Question

I have a single columns table which holds 50 records. I would like to create 50 buttons from those records. How can I do that in Vb.Net?

Any help will be appreciated.

Assuming you mean Winforms:

Use your Datasource(f.e. a DataTable) and loop its RowCollection. For example:

Private Sub BtnLoadButtons_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnLoadButtons.Click
    Dim source As New DataTable("MyButtonTable")
    source.Columns.Add(New DataColumn("MyButtonColumn", GetType(String)))
    For i As Int32 = 1 To 50
        Dim newRow As DataRow = source.NewRow
        newRow("MyButtonColumn") = "Button_" & i
        source.Rows.Add(newRow)
    Next
    'you are loading the above DataTable from SQL-Server, now iterate the rows...'
    For Each row As DataRow In source.Rows
        Dim btn As New Button()
        btn.Name = DirectCast(row("MyButtonColumn"), String)
        btn.Text = btn.Name
        btn.Location = New Point(0, Me.Panel1.Controls.Count * btn.Height)
        AddHandler btn.Click, AddressOf handleButton
        Me.Panel1.Controls.Add(btn)
    Next
End Sub

Private Sub handleButton(ByVal sender As Object, ByVal e As EventArgs)
    Dim btn As Button = DirectCast(sender, Button)
    'do something ...'
End Sub
