I have MasterPage.master and 3 page that use this masterpage
1-home.aspx
2-product.aspx
3-information.aspx
in masterpage I defive 3 DIV
<div id="Home" runat="server"></div> <div id="Product" runat="server">
</div> <div id="Information" runat="server"></div>
I want in Home.aspx it change <div id="Home"> Background's image so I wrote below code in home.aspx behind code:
Home.Style["background-image"]=Page.ResolveUrl("~/Images/Extra/H.jpg"); but this error happen: the name Home doesn't exist in the current context
I think it happen because I define div in masterpage not in home.aspx so if I want do it what should I do?
I am using Javascript to alter the innerHTML attribute of a <td> and I need to get that info back in the form submittal. The <td> corrosponds to an <asp:TableCell> on the server-side, where the Text attribute is set to an initial value.
The user cannot enter the value in this particular field. Instead, its value is set by me (via client-side script) based on actions that the user performs. But this field is useless to me if I can't see its value on the server-side as well.
I'd like to avoid using a read-only textbox, because those are difficult to resize dynamically. Can an <asp:Label> be used as form data? Is there any way to achive this without letting the user manually enter the data? Or is there a simpler way to store a string as a variable somewhere and send it back as form-data?
I have the following html in my gridview in an item template :
<a
href="<%#Container.DataItem("ReciprocalURL")%>"
target="_blank"
title='<%#Container.DataItem("ReciprocalURL")%>'
id="recip">
So I thought that you could use id="name" and access this just like an ASP control such as <ASP:Checkbox
or <ASP:Label etc. My code continues to caugh and state object not set to an instance of an object when I uncheck my checkbox
Line 741: ElseIf Not Me.CheckBox1.Checked Then
Line 742: Dim row As GridViewRow = gvLink.SelectedRow
Line 743: Dim recip As HtmlAnchor = TryCast(row.FindControl("recip"), HtmlAnchor)
Line 744: Response.Write(recip)

I'm at my wits end on this one looked/Searched/Played/Experimented and I need your help if you can.This page is going to be primarily used on a mobile device using Win Mobile 5 Need to Accomplish:Prevent Postback(serverside) of Page using JavaScript (Postback's slow down the page on mobile device)
[code]...
I have an iframe in .aspx page , in which i open an html page(local) and I want to postback my .aspx page when user click on an img( that is in html page ) and get that image id on server side.
MyAspxPage -> Iframe -> HtmlPage -> img
I need to know if there is any server-side function/custom-code available to find out the HTML of the entire page which is causing the PostBack.
I don't want to do it using JavaScript/jQuery but instead do it at server side.
A JavaScript workaround that implements it can be found at this link. [URL]
Reason, Why I need it? I am writing some inline javascript in page which performs some vital actions and supposed not to be tampered by user(hacker). So, when a postback occurs, I would like to find out the HTML of entire page (at server) so that I can verify it (I have already generated the hash code for entire HTML while rendering the page to check it on consecutive postbacks) for non-tamering and then process further.
This is the reason why I need a way to find out the HTML of the page causing the PostBack.
Is there a way where I can actually view the name of a post back element? Below code goves me an alert but all it says is "object HTMLSelectElement". In my case it should be DropDownList3 based upon a "selectedindexchanged" event with autoppostback=true.
Code:
var pbControl = null;
pbControl = args.get_postBackElement();
alert(pbControl);
var ExecutingControl = "DropDownList3"
if (ExecutingControl == pbControl) {
alert("DropDownList3 - is the post back element");
This is kind of peculiar requirement..
I am using asp.net and jQuery together
I have a link button as follows
<asp:LinkButton ID="displayBtn" runat="server" OnClick="displayBtn_Click" Text="Display
Content"></asp:LinkButton>
I will hide this link button using
style="dipsly:none;"
and want to call the postback called by click of the asp link button using some other html element say a div.
<div id="invokeTest"> Click here </div>
I tried using
$('#invokeTest').click(function(){
$('#<%=displayBtn.ClientID%>').click();
});
Example Model:

Using the HTMLHelper's strongly typed methods on an instance of UserAccount my HTML elements are given IDs like:
id="PhoneNumber"
id="Credentials.Username"
This is awesome, it's great really. What I want is to be able to generate the same ID for a property in my controllers. My purpose is to link some additional error messages to the ID's. I can always just guess what it will be and enter it into the code, but I prefer to have a strongly typed way to do this. Does on exist?
Something like:
string usernameTextBoxID = MVC.GetHtmlIDForProperty<UserAccount>(u=>u.Credentials.Username);
my .aspx page a have this HTML element:
<table id="table7" runat="server"></table>
I want to use C# to put some rows inside ...
Of course, I chould do this:
table7.Rows.Add( ... );
But the problem is, I create the ID dynamically and I have multiple tables with IDs like "table1","table2", and so on....
string idFromDB = ... // retrieve the number from the database
string fullId = "table" + idFromDB;
HtmlTable tbl = .... get the element based on fullId .... ??????
tbl.Rows.Add( ... );
How do I reference the table element by the ID?
I am using ckeditor as my Rich Text Editor (RTE). This is an html element control and not an ASP control. I would like to use the RequiredFieldValidator (RFV) control to make this field required.
I cannot find any documentation stating that the RFV can be used like this. Can anybody tell me if this is possible?
Here's an example - notice that there is an html textarea element - how do I use RFV on this?

I have an ASP.NET web form where I have an hidden field, like this:
[code]....
On the method do_POST I have this:
[code]....
I just wrote this into my WebForms .aspx:
<span id="GenerateChartButton" runat="server"></span>
I went to the code-behind, and typed this:
this.GenerateChartButton
and it's not recognising that I added the span to the page. Is there something I need to do to make this happen? I have been working in MVC lately, so I haven't had to worry about the relationship between the page & code-behind in a while, but I can't remember any tricks that I had to perform to reference a HTML element in my code.
I would like to have this piece of code in my .aspx file:
<input class="ms-ButtonHeightWidth" type="button" name="BtnOK" id="Button2"
value="Close"
onclick="javascript:HandleOKButtonClick()"
accesskey="<%$Resources:wss,okbutton_accesskey%>" />
Unfortunately, ASP.net doesn't seem to like that:
An error occurred during the processing of /_layouts/MyPage/Info.aspx. Literal expressions like '<%$Resources:wss,okbutton_accesskey%>' are not allowed. Use <asp:Literal runat="server" Text="<%$Resources:wss,okbutton_accesskey%>" /> instead
That doesn't work in this situation as that would mean nesting the Literal between the quotes of the accesskey attribute, which causes a "The tag contains duplicate 'ID' attributes" error.
Is there a way to use a string from a resource without having to change the input to an asp:Button? I guess there has to be a way using <%=, but I don't know how I would address the resource itself?
I want to make a button that will create set of 4 textboxs everytime user click it and I need to save every sets of this to db.
how can i bind this textbox to the model or just forgot about strongly-type?
honestly,This is my third day on asp, .net , and MVC.
I'm trying to set a value for an HTML Element within my code-behind. I need to set a <div> elements "display" property to "inline". The way I have it coded is like this:
Code:
divContact.Style("display") = "inline"
Is this the right syntax? I only ask because it doesn't seem to work but I don't get a run-time error when the statement is executes. ???
I've been hired to clean up a website that was written by another company. One of the main issues they have is that the navigation menu doesn't always match the content. On closer look, they didn't use a navigation control or an accordion, but made their own user control out of HTML UL's and LI's (see below). Each section is supposed to expand when you click on it to offer sub menus. Any how, I am trying to find a way when the content pages load to force the menu to focus on the correct UL. Any thoughts on how to do this? By the way they wrote this stuff in 2.0, which I guess maybe why they didn't use the Accordion from the AJAX Toolkit.
HTML Code:
<div class="left-menu">
<div class="arrowlistmenu">
<h3 id="H3mymessage" class="menuheader expandable" onclick="RedirectBrowser(1)">
My Messages
</h3>
[Code] ....
Redirect Browser is defined on the master page:
HTML Code:
<script type="text/javascript">
function RedirectBrowser(ID) {
if (ID == 1)
window.location="MyMessageList.aspx?MessageFolderID=-1";
else if (ID == 2)
[Code] ....
Here is an example of how it is messed up. My Messages should be highlighted but My Profile is.
I have a View that has a select drop-down list and an edit button within a form. What I want to do is have the user select one of the options from the select element, click on the edit button, and get the value of the selected option in the Controller method.
I created my form with <% Html.BeginForm(): %>
and the Controller "Edit" method should be called.
I looked through several online examples, but each one focused on how to set values and the default selected value of the select element, rather than retrieving it from the code in the Controller method. I tried grabbing it from the Request.Form collection like:
string val = Request.Form["myDropDownList"].ToString();
and also:
string val = Request.Form["myDropDownList"];
Obviously I didn't do this correctly, because I get a null reference exception. Does anyone have the solution to this issue?
I was able to acces an HTML element from my c# code this way:
Page.Request.Form["Name"].ToString(), where name was an html element:
<input id="Name" style="z-index: 102;" type="file">
Now that I put this html inside a Tab containe (subpanel) the Page.Request.Form["Name"].ToString() fail, actually while I was debugging I could not find this element inside Page.Request.Form.
maybe there is another way of accessing the Html element from my c# code?
I must to read table in html file. I'm try to read html table to data set and xml but it dosen't work. Anyone have any solution to read table or entity control in html file.
View 4 RepliesI want to replace a form element with a div and keep the inner html of the form inside the inserted div element. i tried jquery it gives me unkown html element as selection result,
below is the target form and inner html:
<form name="Contents2_frmLogin" action="/SiteManagement/SiteWizard.aspx" method="post"><table border="0"><tr><td></td></tr></table>
</form>
stackoverflow not allow html code. it is just a form element with a table inside and some input elements
In general, If I have a choice when developing a web site to use html elements or asp.net controls which one is better to use if my website is interactive with server side operations such as accessing database. Is it more secure to use asp.net controls or does not matter.
On other words, is it more secure to use asp.net controls instead of html element to deliver data or receive data from/to server side or no differences?
I'm creating composite control, which has two other components that rely on each other.
In component A (image), I access component's B (input) UniqueID which equals
MyTextBox1$BoldTextBox
I use it in onclick JavaScript code...
But in rendered HTML input element has following id
MyTextBox1_BoldTextBox
So my javascript code , generated inside composite control has something like this:
onclick=$('#MyTextBox1$BoldTextBox').....
instead of:
onclick=$('#MyTextBox1_BoldTextBox').....
Is it any theme or css framework can apply to ASP.NET?
I work with ASP.NET webform, everybody known web controls generate pure html to work.
I already work with jQuery and Ajax Controll Tookit,but it not much to make a modern UI design.
I have found some commercial library like ComponentArt,DevExpress etc, but is it any free or opensource i can use?
