Answer 1

Do you mean like this?:

dtData.Select("ID=1 AND ID2=3");

Answer 2

Okay, here is how I do such things...

    GridFieldDAO dao = new GridFieldDAO();
    //Load My DataTable
    DataTable dt = dao.getDT();
    //Get My rows based off selection criteria
    DataRow[] drs = dt.Select("(detailID = 1) AND (detailTypeID = 2)");
    //make a new "results" datatable via clone to keep structure
    DataTable dt2 = dt.Clone();
    //Import the Rows
    foreach (DataRow d in drs)
    {
        dt2.ImportRow(d);
    }
    //Bind to my new DataTable and it will only show rows based off selection 
    //criteria
    myGrid.DataSource = dt2;
    myGrid.DataBind();

Notice in my Select() I put the criteria in Parens between AND and OR

Hope this helps! Mike V
