View 3 RepliesI am working on ASP.NET3.5 platform. I have used a file upload control and a asp button to upload a file. Whenever i try to upload a file which contain special characterlike (file#&%.txt) it show crash and give the messeage "Server Error in 'myapplication' Application." A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.
Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. how can i prevent this crash using javascript at client side?
want to know that can we validate a control which is out side a form element in asp.net(server side validation)and outside a form element in html(client side validation) let's take a closer look
<html>
<body>
<input type="text" name="first name"/>
</body>
</html>
can we apply clien side validation on above text box by java script ?in asp.net
<form runat="server">
</form>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
I'm interested in identifying a means to verify the server-side validation is performing as expected, but need to bypass the client-side validation being done using ASP.NET validation controls. To test this, I've tried using the form Poster add-on to Firefox that allowed me to get/modify the page contents and post it, but the .NET framework interpreted the submission as harmful and threw an application error ("A potentially dangerous Request.Form value was detected from the client").I've created a WinForm that includes a WebBrowser control and I'm able to manipulate the contents of the web page and invoke the button click, but am interested in seeing how to allow a postback with invalid input values. I don't want to assume the server-side validation works (even though I do check if Page.IsValid on the server on postback).This submits the web form in the WebBrowseer control and the expected client-side validation fires:
extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");
This is how I've manipulated some of the page contents (this just prevents submission):
mshtml.IHTMLDocument2 doc = extendedWebBrowser1.Document.DomDocument as mshtml.IHTMLDocument2;
string html = doc.body.innerHTML;
html.Replace("Page_ValidationActive = false", "Page_ValidationActive = true");
doc.body.innerHTML = html.ToString();
extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");

I have a grid view with two columns...one column has a no. like (123) and a check box....which user can checked or unchecked......all I need to do is that I need to disable the man handling of that check box......rather I would like to see a seperate grid view with the same no. of rows as of the first and in this gridview I may allow to type in or scan the no. and if this scanned or typed number matches any no. in the first gridview number then the corresponding check box should be checked/unchecked.

An error occur something like this "Page.IsValid cannot be called before validation has taken place. It should be queried in the event handler for a control that has CausesValidation=True and initiated the postback, or after a call to Page.Validate. I make some work around but it didn't work
Here's my code in my Page Load event that an error occur
Code:
if (Request.QueryString["id"] != null)
{
txtID.Text = clsFunction.ReplaceString(Request.QueryString["id"].ToString());
if (!Page.IsValid)
{
Page.Validate();
cmdProceed_Click(sender, e);
}
}
In my page, I have this two validation group so if I am going to re-structure my above code like this
Code:
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["id"] != null)
{
txtID.Text = clsFunction.ReplaceString(Request.QueryString["id"].ToString());
Page.Validate();
if (Page.IsValid)
{
cmdProceed_Click(sender, e);
}
}
}
I will not encounter the above mentioned error however, my second validation group trigger and the cmdProceed_Click is not executed.

View 2 RepliesI have a form with x fields on - its a signup form on a web page. I use standard validation controls which I use for validating on both client and server side, however I have an additional requirement I don't think is covered by the standard controls. When a user enters an email address and press enter, I validate that the address is not already in the database, by calling a stored procedure. This works fine but it would be great to validate it client side as with all the other entry fields.
I wouldn't know where to start with javascript so I have come up with the following solution. I have put a ontextchanged event on the email textbox and set to autopostback. When the user navigates away from the textbox validation is called and this seems to work ok. My question is have I missed something, and is there an easier soluyion using validation controls or is this an appropriate solution to the problem?

View 2 RepliesIn my application the user uploads three files ( Resume, Cover Letter, Selection Creteria).
I want users not to upload more then 4 MB files, so In my web.confing file I have allowed max of 5 MB. <httpRuntime maxRequestLength="5000"/>. I did this so that I can validate the file and give user a message that they are trying to upload more then 4 MB file.
It all works fine if the user is only uploading resume. But if the user uploads all three files of size 4MB then my validation does not work and it goes to connection time out.
How can i handle the validation to check the file size of all 3 files?
