Asp.net - Double-clicking On A Form Control In VB 2010 Design View Inserts A Script Instead Of Inserting An Event Handler?
May 8, 2012
When I double click on a form control while in the design view in a Web Application project within Visual Studio 2010, say a 'button' or a 'submit' for example, it inserts a javascript function into my .aspx file. When I do this at work it automatically creates an event handler for the control in the code-behind.How do I change this to that setting?I don't want to type those event handler subroutines every time!

The title pretty much precisely asks the question, but I shall repeat;
When I double click on a form control while in the design view in a Web Application project within Visual Studio 2010, say a 'button' or a 'submit' for example, it inserts a javascript function into my .aspx file. When I do this at work it automatically creates an event handler for the control in the code-behind.How do I change this to that setting? I have used '/resetsettings' already, and other answers to similar questions do not solve my problem. I have reinstalled, gone through every menu I can find (though I may have missed something)I don't want to type those event handler subroutines every time!

I am trying to learn Visual Basic and am working through a text book that my son used for a class. Each time I create an event handler by double clicking on the design page, the code that automatically populates is almost identical to the code in the book, except the byval portion is omitted from the code.[code]

After inserting an user control and double clicking on it, a stub with the default event should appear.
If I don't define what the default event is and I don't assign any attributes to any events or properties, it works, and it generates the stub for the UserControl.Load event (the default default event).
But if I set some attributes for the properties and events and/or I define the default event, the stub generated is corrupted. Here is an example of what I should get:
Private Sub FaceSelector_OnSelect(SelectedObjects As System.Collections.ObjectModel.Collection(Of Object)) Handles FaceSelector.OnSelect
End Sub
And this is what I actually get: Private Sub SketchSelector_OnSelect( SelectedObjects As System.Collections.ObjectModel.Collection`1)
End Sub
Private Sub FaceSelector_OnSelect( SelectedObjects As System.Collections.ObjectModel.Collection`1)
End Sub
In this case I had 5 user controls, I double clicked on one of them, and I got 2 corrupted stubs.
Sometimes the corrupted stubs are generated when I change some properties of other controls in the form, or the form itself. For example I resize the form, the error window doesn't show any errors, hit F5 to compile and run, and get a syntax error.
I tried to track the problem down by removing each event/property attribute/xml description, one by one, many times I thought I found the culprit, but after 10 minutes the problem popped up again.

I am playing around with Drag and Drop, and I am having an issue with AddHandler. I am creating labels and displaying them on a form. Before I add each label to the form, I add 2 event handlers (DragEnter and DragLeave). When I run the code, it hits the first event handler (DragEnter), but doesn't hit the second event handler (DragLeave). Either I have coded something wrong, or the second handler is not being added.
Here is my code (note this is just something Im playing around with for learning):
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code]....

If I have a panel with a handful of controls in it, and I want to create a click event for anytime that the user clicks on any controls that are NOT inside that particular panel, how would I do it? In other words, if there was an event called "ClickSomethingElse", that would be perfect. Any way to accomplish something like this? I realize that I could create individual click events for each of the controls outside of the panel, but there are a LOT of controls outside of the panel, so I was just wondering if there is a more efficient way to do this.

Is there a shortcut to get to the designview form in a winforms project in visual studio 2010.F7 will take you to code behind class form and shift + F7 will take you to design mode. Is there a shortcut to filename.designer.cs formWhere you have the control definitions, delegates (for click event etc). defined. I go to the form often if I change the name of click event etc.I have to go through solution explorer and click on the file. Is there a shortcut like F7 that opens the designer.cs file?

I have a login page, which a user will have to enter username, password and accesslevel. Accesslevel is either 1 or 2. 1 for admin and 2 for users who are restricted from using certain functions. I have this module set up so that I can make use of the accesslevel throughout the forms that I have.
Module ModuleAccessLevel
Public AccessLevel As Integer
End Module
Arjun taught me how to make use of this module, so now I know how to restrict users from using certain buttons, toolstrips by doing the following:

I seem to have reached a limit on the size of the form. I cannot make the form longer and I need to add more fields. Is there a limit on how many fields can be included in a form?

i have been working on an app, that remains just my preset sizes. recently, i have discovered that by double clicking the form title bar, even w/the formborderstyle being set to fixedtoolwindow, the form still maximizes and all of my controls remain in the top/left corner.. not a good view.. so, i set the maximum size of the form, and now when double clicking it, moves it to the top/left of my desktop.. not a good result. here is a quick sample to start w/.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
how do i permanently block the double click on the title bar, to have no effect on the form? i do not want to end up w/having to create a borderless form just to avoid this..

I didn't get the result I want from the following code:
Private Sub tblView_SelectionChanged(ByVal sender As System.oject, ByVal e as System.EventArgs)Handles tblView.SelectionChanged
Dim st As String = tblView.SelectedRows.ToString
[Code]....
I wanted the data I selected on the datagridview row to be display in the textbox, but it displays the error message that st(0) produces "S" which is incompatible to my RackID data type.

The event handlers in my parent class are never called though the events are raised in the child class.
The Code:
Public Class childForm
Public Event checkboxchangedEvent(ByVal checkbox1 As Boolean, ByVal checkbox2 As Boolean)
Private Sub checkboxchanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged, CheckBox2.CheckedChanged

I create a dynamic number of PictureBox controls. I keep them inside a List. What I want now is to make them clickable: same event handler for all (opening of the image source file) with a parameter. The question is: how can I do it in practice? How I set the handler Sub for every picbox?

I have a piece of code that i want many ListViews to run throughout the app at ItemUpdated. I'm sure the same can apply to many other control-events.How can I hook up a certain listviews ItemUpdated event to a sub in a class module?
here's my class module Public Class ControlParts
Public Shared Sub LSVItemUpdated(ByVal sender As Object, ByVal e As ListViewUpdatedEventArgs)
Dim lsv As ListView = CType(sender, ListView)
lsv.EditIndex = -1
End Sub
End Class
Now if i add OnItemUpdated="LSVItemUpdated" to my ListView's declaration I get an error that 'LSVItemUpdated' is not a member of 'ASP.admin_order_aspx'. Well, I don't want this on the page. I wan't this to be globaly accessible. I could in the code behind call the LSVItemUpdated, but that will beat the whole point off.

I was loading my project when my computer rebooted suddenly. After it came back up, I went to load my project again and got an error about "an error occured when loading in the design view..this has been disabled" - sorry I did not get the exact message but it was something like this. Then when my project opened up, I now cannot see my form in the design view anymore. It still run's fine, but there is no code displayed and the form itself does not display in IDE anymore. I can see the code for the form only on the form.designer.vb mode.I have continues backup installed, and restored several versions of the class files for the form, but yet still no luck.

When you click on a button control on a web form visual studio automatically put in this code for you in the code behind.
Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnFlightInfo.Click
end Sub
Say for example, I wanted to call this method from another method. How would I do that? I know that the sender is the actual button object, but what is e? Here is what I have so far inside another sub. Just trying to get a better understanding of how this method works.
btnSave_Click(btnSave, ??what would you put there??)

I am using VB2010 Express to create a Windows Form.
I have been able to add an event handler to a single textbox to respond to the ".Leave" action.
Now I want to take multiple textboxes and use them as a single control and use the same event handler.
Eg. If TextBox1, TextBox2 and TextBox3 are grouped as a single control nothing would happen in those boxes until focus went to any other control on the form.

During the process of my program I am creating several different buttons depending on what file the user selects. I have been able to create these buttons and I would like to set up the event handler so when the user selects one of these buttons it pops up a message box that shows the user the name of the button they just clicked on. The message box isn't the goal of what I would like to do with it but If I could get that to work I would be able to alter the code to get it to work the way I want it to.
Below is my code that I currently have. I don't have the event handler doing anything at this time as I can't seem to get it to work I am still playing around with it.
ublic Sub resizebuttons()
Dim X As Integer = 175
For Each item As String In CSVInput.selected

I am creating an application for a college assignment called "Quote Manager" - the idea is a writer can save his / her favourite quotes, then go back to them and be able to print them.So I had this idea where all the quotes are loaded into a datagrid view on the main screen of the program and the user can double click on the quote he / she wants to load.
I don't want any code given I would also post what I have got so far but at the moment I am at work.What I want is to know how to manipultate the datagridview control so when a cell is double clicked a saved html page will load from a database.

i'm on day one with VB05 express Beta 2 after a several-year break from VB6 after having a sudden surge of programming inspiration. i must say i'm quite impressed with a lot of the features, however, i'm really stumped by something that must be so simple that i'm just looking too hard or something.i've been looking for hours at how to return to the graphic design view of a form. i can't find it anywhere. all of the code from when i closed my project is still there but the visual representation of the form itself is nowhere to be found.

I often get this problem. I open a form in design mode and the form is not in view and scrollers can't get to it. Sometimes it's cut in half and the other half is outside the window but there's no way to move the form inside the design space to see the form in full. Sounds like a lame problem but I can't find a way to properly open the form

I'm creating an ASP.NET Custom Control for my web application which is basically an ASP.NET Button control contained inside multiple <div> elements (for styling purposes).How can I create a Click event handler for my custom control so that my control acts as an ASP.NET Button?
Ie.
<cc:Button id="myButton" runat="server" Text="Submit" />
Sub myButton_Click(sender as object, e as EventArgs) Handles myButton.Click
