Sort column in DataGridView numerically in unbound mode

I have added a column to an unbound DataGridView in VS2005 and need to have the column sort "numerically". I have used this line of code:
DataGridViewItems.Columns(0).ValueType = System.Type.GetType("System.Int32")
which does indeed seem to change the property, but it still sorts the columns "alphabetically". How can I accomplish this?

Why "DataGridViewItems"? This code works perfectly:

Me.DataGridView1.Columns(0).ValueType = System.Type.GetType("System.Int32")
0
 
vadim63Commented:
And another thing. You have to set the ValueType before you put any data in.

that is the same as the code I am using, and I am setting it before I put any data in, and it is still not sorting correctly ( numerically), (i.e.) 9999 is appearing before 27895 when I sort descending.

This column is a "link" column if that makes any difference.

Sorry, no idea. The code, I posted shows me correct sorting. i.e.

Hi


This link might help u

Use int instead of String in the following expression .

 dt.DefaultView.Sort=(string)
                   this.ViewState["_orderBy"].ToString()+" ASC";

ok found the problem,
for some crazy reason I had just copied over this code and did not change it:

row.CreateCells(DataGridViewItems, .Item("OrderNum").ToString().Trim() ...


of course adding the ToString... messed it all up.

Thanks to both. Since vadim63 had more respnses I'll give him the majority of the points.
