Refresh Page Isn't Working Using Treeview

May 30, 2010

I 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:

public partial class Results : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
// Function that moves reviewed yellow card to reviewed tree

ycReviewedTree.PopulateNodesFromClient = false;
ycReviewedTree.Nodes[ycReviewedTree.Nodes.Count - 1].ChildNodes.Add(ycActiveTree.SelectedNode.Parent);
Application["reviewedTree"] = new ArrayList();
int count = ((ArrayList)Application["activeTree"]).Count;
// Move all the nodes from activeTree application to reviewedTree application
for (int i = 0; Application["activeTree"] != null && i < count; i++)
{
((ArrayList)Application["reviewedTree"]).Add(((ArrayList)Application["activeTree"])[i]);
((ArrayList)Application["activeTree"]).RemoveAt(0);
}
}
protected void ycActiveTree_TreeNodePopulate(object sender, TreeNodeEventArgs e)
{
if (Application["idList"] != null && e.Node.Depth == 0)
{
string[] words = ((String)Application["idList"]).Split(' '); // Yellow Card details
TreeNode child = new TreeNode("");
// Go over all the yellow card details and populate the treeview
for (int i = 1; i < words.Length; i++)
{
child.SelectAction = TreeNodeSelectAction.None;
// Same yellow card
if (words[i] != "*")
{
// End of details and start of point ip's
if (words[i] == "$")
{
// Add the yellow card node

Which JQuery/css Menu Library For Working With TreeView Or Menu Controls

May 2, 2010

I'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?

Web Forms :: Handling TreeView Error Detected By System.Web.UI.WebControls.TreeView.LoadPostData?

Mar 1, 2011

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.

Message: Input string was not in a correct format.

Stack Trace:

IVR Application On Nortel MPS 500 Not Working With MVC

Jan 21, 2010

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.

HttpHandler Not Working In MVC3 Web Application

Apr 1, 2011

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?

Web Forms :: Application Is Working Fine In IE6 But Not IE 7 And Above?

Mar 30, 2010

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.

Aug 20, 2010

I 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.
