In my MVC application I use HandleErrorAttribute to display a custom error page in case of unhandled exceptions, and it works perfectly unless the exception happens in an action called by Ajax.ActionLink. In this case nothing happens. Is it possible to use HandleErrorAttribute to update the target element with the contents of an "Error.ascx" partial view?
View 2 RepliesI would like to make a custom accordion, in which I have 2 panes, but where you couldn't open the second one until you clicked a validation button in the first one that would open the second...
I tried to just make a button that would hide the first pane but I cant get to make it work.

View 2 RepliesI have been trying to make a program work with our IIS server, but it's run into a tricky problem that's been driving me nuts. When I debug the program, everything works perfectly; users are able to log in and they see the appropriate content according to the user's role. When logging in from a remote location, however, the program seems to have trouble finding the users' roles. Users can log in, but they cannot see any role-specific information, so they are stuck on the login page forever.
I tried adding a line of code to find the roles of a particular user. In debug mode, it returned the roles correctly, but when accessed through the server, it returned an empty array that caused my site to crash.
i have a text box, on text_changed event i get one data table which i bind with the grid view, but every time i have to move the cursor out then only it feteches the datatable, while i want to make this search like if i as i change the character in the text box it keep working for all without removing the cursor from the text box, how can i achieve this. Should i use any java script or what.
View 2 RepliesI have a page with a listview that shows something like posts. On each post there should be a "rate box" which works similar to the "Like" button in facebook. The rate box is a User Control, that has an update panel inside it.
If I put the control with some random values in the page it works great - but when I put it inside the ListView, where it should be located, it won't work. The method is being called, but nothing happens.
I simplified the code a bit to make it easier to understand:
[Code]....
While debugging I noticed the controls in the method "OnRateClick" are empty and don't contain the right values.
I am trying to add validation on my form. I am using AJAX controls in my form fields.
When I remove the Update panel and AJAX control, my validation starts working, but when keeping both the things together, my validation is not working. How could I make them work together?
<script type="text/javascript">
function Validate() {
var QuestionTextArea = document.getElementById("ctl00_ctl00_cphBody_midbox_fvInsert_txtQuestion");
varError = "";
if (!IsTextBoxEmpty(QuestionTextArea, "
Question Text Area not be Empty.")) {
alert(varError);
document.getElementById("ctl00_ctl00_cphBody_midbox_fvInsert_txtQuestion").focus();
return false;
} return true;
}
</script>
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<asp:TextBox ID="txtQuestion" runat="server" MaxLength="1000" Columns="50" Rows="5" Style="width: 380px;
float: none" Text='<%# Bind("Description") %>' TextMode="MultiLine" />

When I removes ajax extender and Update Panel. My textbox gets validated and when using UpdatePanel. No javascript function created by me is called.

I can't make this control work, the code i'm using to test it is:

So the buttons are not showing, I could add them manually but then a postback would occour on everyclick.
I have a parent web application and a child web application. I am using single sign on between them. The child application is supposed to redirect anonymous users to the login page of the parent application We just updated both to .net 4.0 framework and now the SSO doesn't work anymore.The setup is as follows. I have the machineKey tag all set up with validation key and decryption key in both applications.then, for authentication tag i have the following in the child app (I have replaced the actual parent app's url with "parentApp" for privacy):

I have a user control which encapsulates a NumericUpDownExtender. This UserControl implements the interface ICallbackEventHandler, because I want that when a user changes the value of the textbox associated a custom event to be raised in the server. By the other hand each time an async postback is done I shoe a message of loading and disable the whole screen. This works perfect when something is changed in for example an UpdatePanel through this lines of code:
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(
function (sender, args) {
var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior');
modalPopupBehavior.show();
}
);
The UserControl is placed inside a detailsview which is inside an UpdatePanel in an aspx. When the custom event is raised I want another textbox in the aspx to change its value. So far, When I click on the UpDownExtender, it goes correctly to the server and raises the custom event, and the new value of the textbox is assigned in the server. but it is not changed in the browser.
I suspect that the problem is the callback, since I have the same architecture for a UserControl with an AutoCompleteExtender which implement IPostbackEventHandler and it works. Any clues how can I solve this here to make the UpDownNumericExtender user control to work like the AutComplete one? This is the code of the user control and the parent:

}
registerControl(this.HFNumericUpDown.ClientID, currentInstanceNumber);

// If this function is not written the callback to get the disponibilidadCliente doesn't work

and to create the loading view I use this: //The beginRequest event is raised before the processing of an asynchronous postback starts and the postback is sent to the server. You can use this event to call custom script to set a request header or to start an animation that notifies the user that the postback is being processed.
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(
function (sender, args) {
var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior');
modalPopupBehavior.show();
}
);
//The endRequest event is raised after an asynchronous postback is finished and control has been returned to the browser. You can use this event to provide a notification to users or to log errors.
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(
function (sender, arg) {
var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior');
modalPopupBehavior.hide();
}
);

View 2 RepliesI just finished programming a web application, and I want to upload it to a host server so that it works online. However, I faced some problems.When recalling functions from class files, server can't approach them, and the following error appears: (BC30002: Type 'db_class' is not defined)I know that there are steps I have to do in this stage in order to make the project working. I want your help letting me know what these steps are!
I have reviewed many references and posts in this forum, but I couldn't reach a solution.I built a small project that contains ( default.aspx, app_code/class1.vp and web.config). It would survive my graduation project if you would downloading the project and fix the error appearing, and return me back the modified code.

I am trying to put a basic Hello World Web Service in my Go Daddy Shared hosting.
It is a basic default Hello World Web Service that Visual Studio 2010 automatically generates: it works in my local web machine: i can invoke and can see the xml.
I have transferred the Service1.asmx and the Service1.cs file( in the App_Code folder ). I can view the web service page, but I cannot invoke the web service method, and as a result I cannot see the xml file where the "Hello World" string will be in side the <string> element.
Though I can see the web service page, there is no invoke button. How will I invoke or render the content in an aspx page? As the web page has to change the name space, I have changed the namespace to my website address, but still I cannot see or do an invocation and as a result cannot see the generated xml. My question is
1) what should I do so that I can see the return xml value from the web service?
2) what should I do so that I can render the data of the web service in a web page ( for example, in mywebservicepage.aspx)?

I'm using the technique described on this link to make all TextBoxes on the site highlighted when focused. Basically, in the Page_Load event of the MasterPage I set the onFocus and onBlur attributes for every TextBox found on the current page:
[Code]....
Everything worked fine until I decided to add the UpdatePanel on one page which is used for frequent data entry. Now, when the page loads initially everything is ok, but after the first asynchronus postback is made, controls inside the UpdatePanel seem to loose their onBlur and onFocus efects (controls outside the UpdatePanel are still working fine). I'm not in the best "relations" with AJAX and javascript :)
