I have 53 text boxes in my windows forms application. I need to save the "text" of all the textboxes into a single file. Is there a way, I can control all the textboxes as a single textbox group and use its properties.
For example: Can I write something like :
For i As Integer = 0 to 52
Textboxgroup.text = TextBox(i).Text
Next
??
I am writing an application and I do not know how to reference a group of controls inside a group box. I will include the code I have written so far and a picture with a detailed explanation as to what I am trying to do. Feel free to comment on any discrepancies that you may notice in my code.
Code:
Public Class Form1
' The following class-level constants are used
' to calculate the price of the model
Const decCOUPE As Decimal = 18000

The object browser in visual studio contains many controls and properties ....so is it possible to remember in mind all these controls. Whenever i am programming in vb 2008 and for reference i look at the examples on internet i always find some new controls,properties etc which makes me confuse.So i was wondering If by any means there is a way to remember all these controls
View 4 RepliesIn our IDE, for example, Visual Studio, if we display the properties of a System.Windows.Forms.Button control, we see some properties that expose anoter set of properties. For example: FlatAppearance, Font, Location, Margin, etcetera.I would like to do something similar in a custom control.I know the code behind is wrong, but here is an example of what I´m trying to do:
Public Class StateOfMyCustomControl
Public Enum EnumVisibility
Visible
[code]....
In my IDE, in the properties window of my custom control, I would like to see my property State, with the possibility of display it to set the properties Visibility and EventManagement.
I want to do a class that have properties like font, which will have other properties, such as name, size, unit,bold.
<TypeConverter(GetType(ExpandableObjectConverter))> _
Class TestingClass
'Some property here
End Class
I spent a lot of time on this problem. I am able to do simple Group By LINQ queries (on one property) but for multiple fields I'm a little stuck... Here is a LINQPad sample of what I want to do :
dim lFinal={new with {.Year=2010, .Month=6, .Value1=0, .Value2=0},
new with {.Year=2010, .Month=6, .Value1=2, .Value2=1},
new with {.Year=2010, .Month=7, .Value1=3, .Value2=4},

How can I add controls to a form in code and set the properties of the controls using the With statement?Also I would like to know how to add a container control and then add a control to that container.

How can I group controls in my Form?
I don't need groupbox or panels, just something in the code...
To make it clear:
I have one form, Form1.
I have 3 buttons: Button1, Button2 and Button3, and I have 2 labels, named Label1 and Label2.
I have 2 "groups", in group1 there is Button1, Button2 and Button3. In group2 there are the two labels (Label1 and Label2).
But how can I program that, that if I write (for example) "Group1.Hide()", then everything In Group1 hides (visible = false). And so on with group2.
I programatically add a group of UserControls to a flowLayoutPanel control.
sometimes I need to destroy that group of controls, but have no idea on how to do it.
assigning the flowLayoutPanel variable to nothing only erases the pointer, but the controls remain in the window.I have found a page in MSDN saying that the best way to destroy a control is to call the DestroyWindow API, to destroy the container window. But I don't want to destroy the container window.
I'm trying to apply a code to a group of labels (actually all the labels but one in particular).I used to use:
For Each lbl In My.Forms.Form1.Controls
If lbl.name.ToString.Substring(0, 1) = "x" Then
'Code
End If
Next
Maybe if I knew the right termanology, I could find the answer myself.. I am going to run a fairly long list of "If"s that will determine if certain controls appear on the form or not. In it's simplest form would be:

How would I dynamically enable/disable group boxes based on a radio button selection? I am trying to do it with two group boxes. The group boxes are called grpSelectChars and grpPWAutomatic. The radio buttons are called rdoChooseChars and rdoRandomlyGen. if rdoChooseChars is selected then I want grpSelectChars Enabled and grpPWAutomatic Disabled. in the load sub I have rdoChooseChars Checked
Private Sub PWGenerator_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I was wondering if there is a way to group controls together without using any containers such as panel, group box, or container.
View 4 RepliesI have a group of controls dynamically added to a forms with a name like "OptionID_#" where the "#" is unique number.1st I need to check if these controls are checked/unchecked, but am having a difficult time even finding them to make that first check.I thought controls.find might work, but Controls.Find ("Option ID_" True) dues not seem to find my controls.2nd I need to get the "#" from each of those checked options.I think that Split(conControl.Name, "_") should work to get me two different parts one with the OptionID, and the other with the "#".Still stuck on the first part though of actuall locating the controls I need.

I have a form with many buttons on it and I would like to loop through all the controls in a group control and find out which button is clicked.
I plan to use the click event of the button and I know it's easy to create a click event procedure for all of the buttons but would like to avoid that.
The group control is called GroupFilterButtons.
So basically what I'm trying to do is write data from an XML file (a "save file") back into the form. My controls are in all different group boxes (makes it much easier for showing and hiding groups of controls dynamically). I thought about and am putting each control's Parent name into the file, but can't figure out how to get that parent name back into the DirectCast within a For...Next loop so it will actually cast the data into the control.
[Code]...
is there any way that i can set the property of a control all at once? like for every button, i want their backcolor to be red. something like that.also is it advisable to set the properties of a control in design view rather than code it? does it have any performance issues?
View 3 RepliesI recently uninstalled an IDE for a motion control system (Delta Tau) that is a visual studio based product. Now when I bring up my Visual Basic 2008 IDE that I'm using to write an HMI for the control system, the properties for controls placed on forms doesn't appear in the properties window. And if I click on properties for a form I get the FileProperties2 information, not the form control properties such as size, location, or color. I am also not able to access the controls in the VB toolbox to place on a form. The controls are grayed out and unavailable. what part of Visual Studio 2008 got broke in the Delta Tau uninstall?
View 13 RepliesI'm trying to write a routine which will produce a list of the values of some of the properties for every control that I've placed on a form. I can do this manually by looking up the names of each of the controls, but I'd rather use a construct like this -for each formname as string in xxxx
for each ctrlname as string in yyyy(formname)
....
next

However, I'm having problems with the various examples of this code that I found in the library. I'm not sure whether it's because I don't know how to set up the syntax correctly or this sort of construct isn't possible in this context.
1) How is the Name property hidden for controls for the Properties window yet it is shown in Intellisense?
2) For a System.Windows.Form.SplitterPanel the Name property is not shown in either but you can still Get or Set it.

I have yet to find a "nice" way to do two way databinding in .Net. The one thing I don't like for example in the present asp.net two way databinding is doing the binding in the aspx page is no compile time checking, ie:
<asp:TextBox ID="TitleTextBox"
runat="server" Text='<%# Bind("Title_oops_spelled_wrong") %>'>
I would like to have something like this:
Class Binder
Public Sub BindControl(ctl As Control, objectProperty As ???????)
'// Add ctl and objectProperty to a collection
End Sub
What I don't know is possible is, how to receive the objectProperty in my example; I want to receive a reference (ie: a pointer) to the property, so later, via this reference, I can either read from or write to the property.
Can this somehow be done with delegates perhaps??
UPDATE: Note, I want to add the control reference to a binding collection, this collection would then be used for binding and unbinding.
In my project, I am trying to change the visible property of my various pictureboxes using a for - next statement.

In my asp.net 4.0 application I have a standard set of tabs controls across the application that has one tab for Search, one for View and one for Reporting.I am in the process of updating those tabs and I was hoping to be able to wrap their functionality up into a single user control since they all function in pretty much similar ways. The issue I am having is how to create a property called SeacrhTab/ViewTab/ReportTab that allows me to assign a different user control to it depending on the area of the application (e.g. CompanySearchControl, ContactSearchControl, etc.) Anyone ever tried to accomplish something similar?
