If you have a textbox inside your grid probably you have multiple instances of it, with JQuery you can access all textboxes inside your grid like that :

function getTextBoxesInsideGrid()
{
    var gridClientID = '<%= grid.ClientID %>';
    jQuery.each($("#" + gridClientID + " input[type='text']"), function ()
    {
      var textValue = this.val();
      // do something
    });
}
