I am using Javascript to create dynamic controls on the page I am not dealing with File Uploads, just creating custom field things.
I think I need to override SaveViewState and LoadViewState events to keep my controls in the ViewState.
I want to be able to extend the System.Web.UI.Page class and then easily access those properties from the Markup. I know I can do it from the codebehind, but is it possible from the Markup?
View 3 RepliesThere it is written that controls should be added in Init event rather than Load event for the added controls to participate in the Postback data processing.But whose Init or Load event ? Page's Init or the containing container's Init event?
View 3 RepliesIn my code behind (c#) I dynamically created some RadioButtonLists with more RadioButtons in each of them. I put all controls to a specific Panel.What I need to know is how to access those controls later as they are not created in .aspx file (with drag and drop from toolbox)?
I tried this:
foreach (Control child in panel.Controls)
{
Response.Write("test1");
[code]....
"test1" and "test2" dont show up in my page. That means something is wrong with this logic.
I have a GridView:

I have this LinkButton in the ItemTemplate section... I want to add a jQuery Popup when the user will click on it. The message that will be displayed depends of the value in the label. Is there a way I can do that?
I have a public property defined in code behind of a user control. I want to toggle visibility of controls in the markup based on the property's value.
However, using the following syntax:
<td style="display:<%#(Container.PageControlMode == PageControlMode. PageMode.Wizard) ? "none" : "inline" %;">
I have the following property in my code behind:
public PageMode PageControlMode { get; set; }
Does not work and generate errors.
I am dynamically creating controls from javascript. Now i want to access this is server side.
I assigned all the control values from dynamically created controls to hidden field and accessed that in server side. For this i need to create many hidden fields as much as dynamically added controls.
Ok, so I'm dynamically adding <input type="File" />'s to the page via button click, client-side via Javascript.
Now when I click the upload button I can access the PostedFiles server side, but I also have radio button lists that I've created dynamically as well with no runat="server".
If I were to .setAttribute("runat","server") for the radio lists I create, is there a way to access that client-side created server control, from the server side?

I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?

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.

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?
View 4 RepliesI 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 RepliesI 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...
I'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.
[Code]....
Probably a straightforward thing, or not intended usage at all,
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.
In a webforms application, it's possible to add a server control to the markup and then access that control from the corresponding code behind file, but I'm not sure of the MVC equivalent of this functionality.
I've been looking at some tutorials, and it appears that in MVC applications, instead of using server controls, the examples are using HTML helpers, such as Html.TextBox, etc.
However, while I can find examples html helpers in views, I can't find any examples of how these helpers are accessed in the controllers, so I've declared an Html.TextBox in my view but don't know how to access its value in the controller when I hit enter.
