I'm attempting to access data on a parent page from a user control. I understand this is not the best way to go about it and I do not want to get into that debate. This is HOW I have to go about it due to constraints beyond my control and pay grade.I should be able to do this:
myWebBase myPage = (myWebBase) Parent.Page;
int x = myPage.getX();
I'm using the default SqlMembershipProvider,but I've created a custom MembershipUser class (SoeMembershipUser) because I needed a "DisplayName" property.All the DisplayName does is look at the UserName and format it differently.When I try to cast a MembershipUser to a SoeMembershipUser user I get an InvalidCastException.
Exact error is: "Unable to cast object of type 'System.Web.Security.MembershipUser' to type 'Soe.Tracker.SoeMembershipUser'."
Here is the code that fails:
SoeMembershipUser user = (SoeMembershipUser)Membership.GetUser(username); // invalid cast
I have also tried casting later like so:
MembershipUser user = Membershipship.GetUser(username); // ok ... string displayName = ((SoeMembershipUser)user).DisplayName; // invalid cast
Here is the SoeMembershipUser class:
NOTE: I left off the constructors at first, but added them in later when I started having problems. Adding them made no difference.
public class SoeMembershipUser : MembershipUser { public SoeMembershipUser() : base()
I have seen numerous posts with this problem, however none of the solutions have worked for me. I am using asp.net 4.0 forms authentication. I have the following set in my config file.
The login.aspx page uses a master page and styles in a stylesheet located in a folder off the root directory called 'Styles'. I have also add the following to my config file.
When the page displays, the login page displays with the master page content, however all of the styles are missing. When I embed styles into the master page the styles show properly, so I know the problem is that the styles are not being accessed from the file. how I can authorize access to the stylesheet?
if (Context.User != null) { if (Context.User.Identity.IsAuthenticated) { if (!(Context.User is AdministratorPrincipal)) { Admin.Web.Principal.AdministratorPrincipal newUser = new Admin.Web.Principal.AdministratorPrincipal(Context.User.Identity.Name); } } }
to Application_AuthenticateRequest in global.asax file i always get an error when I try to reference it
Unable to cast object of type 'Admin.Web.Identity.AdministratorIdentity' to type 'Admin.Web.Identity.AdministratorIdentity'. protected void Page_Load(object sender, System.EventArgs e) Line 26: { Line 27: this.adminID = ((AdministratorIdentity)HttpContext.Current.User.Identity).AdminID.ToString(); Line 28: }
I did a test and tried to move the code from global.asax to a Page_Load() of webform and worked fine.
I am not able to redirect the user to "SimpleUserLoginAfterRegistration.aspx" page if Administrator is in any one of the .aspx file inside Administrator Folder.
I tried to use: Response.redirect("/SimpleUserLoginAfterRegistration.aspx") But, it is saying Page not found error.
I am feeling that I have terribly wrong somewhere. I was working on a small asp.net app. I have some dynamic themes in the heme folder and have implemented a page base class to load the master page on the fly. The master is having the ContentPlaceHolder like: <asp:ContentPlaceHolder ID="cphBody" runat="server" />
Now I am adding pages that are derived from my base class and added the form elements. I know, Visual Studio has problem showing the page in the design mode. I have a dropdown box and wish to add the event of onselectedindexchange. But it is not working. the page is like this:
I have a div on my master page and I want to use it for showing page errors. I have an error display class and it works fine. My problem is that in some instances, the error gets displayed even before the tag resulting in (non)-display of the message. This is mostly with code that has response.redirect.
I want to counter this by having the error shown on a div within my master page.
How can I access <div id="errorSegment" runat="server">?
I need some help on the row updating for a gridview that i bind manually to a list, not using objectdatasource or sqldatasourcehere is my rowupdating. What i want to do for now is just get the values from the textboxes and I will store them to sting variables then I will call my update function and pass those as parameters. How do I get the data from the textboxes that the user just edited. I have the following but I am getting an error: "unable to cast object of type System.UI.LiteralControl to type System.UI.TextBox
I have implemented rights based security as I describe here: http://forums.asp.net/p/1380280/2916291.aspxThis has been working well for awhile now, but I am moving the site to IIS 7 and encountering problems. I am able to reach the login screen for my app - but upon login get this error: "Unable to cast object of type 'System.Web.Security.RolePrincipal' to type 'RightsLib.RightPrincipal'."As described in the linked post, I have a "RightsLib.dll" that contains the relevant classes like "RightsHttpModule.cs", "RightPrincipal.cs" etc...My app no longer seems to be able to work with RightsLib.dll. RightsLib.dll resides in the bin directory of my app, and I have a reference to it in my project.me what I'm doing wrong, or what has changed to affect this in IIS 7?The only relevant entry in Web.config I'm aware of.
I get this error when trying to export selected rows in gridview to pdf format
"Unable to cast object of type 'iTextSharp.text.html.simpleparser.CellWrapper' to type 'iTextSharp.text.Paragraph'."
This my code below:
using (StringWriter sw = new StringWriter()) { using (HtmlTextWriter hw = new HtmlTextWriter(sw)) { gdfacture.Columns[0].Visible = false; foreach (GridViewRow row in gdfacture.Rows) {
I am trying to pass a collection of Dropdown controls as a parameter to a method which takes a collection of type Control as input. While executing I get the following error:
"Unable to cast object of type 'd__a31[System.Web.UI.WebControls.DropDownList]' to type 'System.Collections.Generic.IEnumerable1[System.Web.UI.Control]'."
I wanted to delete the record from data but I receive this error "Unable to cast object of type 'System.Data.Linq.DataQuery`1[training_eval.Course]' to type 'training_eval.Course'.

This error is occuring randomly, and I can't seem to pinpoint what is causing it. For the most part, the code works fine. I'm confused why it works sometimes, but then suddently craps out on me, lol.It happens in the code when I call upon the asp.net membership provider. It only seems to happen when i use Membership.GetUser() to grab the logged in user's information.
I have installed the final version of Crystal Reports for Visual Studio 2010. I created a new ASP.Net project, saved it, closed it, and then came back to it later. I was prompted to convert the project because of an out of date version of Crystal Reports. But I just created the project...how can the version already be out of date? Also, once the conversion is complete the CrystalReportViewers error stating "Unable to cast object of type 'CrystalDecisions.Web.CrystalReportViewer' to type 'CrystalDecisions.Web.CrystalReportViewerBase'. I am using .NET Framework 3.5 (I cannot use 4.0 for other reasons). Is this the cause?
i have an application consisting of two asp.net projects. And i have have a BasePage which inherits System.Web.UI.Page and have the class some core logic which i require in all of my pages(Implemented in BasePage.cs). So all my pages inherit this BasePage.cs . Now can an Webservice inherit the same class apart from the normal webservice class System.Web.Services.WebService
I might be asking a dumb question, but I have a client for whom I need to build many websites (10+) (asp.net 3.5) which will all the pages on each site will have the same codebehind, but the sites will launching in different regions and whilst following the same template, will have different content.I have built and launched site 1, and sites 2, 3 & 4 is nearly live, but it occurs to me that as all the sites are basically the same, the code is going to get more complicated to update as it will be duplicated, so if I need to do a bug fix on one site, I'll need to do the fix on all websites (and this is going to get complicated.)
I was wondering if it possible to somehow create a class library of all the current aspx.cs files, reference this dll in each website and then inherit these classes into the .aspx.cs files. So default.aspx in each site would still have a CodeFile of "Default.aspx.cs", but Default.aspx.cs would inherit the corresponing class from the dll:
using WebPagesClass; public partial class _Default : WebPagesClass._Default { }
The reason for doing it like this is that if I need to change any code on a specific website (for minor changes in languages for instance), I can override the page functions and change the parts required. For all other pages which have not cha, I can just copy from a single website.Is this vaguely possible? If not anyone one got any killer suggestions of how to manage so many websites from a single codebase?
