I would like to share a brilliant piece of code as a continuation to my Nuts N Bolts which I encounter on my day to day developments and maintenance here and there:

This is for removing repeated data from DataTale:

 public DataTable FilterDuplicateRows(DataTable dTable, string colName) 
            Hashtable hTable = new Hashtable();
            ArrayList duplicateList = new ArrayList();
            foreach (DataRow drow in dTable.Rows)
                if (hTable.Contains(drow[colName]))
                    hTable.Add(drow[colName], string.Empty);
            foreach (DataRow dRow in duplicateList)
            return dTable;
Using the function:
private void BindGrid()
                DataSet ds = (DataSet)ViewState["ds"];
                DataTable dt = (DataTable)ViewState["dt"];
                DataTable dtFiltered = new DataTable();               
                dtFiltered = FilterDuplicateRows(dt, "software");     
                gvRolePackage.DataSource = dtFiltered;
