Dynamically create ASPxButtons

I want to create a download list where each available file has its own ASPxButton and I would like to dynamically create them rather than creating like 30 manually and dynamically setting them to visible.

Since I don't have a form within my .aspx.cs file but create my buttons within a table in my .aspx code, I can't use the form.AddButton method. Any ideas on how to do something like that?

Not sure if that helps but here is the code for the 2 buttons I already have:

<dx:TabPage Name="Downloads" Text="Downloads" Enabled="false">
            <ContentCollection>
                <dx:ContentControl runat="server">
                    <table class="grid_centered">
                        <tr>
                            <td>
                                <dx:ASPxButton ID="btnDownload0" runat="server" Text="Anschreiben" Theme="Metropolis" CssClass="button centered" OnClick="btn_Click" Width="300px"></dx:ASPxButton>                                
                            </td>
                        </tr>
                        <tr>
                            <td>
                                <dx:ASPxButton ID="btnDownload1" runat="server" Text="Serie 1" Theme="Metropolis" CssClass="button centered" OnClick="btn_Click" Width="300px" Visible="false" Enabled="false"></dx:ASPxButton>
                            </td>
                        </tr>
                    </table>
                </dx:ContentControl>
            </ContentCollection>
        </dx:TabPage>

The solution to this is to use an asp:Repeater. This way, I only have to write the details for one and use the OnItemCommand event to handle button clicks. I had to switch to using asp:Button instead of dx:ASPxButton, though since I needed the CommandName field to pass the info which button was pressed along to my event handler.

<asp:Repeater
    ID="MyRepeater"
    runat="server"
    DataSourceID="MyDataSource"
    OnItemCommmand="MyClickedEventHandler">
    <ItemTemplate>
        <asp:Button
            ID="MyButton"
            runat="server"
            Text="Download"
            CommandName='<%# $"{Eval("keyField")}" %>' />
    </ItemTemplate>
</asp:Repeater>

I am not too familiar with dx:ASPxButton but I am assuming it would be similar to an aspx:Button. To dynamically create controls you have to create the controls in the Page_Load() event.

protected void Page_Load()
{
    //get your files
    string targetDirectory = "your directory";
    string [] fileEntries = Directory.GetFiles(targetDirectory);    
    int i = 0;
    foreach(string fileName in fileEntries)
    {
        ASPxButton btn = new Button();
        btn.Text = fileName;
        btn.ID = "btnDownload" + i.ToString();
        btn.CssClass = "button centered";
        btn.Attributes.Add("Theme", "Metropolis");
        //add any other properties you need

        //add the event handler
        btn.Click += new EvenHandler(btn_Clik);
        form.AddButton(btn);
    }

}
