I pick up on the nerddinners examples, following Professional.ASP.NET.MVC wrox book. but now i'm doing some modifications for my own account. On traditionl ASP.net it was possible to interact with html elements (divs, textbox, etc... )On MVC 2 is that possible or any interaction with html must be done with jquery and how? Because i'm trying to manipulate an html element on my Controller page(DinnerController.ASPX and i had no reference to html div, as i initially supose.

View 2 RepliesI want to know how the server will process my page that contain:
1- ASP.NET markup mixed with HTML elements.
2- Code behinde.
Will it read the ASP.NET markup line by line and even HTML elements? And then reads the code behind? or what exactly?
Setting value in html control in code behind without making server control
<input type="text" name="txt" />
<%--Pleas note I don't want put runat=server here to get the control in code behind--%>

I am trying to write a linq query that will retrieve all the ID's from any asp tag. Also, the query needs to group everything together alphabetically. So for the example above, the linq query should return "lbl1", followed by "lbl2", followed by "txt1", and finally "txt2". Notice it did not grab the "bodyID" because it was not part of an ASP.NET tag. Is there an easy way to do this? I am using C#, by the way.
I recently designed my own user control.
My control consists of an ASP:Tree control and a plain HTML text input with copious Javascript, jQuery, and .net code to bring them to life together.
I have two issues.
1) I can only have one instance of this control on a page at a time. The text input is named txtUserControl, so putting a second instance on the page causes a name collision. I have the same issue with the ASP:Tree.
2) If I put my user control inside an ASP:UpdatePanel, it does not work at all. I get errors all over the page when I try to refresh it. Incidently, I have this same issue with a user control created by one of my co-workers.
I have some ideas for controls that I would like to be able to use again and again in my projects. I would like them to be rock-solid.
I have some simple code in an aspx page
<object width="550" height="400">
<param name="movie" value='XXXX' />
<embed src='XXXX' width="350" height="370"></embed>
</object>
I want to be able to dynamically set the value of XXXX.
Lets assume that I have retrieved page html using HttpWebRequest & StreamReader. Now I would like to cut one div from the loaded html and put it in literal on my asp.net page. I know that that div has css class content. How can I do it?
View 2 Repliesrecently i used literals inside HTML elements like so:
Code:
<div <asp:Literal ID="ltlpbEmpty" runat="server"></asp:Literal> align="left" <asp:Literal ID="ltlToolTip" runat="server"></asp:Literal>>
<div <asp:Literal ID="ltlPBFull" runat="server"></asp:Literal> <asp:Literal ID="ltlBarWidth" runat="server"></asp:Literal> align="left">
</div>
in this case both of this divs are part user control progress bar i'm making, from not related reason i couldn't use ASP.NET elements and had to go back to the traditional HTML elements.so to be able to give those elements dynamic attributes such as tooltip, id, class i had to add literals inside those elemtns..
I have been experiencing some very strange behavior using html buttons with the onserverclick attribute. What I am trying to do is use jQuery to designate the default button on the page. By default button I mean the button that is "clicked" when a user hits enter. In testing, I would hit enter while in an input field and sometimes the intended "default" button was clicked and the server side method defined in the corresponding onserverclick attribute was hit. Other times a post back was made without hitting the server method. In order to isolate the issue I created a minimal test case and found some very interesting results.
Client side:
[Code] ....
Server side:
public partial class admin_spikes_ButtonSubmitTest : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e) {
} protected void ServerMethod1(object sender, EventArgs e) {
_response.Text = "server method1 was hit";
} protected void ServerMethod2(object sender, EventArgs e) {
_response.Text = "server method2 was hit"; } }
What I found was that everything worked as expected with this code except when I removed one of the input elements. In Firefox 3.6 and IE 8 when only one input exists on the page, hitting enter does not trigger the onserverclick, it makes a post back without even being jQuery "clicked" or actually "clicked". You can test this by starting with two inputs and clicking "test2". This will output "server method2 was hit". Then just hit enter and the output will be "server method1 was hit. Now take away an input and run the same test. Click "test2" see the results, then hit enter and you will see that nothing will change because the "test1" method was never hit. Chrome worked as expected
I am having doubt in whether to use string or string builder to append html elements like "div" and others in my page in mvc. Is there any other approach for this thing.

my application runs on the client side. I have to access a display on the asp page via javascript. I have the following code working properly:
ClientSript.RegisterStartupScript(this.GetType(), "allMessages", "<script>document.forms[0].tbDisplay.value='Messages'; </script>");
tbDisplay is a "text box" asp:textbox control. I need to replace de 'Messages' for avariable. so instead of printing "Messages" all the time, I can change the information on the variable prior to display the message. how to change 'Messages' to a variable.
I want to call the corresponding html inside a Panel in code behind. How can I do that?
I have this
<asp:Panel ID="MyPanel" runat="server">

I want to get the HTML equivalent of MyPanel and all of its contents in my code behind say in PageLoad or some methods.
I have bunch of HTML code I am using to make rounded edge boxes on my controls. Is there a way to take this code and turn it into some kind of control or something so I do not have to keep pasting 10 lines of HTML code around everything I do?
<div id="BottomBody">
<div class="box1024" >
<div class="content1024">[code]....
One additional thing to note, the number HTML tags used inside the inner most DIV will change depending on where I use it in my site. So in some cases I will only have 1 tag and 1 tag but in other cases I could have 1 tag, 1 tag, 3 tags, and a HTML table. How can I make that work?

I'm not sure if the topic describes my problem very well but I am creating some HTML elements (textboxes) on the fly with jQuery and I never know how many I will create (it loops through a database). I then want to get all the elements in the code behind and perform some actions (insert them into another database).
I know I can use
string n = String.Format("{0}", Request.Form["hiddenField0"]).ToString();
To get the first textbox but what if Idon't know how many textboxes I have created and want them all? Their name starts with hiddenField plus an incrementing number.
Is there a way to loop through all elements that has a name that starts with a certain string?
Basically I want to load a HTML document and using controls such as multiple check boxes which will be programmed to hide, delete or show HTML elements with certain ID's. So I am thinking I would have to set an inline CSS property for visibility to: false on the ones I want to hide or delete them altogether when necessary.
I need this so I don't have to edit my Ebay HTML templates in dreamweaver all the time, where I usually have to scroll around messy code and manually delete or add tags and their respective content. Whereas I just want to create one master template in dreamweaver which has all the variations that my products have, since they are all of the same genre with slight changes here and there and I just need to enable and disable the visibility of these variants as required and copy + paste the final html.
I haven's used Windows Forms before, but tried doing this in WebForms which I do know a bit. I am able to get the result that I want by wrapping any HTML elements in a <asp:PlaceHolder></asp:PlaceHolder> and just setting that place holders visibility to false after the associated checkbox is checked and a postback occurs, finally I add a checkbox/button control that removes all the checkboxes, including itself etc for final html. But this method seems just like too much pain in the ass as I have to add the placeholder tags around everything that I need control over as ordinary html elements do not run at server, also webforms injects a bunch of Javascript and ViewState data so I don't have clean HTML which I can just copy after viewing the page source.
Any tips/code that you can suggest to achieve the desired effect with the least changes required to existing HTML documents? Ideally I would want to load the HTML document in, have a live design preview of it and underneath have a bunch of well labelled checkboxes programmed to hide, delete or show elements with certain ID's.
I have created a Web User Control (e.g, uc.ascx) which has a few HTML checkboxes in it (using Input Checkbox).
As uc.ascx is dynamically created in my webform page (e.g. page1.aspx), I discovered that the HTML checkboxes did not persist their "Checked" status. how I can make these HTML checkboxes persist?
