In this partial view I create new ViewDataDictionary to pass additional data to my editor. In the editor I access ViewBag.Classes and its value is null. However, when I debug I can see that the ViewBag contains "Classes" key. Here a screen dump:
Why is this happening to me and what can I do to pass this value from a partial to editor template?
I have the following button:[code]I have the following method but looks like it is not hitting the method:Protected Sub lnkEdit_Click(ByVal sender As Object, ByVal e As System.EventArgs)End Sub..Wondering if I am missing something. I put a breakpoint on the Protected Sub lnkEdit_Click but on click of the imagebutton I do not go there.
I am using a monthcalendar inside of a panel. when the user changes the "showweeknumbers" of the calendar I need to move some label to the right of the calendar, but I also need to resize the panel. The problem comes into play when the user hides the weeknumbers, the monthcalendar resize event fires and the labels move, but the panel resize causes the month calendar to fire the resize event again, making the labels all out of wack...
Private Sub Exceptionquery() Dim connection As System.Data.SqlClient.SqlConnection Dim connectionString As String = "Initial Catalog=mdr;Data Source=xxxxx;uid=xxxxx;password=xxxxx"
[code]....
I get the error Invalid Object name 'Scratchpad3' on this line:
adapter.Fill(ds)
I have tried to debug this and can see that the query is correct, that the values that are being passed to the sql server are correct but it doesnt look like my code is firing off the Exceptionquery Sub. I thought to call a sub all you had to enter was the name of the sub such as this line:
Exceptionquery()
I have also verified that the mapping of the buttonclick event is mapped correctly. I have other subs that I am calling in almost the same way and those work.
I am creating a dropdown list in code for a gridview. I want to create an addhandler so I can have access to the selectedvalue. However, here (Rowdatabound) the add handler does not get fired off. How should I go about this?
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound ''//------------does not fire off add handler-----
I've been looking for a solution to this for several hours now and cannot find a solution.
The Scenario:I have a masterpage baseclass (called basemaster)All of my master pages inherit from basemaster basemaster defines an event 'Public Event HandleClickEvent As EventHandler'I have a masterpage named master1 master1 defines an event handler 'Public Shadows Event HandleClickEvent As EventHandler'master1 has a user control named usr1 usr1 has a button that raises event ButtonClicked when clicked I have a page (thePage) that uses master1 thePage has a button click event handler that it registers like so: 'AddHandler Master.HandleClickEvent, AddressOf HandleTheClick' master1 has code something like:
Protected Sub Usr1_ButtonClicked(ByVal sender As Object, ByVal e As System.EventArgs) Handles Usr1.ButtonClicked RaiseEvent HandleClickEvent(sender, e) End Sub when thePage loads I see it register the handler on master1 when the button is clicked, Usr1_ButtonClicked is fired and I step through the RaiseEvent but HandleClickEvent on thePage is never reached.
I am upgrading a 1.1 web app to 4.0 and am running into an issue with the page_load of a custom user control firing twice, both being treated as non-postbacks (IsPostBack is false in the case). I have read around and it seems that there are 2 culprits to this, 1 being an img tag without something in the src part (which there are no images on this page at all) or 2 an issue with AutoEventWireup and Handles being used at the same time. I have looked through all my code and there are no Handles keywords in there at all and AutoEventWireUp is set to true on every page, yet I still get this issue.

The problem im having is a little complicated to explain, so please bear with me. I have 2 button controls. In the page load, I wanted to know what button created a postback on the page load. Through research I have found this snippet below and it works as expected. So here is my scenario of events that occur when click on the button.
1. Click the button does a postback 2. Runs the function below and tell me the id of the button 3. Runs the clicked event handlers for that button [code]
The problem comes in when I click the second button, it does steps 1 and 2 but NEVER DOES 3. Through testing, I have that it only does 1, 2, and 3 on the first button clicked.[code]

Can you write code to tell an event not to fire? Sometimes in my applications events fire unexpectedly. I know this is a broad question, but it must have happened to others out there.
[url]...and have applied the vb code. The problem I have is that the user doesn't navigate within the datagridview. They click a save button on a toolstrip. As the user doesn't move from the current cell then the cellvalidating event doenst get fired. [code]...
We're trying to design a toolbar to use as an addon in another program. we want to set one of the buttons so that when u single click it, the image on the screen is blanked out. And when you double click the same button, it blanks everything except the selected image. However the DoubleClick event doesnt seem to be working at all.

I have two forms that I worked on separately, each has an event load button that works with a datagridview without any problem. but when I created a third form and moved the buttons on it and try to update the datagridviews on the two forms, it doesn't fire up here's my
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Below is my databinding code. It is called from Page_Load()

Bind data to datasource of dropdown control when it is not postback Control was added from toolbox tried adding event handler in .aspx. Still did not work.
I've bound a bindingsource to a datagridview and each time i move the cursor on the datagridview to a different row, the positionChanged does not fire. This event handles other bindingsource too and I hv no problems with other datagridviews.
Im couldnt work out the behaviour for this particular datagridview.
I made my application single instance using the Mutex example from the codebank (converted to VB).
If I place If Not FirstInstance Then Application.Exit()
in the Form_Load event of the main form, the form will show briefly before it is closed (on second instance). So I thought the way around this was by using Sub Main() (as I plan to add commandline support later), but the event is not firing with a MessageBox test. Where does this code need to go to avoid having the main form show briefly?
Converted Mutex Public FirstInstance As Boolean Public Mutex As Mutex = New Mutex(False, "<ID>", FirstInstance)
.net 4.0, ASP.net, vb.net. I've got a usercontrol that is using an obout combo box. The obout is a cascading combobox that has 3 levels to it. when something it selected from the third level of the combobox, it is suppose to fire off a selectedIndexChanged event. This happens the first time that I select the usercontrol. The problem is if i want to go back and select something different. The selectedIndexChanged doesn't fire. I've set breakpoints and the AddHandler ComboBox3.SelectedIndexChanged, AddressOf ComboBox3_SelectedIndexChanged
runs just like it did the first time i select the usercontrol. But the selectedIndex just doesn't fire the second go around. Was wondering what i'm doing wrong. Here is the selectedIndexChanged that is not firing
I have a MDIParent form and 2 child forms. One of them,form1, has a textbox for which certain validations are present in the validating event. The other one has a button on it. When I try to navigate from form1 to form2, the validating event is firing twice for the first time. Is there a way to make it fire only once. And also, this event fires whenever I try to close the mdi parent form Attached is a sample project.
Program was working fine, now all of a sudden it decides it does not want to navigate for me...It doesn't appear that either of my DocumentComplete or DownloadComplete Events are being fired when navigating to a very minimal web page.I even tried deleting the code blocks, and "re-adding" them in the IDE. no dice.This is pretty much the most important part of the whole program. arggh.what could be causing this? I tested by placing a msgbox call in the Document Complete Event. no popup*
I am running VS 2008 and building my app on a Windows 7 box. The main form/window has a KeyDown event handler as follows in it:
Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown MsgBox("control = " + e.Control.ToString + ", shift = " + e.Shift.ToString + ", e.Keycode = " + e.KeyCode.ToString)
When I build it and run it within VS it seems to run fine. The messagebox appears with the state of the control and shift keys along with the key code of the key I pressed. However, if I take the executable and run it on an XP box (both using .Net Runtime 3.5) as soon as the main form opens, the messagebox appears. Basically the "KeyDown" event seems to be firing without any keys being pressed. The messagebox comes back with: "control = False, shift = False, e.Keycode = None".
How is this possible? How can the keyDown event be fired when no keys have been pressed (as is confirmed by the output contained in the messagebox?) how I can diagnose this on the XP box since it does not have Visual Studio on it?Update I tried creating a brand new project where there is only "form1" and the only code behind this is the keyDown event handler. It just opens a blank window and pops up the message box if a key is pressed. It worked as expected on the Win 7 box but when I moved the executable to the XP box, it immediately popped open the messagebox without pressing a key.
I am developing a Vb.net .Net 3.5 PDA application using the OpenNetCF IOC framework. I have set up and event to handle the navigation through the smart parts but when I raise the event the EventSubscription does not fire.
