In VB6, Something.SetFocus sets the focus to that Something. No problems there - in .Net it's called .Focus.On another thread I was told (twice!) to use Something.Select in a particular scenario (which works fine by the way).

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".

I 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.
I'm developing an application in WinForms and I have 2 MDI children and I'd like to know the difference between Form.Focus and Form.BringToFront
I would like to know which one to use when clicking on a respective form's titlebar in order to have it pop up while I'm drag/dropping the form
If you are setting the child form mdiParent property after you are calling Form.Show then it messes up the focus of all the child forms so for me, drag/drop of MDI children inside an MDI parent won't focus the form upon Drag start, but only after MouseUp
When a Windows Forms TextBox control first receives the focus the cursor has to be there at first position in the Textbox.
We have tried to resolve the above issue by adding below code in form load event.
TextBox1.SelectionStart = 0
TextBox1.SelectionLength = 0
Now, when a Windows Forms TextBox control first receives the focus, the default insertion (cursor) within the text box is to the left of any existing text. The user can move the insertion point with the keyboard or the mouse. If the text box loses and then regains the focus, the insertion point will be wherever the user last placed it.
But the problem is when some operation is performed in TextBox_Leave event, it will loose the focus. Again when it receives the focus, the whole text is getting selected instead of showing cursor where the user left.
I need the text within a textbox to be selected when the user clicks in via the mouse, if the user uses the Tab key the text is selected. I have tried Handlers .Enter / .GotFocus / .MouseClick / .MouseUp with textbox1.SelectAll() but it doesn't select the text.

I have a numeric updown. And I was looking for a way to select the numbers when a user gets focus. I know how to do this for a textbox, but there is no SelectionStart/SelectionLength expression.

I'm using the code below to select the text within my textbox during the mousedown event. It works great when the HeaderChanged sub is not called. The problem is, the HeaderChanged sub will always be called on the textbox's focus event.If the user clicks the far right portion of the textbox the whole text value will be selected (like it should), but if the user clicks near the left side of the textbox only a portion of the text will be selected.

View 1 RepliesI 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?
I make the TextBox1 properties become multiline and has vertical scroll. This is my code :

is it possible to have the same effect as a dialogue box, with form focus? eg, when using the open dialogue box, if you try to focus on another form within the app, it doesn't' let you and starts flashing. But when you switch to another app, it doesn't interfere.

When I call the sub window, I want the set the cursor at Textbox1.
The problem is, when I call the window for 1st time, the cursor stops at Textbox1. When I call the window for 2nd or 3rd time, the cursor stops at other textbox or buttons inside the sub window.
Seems like Textbox1.focus is not working.

I 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.
I 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?
I 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()

I 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 RepliesI 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?
I 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.
