C# - Making A Control Visible On A Seperate Page, But Not Visible On The Page Which Contains The Control?

Jul 7, 2010

I have a masterpage (which we will call 'default'). This contains a second page (web user control) -'second'. And finally a third 'print' page. The 'print' page is also a web user control, however, it merely has a placeholder that contains the 'second' page.Is there a way I can add a control to the 'second' page - such as a literal, and only have it visible on the 'print' page?

C# - How To Tell If The Control Or Control Interface Is Editable By The User

Dec 1, 2010

I'm looping through an array of controls and need to know which controls an end-user has the ability to (via JavaScript or directly) change the value that gets posted back. Where can I find such a list?

So far I have this:

Private Function IsEditableControl(ByVal control As Control) As Boolean
Return TypeOf control Is IEditableTextControl _
OrElse TypeOf control Is ICheckBoxControl _
OrElse GetType(ListControl).IsAssignableFrom(control.GetType()) _
OrElse GetType(HiddenField).IsAssignableFrom(control.GetType())
End Function

Asp.net - Control Is Found But It's Not Implementing The Interface?

Oct 20, 2010

We have a WebForms Control which requires that the ID of another Control implementing ITextControl is provided.What exception should we throw if there is no control with that ID or a control is found but it's not implementing the interface?

[code]...
Should we split it into two cases and throw one exception if there is no control with that ID, and another one if said control does not implement ITextControl?If so,which exceptions should we use then?

How To Control The Permission-related User Interface

Mar 25, 2011

I am new in developing using asp.net.

I use java(struts2) to do the web application before,it is easy to control this use the jsp tag or struts2 tags: For example(suppose the "do something" operation need use login):

<s:if test="#session.user!=null">
<span>do something</span>
</s:if>

So if a user did not login,he will never see the menu of "do something".

Now I wonder how to make it in the asp.net?

Is this controled in the xx.aspx.cs?

Custom Server Controls :: Implementing An Interface From A Class Library In A Custom Control?

Jul 8, 2010

I'm building an n-tier application, with the web client and the class library separate. I'm also using the factory pattern of development, using interfaces to act as containers for different objects they are associated with. The problem I'm expreriencing is that I declared a public interface class in the class library and I can create an instance of it in in my aspx pages but whenever I declare it in my custom control code-side, i get an error, like so:

Error 20 The type or namespace name 'IContentMaker' could not be found (are you missing a using directive or an assembly reference?)

notge that I have inherited the class library namespace using the 'using' keyword just in case you are wondering. My code is like so:

using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using TQO_Classes ; //importing the class library project
public partial class PageContentMgr : System.Web.UI.UserControl
{
private IContentMaker _data; //this line throws the error, it works fine on aspx pages

Control With Visible=false Cannot Be Used In Javascript?

Jan 3, 2010

I have an ASP.NET text control "FromDate" whose visible property is set to false, but I wanted a client side javascript to be able to toggle the visibility property using CSS properties

element1.style.display = "none"; // hides the element
element1.style.display = ""; // shows the element

but when I attempt to get the textbox, I get null on

var element1 = document.getElementById("FromDate");

When I try the same code with visble=true as the default on the "FromDate" ASP.NET control, it works (although that is not the behavior I need)

C# - UpdateProgress Control Remains Visible On Safari And Chrome?

Jan 18, 2010

I am using the ASP.NET Ajax controls UpdatePanel and UpdateProgress. The idea of a the UpdateProgress control is to display a message while the page is performing a partial postback, then disappear when the postback completes. On Firefox and Internet Explorer, this happens correctly. However, on Safari and Chrome the UpdateProgress control remains visible after the postback completes. Is this a bug in the ASP.NET Ajax Framework, or is there another workaround?

When You first run the project you will see it in the main page...LIke

Logon..it works fine.

The test.. close browser, to test Authentication ticket cookie.

Re run view project ( we are now testing the forms authentication process as cookie is being read to see if authentictaion is still active).

When the page runs, and authenication is active, proven by going to public page IsAuthenticated=true", fine, BUT The page direction usercontrol ( ie logonview control) is not visible, it doesnt work on the new browser run ??

Web Forms :: Setting Visible Attribute On PlaceHolder Control Triggers?

Feb 22, 2011

I have a web form with an Asp.net PlaceHolder control. By default the control is set to visible false and will be displayed through the code behind based on several criteria. In general this PlaceHolder control wraps several other Asp.net controls. Now a new requirement ask that the controls within the PlaceHolder control be visible at all times an no longer hidden. So in the Aspx code I changed the laceHolder attribute and set it to visible. Now all kinds of Java Script validation errors are occuring and it is a horrible spahgetti code nightmare. Is their a way to set the visible attribute on the control and not have it trigger the validation?
