View 6 RepliesI'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'm using a CustomValidator control to validate some controls in a GridView. I have the validation working perfectly on the client and the server, but would ideally like to pass the GridView ID into the client function so I can move it out into a separate
.js file. The signature for my client function is:
function valOrder_ClientValidate(source, args) { // Code here}
And my CustomValidator control looks like:

Is there a way I can pass an additional parameter into this function?
i've currently got a registration form that works fully however i've run into a problem getting the validation text to appear. basically i want the form to present the following message "Congrats you are now registered and can login using the login page" only if all the fields in it are filled in.

I have a web application (done in ASP/C#) that has regex validation on a text box. Initially the regex works perfectly fine. But then I also provide a button click event (clear) that allows the user the clear text box and change their input for a new query. At this point (page post back) the regex takes control and maintains control of the text box so a new query can't be run. Can anyone tell me what to do so that the regex doesn't fire on page postback and allows new input for validation?

I am trying to write a simple application that will allow a user to pass a value from the parent page to a textbox in an IFrame.
Parent Page will only contain 3 controls (label, textbox, and a button). Once a user fills in the txtbox and then clicks the button I want the value that was put in the textbox to be sent to a textbox within an IFrame.
IFrame will contain a label, a textbox, and a button. Once the value is passed from the parent's textbox control to the iframe I want to also fire a button event in the iframe that will simply be:

I've got a pretty simple problem but I am not sure what is the best way to accomplish this. I've got an input aspx where a user fills in about 15-20 input fields and I want to display this information on the next page however; I am not really sure what is the best way to go about doing this?
I tried using 'Server.Transfer' and 'FindControl' API calls but have struggled to use them because the value is always null because it cannot find the asp:textbox ID I have specified from the previous page.
What would be the best way to just simply transfer the values from my previous page to the next page??

I have a GridView which contains a set of trades bound to a SQL Server database table with a primary key called tradeId. I want to be able to edit a trade by having an edit button on the GridView. When the edit button is clicked for a record, I want to go to a new page called EditTrade.aspx page. This new page might have a DetailsView form in Edit mode and I want to populate it with the information using the tradeId from the GridView.My question is what's the best way to pass the tradeId to the page? Should I use Session State? Something else? I'm trying to learn ASP.NET and would like some advice on best practise.

I have a GridView and I need update some data inserting HTML CODE; I would need this data been stored encoded and decoded on request.
I cannot in any way disable globally "Request Validation" and not even at Page Level, so I would need a solution to disable "Request Validation" at Control Level.
At the moment I am using a script which should Html.Encode every value being update, butt seems that "Request Validation" start its job before event RowUpdating, so I get the Error "Page A potentially dangerous Request.Form ... ".
void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
foreach (DictionaryEntry entry in e.NewValues)
{
e.NewValues[entry.Key] = Server.HtmlEncode(entry.Value.ToString());
}

What is the best way to pass Values from one page to another in ASP.NET(C#)I am using a GRID and has EDIT column in it. So when user clicks on the Edit link the values of the row that has been clicked is passed onto another page (Edit form).Which is best way to pass values, considering some data may be sensitive User data.
View 5 RepliesI have 2 user controls that is hosted by 2 different aspx pages.
example:
srcpage.aspx --> hosts the --> sourceusercontrol.ascx
and
destpage.aspx --> hosts the --> destinationusercontrol.ascx
I would like the values in the text fields of the sourceusercontrol.ascx to be passed on to the labels in the destinationusercontrol.ascx.
I have gone through the MSDN ASP.Net examples and i was able to successfully pass values between two aspx page using the postback URL functionality, but cannot do the same thing with the usercontrols on 2 different aspx pages.
Scenario: a user must fill in some data in mutiple controls (textbox, etc) and after that all these values must be passed to a next page. The number of controls is defined in a database. This can be different each time so I need to find a way to dynamically pass values through response.redirect("page.aspx?var1=value1&var2=value2......");
