ASP.NET recording user id in SQL Server

Hello,

I have a simple ASP.NET page that I want to capture the AD account a user is logged in with and record it in a SQL Server database.   I have the following SQLDataSource defined below.   I tried using SUSER_SNAME(), but realized that this only provided the account that I used to establish the database connection and not the AD account.   Is there an easy way to get the AD account and pass it into a Insert Parameter?   Does anyone have an example?

Thanks!

<asp:SqlDataSource ID="insTransaction" runat="server" ConnectionString="<%$ ConnectionStrings:MARTConnectionString %>"
     
InsertCommand="INSERT INTO TT_TRANS(ProjID, EmpID, TRANDATE, Hours, Description, Billed, CreatedBy) VALUES (@ProjID, @EmpID, @TDate, @Hours,@Desc,'N',SUSER_SNAME() )"
oninserted="insTransaction_Inserted">

<InsertParameters>
<asp:ControlParameter ControlID="DropDownList2" Name="ProjID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="DropDownList1" Name="EmpID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="TextBox1" Name="TDate" PropertyName="Text" />
<asp:ControlParameter ControlID="TextBox2" Name="Hours" PropertyName="Text" />
<asp:ControlParameter ControlID="TextBox3" Name="Desc" PropertyName="Text" />
</InsertParameters>
</asp:SqlDataSource>

actually this

System.Security.Principal.WindowsIdentity.GetCurrent.Name

will giv you your currently logged in user in the format DOMAIN\Username

YZlatCommented:
first you will need to disable anonymous access and then use  User.Identity.Name  to retrieve the windows logged in name

Sorry, but I am new to ASP.NET.   How would I put this into the insert parameter for the SQLDatasource?  Can you give me an example?

Thank you!

to get username without domain use

Dim usr, arrusr() As String
        usr = System.Security.Principal.WindowsIdentity.GetCurrent.Name
        arrusr = usr.Split("\")
        usr = arrusr(1)

try this:

InsertCommand="INSERT INTO TT_TRANS(ProjID, EmpID, TRANDATE, Hours, Description, Billed, CreatedBy) VALUES (@ProjID, @EmpID, @TDate, @Hours,@Desc,'N',System.Security.Principal.WindowsIdentity.GetCurrent.Name.Substring(System.Security.Principal.WindowsIdentity.GetCurrent.Name.IndexOf("\") + 1))" 
oninserted="insTransaction_Inserted">

or try something like this:

InsertCommand="INSERT INTO TT_TRANS(ProjID, EmpID, TRANDATE, Hours, Description, Billed, CreatedBy) VALUES (@ProjID, @EmpID, @TDate, @Hours,@Desc,'N',@ADUser )" 
oninserted="insTransaction_Inserted">

<InsertParameters>
<asp:ControlParameter ControlID="DropDownList2" Name="ProjID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="DropDownList1" Name="EmpID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="TextBox1" Name="TDate" PropertyName="Text" />
<asp:ControlParameter ControlID="TextBox2" Name="Hours" PropertyName="Text" />
<asp:ControlParameter ControlID="TextBox3" Name="Desc" PropertyName="Text" />
<asp:ControlParameter Name="ADUser" PropertyName="Text" DefaultValue='<% System.Security.Principal.WindowsIdentity.GetCurrent.Name.Substring(System.Security.Principal.WindowsIdentity.GetCurrent.Name.IndexOf("\") + 1))
oninserted="insTransaction_Inserted">
%>'> />
</InsertParameters>
</asp:SqlDataSource>

or you can do that from code using

insTransaction.InsertParameters("ADUser").DefaultValue = System.Security.Principal.WindowsIdentity.GetCurrent.Name.Substring(System.Security.Principal.WindowsIdentity.GetCurrent.Name.IndexOf("\") + 1))

Tried to use the example with the ADUser control parameter.   Is there a different type of parameter I should be using?   When I tried this, it said I needed to specify the controlid....  

Thanks!
