When I do an Html.RenderAction( action, controller, new { varName = value } ); if the original request had a parameter equal to varName, then the value is not changed in a render action.
Example:
1. Post to "C1/A1" with a string var _test = "abc"
2. Inside C1/A1 get some data and return a partial view
3. Inside the partial view I invoke an action on another controller. The action has an input variable with the same name and type (string _test) Html.RenderAction( "A2","C2", new {_test="fgh"});
4. the value in _test that arrives at C2/A2 is still "abc"
I've traced through it step by step, and the value used in the view render action call is correct, but in the next trace step, the value received at C2/A2 is incorrect.
If this is not an error, and creating a new route value to pass in render action is not the correct way to handle this, what is?
If I have a route mapped as follows, how can I add a constraint for the route values with periods in?

I have a field in a details view shown below
<asp:BoundField DataField="DTMON_F" HeaderText="Monday Hours From: " InsertVisible="False"
ReadOnly="True" SortExpression="HOURS" Visible="false" />
<asp:TemplateField HeaderText="Monday Hours From: " SortExpression="HOURS">
<EditItemTemplate>
<uc1:TimePicker ID="tpMondayHours" runat="server"/>
</EditItemTemplate>
<InsertItemTemplate>
<%-- <uc1:TimePicker runat="server" ID="tpMondayHours" />--%>
<asp:TextBox ID="txtMondayHours" runat="server" Text='<%# Bind("DTMON_F") %>'></asp:TextBox>
</InsertItemTemplate>
<ItemTemplate>
<asp:Label ID="lblMondayHours" runat="server" Text='<%# Bind("DTMON_F") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
Before "DTMON_F" is binded to the view I want to cut the string that is returned...Where and how might I do this?
I've got a route that I want to be able to pass nullable values to. I was using MVC 1 but updated my solution to MVC 2 to take advantage of UrlParameter.Optional.
My route look like:
[Code]....
Which works fine if I go to http://localhost:1234/Search.aspx/l-1/t-1/p-1/s-1 but when I go tohttp://localhost:1234/Search.aspx/l-/t-/p-1/s- or any combination with missing parameters I keep getting 404's.
Also on a related note since I've upgraded to MVC 2 I can no longer use RedirectToRoute for the above route I get the following error: No route in the route table matches the supplied values. Whereas in MVC 1 it would redirect to it without any problems.
Global.asax route values
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional, filterDate = DateTime.Now.AddDays(-1), filterLevel = "INFO" } // Parameter defaults
);
Here's my actionlink
@Html.ActionLink(item.MachineName, "Machine", new { id = item.MachineName, filterLevel = "hello" }, null)
When the filterlevel is specified in the actionlink, it generates a url like this: [URL] Which is the same page as I am currently on. If I change the actionlink to use a property other than one that has a default value in the route table (yes, if I use filterDate it messes up too), it generates a link like this:..............
in my mvc2 application i have an action link like

docid is set to empty string because i want to clear ambient value of docid that is present in request context. i have gone through a lot of material on internet and even tried docid=String.Empty but it does not solve the problem and gives me url like /controller/action/id?docid=x. i also write a routeconstraint as suggested but it did not solve the problem either.clear those route values comming from request context with html.actionLink. i don't want to use html.routeLink
I need to pass javascript function as a parameter value to the ajax actionlink in asp.net mvc app. how can we achieve this?
View 1 RepliesI have a post-only action that has a different route. In my form, I need to post to it, but also keep the querystring values I currently have.
Initial response: /my/first/path/?val1=hello
Needs to post to: /my/other/path/?val1=hello
It seems when I specify a route, it of course only returns the route and doesn't append the querystring values of my original page (for obvious reasons).Is it possible to cleanly append querystring values to my the action attribute of the form tag?
I tried to mix asp.net 4 webfrom and ASp.Net MVC 3. I add required lines in webconfig, but I've issues implementing route in global.asax
Currently I use several routes for webfroms. routs template are like below
routes.MapPageRoute("Node", _
"article/sport/{nID}/", _
"~/article/articleview.aspx")
I encounter error, when I add below lines to global.asax
routes.MapRoute( _
"Defaultss", _
"{controller}/{action}/{id}", _
New With {.controller = "Home", .action = "Index", .id = UrlParameter.Optional} _
)
I want to know how could I mix ASp.Net MVC routes with webforms routes.
when i run the app i got this error
A route named 'Admin_default' is already in the route collection. Route names must be unique.
Parameter name: name
this is my AdminAreaRegistration

I have a partial view that is rendered on a view. That partial view has textboxes in it. The user can enter values into them.
I need to put all the values from the textboxes in my partial view into an array, and then give the view (the parent page rendering that partial view) access to that array.
I have a url that I want to map routing to:
[URL]
where tabvalue is one of: "personal", "professional", "values" or nothing.
I want to map it to a route like:
Member/Edit/{tab}
But my problem is - I don't know how to specify such constraints. I'm trying this regex:
^[personal|professional|values]{0,1}$
but it only works when I use url
[URL]
[URL]
and doesn't work for
[URL]
how to specify the correct constraint?
P.S. I'm not using MVC, just asp.net WebForms
Is there any difference between accessing view data using HtmlHelper.ViewData vs. using HtmlHelper.ViewContext.ViewData?

This may be a really dumb question but when I try to access this field in the code behind file
<input ID="txtOldFile" type=file /> it says txtOldFile does not exist.
What I want to do is access a directory and select a file name which I will then use in code.
I have the following code for my page:
[Code]....
And the following .cs file associated with it:
[Code]....
I would like to be able to do the following in the .cs file for this page:
#1. Initially "Submit News" is disabled. The admin must click "Preview News" which will update the newslabel temporarily and also enable the "Submit News" button.
#2. When the "Submit News" button is clicked, the news.txt file should be opened and whatever content is currently in the newslabel.Text will be written to news.txt. The news will then be updated for anyone to see.
Right now, if I try to do "submitnews.Enabled = false;" is does not let me because it thinks that submitnews is not in the current context. Basically I need to know how to access elements that are within a <asp:LoginView> area.
I've got an .aspx page with this in it:
<%@ Import Namespace="System.Web.Mvc" %>
<%= AssetController.ScriptTag("/js/Community/CommunityWizard.js")%>
And I have an AssetController class:
Imports System.Web.Mvc
Public Class AssetController
Inherits Controller
Public Shared Function ScriptTag(ByVal src As String) As String
Return String.Format(
"<script type='text/javascript' src='/js.mvc?src={0}&{1}'></script>",
System.Web.HttpContext.Current.Server.UrlEncode(src),
New BuildVersion().ToString()
)
End Function
End Class
The project has a reference added to the 3.0.0.0 version of System.Web.Mvc assembly. When I try to view the page in a browser, I get a HTTP 500 with this message:
BC30007: Reference required to
assembly 'System.Web.Mvc,
Version=3.0.0.0,
Culture=neutral, PublicKeyToken=31bf3856ad364e35'
containing the base class
'System.Web.Mvc.Controller'. Add one to your project.
What gives? I don't understand why I can use this controller everywhere in our ASP.NET Forms/MVC hybrid application, but not in a view. EDIT: In fact, when I type <% System.Web. into the .aspx view, Mvc doesn't even appear in Intellisense!
Is there any way to access values in .vb and javascript files apart from hidden and cookie variables?
View 1 RepliesI would like to use the webconfig file to store some values, which will be used in my application in order to execute some methods, one a parameter for a timer, the Interval property and the other to pass as parameters in a method.
So, my questions are:
Where in the webconfig can save these parameters in order to make them accessible to the applicationHow do I access these parameters in my application in order to use in the aspx page for the timer control and in the code behind for a method to use
I'm creating a table with some controls and I want to save all control values in every postback. As the controls are just defined after the page_load, I can't solve my problem this way:
object o;
protected void Page_Load(object sender, EventArgs e)
{
o = createObject();
Create_Table();
if (Page.IsPostBack)
Save_Data();
}
I thought I could execute Save_Data() at the begining of every postback event, but I think that should exist a better way to solve my problem.
I have some logic that loops and adds a new Panel control to another control:
for (int segmentIndex = 0; segmentIndex < segments.Length; ++segmentIndex)
{
holder.Controls.Add(new Panel() { Width = Unit.Percentage(segments[segmentIndex] / segmentsSum * 100), CssClass = String.Format("segment segment-{0}", segmentIndex) });
}
container.Controls.Add(holder);
This works great, but there are a few values that I need to store on each panel within the loop. I need to be able to access these values in both c# and javascript, once the control is rendered on the page. What would be the best way to achieve this? I've used the Tag property before on some controls, but a Panel doesn't have one.
I have an ASP page which displays a text box when it loads. It takes an input number, send it to the server through post back, and then displays some record in a grid view. After a number is input into the box, the server fetches some data from a database and add records to the grid view. It also contains a link column, whose URL is set to "#", so that the page isn't redirected when it is clicked.
Now I want to bind a jquery "click" event to that link. How can I do that ? I have tried that to do myself but failed, because it is not available when the DOM is loaded (since it only contains rows when a number is input through the box), and is being modified through ASP.NET Ajax post back.
I have a MasterPage in my project which it contains a FormView and the FormView is databound with a Connection String to a SQL DataBase.
This FormView is selecting users information from Database, when the ContentPage is loading, Im trying to get the information from the FormView of MasterPage and load them in Content Page, but it is not working fine for me.
For Example:
In MasterPage I have a FormView such as follow:
Name: Amir
LastName:Zandi
Username:amirzandi
In ContentPage, I have a Label and I want to get the name from MasterPage and replace it with the text of the Label.
I am doing this at PageLoad of Content Page with the Following Code:
[code]...
At the page load of ContentPage, it says that it could not find the FormView1
but after I refresh the page, it works fine.
is there anyway for me to ask the FormView in MasterPage to DataBind and After that, it retrieves the Data from FormView and place them into the ContentPage.
I also tried: fv.databind() but it is not working.
I currentlly am trying to get a bit value from a specific cell, i can get a text value from text cell but i cant seem to fiqure out how to access the bit value. This is on a dgvRowCommand event so im using datakeys to access the row and a column index for the coloumn like so.
lblFolderRead.Text = dgvCollabFolder.Rows[currentIndex].Cells[1].Text;
This works if im trying to get a text value but obviously a bit value isnt text and thus does not return anything, How would i access a bit value in the manner above, or if it is not possible that way what other alterntives are there?
