[英]How do I store a set of SqlCommands and apply or discard them on form close in vb.net?
[英]VB.NET How do I apply decimal formatting to a specific column in a Gridview?
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
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:这里的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
您只需要使用BoundField.DataFormatString属性,为了解决您的问题并获得适当的知识,请检查此Microsoft链接
