Event Of Dynamically Created Control Not Firing?
Jul 1, 2011I'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, 2012I 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

Event Handler For Dynamically Created Controls?
Mar 4, 2012I would like to ask a question with DataGridView event handling.The event I am going to handle is the double-clicking of a cell in a DataGridView:If the DataGridView's are statically drawn on the form at design time, then it is easy to assign to each of them an even handler by double clicking the corresponding event in the properties panel.
Private
SubDataGridView1_CellDoubleClick(sender
AsSystem.Object,
[code]....
So basically I have handle to all of the DataGridView's. Is there a way to create a common event handler on this basis?
Event Handlers For Dynamically Created Controls
Aug 2, 2009I'm not seeing anything about event handlers for dynamically created controls.. and I could have sworn I had once before. I did see one post about the topic, but it was just replied by asking for some posted code, so as in a preemptive move..
Private Sub buttonCreate()
Dim newbutton As New Button
newbutton.Height = 39
[CODE]...
Here's what I'm trying...
Private Sub newButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles newButton.Click
End Sub
Here's the errors I recieve...QuoteHandles clause requires a WithEvents variable defined in the containing type or one of its base types

Apr 21, 2009I have a website where the user requires to add and remove Headlines from the main page.
The headlines are stored in a database with a column titled 'Display' (true or false) which decides if the headlines appear.

VS 2010 : Event Handler For Dynamically Created Controls?
Sep 14, 2011I have to create controls for inputting info to create people objects in the program, because I don't know how many people they are going to input, I have a button that they can press to add more fields.
I need to add a doubleclick event for these dynamic controls (text boxes), how can I create an event for them if they haven't been created yet. Also, as far as I know you cant make a variable part of an object name while declaring it. I need to do something like
Dim dynamicText & (Append variable counter each time a box is made)As New TextBox
dynamicText &variable counter. Name = "TimeTextBox"
dynamicText.Text = "SdgsdG"
dynamicText.Location = New System.Drawing.Point(100, 100)
[code].....
Also is there a way to like copy and paste a group of controls via code instead of having to code each individual one like if I had to do a text box along with a combo box and a lable all at once, can I throw it into something so I only have to recreate the container?
Access Objects On A Dynamically Created UserControl An A Dynamically Created Tab Page?
Dec 5, 2011I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!

Get Around Non-exposed MouseClick Event?
Apr 28, 2009I have an ActiveX component (for mapping) I am using that I need to do an action on a mouse click, but the event isn't exposed. Internally, the class seems to fire an event, as it has a LastPointClicked() method that you can call that returns the map coordinates of the last point you clicked on. I am trying to find a way to center the map on the point clicked. I could fudge it with some kind of timer that just checks to see if the LastPointClicked has changed and center if it did,

Which Tab Was Clicked On Tabcontrol MouseClick Event
Feb 12, 2010I am learning how to develop Windows Forms applications with Visual Basic Express 2008, and my testing/learning application has a TabControl with a few test pages (3, for example, the number isn't relevant here).Now, I am handing the MouseClick event on the Tabcontrol, and I can't seem to be able to figure out how to get which tab was clicked on.I believe that the MouseClick event isn't fired if I click on another place of the tab strip, therefore a tab must have been clicked on. The problem is, which was the tab?

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.
