Hi,
I'm hoping I've just overlooked something obvious here and someone will be able to help, one of those things where it's pretty simple and *should* work but doesn't...
I originally had this code on a page, which worked fine:
<div id="remote-support">
<h2>Remote Support</h2>
Pin code:
<asp:TextBox Width=80px ID="TextBox1" runat="server"></asp:TextBox>
<br /><br />
<asp:Button ID="Button1" runat="server" Text="Button" />
</div>
I replaced it with the following code on the page:
<div id="remote-support">
<% Response.Output.Write(Common.RemoteSupport(ThisPage))%>
</div>
And this is in some shared code in App_Code:
Public Shared Function RemoteSupport(ByVal ReferringPage As String) As String
RemoteSupport = "<h2>Remote Support</h2>" _
& "Pin code: <asp:TextBox Width=80px ID=""TextBox1"" runat=""server""></asp:TextBox><br />" _
& "<br />" _
& "<asp:Button ID=""Button1"" runat=""server"" Text=""Button"" />"
End Function
Now, what's happening is there's no controls appearing on the page, despite the page source containing the control tags as normal.
Suspect this has something to do with me getting something fundamental wrong, but can't quite get my head round what's going on. Surely it's possible to do this one way or another, maybe just not this way...
Any help would be greatly appreciated 
Thanks
Chris

RemoteSupport = "<h2>Remote Support</h2>" _
& "Pin code: <asp:TextBox Width=80px ID=""TextBox1"" runat=""server""></asp:TextBox><br />" _
& "<br />" _
& "<asp:Button ID=""Button1"" runat=""server"" Text=""Button"" />"
You can't do like that since asp:TextBox and asp:Button are Server-side control. The way how server-side controls work is that Web Server will generate the HTML controls and send them to the browser. So, you may write HTML control like that.. then it will work..
"<h2>Remote Support</h2>" _
& "Pin code: <input type=""text"" Width=80px ID=\"TextBox1\" /><br />" _
& "<br />" _
& "<input type=""button"" value=""value"" />"

Hello,
VS 2005
I have created an web service project and added a MSI setup project.
I added my own custom action which is a windows exe that will allow the user to select their own virtual directory for installing the web service. This worked ok.
I remove the default installation dialog from the user interface, and have the windows exe in its place.
However, as the project installs it always installs in the default C:\intput\wwwroot\websetup1 directory.
The way my custom action works is that it will create a new virtual directory then move all the files from the default directory "C:\intpub\wwwroot\websetup1". to what the user has specified. However, this mean that the default directory still exists. So the last thing that the custom action will do is delete this directory. However, as the custom action DLL has been installed in this directory I am unable to delete it "Access Denied"
So the possible solution that I have, is it possible to stop the setup installing in the default directory and install in the user specified directory instead of copying the directory across?
Many thanks for your suggestions,
Steve

1/ i want to display a youtube video or other content on a specific part of the page,and when its finished, display content from another source on the same place. im not sure how and in what control i should display the contect so i can get this ability. for example, if it was only text, i would do it with a label, changing its "text" property. i need the same ability but with other types of contents, primevally <object> and <embed /> content. do i need an update panel or the content source be changed with client side javascript only ?
2/ whats the process for creating "widgets" ? in widgets i mean all those objects like youtube videos, meebo and other that can be published on webpages only by adding an "<object>" tag to the page ? articles or tutorials ?
3/ whats the keyword "Or" is doing in vb.net ? what that line means ? "x Or y Or z" in vb.net ? how do i translated it to c# ?
4/ how do i plant a vb.net code in the middle of c# code in a .cs file ? is it possible ? i think i saw somthing about it..
thats it, i hope its not to much and all the questions are clear..

1. <asp:placeholder runat="server" id="phSomething">
content goes here
in the codebhind we set the visibility
CODEBEHIND:
if contained within a repeater or someother control: Page.FindControl("phSomething");
otherwise just:
protected void Page_Load(object sender, EventArgs e)
{
phSomething.Visible = true;
}
protected void On_Some_Event(object sender, EventArgs e)
{
phSomething.Visible = false;
}
Something to remember, the PlaceHolder control does not remember the contents of it between postbacks. So if it is needed to retain information across post backs, you can set all data to a session variable or cookie, or host the placeholder inside an AJAX Update panel and post back Asynchrously.
2. This isn't ASP.NET particularly... However you can set the "MinMaxClose" toolbar to not visible and that should help make it more difficult. I'm not a WinForms expert 
3. The process of widgets in ASP.NET (this is an ASP.NET forum) is more or less using XML web services to pass data or "consume" a webservice. I dont exactly know what all you mean here, the <object> tag dates back to HTML 3.0 or even earlier... It's more or less a Web Standard nowadays.
4. OR is a keyword that is used in conditional statements.
Let's say that we want to make an if statement:
If(Algoaddict_Posts_ASPNET_Forums OR Algoaddict_Posts_Anywhere_Forums)
Algoaddict_Answered = true
EndIf
In C#:
if(Algoaddict_Posts_ASPNET_Forums | Algoaddict_Posts_ASPNET_Forums)
{
Algoaddict_Answered = true;
}
In this case, OR returns a boolean true if either case returns true. Thus, you were answered. For more information, you can see MSDN Documentation on CONDITIONAL STATEMENTS and BOOLEAN OPERATORS.
--EDIT
Darn! You modified the questions!
4. Not really possible, no. However, you can create a vb class and call that class from inside a CS file.

thanx a lot !
1/ what happens if i want to set the content of the window in run time ? i cant use the approach of creating all the windows and only hiding and displaying them as you suggested. an i frame would do the work, is it still being used in asp.net 2.0 after ajax arrived with all its features ? or theres an ajax replacement ? cant this be achived with updatepanel ?
4/ about the Or - i know the original usage of it and how it can be converted to c# but in this specific case, visual studio says its an integer, and its not between boolean variant - this is the exact code:
"SetWindowLong(Me.Handle, GWL.ExStyle, m_InitialStyle Or WS_EX.Layered Or WS_EX.Transparent)"
when the last parameter should be of type "Window_Library.WindowLibrary.User32Wrappers.WS_EX()"
furthermore, i tried copying the exact code and replace "Or"s with "|" and get the following error message:
Error 1 Operator '|' cannot be applied to operands of type 'int' and 'Window_Library.WindowLibrary.User32Wrappers.WS_EX'
thanx again

I latebind my content all the time. That's an easy one.
protected void OnDataBind_Control_to_Show(object sender, EventArgs e)
{
SetCorrectView();
}
protected void SetCorrectView()
{
Series of if statements that check for control.txt or control.value = "" or null
}
If the control has data, show it. otherwise dont. Easy peasy.
In that case, I can see howit's being used, and the reason VS shows it as an integer, is that all three possible arguments sent to the function must be integers. So, in your case, the last argument can take any of those three specific arguments, but they must all be ints.

<%@ Register tagprefix="MyTagPrefix" tagname="MyHeader" src="Header.ascx"%>
Inside Header.ascx there is another control called QuickSearch.ascx, and there is a textbox that I need to get values from so tha I can display the results in QuickSearch.aspx.
How do I do this?
Please can some one help?

dim txt as Texbox = Ctype(TextBox, Header.FindControl("txtID"))
Or something like that in vb.net. C# is
TextBox txt = (TextBox)Header.FindControl("txtID");
I didn't get any requirements for the signature

Hey guys, I'm having a small problem with a scalar variable. I took the code from another project I wrote but there were a few changes in this new project so I wasn't able to do the same thing as last time. Anyway, now I'm getting the error "Must declare the scalar variable "@State".", mostly because I'm not exatly sure where to declare it.
The code is a bit scattered, but I'll try to make it as short as I can, without leaving anything out. Although I think the problem is in the SqlDataSource with the select prameters / control parameter
EDIT: In hindsight I really should have specified what I'm trying to do. There is a drop down list where users will pick a state of a variable from a database, then the infomation matching that state will be displayed accordingly.
Drop Down List:
<asp:DropDownList ID="DropDownList1"
runat="server"
DataSourceID="myFilteringDataSource"
DataValueField = "State"
AutoPostBack = "True">
</asp:DropDownList>
The SqlDataSource:
<asp:SqlDataSource ID="myFilteringDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT DISTINCT State FROM tblTicket" >
<SelectParameters>
<asp:ControlParameter Name="State" ControlID="myDropDownList" PropertyName="SelectedValue" />
</SelectParameters>
</asp:SqlDataSource>
The VB/SQL code which would interact with the "@State":
Dim cmd As New SqlCommand("SELECT * FROM tblTicket ... WHERE ... tblTicket.State = @State", New SqlConnection(strCon))
cmd.Connection.Open()
Dim myReader As SqlDataReader = cmd.ExecuteReader()
The actual error I was talking about ("Must declare the scalar variable "@State".") comes up at 'Dim myReader As SqlDataReader = cmd.ExecuteReader()', so I pretty much know that I just have the variable delared in the wrong place.
I'd really appreciate any help, and if any more code is needed I'll post it right away.
Thanks,
aqzman

Most of your markup is not visible. Use the "Ignore HTML" option when you are posting markup code.
You have to add a parameter to the command object. The parameter that you have added to the SqlDataSource isn't used, as you don't use the SqlDataSource.

Oh, thanks for letting me know about that. I really should have looked over my message once it was posted.
I'm not exatly sure what you mean by it isn't used, the SqlDataSource is called in DataSourceID of the dropdownlist. Or maybe I've misunderstood you.
Thanks for the help!

The SqlDataSource is used on the page, but it's not used in the code that you have problems with.

You can't. Once the type has been set for an input element, it can't be changed. You have to create a new element.

Yeah one option would be to have two textboxes on the page. Then change the Style.Display property to show one or the other which can be done easily with Javascript.

Hi all,
I'm trying to load a user control dynamically into a web form. As I understand it, in order for the Placeholder to have a viewstate, I need to load the control in it before the Page load. So I'm trying to do that in the OnPreLoad method.
I have a link button on the web form. When I click it, I would like to load the user control in the placeholder. The first thing I do is save the UniqueID of the link button in the session. Now in order to be able to check which control has triggered the postback, I match the saved value in the session with the value of this.Request.Form["__EVENTTARGET"]. If they are equal, I go ahead and load the control.
Now the issues I'm having:
First, when the page loads for the first time, I have a javascript error that says
'null' is null or not an object 
The page continues to work however and when I click the link button, the user control is loaded and is displayed.
Now I have a button in the user control, when I click it, the user control disappears again on postback. I'm guessing this is because the placeholder didn't hold the viewstate as I expected. Would that be due to that Javascript error? The code I'm using is this:
if (this.Request.Form["__EVENTTARGET"] == (string)Session["linkID"])
{
uc = (UserControl)Page.LoadControl("modules/AddFeatureType.ascx");
PH_AddFeature_AddType.Controls.Add(uc);
}
where uc is declared globally in the page class.
When I remove this code, no javascript error anymore.
So my questions are: 1-Has anyone encountered a similar javascript problem and if yes, what is causing it exactly? 2-Is OnPreLoad the correct method to place the user control load process to maintain viewstate during postbacks?
Any other insights or issues concerning dynamic user control loading are welcome and appreciated.
Thanks.

Ok I found the problem. In the beginning I was loading the user control statically in the web form and then when I wanted to try to load it dynamically, I commented the line where I call it.
<td>
<asp:PlaceHolder ID="PH_AddFeature_AddType" runat="server"></asp:PlaceHolder>
<!-- <aft1:AddFeatureType ID="AddFeatureType" runat="server" />-->
</td>
This resulted in the comment tags to appear in the html code, I have no idea why actually. Anyway, I removed the comment completely and now the page loads without javascript errors and when i click the button in the user control, the required field validator of my textbox works.
Now I have another issue related to the field validators, I'm not sure if I should created a new thread for it or not.
In that same page with the user control, I have 1 textbox in the webform and 1 textbox in the user control, both have required field validators attached to them. I also have two buttons, one in the web form and one in the user control.
My problem is that when i click the button inside the user control, the field validator of the textbox located in the web form activates. My question: is there a way to have some kind of scope for the button? I would like only the field validator of the user control to activate when i click the button inside the user control. Is there a way to accomplish such a thing?
Thanks.
