i created a gridview with two columns and 8 rows dynamically. All the rows are empty and editable at runtime. I am giving column names for this grid from some other .aspx page by passing column names using querystring.Because i am using this grid for three different pairs of column names. i would like to know how to apply Required Field Validator, Regular Expression Validator and Range Validator on Gridview textboxes. So that by using those validators i want to validate user inputs. And i would also like to know how to add rows at runtime for this grid.
I am using ASP.net 2.0 and C#.net for this.(Visual Studio 2005)
I 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?

I am having two text box for "Password" and "confirm password".
The password should be minimum of 6 charecters.
when the password is minimum of 6 charecter it shows a error message and when the confirm password and password is not matching it shows the error message.
It displays both the error message at a time.
Is there is way to display one by one.

" <asp:RegularExpressionValidator ValidationGroup="vgProductDetails" ValidationExpression="^([a-zA-Z0-9]{6,10})$" ErrorMessage="Password Should be minimum of 6 Characters and maximum of 8 characters." SetFocusOnError="true" ControlToValidate="txtPassword" ID="RegularExpressionValidator4" runat="server"></asp:RegularExpressionValidator>"
For comapring the password and confirm password, i am using the following.
"<asp:CompareValidator SetFocusOnError="true" ID="CompareValidator2" runat="server" ControlToValidate="txtconfirmPassword" ControlToCompare="txtPassword" ErrorMessage="Password and confirm password should be same."></asp:CompareValidator>"
I have an application that I need the user to enter in a date and time: 10/16/2010 1:00:00 PM How can I setup validation to check to make sure the user has entered in the date/time in that manner? I can use the validators in asp.net to check for date and even when I create a custom validator I don't know how to tell if the user has entered the data correctly. I am adding this functionality to an existing system. So I can't change the text box into two fields for validation.
I have applied some asp validation controls on a page ,but on clicking Save button data is getting saved without throwing any validation . But as I am entering data for the next time and then click save button then it's working.
Is there a generic control that can be added to all aspx pages that checks for silverlight plugin and the version.. I know there is javascript and the silverlighthost object tag that accomplishes this. Is there an existing ascx control that wraps this functionality ? I need to be able to set the path to the xap on each page (via a property on the ascx control).

I'm trying to use required validation controls on two text boxes and tried using the following code:
<asp:TextBox ID="starttimeInput" runat="server" Width="130px" Height="23px"></asp:TextBox> <span class="style1">*</span> Start Time <asp:RequiredFieldValidator ValidationExpression="^([1-9]|1[0-2]|0[1-9]){1}(:[0-5][0-9][aApP][mM]){1}$" ID="StartTimeValidator" runat="server" ErrorMessage="You Must Supply Both a Start and an End Time" ControlToValidate="starttimeInput"></asp:RequiredFieldValidator>

I made a small program which tests a set of url's and checks if they get redirected to another set of urls. Now this program has been working fine till I got a few urls which are of the form [URL] Now the problem occurs when I have a url with "//" not the http://, whenever I use any url with "//" it produces the error The server committed a protocol violation. Section=ResponseStatusLine. If I test the same in the browser it loads the page, but I cannot check the same throught the application. If I remove the "/" then it should work, but then the site wont load.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Request.ServerVariables("SERVER_PORT") = 80 Then Dim strSecureURL As String [code]....
The validation load in this page worked on the first click of btnDonation, if I don't change anything and click the btnDonation again, it automatically go to my confirm page. Instead, I want it to continue to check for requiredFieldsOK(). Note that if I fill in one of the missing required fields, the validation will work.
My question is: How can I continue to check for requiredFieldsOK() even if user didn't fill out any additional information?
I have two validationsummary controls on my page for aesthetic reasons. Each control is assigned a validation group (StudentInfo and Grades). validation controls in the upper part of my page are in validationgroup StudentInfo and those in the bottom part of my page are in validationgroup Grades.
However, I only have one "Save" button control that causes validation. I want the Save button to validate both groups of controls, but it appears to only allow one Validation group to be specified in its properties.
Is there a way to have a button cause validation for both groups?

ow can I display multiple validation summaries at one time? I currently have three different validation groups on a page for different sections of the page. Basically, the first section should be validated by one validation group, the second section should validate both the the first and section section and the third should validate all three.I've got the following javascript which validates properly, but only the last validation summary is visible, the first two don't appear (but the red asterisks next to the controls do appear).
function ValidateSection3() { var validated = Page_ClientValidate("vgSection1"); if (validated) {
Using ASP.NET, I'm building an admin tool that requires a function to import a list of email addresses. Upon uploading the file, I want to check for existing records for any of the email addresses supplied. For non-existing email addresses, I would create them using my DAO.
Basically I want to:
Receive list of emails Retrieve data for existing emails Create data for new emails in db Return full data for all emails in list.
Since I want to know which of the emails exist up front, my first thought was to query the table for all records WHERE Email IN ('Email001FromFile', 'Email002FromFile', 'etc...') but the list could potentially contain thousands of email addresses, and I'm not certain supplying that many email addresses to the IN operator would be a good idea.
I also thought about looping through the list and checking for a record for each email, but that would potentially generate far too many queries.
My next thought was to generate a temp table to hold the list and modify the IN clause to use the temp table, rather than an explicit list of items, but that would require I execute SQL or a stored procedure directly, which I'm not inclined to do since I'm using NHibernate to access my DB.
I have a form that uses group validation with the following on btnDonation_Click. However, when I click btnDonation, the page comes back to itself even if everything is valid. Then, I click btnDonation again without changing anything, this is when the page will postback to Confirm.aspx. Do you know what might have caused it?
Code:
Protected Sub btnDonation_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDonation.Click Page.Validate("GiftValidate") If (rbContribType.SelectedIndex = 0 Or cbPrefHAddress.Checked = True) Then Page.Validate("HAddressValidate") ElseIf (rbContribType.SelectedIndex = 1 Or rbContribType.SelectedIndex = 2 Or cbPrefOrgAddress.Checked = True) Then Page.Validate("OrgAddressValidate") End If If Page.IsValid Then btnDonation.PostBackUrl = "~/Confirm.aspx" End If End Sub
