When the user selects an "account" we dynamically create a linkbutton with the selected dates. However, the linkbutton onclick handler doesn't fire when the button is clicked.
Dim linkBtn As New LinkButton
linkBtn.Text = "----"
AddHandler linkBtn.Click, AddressOf linkButtonHandler
linkBtn.ID = panelDatesRencontre.Controls.OfType(Of LinkButton).Count
panelDatesRencontre.Controls.Add(linkBtn)
[Code] .....
I make that in page_load, it seems to work.

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
End Sub

I have a TableGridLayout (6 x 6) which host 36 buttons created at design time.From the 36 buttons, only a handfull maybe needed at anyone time depending on data retrieved from an SQL database.Everytime I need to 'clear' the grid to populate with new items, I clear the text of each button, make it visable if required and then upadate with the new text.On every pass if a button becomes active, I add an event handler to the button like this.[code]...

I 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?

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
[code]....

I 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?

What is an "EASI" LinkButton? Why don't you just use an ASP.NET LinkButton? Try modifying your JavaScript method so that it returns "true" if you want the postback to occur...and "false" if you want it to stop. Then change the LinkButton to so that it "returns" the value that is returned by the JavaScript method... This should stop the postback from occurring (but then again I've nevers een an EASI LinkButton before.......)
<EASI:LinkButton ID="btnSearch" runat="server" CausesValidation="False" ClientScript="return confirmSearchOK();"UseSecurityLevel="True">Search</EASI:LinkButton> JavaScript modification suggestion:
function confirmSearchOK() { var planSel = document.getElementById("<%= ddlPlanID.ClientID %>").selectedIndex;

Basically, I have about 5 forms. 1 of these forms is the main program screen. I need to be able to use select case to navigate to the other forms, however I am unsure how to do this. I thought about using multiple buttons to each form using select case, but did not know how to implement this with the click event handlers for each button?

I have 2 listboxes on a form. Each listbox has a few items. As you know, I am able to have 1 item selected from each listbox, therefore making it 2 selected items from different listboxes.
I want to create a keyboard + mouse shortcut so I can de-select or change the selection mode of the listbox when Alt is held down and Left button on the mouse is clicked on the selected item. Here is the code that I wrote, which does not work.
Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown
If Control.ModifierKeys = Keys.Alt AndAlso e.Button =

The event handlers in my parent class are never called though the events are raised in the child class.
The Code:

Private Sub checkboxchanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged, CheckBox2.CheckedChanged

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??)

Reading about VB .NET I found out that now it is possible to handle more than one control with the same event handler. What I want is to specify what my Radio buttons will have to do, using a single sub instead of using a sub for each of them. However I am still far from achieving that. I am using something like that:
Private Sub ForAllRadioButtons_CheckedChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged, RadioButton2.CheckedChanged, RadioButton3.CheckedChanged
If sender.name = RadioButton1 Then
Code 1 ...
ElseIf sender.name = RadioButton2 Then
Code 2 ...
ElseIf sender.name = RadioButton3 Then
Code 3 ...
End If
End Sub
However, I get an error message which says :
Operator '=' is not defined for types 'Object' and 'System.Windows.Forms.RadioButton'.
I bet 100 $ that it's something that I don't do it right . Unfortunately I can't get that money. Would it be the same if use the Click event instead of the CheckedChanged ?

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
