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">
// other asp.net controls and html stuffs here.
</asp:Panel>
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'm trying to create a .net charting control completely in the code behind and insert that chart at a specific location on the web page.
Here is my html page:
[Code]....
I want to render the charting control inside the div with id="chart"
Is there a way (without overriding Render) to get the Rendered HTML output of a UserControl? What if the UserControl as a control tree with other controls in it?
View 1 RepliesI am using ASP.NET. I have an html table. One of the table cells (td) has two buttons. Just recently, when it is being rendered it is wrapping the buttons. Can anyone tell me why this is happening?
View 2 RepliesRecently we copied an ASP.NET WebForms solution. In this solution we are using some ASP:ListBoxes where the Rows property is set to more than 1.
This renders following HTML..
<select size="8" name="ctl00$MainContainer$lbType" multiple="multiple"
onchange="javascript:setTimeout('__doPostBack('ctl00$MainContainer$lbType','')', 0)" id="ctl00_MainContainer_lbType">
<option value="--">-- - --</option>
<option value="BR00">BR00</option>
<option value="BR01">BR01</option>
<option value="...">...</option>
</select>
Looks fine to me. But the strange thing is that in the copied solution the browser doesn't render what it should be rendering. The size property seems to be ignored. It just gets rendered as if the size was set to one.
This applies to all listboxes in the solution. I compared the masterpages and web.configs and there are no differences. This issue also applies to all browsers. I used IE8 Developer tools to compare the documentmodes and they are the same for both solutions.
I try to send an email with the html generated from an aspx file. But having this problem that only capture the aspx text not the html rendered by aspx. how can i do it , must use htmltextwriter? This is the code sample

I have a rendered html page which i am exporting to MS-word and downloading on a button click.
The code snippet in the button click.
Me.EnableViewState = False
Response.ContentType = "application/vnd.ms-word"
Response.AddHeader("Content-Disposition", "attachments;filename=XXXXXXX.doc")
Response.Buffer = True
Response.BufferOutput = True
The functionality works perfectly well in FireFox & IE when i checked in system testing envirenment(locally).However when in was moved on to hosting server(production environment) the functionality is not working in IE , however it is working perfectly in FireFox.
I am not sure on where to check the exact issue for.Will it be any caching related problem?.
In IE it is just not opening the download window which we will obtain when the rendered html content type is changed and response stream flushed.No exception is thrown.
I received the following response header :
HTTP/1.0 200 OK
Cache-Control: private
Content-Length: 15189
Content-Type: application/vnd.ms-word;

I am working with .net c#. Is there a way to see the rendered html code under the updatepanel?
more info:
I dynamically generate UI controls and place them in a asp:Panel control I have under updatePanel. My page is initially almost empty, and I add about 50 new controls upon button click. However, I cannot see the html code generated in the page source. as in, I can see my textfield on the screen but I cannot see the corresponding code in the html source on my browser.
I developed a basic web page in MVC 2 for learning the framework, and I am stuck in this situation:
I have 3 classes: Client - Product - New. And for all need to display a modal popup to create/edit action. For display the modal i used JQuery and jqModal plug-in.
I created the controllers for all objects, the views for Index action, and Delete action. For the Create/Edit Action I created a partial view named ModalBox. Inside this partial view, I have an Ajax.BeginForm, and it calls another partial, that represent the form of the objects.
This works very fine, ... for the project object! in FireFox 3.6, for others object's the form tag is missing...
I have some javascript to iterate the divs in my web page. There is also a ReportViewer control. If I look at the HTML in FireBug in FireFox I can drill down to a div with an id of "oReportDiv". However, my javascript does not pick this up and if I view Source I cannot find it there either. It is the same story in Internet Explorer - I can find the div in the developer tools but not in the source.
The div is buried in nested iFrames and Framesets and all sorts of nasty looking stuff.
Ive tried [OutputCache] for a view that is rendered from Html.RenderPartial, but it doesn't work! It works perfectly for 'normal' views.
How do I cache output for partial view?
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--%>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
Code behind
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
//If I want to initlize some value in input, how can I set here
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Request["txt"] // Here I am getting the value of input
}
I have a gridview control inside an updatepanel. When I run the app and look at the source code generated, there is no source code about gridview. So, I can't aproach to the elements inside the gridview.
My question is, where is rendered code of gridview and how can I approach controls inside it?
I have a simple user control which is nothing but a simple input field with runat="server":
<input id="mySimpleTextBox" type="text" runat="server"/>
My observation so far in the output rendered by a datalist (when I use this user control inside it) is that the value for the name attribute is the same.I want to use this control inside a datalist/repeater such that I'd want a unique value for the input element's name attribute when the datalist/repeater renders. How is this done?
EDIT: My bad obversation. Actually the names are unique. However, when I try to post the page to another web page which outputs the key & value of all the items in Request.Form I don't see the input elements...
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.
How can I control on HTML elements by using C# code in asp.net pages.
For example:
I want to change the content of span tag or td tag when load page... that's mean write code c# in Default.aspx.cs for example to change Span content
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 had a website with a few asp.net controls with id like:
btnSave and tbAmount
I renamed one of my controls and when I tried to use it in the code behind I get the following error.
Error 5 Name 'tbAmount' is not declared.
I was messing around trying to add new controlls rather than rename, but nothing seems to work.
And now, none of my controlls that were added to the page are recognized in the code behind. They all have the error:
Error 5 Name 'tbAmount' is not declared.
Or
Error 3 Name 'hfNoteId' is either not declared or not in the current
scope. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 33 71 NoteTender
Even my button click event handler gives me the following error:
Error 2 Handles clause requires a WithEvents variable defined in the containing type or one of its base types. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 27 91 NoteTender
I have verified that my inherits is using the correct namespace and class name.
I have to access my html control and get its value from my server-side code. Is there anybody who could suggest how I could do it?
My html control is very simple: <input type=text>
But the thing is: I can't make it <input type=text runat=server> cause in this case my jquery functionality (datepicker) does not work.
Here is the contents of my test.ascx file:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="test.ascx.cs" Inherits="UserControls_test" %>
<p id="XXX">aaa</p>
and here is the contents of my test.ascx.cs file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class UserControls_test : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
this.XXX.InnerHtml = "BBB";
}
}
I get an error when I refer to the id, "XXX" (underlined above) in code behind which reads: 'UserControls_test' does not contain a definition for 'XXX' and no extension method 'XXX' accepting a first argument of type 'UserControls_test' could be found (are you missing a using directive or an assembly reference?)
I have tried XXX.InnerHtml and I have tried this.XXX.InnerHtml and get same problem.
How do I successfully refer to ID'ed HTML elements in code behind?
I am struggling with something that I guess should be standard practice really. I have a number of user controls that use some JQuery plugins. I do not really want to link to the extra CSS and JS files from my main masterpage as this would cause extra load to the user the first time they hit the site, (admittedly it would only be the once), so I was just putting them links into the top of the user control. Then I looked at my source HTML, not nice! Even worse for controls that repeat multiple times on a page.
So I was thinking is there a way of injecting them into the Head of the page when they are needed from the User Control. For that matter is there a way of doing it to the footer for JS stuff?
I have to add a dropdown control in the web part. I am rendering the part using HTML Strings as follows...
StringBuilder sb = new StringBuilder();
sb.Append(div id="content); There are quotes in the string
sb.Append(div class=""hb"">");
*sb.Append(div class=""someclass"">");*
sb.Append(h2 id=""contentpage_title"">Title");
**sb.Append(div class=""ctn_conferences"">");**
writer.Write(sb.ToString());*
I have to add a loaded dropdown control...so I declared..
protected DropDownList ddMyDropDown = new DropDownList();
Then added the control in the middle of the render where I wanted as follows...
ddMyDropDown.RenderControl(writer);
Everything is fine....except... the post back does not work. My event handlers are not getting executed.
When I add the control ...like Controls.Add(Control) then it adds at the bottom of the part. That is not what I want.
So how do I get the post back to work?
My Tab Container works fine on my development machine. But it doesn't show up my production machine. On closer inspection, the Production machine renders it as hidden. Any thoughts on why this would happen?
Mark up:
<asp:TabContainer ID="tcAuditMain" runat="server"
Visible="true" ActiveTabIndex="10" EnableViewState="true"
CssClass="NewsTab" Width="100%">
Rendered:
<div id="ctl00_ContentPlaceHolder1_tcAuditMain" class="NewsTab" style="width:100%;visibility:hidden;">
I'm currently stuck settings border in a html table. (I use inline stiles for a better rendering in e-mail-clients) I have this piece of code:
[code]....
That will be rendered as this:
I want the table to be rendered like Excel would render a table with inner and outer border.
