In one view (view1) there is a text box and a button beside it. i click on that button, i am popping another view (Create view) as a seperate window. in create view i am entering some values and creating a record in db. out of these values one value i have to send back to "View1". how can i send this value? i am opening view2 from view1 like
<input type="button" value="Get ID"
onclick="window.open('<%=Url.Action("Create","Controller1") %>',
'','scrollbars=yes,width=800,height=800,resizable=yes');"
/>
View2 contains some fields like Name,Email etc... and I click "Create" to call HTTPPOST. there i add the values to db including a generated guid. i want to send this ID to view1.

The page I'm editing had three tabs, each tab contains a diffrent grid view which is populated by a search box with in the tab. Each row in the grid view has a check box. When a print button is pressed all records with a tick in the check box should be printed off. Then page then reloads but some of the content is missing due to the way the page has been coded. This is becuase some of the code is only called when the tab is clicked not on postback. Is there anyway that I change the following code so that it's called after postback? These are the functions that are causing the most problem.. I need them to be loaded for the correct tab on postback.. I can't do it for all three as the code takes forever to run in that case.
AddActionsToGridView(gvGlobal);
AddCheckboxesToGridView(gvGlobal);
{
if (tabconConsignments.ActiveTabIndex == 0)
{
dtGlobalIDConsignments = fGenerateTableSQL(astrPalletIDs, DateFrom, DateTo, ddlReqColDel.SelectedValue, "GlobalID", "", "");
//Global ID Tab
gvGlobal.DataSource = dtGlobalIDConsignments;
gvGlobal.DataBind();
//Actions
AddActionsToGridView(gvGlobal);
AddCheckboxesToGridView(gvGlobal);
}
else if (tabconConsignments.ActiveTabIndex == 1)
{
dtCreatedDateConsignments = fGenerateTableSQL(astrPalletIDs, DateFrom, DateTo, ddlReqColDel.SelectedValue, "CreatedDate", "", "");
//Created Date Tab
gvCreationDate.DataSource = dtCreatedDateConsignments;
gvCreationDate.DataBind();
tbCreationDateSearch.Text = "";
//Actions
AddActionsToGridView(gvCreationDate);
AddCheckboxesToGridView(gvCreationDate);
}
else if (tabconConsignments.ActiveTabIndex == 2)
{
dtAccountsConsignments = fGenerateTableSQL(astrPalletIDs, DateFrom, DateTo, ddlReqColDel.SelectedValue, "Account", "", "");
//Account Tab
gvAccount.DataSource = dtAccountsConsignments;
gvAccount.DataBind();
AddActionsToGridView(gvAccount);
AddCheckboxesToGridView(gvAccount);
}
if you want me to post any more code or any more info it's been a hard one for me to get my head around so I might of missed something out.

I have a simple ASP.NET web application for data collecting (a webform with two text fields and a Telerik editor, a button for submit with server side OnClick event listener attached).The event listener saves data on DB and then redirects to another page.Under development web server the application works fine.When published under IIS7 the event listener doesn't fire. The only way i found to make it work is to specify the action on the form tag:
<form id="form1" action="default.aspx" runat="server">
This is the first time this happens to me, i never run into this problem before with other applications (even more complex!).

I would like to create one view for my CRUD actions. The view contains 3 basic DIV updatetargets ("search form", "search result listing" and "action" (would be create,detail,edit,delete). Basic flow would be: "Search" updates the "Search Result Listing", click on CRUD actions in listing would show partial view in "action".
how do I call to refresh the "Listing" after I do any add/update/delete without having user click search again?
Index:

I have a javascript library and in there i have a method that is called from my view. Here it is:
<li><a href="javascript:void 0" onclick="deleteAll('image', '<%= ViewData["FileGroupId"]%>')"><div><%=GetGlobalResourceObject("default", "Delete_all") %></div><div></div></a></li>
and here is my js code in the javascript library:
var deleteAll = function(module, groupId) {
jConfirm(_deleteConfirmAll, _deleteAll, function(r) {
if (r) {
showProgress();
$.ajax({
cache: false,
type: "POST",
url: _baseUrl + "/" + module + "/deleteall/" + groupId,
success: function(msg) {
if (msg == '0') {
location.href = _baseUrl + '/' + module;
}
else {
jAlert(msg, _errorTitle);
}
hideProgress();
}
});
}
});
}
My problem is that i cant reach my controller. Here is my controller code:
#region common methods
List<.CMS.Core.File> GetList(int groupId)
{
List<CMS.Core.File> list = new List<CMS.Core.File>();
CMS.Core.FileFilter filter = new CMS.Core.FileFilter();
filter.GroupId = groupId;
int res = CMS.Core.File.Search(_connection, filter, ref list);
return list;
}
#endregion
public ActionResult DeleteAll(int groupId)
{
List<CMS.Core.File> list = GetList(groupId);
foreach (File item in list)
{
item.Delete();
}
return Json(list);
}
And at last her is my Index method
public ActionResult Index(int? id)
{
if (Request.IsAjaxRequest())
{
JsonPaging paging = new JsonPaging();
int offset = 0;
int page = 0;
if (!String.IsNullOrEmpty(Request.QueryString["page"]))
{
Int32.TryParse(Request.QueryString["page"], out page);
}
if (page > 0)
{
offset = (page * paging.PageSize) - paging.PageSize;
}
FileFilter filter = new FileFilter();
filter.Deleted = false;
filter.MaxRecords = paging.PageSize;
filter.Offset = offset;
if (!String.IsNullOrEmpty(Request.QueryString["keywords"]))
{
filter.FilterType = FilterTypes.AND;
filter.Name = Request.QueryString["keywords"].ToString();
}
if (!String.IsNullOrEmpty(Request.QueryString["sort"]))
{
filter.OrderBy = Request.QueryString["sort"].ToString();
if (!String.IsNullOrEmpty(Request.QueryString["direction"]))
{
filter.OrderBy = filter.OrderBy + " " + Request.QueryString["direction"].ToString();
}
}
if (id > 0)
{
filter.GroupId = id.Value;
}
List<CMS.Core.File> items = new List<CMS.Core.File>();
int results = CMS.Core.File.Search(_connection, filter, ref items);
foreach (CMS.Core.File current in items)
{
JsonItem item = new JsonItem();
item.Id = current.Id;
item.Name = current.Name;
item.ImageText = current.ImageText;
item.Aperture = current.Aperture;
item.TakenOn = current.TakenOn;
item.Camera = current.Camera;
item.ExposureTime = current.ExposureTime;
item.FocalLenght = current.FocalLenght;
item.Tags = current.Tags;
item.Url = current.Url;
item["Active"] = current.Active.ToString();
item["Created"] = current.Created.ToString();
paging.Items.Add(item);
}
return Json(paging, JsonRequestBehavior.AllowGet);
}
else
{
ViewData["FileGroupId"] = id;
return View();
}
}

I have a simple controller that sends a model/data to a View:
[Code]....
The View displays the data in a HTML Table:
[Code]....
This View displays the data correctly and provides a RadioButton for each row. When I select one of the RadioButtons the previous selection is removed as expected.
For now I am using an ActionLink to enter another Controller action. I have tried many ways without success to retrieve the selected RadioButton's value in this controller action.
[Code]....
I have also tried defining the Controller action with a parameter matching the model without success.

i just want to be able to call a javascritp subroutine on the client, after the server has done its thing (when an action completes or control goes to the view, i'd dont mind calling the js from the view either).
for some reason, even vs2010 doesn't let me put breakpoints in <% ... %> tagged areas between <script...> and </script> tagged areas. i for this reason can't figure out whats going on and how it's running things. here is what i've put in my view, and the javascritp should run, but it doesn't....
im just trying to call "RunOnceRoutines;" but it's not getting called!
the 2 questions: how on earth do we call javascript methods from server, and where is all this lovely javascript debugging i've heard about since vs2008? no where to be found!

Since a Controller Action and its View are associated with each other I would think that there would be a way to delete both in one step.

Is it possible to edit the content of a view from a action filter.
What I am working on is a Resourcemanager that I can use to manage
my style sheets, js and other resources. I want to be able to put
lines in the the view any where like Html.ResourceManager.AddScriptFile("MyScript")
or Html.ResourceManager.AddCSSFile("MyCSS")
and at the end of the view call Html.Render(); this would then place the content of my resources at this point. My problem is that I want to put the CSS stuff at the top of the view, but them problem is that it is renderend at the end of the view, so I tought that I could use a ActionFilter to move it to the top of the view.
1) What would be the best way to do this task ?
2) Is there any resources that describe the way that the MVC framework works in more detail ?

ia ma working on an asp.net mvc 2 app and i have a Users view, displaying all the users of the database. Then, i would like to add the ablility to display "users starting with fisrt name" capabaility on the same view. For this i created a list of all english leters that actually are links (<a href="#">A</a>, etc...)
I managed to handle the click event of each one of the letters and get the corresponding letter via jquery, but i don't know how to call theHttp.Post Users/FindUserByFirstLetterName(string letter) on the click event.
I cannot use the Html.ActionLink<> helper, since it redirects me to the HttpGet controller action.
I also tried using using jqery.Post but i also couldn't manage to call the action.

I am trying to send json data from view to controller action. But the issue is the data is not populating in the action parameter List<Score>.
View Model:
public class Score
{
public int QuestionId { get; set; }
public int PrevAnswerId { get; set; }
public int CurrAnswerId { get; set; }
public string CurrAnswerName { get; set; }
}
Json Data look like:
[
{QuestionId:1, PrevAnswerId:3, CurrAnswerId:3, CurrAnswerName:'Known to Broker'},
{QuestionId:2, PrevAnswerId:7, CurrAnswerId:7, CurrAnswerName:'Completed'},
{QuestionId:3, PrevAnswerId:10, CurrAnswerId:10, CurrAnswerName:'Report'}
]
On window load, I will construct the Json object using "eval()" function and do some operation in the data before its save. On Save Click, I will call the action through the ajax call.
$.ajax({
url: url,
type: "GET",
dataType: 'json',
data: {score: ScoreJson},
contentType: "application/json; charset=utf-8",
success: function () {
alert("succes");
},
error: function () {
alert("error...");
} });
Action:
public ActionResult SaveScore(List<Score> score)
{
// do something...
}
But here score comming as collection of 3 elements with zero(for interger property)/null(for string property) values. When I checked in the request I found the data in "parama" property like.
"Score%5b0%5d%5bQuestionId%5d=1 &Score%5b0%5d%5bPrevAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerName%5d=Known+to+broker&
Score%5b1%5d%5bQuestionId%5d=2 &Score%5b1%5d%5bPrevAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerName%5d=Completed&
Score%5b2%5d%5bQuestionId%5d=3 &Score%5b2%5d%5bPrevAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerName%5d=Travelers+Report&".
But I am not sure why it is not getting populated in the score list. One full day I spent for this issue but till now I didnt find the solution for this issue.

I'm trying to do an Ajax delete in a fairly standard Index few, i.e. I have a generated Index view with one added filter drop-down, of little relevance here. I have changed the free Delete Html.ActionLink on every row to an Ajax.ActionLink, and the delete and ajax update work, but whichever container div I try and update, I always somehow get some kind of nesting in the updated page, e.g. after a delete and update, I get duplicate Home and About links from the master page inside my content. Here is my current action link that causes what I describe above:
<%: Ajax.ActionLink("Delete", "Delete", new { id = item.InstallationDBNumber }, new AjaxOptions { UpdateTargetId = "jobList" }) %>
... and here is where jobList is located, just outside the table used for the index list:
<div style="clear: both;">
</div>
<div id="jobList" class="index-list">
<table>

I have a view that renders a few partial views. Each partial view contains a link that calls an action via ajax. The result from the action is used to fill a div. Because I use the same partial view a few times, it always renders the div with the same id. In asp.net, we have something like naming container, that assures that each element has unique ID. How can I make IDs in a partial view unique ?
