Question

I have a gridview and a SqlDataSource.

In the SqlDataSource‘s update statement I’m trying to convert the string of the column to datetime with this:

Date = Convert(DateTime, @Date, 104) 
//this converts the string to mm.dd.yyyy .

I can’t find the code for mm.dd.yyyy hh:mm .

Your questions states you are using a GridView and a DataSource.

I’m assuming your source data is in a DateTime format in SQL Server.
If so, leave it in that format, otherwise, cast it as a DateTime when returning it.

Do NOT try converting it into a string on the SQL Server end or run a pass over your DataTable and convert it to a string using C#. That is the wrong approach to this.

All you need to do is set the DataFormatString on your GridView’s BoundField column like so:

BoundField bf = new BoundField();
bf.DataField = "xxxxx";//The field from your DataSource you are binding to.
bf.HeaderText = "yyyyy";//The column header text of your GridView.
bf.DataFormatString = "{0:MM.dd.yyyy hh:mm}";
gv.Columns.Add(bf);//Add the column to your GridView.
