View 3 Repliesfirstly i am not really an ASP.Net developer but i do work in C#.
Anyway one of the application that i develop has an ASP.Net section and i need to amend it.
I want to add a Checkbox which when Checked by the User will set a Session variable.
This Session variable will then be accessed on another page where it will include/disclude some SQL and therefore change the behaviour of a Search.
So i have 2 Pages - Page1 that has the Checkbox on it -
HTML

1, How do i stop the whole page from executing again when doing a postback ? I only want the Changed Event to run not the whole page
I have a web application where I want to stop any malicious JS to execute.
For example:
http://www.mywebsite.com/default.aspx?ID=<script>alert("hello")</script>
If a client does the above then an alert box pops up on the client screen. How to stop that.?
Also I have set validateRequest="true" in the machine.config but still the JS does get execute.
I want to create my own naming convention for page events rather than AutoEventWireUp but I couldn't find Component Initialize methods any where ? Should I override it ? But in which class it is defined ?
Edit :
For example : I don't want to use Page_Load but LoadThisPage naming. So It should be like
Load += new LoadThisPage(sender,e);
I was expecting a InitializeComponent method where I can initialize page,controls etc. events handlers...But it turned out to be Constructor function :
So what confused me is I thought there should have been a method like InitializeComponent which does things for me already created by Designer itself so I thought I could define my own event handler names within this method by overriding it in the say Default.aspx.cs .
if I am running a detailsView_Deleting code and a condition is not met and I want to Cancel the delete, how do I code it?
View 4 RepliesI have a site that uses ActiveRecord. I'm getting an exception that says "An ActiveRecord class () was used but the framework seems not properly initialized. Did you forget about ActiveRecordStarter.Initialize() ?" This is a web application, and the Initialize() method is called by the Application_Start event handler.
I created a new page that also calls the initialize() method. If I visit that page once, then the rest of the site works. If I visit it a second time, I get an exception stating that the Initialize() method can only be called once.
I've tried modifying the web.config and resetting the application pool to force Application_Start to run.
This only happens in production; dev, my stage, and client stage are fine. Production is the only load-balanced environment--I'm not sure if that comes into play.
Edit: We have another site deployed in the same environment which successfully uses ActiveRecord with the same initialization code. One difference is that the site that is working has only the ActiveRecord code in Application_Start; the site that doesn't also sets up some URL routing in Application_Start.
I have a WCF service that processes some input arguments and retuns result in approximately 4 minutes. Sometimes the calling client may get request time out before the WCF service answers.
Now, my customer is asking me to stop processing on the service side when the client got timed out. Since, I could not know the status of cleint on the service, I could not stop the process.
I'm overriding the Controller.Initialize method to set some stuff before each ActionResult is executed, however I'm finding that the method is being called multiple times for each request (anywhere between 2 - 10 times). I'm running in Cassini.
My hunch is that it is running for all static files (images, css etc) as well as the requested action - although I may be wrong? I thought maybe something was wrong in my web.config but it all looks right to me.
In my company app they are doing the following. I do not understand that what initialize does? Do we need to Initialize assemblies before using them? and what kind of assemblies needs to be initialized?

I have a page with several asp buttons defined on a Master Page. I only wish these buttons to be activated when they are selected by the mouse click. I have one button on the content of the form, that is the button I want to execute if the user hits enter and it is selected or they use the mouse. So in a nutshell. how do I stop the buttons on the master page from executing unless the user mouses them?

I have a button that has click event in my C#. This works great. However afetr pressing F5 to refresh the page I noticed the button event is fired. This occurs every time I click F5. I've added if(page.IsPostBack) and the method still runs.
Is there any way to stop method from firing when the F5 Refresh button is clicked?
I want to execute a CS Code but before that, i want a confirmation from user, it will be a javascript confirmation box, if the user say yes, then execute the code, or else leave cs code don't execute

I'm using the following code in an attempt to show a dialog with a list of errors on the client:
if (rollout.ImportErrors.Count > 0)
{
ClientScript.RegisterClientScriptBlock(GetType(), "showErrors", "showErrors();", true);
}
The error count is non-zero and the following script block is emitted, but the script isn't executing.
<script type="text/javascript">
//<![CDATA[
$("#error-report").dialog("open")//]]>
</script>
If I call the function directly from a Firebug console window, the dialog shows properly, so I know the dialog and my code are working. BTW, this code is in a content page, using a content placeholder that 'injects' code into the element of the rendered page.

I then decided to run the whole thing on the server it uses the same code above but I now have several parameters to pass in and call a slightly different stored procedure
DataSet dsEx = new DataSet();
SqlCommand testcommand = new SqlCommand();
testcommand.CommandText = "spLockUnlock";
testcommand.CommandType = CommandType.StoredProcedure;
testcommand.Connection = sqlLockUnConn;
testcommand.Connection.Open();
testcommand.Parameters.Add("@OffState", SqlDbType.Varchar);
testcommand.Parameters["@OffState"].Value = ViewState["OffState"].ToString();
testcommand.Parameters.Add("User",SqlDbType.Int);
testcommand.Parameters["@User"].Value = lblUserID.Text;
testcommand.ExecuteNonQuery();
testcommand.Connection.Close();
rest of the code follows
The stored procedure uses the parameters to lock certain records, then I use exec spOfflineSystem which executes a series of select statements (as above), then I unlock the records afterwards....no problems however my dialog box on the front now reads
CustomersEC45TG.xml
If you step through the code the filename reads Customers.xml yet on the front end we get the spurious characters....each time this is executed the spurious characters are different. Only every now and then will the correct filename dialog box show.
Here is what I need to do: I need to execute some server side code after a user clicks on a button, THEN I need to execute some client side code. OnClientClick gets invoked BEFORE the onClick; and what I need is the opposite.
Is there a way to do this? It looks like I will have to execute JS code from the server code.
I have a dropdownlist (drpClients) bound to an object datasource (odsProgramClients). In the dropdown's databound event, I load a dynamic table based on the selected item in the dropdownlist. This all works well. However, if I force a problem in odsProgramClients select method, it continues to the databound event of the dropdown and attempts to load the table, even though dropdownlists underlying select method failed. I wish to stop the databound event from firing if there is a problem in the select method. I have code that traps the error in odsProgramClients select method.

How do I stop the dropdownlist from databinding, if there is an error in it's underlying datasource?
