Whats wrong with my LINQ query Trying to Find a Record in List

I have this Grid in my c# application

The Display Value in column 1 has an ID and Description ( see screen below)

Selected Record From Combo Box withing Grid

When i change values in column1 I want the description written into column2

I am trying to use LINQ and a LAMDA Expression . My script is as shown below

[private void dgvDetailsTable_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
if (e.ColumnIndex == 1)
{

switch (this.dgvDetailsTable.Columns[e.ColumnIndex].Name)
{
case "dgvcmbarsaleditemid":
var result = ((List<InventoryItemModel>)dgvcmbarsaleditemid.DataSource).Find(x => x.INVITEMId.Equals(dgvcmbarsaleditemid.Selected));
this.dgvDetailsTable.CurrentRow.Cells[2].Value = result.INVITEMDescription;

break;

}
}
}[/code]

My database field name is INVITEMId and my DataGrid column 1 name is dgvcmbarsaleditemid.

In the debugger I can see that the 1188 records were selected and in the debugger i can see the loop search going on

See Debugger Screen below

Debugger Screen showing that I have ALL the 1188 records in my List

At the end of the looping it can not find the selected record and put it in the result variable even though the selected record
is on screen and coming from the database. See Error screen below
