Within a WebMethod I need to access a Page Property. The code is generating an error:
Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class
Is it possible to access page properties from WebMethods?
Here's my code:

Looking for sample to access the hidden variable which is declared in the aspx page in the webmethod.
View 1 RepliesI have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.
The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.
The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).

I've a problem: I've a GridView, with a folder structure, and an asp.net checkbox for each row in the gridview.Now, when the user clicks the delete button, it should delete all the folder entities where the user checked the checkbox.The problem is, there may not be a postback...So I used to use findcontrol in an ordinary asp.net button codebehind, but in a webmethod, it's impossible to access the page object, because WebMethods need to be static...Now I tried ctype(httprequest.current.request.handler,page) but that doesn't seem to work...
How can I get the page object to use findcontrol ?
I have user control in the master page. user control code behind page having public property called SetValue.
Now I want to set the value from content page .
I have the following web method , no success on return a correct Json format.
[Code]....
GetAll() return list of type "Company" POCO classes.
The web method complaint type "Company" could not cast to object. However I could not just return the Company type because client side Json only accept its 2 properties -"CompanyName", "ID" and I want to keep it that way.
Of cause, I had tried create a CompanyDTO which only have those two properties, but same error - "Unable to cast object of type..."
How should I modify in my web method to make it able to return a list of partial "Company" type in Json format?
to whom it may concern,
I wish to access a public property in a master page from a nested content page
is there anyway to do that without using "master type"
i found this link
http://www.velocityreviews.com/forums/t110057-accessing-properties-from-nested-master-pages.html
but i dont understand what "companywide" is
((CompanyWide)this.Master.Page.Master).HtmlTitle = "now it is working";
i dont want to use "MasterType" i would rather cast..

In a webforms app, I used to be able to access the master page to hide a link as follows through a property...
protected void Page_Load(object sender, EventArgs e)
{
HeaderFooter m = Master as HeaderFooter;
m.ShowHomePageLink = true;
}
However, when I try this in my MVC View, I can access the property but it doesn't hide the link as expected. It's as if the View is already rendered.
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<%
MyApp.MasterPages.HeaderFooter m = Master as MyApp.MasterPages.HeaderFooter;
m.ShowHomePageLink = true;
%>
...
</asp:Content>
FROM BOOK: To reference public properties in a master page, we add the @MasterType declaration to the content page and reference the property using Master.<PropertyName>.
QUESTION: But what happens internally? Does all of the master's and content page's properties, function gets complied into one class? Or something else?
I wanted to have the Editor control without the toolbars and found this guide: [URL]
The guide shows you how to make your own class derived from the Editor class, and gives some overload functions to remove the toolbars, and only have the bold and italics button.
I made my own "customEditorSample.aspx", and was able to reproduce what was in the guide.
However, in customEditorSample.cs, when I try to access the Content property of the control, it won't show up in the intellisense.
When using the regular Editor ajax control, I can save the contents to a label by doing:
Label1.Text = Editor1.Content; and "Content" would appear in the intellisense after typing the period after Editor1.
i have user control which consists of tree drop down and modal pop up and text box just to view my hirerichal data in tree - drop down list
the problem is when i try to get value from drop down list in debugging mode PROPERTY EVALUATION FAILED Just Appers Execution Stopped.
every thing in request also PROPERTY EVALUATION FAILED

I found this Article from link : [URL] .... that explains how to call server-side Method from javascript,
I used your code, my server-side function is static, public, and also I added
[System.Web.Services.WebMethod]Â
and
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
I want to pass a property of the type System.Uri to an WebControl from inside an aspx page.
Is it possible to pass the property like that:
<MyUserControl id="myusercontrol" runat="server">
<MyUrlProperty>
<System.Uri>http://myurl.com/</System.Uri>
</MyUrlProperty>
</MyUserControl>
instead of:
<MyUserControl id="myusercontrol" runat="server" MyUrlProperty="http://myurl.com/" />
which can't be casted from System.String to System.Uri EDIT The control is a sealed class and I don't want to modify it or write an own control. The goal is to set the url-property which is of the type System.Uri and not System.String.
I have a hidden field on my default.aspx page. Within default.aspx page I have a user control which has a label on it. I need the label to display the value on the hidden field. How can I go about this?
