Web Forms :: Response Is Not Available In This Context During Page Unload?

Feb 7, 2011

When my asp.net aspx page unloads i am trying to check if the current session is expired. I have this code in the Page_unlaod and i get a "Response is not available in this context" error. What is the problem placing this code in the Page_unlaod?

[Code]....

the page is in a frame with 3 other pages so when the page is doing a postback, there is client side code that will the page 2 in the frameset to 100% visible, then when page is laoded and the document is ready it sets itself 100% visible in the frame. I have tried placing the code in page_load but when the session has timedout the pageload is never executed again. I have tried to place the code in the pageload of page 2 in the frameset but that causes some funny behavior and unwanted redirects.

.ashx Context.response.writefile - Use File On Remote Server?

Nov 27, 2010

I'm using an .ashx handler to retrieve an image file... It queries a local database, which retrieves the URL of an image which is hosted on Amazon S3.

But I can't use context.response.write(AmazonS3URL) because it returns the error '...is not a virtual path'.

Can context.response.write only return files that are on the local machine? Or is there another function to call remote files?

.net - The VS.NET Designer For My ASP.NET Pages Show "response Is Not Available In This Context" For All Controls?

Feb 7, 2011

I have a VS.NET solution that was originally a 3.5 VS.NET 2008 solution, now upgraded to VS.NET 2010 .NET Framework 4.0. I rarely use the 'Designer' tab to preview the generated controls of my ASP.NET pages, but in this instance I want to to see the wizard of an Object Data Source Control.Now ALL of my pages (content pages of a single simple Master page) show the message "response is not available in this context" for all of my controls. I tied deleting the page from my project, adding a new page, and copying back in the source and code; same error. I also tried cutting out controls 1 at a time, and clicking "Refresh" in the designer but I can't find out the problematic issue. Remember every single page in my solution does this.

Web Forms :: Webpage Hangs After On Unload Event?

Nov 24, 2010

I have a web application which hangs after clicking a checkbox which is set to autopostback. This checkbox is supposed to do some process.

When I did the breakpoint, the application does not go to the On_PageLoad event but goes directly to the On_Unload event. After that, it hangs. It does not go to the On check changed of the checkbox.

Here are the events that are only called after the checkbox has been ticked.

Web Forms :: Prevent Unload Controls Loaded Dynamically

Jan 13, 2010

I'm developing an ASP.NET Web application with WebForms and C#.
I have this aspx page:

<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div id="divBody">
<div id="divHeader">
<asp:Button ID="Edit" runat="server" Text="Editar" onclick="Edit_Click" />
</div>
<div id="leftColumn">
<asp:UpdatePanel ID="UpdatePanelLeft" runat="server">
<ContentTemplate>
<asp:Label ID="TryText" runat="server"></asp:Label>
<asp:TreeView ID="DestinationTree" runat="server" ImageSet="Simple">
<ParentNodeStyle Font-Bold="False" />
<HoverNodeStyle Font-Underline="True" ForeColor="#5555DD" />
<SelectedNodeStyle Font-Underline="True" ForeColor="#5555DD"
HorizontalPadding="0px" VerticalPadding="0px" />
<Nodes>
<asp:TreeNode Text="Raiz" Value="Raiz">
<asp:TreeNode Text="Destino_1" Value="Destino_1">
<asp:TreeNode Text="Punto_1_1" Value="Punto_1_1">
<asp:TreeNode Text="Contenido_1_1_1" Value="Contenido_1_1_1"></asp:TreeNode>
<asp:TreeNode Text="Contenido_1_1_2" Value="Contenido_1_1_2"></asp:TreeNode>
</asp:TreeNode>
<asp:TreeNode Text="Punto_1_2" Value="Punto_1_2">
<asp:TreeNode Text="Contenido_1_2_1" Value="Contenido_1_2_1"></asp:TreeNode>
</asp:TreeNode>
</asp:TreeNode>
<asp:TreeNode Text="Destino_2" Value="Destino_2">
<asp:TreeNode Text="Punto_2_1" Value="Punto_2_1"></asp:TreeNode>
<asp:TreeNode Text="Punto_2_2" Value="Punto_2_2">
<asp:TreeNode Text="Contenido_2_2_1" Value="Contenido_2_2_1"></asp:TreeNode>
</asp:TreeNode>
</asp:TreeNode>
</asp:TreeNode>
</Nodes>
<NodeStyle Font-Names="Tahoma" Font-Size="10pt" ForeColor="Black"
HorizontalPadding="0px" NodeSpacing="0px" VerticalPadding="0px" />
</asp:TreeView>
</ContentTemplate>
</asp:UpdatePanel>
</div>
<div id="rightColumn">
<asp:UpdatePanel ID="UpdatePanelRight" runat="server">
<ContentTemplate>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Edit" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
</div>
</div>
</form>
</body>

It is a header with two columns: On left column there is a TreeView, and on the left there is nothing (now there is a label to try the thing that I want to do).

When user select a node on treeview a click on Edit button. Code for click event is:

protected void Edit_Click(object sender, EventArgs e)
{
if ((DestinationTree.SelectedNode != null) &&
(DestinationTree.SelectedNode.Depth > 0))
{
BaseControl baseControl = new BaseControl();
UpdatePanelRight.ContentTemplateContainer.Controls.Clear();
switch (DestinationTree.SelectedNode.Depth)
{
case 1:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control1.ascx");
break;
case 2:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control2.ascx");
break;
case 3:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control3.ascx");
break;
}
UpdatePanelRight.ContentTemplateContainer.Controls.Add(baseControl);
}
}

Depending on node selected depth is going to load a custom control dynamically. It works, but when the user select another node on treeview, the original label is reloaded on right column.

Web Forms :: Capture The Current Handler / Context / Page In The MasterPage?

Oct 26, 2010

In my GlobalMasterPage I use a custom control which displays a logo and a Title:

<%@ Register Src="UserControls/Header.ascx" TagName="Header" TagPrefix="uct"%>
<body>
<div id="header">
<uct:Header id="Header1" runat="server"
TitleOfApplication = "Logging Viewer v1.0"
TitleOfTeam = "Team One" />
</div>
</body>
</html>

Now, on the pages that use that GlobalMaster page I have a button on each one which allows you to jump from one page to another,

basically I do a Response.Redirect.

What I am trying to do is to find a way to change the Title of the application according to the button that the user clicked. I was trying to get the current handler but that does not work well for me:

How To Unload C++ DLL In C#

Mar 21, 2011

I load a C++ DLL using DLLImport in my C# ASP.Net web application. The DLL basically reads some CSV files, and manipulates them and creates new files.

After I ran the method successfully, and run it again then I get C++ exception back.

I want to unload the C++ DLL from the website so a user can re- load the DLL and re run the method. Do you know how to either eliminate this error or get rid of this error message so the DLL can be unloaded after its run?

How To Unload / Quit An Unmanaged Dll While Running

Oct 6, 2010

In our WCF service we use a third party product (product C) for querying an external database. We can not change the code in this third party product.

The library is imported for exemple via Declare Function vbPriopti Lib "PRIMCSAM.dll" (ByVal a As String, ByVal b As Integer) As Integer Declare Function vbConnectionClose Lib "PRIMCSAM.dll" () As Integer etc

The problem we face is that the product C keep connections in memory and refuses more connections from the same user/ip address. And their "vbConnectionClose" subroutine does not do proper clean up, something is left in memory and we can therefore not do a new connection.

The only thing to do a new connection is to restart the wcf servcie appliaction on the web server. But I do not want to close my whole app and restart it because of errors in the product C, instead it would be better to just reload the imported dll again?!

What is the easiest way to handle this problem? Restart/close the imported dll? Work with appdomain?

I tried the FreeLibrary method but it did not work, [URL]

Depending on node selected depth is going to load a custom control dynamically. It works, but when the user select another node on treeview, the original label is reloaded on right column.
