Two separate questions, but sufficiently intertwined that I'm going to try the two together....
Firstly - User Controls and Behaviours
I have a User Control which contains a few visual controls. I am attaching some behaviours by using GetScriptDescriptors and am passing some JavaScript to the browser using GetScriptReferences. That is all rock solid and working well. However, when developing, I did discover that I couldn't attach the ehaviours to the User Control itself - not surprising as rendering a User Control does not create a DOM element which represents the actual control. So, I have attached my behaviours to a "random" TextBox within the User Control.
So - first question, is there a better way to do that? For example, should I always be rendering a SPAN as an element to surround the control? Not sure what that would do to the robustness of the rendering. What is the right way to attach a behaviour to a User Control.
Secondly - Accessing those same Behaviours later
Assume I have placed a User Control on the page. That User Control exposes a Property (actually a Javascript Function of course) which does "something" to the control - for the sake of example we'll say that the function is set_Border(colour). I then have a behaviour on the same page (actually an Extender on a different control) which needs to call the function. I have a reference to the User Control in my script, so I have tried TheControlReference.set_Border('red') and find that my control doesn't support the set_Border method.
I guess this is probably because the behaviours are not attached to the User Control itself, but to a GUI element within it. Hence, I suspect that the answer to the second question lies within the answer to the first.
I'm having trouble managing how to call upon databind from clicking on a row over an already populated repeater that will populate data regarding the row clicked TO another repeater on the same page.
I've succeeded doing that with postback, calling a jquery click event of that row, taking the data of the specific row and passing it onto a "Querystring" and after postpack, it will be pushed into a Session which the ObjectDataSource of the secondary repeater will recognize and populate the data tables accordingly.
The problem is, I must do it without a postback or in other words purely on client side.
I have a JQuery (using JQuery 1.4.2) problem that exhibits only in IE8 in standards mode, on one specific DOM element but not on other nearly identical dom ellements. The best example of why it makes no sense is below:
$('span.error:visible')[0].style.display
The above piece of code returns "none" which unless i am having some sort of brain aneurism is impossible without there being a bug in either JQuery or IE8. This only occurs in IE8 in standards mode, not in any other browser or on IE8 compatiblity mode. The span that it finds is actually an ASP.net validation control so i only have a limited amount if control over what it renders to the browser. When i inspect the DOM using IE8 developer toolbar and copy the HTML from the DOM it gives me the below:
<SPAN style="DISPLAY: none; COLOR: red"
id=ctl00_cphContentBody_mnMainMiddleNames_ebvMiddleName1 class=error
controltovalidate="ctl00_cphContentBody_mnMainMiddleNames_txtMiddleName0"
errormessage="JQuery should not find this" display="Dynamic" validationGroup="MiddleNames"
isvalid="true" validationexpression="[A-Za-z][A-Za-z '-]*[A-Za-z]*">JQuery should not
find this</SPAN>
If i just do a view source and copy and paste it i get the below:
<span id="ctl00_cphContentBody_mnMainMiddleNames_ebvMiddleName1" class="error"
style="color:Red;display:none;">JQuery should not find this</span>
If i create a simple HTML file containing just either of the above pices of HTML then $('span.error:visible') does not find the spans and i am unable to post code to be able to reproduce this problem. But in the actual asp.net page if i run $('span.error:visible')[0].style.display it returns "none" and if i run $('span.error:visible').text() it returns "JQuery should not
find this".
tl;dr How can $('span.error:visible')[0].style.display return "none".
Edit to answer Nicks comment.
$('span.error:visible')[0].offsetWidth returns 3
$('span.error:visible')[0].offsetHeight returns 22
Which is puzzling, i found the below on the Jquery site.
In jQuery 1.3.2 an element is visible
if its browser-reported offsetWidth or
offsetHeight is greater than 0.
THe element isn't visible, but acording to the above JQuery thinks it is. What does this change mean? It means that if your element's CSS display is "none", or any of its parent/ancestor element's display is "none", or if the element's width is 0 and the element's height is 0 then an element will be reported as hidden. So is the above just wrong. Display is "none" but offsetWidth and offsetHeight are not zero
Suppose i am having 25 character length string and I want to bind only first 15 character of that string into the label control.
<a href="[URL]" >"<span class="name" style="text-align: left; font-family: Arial; color: #0094DA; font-size: 14pt">
<%#Eval("Name").ToString().Length >= 30 ? Eval("Name").ToString().Substring(0, 30) : Eval("Name").ToString()%></span></a>
There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8.Here is the test code:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script>[code].....
This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem.
I know how to use a simple If statement wrapped in the <%# tags to hide something, but I don't know how to do it in a repeater when I need to access Container.DataItem, as in I need the dataItem currently being 'repeated'
eg
if (CurrentValidationMessage.Link != "")
{
show a hyperlink
}
Markup:
<asp:Repeater ID="repValidationResults" runat="server">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<a href='<%# ((MttImportValidationMessage)Container.DataItem).EditLink %>'> Link to erroneous Milestone </a>
<%# ((MttImportValidationMessage)Container.DataItem).Message %>
<br />
</ItemTemplate>
</asp:Repeater>
I have an aspx form containing many individual controls like and one repeater control. The repeater control items are basically having dropdowns, textboxes etc. next to each other. My problem is I can set the tab index of each individual element easily but I don't know how to set the tab index of the first element in of the first repeater item. That is why first I need to click the item and then the Tab index inside the repeater control works fine. Do you know how can I fix this? Should I handle this on the server side? or jQuery etc?

How do I capture other events in an asp.net textbox on a webpage in more of a way in which a windows app does? For example, if I want to handle when someone just presses a key (keydown) on a textbox in a webpage?
The functionality that we want to create breaks down like this:
We want to create a "smart" search box at the top of our page. When the user starts typing, a little panel or some element should become visible and it will have some check boxes on it. They can search for one or many different types of searches: First Name, Last Name, Business Name, ZIP, Customer Number, and Contact Info. As they begin typing their search, we need it to execute some code that attempts to figure out exactly what they are searching. So if it can tell they are typing in alphabetic characters and not numbers, then we know to NOT check the Customer Number box, but we will want to check the First Name, Last Name, and Business Name boxes. If they start typing a number, we know that we can check the Customer Number box and leave the First Name and Last Name, etc boxes unchecked. If they type a number that is 5 digits, then we know to check the ZIP and Customer Numbers both. Any other length number characters and the ZIP will be unchecked. And any other rules like these that we might want to implement in the future. The idea here is we will almost always be able to tell what someone is searching, but the user can always check any box that they want to search for if they so choose. For example, if a business is named "123 Plumbing Company" and they just want to search the Business Name field for a number, they can over ride it and do that. Otherwise, they just can blindly type their search and hit enter and the program will usually know what kind of search they are trying to do.
I come from a strong windows app development background and have just recently tried to do some web development professionally. A quick few sentences on what philosophy I am missing out on as far as a more robust and "Windows App-like" webpage would be appreciated if anyone wants to coach me on that area and point me in the right direction!
Also, in my example we are using master pages. So if you can imagine a typical master page that has a logo top left and a search box and button top right, then you can picture what we have. Its simple looking. But with the content page being a separate aspx page, we are having trouble referencing it after a search is performed anyway. So what I mean by all this is The masterpage.master has a search textbox. They type something, hit enter. We then want a gridview that is on our default.aspx page to update with the results of the event that was fired from the masterpage.master.
My windows app background tells me to just point to it like I would from two different forms. Like if I had a form1 with a search box on it and I wanted it to show up the results on form2, I would just say Form2.Show: Form2.GridView = whatever.
Of course, with my confusion of what the scope of these asp.net pages is, I am having a difficult time just visualizing everything and how they are inter-related.
So I guess to recap here:
1) How do I tap into more events with textboxes or any other asp.net control. Is the answer AJAX? If so, can you elaborate just a little bit?
2) How would I use the keypress or keydown type of event to make a panel or some kind of content holder to become visible when the textbox gets focus from the cursor and go back to being invisible if it loses focus.
3) What about the scope in which asp.net pages behave?
i have a panel(visible false) in a page and a user control. i have a button in a user control when i click that user control button then i need to make the panel visible in the page... (panel which is not in the user control)...
