Re: Implement Icomparable

Thats what makes this so confusing. I can sort an int column, a
varchar(200) column, but varchar(10) gives me the Implement
Icomparable error message. Being new to .NET this stuff is really
confusing, and any help would be greatly appreciated. There also
doesn't appear to be any way to turn off sorting in the datagridView.

Hi Jim, I guess it's because for some types you have there isn't a
default comparer (like you have, for instance, for most numerical types
and strings ).

What do those columns contain (what's the datatype) ?

Creating a datagridView with a dataReader. Why do I get this message
when I click on the column header (some, but not all the column
headers) to sort??

sqlDR = sqlCMD.ExecuteReader
Dim intCol As Integer

With sqlDR
If .HasRows Then
DataGridViewProducts.Rows.Clear()
For intCol = 0 To .FieldCount - 1
DataGridViewProducts.Columns.Add(.GetName(intCol),
.GetName(intCol))
Next

DataGridViewProducts.AutoSizeColumnsMode =
DataGridViewAutoSizeColumnsMode.ColumnHeader
While .Read
Dim objCells(intCol) As Object
.GetValues(objCells)
DataGridViewProducts.Rows.Add(objCells)

End While
.Close()
End If
End With
