VS 2008 - Dynamically Direct Control Event To Use Predefined Method

Nov 15, 2009

Is it possible to dynamically direct a particular control's event to use a predefined method. For example: I have a form which I dynamically add controls to, let's say, TextBox1, TextBox2 and extBox3 and a module which as 3 routines, Method1, Method2, Method3. When I dynamically add my controls, eg TextBox4, I want to choose which of the 3 methods I want mapped to which event.

I was thinking of something like this...
Dim objTextBox1 as new TextBox
dim NameOfRoutine$="Module.Method2"
Form.Controls.Add(objTextBox1)
Call AssignMethodToEvent(objTextBox1.GotFocus, NameOfRoutine$)

Dynamically Entering Values In A Predefined Email Body In Mvc 3?

Oct 11, 2011

I am writing a mvc 3 application and part of its function is to send out confirmation emails along with an assortment of other emails.. I have the body's for the different types of emails stored in a database table.. Getting the values out of the table and dropping them in a email body using System.Net.Mail isnt a problem at all... What I need to do is somehow put somekind of variable marker in the body which is in the database table and then somehow parse the body text when its dropped into the email body to find the variable marker and put the correct value in it's spot..Code snippet of what I have so far is below:

Keep in mind that this will be a rather large body and there are a few places values will have to be dropped in.. I was thinking of having it use something like this:

Long mail body ^^Name^^ has been approved for classes starting on ^^Date^^ at the ^^Place^^ located in ^^Location^^..

When the code loades the text from the body when ever it comes across a variable marked with ^^ it would put the correct information in its place...

Dim _content As email = db.emails.Where(Function(f) f.ref_name = "Confirmation")
Dim _body As String = _content.email_body.ToString
Dim SmtpServer As New SmtpClient()

Event Not Firing On Dynamically Added Control

Nov 19, 2010

I'm adding multiple combobox controls to a form dynamically, but am having a problem with one of the event handlers. The first event handler I've added (for the Leave event) fires, but the second (for the TextChanged event) does not. I've tried reversing the order when adding the handlers and I get the same results (TextChanged does not fire). Here's a code snippet for adding the controls, and the code for the events. I've added a breakpoint while testing to verify - but it never hits the code.

Dim cbo As New ComboBox
cbo.Name = "cbo" & fldName
cbo.Tag = fldName.ToUpper
cbo.Top = rowtop
cbo.TabIndex = tabOrder
cbo.DropDownStyle = ComboBoxStyle.DropDown

Event Of Dynamically Created Control Not Firing?

I'm having a problem with a Web Control that is dynamically created and inserted in my page. I create a couple of LinkButtons, depending on the data of the search that was made, and I'm trying to add an Event Handler to each of the Buttons, so it would filter the result. The controls are initialized properly, but the event is never fired.

Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init

Event Handler For Dynamically Created Listbox Control?

Jan 24, 2012

I am passing some values from a Gridview Update Click event to a popup ASP.net page that dynamically builds a series of textboxes in a Placeholder based on the number of sentences that are found in a specific cell of the Grid Row selected.The boxes that are built represent each sentence found in the cell of the selected row. Each sentence is presented for translation, where user enters data into a 2nd dynamically generated textbox.This all works great.Now I have a Listbox beside the 2nd textbox, which sometimes has 1 or more variables that need to placed into the translated sentence. I have set up a Hover menu over the listbox so that I can select the variable and insert it at the end of the sentence in the 2nd textbox. My problem is generating the click event on the dynamically created Listbox. Something like....

Protected Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
TextBox1.Text = TextBox1.Text & ListBox1.SelectedValue

Button Control Event Handler Method

Apr 20, 2012

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??)

VS 2008 Adding A New Method To A Custom Control Found

Feb 25, 2010

I found a custom ListBox that, strangely doesn't have an InsertAt method and I would like to add one. The custom ListBox uses an object instead of just a list of strings like a normal ListBox. I was curious what the logic behind inserting a new item at a particular index would be.The only thing I could come up with was add the new ListBoxItem at the end, then using the specified index, I could either keep moving ListBoxItem objects to the bottom, with the Add() method, from that index till the ListBoxItem at that index equals the one added, or I could use that index number in a "calculation" till I know I've moved the correct number of objects.

C# - Dynamically Get A Particular Method's Name In A Strongly Typed Way?

Apr 7, 2009

I'm looking for a the shortest/aseist way in VB.NET (or C# but using VB.NET at the moment) to get the string value of a method's name dynamically given the method call.For instance, I have a class like this:

Public Class Blah
Public Sub Foo()
End Sub
End Class

Now Foo is a strongly-typed cover for a dynamic setting and I have an event handler that will fire when the setting changes and return the string name of the setting that changed.

I'd like to be able to switch/select on this string and have a case based on the Foo() method. To do this I need to able to get the string name of the Foo method from the method call itself (i.e. somehow GetMethodName(blahInstance.Foo())).

Control Array - Add New Event - Click Event Code And Calling It A Doubleclick Event

Jul 31, 2010

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

Heres the tutorial with my new code encased in asterisks ...

Dynamically Remove Method Calls At Runtime?

Jan 24, 2011

What's the best way to dynamically remove method calls at runtime? Essentially what I'd like to do is pass a parameter to my application. Let's call the parameter level. Depending on the value of level, I'd like to essentially remove all the calls that have higher levels. I have the following but was wondering if there were a simpler/cleaner way to remove the calls:

Ideally I'd really like to write something like:

Log5("message")

And just have Log5 work or not call if it doesn't exist. My goal is to actually remove the call. The overhead for calling level 5 logs that test and return is fairly high and I rarely use it.

Module Module1
Delegate Sub Log(ByVal message As String)
Public Log1 As Log = Nothing
Public Log2 As Log = Nothing
