如何将十进制格式应用于Gridview中的特定列？

例如，正在从SQL填充83.7837837837838，如何将其转换为83.8。

我只想将其应用于一列，因为其他列是整数，所以这不是必需的。

一种方法是使用DataFormatString属性。例如：

 <asp:GridView ID="GridView1" runat="server" 
    AutoGenerateColumns="False" 
    DataKeyNames="ProductID" DataSourceID="SqlDataSource1">
    <Columns>
        <asp:BoundField DataField="ListPrice" 
            HeaderText="ListPrice" 
            SortExpression="ListPrice"
            DataFormatString="{0:F1}" />
    </Columns>
</asp:GridView>

你也可以使用RowDataBound来控制你：

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
        // assuming you are using BoundFields and
        // the column which you want to format is the first
        // if you are using TemplateFields use e.Row.FindControl("ControlID") to find your controls
        var row = (DataRowView) e.Row.DataItem;
        decimal price = (decimal)row["ListPrice"];
        e.Row.Cells[0].Text = price.ToString("F1");
    }
}

编辑：这里是VB.NET版本：

Protected Sub GridView1_RowDataBound(sender As [Object], e As GridViewRowEventArgs) Handles GridView1.RowDataBound
    If e.Row.RowType = DataControlRowType.DataRow Then
        ' assuming you are using BoundFields and                                                   '
        ' the column which you want to format is the first                                         '
        ' if you are using TemplateFields use e.Row.FindControl("ControlID") to find your controls '
        Dim row = DirectCast(e.Row.DataItem, DataRowView)
        Dim price As Decimal = CDec(row("ListPrice"))
        e.Row.Cells(0).Text = price.ToString("F1")
    End If
End Sub
