Can I call executeQueryAsync twice?

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :SharePoint
 
I wanted to know if this was feasible before I spend more time on it. Lets say you have a js method that calls context.executeQueryAsync at the end of it. In its success paramters, can I list another js method and at the end of that again call context.executeQueryAsync? I am getting some errors but thought I'd first ask if this was even doable. In Summary function A(){ var context = new SP.ClientContext(); // set CAMLQuery and get the Next Number Value for item creation in function B context.load(listitemwithnextnumber); context.executeQueryAsync(B, failureMethod); } function B(){ var context = new SP.ClientContext(); // get Next Number from listitemwithnextnumber(this works!) // updatenextNumber // createlistitem context.load(updatenextNumber); context.load(createlistitem); context.executeQueryAsync(successMethod, failureMethod); }

call JavaScript - jQuery code from ASP.NET Server-Side

  
jQuery got so close to me lately that I can see myself adding the scripts to my project almost unconsciously. The thing is, jQuery is very useful for me, in almost all situations and it has been a do or die enhancement for all my project since I first put my hands on it.

Of course while using it, you encounter few situations which need a bit of research to solve, mostly when you are trying to combine it with some other technologies like: UpdatePanels and ASP.NET Ajax. For instance there are many situations when I would like to run some jQuery magic based on some decision that I make on the server side.

Call SQL Stored Procedure Asyncronously

  

Hello,

I have a C# web page that calls a stored procedure. The page passes few parameters to the stored procedure and call it. The stored procedure does so many time consuming tasks on a huge number of database records but does not return any value.

Since the page is not expecting any return from the stored procedure, I want to execute the stored procedure asyncronously so that the user can continue working on the web page and other web pages while the stored procedure is running in the background. Also, I do not want the web server processes to be busy with the running stored procedure.

Any help, please.


Best regards,

Imran

Linq2Sql error: "Invalid attempt to call Read when reader is closed."

  

I've read up on this error from other posts and on other sites, but haven't found a solid resolution to the issue yet. My setup is as follows:

I have a RepositoryBase class that fields certain db calls that all repositories need to perform. In one such call, "GetSecurityGroup", it works most of the time, but will seemingly at random throw an exception with the error "Invalid attempt to call Read when reader is closed." All other Repository classes inherit from this one, and they all use the same DataContext object, which I understand isn't thread safe. Since there could be multiple calls to the DataContext object on the same page, perhaps one is using the DataContext when the next tries to do so. I'm not sure. What can I do to ensure this doesn't happen?

$.ajax post from asp.net page and __viewstate causing call to fail

  

Hello

Now I know that I won't be sending viewstate and eventvalidation in my ajax calls and that I will only want to send the actual form fields for efficiency purposes but I will need to know the answer to this question, to inform the more junior members of the team and my manager, so if anyone has any answers they are most welcome.

I have a simple form as follows

<form id="form1" runat="server"> 
<p>Field1: <

make json call to send an email

  

the aspx:

<div class="contactSubmit">
                <asp:ImageButton ID="ibSubmit" runat="server" ValidationGroup="vgContact" /></div>


 

the jquery :

$(document).ready(function () {
            // Add the page method call as an onclick handler for the div.
            $(".contactSubmit").click(function () {
                $.ajax({
                    type: "POST",
                    url: "Home.aspx/GetDate",
                    data: "{}",
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function (msg) {
                        // Replace the div's content with the page method's return.
                        $(".contactSubmit").text(msg.d);
                    }
                });
            });
        });


The problem is that I need to use the text in a text box in my webmethod, and I can't because it's static, this results in a compilation error:

[WebMethod]
    public static string SendContactForm()
    {
        Mail.SendMailMessage(NameTextBox.Text);
    }
