I've added some validation to a text box which works, only the code behind on the image button executes even if the validation shows a problem. I need some way of testing the validation and blocking the code behind from running. He's my code:

An outside vendor did some html work for us, and I'm filling in the actual functionality. I have an issue that I need help with.
He created a simple html page that is opened as a modal pop-up. It contains a form with a few input fields and a submit button. On submitting, an email should be sent using info from the input fields.
I turned his simple html page into a simple aspx page, added runat=server to the form, and added the c# code inside script tags to create and send the email.
It technically works but has a big issue. After the information is submitted and the email is sent, the page (which is supposed to just be a modal pop-up type thing) gets reloaded, but it is now no longer a pop-up. It's reloaded as a standalone page.
So I'm trying to find out if there is a way to get the form to just execute those few lines of c# code on submission without reloading the form. I'm somewhat aware of cgi scripts, but from what I've read, that can be buggy with IIS and all. Plus I'd like to think I could get these few lines of code to run without creating a separate executable.
I have a sign up page in my website where the user needs to enter his email id.Now i want to check whether the email id entered by the user actually exists or not...
View 18 RepliesI've always been a bit unsure how to check for the existance of properly referenced table data.
In my situation I have various tables related to each other in many-to-one relationships where the "1" side can be deleted without the reference fields on the "many" side being updated (nulled).
I have FK relationships set up in my MS SQL server database but have turned off the FK constraint enforcement (and cascading update/delete) so that I can delete records from the "1" side but leave the keys for those deleted records in the records on the "many" side. This is something I really need to do for my web app design.
how to protect form action if form is not valid based on javascript validation in mvc?
View 5 RepliesI'm populating a DataList using the IDataReader object and it works fine it the reader contains data. If the data is not present it displays nothing. I want to capture that situation and insert a verbiage such as "No data" or something like that. I've tried to test the datareader for various conditions such as Null, String.Empty, or plain " " but nothing worked. Is there a way to make this happen? Below is my code sample for your review.EJM.Note: It has to be done programatically as I'm building this for a web part.

how to open a subform model Form,Sub Window form using jquery that save the data ajex
View 4 RepliesIn my application, if I do not input the value into the textfield, it will show error message: "The value '' is invalid."
However, is it possible to check one more thing: the length of the textfield? For example, it will show the error message if I input more than 10 chars? And is it possible to change the message "The value '' is invalid." to "Missing Value"?
I have a form that when submitted shows a busy animation and disables the submit button.
Anyone know how to query Microsoft's Sys.Mvc.FormValidation to see if the form passed it's test so I can prevent the busy animation showing if the form hasn't actually been submitted? Or even some other work-around? In case it's relevant - I'm using Data Annotations for my validation.

I have a gridview which has bound fields and a template field for checkbox.I wrote a code for deletion of records as per checking checkboxes.My problem is
HtmlInputCheckBox chk;
foreach(GridViewRow dr in dgvdetails.Rows)
{
chk = (HtmlInputCheckBox)dr.FindControl("ch"); [code]...
I have some code which connects to a port quickly and if it can connect then it turns the line in the gridview green, if it cant and times out then it turns the line red. This is great, the problem i have is that the page takes a long time to load (as it has to check each port first) and then if i want to check again if the port is up / down i have to manually refresh it which is not what im after.
[Code]....
The code is in a loop and cycles through the various ports in the DB, what i want to know is how i can write a loop that will going through each port without waiting for the last port to come back with a result
Secondly do this in some way that it will auto refresh every 30 or 60 seconds without having to refresh the whole page.

Even with https enabled, you can write a password to the event log in code-behind. Any way to keep that password encrypted in code while you're checking it against a data store?
(using Login control)
(couldn't add comment to Andrew's answer, so I'm putting it here)
NTLM uses the username/password of the machine the user is logged into right? For this, I was thinking using ActiveDirectory on the server as the data store. It would have a diferrent un/pw than what the user is currently signed in to their machine as.
