Schema.ini DateTime DGV Date or String ?

I am importing a .txt file to a gatagridview and writing out a Schema.ini file

My columns that contains a date value is empty in my DGV when i use the:
DateTime in my .ini file

If I set it to Char then my date is populated

Does this mean my dates in the text file are not really dates but strings ??

text files are strings, so your dates in your file are string representations of a datetime

Thanks Paul that would make sense

I added the DateTimeFormat= yyyy-mm-dd line in my schema file and it works

I thought I could set the format it came in and was doing dd-mm-yyyy
