    I'm using telerik tools version v.2013.1.32120

    I want to populate a radGridView from an oracle or sas data table and then set AllowRowReorder = True and allow the user to rearrange the rows however they want locally and then I can handle the database update.  My issue now is that I pull my data down into a C# datatable on the client and then when I set it as the source for my radGridView it will not let me rearrange the data.  How can I change this to be unbound mode to allow the rearranging within the datatable but not on the server table?

    using (OracleConnection oraConn = new OracleConnection(sConn))
       OracleCommand sasCommand = oraConn.CreateCommand();
       sasCommand.CommandType = CommandType.Text;
       sasCommand.CommandText = sSQL;
       OracleDataAdapter da = new OracleDataAdapter(sasCommand);
       DataTable dt = new DataTable();
         radGridView1.DataSource = dt;

    Thank you,

    Hello Jerry,

    Thank you for contacting Telerik Support.

    You can not use DataSource and AllowRowReorder=true simultaneously to achieve your goal. If you have a DataTable filled with the necessary data, you should iterate it to populate manualy the RadGridView. Thus you can allow reordering rows. Please have a look at the following code snippet:
    private void Form1_Load(object sender, EventArgs e)
                // TODO: This line of code loads data into the 'nwindDataSet.Customers' table. You can move, or remove it, as needed.
                foreach (DataColumn col in nwindDataSet.Customers.Columns)
                foreach (DataRow row in nwindDataSet.Customers.Rows)
                this.radGridView1.AllowRowReorder = true;

    I hope this information helps. Should you have further questions, I would be glad to help.
