dynamic ascx user control button event handler not firing – fix

admin — Thu, 17 May 2012 04:34:56 +0000

Remember to assign the control and ID and in the controls Page_Load re-assign that ID

Dim ClinControl As OOClinicianRecord = Page.LoadControl(“~/OO/CareTeam/OOClinicianRecord.ascx”)
ClinControl.ID = “OOClinRecord”
newItemPanel.Controls.Add(ClinControl)

then in OOClinicianRecord.ascx.vb

Private Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load

Me.ID = “OOClinRecord”

End Sub

Add this as your event handler to the code behind (using vb.net in this example)

How to use ASP.NET AjaxControlToolkit

admin — Sun, 18 Dec 2011 05:16:06 +0000

Follow these steps to install the AjaxControlToolkit into your Visual Studio enviroment: http://www.asp.net/ajaxlibrary/act.ashx

Here is an example of the PopupExtender control

Include:
<%@ Register Assembly=”AjaxControlToolkit” Namespace=”AjaxControlToolkit” TagPrefix=”asp” %>

Javascript function to close the pop-up:
function hideajaxpop() {

var bh = $find(“PopEx”);

bh.hidePopup();

}

ASP.NET controls to make the pop-up work:

TargetControlID=”HyperLink1″

PopupControlID=”pnlPatientSignup”

Position=”Bottom” />

Determine what part of your site is actually used

admin — Wed, 26 Oct 2011 19:26:29 +0000

Why put your development effort / dollars into areas of the site / web application no one is using. Or use this to question areas you are developing and verbally ask clients why they don’t use a certain portion of your site, you might find out only a small change makes all the difference in the world to your client.

Google analytics is a great tool to determine where users are going and what they’re doing on your site. On top of the typical usage on seeing which pages get hit, here is the necessary code to see which buttons get clicked or any other event on your site.

——————————————-
Place this in the tag of your page (use your correct Account ID, the rest will stay the same)

——————————————-
Place this in the hyperlink or button’s onclick event (ClickDescHere is what will show up in Google Analytics), if you have multiple subdomains like we have Google even breaks down the click events for you by hostname.

onclick=”_gaq.push(['_trackEvent', 'ClickDescHere']);”

PHP / MySQL – Upload a file to access later

admin — Wed, 01 Jun 2011 14:33:19 +0000

In this example I am uploading to the file system, but saving the location in mySQL to reference later.

————————————————————–

//Database variables are located with-in here
include(“dataconnection.php”);

$con = mysql_connect($hostname, $username, $password);
if (!$con)
{ die(‘Could not connect: ‘); }

$selected = mysql_select_db($dbname);

//Generate Random Number & date to add to file name so they’re always unique
$rNumb=rand();
$today = getdate();
$id=$today['mon'].$today['mday'].$today['year'].” “.$rNumb;
$id2=str_replace(” “,”",$id);

//Move temp file auto created to permanent location
$uploadfile = ‘uploadfiles/’ . $id2 . basename($_FILES['fileupload']['name']);
if (move_uploaded_file($_FILES['fileupload']['tmp_name'], $uploadfile)) { }
else {}

//Check to see if anything was uploaded, otherwise set variable to nothing
if($uploadfile == ‘uploadfiles/’ . $id2)
{$uploadfile = “”;}

if (!mysql_query($sql,$con))
{ die(‘There was an issue, please go back and try again, if it still happens please contact technical support’); }

mysql_close($con)
?>

PHP – handling apostrophes

admin — Wed, 01 Jun 2011 14:22:53 +0000

Here is the code you’ll need to use to handle apostrophes, this just adds a backslash in front of the apostrophes

$myvariable = str_replace(“‘”,”\’”,$myvariable);

Emailing from PHP

admin — Wed, 01 Jun 2011 14:18:33 +0000

about 98% of the time your web host will already have the php.ini file set up correctly so literally all it takes to email is this (if that’s not the case look here: http://www.php.net/manual/en/ref.mail.php#77499)

//Send Emails

$emailmessage = “Body of your message goes here, I put it in a variable because it’s usually very long.”;

mail($_POST[email], “Email Subject”, $emailmessage , “From: no@no.com” . “\r\n” .”bcc: lucas.baran@figers.com”);

SQL findtext – create a stored proc to find text in other stored procs

This stored proc has come in handy many times, great to use it to find text in other stored procedures
