Hi all
How do i delete/remove a Querystring variable.
say Request.QueryString["ID"]);
i have tried this Request.QueryString["ID"].Remove(0) but it didnt remove it nor did it give an error message.
I also tried Request.QueryString.Clear(); and the error was the variable is readonly

i want ID in Request.QueryString["ID"]) to be zero so that
when i write code like this int s = Convert.ToInt32(Request.QueryString["ID"])
s will become zero, in other words i need to initilize the variable "ID" in the querystring.

hey i know its not good solution but i did it.
i hope dis will help u.
if (!Page.IsPostBack)
{
if (Request.QueryString["qstr"] != null) // if the query string exists
{
ClientScript.RegisterStartupScript(this.GetType(), "qr",
"document.all(\"aspnetForm\").action = \"YourPage.aspx\";",true);
RedrawPage(Request.QueryString["qstr"]);
}
}
Reasons are not Important but Results are Important.

QueryString collection will be populated on the page life cycle. You can't remove items from it. BTW, why do you need to remove a query string ?

I'm having a problem with datatable after i passed it to a function using byval in the page load. Inside the function I remove some of the rows that are not needed for that function. But i noticed that the original datatable rows in the page load was also deleted.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Dim ds as New datatable
Dim data as New datatable
'This part loads the data from the database using oracledatareader with a name "reader"
'Total datatable rows = 50
data.load(reader)
ds.Tables.Add(CreateOverall(data))
'Call the next function and pass the same datatable.
'Total datatable rows became 40
'Is byVal not working???
ds.Tables.Add(CreateDetails(data))
End Sub
Public Shared Function CreateOverall(ByVal record As DataTable) As DataTable
'I remove 10 rows in this functions
for i as integer = 0 to record.rows.count-1
record.Rows.RemoveAt(i)
next
return record.
End Function
Public Shared Function CreateDetails(ByVal record As DataTable) As DataTable
'Received 40 rows only
End Function
Anyone knows how to retain the original values in page load?
Thanks.

ByVal works perfectly - it is you who isn't... 
You pass a DataTable to a function, manipulate it, then pass it back - and are surprised to see your changes? What did you expect? If you don't want to see changes, pass it to a Sub (Procedure) instead of a funxtion. (Or simply pass back True or something instead of the DataTable)

Hello
In a website the result of students can be accessed only by their respective ID numbers! there is no other way to access the database. like the website shows a textbox with a submit button and the textbox only accepts a number i.e. the ID of student.
I want to grab all the result that is a way in which ID starting from 1 to 8000 are put in the textbox in a LOOP and data retrieved is SAVED in some file(a text or database file)...
so is there any way?

check this out! you will see the textbox and the submit button! I need to get to all the result! i dunno may there or some other simple ways but what i am thinking is if we start submitting numbers from 1 to say 10000 and store the data we get in a file? is it possible? or if there is any simple way to get all the result?

I might be wrong, but it looks like you are trying to get data from that site without their knowledge. We don't entertain such kind of practices here.
|
|

|

its not some illegal stuff!
i just said if there is some other way and didn't mean like someone hack their database!
I gave my idea like to do iteration! just like if someone sits and start giving ID himself, submitting it and getting the info and thn saving it by himself,,,, there should be a way to do it in programming or scripting! which ll be fast....

hi all
i have to display huge data around 1,00,000 records.
My client requirement is not to use paging.
so i have to display this data in one time.
i dont how to display this.
cud we use crystal report for this???

This can be done in different ways, it depends on how you get the source data.
1) If you can get the source data in XML format, then you can design an XSL and present the XML as such.
2) You can frame html with the source data and render the html to the page.
3) you can use Gridview or datagrid without pagination (but this will be slow).
The best method is the first one.

Im not sure if the number you meant to type was one million or one hundred thousand, but either way if somebody wants you to display that many records on a single page then they are idiots.
Firstly this is slow as hell, secondly no user wants nor needs that number of records in one go. ever.
|

|
|

its not recomondate to display this amount of data in web page, it will be very slow responsive page.
Better use some filter criteria by which you can at least reduce records.
cheers,

You can use any of the methods mentioned by one of the members in an earlier post. But the problem is it won't be efficient or feasible.
