYSTEM")
i want to know how to hide the values in query string in ASP.net. here i want to send the values from one page to another page through query string with out explicitly visible the values in the query string. i want the solution with the response.redirect method. example : [URL] but i wan the link is [URL] only. I dont want use Session, or cache.
I am trying to stop XSS attack so I am using html agility pack to make my whitelist and Microsoft Anti-Cross Site Scripting Library to deal with the rest.
Now I am looking at encoding all html hrefs. I get a big string of html code that can contain hrefs. Accours to MS Library they have an URL encode but if you encode the whole URl then it can't be used. So in the example they just encode the query string
UrlEncode Untrusted input is used in a URL (such as a value in a querystring) Click Here!
[URL]
So now my questions is how do I parse through a href and find the query string. Is it always just "?" then query string or can it have spaces and be written in different ways?
Edit
This urls will not be written by me but the users who will share them. So that's why I need a way to make sure I get all query strings and not just ones in valid format. If it can work invalid format I have to grab these ones too. Hackers won't care if it is valid format or not as long as it still does what they want.
I'm getting date value from calendar pop up window to the parent page but when my parent page gets postback that date value is being removed. anyone knows the solution, i'm using 2.0
The homepage of an ASP.NET Web site that I am servicing contains a link to an ApplicationsGroupList, listing all of its applications. Clicking this link takes the user to an Application Group page, where specific applications reside under this particular group.
In C#, how can I create the ability for an enduser to link directly to an application group page by passing the Application Group name in the querystring?
I stucked at a condition , where i need to share values between the pages. I want to share value from Codebehind via little or no javascript. I already have a question here on SO , but using JS. Still did'nt got any result so another approach i am asking.
So I want to know can i pass any .net object in query string. SO that i can unbox it on other end conveniently.
Update
Or is there any JavaScript approach, by passing it to windows modal dialog. or something like that.
What I am doing
What i was doing is that on my parent page load. I am extracting the properties from my class that has values fetched from db. and put it in a Session["mySession"]. Some thing like this.
Session["mySession"] = myClass.myStatus which is List<int>;
Now on one my event that checkbox click event from client side, i am opening a popup. and on its page load, extracting the list and filling the checkbox list on the child page.
Now from here user can modify its selection and close this page. Close is done via a button called save , on which i am iterating through the checked items and again sending it in Session["mySession"].
But the problem is here , when ever i again click on radio button to view the updated values , it displays the previous one. That is , If my total count of list is 3 from the db, and after modification it is 1. After reopening it still displays 3 instead of 1.
