I have in the master page an overridden method for OnCommand method.Can I call it programmatically through any page uses the master page?I mean something like the following:
I have code, where i add ImageButton to table programaticly and I need to assign event handler to this ImageButton. When I write ASP/HTML code, there is attribute OnCommand, but in C#, there is nothing like this. Just CommandName and CommandAttribute.
on the code page I have mapped the OnCommand event to the following code
Code:
Protected Sub ImageButton_Command(ByVal sender As Object, _ ByVal e As System.Web.UI.WebControls.CommandEventArgs) Try Dim img As ImageButton = CType(sender, ImageButton) img.BorderStyle = BorderStyle.Ridge SortOrder = e.CommandArgument BindData() Catch exc As Exception ProcessModuleLoadException(Me, exc) End Try End Sub
My problem is that by clicking on the image button in the gridview header, the OnCommand event is not being fired. I have tried this with both OnClick and OnCommand and neither fires. I can't see what I am doing wrong if anything.
I've got a button inside the gridview that isn't firing the onCommand, ONLY when I uncomment some seemingly unrelated code having to do with session in the page load.
Markup:
[Code]....
Code Behind:
[Code]....
Now here is the odd thing. If I comment out the If Not Session block in the page_load....it works and deleteUser will fire upon a button click. If I leave it uncommented as now.....it won't work.
The weird part is when I step through the code in debug, upon clicking the remove button, it still registers that as being clicked and runs page_load, etc again. But won't run deleteUser.
How to call Synchronous service call for combo boxes? As I know Synchronous calls do not create a good user experience because the application is hung waiting for the Web service call to return. Then it is my requirement.
I have an ActiveX object which extends some functions. I have a web page that loads the ActiveX object and calls its methods in Javascript. The ActiveX object has two method; the problem is that Javascript can successfully call one of them but fails to call the other; citing Object doesn't support this property or method which is nonsense because I made a VB6.0 application that successfully calls this other method, so the two functions are indeed extended correctly and performing their job. And yes, the Internet Explorer security zones are all set and everything, as I wrote above the javascript code can call one method but refuses to call the other.
XP Pro,aspnet 2, IIS, Oracle I have a primary webpage that displays a tab and some summary data. The tab uses an iframe and the summary data is loaded by an async WebMethod call back to C#. The iframe page takes a short while to load depending on how much data is in there (sometimes upto 20 seconds?). The WebMethod call, or at least the content of it, is very fast. BUT, the WebMethod call won't return until basically the iframe has finished loading.
I've verified through Fiddler that the browser is initiating both requests at basically the same time. It's initiating the iframe call first followed immediately by the WebMethod call within the same second. My understanding is that browsers are limited to only two calls at once.
If I set a breakpoint at the end of my WebMethod call (even commenting out ALL it's guts so it just returns an empty string), that breakpoint won't fire until the aspnet page serving up the iframe has finished. Using threads window, I see both calls at the server. I just don't understand why the server won't actually run the Webmethod call until the first call has finished. I've searched the code looking Monitor.Enter, lock, etc to make sure nobody has inserted any other type of blocking code and I can't find anything. I've basically emptied out the WebMethod call and it just returns a string, but no matter what I do, it just won't return as fast as it can. If I comment out the iframe, then the WebMethod call returns within 2 seconds. With the iframe, it "looks" like the the webmethod call won't return until the iframe has finished.
1) Does aspnet only process one request per aspnet session id? Is it FIFO? I figured the webserver would just process requests and return each request as fast as it can.
2) What else can I do to get that summary data to return faster (but not actually loading and putting the data into the very first primary page) ?

I am currently moving into the web-hosting league. I have to far been adding sites manually in the IIS Manager. But I wonder if there exists an interface, framework or something similair to manage the IIS over the internet - eg. an ASP.NET web-application? I've read something with WMI, but I am unsure if this is the right path to go? I need to add, edit and delete sites in the IIS Manager on a Windows 2008 server running IIS 7.0 programmatically.
A page could have an attribute MasterType to make Page.Master to be strong-typed:
<%@ MasterType VirtualPath="~/Site.master" %>
If all my pages inherits specific class inherited System.Web.UI.Page itself, can I someway get access to this.Master property in it so I could call master page's methods?
how can i map a network driver programmatically from my asp.net (vb) and download files from the maped driver? is there any code sample anybody can provide me
I am trying to write a quote generator. For each product, there are a set of options. I want to dynamically add a drop down list for each option, and then have their SelectedIndexChanged events all wired up to update the quote cost.
I am not having any trouble adding the DropDownList controls to my UpdatePanel, but I can't seem to wire up the events.
After the page loads, the drop downs are there, with their data, but changing them does not call the SelectedIndexChanged event handler, nor does the QuoteUpdatePanel update. I have something like this:
Edit: Since programmatically adding AsyncPostBackTrigger controls is not supported, I've change my code to this, but I still don't get the event:
Edit 2: Tried adding a PlaceHolder to add the drop down lists to (instead directly into the ContentTemplateContainer, still no events firing.
How to programatically set a:visited and a:hover programatically? I am dynamically building up some hyperlinks server side and want to know how to specify unique css behaviour for each link. Otherwise I would set them all in a stylesheet.
I'm interested in using ELMAH but need to configure it programmatically. We have existing infrastructure for determining connection strings and the like, and can't code them into Web.Config.How do I go about using ELMAH in this case?
