C# - Call To Render Partial Not Working After MVC 2?
Jan 28, 2010
I was calling render partial like this in MVC 1.0:
<% Html.RenderPartial("~/views/shared/categories.ascx", ViewData.Model.Categories); %>
Now after dropping MVC 2.0 .dll's, I am getting the error:
CS1061: 'object' does not contain a definition for 'Categories' and no extension method 'Categories' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)
Do I have to update my solution or anything going from mvc 1 to 2?

I'm trying to figure out if there's a good way to remove the duplication in this scenario. Here's the model ... a Person that contains two Addresses:
[Code]....
And here's the view:
[Code]....
The entire Address block is duplicated ... one for the Home address, one for the Work address. To remove duplication, I tried factoring out the Address block into a partial view, and doing this in place of the two divs above:
[Code]....
And the page renders fine, but when it gets posted back on form submit, the model binding doesn't work. (Of course it doesn't work ... the <input> tags for the address blocks both have name="Street", so there's no way for the model binder to know whether to shove that into HomeAddress or WorkAddress.)
I read this post:
[URL] but that answer seems most unsatisfactory. Is there a better solution?

to update a part of form before the request completes?for example, I have placed following code in button1_click
lbl1.text = "1"
system.threading.thread.sleep(2000)
lbl1.text = "2"[code]...
so what i want is, lbl1's value should be changed to 1 then to 2 after 2 second and then to 3 after another 2 seconds, rather than waiting for whole procedue completion.i had also tried to write this value to session and try to update these values from timer controlled updatepanel but it turned out that session are sent/set only when whole request is complete.

I am trying to implement something like Ruby on Rail's ActionDispatch::Flash to pass messages to the next page request. The approach that I want to take is to store a pair of (partial view name, model object) in the session context and render it in the master page when rendering the request to display the flash message.
Inside my HttpApplication subclass I now have:
[Code]....
to render the partial view that was specified by name when Global#Flash was called.
I want to use a view for the flash message instead of saving the message as a string in the session context because I want to include the URL in the message:
<%-- BookmarkAddedFlash.ascx --%>
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyApp.Web.Models.Bookmark_AddModel>" %>
<%: Html.DisplayTextFor(m => m.Url) %> was successfully bookmarked.
And I only want to render the view when the subsequent request is made; i.e. one request sets the flash message and the subsequent request renders it.

I'll give a very simple example:
at the moment I have to write like this:
<% Html.RenderPartial("hello", new HelloInput { Name = "Jimmy" } ); %>
I would like to be able to like this:
<%=Html.Hello("Jimmy") %>
So I would like to know how create this helper:
public static string Hello(this HtmlHelper helper, string name)
{
return the result of rendering partial view "hello" with HelloInput{ Name = name };
}

I am using tabs and I want some user input on each one.hen I click submit I return the partial view. However it is only the partial view that gets rendered.What I am trying to do is keep the overall view and render the partial view. In fact what I am trying to do is known as hijaxing, but I am not familiar enough with Ajax that I know how to do it.So this is my view;
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Employee.Master" Inherits="System.Web.Mvc.ViewPage<SHP.WebUI.Models.HolidayRequestViewModel>" %><asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> HolidayRequest</asp:Content><asp:Content
ID="Content2" ContentPlaceHolderID="EmployeeContent" runat="server"> <% using (Html.BeginForm()) {%> <%: Html.AntiForgeryToken() %> <h2>Holiday Request</h2> <p>You have <%: Html.DisplayFor(model => model.DaysAvailableThisYear) %> days left annual leave for this year and <%: Html.DisplayFor(model => model.DaysAvailableNextYear) %> days left for next year.</p> <p>If your request is approved and exceeds the number of days left, then those extra days will not be paid.</p> <%: Html.HiddenFor(x => x.EmployeeId) %><%: Html.HiddenFor(x => x.ApproverId) %> <% } %> <div id="tabs"> <ul> <li><a href="#tabs-1">Approver</a></li> <li><a href="#tabs-2">Single Date</a></li> <li><a href="#tabs-3">Date Range</a></li> </ul> <div id="tabs-1"> <% Html.RenderPartial("GetApproverTab", Model); %> </div> <div id="tabs-2"> <% Html.RenderPartial("GetSingleDateTab", Model); %> </div> <div id="tabs-3"> <% Html.RenderPartial("GetDateRangeTab", Model); %> </div> </div></asp:Content>
This is my partial view;
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<SHP.WebUI.Models.HolidayRequestViewModel>" %><% using (Html.BeginForm("GetSingleDateTab", "Employee", FormMethod.Post, new { id = "frmSingleDate" })) { %><p>Enter your day or part day of Annual Leave here.</p><table> <tr> <td align="right">Date:</td> <td><%: Html.EditorFor(x => x.SingleDate) %></td> </tr> <tr> <td align="right">Morning Only:</td> <td><%: Html.CheckBoxFor(x => x.MorningOnlyFlag) %></td> </tr> <tr> <td align="right">Afternoon Only:</td> <td><%: Html.CheckBoxFor(x => x.MorningOnlyFlag) %></td> </tr> <tr> <td colspan="2" align="center"><input type="submit" value="Save" /></td> </tr></table><%: Html.HiddenFor(x => x.EmployeeId) %><%: Html.HiddenFor(x => x.ApproverId) %> <% } %>
and this is my controller;

I am totally a new bee in asp.net mvc. Let me now explain my issue. I have a strongly typed view which inherits from a view model Document. I want to have a partial view in that view itself. My code for this purpose is :

I have a list of items that loads when I call the page controller and I have an Ajax.BeginForm that calls the same (Index) Action. If the Action sees that it's an Ajax request (Request.IsAjaxRequest()) then it returns a partial view. I even have a div that contains a message about the results loading. That all works fine, but my results can sometimes take awhile and I'd like to hit the page first and then make the Ajax request so the user sees the page quickly and sees the "loading" message. I know I could click my filter button (triggering the ajax call) using jquery on document.ready, but is there a more MVC way to do this?

[URL] .... am using this functionality in my project and it is working very fine but i am facing very strange issue while using this.
The above functionality is not working when we place dropdownlist and textbox inside updatePanel and ModalPopupExtender
The .aspx page where i am using ModalpopupExtender and UpdatePanel for DropDownList and Textbox is below
<%-- *************************** MODAL POPUP EXTENDER ***************************************************** --%>
<asp:HiddenField ID="HiddenField3" runat="server" />
<asp:HiddenField ID="HiddenField4" runat="server" />
<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Div6" TargetControlID="HiddenField3"
BackgroundCssClass="modalBackground" CancelControlID="bclosemodalpopup" >
</cc1:ModalPopupExtender>
[Code] ....
The above code is not working with UpdatePanel but it is working if we remove DropdownList and Textbox from updatepanel.
The javascript code which i am using is below
<script type = "text/javascript">
var ddlText, ddlValue, ddl, lblMesg;
function CacheItems() {
ddlText = new Array();

1) I have a "user control" (partial view) called LogIn where my users log in. It has the usual textbox/password/validators/etc.
2) I have one view called Account/LogOn.aspx that has the following code:
<% Html.RenderPartial("LogIn"); %>
3) I have another view called Home/Index.aspx that also has the following code:
<% Html.RenderPartial("LogIn"); %>
This renders a partial view inside my main views. When a user logs on, he/she is redirected to Home/Index.aspx
The problem:
I can log on from Account/LogOn.aspx, but I can't log on from called Home/Index.aspx. Why?

I am trying to render a partial view and i can not get it to work. Probably i am missing something trivial, because what i am trying to do is really simple.
I have two controllers: NewsController and CommentController. In the "Details" view of the NewsController i'd like to render the partial view "List" of CommentController. So in Details.aspx i have this line:[Code]....
However, this line throws an excpetion:
"The controller for path '/News/Details/e4243192-55ea-4cfb-b8d3-9714cca4ff08' was not found or does not implement IController."

I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?

I have the following entries in the css file.
a.intervalLinks { font-size:11px; font-weight:normal; color:#003399; text-decoration:underline; margin:0px 16px 0px 0px; }
a.intervalLinks:link { text-decoration:underline; }
a.intervalLinks:hover { text-decoration:none; }
a.intervalLinks:visited { text-decoration:underline; }
a.selectedIntervalLink { font-size:12px; font-weight:bold; color:#003399; text-decoration:none; margin:0px 16px 0px 0px; }
a.intervalLinks:active { text-decoration:underline; font-size:large ; }
Edited for trial:
a.big-link:link{}
a.big-link:visited {}
a.big-link:hover{}
a.big-link:active{font-size:1em;}
Whenever i take the click on some links (not shown) which is embedded in the webpage ..i can see the change in the link
a.intervalLinks:active { text-decoration:underline; font-size:large ;
(the font of the link will become large)
but after clicking the page refreshes ..the changes will go away
i want to keep the change for ever in that link ...even there is a page refresh
i understood that ..this can achieved only throughg the code behind of asp.net
Following code should work:but unfortunately its not
protected override void OnInit(EventArgs e)
{
rptDeptList.ItemDataBound += new RepeaterItemEventHandler(rptDeptList_ItemDataBound);
}
void rptDeptList_ItemDataBound(object sender, RepeaterItemEventArgs e)
