I am beginner of asp.net and c#Currently i doing appointment website and need suggestions/ ideas. I have create a simple web form with Calender Control as picture below enable users to select date and time. At the calender control, i have set that users can only select tuesday and thursday every month using DayRender. After that i put a DropDownList to display the time.Next step, i want to store the data into database, for example UserA make appointment on Date 21 September 2010, Time 1100 and make it unavailable for other bookings. When UserB makes appointment on same Date and Time, it will display information that the slot is booked/unavailable. To implement this, what approach should i take?

View 7 RepliesI 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.

I am having a big problem with the OnTextChanged event of a textbox....
I have tried several different scenerios and just don't seem to be getting it to work right...
I either get a full page postback which is not what I want or get a very peculiar extra textbox added to my page after OnTextChanged is executed...
currently the update panel is working as expected but it inserts an extra textbox into my form "magically"... so strange...the textbox that is added keeps a running history of what is submitted...you can take a look here at the behavior.. it is the email form in the middle of the page
Sample
Here is what I am working with...
[Code]....
and then in the code behind I insert a image to let the user know what is going on..
[Code]....
not sure why an extra textbox is added but everything else seems ok.....

I have a panel (say, panel1) inside another panel (say, outer-panel)….The panel1 is visible only when a checkbox is checked in the outer-panel. I am using ajax update panel to do this.
Now I have many text boxes in the panel1. I have to put a validation on all the boxes.
I tried to test this by putting validation on 2 boxes and this works fine on my local machine. When I put the same logic on the server, it does not. Of course the page on my local machine has fewer text boxes compared to the page on server. But I do not understand why the same logic works on my local machine and does not work on the server. I did try to put a validation group, but of no use.The page on the sever is a very long one and also it has a captcha control….. when ever I try not to enter text in one the text boxes which has validation and then hit submit…it redirects me to another page with out prompting for the validation error.
I have problem with validators in update panel. Tried to look for solutions in google but failed to find working solution. So this is my code (simple login panel):
[Code]....
When LoginLinkButton is clicked validators doesn't fire. I have no idea why :(. Tried with/without ValidationGroup, setting UpdateMode to always/conditional, removing triggers etc.
I am trying to verify if a username is taken or available by using jquery to send a request to an asp.net page. The ASP.net page is clearly getting the information as I am having it make an entry into a log database. My SQL server database indeed shows the username being passed to it and is returning a value however for some reason the client side html/javascript doesn't RESPOND to it. I am not sure if it is on the end of my html/javascript or perhaps my asp.net page is not returning the json information correctly? This is my first attempt at json The checking availability box shows up on the html page but it NEVER changes even when the sql server shows that it ran the stored procedure

View 2 RepliesI have MaskedEditValidator, which set u pt ovalidate datetime entry into text box. After that the button (html button input control )is pressed in order to start some process. Button is running the client side function (JavaScript).
Now in case of wrong input validator shows proper message, but how I can prevent button to be pressed and start the process. I.e. is it possible to check on client side the status of the validation?
Is there a way to get the modalpopup extender to only execute if all the validation = true on the same button. As soon as I tie the modal popup to the button with the validation check, the validation either doesn't happen or the popup displays and the validation works behind and that's not what I want.
