I'm using a recursive search to find all of the controls on my form and then do something with those controls once I find them.This is the basic layout:
Form
-----CustomPanel
----------PanelChild
[code].....
I've made my first little custom control. It is a textbox, then next to it a picture. I've written the code already for the picture box. It basically opens up a new form with a listview on it that displays details from the database. But now, I still want the text box to have the basic properties of a normal textbox like text alignment, enabled, backcolor, etc. But not sure how to do this.
[Code]...
I have made a form that consists of textboxes nested in groupboxes nested in tabpages. I want to check if all textboxes are empty in every groupbox and even if the controls from a groupbox in a groupbox are empty.When they are empty i should not create an element string for my .xml document.Below is the code that I have at the moment. I call it with the form as the parameter.
Public Sub recurringControls(ByRef ctl As Control)
For Each c As Control In ctl.Controls
If c.Controls.Count > 0 Then
If c.Tag IsNot Nothing Then

Is it possible to have a custom control (inherits from Control) and add sub-controls to it (like, a label for example)? Basically I want a composite control. I know controls can contain other controls, but if I try to add a control to MyBase.Controls, this doesn't work because that's readonly.
[Code]...
I have a form named VBProject It has two TextBoxes and one custom control named MyControl which is created in another project.MyControl's project has a form inside, named Form3. When My control is loaded it needs to find all controls in my VBProject and add them into a listbox which is in Form3. Then Show the Form3. In the end ListView need to shows name and text of textboxes but it shows nothing. Here are my codes:
MyControl's Load_Event:
Dim i As Integer = 0
MessageBox.Show("Control Count:" + Me.Controls.Count.ToString)
For Each MyObject In Me.Controls
If TypeOf MyObject Is TextBox Then

[Code] I have a panel as the base of my custom control and I am adding other panels to it, along with a flow layout panel(myInnerContainer). I know the code above isn't going to work because when I try to add the regular panels to the main control, they will attempt to be added to the flow layout panel myInnerContainer, and cause a circular error. [Code] but intellisense doesn't display anything which leads me in the correct direction for adding only the buttons to the flow layout panel (myInnerContainer).

I wrote a Windows Forms script that searched for all non-hidden and non-readonly folders in my system. But the script itself, when run initially, runs for like 5 minutes. Subsequent opens take much less time. I was wondering if there is a logical error to it, so as to why its running so very slow.

What I want it to do is to have it return an array of relitive file paths, from the starting direcotry I give the function. Then I will use a loop to cycle though each file in the array to make certain changes.
Something like this:

Any ideas on how to acomplish this?
Is this possible? Must be surely but I've tried and come up short. I've created a very basic class (person) with 2 public properties, forename, surname. My user control is databound to this class and has 2 textboxes to store the properties.
I've built the control and can add the user control to a windows form but how can I add to a new user control (Staff) which will show my 2 existing textboxes and I can add dateJoined datepicker also??
I got a third party control from a website after googling.Inorder to use that control, I simply right-clicked the Toolbox and selected "Choose Item". Then Browse to that dll file location and selected that file.Now it is added to the toolbox. But do I have to register the dll now ? Or, will it work when I distribute my app ?
View 6 RepliesI need to know how to make Custom Windows Controls?
View 2 RepliesI have a custom control that the User can add to the form. They can add as many of these controls as they like.When they add a control, I am going to populate another custom control, a textbox, in another panel.I need to figure out how to associate that new control with the previous one.So, let's say the User creates 3, let's say "Boxes", three TextBoxes are created. When the User adds something to Box1, TextBox1 needs to be populated a specific string.I know how to create and add the control as needed, but I can't figure out how to associate the controls, if that make sense.In order to distinguish the Boxes, I've added a label to them that represents each iteration of the box. The numbers start at 1 and increase from there.I was thinking I could use that to associate the TextBoxes and am working on that now.

In THIS Thread:NickThissen Said:Quote:It will appear in the toolbox even if you put it in the current project, instead of a control library project.No, it does not have to be in a control library, nor does it have to be a UserControl, to appear in the Toolbox. Any class inheriting (either directly or indirectly) from Control or Component will appear in the Toolbox. Since RadioButton inherits from Control, and your control inherits from RadioButton, your control inherits from Control too, so it will appear in the Toolbox. I have successfully created a pretty cool custom control. I Built the project and have added the a reference to the .dll form a new Windows forms project. It works great, as long as I do something like THIS:
Dim ThisControl As New MyCustomControl
ThisControl.Top = 40
ThisCOntrol.Left = 40
[code]....
I have the above control I am using, whose base class is the ListBox.Unlike the ListBox, it doesn't highlight a new item when it is inserted.I already had to add the ability to InsertAt() a new item since the person who made it originally hadn't implemented that part.But, I am having trouble figuring out how to make that part work.The above link is directly to the original Control.Here is the code for the Insert method I added:
Public Sub Insert(ByVal index As Integer, ByVal value As MCListBoxItem)
Try
List.Insert(index, value)

I have several custom controls inside my project, just added a new class and then inherit the original control. For example i have a Custom DataGridView Control (CustDGV), that defines several properties in the constructor of the control.Now i have one problem and one issue, the problem, if i change the CustDGV i don't know why, the forms that are using the control doesn't update the changes... The only way it's removing and adding it again.. not very useful when i have several event's already defined for the dgv.How do i force the form to update the control?The issue it's that some of the properties doesn't get applied, for example i set the column header height and the disable resizing in the constructor, but if i run the code this two properties doesn't get applied, i need to define them in the form where i use the control to get the results that i expect..The order of the properties in the constructor? The properties in the properties window override the constructor ones?
View 17 RepliesI have a custom control I've created, and I'd like to be able to step through it (either in a test application or the one it's being used in). Is there a way to do this?
View 1 RepliesI have a panel that has 9 pictures boxes within it. I need the User to be able to create as many instances of this control as they like.
Then each control needs to be able to move freely within the form.
I've created the control and added the appropriate code to move it around the control.
I've made the control canvas the same size of the panel. The problem is that when I move the panel, it only moves within the bounds of the control canvas. I guess I could increase the size of the canvas, but then additional controls would still only be able to move within their bounds and it would come out all wrong.
Is there anything I could do about this? Or is there a better method?
This relates to WPF but is broad enough that a winform answer will do. I have made a few custom controls in the past by inheriting from whatever particular control I wish to inherent from.
I have noticed that I can add a form to a class/user control library from the add new dialog and have it run. When this application is compiled I get a DLL.
So my question is can I use a Form as a custom control. The reason I ask is I am creating a more advanced MsgBox for a new application I require and a form as its container makes the most sense.
I have created a custom control in one VS project. Once tested and built, I then copied the object over to a structured class library type project I hope to use as a code repository for these kind of things. To ensure I can get to the control, I created a test project and added this repository dll as a reference. The problem is that I cannot see the custom control in the toolbox.
Is there an attribute or something I should've used in the repository dll in order for this to happen?
My objective is to create a custom namespace in this repository dll so that any custom objects or controls can be referenced in various other applications without having to copy the objects to each. I know my reference is good as I can create the control in code. I would just like to see it show up in the toolbox!
I created a custom control and I'm trying to insert it into a panel, but also center it.The control itself is larger than the panel, so I've set the AutoScroll property of the panel to True. I think that might be affecting it. Perhaps I should just offset the Y axis a bit.But, either way, this is what I'm trying:
VB .NET
'Create the control
Dim AutomationReport As New AutomationReportControl
[code]....
It works just fine with the X axis, but the control is out of bounds vertically. About 1-2 inches of the top is cut off.
