User.Identity.Name  as an update parameter

Dear Experts,

I am hoping to add the windows username (User.Identity.Name) to the update string for a gridview - as a way of keeping track of which user has last edited the data. Additionally I would like to add a timestamp. The fields exist in my database, I am just not clear on how or where in Visual Web Developer I say something like "User.Identity.Name = @username"

(ie can I refer to code variables within my ASP page ... ? I have no idea).


I am sure there is an efficient way to do this and would appreciate your thoughts.

My code behind pages are in VB


Thank you in Advance
From a newbie.

Depends on how are you binding to the grid. Are you binding through code?

Hi Robasta,
No (at least I don't think I am...)
I have just created the datagrid via the design window and gone through the motions to make it editable (ticking box generate Insert/Update/Delete statements).

Everything (SQL, Gridview structure, Parameters) appears to be in the ASP page.  

Thank you.

Do this:

Code Behind:
protected void SqlDataSource1_Updating(object sender, SqlDataSourceCommandEventArgs e)
        {
            e.Command.CommandText = e.Command.CommandText.Replace("@Username","'"+ User.Identity.Name+"'");
        }

Open in new window



Page:
  <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
        ConnectionString="<%$ ConnectionStrings:elementalConnectionString %>"        
        UpdateCommand="UPDATE [Event] SET [UserName] = @Username, [Location] = @Location, [Date] = @Date, [IsDeleted] = @IsDeleted, [SlugUrl] = @SlugUrl WHERE [ID] = @ID" 
        onupdating="SqlDataSource1_Updating">

Open in new window

Hi Robasta
Sorry for the delays it was getting pretty late when I was trying this last night (in Sydney) - it didn't work straight off but I suspect that is my understanding not a problem with what you've provided.
I converted the code to VB via an online tool but it did not seem to be firing. I will try to implement over the weekend.
Cheers Split_Pin

Hi again,
This is the code that seems to be working for me now - slightly different, and I have removed the onupdating= from the ASP page altogether.

Thank you for getting me on the right track. I will leave the thread open for a bit in case you want to add anything or take exception to the code appearing below.

Protected Sub SqlDataSource_ControlName_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles SqlDataSource1.Updating

        Dim Username As String
        Username = User.Identity.Name

        e.Command.Parameters("@Username").Value = Username

    End Sub
