I have a Master Page as well as a standard Web Form aspx file. What if I wanted to dynamically modify the complete HTML markup in an aspx file (perhaps based on a conditional statement - perhaps in a specific content place holder), how would I go about doing this? Sorry I'm coming from a PHP background so this is why I'm asking such a simple question.
View 1 RepliesSince ASP.NET response filtering and post-cache substitution are not compatible, I need an alternative way of filtering output. Reference: http://support.microsoft.com/kb/2014472Is there any way to change the markup without using response filter?
View 1 RepliesI'm trying to add some basic HTML markup to my code-behind, just a H1 and a few breaks separating strings in the message.Body, but can't seem to get it going without errors.

Probably a straightforward thing, or not intended usage at all,
I have a field in my SQL database that contains HTML markup from the HTMLEditor control in the AjaxControlToolkit. When I use the Report Viewer and SQL Reporting Services to display this field in a report, the field is displayed using the tags. I would either like to hide the tags completely or render them so that they format the text appropriately, rather than the tags be displayed as a load of <p>, <br>, <strong> tags etc. I've searched around and tried out a few different articles but haven't yet had any success.

is it a right to do something like this?
i've to display a messagge in my homepage (default.aspx) different for each "installation" of my web app. i would like to avoid to make a call to database to show this message.. so i've thougth to use web.config to store something like this
<add key="WelcomeString" value="lorem ipsus <b>doloret sit amen</b>" />
But i've noticed i can't use html markup into web.config Is there a better approach ? Or is there a way to insert html markup into web.config ?
I'm a new comer to the asp.net world. I hear a lot about asp.net mvc and it's advantage over webforms about the ability to customize the markup and css. I also heard that asp.net is much easier to learn than asp.net mvc so I decided to go for asp.net and webforms. My question is: what's the level of customization a web developer/designer can get with webforms concerning the markup and css?

I have an ASP.NET site which uses a 3rd party activeX control. I have to pass a few parameters to the OBJECT tag in the HTML page. If i hardcode these parameters into the HTML everything works.
I would like to place the parameters in my web.config with app settings "key/value" pairs.
My problem is i cannot read the app key setting in the HTML markup to succesfully pass them in as parameters. I can read them fine from server side code behind.
What's the correct way to read these settings in the client side HTML markup ?
I have an asp.net page i do authentication and authorization of a user and user can make several ajax requests from this page. What i want to ensure is that the request only from this page so i will store some data(or token)(possibly a function of userID + user IP address + current time) encrypted in the page aswell as in the session so the requests that come with this token will only get served.
View 1 RepliesHi,
Everytime I view the source of ASP.NET website I found alot alot of HTML markup generated. I even tried Visual web Developer and design a simple page and then do the same thing with PHP and I found ASP.NET generates more HTML!
Now, how can ASP.NET be faster if it is generating HTML in this way!
below is a sample ow what i'm tring to do
[Code]....
what it should output is my enable image with the text on the right saying 'enable' if i only have Text='<img src="app_images/enable.png" />' i have the image, just a question of how to add the resource entry at the end of it...
Is it possible to access the html markup of programmatically created controls, and if so, how?
In c# you can write things like:
[code]...
I need some people to edit the ressource file without seeing html markup.
How can I do that .. ? I tried RESX edition but it doesn't hide the markup.
What is best practice for saving and displaying rich text?
Example: I want to store an article with links, different font styles and so on. What format should it be saved in?
How are people saving their "content".
I have the following call in my app:
...
var message = "<label style='font-weight: bold; font-size: 14px; color: Gray;'>" + currentPlayerName + "</label>: ";
$.ajax({
url: "/Game/SendMessage",
type: "POST",
[Code]....
When I call this function it always drops an error. I think there is a problem with the data that I want to send back to the server.
I'm thinking there has to be an efficient and OO way to do this.
I have several textboxes on a data entry page. When I need to make a new entry, I have to clear the text field before making new entries and this has to be done for quite a number of textboxes and across several pages.
Is there a way to use the FindControl method to locate all textboxes on a page and clear their textfields probably using a loop of some sorts?
I want to access the raw HTML code that my ASP.NET System.Web.UI.Page is about to render.
How can i do that? Is there a property or method like System.Web.UI.Page.HTML or something like that.
I know I could loop through the Controls List of the page and get access to all the Literal Controls etc, but I was wondering if there's a direct property or method that can return me the raw html, which I can modify just before rendering the page.
I'm doing some research on security and sitemaps in ASP.net and am unfortunately running short on time. I have not worked too much with ASP.net security so I'm not completely sure if I'm heading in the right direction.
Here is my problem:
I have a public website (i.e. on the internet) that will allow any user to sign up to. The website will be developed using ASP.net webforms. These users may create other users and assign these users different roles.
Different roles have different restrictions and the menu is displayed appropriately. For example, a user acting as an administrator can see all menu options. Whereas a limited user will only see some of these menu items.
There needs to be the ability for users on our end to modify what pages certain roles can access. For example, if Role1 can do task X, we would like to be able at some point modify Role1 to no longer do task X. This would be done using an application built in-house.
User types (roles) are to be saved in the database. User permissions (what pages each type can have access to) are also to be saved saved in the database.
Here is something I am thinking of doing:
Implement the authorization and authentication set up built in to ASP.net using the web.config fileUse Sitemaps to dynamically create menus/breadcrumbs from the database
I believe it is possible to do the second one using custom providers (please correct me if I'm wrong). But I am not entirely sure if it's possible to configure the web.config file dynamically.
I suppose this is really more of a yes/no answer but I would just like to make sure I'm not going in the wrong direction. I will be using VS2008 and .net 3.5 framework.
Is there some way to intercept the HTML output stream in asp.net and make modifications? Eg using httpmodules or something? I know this is possible using java servlets and assume there must be an elegant way to do this with asp.net.
My purpose is to combine the many javascript files into one composite script which has been minified/packed, to make the page load faster.Eg, if my page normally outputs the following in the page head:
<script type="text/javascript" src="/scripts/blah.js"></script>
<script type="text/javascript" src="/scripts/yada.js"></script>
I want to replace that with the following:
<script type="text/javascript" src="/scripts/all.js"></script>
(also i realise i'll have to create all.js somehow).
What I'm trying to do is take an instance of a control, and figure out what the markup would look like based on the property values set in the code behind. We've built a web-based web form designer. At the end of the design process we save the markup. For simple controls with supported types, generating the markup was easy. For complex controls with nested properties or unsupported types, we're faced with creating a custom markup generator for each custom control. I was hoping to find info out there that would jump start this development effort.
In simple terms, I have this:
Dim Ctl as Control = CType(Asm.CreateInstance("MyNameSpace.MyControl"), Control)
Ctl.Name = "Name of my control"
And I want to end up with this:
<cc1:MyControl ID="MyControl1" runat="server" Name="Name of my control" />
I 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?
I am trying to integrate URL.... I am selecting urls of 3 images from database and and displaying those 3 images from a particular album. Now the problem is that what if the user has multiple user? It should be able to generate as many Jquery albums on the page as there are in the database associated with that user.
<div class="image_stack" style="margin-left:300px" runat="server" >
<img id="photo1" class="stackphotos" runat="server" clientidmode="static" >
<img id="photo2" class="stackphotos" runat="server" clientidmode="static">
<img id="photo3" class="stackphotos" runat="server" clientidmode="static" >
</div>

Let's say that I have the following HTML for a text box on an ASP.NET page:
<div class="myClass">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>
It is easy enough to add a required field validator to this page like this.
<asp:RequiredFieldValidator ID="valMyTextBox" runat="server" ControlToValidate="txtMyTextBox" ErrorMessage="My Text Box is required."></asp:RequiredFieldValidator>
But I need to modify the HTML slightly if this text box fails validation. I need to add a CSS class to the DIV. So if the user leaves this field blank I need the HTML to look like this:
<div class="myClass error">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>
Is this possible? I can't figure out if there is a way to write code behind that only fires if this particular validator control fails validation or something. I know I can write code that runs when the entire page is not valid. But I just want this code to run when this validator returns invalid. Hope this makes sense.
We are creating html Table dynamically on the basis of data fetched from database and assigned id to each Cell while creating them dynamically. But the problem is how to access values in Cell. Because we are not able to get id of Runtime generated TD.
