A dynamically added button makes post back to login page












0














In order to Add dynamically a Button I use the following code inside the LoginButton_Click sub



Dim ModeratorButton As New Button
AddHandler ModeratorButton.Click,
AddressOf Me.ModeratorButton_Click
With ModeratorButton
.ID = "ModeratorButton"
.Attributes("OnClientClick") = "ModeratorButton_Click"
.CssClass = "ModeratorButton"
.Text = "Ενημέρωση"
End With
MessagesPanel.Controls.Add(ModeratorButton)


I also have a protected sub in order to handle the event



 Private Sub ModeratorButton_Click(ByVal sender As Object, ByVal e As EventArgs)

End Sub


As a result of all these I receive the normal page

With the Panel I want and the controls I need in it.

The issue starts when I push the ModeratorButton and the code never goes to the protected sub I mention earlier

Instead of that it makes a post back to the LoginPage



Is someone to assist me on this?

After postback you need to AddHandler again.



For example, like this.



Private Sub _Default_Load(sender As Object, e As EventArgs) Handles Me.Load
If Request.Form("LoginButton") IsNot Nothing Or
Request.Form("ModeratorButton") IsNot Nothing Then
Dim ModeratorButton As New Button
With ModeratorButton
.ID = "ModeratorButton"
.Attributes("OnClientClick") = "ModeratorButton_Click"
.CssClass = "ModeratorButton"
.Text = "Ενημέρωση"
End With
AddHandler ModeratorButton.Click, AddressOf Me.ModeratorButton_Click
MessagesPanel.Controls.Add(ModeratorButton)
End If
End Sub

Private Sub ModeratorButton_Click(sender As Object, e As EventArgs)

End Sub


https://support.microsoft.com/en-us/help/317794/how-to-dynamically-create-controls-in-asp-net-by-using-visual-c-net




Note When you create dynamic controls on a Web Form, the controls must be created and added to the controls collection either in the OnInit or in the Page_Load events. Otherwise, the controls behave unexpectedly.
