Data Controls :: Populate DataList Based On QueryString Value Throws Error When QueryString Is NULL Or Blank
May 7, 2015The 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.
No Querystring Logged In IIS Log On "A Potentially Dangerous Request.QueryString Value Detected"
Mar 5, 2010I'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 RepliesC# - Can Convert To The String But Can't Convert Back
Jul 30, 2010I have a string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.
DateTime d;
var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"};
if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d))
{
lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text
}
I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.

View 7 RepliesRequest.QueryString[] That Contains '+'
Jul 31, 2010I have a page that I wish to pass an ID in a querystring to another page
eg
Response.Redirect("~/Account/Login.aspx?CertificateID="+ CertificateTextBox.Text);
but the value in the CertificateTextBox is in the format of Encoding.UTF8
so it can contains character like "ZnbiS69F2g22OeupHw+Xlg=="
When the receiving page gets the QueryString
CertificateTextBox.Text = Request.QueryString["CertificateID"];
the "+" and possible other querystring chars like "?" are stripped!!
so I end up with
Request.QueryString["CertificateID"];
returning
"ZnbiS69F2g22OeupHw Xlg=="
the "+" strinpped!
Is there a way to encode these chars so they are not striped by QuesryString()or do I have to use a session variable??

C# - Get QueryString From A Href?
Jun 19, 2010I 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.
