I have an application in which a user fills out a form indicating their interest in a service. This includes contact info. (e.g. name, email). They are then redirected to a page with a CreateUserWizard control - the idea being that it will prepopulate the form with most of the info. needed to create a user account (excluding username/password which need to be entered manually).
[Code]....
I'm extending the ComboBox class in VB.NET and I'm running into a problem prepopulating the collection. I try to do so by using Me.Items.Add() calls in the New() sub. However, once I place the control on a form in the form designer, Visual Studio automatically adds those items to the collection in form designer, then they are added again at runtime. How can I make them only added once?
View 1 RepliesUsing <System.ComponentModel.TypeConverter(GetType(System.ComponentModel.ExpandableObjectConverter))> _
on the declaration of a class (which is a property of another class) that consists of a number properties.
I load an instance of this class with simply ...
PropertyGrid1.SelectedObject = oColumn
Obviously I don't want to manually build the propertygrid in code, I know how to do that.
But here's the problem. Depending on the value of a property, certain other properties should not be visible, as though I'd used the <System.ComponentModel.Browsable(False)> _
attribute on the property declaration.Is there anyway to do this programmatically, without having to handle all the building of the property grid manually>

I'm trying to add a textbox to the initial step of the CreatUserWizard.Let's say it is tbMyTextbox.Now when I add an event on created user, I want to get the value in the field.I thought I could use dim mc as textboxmc = ctype(CreateUserWizard1.Findcontrol("tbMyTextbox"),textbox)mc.text should be the text of the field.But it can't find the control... so I trieddim mystep as CreatuserWizardstepmystep = createuserwizard1.activestepmc = ctype(mystep.findcontrol("tbMyTextbox"),textbox)But it also fails.The example just uses tbMyTextbox.text which just throws a compiler error.

I have a setup/configuration utility that I am making. The form is split the left side has a nodeview that allows the user to select what they want to setup/configure, and the right side displays that screen.
I figured the easiest way to switch between those screens is to place them in a TabControl, but I dont want the tabs to display when its compiled. How can I turn off the display of the tabs?
I have a listview control on a form. This listview control is populated with at times thousands of listviewitems.Part of my process, is running through custom made filters, to hide unwanted items (before they're even inserted into the listview).So as I hinted earlier, the way I hide items that I don't want is by not inserting them at all. I'd like to make a shortcut available, that would allow me to show / hide the hidden items by simply pressing the shortcut.
My problem is that if I do this, I have to 'refresh' the listview items everytime as I do now ( by removing all and re-inserting the ones I want ).Is there no faster / better way than by removing / re-inserting the items ( which takes roughly 2-3 seconds ); which is a noticeable-enough delay? for a 'visible' property on the listviewitem that I could set to true / false, but that property doesn't appear to exist.As it stands, I have to resort to removing / re-inserting the new 'view' every time.

View 1 RepliesI need to change which pages of a tab control are available at different times. Right now I'm just disabling the unwanted tabs (TabControl1.TabPages(x).Enabled = False), but I've got a user who can't comprehend why she can still view the tab page if she can't use it.
So I need to either hide the tabs altogether or disable them such that you can't switch to that tab page at all.

View 39 RepliesI need to temporarily hide the control in SHDocVw.InternetExplorer (IE8) that displays the contents of a web page. Setting the SHDocVw.InternetExplorer.Visible property causes the entire form to be hidden. I only need to temporarily hide the control that displays the web page (i.e., the control that is analogous to System.Windows.Forms.WebBrowser in .Net). The Internet Explorer form and all other controls (including the tab that is associated with the web page) should remain visible.
My first thought is to iterate through all of the child controls of SHDocVw.InternetExplorer, search for the control that displays the web page and then set its Visible property, but I'm not sure how to do this because SHDocVw.InternetExplorer is a COM object.

View 5 RepliesI use a Repeater that's databound to a DataRowCollection and programatically build a table through that. I have something similar to:
Private Sub SubAcctGrid_OnItemDataBound(ByVal sender As Object, ByVal e As RepeaterItemEventArgs)
If e.Item.ItemType = ListItemType.AlternatingItem Or e.Item.ItemType = ListItemType.Item Then
Dim currentrow = TryCast(e.Item.DataItem, DataRow)
Dim acctSummaryTable = New Table With {.ID = "acctSummary" & e.Item.ItemIndex, .CssClass = "minisub_acct_table"}
[Code] .....
I can't pass in the correct element ID, though. From what I understand, ASP.NET transforms the ID I assign into some huge long ID for the sake of uniqueness. For example, I assign a table with the ID 'drillDownTable0' and it spits out 'ctl00_drillDownTable0' in the HTML markup. It worked the first time around, but then the Repeater gets binded to a new row and then I get 'ctl01_drillDownTable0' so on and so forth. I've tried the ClientID, ID, and UniqueID where I add the attributes to the Cells in the code above and they don't do what I need to. Is there any way I can get that ID and pass it to the Javascript function? Or I guess a better question is: When are the IDs generated and can I get to them before the page is rendered in HTML?
I've spent three days trying to get a user control to do some obvious things -- show, hide, and focus among other things. Done in vBASIC in Visual Studio 2010 Pro. The calling program is a Windows Forms Application, while the user control is a WPF Custom Control Library with a single object, a textbox. The reason it's a user control is that this textbox is connected to an async serial device; the reason it's in a Custom Control Library is that I'd like to be able to drop this functioning serial-port-connected textbox into future projects.
No matter what syntax I attempt, the user control (neither the control nor the text box inside it) will Hide(). I've tried every variation I can think of with control.Visible = false, exposing public subs to do the work, etc. When the form appears and characters are typed in the field, the KeyPress routine is functioning -- it will only accept numeric digits.
Here's the vastly reduced code to illustrate the problem:
Calling Windows Forms Application
Imports DTRFormsControlLibrary2
Public Class Form1
[Code]...
In spite of the call to sbControl.Hide(), the form opens with a very visible and enabled user control text box. The ability to control visibility, focus, and enable/disable seems fundamental to any control.
