GridView Primary Key

[shapper]

Hello,

I have a data table which is already created with all columns and
data.

I need to define LevelName column as its Primary Key so I can use Find
in it.

I tried the following but it is giving me errors:

dtLevels.PrimaryKey = dtLevels.Columns.Item("LevelName")

What am I doing wrong?

Thanks,

Miguel

The PrimaryKey property of a DataTable is an *array* of columns, even if
there is only one column in the primary key:

dtLevels.PrimaryKey = New DataColumn(){
dtLevels.Columns.Item("LevelName") }
