View 5 RepliesI am trying to refresh an asp.net page using this command:
<meta http-equiv="Refresh" content="10"/>
On that page I have 2 treeviews. The refresh works ok when I just open the page, but when I click on one of the treeviews and expand it, the refresh stopps working and the page isnt being refreshed. Is there any connection to the treeview being expanded? Here is the full code of the page:

View 2 RepliesI'm looking for a good jQuery or CSS, or combo, library to enance my left side menu in an an intranet application. I don't like the 'hover only' expand/collapse style of the ASP.NET Menu control on its own, and I don't like the 'icon-click only' expand/collapse style of the TreeView control on its own.
I plan on trying the CSS Control Adapters, to render the menu with some self-respect, i.e. as nested <ul> or <ol> elements instead of the usual orgy of tables. Beyond that, I need something to give a bit of style and menulike behaviour to these nested lists, and I would prefer a jQuery plugin for this. Which should I use?
Periodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just
a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.

View 1 RepliesI have a treeview which will be generated dynamically which need to be displayed on left side and when user clicks on a node it need to open a page on the right side of the same page. and each node has different aspx page. so whenever user selects a node the page details should be displayed on the right side .we can use an iframe on the page which will display the different pages clicked on the node.Is there any alternative i can use to display different pages based on the user selection on the right side without using iframe.

We have a web server running IIS 6.0 and ASP.NET MVC, that is serving plain xml. The IVR Browser is not accepting the xml being output by the web server.
The Controller just returns a normal ActionResult, but changes the Content-Type to text/xml.
The View is just a typical aspx page, but instead of html, we've put xml in there instead. When we view this in a browser, it properly returns the xml in the View. In the IVR, it just bombs out. If we remove the Page Directive on the View, then the IVR works.

It is working fine in my local machine but when I deploy on my server then it is not working.is it any iss setting or something else..
what I need to do for this.below is web.config code and local machine having IIS 6.0 and Server having IIS 7.0
I've recently taken an existing ASP.NET 3.5 web forms application that was upgraded to .NET 4 last year (and has been running fine) and configured it to also run ASP.NET MVC3 following Scott Hanselman's blog post: Integrating ASP.NET MVC 3 into existing upgraded ASP.NET 4 Web Forms applications. It works well and I've successfully begun to introduce views based on Razor and the existing aspx pages continue to work.
The one thing that has stopped working, however, is a custom HttpHandler (our load balancer hits a specific address to ensure the application is available - the handler is for that address). The web.config has always declared the handler in the system.web section like this:
<httpHandlers>
<add verb="*" path="system/heartbeat.aspx"
type="My.Monitor.HttpHandlers.LoadBalancerHandler, My.Monitor"/>
</httpHandlers>
Now we're testing post-MVC3 and I'm getting an exception that reads:
The controller for path '/system/heartbeat.aspx' was not found or does not implement IController. I have defined a RegisterRoutes method in my Global.asax and that method is called from the Application_Start. Within RegisterRoutes I've got the IgnoreRoute declarations from Hanselman's blog:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("{resource}.aspx/{*pathInfo}");
which I thought was to prevent the Routing system from taking anything with an extension of .aspx. I can reproduce the issue in VS2010 as I debug, and the deployment environment is running IIS 6. What can I do to prevent the Routing system from trying to handle that address so the custom handler can do it's thing?
I have developed a web application, it is working fine without any issues in IE5 and IE6. However it is not getting executed in IE7 properly. The look of the web application was changed and doesn't look as it need to be in IE7. And one more issue is I will be using PopUp windows in the page. When I try to open the PopUp window they were not getting opened. I have checked if the PopUp blocker was blocked, the pop up blocker settings was Okay.. I have cross checked the code it was fine.

View 2 RepliesI am working on a project currently where I need to get data out of a 3rd party vendor's software that uses a .sdf file I looked this up and its a SQL CE file. I was hoping to just link to with with access but thats apparently not going to happen. I need to link to the database extract data from it to a csv file for later use. I also and most important I need to get the data from it and create a report that can be printed while on a customers site that my or may not have web access so I need for this program to be on and off line. I had my webapplication that I have been working on open and was able to bring up the sdf file under the server exploere however I can't seem to get anything out of it when I try to do grid views or detail views errors out.
Can I use one of Visual Studio projects to create this sort of applicaiton if so what would be the best approach. I would love to get an access odbc driver since office is allready installed on the employee's laptop's
