I have a question about a C#.net solution file. I am trying to open a C#.net solution file with visual studio.net 2008 that my company obtained from a contractor. I can not open this file. I click on the file and it looks like it will open but it does not.
I am thinking problem could be one of the following:
1. This could be a 2010 C#.net solution file. If that is the case, is there some way to convert the visual studio ide to 2008? If not, I will just need a copy of visual studio.net 2010,correct?
2. My 2008 visual studio is setup for C#.desktop application. This solution file is asp.net. Thus would I need to install the asp.net options in my visual studio.net ide to be able to see
these files? If so, how do I add the C#.asp.net to to visual studio ide?

Dear All,

I have a strange problem. I have ascx control and I have only ListView in it. When I use generic method to fill this ListView with data I get Exceptiion - ListView is null. But when I use method without generics(with known parameter) everything is working fine(ListView is not null). Could you explain me why something like this is happening?
this works fine:
public void SetListViewDataSource(List<BaseBO> data)
{
this.ListView.DataSource = data;
this.ListView.DataBind();
}
and this is not working:
public void SetListViewDataSource<T>(List<T> data) where T : BaseBO, new()
{
this.ListView.DataSource = data;
this.ListView.DataBind();
}
I am using Model-View-Presenter pattern

I'm using ASP.NET 4.0 working in VS2010 right now only debugging not moved to a real server. I have some code to set the working directory node by node. This handles paths longer than the limit.
string[] dirs = targetDirectory.Split(Path.DirectorySeparatorChar);
foreach (string dir in dirs)
{
string adir = "." + Path.DirectorySeparatorChar + dir;
if (!Directory.Exists(adir))
{
Directory.CreateDirectory(adir);
}
Environment.CurrentDirectory = adir;
}
I'm seeing that when handling multiple requests the one request will write the cwd and the other request wil try to write too and they end up conflicting. I'm not really surprised.
This does totally foil my plans for world domination. Can anyone suggest something? Locking an object until I begin file operations? Is there a setting in IIS to make separate processes? I really could use some help with this one.

Maybe because of you used iframe,that's why your pop up alert at behind of the browser. At code behind after finish insert the data, create session and in successfully page,try to check session in page load and popup alert if session exist.Example:
insertpage.aspx.vb
Session("success")="anything"
successfulinsert.aspx.vb
If Session("success") <> "" Then
Response.Write("<script language=""javascript"">alert(""Successfully Insert the data"")</script>")
Session.Remove("success")
End If
Maybe my code got error because I simply write it without debug or test it 1st but that's the idea.

Dear all,
I use the code below for firing a method, however .. it's not firing. I use the same piece of code (different class though) a little further in my application and it's working fine.
protected void Page_Load(object sender, EventArgs e)
{
Control ce = LoadControl("TimeEntry.ascx");
pnlProjects.Controls.Add(ce);
foreach(Control ctl in pnlProjects.Controls)
if (ctl.GetType() == typeof(TimeEntry))
{
TimeEntry te = (TimeEntry)ctl;
te.LoadControls();
}
}
I don't want to put
LoadControls();
in my Page_Load of TimeEntry.ascx because it's posting back when I navigate away from the page and thus firing the method again.
Can any tell me what I am doing wrong.
Kind regards,
|

You can put the LoadControls in Page_Load but with below condition :
If(!IsPostback)
LoadControls()
This will cause the LoadControls to call only at the first loading of the page and not everytime postback occurs.
IsPostBack property is used to check whether the page is getting loaded first time of the postback caused by any control on the page.
Hope this helps.
All the best.
I quit being afraid when my first venture failed and the sky didn't fall down.

I am asking the question in this group. I orginally entered it into the wrong group C#.net.
I am wondering if you can tell me what would be the good items I can drag and drop from the visual studio asp.net 2010 tool kit that would acomplish the following tasks:
1. most of the data would be contained in a datagrid,
2. I would like to have a tab on the top of the webpage where the user can tab to over click the 'next' button to accomplish the following tasks:
*The first tab will:
a. allow the user to have a 'type' ahead feature so they can select what organization they want to work with,
b. there will be a datagrid where the user can check off what suborganizations that are affect,
c. There will be a datepicker so the user can select certain dates, and d. there would be a 'next' button and/or tab on top for the user to go to the next page,
e. On this page, there will be a 'save draft' button. This will not commit the data to the database, but it will save the work entered so far.
f. On this page there will be a restart button. Basically this clear out any data and allow the user to start from the beginning again
*The second tab will:
a. display the data entered on the previous page on the top.
b. there will be alot of rows where the data will be prepopulated, and/or allow the user to enter data.
c. This page will show any errors that the user made.
d. This page will also contain a description of what what kind of data is entered on that row,
e. This page will have a button or tab to update the database.
f. There will be a 'save draft' button. This will not commit the data to the database, but it will save the work entered so far.
g. On this page there will be a restart button. Basically this clear out any data and allow the user to start from the beginning again.
h. The final tab will show summary information of what was just entered.

Hello Everyone,
I am trying to use cookies in Custom Role Provider as sessions are showing null exception...
In my login.aspx I am using
Dim newCookie As HttpCookie = New HttpCookie("AccessRights")
newCookie.Values.Add("AccessRights", accessRights)
newCookie.Expires = #12/31/2012#
Response.Cookies.Add(newCookie)
In GetRolesForUser, I am trying to retrive the information from the cookie
If Not Request.Cookies("accessRights") Is Nothing Then
Dim foo as String = (Request.Cookies("accessRights").Value
End if
But it does not like the syntax. Get " Reference to a non-shared member requires an object reference error.
Please advice whether cookies will work in Custom Role Provider in ASP.NET 2.0

During the web development some time we need to add dynamic controls to a web page. Mostly developer’s face problems with dynamically added controls that they can’t get the event as the page post back.
I was also struggling with this issue and at the end I have found two possible solutions
1:- Add the control on page_Init
private void Page_Init(object sender, System.EventArgs e)
{
if (!IsPostBack)
AddControls();
}
private void Page_Load(object sender, System.EventArgs e)
{
}
private void AddControls()
{
TextBox dynamictextbox = new TextBox();
dynamictextbox.Text = "(Enter some text)";
dynamictextbox.ID = "dynamictextbox";
Button dynamicbutton = new Button();
dynamicbutton.Click += new System.EventHandler(dynamicbutton_Click);
dynamicbutton.Text = "Dynamic Button";
Panel1.Controls.Add(dynamictextbox);
Panel1.Controls.Add(new LiteralControl("<BR>"));
Panel1.Controls.Add(new LiteralControl("<BR>"));
Panel1.Controls.Add(dynamicbutton);
ViewState["controlsadded"] = true;
}
private void dynamicbutton_Click(Object sender, System.EventArgs e)
{
TextBox tb = new TextBox();
tb = (TextBox) (Panel1.FindControl("dynamictextbox"));
Label1.Text = tb.Text;
}
2:-Override method LoadViewState
private void Page_Load(object sender, System.EventArgs e)
{
if (!IsPostBack)
AddControls();
}
protected override void LoadViewState(object savedState)
{
base.LoadViewState(savedState);
if (ViewState["controsladded"] == null)
AddControls();
}
private void AddControls()
{
TextBox dynamictextbox = new TextBox();
dynamictextbox.Text = "(Enter some text)";
dynamictextbox.ID = "dynamictextbox";
Button dynamicbutton = new Button();
dynamicbutton.Click += new System.EventHandler(dynamicbutton_Click);
dynamicbutton.Text = "Dynamic Button";
Panel1.Controls.Add(dynamictextbox);
Panel1.Controls.Add(new LiteralControl("<BR>"));
Panel1.Controls.Add(new LiteralControl("<BR>"));
Panel1.Controls.Add(dynamicbutton);
ViewState["controlsadded"] = true;
}
private void dynamicbutton_Click(Object sender, System.EventArgs e)
{
TextBox tb = new TextBox();
tb = (TextBox) (Panel1.FindControl("dynamictextbox"));
Label1.Text = tb.Text;
}
Hope will work for you

Seeing that you claim this is a solution, if i were you i wouldn't post it as a question but rather write an article on the topic at hand. There's a facility to write articles on CodeProject, try that maybe?

Hi there,
Not sure if this is the right forum or not, but I thought I'd ask away.
Our product is thick client/server architecture. We have created a Web-based interface for our product using ASP.NET which does some basic lookups/field changes. We want to take it a step further and create a custom control within a webpage to show our floor-plan module.
Our thick client is written in C/C++, and I realize that in order to do what we want, we would need to port this code over to something a little more browser friendly.
Question:
What language/tools would give me the ability to:
a) Have a canvas where I can custom draw lines, shapes etc.
b) Get Click, Mouse Move events
.. All within a web-browser?
Any help/links you could provide would be great.
Cheers.
M.

Dear All,
I'm pretty good with C# however I can't figure out ASP.NET with C#. It's not the C# bit that gives me headaches but the ASP stuff. I have the following problem.
I've created an ASP website ( not entirely true, I used one of VS2010 templates ) and it's has login functionality. I'm using a Postgresql database in the backend and I can login fine. My Site.Master page got buttons in it, but I want a whole new series of buttons when the user has logged on correctly. I've created a new .aspx site that needs to load with a new Master Page. So I've created a new master page, called Site1.Master. It's pretty much the same as Site.Master but it allows me to use different buttons. But for some reason the login information is not display when this new page is loaded. Only after I hit 'F5' on my keyboard ( refresh ) it will show the info and the page works properly.
Site.Master :
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="Urenboeken.SiteMaster" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

CodeBehind="Time.aspx.cs" Inherits="Urenboeken.Account.Time" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
</asp:Content>
I load my new .aspx file form the login.aspx when the user is logged on correctly.
public partial class Login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
this.LoginUser.LoggedIn += LoginUser_LoggedIn;
}
void LoginUser_LoggedIn(object sender, EventArgs e)
{
Server.Transfer("Time.aspx", true);
}
}
Can someone tell me what I am doing wrong. Or am I going about it in a very wrong way to accomplish what I want. I hope someone can help out.
Kind regards,
