[英]How to change the format of a column in GridView from c#
I have a GridView and I want to export it to Word. 我有一个GridView,我想将其导出到Word。 I want to change the format of one column to datetime format ("dd.MM.yyyy")
我想将一列的格式更改为datetime格式(“dd.MM.yyyy”)
var grid = new GridView { DataSource = dt};
grid.DataBind();
In *.aspx page this is very easy, it looks like in the example below: 在* .aspx页面中,这非常简单,如下例所示:
<asp:boundfield datafield="My_Date_Column"
dataformatstring="{0:dd.MM.yyyy}"
htmlencode="false" />
I want change format from c#, how to do this? 我想从c#改变格式,怎么做?
If you want to alter the format of a column of a GridView from CodeBehind Add a RowDataBound
to your grid view. 如果要从CodeBehind中更改GridView列的格式,请将
RowDataBound
添加到网格视图中。
Then in the GridView_RowDataBound(object sender, GridViewRowEventArgs e)
method, you'll be able to access e
which will provide you with access to the individual cells of that row where you can specify a formatter. 然后在
GridView_RowDataBound(object sender, GridViewRowEventArgs e)
方法中,您将能够访问e
,这将使您可以访问该行的各个单元格,您可以在其中指定格式化程序。
Here's an example of using the RowDataBound
event http://forums.asp.net/p/1589807/4025153.aspx 以下是使用
RowDataBound
事件的示例http://forums.asp.net/p/1589807/4025153.aspx
String.Format("{0:dd.MM.yyyy}", myDateTimeInstance);
I think the format of column is based in system current date time format. 我认为列的格式基于系统当前日期时间格式。
But when converting to string you can do so 但是当转换为字符串时,你可以这样做
String str = dt[RowNumber][ColumnName].ToString("dd.MM.yyyy");
DateTime dt = DateTime.Now;
String formated = dt.ToString("dd.MM.yyyy");
OR 要么
String formated = String.Format("{0:dd.MM.yyyy}", dt );
DateTime dt = DateTime.Now;
string formated = dt.ToString("dd.MM.yyyy");
Possible formats are shown in this MSDN article . 可能的格式显示在此MSDN文章中 。
In case you want to format the entire column then it would be better if you can set the property for your concerned column 如果您想格式化整个列,那么最好是为相关列设置属性
gridview1.Columns[columnIndex].DataFormatString ="{0:dd.MM.yyyy}";
I think you will need to cast the column as BoundField
to access the property. 我认为您需要将列
BoundField
为BoundField
才能访问该属性。
