Solution 1

1.You should change your SQL string similar with the next one:

C#

SELECT    c.cFirstName ,  c.cEmail  , c.cPhone , c.cMobile  FROM         CompanyMaster AS c RIGHT OUTER JOIN  Contact ON CompanyMaster.nCompanyId = Contact.nContactId LEFT OUTER JOIN  LeadSourceMaster ON Contact.nLeadSource = LeadSourceMaster.nLeadSourceID

2.In the ASP page change the sort expression like this:

SortExpression="c.cFirstName"

You can set alias in grid view for columns.

C#

//try this way to sort in datatable

         DataTable dtGetData = new DataTable();

         DataView dv = dtGetData.DefaultView;


         dv.Sort = "ColumnName" + " " + "ASC";

         //OR (You can pass it dynamically)

         dv.Sort = "ColumnName" + " " + "DESC";

         DataTable dtGetShipments = new DataTable();

         dtGetShipments = dv.ToTable();

         //bind this "dtGetShipments" datatable to gridview

You can try to change [FIRST NAME] to [FIRST_NAME]. Maybe that causes the problem.

After in GridView you can set up alias for your column as follow:

XML

<asp:GridView ID="yourGV" runat="server">
    <Columns>
       <asp:BoundField DataField="First Name" HeaderText="FIRST_NAME"/>
    </Columns>
</asp:GridView>
