I've been struggling for some time now with an MVC routing issue, but I have finally reached a point where the basic routing is correct; that is, the application is invoking the correct action method and .aspx page, but the action method fails because no parameters are passed to it.
Before I show detailed screenshots of the problem, I had better provide some background. This is a bibliographic application which, among other things, analyzes text abstracts to identify unique words and the number of occurrences for each word in each document. This data will eventually be inserted into a SQL Server database, but for the time being I only want to do the calculation and display the results, on a document-by-document basis, in an .ASPX view set up for the purpose. The data structure of the application is as follows:
Collections -this is a set of fifty or so CollectionDetails items.CollectionDetails represent individual documents, in this case books in an academic library. Attributes of the CollectionDetail record are those typical of a library book--author, call number, title, year, and so on. The title and subject catalog headings are combined to form a quasi-abstract, which becomes the basis of the text analysis. In a few cases, I added additional text from Google Books or Amazon synopses and reviews.
MasterStopList contains common words such as pronouns and prepositions that we want to exclude from consideration.
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 Tabcontainer with 3 tabpanels. I want to load some content to the different tabs the first time they are clicked (selecting the tabs). I have tried using Protected Sub TabContainer1_ActiveTabChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TabContainer1.ActiveTabChanged but that only works, WHEN there has been changes to the content.
So my question is: How do I raise a server side event like loading a droplist when the tab is clicked?
I have a LinkButton inside a GridView (via an TemplateField). No matter what I try, the LinkButton will not invoke its event handler. I have tried both traditional event handler ("OnClick")A OnRowCommand event handler at the GridView level.In both cases, I've debugged and it doesn't even catch the event handler.
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton Text="Cancel" ID="DeleteButton" CausesValidation="false" OnClick="CancelThis" runat="server" />

I have a user control that contains a repeater. We have added some paging and sorting into the user control and it all works well.
What I need now is a nice way to catch the OnItemDataBound event of the inner repeater and then bubble it up to be accessible directly from the user control from within the page.
We have tried catching it and then declaring it in the user control but it just won't work.
my dropdown list contains 3 items google,yahoo,hotmail.
It the user selects google msgbox should be raised saying "You hae selected google". Thats it. I m not getting how to do that. I tried on selectedchangeindex event but nothing happened.
I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?

I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?
View 1 RepliesI'm working on a wizard-like set of page, and I'm relying on cross page postbacks to navigate between them.
I need to be able to trigger the Load event on the previous page in order to save the form data for the page.
I've been told that for situations of this sort all I had to do is access the PreviousPage property in the destination page and this would trigger the load event of the previous page but for some reason this doesn't seem to be working.
Is there anything else I can do to explicitly trigger the load event on the previouspage if the PreviousPage property is not null?

View 1 RepliesIs there any way for one user control to raise an event that is handled by another user control without going through the page? I am using Umbraco and do not have access to the page object.
--Edit--
Umbraco has the idea of Macro's (user controls) that it loads into pages. I can't access the page directly as this is part of the framework.
There is a publish subscribe (pubsub) pattern that I know would fit my needs well (2 user controls that need to talk to each other) but am unsure how to hook it up in ASP.Net without the page object.

OK, apparently related questions dont seem to address this directly. An exception reaches Elmah, maybe a repository cant reach a database, but then neither can Elmah reach that database. Even if they target different servers, maybe its a network problem.
Is there a way to configure fallback logs for Elmah for cases like this, e.g. a text file, message queue, email, sms, etc? If so, where do I start looking to do this, excpt for now the Elmah source code.
I am using an instance of DirectoryInfo to browse and retrive the files and some file attributes on a physical directory. This is displayed in a html table. But if you have for example text files (.txt) or word dokuments (.docx) How can I display the correct icon that is associated with the file in my html table? And further on how can I reach the user who modified the file the last time? Where is that info saved?
Is the DirectoryInfo the object I should use for this purpose? or are there other objects or functions that I should looking at?
