C# - Execute ClientSide Before ServerSide?

Aug 5, 2010

I am using ASP.NET 3.5.

When the user click on say btnSubmit I want to first execute some JavaScript code and then execute some C#/VB.NET code.

Is this possible? If so how would one do it?

Web Forms :: Need To Know (the Value Of A) Clientside Property On The Serverside?

Aug 23, 2010

I need to know on the serverside, if a RadioButton has been disabled (by javascript) on the clientside.

The (serverside) Enabled property is not the same as the (clientside) disabled property. Using MyRadioButton.Attributes("disabled") doesn't do the trick either.

C# Trying To Serialize An Enum Type Serverside And Then Output It In Clientside JavaScript

Jun 18, 2010

Let's say I have a function that takes a string. That string contains the fully name of an enum type (e.g. "MyCompany.Area.AotherNamespace.MyEnum").

How could I create an array of strings (or List<string>) whose elements are the values of MyCompany.Area.AotherNamespace.MyEnum?

Is that even possible?I'm basically trying to serialize an enum type serverside and then output it in clientside JavaScript so I don't have to define an enum in two places--in my C# and my JavaScript.

Web Forms :: RequiredFieldValidator Works Clientside With Javascript... But Doesn't Validate Serverside With J?

Mar 12, 2010

I'm making a website in ASP.NET 4.0 where I make use of the RequiredFieldValidator control to validate a wizardstep.It works perfectly with Javascript enabled, but when I turn it off (in my Firefox) it just goes to the next step.We don't do a Page.IsValid check, but we don't do much on the "next button clicked" event either.Certainly not something that is forcing it to go to the next step.

How To Execute Serverside Code In Parallel With Client Side Code

Aug 2, 2010

I have a web app that needs to do two things at the same time. After a user clicks a button on the site, a javascript function needs to execute and while thats working I need the server side code for the button click to execute without waiting on the client side to finish.

To be more specific, the client side function takes about 23 seconds to complete, and while that is running the server side code promts the user for printing a document. So I need the javascript to run "in the background".

AJAX :: Execute Animation On An Asp Button That Has To Execute Code On Postback?

Feb 15, 2011

I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.

SQL Server :: Stored Procedure - EXECUTE And EXECUTE Sp_executesql

Mar 10, 2011

I am looking through a sql stored procedure which I might need to update in the near future. Basically the stored procedure is about 20 lines long. The stored procedure first builds a query

and stores it in a variable named "@Sql". And then for the last two lines of the stored procedure it appears that the big sql statement stored in "@Sql" is executed by using the "EXEC" command. See below. What is confusing though is that the query appears to be exectuted twice? Why was the query written in this way. Don't both lines do the same thing? Why is it being done twice? Could this possibly be a mistake on the
part of the person who wrote the query. Below are the two lines I am talking about?

EXEC sp_executesql @sql
EXEC (@sql)

WCF - How To Execute Server.Execute Asynchronously

Mar 30, 2010

I need to run the HttpContext.Current.Server.Execute method in my ASP.NET application. This application has a WCF operation that does some processing. Currently, I am to do my processing correctly from within my WCF operation. However, I would like to do this asynchronously.

In an error to attempt this asynchronously, I tried running Server.Execute in the DoWork event handler of a BackgroundWorker. Unfortunately, this throws an error that says

"object reference not set to an instance of an object" The HttpContext element is not null. I checked that. It is some property nested in the HttpContext object that appears to be null. However, I have not been able to identify why this won't work. It happens as soon as I move the processing to the BackgroundWorker thread.
My question is, how can I asynchronously execute the Server.Execute method?

Web Forms :: How Does .NET Track Things Clientside

Jun 4, 2010

I'm curious, anyone know the mechanism a checkbox control uses to remember that its checked or not checked after a postback?If I add them manually to a page via html as in <input type="checkbox"/> I have to use javascript and hiddenfields to keep things checked after a postback and I would have to have an onclick="dosomething()" inside the tags.Viewing the html source code for a page with a .NET checkbox control, there is nothing like that there.

I was writing a custom control and rendered my own checkboxes when I came across this problem. After the postback, the control would reload the checkboxes from viewstate and forget the user had clicked anything. As I couldn't use hiddenfields to track the changes (they got reset from viewstate too), I ended up using .NET checkboxes as childcontrols instead but this experience got me thinking.

SQLcommand Serverside For Gridview?

Mar 17, 2010

I have a gridview, where I have made autocode using the wizard. However I need a dynamic SQLcommand from server side. I have tried this code, but it doesn't work, it works if I use this code from HTML (setting the sqlcommand in the SQLDataSource. I have deleted the sqlcommand from the HTML and instead I have implemented the code in the page_load event:

Code:

Dim str As String = SqlDataSource1.SelectCommand = "SELECT DISTINCT Beregning.bId, Informationer.Dato,Beregning.bType, Informationer.pNavn, Informationer.pNr, Informationer.Beskr, Beregning.uId FROM Beregning CROSS JOIN Informationer WHERE (Beregning.UserId = @UserId) AND Beregning.uId = Informationer.uId AND (Beregning.bType=@berType2) ORDER BY Beregning.bId DESC"
SqlDataSource1.SelectCommand = str But this code works, when I apply the SQLCommand in HTML:

Code:

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:IsoPlusConnectionStringDrift %>" SelectCommand='SELECT DISTINCT Beregning.bId, Informationer.Dato,Beregning.bType, Informationer.pNavn, Informationer.pNr, Informationer.Beskr, Beregning.uId FROM Beregning CROSS JOIN Informationer WHERE (Beregning.UserId = @UserId) AND Beregning.uId = Informationer.uId AND (Beregning.bType=@berType) ORDER BY Beregning.bId DESC'>
<SelectParameters>
<asp:SessionParameter Name="UserId" SessionField="userId" />
<asp:Parameter DefaultValue="Optimering" Name="berType" />
<asp:Parameter DefaultValue="Kapacitet" Name="berType2" />
<asp:Parameter DefaultValue="Varmetab - Alle rørtyper" Name="berType3" />

Web Forms :: EnableClientScript - Only Clientside If True Or Both Client And Server?

Nov 18, 2010

subject says it all...... when using the various validation controls like requiredFieldValidator, and EnableClientScript is true (the default), does that mean that the only validation is done client side? or does it mean that it is done client side in addition to server side?

I know if the only validation is done client side, like with javascript, it can easily be circumvented. I want to make sure my validation is done serverside, so do I need to set EnableClientScript to false?

VS 2008 Using Clientside Js In Onclick Alongside Validation Controls?

I tried adding a separate onclientclick javascript method to do some extra validation but it now appears to only run this and not continue on to run through the Validation controls. The extra javascript method is returning true, so I'm not sure if the onclientclick is clobbering the scripts from the Validation controls. Can anyone explain what I've done wrong?
