[code]....
now look at the Elseif part, if the textbox is greater than and the user has pressed the return key(Enter) then it should execute the do whatever condition. i could do this on the client side , but my app requirement has changed so some of the code is on the server side.

View 5 RepliesI have an aspx box with with to asp controls; one text box for entering a password and a button for submitting. Now, when the user enters a password he has to click the submit button.
I want to set it up so the after the user enters a password all he has to do is hit the enter key on the keyboad instead of having to click the submit button. I want it to work just like it does on this forum; all I have to do is enter my user name and password and hit the enter key on the keyboad. The only difference is that I only have a password field and not a user name field.
I tried setting the password to autopost back and it didn't work or at least I didn't have the code correct.
I am calling a javascript for a textbox when a key is pressed to check for the Enter key. It works for all other keys though. The problem is I have buttons on the page also and the first button is taking the Enter as a click. If I disable the buttons, it works with the Enter key but I need the buttons there.
Is there any way I can keep the buttons from accepting the Enter key in a textbox as a Click?
This is what I set in the Page_Load which works well. And the script is called.
Code:
Text1.Attributes.Add("onkeydown", "check_key(event)")
I have a textbox added in an item template so I can enter data. But when I press enter in a textbox it caused the page to postback and I lose the data entered. I can tab through fine but why does Enter cause a postback? Can I disable this?

I use FileUpload to select a file and then I click an Upload Button to read the browsed filename. When I select a file that is larger than the max set in web config, my app crashes. The click Upload Button and the FileUpload control are in an ItemTemplate in a Gridview. If I select a file that is less than the max allowed, everything works fine.
How/where do trap this kind of error? I have tried breakpoints in my code behind, but it seems like the page crashes before any of the events I have tried to trap. I have tried a customvalidator to no avail.

I have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
I have to use C#.Net and JavaScript.
Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).
I reordered some items in a listbox using Javascript. When I read the items in a postback in the code behind (ASP.NET), the order is in the original order. How do I get the same order as shown in the screen after Javascript manipulation?

I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?
View 1 RepliesI have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.
I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:
Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)?
Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...
in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX
