I want to remove Any added QueryString To Address after i get the variables. for example:
www.websiteName.com/page.aspx?a=344&b=233
i will get a and b and after that i want my address to look like this:
(www.websiteName.com) .
"root location".
I need to remove a querystring when a user clicks a particular LinkButton. So for example if the querystring is [URL] when the user clicks on the Linkbutton, I want the url to be [URL]. The issue is that everything is on one page, and I am using asp:panel to show and hide different areas of the webpage.

View 4 RepliesI'm looking for a way to get rid of the querystring of a page and redirect to itself but preserver the querystring data in some way. Exmaple: [URL] should redirect to [UL] Still, after the redirect, I want to be able to pick up the parameters that were originally passed. And I don't want to have [URL] in the browser's history.
What I tried so far:
* Response.Redirect(): does a proper redirect without creating browser history but I cannot preserver the parameters.
* Server.Transfer: preserves the parameters but the browser's URL remains unchanged.
* Create a client form on the fly and submit in "onload": works, querystring is gone, parameters are accessible through Request.Form, but creates a history entry in the browser.
The only thing I can currently think of is to store the parameters in the session, then redirect, then pick them up from there.
I need to remove an item from the check box list ("cblServices") based on the query string value ("serveytype").
I pasted my code here.
[Code]....
When the query string ("serveytype") = 1, some of the items in the checkboxlist "cblServices" need to be removed before it's being Enabled = true.
Similarly, when "serveytype" = 2, some of the items need to be removed.,etc..
The problem I am having is that I would like to open a new tab via a link button or link on my page. I need to append a query string variable from the page onto the end of the reference, because it is passing a parameter to a report.
I've successfully passed the parameter and opened the report in the same tab using this code:
protected void lbSummary_OnClick(object sender, CommandEventArgs e)
{
Response.Redirect("http://myreportserverURL&rs:Command=Render&Year="+YearID);
}
And I've successfully opened the report in a new tab without passing the parameter with this code:
<a href="http://myreportserverURL" target="_blank" class="menu">Report Name</a>
I would prefer to do both. One important note is that opening a new window, instead of a new tab, is not what I need. I do understand that this is somewhat dependant on browser use, but for this project I can assume that users will be on IE8.
What is the correct way to pick up a querystring variable that is passed to the page that the Silverlight Control is being hosted on?

Looking for advice on passing variables from page to page without using QueryString. The web crawlers such as google get caught up on the querystrings found in a URL. I'm trying to get away from using it. Is there another suggested method for passing the variables? I've thought about using session variables, but this is just for simply passing the variable from page to page and they won't always be the same.
On another note, I can't do it using forms. I'm using a master page with a form embedded in the master page and also the content pages. Unless microsoft updated it so you can multiple forms on one page.
How can i use querystring for this-
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?
[Code]....
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:
<FooterTemplate>
<asp:Label ID="lblEmpty" Text="No Result" runat="server"
Visible='<%#boolean.parse(([b]list[/b].Items.Count=0).ToString())%>'>
</asp:Label>
</FooterTemplate>
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.
Response.Redirect("mypage.aspx?ID=xyz&sex=male")
I know the querystring is 'ID=xyz&sex=male', where ID is the first key and sex is the second and xyz is the first value and male is the second to the respective key. But can't I use a variable in place of a regular string 'value', like this:
dim str as string
str="xyz"
and use this str in the 'value' part of the querystring above as: Response.Redirect("mypage.aspx?ID='str'&sex=male")?
Passing Variable from page to page using ASP.NET (C#) without using QueryString
The difference in my case is that the request is coming from a different website (in java) to my website (in asp.net). I do not want the variable to appear in url.
To explain my scenario, we are making a webpage(plugin), which can be called from any other website. To authenticate request, i am looking for a mechanism when other website will pass id & auth-key to my page. This i can use to authenticate the request. I do not want these variable to be visible.
I'm intermittently seeing this exception being thrown:
A potentially dangerous Request.QueryString value detected
However when I look in the IIS logs I can see that the request that failed has no querystring logged against it.
How could this be? Are "dangerous" query strings being stripped from the log or something?

View 1 Repliescan we grab a global variable or Session or View State variable in the javascript or using jquery?
I have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.
I got a variable of type System.Drawing.Image and need to convert it to a variable of type byte so I can store the image in the database. Can someone show me how to do that in VB.NET code.
View 2 RepliesI'm evaluating two options of accessing a server side data on client side. Little bit confused about the efficiency or may be you can call it as finding best approach to do it.
I need to access a server side data may be an integer value in javascript on client side. I know about two options to do it.Create a public variable or property on server side and set it to javascript variable on client side as below:
var value = eval(<% =value %>);
Create a asp hidden variable and set value in this hidden variable from server side and access it through javascript using document.getElementById().
Which is the best approach and what are the pros and cons?
