[K.Babu]

Hi,

I want to create hyperlink button at run time in Vb.Net->asp.net web application. eg. mywebapp.aspx.vb (VB coding)


I want to create hyperlink button through by vb coding, not by asp code.

Thanks a lot,
K.Babu

Private sub DoSomething()
        '
        'Create control
        '
        Dim lbDemo As New LinkButton
        '
        'Modify properties
        '
        lbDemo.Text = "Click me!"
        lbDemo.Visible = True
        '
        'Add a handler for the click event
        '
        AddHandler lbDemo.Click, AddressOf LinkButton_Clicked
        '
        'Add the new control to the page, panel, placeholder, whatever...
        '
        Page.Controls.Add(lbDemo)
End Sub

    Private Sub LinkButton_Clicked(ByVal sender As Object, ByVal e As System.EventArgs)
        '
        'Gets called when our custom linkbutton is clicked
        '
    End Sub

FYI: A LinkButton must be inside of a Form where Runat=Server.

Yes... again, it has to be inside of a FORM where RUNAT=SERVER.

I've attached an example that shows one method to place a control in the middle of a FORM.
