Populate ComboBox From SQL Query

I am trying to populate a ComboBox from the result of a stored procedure. The stored procedure simply returns the distinct values of a single column from a table. I believe I am making a connection to the database and returning dataset. My problem occurs while trying to use the dataset as the source for the combobox. The error I get is "Cannot serialize the DataTable. DataTable name is not set'. Where and how do I do this?

Could someone help me with this?

Thanks,

Robert

  SQLQuery returns a Results which type is DataTable. 

  Results

  The results of the query as a DataTable.

   

  if you assign the Results as a variable named as 'dt'.

  Use Assign activity: dt.TableName = 'Any name'

  That worked.

  What I did was to add an Assign tool between the SqlQuery and DataTableToDataItemList tools.

  I set the datatable name like this dtResults.TableName = "foo"

  Then set the dtResults to variable iDataItems in the DataTableToDataItemList.

  Finally bind the ComboBox to iDataItems.

   

  Thanks,

  Robert

  Robert, I realize this was a very long time ago, but I am having trouble with that last step, to bind the combo box to the DataItemList.  I have a runtime process which creates a combobox on the fly and populates the list from the results of a SQL query.  I have created the DataItemList from the SQL query results, but I can't figure out how to set the combobox to use the dataitemlist.
