How To Focus A Specific Textbox
Dec 19, 2011
I'm making a desktop application in vb.net. When I click the back button (placed by me) on any form it hides current form and shows previous form but when i go again to the form from which i had hit back button then the focus cue still remains on the back button but I want the focus to be on the first textbox on that form or any specific button on which I want.....How can i achieve this...
I have already used some code to shift focus from one textbox to another when i press enter key...but it doesn't work in the above mentioned case....I'm using vb.net in visual studio 2005...This is the code i'm using for shifting focus among textboxes
Private Sub party_code_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles party_code.KeyDown
If e.KeyData = Keys.Return Then
party_name.Focus()
End If
End Sub

I am having problem setting focus on specific cell in my Datagridview1 . On Form1 when clicking on cell 3 in any row, I am callig a Dialog1. However, when done working with it, and closing the Dialog1, the focus returns to cell 3 in my Datagridview1 . I like to set the focus on the next cell(4) making it the current cell.
I have tryed :
DataGridView1.SelectionMode = DataGridViewSelectionMode.CellSelect
DataGridView1.CurrentCell = DataGridView1.Item(4, e.RowIndex)
DataGridView1.CurrentCell = DataGridView1.CurrentRow.Cells(4)
And few other things, I am always getting this exception: Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.

I have a stand alone application that I am writing that has a button to luach a website I am developing.The button checks to see if the website is already open.If it is, the application should set focus to the website in IE8.I am having, is if the website is already open in a tab in a IE8 window, but the focus is on another tab (e.g.url..I can set the focus to the entire IE8 window using the HWND, but not the tab I intend to have focus.Even though they are multiple tabs, they all have the same HWND because they are in the same window.

I have a form with 3 controls that have TabIndex values set:Combo box (cboPostpone) - TabIndex = 0 Postpone Button - TabIndex = 1 Install Now button - TabIndex = 2
The code below is part of the Timer1.Tick event The code below seems to change the focus but then when trying to tab through the controls, it stays on the combo box.
[Code]...
Lastly, I removed cboPostpone.Focus() command from the Timer1.Tick event and move it to the Postpone button Click event. I run the focus command right after the me.hide command. I delayed it the first time and it came back with the Postpone button in focus again instead of the combo box.

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 my project exercising the PrintDocument Control, I want to set the font of one of 5 text boxes, Print location, etc depending upon which textbox has focus. I was hoping to loop through a text box array until the box with focus is found and use a vb6 trick like 'If tb(i).gotfocus then SetFont(i)' but the 'gotfocus' property seems to be missing in vb.net.Although I could use a button click or mousedown event

When the form loads, I query the dataset, and populate the dataGrid with initial values. My problem is that I cannot set the focus to the textbox. I have done the obvious (textfirstname.focus()), in the form loaded event. (and yes, I'm attempting to set the focus AFTER I have dealt with querying and filling my dataGrid).It seems that no matter what I have tried, the cursor always begins in the first row, first column of th

I am entering a values into another textbox and I want it to surrender Focus to another textbox if the value I have entered is the same as the one in the database.However what is happening is that if the value is the same as in the database the cursor just disappears and it does not give focus to the control that I want it to give focus to. Any ideas on how I can correct this.
Private Sub txtProducedAt_TextChanged(sender As System.Object, e As System.EventArgs) Handles txtProducedAt.TextChanged
Dim iSql As String = "SELECT ID,SiteName FROM Sites WHERE SiteName = '" & txtProducedAt.Text & "' "
Dim da As New OleDbDataAdapter(iSql, LoginForm1.Conn)
Dim dTable As DataTable = New DataTable
da.Fill(dTable)
If dTable.Rows.Count = 0 Then
Exit Sub
ElseIf dTable.Rows.Count > 0 Then
txtProducedAt.Text = dTable.Rows(0)("SiteName").ToString
txtAccountNumber.Select()
End If
End Sub
I've tried putting code into the tabindex changed event but its not doing what i want and also in the lostfocus event
Private Sub txtProducedAt_TabIndexChanged(sender As Object, e As System.EventArgs) Handles txtProducedAt.TabIndexChanged
Dim iSql As String = "SELECT ID,SiteName FROM Sites WHERE SiteName = '" & txtProducedAt.Text & "' "

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.

I 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).
I do have a check in the TextBox.leave event that checks for empty values using

I actually want to ask two things, first, how do I set Textbox1 to get focus so that the user will not have to click the textbox if he wants to write something, the .focus() method does not work also, how do I highlight texts inside a textbox programmatically. I think the equivalent code for this in VB 6.0 is Home+End.

i have a window form which has text boxs, buttons and radio buttons.when the form is loaded i want to put the cursor focus to TextboxA. But what i got is it didn't go to textboxA although I call TextboxA.Focus() at Form_Load event.In my Form_Load event() i have:
1) assign a value to a global variable.
2) hide a panel
3) set this TextBoxA.focus.
What i found is if i didn't checked the radio control to True in Form design time, the focus is go to that place, textbox.If i set the radio checked = True in form design time, focus is go to this radio button although i set TextBoxA.focus in form load line end.In my radio_checkedchanged() event, I have:
1) clear all textbox and set the focus to textbox. ( i even tried remove the set textbox focus line in this radio event but it didn't work)
But i must at least set this rdo button checked = true to carry on.if i set true, focus get lost.My program is a simple user registration form. Here is the

VB.NET Windows Forms Project, VS2010.I have a tabcontrol with several tabpages and on each tabpage there is a textbox. I want the focus (and insertion point) to go to the end of the text in the textbox when the tab is selected. If I make a junky project with the following code in each tab, it works fine:
Private Sub TabPage1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles TabPage1.Enter
With TextBox1
.SelectionStart = .Text.Length
.Select()
End With
End Sub
However, the same code is not working in my actual project. I am having trouble debugging, because if I step through, the breakpoints and IDE mean the focus events don't fire in the same order.
