In the code behind, the Control returned by FindControl is null. Why? How can I access the buttonMoveUpFormField and buttonMoveDownFormField controls? From the code behind, is it possible to access controls which are declared in the ItemTemplate section of the TemplateColumn section of a DataGrid?
I've run into an instance where I'd like to change the Enctype of the form declared in my current view's master page. I'd like to make the change in order to support attachments via Request.Files.
I have a Master Page which controls the styling of my site. In the Code Behind, there are a few class instances instantiated as well as variables. These classes validate user access and then create user objects
I have a few Web Content Forms which carries out instructions based on the user objects. So far it seems that on each Web Content Form I have to create new instances of the classes found on the Master Page. This is doubling my work for every Web Content Form.
Is there anyway I can inhereit Classes and objects instantiated in the Master Page Code Behind?
How to access a control declared in a Master Page in a content page.I have a ModalPopUpExtender in Master Page and i want to access it from a content page, how can i do that.

I know I have to be missing something simple, but yes, it's stumped me. I've read a couple posts that are similar, but didn't correct my issue. This seems too easy, so here's my situation. I have a Login.aspx (using VB). Here's my (partial) code for this page:
[Code]....
Then in the Login.aspx.vb, I'm getting the error as stated in this posts subject line:
At a bit of a loss here. As the subject says, I have a repeater control that uses the variable xmlN which is declared in my Sub Page_Load. Posted code below.
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: BC30451: Name 'txtUser' is not declared.
I have a Master file and an .aspx page which makes use of the Master file. I am currently working through implementing a new feature (see [URL] if interested), but essentially the problem has arisen after added Javascript code to my Main.Master page. Whenever there is a <%= %> in the Javascript code pointing to an object in the .aspx page, an new compilation error occurs:
Compiler Error Message: BC30451: Name 'ModalPopupExtender1' is not declared.
For example, the following is contained in Main.Master:
var modal = $find('<%=ModalPopupExtender1.ClientID%>'); document.getElementById("<%=Image1.ClientID%>").src = imageList[imageIndex];
However, ModalPopupExtender1 and Image1 are contained in Search.aspx.
Could not find schema information for the element [URL].NetConfiguration/v2.0:configuration'. and to resolve this i did google again and found a [URL] which is saying to remove that "xmlns" to get error resolved.
Im tring to get a CMS up and running for work and come to the conclution that the FormView is the way to go.
I have an edit page and would like to have a dropdown list where people pick a "Parent", for my site map/Navigation, from the list instead of needing to know the ID of the Parent. I can do this for my "Add New Page", with no FormView, but when I place it within the formView for my Edit Page the DropDownList1 stops being declared.
So what I need is something like: Parent = Dropdownlist1.serlectedItem.Valu But have no Idea how to achieve this using my FromView, two ObjectDataSource's and the dropdown list.
I have tried to link a asp:Lable text to the value of the Dropdownlist so I can pass that back to the DB with no luck.
The Code behind is as good as blank so may need to add stuff in there but again cant if I cannot declare anything within the For View :(
I am trying to use a checkbox that is dynamically declared in an .vb file that I am trying to write into my .aspx page. I am able to write a normal checkbox of <input type='checkbox /> from the .vb Class using Response.write, but it comes up blank when using <asp:Checkbox runat='server' />I need to pass whether or not the box is checked back to the server, because I am having to either approve something if one is checked, reject something if the other is checked or do nothing if neither are checked. I have figured out how to make them mutually exclusive either way so that is not the problem.
I have an application which I have worked on several times, but this week I've been trying to get the application to work on a new laptop and failed. First there were was some dependency issues with some controls like the AJAX Control Toolkit and AJAX Extensions, but now that I have everything I'm still getting errors. The errors that I'm getting are only in the App_Code classes. For Example I have the following references in the web.config
I am using ASP.NET and VB to display a message(label) while the datalist is empty like this <asp:Label ID="lblEmpty" Text="No Data To Display" runat="server" Visible='<%#bool.Parse((dlErgebnis.Items.Count==0).ToString()) %>'></asp:Label>
I am getting a error "the name bool is not declared".

i have a fileupload control from which i need the path of a text file. After selecting the file,i need to open the file for reading the data from the text file.For this, i used the following code to open the text file.
fp=File.OpenText(FileUpload2.PostedFile.FileName)
This is working fine in my system.The FileUpload2.PostedFile.FileName statement gives the path of the file.The File.OpenText method opens the selected file.But when i run my project in IIS,it gives the following error:
"File.OpenText is not declared."
The FileUpload2.PostedFile.FileName statement is not retrieving the path, it retrieves only only the filename.what could be the reason?
