How to change the format of a column in GridView from c#

Question

I have a GridView and I want to export it to Word. I want to change the format of one column to datetime format ("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:

<asp:boundfield datafield="My_Date_Column"
                dataformatstring="{0:dd.MM.yyyy}"
                htmlencode="false" />

I want change format from c#, how to do this?

If you want to alter the format of a column of a GridView from CodeBehind Add a RowDataBound to your grid view.

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.

Here's an example of using the RowDataBound event http://forums.asp.net/p/1589807/4025153.aspx

that's the easy bit. how would he get access to that datetime from the code behind if its bound in the grid. – Eoin Campbell May 21 '12 at 08:02
@EoinCampbell: Cast grid source as Datatable. and use like `dt[0]["columnname"].ToString("dd.MM.yyyy");` – Nikhil Agrawal May 21 '12 at 08:45

I think the format of column is based in system current date time format.

But when converting to string you can do so

String str = dt[RowNumber][ColumnName].ToString("dd.MM.yyyy");

DateTime dt = DateTime.Now;
String formated = dt.ToString("dd.MM.yyyy");

OR

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.

In case you want to format the entire column then it would be better if you can set the property for your concerned column

gridview1.Columns[columnIndex].DataFormatString ="{0:dd.MM.yyyy}";

I think you will need to cast the column as BoundField to access the property.
