.net - Winforms Textbox Focus With TabControl?
Aug 22, 2011
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.

The only way I found to set the focus on a TextBox inside a TabPage is:
Private Sub Form1_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown
TextBox1.Focus()
End Sub

Does anyone know an easy way to set a keyboard shortcut for a tab in a tab control in Visual Studio 2010? Is there some property I can set?
I looked online, but all the articles I saw were very confusing.

Really wracking my brain here and I'm sure it's something simple I'm missing. Basically I have a form with two tabs. I'm checking the controls on each tab to see if they're dirty and want to prevent a user from clicking a tab if there are changes on the current tab.
I had thought if I check the dirty variable and just set the tab index to the one that hasn't been selected I'd be fine but every time I programatically set a tab's property, it fires off a bunch of the tab's events that just produce an undesireable result such as the right control set is showing but the wrong tab is selected. Here is the code for as close as I've gotten to getting it to work.

I have a created a program that allows the user to select an option button and that button takes them to the correct tab. Ive set all the tabs to visable = false untill the option button has been selected. The problem i am having is setting the focus, so the button sgoes to the tab instead of just making it visable again.

I'm having a weird behaviour with a left-aligned TabControl in VB.NET. Screenshot:
What I wanted was to have the tabs literally the same way they would be if rotated 90 degrees to the left. Does it have something to do with the fact I'm not (god forbid) using the standard XP theme? Any solution to just make it work? (Even if it's hard, but I don't want a control that has a contrasting style, I want the program looking consistent)

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

I would like to show a Form without focus - PLUS - I would like to have 'Enable Application Framework' enabled on the My Project > Application form. Having 'Enable Application Framework' enabled allows trapping of unhandled exceptions project-wide.
I have added this to my code:
Protected Overrides ReadOnly Property ShowWithoutActivation() As Boolean
Get
Return True

I have a custom UserControl that contains just one TextBox. When I set the control to Enabled = False, the TextBox is disabled but the control is not (control still fires the Enter event).
How do I ensure that the UserControl will not receive focus?My Enabled Property Looks like this:
Private _Enabled As Boolean = True
Public Shadows Property Enabled As Boolean
Get
Return _Enabled
End Get

There is a panel which contains 2 components: a label and a TreeView. The hierarchy, obviously, looks like this:panel1 // handles Enter event
- label1
- treeView1
I need to do some UI updates when user starts interacting with any of these 3 controls. My attempted strategy was to catch the Enter event of the panel, which would fire when user clicks a label, or TreeView. This way, I can write only one (1) event handler instead of several. While it worked for the TreeView, it didn't work for the label. When I click the label, I don't get the Enter event on the panel. Whats different about the label control? I could handle the Click event of the label. At the same time, I wonder what the other solutions might be.

I have been using a tabcontrol with multiple tabpages. On one particular tabpage I accept a value into a textbox which has worked many times. For some reason the textbox has now disappeared {clumsy thumbs are always a possibility}. However, when I try to put a new textbox in its place I find the textbox name already exists. I look for the name in the components address box in the properties sections of the ide and it doesn't exist?

how to validate and save the results of a textbox when I change to another tab on a tabcontrol?I have found the SelectedIndexChanged and LostFocus but they do not tell what was the tab that has been previously selected, so I then can do that validation and save. is there an event that triggers before the SelectedIndexChanged?

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.

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.

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

I've tried putting code into the tabindex changed event but its not doing what i want and also in the lostfocus event
