View 3 RepliesWe deployed a UserControl to our testing server. Then made a change to the UserControl and re-deployed. I cannot get the change to take. We have cycled the ASP.NET server, deleted the file completely and re-copied, and also tried a suggestion to change the web.config in order to force all files to be re-compiled.
I definitely know that we are changing the correct file. At one point, I removed the UserControl file altogether and received the "File not found error" when trying to load the user control. The file IS the correct version on the testing server.

I have some user controls where I would like to add some javascript that uses Ajax and Jquery technology. Also these scripts should use Sys.WebForms.PageRequestManager.getInstance().add_endRequestand other functions of the Ajax framework.In the past I have added the related code to the hosting aspx page but it becomes a problem when re-using the same control in multiple aspx.
View 1 RepliesI tried using a codeblock syntax within a property sent to a web user control:
<uc1:MyControl ID="MyControl1" runat="server" SomeProperty="<%= somevalue %>"/>
The user control has the public property SomeProperty declared and also uses code block to display the property value:
<p><% = SomeProperty %></p>
The output on my page is unfortunately
<p><%= somevalue %></p>
And not the actual value. Anyone know of some workaround for this?
In one of my pages I use an usercontrol. The usercontrol has a textbox and a button on it. When someone adds text to the usercontrols textbox, I want to use the entered text in my page_init event. The problem is that in the page_init event, the textbox value is empty. How can I use the entered text in the page_init event?

Does anyone know a good way to embed user controls inside an assenbly so they can be reused across projects. I am not looking to create custom web controls. I have ascx files from different projects which I want to centrally use.
View 2 RepliesI am generating instances of a UserControl and putting them in an UL. In my UserControl there is a button with an event. I want to ask how I can keep the state of the UserControls I generated so that they remain on the page after a postback and also to catch their events.
For i As Integer = 0 To lstFoo.Count - 1
Dim liFoo As New HtmlGenericControl("li")
Dim ucMyFoo As ucFoo = LoadControl("userControls/ucFoo.ascx")
liFoo.Controls.Add(ucMyFoo)
ucMyFoo.DoSomething()
ulFoo.Controls.Add(liFoo)
Next
Let's say I have an a .ascx user control. How do I get its HTML markup into a string?
View 5 RepliesI have a complete web application code created by other developer using asp.net c#. I am trying to deploy it on IIS 7.5 on windows 7.
In this application, there is a root folder that contains very less code files & one web.config file. This code is online currently & when we open the url, it redirects to the sub folder which is
http://******.com/pages/home.aspx
On IIS when I try to open this same path locally as http://localhost/test_project/pages/home.aspx
it simply prints the code in browser as
<% Response.Redirect("Home.aspx"); %>
I have several dynamic user controls that I want to keep them in each postback. but the problem is when I click on menu item at first time, every thing disapeare in my page! even the things I created on design time. would somebody please help me to find out the problem of my code?it's realy urgent!!

We have two asp.net sites (based on episerver). Using Telerik Asp.net controls. We have some funtionality that we want to have availible in both sites. Right now one of the sites use webparts/usercontrols and the other uses usercontrols.
Is there any way to share the functionality between these sites? What I would like is to be able to share usercontrols between the sites.
We need to add 2 user controls to an aspx file, these 2 user controls have one telerik ajax manager each. but telerik only allows one ajax manager in a web page. I am getting exception while running the app.
Is there any way in aspx to seperate the user controls so that it will act as a seperate page?
I have an (almost) empty aspx page and I want to insert a certain number of the same user control in this page.
I tried to add them from the CodeBehind but it seems that the UserControls are completely empty.
In the main page (MainDiv is a div with runat="server"):
protected void Page_Init(object sender, EventArgs e)
{
WebUserControl1 uc = new WebUserControl1();
WebUserControl1 uc1 = new WebUserControl1();
MainDiv.Controls.Add(uc);
MainDiv.Controls.Add(uc1);
}
(it doesn't work if i put this code on Page_Init, Page_Load or Page_PreRender)
UserControl (gw is a Gridview contained in the UserControl):
protected void Page_PreRender(object sender, EventArgs e)
{
if (_data != null)
{
gw.DataSource = _data;
gw.DataBind();
}
}
when I arrive there, gw is null (this.Controls.Count is 0).
As the title says , i'm looking for some kind of technology that allows me to dynamicly add & remove usercontrols.Without a postback ofcourse :)A link would be awesome , example code would be super!
View 1 RepliesFirst off - has any recent .NET / Windows Service Pack / Windows Update changed the behaviour around the Visibility of Panels / User Controls? An area of our site has all of a sudden stopped working. The most recent change that I made was a few weeks ago, I've backed out the change from my development environment, but the issue is still happening.
I'll explain what is happening. I have a couple of forms where the same behaviour is happening, but they follow the same pattern:
On the form there is let's say 2 ASP:Panel controls. In each of these there is a separate ASP:UserControl. When the User first visits the page, they are shown the first Panel and User Control. On this control they complete a couple of steps and click Next. This fires an event on the main page, which hides the first panel and shows the second panel, at least that is what is supposed to happen - and if I debug and step into the code this is what is happening as normal. Except on screen, the first panel is no longer being hidden, so it would appear clicking the Next button does nothing.
I'm at a loss as to what has happening - nothing has changed, and stepping through the code it's working correctly, but the screen is not reflecting what is happening in the code.
My next step is to create an isolated set of test pages to recreate the issue. Will attach when done and investigated, hopefully this will solve it
Is it necessary to reload the viewstate of usercontrols during postback? I want to know in which case viewstate is set by default.

<%@ Application Codebehind="Global.cs"

I can't see anything about this in the forum, yet it's a problem I have both on my VPS demo box and on some live boxes too:
When I deploy anything requiring a re-compile (e.g. not just an aspx.cs, but a .cs file) about once in every three times, IIS crashes.
This then requires not just a restart of IIS, but a reboot of the entire server, to bring it back again. If I try to restart just IIS, it won't actually "stop", so it won't then start again.
I therefore try to only deploy updates late at night, but in urgent situations a problem which needs rectifying can be made much worse by an additional 5 minutes of hard downtime while the box reboots. I can't predict when this will happen, but now warn all my clients against any updates during "office hours".
Is this a known bug/fault - can I get around this, preferably not by using RDP and stopping IIS completely before I FTP the files across?
Both boxes are 32 bit Windows Web Server.
I'm creating a multi-tenant Asp.Net MVC 3 Web app, and using EF4.1 code first for the db model.For development I'm happy to use SqlServerCE in App_Data, and for production this will move to Sql Server 2008.
Say my context is called "MyModels", by default code-first looks for a connection string called "MyModels" in Web.config. This can be told to use a file in App_Data or changed to access a database in SQL2008. All fine so far.
But because of multi-tenancy, I'd like the SqlServerCE filename to match the unique id of the tenant (so App_Data would have "client_x.sdf", "client_y.sdf"; Sql Server 2008 would have separate databases). I can't work out how to direct to these different databases.
I've tried MyModels inheriting from DbContext and supplying a connection string (using a 'placeholder' conn string in Web.config and replacing "{clientId}" with the unique id), and I've also tried setting the connection string in the MyModels constructor:
base.Database.Connection.ConnectionString = xxx;
but this never seems to work. I always get the following error:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
( it's not yet 'configured' to use SqlServerCE, and so is trying to connect to Sql Server)
Tracing the code, Database.Connection.ConnectionString hasn't been read from Web.config at this point, so I can't search and replace that, and, possibly, it's getting overwritten by the 'placeholder' conn string later in the pipeline.I reckon this must be quite straightforward and I just can't find the 'hook'.
