ABRIR JANELA POPUP

Crie uma Lib:

unit uLib;

interface

uses System.Web.UI, System.Web.UI.WebControls, System.Web.UI.HtmlControls, System.Text,
System.Configuration, System.Web.Security;

{: habilita e desabilita controles }
procedure EnableDisableControls (aControls: ControlCollection; aValue: Boolean);
{: limpa controles de tela }
procedure ClearControls (aControls: ControlCollection);
{: abre uma nova janela no browser }
procedure OpenWindow (aPage: System.Web.UI.Page; aRedirect, aWidth, aHeight: string);
{: executa um script do JavaScript }
procedure ExecuteScript (aPage: System.Web.UI.Page; aScript: string);
{: mensagem com JavaScript }
procedure MessageScript(aPage: System.Web.UI.Page; aTexto: string);

implementation

procedure OpenWindow (aPage: System.Web.UI.Page; aRedirect, aWidth, aHeight: string);
var

end.


No botão insira isso:
procedure TWebForm1.Button2_Click(sender: System.Object; e: System.EventArgs);
begin
OpenWindow(Page, ´pesquisaFuncionario.aspx´, ´500´, ´300´);
end;

ou...

simplesmente use um JavaScript, window.open... 8)
