I tryied the following code, but doesn't work, still unformatted.

    <Columns>
        <asp:BoundField HeaderText="Valor" DataField="ValorProposta" DataFormatString="{0:c}" />
    </Columns>
</asp:GridView>

Answer 1

You have to set your HTMLEncode to False:

<Columns>
    <asp:BoundField HeaderText="Valor" DataField="ValorProposta" HtmlEncode="False" DataFormatString="{0:c}" />
</Columns>

MSDN: In versions of ASP.NET earlier than 3.5, you must set the HtmlEncode property to false in order to format fields that are not string data types. Otherwise, the field value is converted to a string by the default conversion method before the format string that is stored in the DataFormatString property is applied.

Answer 2

You can try setting the DataFormatString="{0:$#,##0.00;($#,##0.00);0}" and setting the HTMLEncoded = false.
