I am trying to do something like:I have a cicle (For Each) which goes trough some items (existing N items)So, for each item read i have to create a control (a Label in this case) which must have the Click, MouseEnter and MouseLeave events . Each event will use/edit properties of the created control Creating those labels is easy but adding the event handler to the control i have no clue how to do it ... Believe me when I say I've spent a lot of time thinking about this .
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 ...
How should I go about getting my mouse position over multiple controls, and such. I can't use the form_mouse move event, or any other control event nor can I use them all at the same time cause that would conflict with the actual position I need for an object.

I 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."
i 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.

Is the code to display/hide an ASP.NET control when a user clicks a button usually done with JavaScript or ASP.NET code? By display/hide, I mean within the page not a popup window.
I have an event which handles multiple controls. How can I tell which control caused the event? [code] I want to run validation on each control, (combo and textboxes) and if it succeeds, enable a button. I could do this for every control individually but I want to know if I can use the sender value to determine which control needs to be validated.
With the tab control, I cannot find the event which is triggered when I first click on a tab The following event is triggered, once on the tab, by clicking on the tab page (not the tab)[code]
Is it possible to handle a mouseDown event in VB.Net (2008) regardless of the control firing the mouseDown event? Basically, I just want to catch a mouseDown event at the "form level" and don't want to program mouseDown event handlers in every control. Is there a way to do this?

I create a dynamic number of PictureBox controls. I keep them inside a List. What I want now is to make them clickable: same event handler for all (opening of the image source file) with a parameter. The question is: how can I do it in practice? How I set the handler Sub for every picbox?
I have some different controls (PictureBox, Label,Button...) that are created by code. The set number of these controls isnot fixed. So let me set this number ton. And I have the following lines of code to create some of these controls.
For i5 As Integer = 0 To n dBoxArray(i5) = New PictureBox 'PictureBox Panel1.Controls.Add(dBoxArray(i5))
I'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? :)
just now I was trying to capture the F1 key on the form, but only managed when the form is selected, and I need to detect it in any form control. I used this code:
Select Case e.KeyCode Case Keys.F1 MsgBox("Right") e.Handled = True End Select
How can I get the SelectionStart value for a control in the Form_KeyPress event?
Form1.KeyPreview = True Form1.KeyPress Dim X as Integer = ActiveControl.Selection {gives error} Dim X as Integer = TextBox1.SelectionStart {this works OK BUT will only work for one control because it is hardwired to TextBox1}
