how one might go about implementing your own custom tags in JS pages served by ASP.NET?
Basically what I am looking to achieve is a way of creating "includes" for my Javascript files by adding some code such as.
//Include Src="MyJavascriptFileLocation.JS"
And then having the ASP.Net handler serve my javascript file but also dynamically append the referenced javascript file to the location where the include is written.
I am trying out some code which enables me in creating a page with extension .asp2
The tags included will also be custom, something like:
[code]....
I have done the necessary changes so that ASP.NET identifies the extension. I have also kept a mapping of custom tags and asp.net/html tags with myself. With this I am able to render the page on browser. But how can we do event handling(usually done by page postbacks and code) in such a scenario?
In ASP.Net I have a few custom controls I've made. I utilized jQuery where it helped also. Well, one problem I have now(with obvious, but "bad" workarounds) is that for each user control I need to execute some code from within pageLoad($(document).ready will not work with update panels). Well so now my problem. I need to have two custom controls attach to the pageLoad event. What would be the best way of doing this? I can't just do
old_pageLoad=pageLoad
pageLoad=function(){... old_pageLoad();}
because these custom controls can be used more than once on a page and the script needs to run for every single instance of the control, plus what if I had 3 different custom controls on the page? the only method I've come up with is something like this which seems super hackish:
old_pageLoad_<%= MyStaticClass.GetUniqueID() %>=pageLoad;
pageLoad=function(){... old_pageLoad_<%= MyStaticClass.GetUniqueID() %>();}
Are there any better ways of handling function conflicts like this? I have also seen this MSDN article but what it suggests doing seems worse to me than what I am currently doing.
I am creating a custom control and was wondering if it is possible to render any JavaScript in the head tags of the page it is placed on? I am thinking I would need to use the FindControl method, but am not sure what I need to bind to. I am thinking the page object? Let me know if I am thinking in the right direction or if there is another option.
My only concern with the above mentioned idea is that how do I render all my content while placing some code in the head tags?
How can I remove all html tags and script tags? consider also short tags like unclosed tags
<script>blah...</script>
<body> aaa<b>bbb</body>
This should return aaa bbb.
notice that all the contents inside the script tag is ignored.
In my blog application, I am storing the tags of a blog post in a column like this;
tag 1; tag 2; tag 3;
I will have hundereds of blog posts and I would like to display all tags in a page and I would like to open a page like ~/tags/tag-1
and under this page I would like to list the blog posts which has the value of the tag. in this case it is tag-1
what do you think is the best way here to handle this kind of thing?
I'm creating a custom ASP.Net GridView and I want to be able to alter the __EVENTARGUMENT value but I can't figure out how to capture the returned value on the server side.
I'm creating the ability to have a collapsible representation, so the first level is the standard GridView and I will insert additional rows via JavaScript if they expand the first level row.
My problem is how to create a link on the selecond level rows that posts back with custom data.
I know it is possible to add custom headers via the httpProtocol >>customHeaders section of the web.config for 2.0+ sites but this is not allowed on 1.1. Is there an easy way to add meta tags to all pages of a site? I've already tried the httpHeaders tab in iis(6) but with no luck.
I need to force ie7 mode on ie8 for all pages of my 1.1 sites.
I've just finished and published my most recent version of
[URL]
but when I try to validate the website using http://validator.w3.org it is giving me few errors.
I noticed that I have multiple <title> tags in my pages and reason for that is because I am using master pages. What happened is my master pages are using <head> tag and <title> tag inside, then default page will have <asp:content ID="Content2" runat="server" contentplaceholderid="head"> and here I'll have another <title> tag.
The question is obviously I am having duplicate <title> tags across my entire website. Which <title> tags should I remove, the one in <head> tag of my master page, or the one on every other page such as one specified in default.aspx?
I would think that master page should not have the title and any other meta tags such as <meta name = "keywoards", "description" etc since I am repeating it in all other pages but is my thinking correct?
I'm currently using ASP.NET MVC 2 and the spark view engine. The main master page (application.spark) contains all of the CSS link tags that need to be present for all pages (global stuff). However, I have some content pages that have page specific CSS tags and currently I'm just sticking the link tag in the body as something like:
<content name="MainContent">
<!-- page specific csss -->
<link rel="stylesheet" href="/Content/css/page_specific.css" />
My problem is that when the page renders, this tag ends up in the which is not where it needs to be. Is there a solution for this?
I had was to check the controller in the Application.spark page and write out which page specific css file is required for that particular controller, however, that solution doesn't seem to scale well and I would imagine there is some way of creating the link in the child page and having it render where it's supposed to by the browser.
I have Created a custom CheckboxList as [Code]....
but when i am passing this cutom control another page via parameter to newxt page i am not able get the selected checkbox
Im using code like this :
<li id="x" runat="server" code="myCode"> ...
Is it possible to iterate through each control on the site check if it has got code attribute and if yes process it it any way ?
Im using asp.net 2.0 attempts in castings return null so that I dont have control over attributes
foreach (object control in this.Controls.ToString())
{
HtmlGenericControl gc = control as HtmlGenericControl;
if(gc != null)
{
if(gc.Attributes["code"] != null) ...
the code below doesnt enter into if. All
I have read your article from aspsnippets.com about custom paging it really work, but there are a problem that if there are more record in database (2000 to 5000) than number of page index will be goes in large number. like 1 to 200, any way which can divide it like 12345678910...2000.

I have a custom control which contains (amongst other things) an imageButton.
I'm adding a handler to the "click" event of the imageButton however when the button is clicked the handler routine is not called. where I am going wrong with this? should I be handling the click event in some other way?
here is my code:

I am trying to write a webservice that's going to be used through ASP.Net Ajax. In this webservice I have to add exception handling so that in case of any error, I could log them to some central place and then throw.
In my other areas of code (like aspx pages), i have been using a basepage which Overrides System.Web.UI.Page class's OnError by adding a custom event handler. I want to do the same for my webservice as well.
Basically I do not want to decorate each webservice method with a Try Catch block. Instead if there is a clean way like to override the on error method, i want to go for that. Unfortunately the WebService class does not seem to have any functionality for this.
I have a web page with 5 textboxes (for branch_id, street, city, state, and zip) and a button. When data is entered in the textboxes, the button is clicked and the data is populated in the database. I have the sql INSERT statement ("insert into branch values(:branch_id,
location_type(:street, :city, :state, :zip), staff_nested())") in both the SELECT command and INSERT command. It was originally in just the SELECT command, but I also added into the INSERT command in case I need to do something in the on_insert or on_inserting event. I'm not sure if that would actually work since I click the button to enter.
Anyway, if a duplicate key is entered in branch_id the error "ORA-00001: Unique constraint violated" is raised. I would like to change this and put my own error message, such as "ID is already used, select another." What I have so far is below. I do still get the same message.

Now, How can I Parse it and render it in RenderContent method ? !!!
The following method is always throw the first Exception, it means this.Controls is always empty !!! How can I do it and how I can access to the nested children in RenderControl method ?
public class Menu : WebControl
{
....
public override void RenderControl(HtmlTextWriter output)
{
if (!this.HasControls())
throw new Exception("Controls are empty");
....
}
}
I am creating a webform in which I am having two radio buttons (Yes/No), one textbox, and two lables.
I want to enable and disable the textbox on radio button click Yes and No respectively.
I want to use custom server control for this whole process as we have to use this DLL in other application also.
Being as beginner I got just confused about event handling methods for server controls.
I have a custom ascx user control on my page that includes a dropdownlist. There is an onSelectedIndexChanged event handler that is connected to this dropdownlist. The first time the user selects a value, the page does a postback and the logic executes correctly. However, if the user then goes to change their selection, the event handler does not get triggered.
View 3 RepliesI'm using DotNetOpenAuth as my membership system, and the way I have it working now seems to be working quite well. What I'd like to do however is build into my website the ability to check user credentials against the AuthCookie rather than a session. In the membership provider, I can check for the username like this
string UserName = System.Web.HttpContext.Current.User.Identity.Name;
''# which returns the OpenId ClaimedIdentifier
What I'm wondering is if there is a way to extend this so that I can retrieve custom properties from the AuthCookie rather than having to create my own session object. Currently I have this setup.
UserSessionModal
Namespace Domain
Public Class UserSessionModel
Public Property ID As Integer
Public Property RegionID As Integer
Public Property Username As String
Public Property Slug As String
Public Sub New(ByVal user As User)
_ID = user.ID
_RegionID = user.RegionID
_Username = user.UserName
_Slug = Replace(user.UserName, " ", "-")
End Sub
End Class
End Namespace
BaseController (inherited by all controllers)
Protected Overrides Function CreateActionInvoker() As System.Web.Mvc.IActionInvoker
''# Create a UserInfo object for the logged in user
''# and store it in a session state.
If Session("UserInfo") Is Nothing AndAlso User.Identity.IsAuthenticated Then
Dim user As Domain.UserSessionModel = New Domain.UserSessionModel(OpenIdService.GetOpenId(HttpContext.User.Identity.Name).User)
Session("UserInfo") = user
End If
Return MyBase.CreateActionInvoker()
End Function
Then in my views I do something like this
<%
Dim user As MyApp.Core.Domain.UserSessionModel = DirectCast(Session("UserInfo"), MyApp.Core.Domain.UserSessionModel)
%>
<%: Html.ActionLink(user.UserName, "Details", "Users", New With {.id = user.ID, .slug = user.Slug}, Nothing)%>
What I really need to be able to do is remove the Session stuff all together and just simply check the AuthCookie for my custom properties ID, RegionID, Username, and Slug. I can already get the "ClaimedIdentifier" out of the AuthCookie using HttpContext.User.Identity.Name... I just need to be able to extend it.
I created a customDropdown usercontrol with Events and It worked fine.
Now I stored the path of the ascx file in the database table and i want to Load the ascx file and handle the Events dynamically in an aspx page.
To Load the usercontrol and access the public properties and method, I need to know the object i am trying to load, right?
For Example
FeaturedDDL c = (FeaturedDDL)Page.LoadControl("~/FeaturedDDL.ascx").
But I dont want to hardcode objectType "FeaturedDDL", coz i dont have that stored in my Database field.
Since I am loading the usercontrol by getting the path and name of the usercontrol from the database table,how will I know the ObjectType at that time?
How to accomplish that and also how to handle the events for these type of situation?
if there is there away in javascript to remove any tags that are <h1 /> <h2 /> <h3 /> <h4 /> etc from the HTML editor?i use javascript function below to insert my custom styles from outside the editor, so at the end i need a way to searh all the content and remove the unwanted tags that are created by the editor?

I am trying to build a white list. I am using html agility pack to remove all tags I do not allow. however this only gets ride of these type of script tags

I have custom errors set in the web config file as follows:
<customErrors mode="RemoteOnly" defaultRedirect="GenericError.aspx" />
Fine and dandy... I like that mode="RemoteOnly" facilitates development...
For unhandled exceptions, I have in global.asax:
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
Response.Redirect("GenericError.aspx")
End Sub
However, unhandled exceptions are going to the generic error page instead of the informative yellow screen of death preferred by developers. I can comment out the redirect in global.asax, but then I need to remember to change it for the production environment. Is there a way I can check in Application_Error whether I am remote or not to determine whether to redirect?
