The code below loads 4 Tab Pages at runtime to a TabControl. If I have UserControls in my toolbox, I can't just drag and drop the user control onto these TabPages because they don't exist yet! How do I accomplish this dynamic loading of UserControls onto the Tab Pages as they are created?

I created a server control which consist only of fews buttons.
CWNavigation.vb
<ToolboxData("<{0}:CWNavigation runat=""server""></{0}:CWNavigation>")> _
<DefaultProperty("Id")>[code.....
I then referenced it in my ASPX page. Take note that the control are in the same solution, same project located in Commun/Navigation/CWNavigation.vb.
<%@ Register TagPrefix="NAV" TagName="CWNavigation" Src="~/Commun/Navigation/CWNavigation.vb" %>
I added it to the page.
<NAV:CWNavigation ID="CWNavigationService" runat="server" />
But the designer file along with the code-behind generate it as.
Protected WithEvents CWNavigationService As Global.System.Web.UI.UserControl
I created a UserControl in a ClassLibrary project and then built it to generate the .dll file. I then want to create a new project and i added this .dll as a reference to my new project. but how do I add the UserControl in the class to my Toolbox? I'm using Visual Basic 2005 Express Edition.
View 2 RepliesI made a control that inherits directly from ErrorProvider. I thought that applying it the ToolboxBitmap attribute would be enough to get my control to have the same icon on the toolbox as the original control has, but it doesn't. It's strange, as if I add the control to the form, it will appear just as it should, but it doesn't change the toolbox's icon. What am I missing here? I already restarted visual studio and it keeps this behavior.
[ToolboxBitmap(typeof(ErrorProvider))]
public class ErrorProviderEx : ErrorProvider {

View 2 RepliesI have a usercontrol which has a number of labels on it. The usercontrol acts a bit like a listbox but I can control the background and foreground color of the labels it contains - nothing fancy use it for logging a process - a bit like a scrolling console window.I have a form with 3 of these controls, Progress, Errors, and a debug logger. Works fine when placed on a form until I add a tab control with three paces and place each usercontrol on a tabpage. then random labels are not updated.
View 14 RepliesSo I've created a very simple UserControl that is pretty much just a combo box that has US States in it and a couple properties to return the selected value as an enumeration or a string, etc.The enumeration and string values I'm using are being referenced from an external library which is working. However, when I add my user control to another project the designer-generated code has errors in it. [code] I would assume that this probably has something to do with project settings or something similar for the user control. The control itself is in a separate project and compiled as a .dll which has been added to my main project's toolbox and subsequently added to my form. [code]
View 11 RepliesMy boss has given me an asp.net web application that was done by his former employee. Now my boss has no contact with that employee. He wants me to make some changes in that web application. I went through the application. There is no documentation present for that application . Its a huge application. It contains many directories. I think it was a team work. It has many asp pages, aspx pages, jsp pages, xml pages, css pages, etc...

View 4 RepliesI have created a custom UserControl, with a custom designer, which contains a Panel which is editable. Any controls dropped onto this Panel will go off-form when an Anchor is set. This was already reported here and acknowledged as a bug:[URL].. Are there any known workarounds? Or available hotfixes for this issue?

I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!

dynamically creating buttons with images in them and then accessing the on click event for that button. However lets say for example I have three buttons created during run time, button 1, 2 and 3 for simplicities sake. Each button needs to correspond to a value (lets say one, two and three). The problem comes in when i want to, for example, click on dynamically generated button 3 and have it display "three" in a message box. But button 2 might close the program. How can i reference an event when i don't know which button corresponds to which action..

View 1 RepliesOn my main form I have a 9 button grid that I need to fill with a gradient colour so that it represents a "heat map" going from Green (lower left) to Red (upper right). The "heat map" needs to be generated dynamically as - if I use an pregenerated image I have noticed colour variances when working on different screens / projectors as in the app there are other dynamically generated graphics & the two sets of colours need to match.So to achieve this - on my main form I have a PictureBox that I fill with the gradient colour.On top of the PictureBox I place my grid of 9 buttons.I then hide each button & take a screenshot of what is behind it & that then becomes the background image for the button. The button is then made visible.All works fine when I am testing in on a simple form The issue is that this arrangement needs to be placed on a tab control & I'm having difficulty replicating what I could do successfully on the simple form.....
Code for the colour gradient :-
Dim A As Integer
Dim B As Integer
Dim C As Integer
Dim D As Integer

View 2 RepliesI made a custom control that is a 15x15 grid designed to show a tiled map. Inside I have a class that inherits from pictureBox. The problem comes when I try to place my DLL inside the toolbox. When I click "browse" and select my DLL to import it simply import my class inheriting pictureBox instead of the whole package.
Here is a picture of my files. Grid.vb is the control, clsTile is the pictureBox class and the other one is irrelevant. [URL]
I made a customized TextBox that I'd like to permanently add to the toolbox. But when I close the project that I created it in, my new control also disappears and I have to copy/paste or import the class-code every time I want to use it. Is there a way to get the control in the toolbox "forever"?I tried to enclose the class in a "Namespace CustomClasses" statement and changed the root namespace in the project properties to "CustomClasses", but nothing of what I tried is permanent. I prefer to store my classes in a "real" root namespace, in the same root as the microsoft and system namespaces.

View 6 RepliesI have created a Stored Procedure in SQL which produces a pivot table. I've successfully created a GridView in ASP.NET to display this data.
However, some of my column headings are dynamically generated from the data (AutoGenerateColumns=True), and those column headings are just dates, so they will look different almost every time the table is generated.
This all works fine, except that the date format of the column headings is wrong. I know I could change the way SQL produces the dates in its output, but I don't want to do it that way. I want to control it from the web page.
I didn't think this would be difficult - I thought I could just do something along the lines of finding the cells in the header row and changing the datastringformat. The problem is that whether I put my code in the GridView's DataBound or RowDataBound event, the cells in the header row seem to be empty, so I can't reformat them. It's as if the headers get populate some time AFTER the DataBound event, but I don't know when or how to trap it.
I have used the following code to generate buttons dynamically.

To set the scene, I have implemented a drag and drop rearrange in a FlowLayoutPanel (thanks to a few good Tutorials) which worked absolutely fine until the client decided that he needed many Panels each contained in the Tabs of a Tab Control.Ironically the FlowLayoutPanel rearrange still works if the panel is not in the Tab Page. However the moment it is it stops functioning completely.In all honesty its probably a simple issue that I'm missing but I can't seem to find an answer. I'm certain that the issue is in the following block of code, most probably in the following place:If controlcoll(i).Bounds.Contains(mouse.X - flow.Left, mouse.Y - flow.Top) Then Either that or in a property of either of the controls. [code] The Panels, Tabs and Buttons (which are what need to be rearranged) are all dynamically generated.
