Hi

Had a look at that i tried

Dim foundRows() As DataRow
' Use the Select method to find all rows matching the filter.
foundRows = dt.Select("ContactID = 3")

cContacts.DataSource = foundRows '
cContacts.DataBind()

But now says

DataBinder.Eval: 'System.Data.DataRow' does not contain a property with the name ContactID.

any idea?

This one

cContacts.DataSource = foundRows

I check the length of foundRows and it equals 1 so it has a value

Cheers

OK, post your DataGrid code from the HTML page as well

The reason it is erroring now is because you have the following (and also other references) in your DataGrid HTML:
Code: 
Text='<%# DataBinder.Eval(Container, "DataItem.ContactID") %>'
As you have used the Select command of the DataTable to produce an array of DataRows, the array doesn't have a column named ContactID unlike the original DataTable which did. Therefore the error is saying that "'System.Data.DataRow' does not contain a property with the name ContactID.

Does that make sense to you?

Hi

IT makes sense but why doesnt the datarow now have these colomn names?

Is there a way around this??

Cheers

A DataRow cannot contain column names because it doesn't have the ability to create columns, hence the name DataRow. Think of it like a row of Data in a database; you would have a table that contains columns and you would also have rows that belong to this table. It is exactly the same in this scenario with DataTables and DataRows.

If you wanted you could always add the DataRows to another DataTable by using DataTable1.Rows.Add
