how to create dynamic button array in Asp.net?

The Best way to use Dynamic Buttons is DataList Make a DataList with item template containing a Button element. Bind the datalist with dataSource of buttons data collection. As

<asp:datalist id="dlButtons" runat="Server" onitemcommand="dlButtons_Command" xmlns:asp="#unknown">
      <itemtemplate>
              <asp:button id="cmdSubmit" text='<%#   Eval( "Text" ) %>' runat="server" commandname='<%# Eval("Command") %>' />
      </itemtemplate>

Now Handling on server Side on Page Load Event just bind the data source with Data List like As

 List<Button> buttons = new List<Button>();
 Button b1=new Button();
 b1.Text="Previous";
 b1.Command="Prev";
 buttons.Add(b1);

 Button b2=new Button();
 b2.Text="Next";
 b2.Command="Next";
 buttons.Add(b2);

dlButtons.DataSource=buttons;
dlButtons.DataBind();

Now You can Write Button Action Code here

 private void dlButtons_Command(object sender , DataListCommandEventArgs e)
{
       if(e.Command == "Prev")
       {
             //Write your code here
       }
      if(e.Command == "Next")
      {
             //Write Your Code here
      }
}
