Solution 1

use datatable select method which has parameter filterexpression as string
this will get the filtered rows in datarow check if datarow is null

C#

DataRow[] dr = dt.Select("where id=" + id);

Solution 2

Alternatively use dataview

<pre lang="vb">
'assumming datatable is named dt
Dim dv As new DataView(dt)
dv.RowFilter = "id = " & ID
If dv.Count >0 Then
'Row exists
End if
</pre>
