I 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?
We have an interactive windows based application written in VB .Net 2010. It uses Word Object to display documents in MS Word. We have a form with a button. When the button is clicked we open the Word document and maximize the Word Windowstate. When we have the Visual Studio Tool running, the Word Document is maximized and has focus, even if we are running the exe from the bin folder outside of the tool. However, if Visual Studio is not running and we run the exe, focus remains on the original form window and the document stays in the task bar.
View 5 RepliesIs 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.

Basically, I have a form with about 15 text boxes. Most are in different tab pages. By default, text boxes allow anybody to copy and paste by using keyboard shortcuts.I added a tool strip up top and make the "Cut", "Copy", and "Paste" buttons. What I want to do is make them work for whichever text box was last focused. So if I click the Cut button on the tool strip, it will cut the text of the
last text box that was focused.
Example:I open the program and type in TextBox1. Then I type in TextBox2. I want to copy the contents of the last text box by using the Copy key at the top, so I click that and it copies TextBox2 as it was the last focused textbox.
Like I said, I'm not fully sure how possible this is as I do have many. The whole reason I have the tool strip is for users that prefer using a mouse for everything rather than keyboard shortcuts.

I am writing a control in WPF that draws a shape on a form and then draws dimensions of this shape. These dimensions are editable so they are shown in a text box. When the user changes a dimension in a text box the shape is updated. I am updating the shape when the textbox showing the dimension loses focus i.e. as soon as the text box loses the focus the shape and all the dimensions are redrawn.
A text box loses focus in one of two ways - either when user presses tab key or when user clicks in another control outside the text box. My problem is that when user presses tab key or clicks somewhere else outside the text box the whole control is redrawn and the focus is not set to the next control where it should be. This is really annoying because tabs stop working altogether and to set a focus using mouse the user has to click twice.
An image of my control is shown below

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).

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 have simple application that basically allows you to open up and view PDF files.I use an OpenFileDialog control to select the PDF file and a WebBrowser control to view the file (via the Acrobat ActiveX). Everything works great. However, I would like to also record info, from each PDF file that gets viewed, into a TextBox control (someone would read a line or two from the PDF file and type a summary into a TextBox control). Once the PDF file gets loaded, it takes the focus. But instead, I would like the focus to move the TextBox control. Changing the focus upon the Web Browser1_ DocumentCompleted event does not work (I don't believe the WebBrowser control is aware of the PDF itself, just the ActiveX control) In fact, the only way to move focus to the TextBox, after the PDF file is loaded, is to click the TextBox with the mouse. I can't �TAB into that field.
View 9 RepliesI have a Windows Form Application that has a few TextBoxes, Buttons, and a couple of ListViews. One of the TextBoxes takes an entry (usually by a barcode scanner or the user can type text and hit the TAB character) and then that searches through some data structures and if found it modifies the color on a row in one of the ListViews and adds a row to the other ListView. What I want to be able to do is to put the focus back on the Textbox that takes the input from the barcode reader.The problem I'm having is that the TextBox doesn't always get focus back after a scan. Sometimes after a scan it looks like the focus is on one of the splitContainers. I can manually take the mouse and put the focus back on the TextBox, but that would be kind of inconvienient for the user. What I would like would be for the user to be able to scan (which enters text into the textbox and then TABS out). The TextBox's Leave Event fires and runs the code that manipulates the ListView's and then at the end the leave event code clears the textbox with TextBox1.Text = "" and then calls TextBox1.Focus()
I've tried using TextBox1.Select() and/or TextBox1.Focus() and neither one works. I even put in a Apllication.doEvents() so that any pending action that might cause focus to change will happen before I call the Focus() or Select() code.My guess is that maybe it has to do with some race condition on actions that pull focus away, but how can I keep focus on the text field and still allow the user to use the mouse to press the EXIT or SAVE buttons or even click on an item in one of the ListViews (which doesn't do anything right now).
