I have several textboxes in a winform, some of them are inside a groupbox. I tried to loop over all textboxes in my form:
For Each c As Control In Me.Controls
If c.GetType Is GetType(TextBox) Then
' Do something

I want to add textboxes in my form as per the input I give. Say, My code will prompt me to enter the no of files I would like to upload... If I give input as "3".... it should generate 3 textboxes to enter the file names....
View 3 Replies[Code] Somewhere my system haves a function that returns a DataSet with the books of a certain subject and all the Authors that wrote such books. I need to show the book's attributes in some textboxes inside a Form. I use a BindingSource to display the ISBN, Name and Subject of the books in a textbox, yet I don't know how to display the author name of the book I am currently viewing in a TextBox, taking into account I already fetched the Author into the DataSet.
Its pretty much the Child/Parent display problem somewhere discussed in the codebank, but kinda backwards, the thing is that I;m navigating through the CHILD records here, not the parent, yet i have all the data needed in my Dataset.
I want to clear all of the text boxes in a groupbox without hard coding them all. I tried the following snippet, but it also clears all of the form labels which I would like to keep.

I have a groupbox with a number of textboxes. I want to loop through all the textboxes, get their value( text) and add them all together and show it in a final totaltextbox outside the groupbox. This is what i have done but it does not work. The totaltextbox values do not change. Here is my code :
Private Sub AGroupBox_VisibleChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles AGroupBox.VisibleChanged
Dim xxx As Integer
[Code].....
I have the following code:
For Each control2 As Control In GroupBox3.Controls
If TypeOf control2 Is TextBox Then
Dim txt2 As TextBox = TryCast(control2, TextBox)
If counter > totalBoxes Then
[Code]...
What I am doing is looping through each textbox in groupbox3. Then checking if the counter(total number of grades that are inputted in the form) are greater than the totalBoxes(which is set to 0) and finally I am putting the actual grade(A,B,C,D) into the textbox. The problem is that it is starting the loop at textbox 8(I have 10 textboxes) for some reason and going from there. Does anyone know what the problem is with my code?
I created a groupbox and then populate it with buttons during runtime. I also created a button, say Button1 to loop through the groupbox and delete those buttons.[code]...
View 2 RepliesI am trying to do an application where several textboxes and buttons will be added to a groupbox.

Im working on a lay-away form application, this particular part is part of the even where the user adds a new customer, and has come to the section for adding personal references to the customers account. What Im trying to do is to check all the text boxes inside the GroupBox control, and then add all the tags of the text boxes that are empty to the list. If the list holds any records it will be put into a message box to let the user know he missed this value. But I want them to list in one text box. Here is what I've tried:[code...]
I get a conversion error, Cannot convert Prompt to String.
I updated a VS2008 vb.net application to VS2010 targeting the .Net 3.5 framework. This application has a windows form that contains a tab control. This tab control contains 6 tab pages. The tab control's tab pages contain group boxes. The group boxes have their anchor property set to Top, Bottom, Left and Right. The tab control's anchor property is also set to Top, Bottom, Left and Right.
When I open this form in VS2010 and resize the form, the tab control is automatically resized. The group boxes inside each tab page appear to automatically resize. If I close the form and immediately reopen it and click through each tab page; the first tab page's group box is resized, but each of the other tab pages's group box has not been resized.
I reported this issue through Microsoft Connect - [URL]. This worked in VS2003, VS2005, VS2008 but was broken in VS2010. I really want the behavior that existed in the previous versions of visual studio. Right now, I have to manually resize each individual group box every time I bring up the form in the designer.
I have a load of information on my label in a groupbox on the form there is too much information to be seen in one go so i want to use a vertical scrollbar to move the label up and down inside the groupbox so it can be read.
The issue i'm having is:
1: The label covers the bottom edge of the groupbox (looks a little naff) i need it to fall inside the groupbox if possible.
2: Any movement on the vertical scrollbar seems to send the label in one direction only - so how do i work it so that up moves it up and down moves it down?
Should i use a multiline textbox rather than a label and move the carat?
Is there a way to select multiple radio buttons within a groupbox. I have a case where I need to disable the mutually exclusive feature.
View 21 RepliesI've been struggling with something I imagined would be simple. My aim is to create a TextBox or Label with in a GroupBox using VB.net, yes I could use the Toolbox/Common Controls to do this easily, but it's a pain when planning on making more than just one or two of them
Here's my current coding to create the actual text box.

All that works perfectly, but how would I allow it to show up within a GroupBox?
i have to create for loop that create each time a new GroupBox with new name and location this is not a homework.it is a personal Application to manage my information [code]i have to change the name of the first Dim in the loop each time , but i couldn't.

[URL] I'm trying to do an exercise on that website but it doesn't show the answers to the exercises..
I've gotten everything to work except one thing. I can't get the right numbers inside the textboxes! I've been sitting here for like an hour trying to use a case statement.. it didn't work for me so I tried to use if then statements and I still couldn't get it to work!
Here's my code for that part:
Ignore the second if I was desperate xD
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
[Code].....
And for the Case statements, if I wanted to use it for a range of numbers, do I write "Case 1 To 10" and that's numbers between 1 and 10? Is that right?
I've got the following issue: I want to make my program change the Backcolor property of all textboxes inside a TabControl. The problem is that one of the Tabs has got another TabControl in it, and I need to change those too.I'd like to to it all at once, but I'm getting an error using this code.
vb.net
For Each SpeechTextBox As TextBox In TabControl.Controls
SpeechTextBox.BackColor = ColorFondoTablasUSE[code].....
The error I get says this:
System.InvalidCastException was unhandled
Message="Unable to cast object of type 'System.Windows.Forms.TabPage' to type 'System.Windows.Forms.TextBox'."
I read somewhere in the forum how to make this work, but I can't find it.
I am using a gridview in my form.aspx page. The textboxes in each row of the gridview are to be populated from a datagrid upon clicking a particular field of the datagrid
View 1 RepliesI need to create text box at a run time.
I found the following VB NET code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim textbox1 As New TextBox
[Code].....
When this row GroupBox1.Controls.Add(textbox1) and GroupBox control are being deleted from Form, the TextBox isn't created on the Form after the event is fired.
This is my first time using WPF. It has been a bit of a nightmare, but I've done enough of the project that I now don't want to start all over again with a forms application.
My problem is this: I have 50 textboxes inside an expander, which in turn is inside a stackpanel. I need to store the value of each textbox in an array. In forms I would probably do it something like this (I am using vb.net by the way):
Dim i As Integer
Dim values() as string
For i = 0 To 49
values(i) = form1.Controls("TextBox" & i).text
Next i
(Assuming my textboxes were named Textbox1, Textbox2, Textbox3 etc.)
How can I do this in WPF? I've tried using Trees (I think they're called?) but have failed every time and now given up.
Oh, I also forgot to mention that there are also other controls in the expander (labels that are paired with the textboxes).
i have a sort of problem when i try to add some linklabels in my groupbox. I used this
Me.Controls.Add(Groupbox3)
Groupbox3.Controls.Add(FlowLayoutPanel)
I can only add 4 linklabels no matter how big is the groupbox, i tried autoscroll but nothing. How can i do to store minimum 20 linklabels in a groupbox? Here is the whole code i used:
Imports System.Net
Imports DevComponents.DotNetBar.Controls
Imports System.Windows.Forms[code]....
Is there any way, maybe with a specific reference to put a control that records what plays wmp activex and to save somewhere on your computer?
Can you add values inside textboxes that are located in tables in Visual Basic 2008?
I put a TableLayoutPanel on a form and inside the Table I put textboxes. Outside the table there is a button. The whole point of the program is so that the user inputs numerical values inside the textboxes and then hits the button and the answer comes out in another textbox. But its not working. It worked when I didn't put my textboxes inside the TableLayoutPanel.[code]...

i know there are no "control arrays" in vb.net. i do come from vb6, and im trying my way now within bv.net, so please be gentel...
if someone could please post a simple code to do the following, it would be great:
i have 3 textboxes called txtBet1, txtBet2 and txtBet3.
i have another 3 texboxes called txtResult1, txtResult2, txtResult3.
so i want to have one loop code, to get the value in txtBet1, calculate somethings, and put it into txtResult1.text.
i know it's basic, but i tried using this sample here as a reference, but its not really understandable for me, because its not really choosing the exact control i want to address...
this is from Microsoft website - a comparison between vb6 and vb.net:
"' Visual Basic 6.0
Private Sub ClearText()
For i = 0 To Text1().UBound
