I am using VS2008, vb.net, Windows forms project.I have a combo box control on a tab control.The selected value of the combo box is bound to a binding source.The data source of the binding source is a typed dataset.I set the datasource of the binding source when a record is chosen in a data grid control.Since the combo box is bound to the binding source, this should set the selected value of the combo box, and fire the initial SelectedIndexChanged event.Therefore, I remove the SelectedIndexChanged event handler for the combo box before I set the datasource of the binding source, and add the handler again after the datasource is set.

I have added the AutoPostBack = "true" attribute to the drop down list. It doesn't work.
<asp:DropDownList CssClass="dropDownList" ID="ddlBusinessUnit"
AutoPostBack="true" runat="server" Width="250px"
OnSelectedIndexChanged="ddlBusinessUnit_SelectedIndexChanged">
[Code].....
How can I ensure that the event method is called?

I have a GridView which you can click on a row and it should call the SelectedIndexChanged method (which updates another part of the page based on which row was selected). I have done something similar to this before and it worked, but I can't seem to get the SelectedIndexChanged part to be called for some reason.The page is held in a master page which has a form runat="server" tag, and an <asp:ScriptManager> tagI am using e.Row. Attributes.Add("onclick", ClientScript.GetPostBackClientHyperlink(Me.gridMessages, "Select$" & e.Row.RowIndex)) to allow the SelectedIndexChanged to fire by clicking anywhere on the row.To check that the code does work apart from that, I added a CommandField with a SelectButton and that successfully fires, but i would prefer to find a solution without having to use that.[code]

I'm getting spotty results trying to build a procedure that queries Yahoo finance, retrieves a stock quote and then passes the HTML body contents to a text variable. Using a WebBrowser control, it works in a 2 step fashion, using a textbox to input the symbol and a button to trigger navigation. After the WebBrowser window fills, I can pull the contents out of the browser window. In this case, it's just one number to keep things simple. The working code appears below:

I'm developing in VB.NET with Visual Studio 2005.I have a ComboBox (myCombo) on a form that gets populated within the Load method.I also have handled myCombo.SelectedIndexChanged to change a label on the form.
Edit: The way I added the event handler was by double-clicking on the combo box on the designer. Skeleton code then came up in the code view.It looks like what's happening is when the form loads, SelectedIndexChanged gets fired each time an item is added to myCombo.This isn't what I want, but I'm thinking there's another event handler that only gets called when the user changes the selection.
Here's some code for what I have:
Private Sub myDlg_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' this is all I do with myCombo in this sub
list = GetListOfItemsToAdd()
[code].....
Update: The solution I used was to remove the Handles clause after the event generator, and add this before the "End Sub" above:
AddHandler myCombo.SelectedIndexChanged, AddressOf myCombo_SelectedIndexChanged

I have a user control (SomeUserControl), that I am using in a Main Window. I write my application entirely on SomeUserControl, and Main Window is hosting SomeUserControl and nothing else.
Right now I have a shutdown button (in SomeUserControl), that is supposed to close the Main Window. The reason for this is that I do not want anything from SomeUserControl to close the application itself, but to fire an event from SomeUserControl, and Main Window receives it, and Main Window will close the application instead of SomeUserControl.
How do I do it? I am not familiar with the concept of creating and handling custom events, so if someone could explain it in words and in code as an example, I will be very grateful to you!
Edit: Here's my code so far.
(in Window 2)
Public Event CloseApp As EventHandler
Private Sub CancelButton_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles CancelButton.Click
DialogResult = False
[Code]....
I want to close the application when I click cancel in Window 2, but I don't want to do it in such a way that Window 2 closes itself, but by sending some notification to Main Window, and Main Window closes the application.

I need a multiline TextBox which is always disabled, but it shouldn't paint itself in gray, but I want to keep its designer choosen color. I previously had the same requirement with an always-black Label (no multiline) and so I inherited from Label like:
Imports System.ComponentModel
Public Class LabelDisabled
Inherits Label
Sub New()
InitializeComponent()
Enabled = False
End Sub
[Code] .....
But this way, neither I can set the "real" Enabled property, I mean the backing field.

I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a <div> tag with visible=false.
Example:
Page code -
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="act" %>
[Code].....
I have a breakpoint on the UploadedComplete event but it never fires. However, if you take the AsyncFileUpload control out of the <div>, making it visible at initial page render, the control works as expected.
So, is this a bug within the AsynchUploadControl, or am I not grasping a fundamental concept (which happens regularly)?

I have a situation where I'm allowing users to enter new values into a combo box or selected existing values from the combo box's drop-down list. Is ther any way to tell whether a value was entered or selected? I've looked at the TextChanged and SelectedIndexChanged events and neither will do what I need to do.

I am using VB 2010 express edition, using windows form, i set my access database using the database connection wizard, and then use a combobox and bind it to the database using the properties windows, while other fields of database (set in textbox form), i drag it to my form. Running it, the values of textboxes are correct when i changed the value of my combobox. I want to use these values in textbox in drawing circle, whenever i change the value of combobox, the circle will also change using the combobox selectedIndexchanged event, my problem is, the value in textbox does not update in order to draw the circle, i have to use lostfocus or leave event to correct it. I make also a combobox and textbox not using this Ado.net(correct me if im wrong), it is working using the selectedindexchanged event only, what seems be my problem,

On a form I have a DataGridView. Inside this DataGridView i have several columns of which one is combobox and the others are textboxes.The combobox column is populated with values from a MySql database table using a query. So far so good. What i want next is to populate a certain textbox from that DataGridView, automatically after a value from the combobox is selected. When a value is selected from the dropdown list of the combobox, that value is used in a SQL query to find the value that will be displayed in the textbox.All the textboxes and the combobox are inside the DataGridView!)I did this using DataGridView EditingControlShowing event because a DataGridViewComboBoxCell does not have aSelectedIndexChanged event.The value is displayed correctly in the textbox, but the problem is that the value selected from the combobox disappears after the selection, and the combobox remains empty. I need the value to remain in the combobox after it was selected and after the corresponding value was inserted in the textbox!Here is the code for this:
Code:
Private Sub test_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have combo box selectedIndexChanged events going on but I cant figure out how to get the value out of them so that when i hit the btn_ProjSal that the new salaries show up in the 3 labels. Here is my code. Doing it straight from the selectedIndexChanged event this works..but to get the button to pull the new values from each of those events is my issue.
Public Class Form1
Dim _emp101Sal As Decimal = 10000.0
Dim _emp102Sal As Decimal = 11500.0

I have a ListView that populates some fields whenever the user selects an item. However, if they change the data in the fields and then select a new item without saving, I want to display a message box that warns that their changes will be lost, and asks them to confirm whether to continue. Sounds simple.
Unfortunately, the ListView's SelectedIndexChanged event cannot be cancelled, and it's actually called for each change in the selection. So, for example, if item 1 is selected and the user then selects item 2, the event is called twice: once to remove the selection of item 1, and then to add the selection of item 2. If you go from having one item selected to having five (for example), the event fires to remove your original selection, and then again for each of your new selections - six hits in all.
Obviously, this makes it a bugger to determine when the event should be cancelled and reset back to the original. I obviously don't want my message box appearing six times....

I have a ComboBox that contain ProductIDs and a DataGridView that lists Categories which a product can be a member of. My DataGridView list ALL categories, however, it has a checkbox column that get checked when the ProductID is a member of that Category, otherwise it is unchecked. A user may also check or uncheck a category checkbox then save.
The problem is, if a user forgot to save before changing the ComboBox, then his changes on the previous ProductID is gone How can I give the user a chance to either save or ignore the changes done on the previous ProductID (before selecting a new ProductID)?I searched the internet for an answer and I found the following code but it is in C# and I am not sure if it solves the problem or not!

I have some experience developing for VBA inside Office apps, but I am quite new to VB.NET, and I just noticed that its WebBrowser control is a bit different from that one I used to reference via ShDocVw to use in my VBA Forms.ShDocVw.WebBrowser had the DocumentComplete event, which passed these arguments: URL as string and pDisp as object..NET WebBrowser has the DocumentCompleted event, in which i successfully found e.URL.ToString, but I couldn't find nothing similar to the pDisp object.
This is critical to me on migrating my project from VBA to VB.NET, for I need to handle particular IFrames when they complete loading, which I only could do by getting pDisp's document property. So I need help on learning how to do the same thing with this .NET WebBrowser control, and/or how to reference and use good ole ShDocVw.WebBroser in my Visual Studio project, to embed it in my forms.

I'm trying to handle browser popups using the NewWindow event of the WebBrowser control. The one main thing I needed is the cookie from the main browser control on my form to be passed to the popup window. Below is the only way I've been able to open the popup and pass the Document.Window.Opener value to it so that when java script is executed, it knows where the opener window is. I am getting the following error right now when trying to set the cookie from my webbrowser control to the iexplore instance of the popup window that opened.

First off I hope I'm in the right forum.I have an application I built with the WebBrowser control in Visual Basic 2005. I am using the DocumentComplete event to track when a page has fully finished loading as some of the webpages I need to work with have frames.
The problem I am having is that when some iframes time out or don't load, the documentcomplete events stop firing. So if my webpage has 2 frames on it, we'd expect 3 documentcomplete events. One for each frame and one for the parent document once the frames have loaded. If say frame 2 does not load properly, the documentcomplete event for the overall document never fires.
