Is there any ways to create our own RouteData from a URL string in asp.net mvc?
for example I have a URL string like this.
Url: http://localhost/supports/online chat?operator=A
From RouteData, I can find what is controller and action name.
but I have no idea to put it in RouteData.
I have several routes defined in my Global.asax; now, when I'm on a page I need to figure out what is the route name of the current route, because route name drives my site menu. I can't find a way to get current route name.
View 4 RepliesI am building a simple performance logger that hooks in to Application_EndRequest / Application_BeginRequest
I would like to send my logger the name of the action and controller as some sort of key.
How can I access this information? (Don't mind if I have to intercept it earlier on and keep it around in the context)
My web site has a handler (FileDownload.ashx) that deals with all file download requests. I've recently migrated my site to ASP.Net 4.0, and it now uses routing extensively. Everything works fine when dealing with page requests (aspx), but it's not working with my handler - I encounter the following error:
Type '<snip>.Handlers.FileDownload' does not inherit from 'System.Web.UI.Page'.
This makes sense, as routing is only implemented in the page. So, my question is, what steps do I need to take to be able to use routing and my ASHX together? I want to be able to extract RouteData.Values from the url.
public class FileDownload : IHttpHandler
{
}
Although I'm not using routing in an MVC application, this post seems to fit best here :)
I'm trying to access the datatokens that I've passed with the MapPageRoute-method and in a simple Webforms page it works, but in Application_AuthorizeRequest it seems like it's not populated yet.. DataTokens.Count returns 0 although I have passed one item
Is there an alternate way to access the DataTokens? The routing has initialized (it seems), because there's a major difference between url's that is mapped and one that's not..
From the regular Webforms page I'm using Page.RouteData.DataTokens["PagesID"] and in the global.asax file I'm using Request.RequestContext.RouteData.DataTokens["PagesID"]
How I can access the mvc RouteData in the CreateKernel override when using ninject.web.mvc extension and inheriting NinjectHttpApplication?

I am trying to get the ID but its giving me null all the time
I am then binding them in my AJAX
I am using the code below (simplified for this example) to post data to a SharePoint list
StringBuilder customerDoc = new StringBuilder();
customerDoc.Append("<Method ID='1' Cmd='New'>");
customerDoc.Append("<Field Name='Name'>" + Name + "</Field>");
customerDoc.Append("<Field Name='Age'>" + age + "</Field>");
customerDoc.Append("<Field Name='City'>" + city + "</Field>");
customerDoc.Append("<Field Name='Country'>" + country + "</Field>");
customerDoc.Append("</Method>");
XmlDocument xDoc = new XmlDocument();
XmlElement xBatch = xDoc.CreateElement("Batch");
xBatch.SetAttribute("OnError", "Continue");
xBatch.InnerXml = sb_method.ToString();
XmlNode xn_return = sharePoint.listsObj.UpdateListItems(ConfigurationManager.AppSettings["SaveCustomer"].ToString(), xBatch);
As you can see I am using a stringbuilder which isn't ideal so I wonder what I should use instead to create an XML string?
Let's say I wanted to create a user control from a raw string rather than a .ascx file, how would I do that? Temp files are not an option. Is this even possible? I can't find anything online about this.
Bonus: How would I do this with the new razor engine?
How would I create a type while knowing just the name of the type in string form example...
My aspx contains this and some bindable control
<asp:EntityDataSource ID="EntityDataSource1" runat="server"
ConnectionString="name=MyEntities" DefaultContainerName="MyEntities"
EntitySetName="MyData">
</asp:EntityDataSource>
Now from code I need to be able to create an instance of EntitySetName="MyData". Keep in mind I will not know these names until runtime tho. I can do EntityDataSource1.EntitySetName and this gives me the name in string form. But now I need to create and instance of it and get access to the members so I can manipulate the data. I have been trying Activator.CreateInstance and used various overloaded versions of it. Bottom line tho is I am not seeing how to do this. I keep running into trying to cast something into a type when all I have is the name of the type.
I have a few classes: SomeClass1, SomeClass2.
How can I create a new instance of one of these classes by using the class name from a string?
Normally, I would do:
var someClass1 = new SomeClass1();
How can I create this instance from the following:
var className = "SomeClass1";
I am assuming I should use Type.GetType() or something
I am sending a request to a web service which requires a string containing XML, of which I have been giving an XSD.
I've ran xsd.exe and created a class based on this but am unsure of the best way to create the xml string to send, for example a stream, XMLDocument or some form of serialization.
UPDATE
I found this here
public static string XmlSerialize(object o)
{
using (var stringWriter = new StringWriter())
{
var settings = new XmlWriterSettings

which lets me control the tag attribute.
I want to loop through my datatable column called SDESCR and created a string that looks like this.

For Each row As DataRow In tablegraph.Rows
labels = labels " ' " + row.Item("SDESCR") + " ',"

I am currently trying to find a way to convert a string into an asp.net server control.I am storing the asp.net code of Custom Web User Controls in a database and I'm hoping to retrieve this code, convert it to a control and then render the control to the page.The code stored in the database will be asp.net code, not html code. i.e. <asp:Label ID='lbl' runat='server' />

I want to create an Select SQL string by some search fields. Since I can't check the blank ones, otherwize it would look for blank, I have to do this on steps, adding them if they where not in blank, so, for that I am using something like this:
String SearchString = "SELECT * FROM Sala ";
String SelectWhere = "WHERE "; //This where is because I may receive all empty, so, the WHERE would make problems in the string.
If (TextClassroom.Text != "") {
SelectWhere += "(Classroom = " + Classroom.Text + ")";
}
But here is the issue. I may search for more than one at once, and that, would make me have to put an "AND" clause between them. How do I check that in the less number of lines as possible? I made a count variable, so I can count when it has been entered. But, getting to the third time it gets in, I have to check if the number is 1, or the number is 2, to see if I need to put an AND, right? And that would start making hard when we have, like, 10 fields. Is there an easier way to check when to put the AND without that many checks inside checks of empty texts?

When I hover over this link on the rendered page I get a link that looks like "http://xyz.com/products/details/computer+gadget"and the correct product detail is returned after I have url.decoded the string in my Details method.

I know these are unsafe values, but is there a way to work around this safely to allow the strings keep these characters?
