hi,
I'm trying to convert a VS2003 project to a VS2005.
I'm working under Vista, i'have IIS6 installed in local.
after excuting this line
aspnet_regiis -i -enable
I've try to open my project but I've got this error
Unable to open the Web 'http://localhost/MyProjectFO/Test.csproj'. To access local IIS Web sites, you must install all of the following Windows components: Internet Information Services IIS 6 Metabase and IIS 6 Configuration Compatibility ASP.NET In addition, you must run Visual Studio in the context of an administrator account. By default, Windows runs applications in a limited-privilege user account even when you are logged on to the computer as an administrator. To run Visual Studio with administrative privileges, right-click the Visual Studio icon and then click 'Run as administrator'. For more information, press F1.

thanks for Help!!

Create a virtual directory as MyProjectFO mapped to the project directory and try to migrate.

I want to add textboxes on the click of button to the placeholser, i did this by adding this code on the click event of button.

TextBox txtBox = new TextBox();
PlaceHolder1.Controls.AddAt(0, txtBox);
txtBox.ID = "1";

but when i click on another button (on postback), there is no control in placeholder, i did google and found that i need to save state of contorl in viewstate, so after initilization, i can access these controls, but dont know how to implement this, will you please guide me with code snipt which event needs to be override or something else
any help will be highly appriciated.

Many thanks & Best Regards,

I would guess you are only adding the controls if Page.IsPostBack = false, you need to add the dynamic controls on every postback, try this:

<br />
Partial Public Class _Default<br />
    Inherits System.Web.UI.Page<br />
<br />
    Protected Overrides Sub CreateChildControls()<br />
        MyBase.CreateChildControls()<br />
<br />
        Dim textBox As New TextBox<br />
        textBox.ID = "TextBox1"<br />
        PlaceHolder1.Controls.Add(textBox)<br />
<br />
        Dim button As New Button<br />
        button.ID = "Button1"<br />
        button.Text = "Click Me"<br />
        AddHandler button.Click, AddressOf Button1_Click<br />
        PlaceHolder1.Controls.Add(button)<br />
<br />
    End Sub<br />
<br />
    Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)<br />
<br />
        Dim label As New Label<br />
        label.ID = "Lable1"<br />
        label.Text = "I was just posted back"<br />
        PlaceHolder1.Controls.Add(label)<br />
<br />
    End Sub<br />
<br />
End Class<br />

Hope this helps

Thanks for reply.

It helps me, but not in my current scenrio.
*I want to add controls to placeholder when IsPostBack==True
I have this scenrio: one course can have many dates, and i am inteneded to save course info & dates info on single click event of button.
For that i want to put a placeholder control in the ajax update pannel, and a button to add text box to enter date in it, each time the button is clicked a one more text box should be addto that place holder, and previous text boxes should also retain there values selected by user.
And at the end when i click on save button, i want to get the values of textboxes in placeholder control.

Many Thanks & Best Regards,
Adnan

The following will do what you are after. It assumes you have a ASPX page with an UpdatePanel containing a PlaceHolder and a Button:

Partial Public Class _Default
    Inherits System.Web.UI.Page

    Private Property TextBoxCount() As Integer
        Get
            If ViewState("TextBoxCount") Is Nothing Then
                ViewState("TextBoxCount") = 1
            End If
            Return CInt(ViewState("TextBoxCount"))
        End Get
        Set(ByVal value As Integer)
            ViewState("TextBoxCount") = value
        End Set
    End Property

    Protected Overrides Sub CreateChildControls()
        MyBase.CreateChildControls()

        For textBoxCounter As Integer = 1 To TextBoxCount
            AddButton()
        Next

    End Sub

    Private Sub AddButton()

        Dim textBox As New TextBox
        textBox.ID = "TextBox" + PlaceHolder1.Controls.Count.ToString
        PlaceHolder1.Controls.Add(textBox)

    End Sub

    Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click

        AddButton()
        TextBoxCount += 1

    End Sub

End Class

I can send you the sample project if you want.

Cheers

Even if you use normal JavaScript to load static items in Dropdownlist, the IE will flicker. Because Dropdownlist/Combo box is Windowed Control and the rendering would be different in IE. This is a bug in IE, which is fixed in IE 7.

So, there is nothing to panic... There is nothing wrong with the UpdatePanel too...

Thank you for your respond but the account Iam using to access these applications is an Administrator account and Iam running the applications localy so when I want to set permissions for the registry key the Allow check boxes are not visible because it is supposed that the administrators have all permissions on the computer.

I am too late but i will never give up

1. Start Registry Editor (Regedt32.exe).
2. Select the following key in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC
3. On the Security menu, click Permissions.
4. Type the required permissions for the account that is accessing the Web page.
5. Quit Registry Editor.

Hope this will Solve your Problem.
