以编程方式设置GridControl列格式（DevExpress）

Question

I have a GridControl made by code:

GridControl gc= new GridControl();
gc.Name = "Grid1";
gc.AutoGenerateColumns = AutoGenerateColumnsMode.AddNew;
gc.ItemsSource = myDataTable;

The problem is that I have a column called "creation_time", and I want to change the default detetime format from dd/mm/yyyy to dd/mm/yyyy HH:MM:SS.

I'm trying to create a GridColum from the GridControl but I don't know if it's the right way

GridColumn colCurrency = gc.Columns["creation_time"];
colCurrency.DisplayFormat.FormatType = DevExpress.Utils.FormatType.Custom;
colCurrency.DisplayFormat.FormatString = "G";

Answer 1

I think the problem is that you use auto create column and in myDataTable has the variable type DateTime that creates a DateTime column (format without timespan). One solution is not to use AutoCreateColumn and create them manually, and then you can set the display options (formatString...) how you write

最后我做到了：

gc.Columns["creation_time"].EditSettings = new TextEditSettings() { DisplayFormat = "{G}" };
