Why have you added a CType call? In .NET 4.0, there is an overload of String.Join which takes an Object() array.

sw.WriteLine(String.Join(",", row.ItemArray))

because when I am not using CType I am getting this;

Option Strict On disallows implicit conversions from '1-dimensional array of Object' to '1-dimensional array of String'

So you're not using .NET 4.0?

Try this instead:

For Each row As DataRow In dtErrors.Rows
   For i As Integer = 0 To row.ItemArray.Length - 1
      If i <> 0 Then writer.Write(","c)
      writer.Write(row.ItemArray(i))
   Next
   writer.WriteLine()
Next

The "Option Strict On disallows implicit conversions from '1-dimensional array of Object' to '1-dimensional array of String'" error suggests that you're not.

Try a different overload[^]:

sw.WriteLine(String.Join(",", row.ItemArray.AsEnumerable()))

"These people looked deep within my soul and assigned me a number based on the order in which I joined."

Add Imports System.Linq at the top of your code file, and make sure you project references the System.Core assembly.

I am using RadAsyncUpload which is defined like this

<telerik:RadAsyncUpload ID="FileUpload1" runat="server" Skin="Forest" Width="272px">
</telerik:RadAsyncUpload>

<asp:Button ID="btnUpload" Width="180px"  Height="30px" runat="server" Text="Upload"
                           onclick="btnUpload_Click" />

Now it works and it uploads the file , but now i want to have a Progress Bar , so like other controls i did the following

<telerik:AjaxSetting AjaxControlID="btnUpload">
    <UpdatedControls>
          <telerik:AjaxUpdatedControl ControlID="btnUpload" LoadingPanelID="RadAjaxLoadingPanel1"></telerik:AjaxUpdatedControl>

    </UpdatedControls>
</telerik:AjaxSetting>

    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">
    </telerik:RadAjaxLoadingPanel>

if i add this Ajax code , my Upload does not work , it give me the Following Error

You can always access the controls of Child Page from Master Page.

So, just access that and put your data to those Child Controls.

If you want to do it from Code Behind, then this is very easy - Refer - How to access asp.net content page controls from master page [^].

If you want to do it in javaScript/jQuery, then just check what is the rendered html of those child controls in browser so that you can find their ids or else you can use ControlID.ClientID to select that control and then assign value to it.

Let me know it will help you or not.

Popup is hiding because the page is refreshing when you page the grid, you can use a Update Panel so that the grid do a Async PostBack without refreshing the entire page.

Hi all guru,

I got stuck with this problem for quite a long time. I searched through Internet and official web site of Ajax toolkit but getting no luck. Does anyone has luck getting it to work?

Error is: ModalPopupExtender.OnShowing that does not exist or cannot be set.

I'd appreciate any help.

Get Loggedin Domain\Username

Hello Experrts,
I need to get the logged in domain\username from my website.
The function I use is :

System.Security.Principal.WindowsIdentity.GetCurrent().Name;

But it returns :

NT AUTHORITY\IUSR

My web config settings are:

XML

<identity impersonate="true"/>
   <authentication mode="Windows" />
   <authorization>
     <allow users ="*" /><!-- This allows access to all users -->
   </authorization>

I googled for answers and it is suggested that if the content in webconfig file should be as shown above but it is not helping me. Frown | :(

Am I missing some setting here.
Please help me.

Thanks,
Raesa

Try HttpContext.Current.User.Identity.Name instead.

It returns an empty string. Frown | :(

That's because you've got anonymous access enabled. If you want to force everyone to authenticate, you'll need to replace <allow users ="*" /> with <deny users="?" />. You might also need to change the authentication settings in IIS.

Hello Richard,

I tried your above solution and modified authentication settings in IIS, I disabled Anonymous authentication and enabled windows authentication.
It allows only people with admin login to that server to login to the website and for the rest of the people within the same domain it gives error saying "Error 401: Not Acessible".

I am not sure, what is it that I am doing wrong here.

Please give me some advice.

Thanks,
Raesa

Try using Failed Request Tracing[^] to diagnose the error. There's also a post on the MSDN blogs[^] which might help.

Go to IIS Set Anonymous authentication disable and windows authentication enable this will solve your problem.

You technically should not be able to get that information, if you do, then it's coming from the server that request was made on, and not the client machine.

Below is the correct response to the query, because it came off the web server.

raesark wrote:
But it returns :
NT AUTHORITY\IUSR

If the query was made in a windows app running managed code on a client computer or server, then you would get the domain name and identity your looking for.

[edit]

You got the identity that made the request, which is anonymous or IIS_USR in IIS5 and IIS6

by design, Microsoft is closing the loopholes in asp.net when used for web applications, separating managed code functionality between windows apps and web apps. Someone should write and article on the subject.

Hello jkirkerx,

Thanks for the reply.
So, is there no way that I can get logged in username??
Please give me some advice.
I have done everything and it still returns me "

NT AUTHORITY\IUSR
