Detect Click Event For Programmatically Added Control?

Apr 10, 2011

I do a lot of programming in VS 2010 on my Windows XP Pro PC. Recently I tried testing my software on a Windows 7 Home PC. For some reason, all of the controls on my forms are slightly misplaced. I also get a bunch of unhandled exceptions I don't get on my pc. For example, one exception said it couldn't access a registry key. Another said it couldn't find the part of a path (it didnt specify which path). What's up? Why is it doing this? My Win XP PC tricks me into thinking my apps are bug free. Guess not.

Control Array - Add New Event - Click Event Code And Calling It A Doubleclick Event

Jul 31, 2010

I'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 ...

Detect Button Click Before Lost Focus Event?

Jan 30, 2010

My application has a form which contains several Textboxes where user is required to fill up data. Once data is filled up user can click on "Save" button to save the data. I have added lost focus events to all textboxes so as to validate user input. When I click on cancel button, i want to detect cancel button click, but textbox lost focus is fired first so I get error message for textbox before my code moves to cancel button click handler. Is there any way to detect button click before lost focus event?

Event Not Firing On Dynamically Added Control

Nov 19, 2010

I'm adding multiple combobox controls to a form dynamically, but am having a problem with one of the event handlers. The first event handler I've added (for the Leave event) fires, but the second (for the TextChanged event) does not. I've tried reversing the order when adding the handlers and I get the same results (TextChanged does not fire). Here's a code snippet for adding the controls, and the code for the events. I've added a breakpoint while testing to verify - but it never hits the code.

Dim cbo As New ComboBox
cbo.Name = "cbo" & fldName
cbo.Tag = fldName.ToUpper
cbo.Top = rowtop
cbo.TabIndex = tabOrder
cbo.DropDownStyle = ComboBoxStyle.DropDown

Detect Control Click In Form?

Jan 26, 2009

Ok before I get flamed hear me out. I have a form with panels containing tablelayoutpanels containing various amounts of controls that alternate visibility. On the form in its entirety I am looking at roughly 3200 controls most of which are radio buttons.

Now that being said, I am trying to figure out a way to capture what control (mainly radiobutton) is being clicked on through the forms events. So far my attempts have failed with mousedown, mouseclick, etc. Yes I know I can use the "handles radiobutton1.Clicked" event directly. However with that many radiobuttons....I know that there has to be a better way to do this. An API, windows hook, something. So far my efforts to find an alternative method have failed.

Active X Control - Click Event - User Has To Double-click On Button In Flash Movie

Mar 23, 2009

I have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.

Asp.net - Building A Server Control That Inherits Button And Giveing It Other Click Capabilities - Catch The Click Event?

Dec 1, 2010

I want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:

Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)

My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.

Responding To A WPF Click Event In A Data-bound User Control?

Oct 15, 2009

I have created several WPF User Controls. The lowest level item is 'PostItNote.xaml'. Next, I have a 'NotesGroup.xaml' file that has an ItemsControl bound to a List of PostItNotes. Above that, I have a 'ProgrammerControl.xaml' file. Each ProgrammerControl has a grid with four different NotesGroup user controls on it (and each NotesGroup contains 0-many PostItNotes.

Then, I have my main window. It also has an ItemsControl, bound to a list of Programmers.

So, you end up with a high level visual view of a list of programmers, each programmer has four groups of tickets, each group of tickets has many PostItNotes.

The trouble I'm having, is that I want to respond to a mouse click event in my mainWindow's code behind file.

I can add a MouseClick event into my PostItNote.xaml.vb file and that is getting called when the user clicks a PostItNote, and I can re-raise the event; but I can't seem to get the NotesGroup to listen for that event. I'm not sure if that's even the correct approach.

When the user clicks the PostItNote, I'm going to do a bunch of business-logic type stuff that the PostItNote control doesn't have a reference to/doesn't know about it.
