I have a question regarding NT Authentication. Currently I have my setup on NT authentication, however, I would like the application to gather credentials and not ask for login name everysingle time.
I have made the proper modifications in IIS. But i get that prompt everytime i get to that secure part of my application. ( User Password Domain)
Is this possible to have this authentication and not prompt for password at all?
My app is ASP.NET with C# code behind.

What browser are you using for testing? In fact, when you use the Windows authentication, your ASP.NET application relies on the authentication of the IIS, and if the browser can, it will automatically send the logon account to the IIS for the authentication. You need to check the documentation of the browser that you are using, for example with IE you can check the Security Settings (in the User Authentication section). FF by default does not send the user account to the server, and you can config the URI of your application as a trusted URI in the preferences file.

private void Page_Load(object sender, System.EventArgs e)
{
string nt_User,name;
nt_User = System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString();
name = nt_User.Remove(0,7);
this.lblUser.Text = name;
if(name == "david" || name== "tom")
Response.Redirect("Management.aspx");
if(!IsPostBack)
BindData();
}
This is the code I am using. Does it seem like my problem is in the code or possible in IIS?
Thanks

Hi,
I am developing an Web Application in ASP.Net with C#. In this application I have used the IsApiRewrite tool for Rewriting the URL. I have got a page named Images and this page has got a dropdownlist. When the dropdown list is autopostbacked then the original URL gets appended to the Rewritten URL. Not only that any WebControl on that page is not calling its handler function .Instead the original URL gets appended to the Rewritten URL. What i want is that when the dropdown list is autopostback then the Rewritten URL should appear in the browser. Kindly help me out in solving this problem.
Rewritten URL :http://localhost/Entertainment/Harr...s/Images/1.html
Actual Url: /Images.aspx?Category=Harry%20Potter%20Movies&id=1
After Selecting a new Item in Drop down list i get the URL as:
http://localhost/Entertainment/Harr...ter+Movies&id=1
The Rewriting Rule is: RewriteRule (.*)/(.*)/(.*)/Images/([\w-]+).html $1/Images.aspx?Category=$3&id=$4 [L]
Please Help me out.
Thanks.

Hi
I'm trying to do file listings on separate folders and display it on a datagrid. However, for some reasons the sorting is not working. Below is my code. Can anyone help? thank you
Sub createDataSource()
Dim DV As DataView

Dim DT As New DataTable
Dim DR As DataRow
DT.Columns.Add("Category", GetType(String))
DT.Columns.Add("Filename", GetType(String))
Dim DirInfo1 As DirectoryInfo
Dim FileInfos1() As FileInfo
Dim Fi1 As FileInfo
Dim DirInfo2 As DirectoryInfo
Dim FileInfos2() As FileInfo
Dim Fi2 As FileInfo
'-----------------------------
DirInfo1 = New DirectoryInfo("C:\TEMP\")
FileInfos1 = DirInfo1.GetFiles("*.*")
For Each Fi1 In FileInfos1
DR = DT.NewRow()
DR(0) = "Guide"
DR(1) = "" & Fi1.Name.ToString & ""
DT.Rows.Add(DR)

I have tried combinations of the following to cancel the postback of a ButtonField. I am obtaining the data to view via Ajax and do not want the postback. Any ideas?
Code Behind in the dgData.RowDataBound event:
If e.Row.RowType = DataControlRowType.DataRow Then
e.Row.Attributes.Add("onclick", "javascript:return viewRow(" & CType(e.Row.DataItem, BusinessObjects.Course).CourseID.ToString & ",this);")
End IfOr without the "return"
e.Row.Attributes.Add("onclick", "javascript:viewRow(" & CType(e.Row.DataItem, BusinessObjects.Course).CourseID.ToString & ",this);")HTML:
<asp:ButtonField Visible="true" ImageUrl="../images/ViewSearch.gif" ButtonType="Image" Text="View Record" >
<ItemStyle HorizontalAlign="Center" Width="20px" />
</asp:ButtonField> JavaScript
function viewRow(id, row) {
try {
if (!(previousRow==null)) previousRow.backcolor= row.backcolor;
previousRow = row;
row.style.background="lightblue";
document.getElementById("<%=tblEdit.ClientID %>").style.display="none";
document.getElementById("<%=tblView.ClientID %>").style.display="inline";
requestSimpleService = CourseList.GetCourse(id, populateCourse, onError);
return true;
} catch (e) { alert(e.message);
}
}Note I am using the "<%=tblView.ClientID %>" due to using masterpages.
Thanks,
Michael

Hi Michael,
You need to add the onlick attribute to the ImageButton (the ButtonField with the ButtonType="Image") instead of the the row (tr) element. So there are two ways here to cancel the postback of the ButtonField:
+ Get reference to the ImageButton which is automatically added to the cell:
if (e.Row.RowType == DataControlRowType.DataRow)
{
ImageButton btn = e.Row.Cells[cellIndex].Controls[0] as ImageButton;
if(btn != null)
btn.On_Client_Click = "clientsidefunction(); return false;";
}+ Use the TemplateField with the ImageButton in the ItemTemplate instead of the ButtonField:
<asp:TemplateField>
<ItemTemplate>
<asp:ImageButton On_Client_Click="clientsidefunction(); return false;" ... />
</ItemTemplate>
</asp:TemplateField>

Like this: (replace the X in cells(X) with the correct column number for you case)
Private Sub DataGrid1_ItemCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles DataGrid1.ItemCreated
If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
Dim c As Button = e.Item.Cells(X).Controls(0)
c.Attributes.Add("onclick", "return confirm('Do you really want to click this?')")
End If
End Sub
cheers

I m using a Pivot table and a chart in my asp.net 2.0(C#) application. I want to edit data in Pivot table and save in the sql database.
Is there any way of doing it?
|
|
|
|
|
What data do you want to save? Surely the data displayed in a pivot table is aggregated...
If you change the underlying data, I'm sure you can save it, but the answer to your question depends very much on how you are supplying the data to your pivot table - it's really just a matter of creating an update sql statement for anything that changes...

I saw one example of how to display Pivot Table
protected PivotTableClass pt;
pt = new PivotTableClass();
pt.ConnectionString ="Provider=SQLOLEDB.1;Data Source=AHD-2003;database=northwind;user id=sa;password=;";
pt.DataMember ="select * from suppliers";
pt.ShowDetails();
I m using OWC10. But there is no method named ShowDetails(). How can it be?
Do u have any example of how to display Pivot table programmatically.

If you have 2 images (a thumbnail and a large image) you can just put the thumbnails on the page and render the inline popups on mouseovers (i suggest doing this with javascript cause otherwise you'll have troubles with postbacks).
If you do not have 2 images you will have to render your own thumbnails (on pageload for example) with System.Drawing libary. Then you can save your thumbnails just like you should have 2 images.
For an inline popup you can put a div with style "display:none" wherin you put your image. And onmouseover (from your thumbnail) you change the style of the div to display:div. With css you can place the div where you want on the screen.

I have a asp.net 2.0 web application that needs to open a word template from server, user change something, and then save back to server. Is it possible? Any help is appreciated.

It is possible using Office Interop, but before you do I'd suggest you look at what Microsof themselves have to say on the subject:
1) licensing: Microsoft require Office licenses for any server wanting to do this:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q243006#kb2[^]
2) (more importantly) there are technical limitations to running this kind of thing on the web:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q257757#kb2[^]
If you scroll down to where it says "Problems using Automation of Office server-side" in para 2 it says (in bold!):
"This fact alone makes running Office Applications from a server-side environment risky and unsupported."
So all in all, not a good idea....
There are 3-rd party components you can buy which will do the job - do a Google search.
cheers

Thanks for the reply.
What I understand is that if using Office Interop Office needs to be installed on web server. Even so it still can not save changed word document back to server.
Do you have any suggestion for the 3rd party component.

I have this in my html
<asp:DataList runat="server" ID="dlEntry" >
<ItemTemplate>
<AddOn:PostItem runat="server" UserRegisterDate="8/9/1972" UserTitle="Testing" TotalPosts="15" UserLoginName="NickTurner"/>
</ItemTemplate>
</asp:DataList>
my class file looks like so:
private DateTime _dtUserRegisteredDate = DateTime.Now;
private string _sTitle = "";
private int _iTotalPosts = 0;
private string _sUserName = "";
protected void Page_Load(object sender, EventArgs e)
{
}
public DateTime UserRegistedDate
{
get { return _dtUserRegisteredDate; }
set { _dtUserRegisteredDate = value; }
}
public string UserTitle
{
get { return _sTitle; }
set { _sTitle = value; }
}
public int TotalPosts
{
get { return _iTotalPosts; }
set { _iTotalPosts = value; }
}
public string UserLoginName
{
get { return _sUserName; }
set { _sUserName = value; }
}
In the WUC control is looks like
<asp:Label ID="Label1" runat="server" CssClass="PostNormal" Text='<%=UserLoginName%>'></asp:Label>
The value is being set. I saw this from stepping through the code. But when it prints on the browser its blank. All of the properties.
This is VS2005
What am I forgetting?
Thanks
1 line of code equals many bugs. So don't write any!!

Hi Nick,
You cannot use the inline render code expression <%= ...%> to assign a value to the property of a server control. In this case, you either set the property in code or use the data binding expression:
<asp:Label ID="Label1" runat="server" CssClass="PostNormal" Text='<%# UserLoginName%>'/> And in the Page_Load you call the DataBind method of the label to bind the value UserLoginName to the Text property.
|
|
|
|

actually the problem was this
and yeah the equals was wrong
But if I have inline, I can not include text i.e...
Text='<%# UserLoginName%>' will work
but
Text='LoginName: <%# UserLoginName%>'
will not.
if I take out "LoginName:" and move that too another label it works. very odd
1 line of code equals many bugs. So don't write any!!

The sample code simply looks like this:
Text='<%# "LoginName: " + UserLoginName %>'
|
|

LOL.
I didn't think of that.
