I'm trying to create Command Buttons dynamically, but clicking the button in question doesn't seem to raise the corresponding CommandButton_Click event. I noticed that in the examples on SO a property is set for Button.OnCommand as well as the CommandName and CommandArgument but it isn't an option in intellisense.(code below without the OnCommand), is it accessed in some other way - if so, why do the examples I've found all show it as .OnCommand?
EDIT: Further to help, I have added the handler however the event is still not firing. The buttons reside in an UpdatePanel and are rebuilt on every postback (along with the handler). I have created a simplified example of what I'm doing which is shown below If the button event fires, it writes "EVENT FIRED" to the txtTestFired Textbox - suffice to say I have never seen that.
I am trying to display ImageButtons dynamically, which I have been able to do. I also want an event to fire when I click on those dynamic ImageButtons. I have the dynamic controls loaded in an ArrayList. I am able to have an event fire for all of the dynamic ImageButtons in the ArrayList except the first ImageButton in the ArrayList. Here is my code below (I tried to include only the relevant code):[code]
I have a form in a page that is popped up using the jquery dialog thus:using jquery ui 1.8.9 and jquery 1.4.4.[code] so this div dialogs up on a button click, but when i try to submit this popped up form with the clicking the butMove appointment just does nothing at all if i move it out of the popup it does fire is this because the popup doesnt simply show and centre the styled div?presumably i can get around this somehow?
I have a series of radio buttons in a Group Box on my main form. When I run the program, the first step is Sub New and the InitializeComponent() procedure.
It then immediately goes to the first radio button CheckedChanged event. This even currently contains some programming to access information from a database table. However, the program hasn't even gone through the process of opening the database and logging in. This doesn't happen until after my frmMain.Load event. However, this happens after the CheckedChanged event for some reason. So now that I have included the data requirement, I am getting errors because the reader is opening before the connection opens. I know I can set up a Try....Catch....End Try to avoid a user error, but ...I thought the form would have to load before anything about the controls happens and then since I haven't clicked anything, I am not sure why the event is triggering.
I have a problem with a Save button on a toolbar firing the click event twice if the user double clicks the button as opposed to single clicking.Disabling the double click on the toolbar itself seems to make no difference as it is the actual save button that is being clicked twice.I have tried setting a Boolean to stop the event firing twice but it is just too quick!I didn't have this problem with my code before as the server call was not async... and reverting back is not really an option.
My code is as follows:
Protected Sub tlbOrdQuot_ButonClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ToolBarButtonClickEventArgs) Handles tlbOrdQuot.ButtonClick
I have a asp grid with a few columns that bind to data. The last column has been converted to a template-field. In this template-field is a button with a modal popup extender attached to it. Hidden inside this field is a modal popup. This modal popup is used to add a new account. it contains 2 text boxes, drop down lists and buttons("Add" and "Cancel"). When "add" is clicked the modal should close after the inserting of the new account in the code behind.
The Problem: I get the popup to display and load the Drop down lists from the cache, without problem. How do I get the button click event to fire in the code behind. I've tried using a JavaScript function that performs a _doPostBack('btnAddAcc','') but it keeps returning the error "JavaScript error: Object expected". I gathered after about 1 hour on Google that it is because "btnAddAcc' is not found because it is actually within the grid-view cell and can't be directly accessed. Using page methods and ajax calls is a last resort as the company has a strict policy against this and only allowes this after a bunch of paperwork.
let's say I have a btnX_click event calling each time when I click btnX:[code] I have menuX menu item and click event for it:[code]I just want every time when menuX item clicked on to do the same thing as btnX control does when clicked.I haven't been programming in VB for ages;Actually haven't been programming at all for a while..But definitely remember writing (calling command event without explicitly clicking on it) this in Delphi; but cannot remember how;
It was pretty simple in VB6 to invoke the 'click' event of a command button (i.e.; btnNext_Click). I am having difficulty trying to do the same think in VS2008.
I am getting errors at line btnNext_Click(): Error1Argument not specified for parameter 'e' of 'Private Sub btnNext_Click(sender As Object, e As System.EventArgs)'.
Error2Argument not specified for parameter 'sender' of 'Private Sub btnNext_Click(sender As Object, e As System.EventArgs)'.
I am trying to write a program using Visual Basic 2008 Express Edition that will automaticlay generate multiple Command Buttons that have different Texts and perform different commands.For example I want to generate Button_1 and Button_2 where Button_1 when clicked enters the value "1" into a textbox and Button_2 enters the value "2" into the same textbox.I know this can be simple done by using the designer and wirting the code in the Button_1_Click, but what I want to eventually achieve is for various buttons to be generated across different Tabs in a TabControl.So far I can create a button on a windows form using code, but the button has no purpose so command is assigned to it. The code i've used is listed below:
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...
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 have a page which dynanically create a link when it load, after i click on the link it should loop in the database fetch all the record and display another set of link , then when i click on these link it should give me all information about this particular record it like this one
Q: when the page loads, it creates the first link which is associated with an event handler, it fire the first event handler (Getname) but it not firing the second event handler (GetnameDetails)
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init If ViewState.Item("nameload") IsNot Nothing Then If ViewState.Item("nameload").ToString = "True" Then
[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()
[Code]....
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 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.
I have a user control on which the button click event stopped firing even if I add a new button. It can be noted I'm using Telerik RadControls: RadButton specifically.
There's nothing special I'm doing to reference the elements: <telerik:RadButton ID="RadButton1" runat="server" Text="RadButton"> </telerik:RadButton>

I have a masterpage in which I attached a content page. Now, I added a button which is running at server and placed a code, MsgBox("hi"), in its click event. I placed a breakpoint in its click event and played it to see if it's firing and it clearly did not.
