I am trying to search a datatable using a compound key. I can create the compound key just fine, but when I go to create an object to pass to the find it give me an error. Below is a sample of my code. Any suggestions?

dim lblDT...etc...

Here is where I create the compound key, and it seems fine.

lblDT.PrimaryKey = New DataColumn() {lblDT.Columns("serialno"), _
lblDT.Columns("type")}

This is where I am trying to create an object to pass to the .find

dim objSearch As New Object() {10643, 28}

it if would work this is how the find would be.

Dim row As DataRow = lblDT.Rows.Find(objSearch)

What is the error you are receiving? When you say compound key is this only in memory or the .Net level? Are your actual tables (the database if being used) using a composite primary key? If this is a simple data structure being built in memory where do you populate the table, what type of data is this?

I was getting an invalid type, but I did figure out what I was doing wrong. The object DIM needs to be as follows:

Dim objFilter() As Object = {table1, table2}

Using this with the filter option seems to work out well, I know their are other ways (dataview etc..), I was just being a stubborn JA and wanted to get it done with Datatabel.

Thanks everyone for tying :-)
