Private Vs Protected - Button Click Event Is Created In ASP.NET ?
Feb 22, 2012
In ASP.NET using VB.NET, you can define the wired up button click event (to an ASP.NET server control) in 2 different ways (for the purpose of this conversation - manually wiring up via button property not in question here):
Double click on the button in the designer which produces an event in the code behind with a Protected method.In the code behind, select the button from the list of controls, and then select it's 'Click' event. This produces a Private method.I understand the difference between Private and Protected; why based on how the wired up event is autocreated it generates a different Access Level on the method?
I'm writting a program that will output the column headings of the database onto a form in a label along with a text box for the user to input their own information and a button to add a new record in the database. My problem is I do not know how to refer to the text boxes or how to call the click event from the button that was created at runtime.
if for example i have two private sub I declared a local variable on private sub a... is there a way that private sub b could use the variable created on private sub a? Im asking because im in a problem in my app were using global variable is not an option to make the long story short
I created a button control ,, by double clicking only the process was going on,,when iam single click the button nothing is to be happenend,,so i want to change into single click insted of double click........here my coding is given below.......
I have two forms. Form 1 you click a button, and it opens Form 2. Form 1 is still open.
When you click a button on Form 2, I want to run a Private Sub that is on Form 1, whilst Form 1 is still open.
The idea is that the data i've entered on Form 2, once I close this form, I can continue working with Form 1 with the updated data without having to close and re-open it.
I have created a program that allows the user to click on screen and add many ovalshape objects. But I have got stuck as now I need to create a rightclick event for any of the runtime generated ovalshapes on screen and dont know how to refer the right click event to all the many objects?
My code for creating the oval's are as follows:- Dim Drg As New ShapeContainer Dim Shape As New OvalShape Drg.Parent = Me Shape.Parent = Drg Shape.Size = New System.Drawing.Size(10, 10) Shape.FillColor = StampColor Shape.FillStyle = FillStyle.Solid
But how do I write a click event now for any of these runtime created objects???
I'd like to have a Private or Protected "Setter" for a property that also happens to be an abstract (MustOverride). I'm porting some code from C# to VB and in C# this is pretty straight forward. In VB not so much (for me anyway).
Some code...
In C#... public abstract class BaseClassWithAnAbstractProperty { public abstract int AnAbstractIntegerProperty { get; protected set; } }
[Code]....
The issue seems to be the inability to flesh-out the Get/Set specifics in the declaration.
How can you add a click event to dynamically created menu item?I thought I could do something like
Loop through all the items in the Menu1.DropDownItems then create a mousedown even on the item and execute an action based off that.I'm new to VB and was wondering what logic to use. Will that even work? How will the events be saved through the life of the application?
What purpose do protected or private (non-static) events in .NET really serve?It seems like any private or protected event is more easily handled via a virtual method. I can (somewhat) see the need for this in static events, but not for normal events. Have you had a use case before that clearly demonstrates a need or advantage for a non-static protected or private event?
i'm making some login function with some website but this website button is some different before what i know method. to login this website , first should have to some button click then drop down menu go down then can input id and password. how can i emulate click and make drop down this menu? if you go following website you can see right side 'Log in' button if click this button drop down menu go down [Code]
I have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.
I want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:
Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)
My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.
In my application, I want to have 10 webbrowsers, which go to google like this. For i = 0 To 9 Dim Browser As New WebBrowser Browser.Name = "Browser" & [i] Browser.Navigate("[URL]") Browser.Visible = True Next
So now I will have 10 webbrowsers aimed for google, right? So how do I make a loop that clicks the search button 10 times? I know I need to use member_invoke like this Browser.Document.GetElementById("search").InvokeMember("click") But I have no clue how to code the loop.
I created a button in DatarGrid. Now I want to click that button and only when I click the button should the event be fired. Actually I want to Delete that particular row once the button is clicked. However, when I click the button, the Event: CellContentClick of the DataGrid gets fired. And that means if you click anywhere on the Datagrid, that even will be fired, and that makes no sense to put a Delete button. So I want to keep the Delete button and once the Delete button event gets fired, the record gets deleted.
Which always calls a method with no params or return. The idea is that the user of my object (transactional processing of business logic) inherits the base class adds in a load of private methods to fire. They then add these method names to a list in the order they would like them fired and the code above will take care of firing them.
It works fine with public methods but not with private or protected methods in the same class (Protected because I have some 'standard' pre built methods to add to the base class). Realistically I could make the methods public and be done with it but my inner nerd wont allow me to do so...
I am assuming this is a security feature. Is there a way to get around this or does anyone have any suggestions on how to proceed but keep my tasty, tasty visibility modifiers in tact?
(NOTE: ITS IN VB.NET but a C# Answer is fine if that is what you are comfortable with).
Dim NewButton As New Button frmDownload.Controls.Add(NewButton )
This works. But I want to change what happens upon clicking NewButton. It should start an application. I tried NewButton.Click but that event doesn't exist.
I believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.
I have created a custom control that has a few labels and a button on it. In my main program i dyanmically add this control to a stackpanel. When i add the control i add a few events for it by doing th e following:
Dim newqueue As New UserControl1 AddHandler newqueue.MouseDoubleClick, AddressOf PrintMessage
How would i go about adding an event for the button.click for the button in the custom control?
i want to call a button click event in any other event like this form key down event.if e.control andalso e.keycode=keys.S then savebuttonclick event should be called end if
i have two asp:buttons.. say button1 and button2, what i would like to do is fire button2's click event when I click button1.. is there a way to trigger click event on an asp:button through code behind? please help, newbie here.
I have a form that I am adding a set of buttons to. I am adding an event to those buttons. I need this event to function slightly to determine what button was pressed.
I need the button to simply set a string variable equal to the clicked buttons text so I can determine what button was pressed.
How can this be accomplished?
''Adding the buttons'' For Each dr In dtMenus Dim strMenuName As String strMenuName = dr.Item("strMenuName").ToString
I placed cursor over the button and press left mouse.Ok i know how to use button_click event..BUT how do you make the button_click event continuously fire while the mouse left button is kept down over the button on the form. with a custom set interval say of 500ms
