I need a way to show the display for an element in my list view like so:
[Code]....
Would it be possible to pass in a model to the DisplayFor method?
Maybe a syntax like this:
public static MvcHtmlString DisplayFor<TParentModel, TModel, TValue>(this HtmlHelper<TParentModel> html, TModel model, Expression<Func<TModel, TValue>> expression);
<%: Html.DisplayFor(item, i => i.BarBaz) %>
I'm having trouble with something that is (or should be) fairly straight-forward.
I have a recursive method that traverses an XML file, writing out the element tag names and values.
This is a snippet from the XML file:
[code]
<root>
<all_companies>
<company_group company_group_ID_attr="1">
<company_group_name>Cleaning</company_group_name>
<company_group_ID>1</company_group_ID>
<company company_ID_attr="2">
<name>Bloomburg</name>
<company_ID>2</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>4</employee_ref>
</employee_refs>
</company>
<company company_ID_attr="4">
<name>Morris</name>
<company_ID>4</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>3</employee_ref>
<employee_ref>1</employee_ref>
</employee_refs>
</company>
<company company_ID_attr="7">
<name>Ajax</name>
<company_ID>7</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>4</employee_ref>
<employee_ref>2</employee_ref>
</employee_refs>
</company>
</company_group>
</all_companies>
</root>
[/code]
I use the following XPath expression to access the first <company group> tag:
"root[1]/all_companies[1]/company_group[1]"
On the first call to the recursive method ("swrite_for_select_certain_stuff"),I see with the debugger that I reach the <company_group_name> tag. A recursive call at that point takes me to the text node within the tag ("Cleaning"), but it is a text type node (not an element), so it returns without writing anything to the output stream.
On return from that second call, things go wrong. The Iterator within the while loop returns false for the MoveNext method, when it should have moved to the <company_group_ID> tag (or so I think it should).
Am I missing something here?
OS is Win XP, and .NET is version 4.0.
My code is as follows:
[Code]....
I have a list of Key/Value pairs. basically its a List where ViewModel is a custom class of the form
public class ViewModel
{
public String Key { get; set; }
public String Value { get; set; }
}
In the View i would need to render Label and Textbox for Key and Value respectively.Im trying to use Html.DisplayFor() however it goes with model and only displays the properties of the model and not the list.I would like to achieve something of the format
<% foreach (var item in Model) { %>
<tr>
<td>
<%:Html.Display("item")%> [code]....
Im using asp.net mvc 2. I have a model Supermodel that consists of 2 models TestModel1 and TestModel2. In SuperModelView Im doing the following thing:
<%: Html.DisplayFor(x=> x.TestModel1, "TestModel1Template") %>
Its working just fine, except for the fact, that dropdownlist is populated but selected value is not set.Im using the following code for a dropdownlist in my template:
<%: Html.DropDownListFor(x=> x.Property1, (IEnumerable<SelectListItem>)ViewData["MyDDLList"], Model.Property1) %>
and its not setting the selected property. I put the code below to SuperModelView, that calls <%: Html.DisplayFor To populate the template and it works just fine.
<%: Html.DropDownListFor(x=> x.TestModel1.Property1, (IEnumerable<SelectListItem>)ViewData["MyDDLList"], Model.TestModel1.Property1) %>
UPDATE: I`ve tried to investigate the issue, but something is totally wrong. I can share the whole code, not sure where to put it, here or attach with separate files.
@Darin, what other parts should I share, or just share the whole model view and controller files?

View 6 RepliesIn my app I have a criteria builder section that's built using jquery and is pitched back to the controller in a form post and picked up as IList by the model binder as suggested in Phil's post here: http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx A really simple way that I'm persisting the criteria across posts is re-delivering the IList object to the view. I'm using a DisplayFor() template for this object, but because it's a list I need to know the index # inside of the template.
View 1 Repliesi use the Html.LabelFor method for displaying the property names and Html.DisplayFor for the property values of my model.
Unfortunately i cannot use the following format:
Title: value...
Description: value...
since the LabelFor method inserts a line break, so the result returned is like:
Title
: value...
Description
: value
How could i get rid of the extra line break?
do you think it would be difficult to write a framework where mvc compares last html it output to the current html we want to output, and instead of sending the entire html, figure out what has changed and generate js code that will do the updating as compared to previous html? (presuming nothing was manually changed on the client using js).
View 2 RepliesThe following seems reasonable, but it returns an error:
<asp:Repeater ID="RepeaterF" runat="server" DataSourceID="DSF" >
<ItemTemplate>
<%
If Eval("Item_Batch") = 0 Then
%><tr><td></td><td colspan="2"></td><td></td></tr><%
Else %>........
Error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.
how can i passing a value form ActionResult to html.textbox or Html.TextBoxFor in View
View 2 RepliesI have to break a HTML content string in to multiple lines. And each line should have some fixed characters, 50 or 60 Also I don't want to break the word..or html tags...

I am working on an ASP.NET MVC 2 project with VS 2010 and out of nothing I get the following errors on my views:
The name 'Html' does not exist in the current context
The name 'Model' does not exist in the current context
It is like it is not recongnizing the MVC Html and Model classes.
I have System.Web.Mvc on my references and on Web.Config I have:
[Code]....
I want to catch the html button click event on a class file including html text box value..
[code]....
I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:
function setData(associateValue, reviewDateValue) {
var associate = document.getElementById("Associate");
var reviewDate = document.getElementById("ReviewDate");
associate.value = associateValue;
reviewDate.value = reviewDateValue;
}
Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>
The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<% String functionCall = String.Format("setData('{0}','{1}')", Html.Encode(item.Associate), Html.Encode(item.ReviewDate )) ; %>
<%= Html.RadioButton("Selected", item.Selected, new { onClick=functionCall } )%>
I have some data which is HTML format saved in database. Like the chat as follows.

But it gets saved in some HTML format in Database as follows.
[code]....
So, Is there any ways that I can show this in Text box as what I need. While debugging the code, when I did HTML Visulaliser, it showed me correct format. How can I achive this in my Textbox control.
I have a Microsoft MVC project with an action "Foo" whose view ("Foo.aspx") contains the lines:
<%= Html.ActionLink("mylinktext1", "bar") %>
<%= Html.ActionLink<MyController>(x => x.Bar(), "mylinktext2") %>
When I hit this from a web browser or load it from an AJAX call, it properly returns:
<a href="/bar">mylinktext1</a>
<a href="/Bar">mylinktext2</a>
But when I call the action from another view like this:
<% Html.RenderAction<MyController>(x => x.Foo()); %>
Then the links are rendered without targets.
<a href="">mylinktext1</a>
<a href="">mylinktext2</a>
Why would this be happening, and how do I work around it?
Can I integrate Html.CheckBoxFor and Html.LabelFor to create the following:

What type of variable should I pass in the model to hold the choises?
I have a textbox which I need to enter html code into (like < strong> or < em> for example).The trouble is this is causing an error writing this back to the database. A potentially dangerous Request.Form value was detected from the client (tbVOther="< strong>testIs there a way around this without turning off the request validation setting?
View 3 RepliesI am attempting to replace this god awful collection of regular expressions that is currently used to clean up blocks of poorly formed HTML and stumbled upon the HTML Agility Pack for C#. It looks very powerful but yet, I couldn't find an example of how I want to use the pack which, in my mind, would be a desired functionality included in it. I am sure I am an idiot and cannot find a suitable method in the documentation. I had the following html:

View 1 Repliesanyone knows how to replace a html tag in a string with specific characters:
e.g.
string s1 = "<span style="italic">inluding <span style="bold">other</span> tags </span>";
string s2 = "<span style="italic">inluding </span><span style="bold">other tags </span>";
i want to replace "span" with "bold" to "bOpen" and "bClose" and to replace "span" with "italic" to "iOpen" and "iClose" in both c# and javascript.
i did use regular expression to do that: res = Regex.Replace(res, ".*?", replaceHtmlBold); but it cant match the nested tag and none-nested tag at the same time.
is this right? i am trying to display value in input box dynamically?
can anyone advice me is this corect approach? but still I am getting here only + + in input box?
So, I am having a hard time getting this to work. I am trying to add some typographic HTML codes to some labels I have strongly typed to my model.
<%: Html.LabelFor(m => m.Name) %>
I am using data annotations to customize the DisplayName of the property:
[DisplayName("Your friend’s name")]
public string Name { get; set; }
However the actual code is being displayed for the label:
Your friend’s name
I have also tried just using the old write method:
<%= Html.LabelFor(m => m.Name) %>
It's a little unclear for me on when to use a custom helper method and when to use RenderAction and also when to simply use ViewData instead. Some of their functions overlap slightly.
For example, if I were to create a Category navigation bar, would I create a new helper method and place that in some partial view? I had initially though of doing this, but I read on some blog to use RenderAction instead.
Assume the list of categories is coming from some data source.
I have a comment form inside the blog posts. in the form, if the user is authenticated, I will assign the values of the user into textboxes. that part is as follows;
[Code]....
But when I add HTML.TextBox instead of HTML.TextBoxFor, I am not getting validation if the user erase the fileds. Also, this form is inside the indext page and it is related to another action as follows;
[Code]....
so I cannot assign ModelState.AddModelError from controller.
What should I do here.
