Security :: Get Custom RoleProvider To Invoke Its Methods On Every Page Load
Jun 18, 2010I had a post here [URL] that I need to expand on now. I have a few web pages that need to check for a certain role on each page request. I have a custom Membership Provider and a custom Role Provider (called CustomRoleProvider - very original - I know) that I am using to do this. When a user logs in, the CustomRoleProvider.GetRolesForUser() method is called automatically (by the urlAuthorizationModule). When this method gets called, I am currently adding a role to the roles string array that allows/permits the user from viewing the web pages of concern based on certain qualifications that are determined elsewhere in the code (i.e. the database is queried to see if the user has rights to visit certain pages).
This approach only gets me half way because the user's roles are only checked once at login. When I wrote my previous post, I thought the CustomRoleProvider was broken because it wasn't calling the IsUserInRole() method on each page request. According to Microsoft, "The IsUserInRole method is called by the IsUserInRole method of the Roles class to determine whether the current logged-on user is associated with a role from the data source for the configured ApplicationName." (that information comes from this page:
[URL] Reading that description I thought it was being called automatically on each page request. This is not correct. What I need to know how to do is to get a method in the CustomRoleProvider that returns a boolean to be called automatically on each page request so I can update the user's roles if they change while the user is logged into the web site. For example, if the user has rights to visit page A and then five minutes later his rights are revoked, he can't visit page A again unless he contacts an admin to reset his rights.

Jan 19, 2011I have UserControl that has asp control(<asp:Button runat="server" ID="btn" />) and I want to render it.
I tried 1
[Code]....
It doesn't works because it says that each control that has runat="server" must be in Form.I also tried 2:Because loader.Form is null, I create HtmlForm and added the ctrl to it and then added HtmlForm to loader's Control, BUT it says that it has 2 HtmlForm. So, instead I "injected" HtmlForm to loader like this
[Code]....
Now no error is occurred, BUT StringWriter is empty. don't tell me to add Page to solution and override OnRender. I want to do it as I mentioned above.
Web Forms :: Dynamically Load Usercontrol On TabClick?
Nov 16, 2010When it comes to the usercontrol specially when they are loaded dynamically on the basis of certain conditions then it becomes a very confusing work. I have read in many forums that the dynamic controls have to be loaded in OnpreInit or OnInit. Some of those links are[URL] But this is useful only when if the we know that we have to load UserControl1, UserControl2 without considering any conditions. But what if I have a Tab control and for each Tab Click I have to load the UserControl dynamically. In that situation how can we add the control in either OnPreInit or OnInit. If I am not mistaken then in such case, then we can add usercontrol in certain events. If we are using a TabControl then we load in Tab_Click , if we are using Menu Control then we use Menu_Click and depending
upon the particular tab or Menu we load associated usercontrols. Hence in these conditions, how can we go with the logic mentioned by above links. I have this confusion for very long time . I am posting little portion of my project here. I am using RadTabControl but it doesnt matter if it is Microsoft TabControl. In the aspx, I have a code to define RadTabControl.
<telerik:RadTabStrip
ID="tabMemberDetails"
runat="server"
Skin="WebBlue"
MultiPageID="tabDetails" SelectedIndex="0"
Align="Justify"
ClickSelectedTab="true"
EnableViewState="false"
ReorderTabsOnSelect="true"
Width="1139px"
OnTabClick="tabMemberDetails_Click" ScrollChildren="true">
</telerik:RadTabStrip>
In the code behind, I am loading usercontrol on the basis of the particular TabClick. tabMeberDetails_Click fires whenever I click on the tabs.ViewState["ControlName"] stores UserControlName on the basis of certain condition and finally i load the usercontrol.
proteced void tabMemberDetails_Click(object sender,
RadTabStripEventArgs e)
{
Conditions......
{
ViewState["ControlName"]=........
}
viewDef=ViewState["ControlName"]
UserControl control = (UserControl)LoadControl("~/Controls/"
+ viewDef + ".ascx");
after this I add control to the RadTabStrip.................. and call bind method.........
}
As you can see from above, I am loading my usercontrol in tabMemberDetails_Click event. I see no other choice to do it in OnPreInit. Can anyone answer if this is the right way to do or there is another way that complies with the logic in the links given above.

View 1 RepliesWeb Forms :: Dynamically Load UserControl, Access Properties In Parent Page Without Recreating In PostBack
Nov 15, 2010I have several usercontrols which are loaded based on business logic.However, all of them have webcontrols whose selected/entered value needs to be accessible in parent page on an event.Since there can be any combination of UserControls, I do not want to load all the UserControls in the Parent Page, since they are heavy.
I would like to load only those controls which are supposed to appear on the page, yet access the value from the usercontrol which caused the postback. (I would rather not access using Request.Form) (ViewState is open, but unsuccessful to store value in parent page's viewstate in onClick)Here is a sample scenario
Page: Home
Dynamically Loads: UserControls1
UserControls has TextBox tb and Button btn, causing onClick
When btn is clicked, I want to get value of tb in parent page on PostBack, Page creates UserControl2

Using Javascript Inside A Dynamically Load UserControl In JQuery Ui Tabs
Jan 25, 2011I need to insert some JavaScript code inside a UserControl that I load from an Ajax call via jQuery Ui Tabs. Let me explain... This is my View (with jQuery loaded)
<script type="text/javascript">
$(document).ready(function () {
$("#tabs").tabs({
cache: false,
});
getContentTab (1);
});
function getContentTab(index) {
var url='<%= Url.Content("~/Home/getUserControl") %>/' + index;
var targetDiv = "#tabs-" + index;
$.get(url,null, function(result) {
$(targetDiv).html(result);
});
}
</script>
<div id="tabs">
<ul>
<li><a href="#tabs-1" onclick="getContentTab(1);">Nunc tincidunt</a></li>
<li><a href="#tabs-2" onclick="getContentTab(2);">Proin dolor</a></li>
<li><a href="#tabs-3" onclick="getContentTab(3);">Aenean lacinia</a></li>
</ul>
<div id="tabs-1">
</div>
<div id="tabs-2">
</div>
<div id="tabs-3">
</div>
</div>
With these lines of code I call the Ajax function to load the content into a DIV.
This is the Action from the controller:
public ActionResult getUserControl(int num)
{
return PartialView("TestUC", num);
}
And this is the UserControl...
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
Number... <span id="testSpan"><%=Model.ToString() %></span>!!
<input type="button" value="Click me!!" onclick="message();" />
<script type="text/javascript">
function message(item) {
alert($("#testSpan").html());
}
</script>
The problem is that the message() function returns always 1 (instead of returning the correct number). My question is... How should I add the script to my UserControl in order to have my code running correctly?

MVC :: Load Partial Views Dynamically At Runtime Using Html.RenderPartial?
Jun 8, 2010The following link describes the relationships between a Partial View and its parent in terms of ViewData: [URL] In relation to the text: "A partial view enables you to define a view that will be rendered inside a parent view. Partial views are implemented as ASP.NET user controls (.ascx).
When a partial view is instantiated, it gets its own copy of the ViewDataDictionary object that is available to the parent view. The partial view therefore has access to the data of the parent view. However, if the partial view updates the data, those updates affect only the partial view's ViewData object. The parent view's data is not changed"
how the parent view can make use of the new data added or existing data changed and updated, by the partial views? My question is around how to load partial views dynamically at runtime using Html.RenderPartial(...) whilst having one version of the data used and updated by the parent view and it's children.

UpdatePanel Dynamically Loaded Web UserControl Will Disappear After Clicking Any Button Inside The UserControl?
Mar 17, 2011I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.
