AJAX :: Change And Read Querystring?
Sep 5, 2010
upnlA: in this updatepanel I show search results based on querystring parameters
upnlB: here I have a checkbox list X which filters the search results (allows for narrowing the results)
Now when a checkbox in list X is clicked, I do an autopostback, then I need to update the querystring (current URL in users browser) and also update the search results.
I have no idea how I would go about this! Im seeing difficulties in changing the URL without doing a response.redirect/server.transfer and reading from the querystring to update the search results.

I need to have a video on my asp.net webpage, but the source of the video depends on a few of the querystring params. How would you approach this?
(Ideally I'd be able to control what video shows in the embeded section and if the embeded section is even present)

I think this is almost impossible but I would like to ask.
I have a dropdown in my page:
The Name Dropdown is combined with item name / manufacturer name
This is what I want to do:
When a manager select a name, The text on the dropdown change to only item name and read only. (example: 44 inch Side Brushes)
The Manufacturer Textbox automatically retrieves the manufacturer name and read only.

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.

I have two examples to show you what I want to achieve here. But to point what's different about my question, Is that I'm having a parametrized URLs and I want to implement URL rewriting to my application. But I don't want to convert the parameter in the URL to be placed between slashes..."page.aspx?number=one" to "pages/one/" << NOT!
First example:
http://localhost:1820/Pages/Default.aspx?page=2&start=5
To
http://localhost:1820/Pages/page2
Second example:
http://localhost:1820/Items/Details.aspx?item=3
To
http://localhost:1820/Items/ItemName
But I'll still need all the parameters in the original URLs

I wanted to know what this extra querystring data is and where it's coming from.
jQuery.ajax({
url: 'MyFile.aspx/ProcessRequest',
data: JSON.stringify({status: status }),
async: false,
dataType: 'application/json',
[code]...
Using tamperdata and also viewing the Request.QueryString in the debugger the resulting url is:
http://localhost/Folder/MyFile.aspx/ProcessRequest?_=1298057136790&{%22status%22:%22pqs%22}
So where does this _1298057135790 come from and why is it there?

I have a web form, and it appears that when I add the AJAX control toolkit on my webform, my Request.QueryString is clearing out. Here is what happens:
1) User clicks next on form 3, and I load up form 4 (form 3 passes query string to form 4)
2) User clicks next on form 4, and form 4 checks the query string that was passed by 3, and it's emtpy
This only happened when I added AJAX functionality.

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?

I need to set up the slide show based on a querystring parameter. I thought I had this figured out, but I clearly don't understand something about how the webservice works. I have this in the .aspx page:
<asp:Button ID="btnPrev" runat="server" Text="Prev" />
<asp:Button ID="btnPlay" runat="server" Text="Play" />
<asp:Button ID="btnNext" runat="server" Text="Next" />
<asp:Label ID="lblDesc" runat="server" />
<cc1:SlideShowExtender ID="SlideShowExtender1" runat="server" BehaviorID="SSBehaviorID"
TargetControlID="tstSlides"
AutoPlay="true"
ImageDescriptionLabelID="lblDesc"
NextButtonID="btnNext"
PreviousButtonID="btnPrev"
PlayButtonID="btnPlay"
PlayButtonText="Play"
StopButtonText="Stop"
Loop="true" >
</cc1:SlideShowExtender>
<asp:Image ID="tstSlides" runat="server" height="300px" Width="300px" />
And this in the code behind:.........................
