I want to show in a TextBox only hour and minutes

//test ="08:00:00"
var tb = (TextBox) gridViewRow.Cells[2].FindControl("fstart");
tb.Text = test;


how to show only hours and minutes
"hh.mm"

Answer

You need to convert your data to TimeSpan and then use format:"hh\:mm"

string test ="08:00:00";
TimeSpan ts = TimeSpan.Parse(test);
Console.Write(ts.ToString(@"hh\:mm"));

In your case:

var test = dataRow.Field<TimeSpan>("fstart").ToString(@"hh\:mm"));

Remember to escape the colon :
