Try this

C#

DataRow[] dtrw = dt.Select("ModuleID='" + RadNode.Value + "'");

The value needs to be passed in, not the variable.

I am not an expert, but, according to this page: "DataView RowFilter Syntax [C#]"[^] you have to drop the single quotes, try:

C#

DataRow[] dtrw = dt.Select(String.Format("ModuleID={0}", RadNode.Value);
