Web Forms :: Accessing Server Controls From A Class?
Mar 27, 2010
I have several .aspx pages that all have identical code behind pages.For ease of maintenance,I would like all the aspx pages to share a common code behind page.
To do this I have created a MyCommonClass class,which contains the common code.In the code behind of the .aspx pages, I have:
Partial class MyPage
Inherits MyCommonClass
End Class
But now the controls declared in the .aspx pages are not accessible in MyCommonClass.fix this?

I need to be able to access simple page controls like a textbox from my page class. So if I have a simple aspx page with a textbox on it, I'm trying to do something like this. i'm not using codebehind btw:
[Code]....
I thought maybe I could pass a reference to the page into the class, something like:
[Code]....
But that's not working either. How can I access page controls from my class?

I have a regular method I want to call. I need to use properties of the GridViewRowEventArgs Class within this method.
i.e.
[Code]....
Of course the above code is not valid because I don't think you can put GridViewRowEventArgs within the method like that. I don't want to put it within a event handler because that even handler is doing other things. I want to be able to call this seperatley.

I'm wondering how I can go about accessing page controls from a separate class I've made. I've tried a few things I found using google, but no luck :(
What I'm trying to do is keep a function that is used often, in a global class.
The function then accesses a page literal and calls ScriptManager.RegisterStartupScript. I was hoping this is possible, so then this function wouldn't have to be copied to all of the pages.

Last night you guys here on this forum helped me in accessing properties of a dynamically loaded UC in an aspx page. Now i am facing another hiccup.
My code behind is : public partial class SiteUserControls_Message_Messages : BaseControl
In one of the click events i am loading three web users controls:
protected void RadTabStrip1_TabClick(object sender, RadTabStripEventArgs e)
{
SiteUserControls_Message_Create CreateNewMessageUC = Page.LoadControl(CreateMsgControl) as
SiteUserControls_Message_Create; // typecasting the UC
[Code]....
Now i want to access this variable CreateNewMessageUC in another event like this:
protected void MarkAsUnreadLinkButton_OnClick(object sender, EventArgs e)
{
CreateNewMessage.CreateNewMessageUC.RefreshSendTo();
[Code]....
But when i access teh variable in another event it is always null.

I have an issue with trying to create a Pdf file from my webpage. Basically, everythig involving creating the Pdf (using iTextSharp) is done, and I'm doing this as a File Stream (i.e, I'm saving the Pdf on local machine). Now what I'm trying to do is create it as a Memory Stream (i.e, open the Pdf from the browser). I was able to do this earlier when I wa still at the 1st version of the application, and all of the code behind was incluced in my .aspx.cs file. But now, I've kept the code in the .aspx.cs at a minimum and put the cude in classes and I'm creating onjects of thoses classes from the .aspx.cs
The problem is that the code from creating the Memory Stream is in a class as follows:
[Code]....
As you can imagine, the compiler cannot recognise "Response" as it's in a seperate class instead of in .aspx.cs

I'm accessing a Masterpage property from a regular page by doing the following:
[Code]....
I get the following error message:
Compiler Error Message: CS0246: The type or namespace name 'SecondMasterPage' could not be found (are you missing a using directive or an assembly reference?)
My base class file is a file called BaseClass.cs in my App_Code directory. Other functions in there work without errors. Why?

So i have some existing functionality from an older ASP.Net app that is a static class.
Say there's a static method in that class that returns a dataset that I would like to bind to something like a gridview or whatever I can build using MVC3.

I am using VB.Net/ASP.Net 2008/3.5 to create a Web Application and I am trying to access the Profile Class.
I notice that unlike a "Website" that you cannot access the Profile class from a "Web Application" and I was wondering what is the best way of adding the Profile class to a Web application?

I set up various global parameters in Global.asax, as such:
Application["PagePolicies"] = "~/Lab/Policies.aspx";
Application["PageShare"] = "/Share.aspx";
Application["FileSearchQueries"] = Server.MapPath("~/Resources/SearchQueries.xml");
I have no problem accessing these variables form .ascx.cs or .aspx.cs file -- ie. files that are part of the Web content. However, I can't seem to access 'Application' from basic class objects (ie. standalone .cs files). I read somewhere to use a slight variations in .cs files, as follows, but it always comes throws an exception when in use:
String file = (String)System.Web.HttpContext.Current.Application["FileSearchQueries"];

I have one C# windows class library type project which has a web reference whose settings are automatically added in to settings.settings file( Webservice name, type, scope, value).
I also have one separate ASP.net project which has let us as suppose, one page with a button. When I click this button, it calls a method of referred DLL of previous project and control goes there.
When in that project, when control goes in to location where I use this web reference, it tries to get the URL of web reference from settings file and raises an exception - 'The current configuration system does not support user-scoped settings'.
So, What is the way for me to call a c# project having web service in a asp.net project ? This is really a source stopper for our development.

I have a Custom WebControl. Inside this control I add a button and I want it to access an EventHandler that is on the WebForm where the control is included. The handler handles with controls from the WebForm, so it has to be there. I could probably manage to take the button out of the control, but it would be better to keep it on the control, for organization sake.
public class LanguageSelection : WebControl
{
private List<Language> _Languages;
private CSSImageButton btnOk = new CSSImageButton();

I need to make a webservice in .net (I know how this works) but then I need to get data out of a database. But my company wants to make it in a way that you can use the system with multiple databases.
So my option was make multiple abstract classes which contains the folowing code (depending on the database type, this would be a SQL database)
public abstract class AbstractDAO<T, Tid>

In my C# asp.net 3.5 web application I am having controls like div tag inside that one textbox and one check box and the page is having a submit button. So in this submit button click I want to make the controls inside the div tag visible.. I am calling a JQuery function to do this. All the statements are getting executed but the control is not visible.. Following is the code in my JQuery function
$("input[name$='QuestionAndAnswerEditorDiv']").show();
$("input[name$='answerLabel1']").show()
$("input[name$='wmd-AnswerTextBox']").show()
My div tag and its controls in the user control page are like the following
<div id="QuestionAndAnswerEditorDiv" runat="server">
<div id="wmd-button-bar" class="wmd-panel wmd-button-row"></div>
<textarea name="QuestionandAnswerTextArea" runat="server" id="AnswerTextBox" onkeyup="prettyPrint();" class="wmd-input editor" cols="92" rows="15"/><div class="wmd-preview text-preview preview" style="-ms-word-wrap: break-word;"></div>
As I noticed these controls are make visible=false in another page so they are not coming in the page source.. So Let me know how to work these controls now

I created a httpHandler that successfully implements IHttpHandler for handling file uploads. It works perfectly fine. You send the file with the form, the class receives it and will save it to hard disk. It reads chunks of file with ReadEntityBody function of HttpWorkerRequest class.
Here is the situation i'm faced with.If at any stage before trying to read the file with ReadEntityBody, I try to access Request object (even Request.InputStream.Length!) ReadEntityBody would return 0 means it won't read from file stream.
After further testing I found out the reason behind it. Accessing to Context.Current.Request object will trigger some sort of functionality that will cause asp.net to handle file uploads at that moment by it's own! I believe this is a bug.
for example exactly after this line of code, asp.net will upload the file completely, and so there will be no stream for ReadEntityBody to read from later.
int FileSize = context.Request.InputStream.Length;

Following code is an example, I just want to know if this can be done. I have an test.aspx file with this server side include tag;
<!--#include file="listOfCountries.htm" -->
Within listOfCountries.htm, I have:
<html>
<div>
<select id="countryList" runat="server">
<option></option>
...
</select>
</div>
</html>
Now, Is there a way to access "countryList" in test.aspx.cs file? On another note, say I didn't have the #include "Countries.htm" in test.aspx, is it possible to access the controls within Countries.htm from test.aspx.cs ? (i.e. accessing an external html file controls in cs)
