Búsquedas mas claras

Código publicado en el Blog del filipino Jun Tangunan con el cual podemos realizar búsquedas mas claras en nuestras grillas.

A medida que escribimos un texto para buscar, se filtra y se colorea el texto coincidente en los cada registro de la grilla. Este efecto se logra con las propiedades DynamicForeColor y DynamicFontBold de cada columna
