Jan 4, 2011

May return controller:

When I actually click a button, the value assigned to strButtonClicked is correct.Example: Click "Login" --> strButtonClicked = "Login"When I hit the "Enter" key, I get a different value.Example: Hit enter --> strButtonClicked = "I forgot my User Name and/or Password"Below is a View that works correctly:

i have a dummy javascript that can trap for enter key on the client side
Code:
[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.

I have a string value from a user input box. I have to figure out if last char is a enter key (line feed).
Thats the code. Here I am checking if last char has a whitespace. Now I also have to check if last char is enter key (carriage return or line feed). How can i do this?
var txt = $get("<%= txtUserText.ClientID %>");
if (txt.value.substring(txt.value.length -1) !== ' ' || <checkifLastCharIsEnterKey>)
//my code to take action
**I don't think i need a keypress or keyup event because this above piece of code is not invoked at the time of user input.

I have a page with multiple textboxes and each has a button associated with it. This works as a search 'hub', I suppose, where the user can search by ID, name etc. When entering a search term for e.g. name however, pressing enter 'clicks' the very first button on the page (ID search), causing an error if the associated textbox is empty (which it would be if someone meant to search by name). I have attempted to rectify this using JQuery, and have written the following:
$('input:text').click(function (e) {
e.preventDefault();
$(this).next('input:button').focus();
});
I'm simply using the click event so that I can monitor where focus is redirected, but eventually I would use .keypress. However, nothing happens upon clicking a textbox and I can't see for the life of me what is wrong with the JQuery. To elaborate on the problem, the .NET code used looks similar to the following throughout the page.
<tr>
<td style="width:100">Company ID</td>
<td style="margin-left:3px;">
<asp:TextBox ID="...TextBox" runat="server" Width="230px"></asp:TextBox>
</td>
<td>
<asp:Button CssClass="Button" ID="...NameSearch" Text="Search" runat="server" /></td></tr>
This is generating this (view source):
<td><input name="...TextBox" id="...TextBox" style="width: 230px;" type="text"/></td>
<td><input name="...NameSearch" class="Button" id="...NameSearch" onclick="javascript:__doPostBack('...NameSearch','')" type="button" value="Search"/></td>

I have a textBox where a I enter some text. After this is done I will press "Enter" on the keyboard to call the control Button1 that I have on the same form.
Assume that I have: textBox1 and Button1 on my form. In somehow I will need to identify that "Enter" is pressed in the textBox1 ?

I have a need to monitor the state of the Shift key, whether it is up or down. Its purpose is to notify the user that while the shift key is held down, the drag and drop operation they are about to perform is going to COPY the node(s), and not move them.
I have it working perfectly with the code below, however, if I hold the Shift key and perform the drag and drop, the hook no longer exists; the screen no longer responds to the key press and remains in the "pressed" state.
<form id="form1" runat="server">
<div>
<table>
<tr>
<td valign="top"><ASP:Literal id="treeLeft" EnableViewState="false" runat="server" /></td>

how to execute the code behind function using JavaScript keypress ?
The reason is that the keypress that I'm referring to will be used in searching record so I want that every keypress a result will be shown in the gridview immediately.

Users don't like the fact that the Enter key submits the page. So I am tasked with preventing the submission and changing the Enter key to a Tab to the next field. I have tried many javascript snippets found on the net but none have worked so far. The only one that has even come close to having an effect was e.preventDefault() of the jQuery API, which stops the submit, but nothing I have tried emulates the tab behavior.
e.returnValue = false;
e.cancel = true;
Page still submits with the above in the keydown event handler. Same effect with return false in the keydown event handler. The handler is firing, tested by putting a breakpoint in it with firebug. This needs to work with both IE and Firefox. Don't say "don't do this".
1) I'm already convinced that I shouldn't do it, but it's not a choice that is mine, so the discussion is mute.
2) It would be an answer to the question "Should I do this?", which is not the question that I am asking.

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.
