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?

Lost Focus Event, What Control Is Getting Focus?

Mar 21, 2012

I have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!

So for example something like this...

Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then

LEAVE Event And LOST FOCUS Event When Entering Data

Feb 9, 2011

I have a Visual Basic Program that, when I enter data into a textbox, uses LEAVE events to update it. However, it will not update until I go to another textbox or press a button or other similar control.This also happens when using the LOST FOCUS event.How can I make the textbox update (be it doing a financial recalculation or some other custom function) happen when the user clicks/tabs out of the textbox and NOT having to click on a button or into another textbox?Do you recommend having a separate button for performing the custom functions?

Tool Strip Container Tools Strip Lost Focus And Double Click?

Aug 19, 2011

"Form1" has a ToolStripContainer1.TopToolStripPanel which contains a ToolStrip with buttons. The buttons work on ONE click when "Form1" is active.If I click on another window and then return to "Form1" the ToolStrip buttons take TWO clicks to activate.The first click returns focus to "Form1" and the subsequent click fires the button event.I want the buttons to work on the first click and not require two clicks.Note that ordinary buttons on "Form1" that are not part of the ToolStrip work on the first click when returning from another window/form?

Combo box 2 is filled based on a selection made in combo box 1 and a listview is populated based on the selection made in combo box 2.When the LostFocus event completes in combo box 1, it hits the LostFocus event in Combo Box 2 but it shouldn't.

Forms :: Changing The Backcolor Of A Control When It Has Focus And Lost Focus?

Feb 16, 2011

Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

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.

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.

Lost Focus In Program

Nov 25, 2011

I have a form with 7 textboxes, all describing different attributes of a used car. In the shared leave event of my tb's, I need to code a case statement which determines the particular textbox that lost focus. I then need to perform different tasks which I understand how to do, and I don't think they matter to my question.

I understand how to give focus (txtTextBox.focus()), but how do you tell if something has lost focus?

And furthermore, how would you use that to structure the case statement?

Arrow Keys In MDI Focus Is Lost

Nov 28, 2009

I had previously made a simple Pong program which use keyboard to control. The control includes "s" to start the game, "p" to pause, "r" to resume and left, right to move the paddle specifically. This program work with little problem. The first problem I encounter is if I insert even one single button on the form to display instruction, the arrow keys will no longer work. But I get around it by using Menu Strip instead.

Then, I am required to put this program, among others into a MDI program. And this is where the problem happen. If I have this Pong game loaded, and I press "s", "p", or "r" keys, it have no problem, but if I press the "left" or "right" keys, it will not move. I am speculating that maybe the focus is lost when arrow keys is pressed or something similar, but I have absolutely no idea what is happening. I have tried giving focus back to the form if focus is lost, but to no avails. And this is the code for the movement of the paddle. This reside on a form, the movement itself is passed to another class. The MDI parent is on another form. [Code]

Know My Application Lost Focus In Program?

May 10, 2012

I am using VB.NET to build my application. And in my application has a lot of Forms. It doesn't use MDI Parent Form, but I use another simple Window Form (I named it frmMain) that I suppose it is my MDI Parent Form. When frmMain load, windowState = Maximized. And when I open a Form (example: I named it frmCustomer) that I suppose it is my child Form, and I set its properties (frmCustomer.TopMost=True) when it load, so it always on the top. But When I change to open another application such as Ms. Word or Mozilla Firefox... the frmCustomer is still on the top. how can I know my frmMain lost focus?

Difference In User Clicking The Button OR Calling The Button Click Event Inside The Code?

Aug 23, 2009

I believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.
