I am building my first Hello World Web part using the Cloud 9 videos as tutorial.
I am using an Azure VM with SharePoint 2013, SQL Server 2012 and VS Premium 2013 Update 4.
The Web part is a simple textbox with a button and a label. The click event triggers a method which sets the text of the label to "Hello, " + the text from the textbox.
protected void btnSubmitThis_Click(object sender, EventArgs e)
{
lblOutput.Text = "Hello, " + txtTextBox.Text;
}
I have been able to push my Web part and insert it into my SharePoint 2013 home page.
The click even does nothing at all. Actually, when run in debug, I can see that the constructor, OnInit() and Page_Load() all execute but btnSubmitThis_Click() does not.
The Web part does have an ascx.g.cs file attached.
I can see that this file also includes the code below, showing that the event does handle the method properly:
[global::System.ComponentModel.EditorBrowsableAttribute(global::System.ComponentModel.EditorBrowsableState.Never)]
[GeneratedCodeAttribute("Microsoft.VisualStudio.SharePoint.ProjectExtensions.CodeGenerators.SharePointWebP" +
"artCodeGenerator", "12.0.0.0")]
private global::System.Web.UI.WebControls.Button @__BuildControlbtnSubmitThis() {
global::System.Web.UI.WebControls.Button @__ctrl;
@__ctrl = new global::System.Web.UI.WebControls.Button();
this.btnSubmitThis = @__ctrl;
@__ctrl.ApplyStyleSheetSkin(this.Page);
@__ctrl.ID = "btnSubmitThis";
@__ctrl.Text = "Submit";
@__ctrl.Click -= new System.EventHandler(this.btnSubmitThis_Click);
@__ctrl.Click += new System.EventHandler(this.btnSubmitThis_Click);
return @__ctrl;
}
There are no errors generated that I can see, the click event simply does not call the method.
What could I be missing here?
I am ready to answer any question, as I really would love to figure this one out and I have spent a few days trying on my own, already.
Thanks a lot in advance for your help.

public partial class HelloWorldWebPart : WebPart

// Uncomment the following SecurityPermission attribute only when doing Performance Profiling on a farm solution
// using the Instrumentation method, and then remove the SecurityPermission attribute when the code is ready
// for production. Because the SecurityPermission attribute bypasses the security check for callers of
// your constructor, it's not recommended for production purposes.
// [System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Assert, UnmanagedCode = true)]
public HelloWorldWebPart()
{
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
InitializeControl();
}
protected void Page_Load(object sender, EventArgs e)
{
int Test = 0;
}
protected void btnSubmitThis_Click(object sender, EventArgs e)
{
lblOutput.Text = "Hello, " + txtTextBox.Text;
}
}
}
It did not want to work as a sandboxed solution. Although debugging is harder in a farm solution, it seems to be more robust.
