Forms :: Changing The Backcolor Of A Control When It Has Focus And Lost Focus?
Feb 16, 2011Is 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".

Forms :: Form Losing Focus - Keeps Loosing Focus ?
Nov 26, 2009I have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.
The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.
Can't Set Focus On A Windows Forms Textbox?
Jun 9, 2011I can't seem to get input focus on a textbox when a tab page first comes up (I'm using Windows Forms, VB.NET 3.5). I have a textbox on a panel on a tab page, and I want the focus to be on the textbox when the tab page comes up. I want the user to be able to start typing immediately in the focused textbox without having to click on the textbox. I have tab stops set in the order I want and the textbox is the first tab stop. The tab stops work except that when the tab page comes up the focus is not on the textbox, i.e. the one that's first in the tab order.
In the Enter event handler of the tab page I call the Focus method of the text box, but it returns False and does nothing, no error messages. I know I can access the text box because at the same point in the code I can set the text of the text box.If it matters, the layout of the tab page is a little complicated:[URL]..I want to set the focus on TextBox1.
What's the best way to get the focus on the desired textbox? If setting focus is the best way, why is the textbox.Focus() method failing?
Forms :: Difference Between .Focus And .Select?

Forms :: Use The Focus Events Of The Combobox's To Determine?
Jan 7, 2010I have two questions for anyone who can throw some idea's my way question 1:I am currently working on a control with three combo box's. This control will be nested on a form, and I want the on-board timer to track how long each control is active. I am trying to use the focus events of the combobox's to determine if the control is active so the program will know when the timer should be started and stopped. My problem is, for example, when the user causes the text property of the combo boxes to change, the folowing code runs:
[Code]...
As you can see, there are points in this sub-routine that can cause the focus to shift, as well as fire the text changed event. While this all happens faster than is really noticable, I would like to eliminate the extra cycles if at all possible. As I mentioned in question one, I am adding this control to a form, to be more clear I am adding multiple instances of this control to a single form, and I am trying to use the focus events to determine which of the controls within the form are active; however, when the form itself is no longer the active application, whether it is minimized, behind another application or otherwise, all of the timers stop. I want whichever control was active at the time that the form was deactivated, to continue as if nothing changed.
VS 2008 - Working With Two Forms (Focus On Both) At Same Time
Jan 18, 2011I have a form from which I am visually representing data (from access database). I have set up a user log on a separate form (allows user to make comments as they scroll through the data and see any points of interest etc). The second form is linked via a textbox in terms of a common field in this case the field name is "Datetime".
What I want to do is be able to scroll through the data and make notes on the second form and add them to another table in the database. I have managed to do all the above but obviously loose focus of the second form when i scroll through the data on the first. Is there any way of being able to interact with both forms at the same time?
C# - Set Focus To A Deeply Nested Control In Windows Forms?
Jul 19, 2011I have a main form that contains a vertical SplitContainer.Inside the SplitContainer's left panel, I have a TreeView control.Inside the SplitContainer's right panel, I have another SplitContainer (this one horizontal). This container is fixed, with headings above the split and a Panel control below it.I dynamically load my own user controls into the Panel control whenever the tree view changes.
Most of the user controls that are dynamically loaded have a DataGridView that should receive focus when the control is initialized. Sometimes this grid is on the UserControl surface directly; sometimes it's in a GroupBox; etc.What is the best way to programmatically set focus on the DataGridView control, given that it may placed within a variable number of control containers? I've tried the obvious - .Select, .Focus, .ActiveControl, etc. None of these seem to work - the TreeView item that I selected is still highlighted, and even though a record is selected in the DataGridView, it doesn't have focus.
Here's the code where I add the user control within the main form:
Private Sub LoadRightPanel(ByVal section As String, ByVal moduleName As String)
Heading.Text = String.Empty
SuspendLayout()
RightPanel.Controls.Clear()

Forms :: Focus() Method Fails With Second Show Form?
Feb 7, 2010I have a simple login field, which works fine with the exception of one quirk. The form is set up with the tab order to go to the UserID first and the Password text box second. This works fine when the form is used the first time, but when the form is used the second time the focus in placed in the Password field. If the form is used a third time, focus is moved the OK button, that is each time moves to the next tab order. I even tried to set the focus in the Load event as in Me.txtUserID.Focus(), but this doesn't change the behavior. Again, I should note that I close the form and not hide the form.
View 3 RepliesForms :: Base Window Events Are Triggered When Focus Is On Another Form On Its Top?
Apr 3, 2009I am migrating my code from vb.net 1.1 framework to vb.net 3.5In my windows application, the base window has some buttons and events are written for the same.I have shortcuts defined for these buttons also, for example: ctrl+d, DEL (keyboard) etc.Now i open a property Grid form on top of my base window for a selected object.Even when the focus is on this property grid, i am noticing that my base window events are firing on pressing those shortcuts.
example:I select some text in my property grid and hit delete button from keyboard. The delete event that i have written for the selected object gets fired and the text is not deleting.I fail to understand why is it happening. It wasnt behaving like this in .net 1.1.In .net 1.1 it would delete the text and only when the focus is back on the base window, hitting Delete would call the event.How do i control such a behavior? Is there some property that i need to set for property grid in .net 3.5 to prevent base window events from firing till the time focus is on property grid form?
Forms :: Restore A Windows Form Which Is Minimized And Has Lost Focus?
Dec 2, 2009I have created an app which has a timer control which, when activated and meets a certain criteria, launches a second form with an alert for the user to review and action. this works just fine. Except.... when the main app is minimised and has lost focus, instead of launching the second form to a normal windows state it opens and sits in a minimized state itself and just flashes. How can I get the the second form to restore to a normal windows state?I have tried form2.focus and tried the windowsstate=normal etc but I'm still barking up the wrong tree.
View 2 RepliesWindows Forms: Unable To Click To Focus A MaskedTextBox In A Non TopLevel Form
May 20, 2010I've got a Child form being shown with it's TopLevel property set to False and I am unable to click a MaskedTextBox control that it contains (in order to bring focus to it). I can bring focus to it by using TAB on the keyboard though.
The child form contains other regular TextBox controls and these I can click to focus with no problems, although they also exhibit some odd behavior: for example if I've got a value in the Textbox and I try to drag-click from the end of the string to the beginning, nothing happens. In fact I can't use my mouse to move the cursor inside the TextBox's text at all (although they keyboard arrow keys work).I'm not too worried about the odd TextBox behavior, but why can't I activate my MaskedTextBox by clicking on it?
Below is the code that shows the form:
Dim newReportForm As New Form
Dim formName As String
Dim FullTypeName As String
Dim FormInstanceType As Type

View 3 RepliesLost Focus Event, What Control Is Getting Focus?
Mar 21, 2012I 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

Forms :: "Counter" On Form Quits Counting When Form Loses Focus?
Mar 15, 2009Most of my experience in Visual Basic programming is in VBA. I'm currently trying to build a VB.NET Windows application that basically consists of a form that has one button and one label. When the button is clicked, the label should serve as a "counter" that counts from 0 to infinity until the user closes the window with the "x" button. I do this by putting a loop with a sleep statement in the onclick sub. The loop iterates the integer that is displayed in the label and does a "Me.Refresh".The problem is when the window loses focus. When it loses focus (when I click off of it), the counter stops. Even when I click back on it, the counter doesn't resume.

Jan 29, 2012Basically, for my first VB project, I am creating a virtual keyboard where a sound is played from the resources on KeyDown. So far, the program seems to work except for the fact that each key needs to be clicked by the mouse before the sound is played by pressing each key (hence put the object in focus), where I need the key to play the sound without clicking the keyboard key (put the object in focus on KeyDown). Below is an example of my code:
