Control Array - Add New Event - Click Event Code And Calling It A Doubleclick Event
Jul 31, 2010I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...
Code:
Imports System
Imports System.Windows.Forms
Public Class form1

View 3 RepliesCall A Control Event From Within Another?
Nov 21, 2011I have a menu item in a program that I'm working on called "mnuFileSave" The Click event goes through several "housekeeping" functions and calls the correct "Save" function.
Another menu item performs a function and depending on the results may want to call the "mnuFileSave".
I have tried RaiseEvents mnuFileSave.Click and get the error "mnuFileSave' is not an event of 'The_Entertainment_Collection.frmCollectionBook'
I have tried Call mnuFileSave.Click an get the error "Public Event Click(sender As Object, e As System.EventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event."
Control Creates Another Same Event?
Sep 29, 2010i already finish this module but while doing 2nd module i notice that my 1st module doesnt work anymore, then i checked my code, i double click the control at design time and thats it instead it brings me to my actual code of that control, it brings me to another event, like this, this is where my original codes are placed:
Code: Private Sub lblSupplier_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub then, after the poblem occurs, the control created another event like this:
Code:Private Sub lblSupplier_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub notice the difference, they are the same click event but the other one has an "_1" at the end of click.

Custom Event In User Control
May 10, 2011I've got a page (aspx) that contains a usercontrol (ascx).On postback of the aspx, I'd like to read some control values in the ascx. So upon reading some good articles, I created an event in my aspx that fires on postback.The event handler is in the ascx, and simply writes the values I'm interested in to the viewstate so that the parent page can read them.The problem is my event handler never gets hit, even though I see the event is raised as I step through the code. So my code bombs when trying to read the viewstate (which is empty)[code]Oh, did I happen to mention I'm dynamically loading the ascx? :)
