I have a problem with SQLDependency I have took an example from msdn and changed it a little to my purpose but somehow it seems the event never fires up. What I did until now is
1. changed the database owner
2. enabled broker
3. also my query is fine i'm including the shema name.
Here's my code

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 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.
View 2 RepliesI 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 use Visual Studio 2003, VB.net, NetFramework 1.4 and Windows XP I have been using the following Code Snippet for a number of years in both Web Services and Windows Applications. However suddenly around the 29th September 2010 it has stopped sending E-Mails from both Web Services and Windows Applications. The same problem has happened not only to my own Network but on two other Networks, one using XP as its Server and the other using Server 2003. All 3 of these are using different ISPs.

I have a menu on my aspx page which looks beautiful. It's exactly what I need (found it here).
Problem that I have is this: I need (somehow) to kick off a button control from the javascript. I realize that in the example, the menu items are simply href links, but I'm wondering how I could possibly do a postback and kick off my Button1_OnClick event.

I have a modal popup that has a targetId to a hidden button. I want the popup to occur when a button in a grid is clicked but that button is programmed behind the code and therefore the targetId would be invalid. So I wanted to attempt to set the gridview's button's onclientclick event to be the onclientclickevent of that hidden button. Is this possible or should I be going about this another way.
Here is how I created the grid button
If Not IsPostBack Then
Dim field As New TemplateField
field.HeaderText = "Sub Departments"
Dim col As DataControlField = field
GridView1.Columns.Add(col)

I was perhaps too quick to think that VB's built-in event would be be easy to use. As you can see from my previous post I am building a program which sends and receives a few bytes from serial bus. The bus is actually a usb serial adapter, there are no real serial buses in my machine.Anyway that SerialPort1.DataReceived does not fire. It is from visual studio/vb ide so syntax should work? Here is my start up code. There are many comments, because I tried various combinations.
If Not _serialPort.IsOpen Then
If Not arvo = "" Then
_serialPort.DtrEnable = False
_serialPort.Parity = Parity.None

I can't seem to get the Form.GotFocus event to fire.I have two forms - a main window and a debug window.The debug window will always be shown with the main window. But, I don't want the debug window to appear in the task bar - it's unnecessary.While my program is running, when I select another program, my main window and the debug window are placed behind the program that I selected. From the task bar, I can bring my program back to the front by clicking on it in the task bar. The problem is, that now my debug window is behind the other program.I have code that will "DebugWindow.BringToFront", and it works. But I need some way to run do this when the main form gets the focus.I do not wish to make any of my forms Modal. At least not permanently. If the solution is to change the modal property of the form temporarily, then that wouldn't be a problem.
I tried Me.Enter, Me.Activated, Me.Click and a few other events. Me.Click only works when I click within the Form window, not the form's title bar. Me.Activated caused problems - The code ran, but it would always end with the focus on the Debug window. When I tried to click on the main form, the Activated event would fire again, sending the focus back to the debug window.[code]
