I have an odd error with an ASP.NET web page (ASP.NET 2.0, C#). For several users at one customer location, on one part of one page, HTML content and attributes are being stripped out. So, something that should look like this:
<p class="adminmainlink">
<a href="ad_resourcewizard.aspx">Add or edit resources</a>
<script type="text/javascript">

- I've created a Survey with multiple sections in it
- The answer types are variable and, thus, the controls are created dynamically
- I have a Repeater where each RepeaterItem corresponds to a Category. (I have 5 categories in my current test, so I have 5 DataItems in the Repeater) Each RepeaterItem contains another Repeater which will hold the Question / Answer values
- After I data bind the Category Repeater, I loop through each RepeaterItem, find the Repeater contained in each RepeaterItem, and DataBind() this second Repeater to a list of Questions
- After DataBinding the Repeater containing the Questions, I sent that Repeater object to another routine, which is where the Answer controls are dynamically created and added to a Panel inside each of this Repeater's RepeaterItems.
I am able to navigate back-and-forth among Categories, save / delete answers, and fill in answers for Surveys that were left incomplete when a user logs back in.
One of the the potential control types for an answer is a ComboBoxList.
Each Question has an option for answers that require a ComboBoxList called "MaxAnswers." When this value > 0, I inject a little javascript that prevents the user from selecting more boxes than the "MaxAnswers" value. This is done during the last step described above like so:
[Code]....
This appears to always be added regardless of how many questions I answer or don't answer or how many times or directions I navigate around inside the survey. (I can push "Back" and "Previous" buttons as well as jump directly to any individual category by clicking a LinkButton)
Another option for Questions requiring a CheckBoxList is to specify if the selection of a specific ListItem within the CheckBoxList should display a TextBox. (e.g. a selection of "Other" will display a TextBox for the user to write-in an answer) I want to prevent a post-back just to show/hide a TextBox, so I inject an onclick event attached to the specific ListItem to accomplish this. The following code appears as the very next routine following the code pasted above:
[Code]....
This also works the first time the page is loaded but not after any PostBacks...
The lblMessage.Text lines are written to the page after ever PostBack, the MaxAnswers routine correctly adds the onclick event to the necessary CheckBoxList controls, but the "fncShowFTB" event is not added. Viewing the HTML with Firebug does show the onclick the first time the page is loaded, but it's missing after every subsequent postback.
Can anyone see what I am doing wrong that causes me to lose this event?
The Firebug HTML on initial page load looks like:
<input type="checkbox" onclick="fncShowFTB(this,'FTB50');" name="dnn$ctr556$View$rptCategoryPanels$ctl02$rptQuestions$ctl11$ctl00$6" id="dnn_ctr556_View_rptCategoryPanels_ctl02_rptQuestions_ctl11_ctl00_6">
After PostBacks, it looks exactly the same except that the onlick event is missing.
I use shared hosting. I have set my page to be cached indefinitely. The page gets cached after the first request. However on the next day when I visit my site it is no longer in the cache and has to be regenerated.
What is happening? Is the hosting removing my pages from the cache? Or something else?
I am new to jQuery. i place the return false to stop postback, that postback is stopped, but error messages are appearing. How can disappear the message by click cancel button. I used e.preventDefault() also it not working.
here my code:
<script type="text/jscript" language="javascript">
$(document).ready(function (e) {
$("#aspnetForm").validate({

Using VS 2010 RC, VB, I have a label on a masterpage that is hidden. I want to make it visible from a content page when needed, and have the text change on the label as well from the master page.
I am using the following to access the label, but the text and other properties don't change for some reason.
Dim lblErrorMessage As Label lblErrorMessage = CType(Master.FindControl("lblErrorMessage1"), Label)
lblErrorMessage.Style.Add("display", "inline")
lblErrorMessage.Text = "LoginID ALREADY EXISTS!!! Please choose a different ID"
I have a create view that I cannot set HTML attributes on. I have tried various ways but still cant set an attribute. Currently I'm trying this
<%: Html.TextBoxFor(model => model.itinerary, new { size = 60})%>
I wish to use the same form for adding and editing records within a database using a partial view. I understand that this is fine as the standard Html.BeginForm automatically output the correct html depending on the action that is being used (Add / Edit). However, I need to out said form with some extra HTML attributes. There does not appear to be an overload that allows this to happen without also specifying the ACTION and CONTROLLER names. If I hardcode these then surely I cant use the same form for edit and add automatically? Or am I missing something?
View 1 RepliesI need to add some attributes [URL] to the tag in an ASP.NET Page object. Note: I cannot do this in a declarative manner and have to use the server side object model to do it.
To add some additional information:
I need to do this within the ASP.NET Page rendering life cycle.
I need to add the attribute to the root element in the page.
Check out the following: <a href="/test?x=@if (Model.IsTest) { @(1) } else { @(4) }"></a> Is there a better way to write this instead of the @(1) and @(4)?
View 1 Repliesi used Html Helpers TextBox like this
<%= Html.TextBoxFor(model => model.Password)%>
now have can i access to attributes
i need to enable=false that control.
tried many approaches like below to determine which web page form buttons are checked and then get all the attributes for those checked buttons, getting nowhere fast, note on the sample code below, a button was checked but nothing was found with this code,
there's got to be a way to this, yes?
Dim MyControl As Control
Dim MyRadioButton As RadioButton
For Each MyControl In Page.Controls
If MyControl.GetType().FullName.ToString = "System.Web.UI.WebControls.radio" Then
MyRadioButton = MyControl
If MyRadioButton.Checked = True Then
foo = MyRadioButton.Attributes("name")
End If
End If
Next
this is what the radio buttons are like they have unique id's and values, its the name attribute that groups them
<input id="class01" name="class01" runat="server" value="class01" type="radio"/>some text<br/>
<input id="class02" name="class01" runat="server" value="class02" type="radio"/>some text<br/>
I would like to add html attributes to form inputs, specifically disabled="disabled" in addition to others. I have conditional logic in the Controller that determines whether to add this html attribute or not that sets a bool IsDisabled flag in my ViewModel e.g.
class ViewModel
{
bool IsDisabled {get;set;}
}
So in my View, I want to do something like:
<%= Html.TextBoxFor(x => x.Data, new {maxlength = 30, IsDisabled ? disabled = "disabled": null}) %>
or rather something like
<%= Html.TextBoxFor(x => x.Data, new Dictionary<string, object>().Add("maxlength", "30").AddConditional("disabled", "disabled", IsDisabled) %>
Except that Add returns void, and there is no such thing as AddConditional. Is there something like an MVC HtmlAttributeBuilder class, or should I just extend Dictionary with these two extension methods?
I have a form that should have all html elements disabled unless a user id is present, indicating that a user has been loaded for editing. I've done this, which works:
[Code]....
This works, and all is good. I couldn't set an if statement up to control creation of the entire Html.BeginForm, which was a bit of a pain. When I tried, the View thought I was creating 2 form begin tags with only one end tag, even though it was inside a conditional statement. Whatever. The problem I now have is that I need to assign an id for the form to work with a validation plugin. I can't add the id = "someID" inside of the condition, because it won't be available when the user id is present, which completely defeats the purpose. I can't move the ternary condition to inside of the 'new' statement - I tried. I thought this would work:
[Code]....
But no dice. I get the following error: Type of conditional expression cannot be determined because there is no implicit conversion between 'AnonymousType#1' and 'AnonymousType#2'. What? Seriously? I'm not trying to convert anything. I'm either assigning a new html attributes section with one set of values or another set of values. Since I can't perform the conditional logic inside of the 'new' statement, I have to recreate the entire 'new' statement after the condition is tested, but this still doesn't work, as I get the aforementioned error. As a short-term fix, I'm going to just render an actual html form tag with the required data, but I'd like to know why it is that code executed/rendered within conditional statements doesn't understand that both true and false results aren't running, and also how to fix this issue while still using the Html.BeginForm helper.
I have a HyperLink on my usercontrol in which I set onlick event dynamically on the server side like this:
this.Attributes["onclick"] = string.Format("javascript:alert('{0}')", base.NavigateUrl);
The problem is that when Asp.net renders the page, it ends up with something like this
<a href='...' onclick="javascript:alert('TEST')>LINK</a>
which obviously is not valid Javascript. Using " instead of ' wouldn't help neither, the generated HTML is alert("TEST")
I will be getting data through wcf service coming form commerce server (instead of DB). Data which is coming will be in the form big html content with all html tags or may be a single line sentence. I should display this dynamic data into the placeholder in the content page (master content page). I have been trying but not able to load when the data is in the form of HTML page. html content or may be single lline of senetence.

With this bare bones control, it would render the root element as a Div tag. But how can I add attributes to that root HTML element that this control will render .
i am working an asp.net mvc 2 web app using model metadata and some of the model metadata don't seem to work when using the default Html.EditorForModel().For example, when applying the DefaultValue(1) and the ReadOnly(true) attributes on a model field, the field displayed on edit view has zero for its default value and it is not read only.

I am using DataAnnotations to supply information for Inserting/Editing data into a grid. Is there a way to control the Html attributes of the DisplayNames I use, so that, for instance, the DisplayNames can be a different color from the text in the textboxes?
View 1 RepliesI have implemented a custom ModelMetadataProvider so that I can decorate my view models with some custom attributes and everything was working fine until I made use of a Partial View. The following code in my view works fine: -
<%: Html.DisplayFor(x => x.Results) %>
Results is a List which renders a custom display template and is also decorated with a custom attribute. Using breakpoints, after the above line and prior to the code within the custom display template, the overridden CreateMetadata method in my custom ModelMetadataProvider is invoked. If I look at the attributes collection parameter I can see that it does contain my custom attribute thus everything working as expected. However, if I replace the above with the following line of code in my view then it breaks: -
<% Html.RenderPartial("ApplicationSearchResults", Model.Results, new ViewDataDictionary()); %>
All the Partial View contains is: -
<%: Html.DisplayFor(x => x) %>
Again using breakpoints, after the above line and prior to the code within the custom display template, the overridden CreateMetadata method in my custom ModelMetadataProvider is invoked. But this time if I look at the attributes collection parameter my custom attribute is not there.
I'm pretty new to MVC 2 using the Entity Framework. I have two tables Company {ID int identity PK,Name nvarchar} and User {ID int identity PK,UserName nvarchar,CompanyID int FK}. A Foreign Key exists between User and Company.I generated my ADO.NET Entity Data Model, a Controller and a view to insert a record. My HTML form has the fields Company and UserName and the is when I click save a Company and User is inserted into the database. Sounds straight forward right!
My question is as follows:
I created a strongly-typed view derived from my 'User' entity. I'm using the the html helper Html.TextBoxFor(model => model.Organisation.Name) but the html name attribute for this input field is 'Organisation.Name'. My problem with this is that the dot throws up all sorts of issues in JQuery, which sees this as a property. If I want to change the name I read that I can use DataAnnotations but because I used the Entity Designer this involves using Buddy Classes. Seems like a bit of overkill just to change the html name attribute on this input field.
In VS2008, it used to be that whenever I was typing an html attribute in an .aspx page when I hit '=' a pair of double quotes was automatically inserted and the cursor placed inside them. I guess I've changed a setting, but I don't know what to change to get that functionality back. I am using Resharper if it makes a difference.

But when I view the page, this content comes out first, before even the tag.
how to get this code inline instead?
I have a user control that displays a list of records. Users have the ability to open an embedded user control with a FormView to either add a new record or to edit an existing one. The UserControl with the FormView has a button that closes and hides the user control.
If the user control with the FormView is opened to edit a record, the code works fine. But if the UserControl is opened directly into Insert mode, the code craps out
