C# - Passing Values Across Pages?
Apr 7, 2010
i need to pass a long list of Ids from one page to another, i was thinking of using querystring but taking in consideration that the number of ids to be passed may reach 300 i think is not a good idea.an option from my understanding may be the use of session, this seems to me an optimal solution in my case but on the other hand I can certainly clear the session when the user performs a certain action and the list of ids is not longer needed, but if the user leaves the page without performing any action i want to clear the session, how can i do it?f multiple users are using the same functionality do i need the session's items to be confused or the session is for a single user?

I've done my homework, I've read a lot of articles, I searched and searched but still couldn't find my answer and it's kind of getting on my nerves because there's a very popular question all over the blogs and websites and it's just the same as mine, the difference is the answer is not what I want!
To be clear, the two pages are only logically related in other words the values in my FirstPage.Aspx pass values to my SecondPage.Aspx so it control components and certain attributes of the controls in my SecondPage.Aspx, the SecondPage.Aspx is not a redirect or transfer from FirstPage.Asp.
Consider the firstPage contains a textBox which get a value from the user or the web admin to set his preferences about the gridView page size on the SecondPage or a Text property of a label on the SecondPage
I want to explore my options to do so
PS: I was told to use a database to store values from the first page then on the page with my Label for example I connect to the database and retrieve the value and set it to the label...is this a best practice to let the page connect every time it loads to set some values somtimes it's just an int like 5, and most of the time I'd be connecting already to the database to display some table's data in a gridView or any databound control!

I wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.
So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.
So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"
Is there a way to resolve this issue? may be Dictionary List?

Have tried the redirect with an ampersand in the middle but that does not work either...
Response.Redirect("Page2.aspx?Value1=" & Value1 & "&?Value2=" & Value2)

I have a project which contains a header page (header.ascx) included in a main page (page1.aspx). the header has a dropdown list. the main page has a code behind page (page1.aspx.cs) which calls a data page (data.cs) which in turn calls a query page (query.cs). The problem is that I need to get the selected value of the dropdown from header.ascx over to query.cs and write it into a variable. I can't seem to reference the control itself, so I added a session variable to the selectedindexchanged event for the dropdown, but I can't seem to reference that variable either.
1) what is the best (performance-wise) way to pass the value (which will have a dash in it, like '1-114' from the header page to the query code?
2) are there any specific using statements or such that need to be added?

I have an application that uses DataContracts/DataMembers and Serialization to store information entered in a tab control. There are 8 tabs in the control (therefore 8 aspx pages). The final tab is used to write the information to disk.I am trying to understand: When should serialization be used in a web app? The objects are stored in memory not on disk. Is this another means of passing objects between aspx pages? If so when should serialization be used vs. session objects? How long is the serialized object retained in memory?Can I get a simple example of how to serialize in one page and deserialize the object in another page?I've read many blogs regarding serialization but have yet to find a simple example and none of them explain when serialization should be used vs. session objects?

I am using session variables to pass the form data. I have the server control Enableviewstat as true, but it still doesn't work. What else should I do? My code as below:

I have a number of drop downs that the client can select a range of criteria. From this, they will press a button, the query will be generated and low and behold, a gridview will be produced in a new window (or at least give that impression) bound by an object datasource. I would also like the user to be able to amend the search numerous times so they can generate a number of new windows/gridviews.
Now then..what would be the best approach for achieving this result?
My initial thinking was to create a querystring generated by the client criteria selections (in the drop down lists), a new page would then take the querystring and populate the gridview here. My concern with this approach is that the query string could be a whopper...are there any disadvantages to creating a ridiculously long query string?
Alternatively, are there any other methods or ideas people have used to produce a similar desired effect?

I have a web page that contains a GridView which the user is allowed to "Edit", "Delete" and "Select" rows. What I'm trying to accomplish is when a user clicks on "Edit", they are redirected to another web page that contains a DetailsView of the record they selected from the GridView (previous page). How do I make the association?

I am creating a DataSet to attach to a report (*.rdlc). In the DataSet is a TableAdapter that has the GetData(@start, @end) function. Can someone please explain how I get values in to @start and @end? I have searched and seen that it might have something to do with overriding the Fill function in the DataSet code behind file. Please let me know.
