  • Cannot set textbox value in Callback handler in asp.net

    - by user102533
    I am using ASP.NET Callbacks (that implements the ICallbackEventHandler) and in the handler, I try to set a value of the text box: txtName.text = "Test"; but this value is not set. Is this a limitation with callback? It appears I cannot do much in a callback handler other than sending back a string to the client side (ofcourse I can access the Session etc)

  • authentication winform + asp

    - by user156144
    I am building a desktop application that needs to update current user's status frequently. This status will be available as RSS feed. In order to do this, I think I can create a asp.net folder and secure it using form authentication. When the desktop application written as winform in c# needs to update status, it can set WebRequest.Credentials and upload data. Is there any better way of doing this? Thanks

  • Asp.net web service: Problems accessing without www

    - by MysterM
    I have a Asp.net web service running on www.domain.com/Service.svc that I connect to using jQuery from my asp.net website. Everything works perfect if the user access my website with www.domain.com. But if the user uses only domain.com I get error: There was no channel actively listening at 'http://domain.com/Service.svc/get?date=2010-10-09'. This is often caused by an incorrect address URI. Ensure that the address to which the message is sent matches an address on which a service is listening. In my web.config I use the serviceHostingEnvironment tag to get the service running on my webhost (it doesn't work otherwise). Maybe this is what causes the error? Here is my system.serviceModel in web.config (I had some problems setting up the web service so that's why my web.config might be a bit messy: <system.serviceModel> <behaviors> <endpointBehaviors> <behavior name="ServiceAspNetAjaxBehavior"> <enableWebScript /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="ServiceBehavior"> <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment aspNetCompatibilityEnabled="true"> <baseAddressPrefixFilters> <add prefix="http://www.domain.com"/> </baseAddressPrefixFilters> </serviceHostingEnvironment> <services> <service behaviorConfiguration="ServiceBehavior" name="Service"> <endpoint address="" behaviorConfiguration="ServiceAspNetAjaxBehavior" binding="webHttpBinding" bindingConfiguration="ServiceBinding" contract="Service" /> </service> </services> <bindings> <webHttpBinding> <binding name="ServiceBinding" maxBufferPoolSize="1000000" maxReceivedMessageSize="1000000"> <readerQuotas maxDepth="1000000" maxStringContentLength="1000000" maxArrayLength="1000000" maxBytesPerRead="1000000" maxNameTableCharCount="1000000" /> </binding> </webHttpBinding> </bindings> </system.serviceModel> How can I make it possible for my users to access my webservice also when using only domain.com?

  • Best practice to include log4Net external config file in ASP.NET

    - by Martin Buberl
    I have seen at least two ways to include an external log4net config file in an ASP.NET web application: Having the following attribute in your AssemblyInfo.cs file: [assembly: log4net.Config.XmlConfigurator(ConfigFile = "Log.config", Watch = true)] Calling the XmlConfigurator in the Global.asax.cs: protected void Application_Start() { XmlConfigurator.Configure(new FileInfo("Log.config")); } What would be the best practice to do it?

  • Disable the postback on an <ASP:LinkButton>

    - by y0mbo
    I have an ASP.NET linkbutton control on my form. I would like to use it for javascript on the client side and prevent it from posting back to the server. (I'd like to use the linkbutton control so I can skin it and disable it in some cases, so a straight up tag is not preferred). How do I prevent it from posting back to the server?

  • ASp.NET Dropdown and Dictionary

    - by Lijo
    Hi Team, I am using a dropdown list in ASP.NET with C#. I am trying to bind a dictionary to the dropdownlist. How can we specify the "Text" (key of dictionary as Text of drop down) and "value" (value as Value) for the dropdown? Could you please help? Note: There is a constraint that a class should not be introduced for this purpose. That is why I am trying to use a dictionary. Thanks Lijo
