Web Forms :: Detect Page Load Completion?
Jun 22, 2010Detecting Page load Completion? How could we do this using jscript or jquery, would it be possible? Kindly give your views and ideas. I have an asp.net web page, which is huge and takes time to load. If the user clicks on any buttons on the page, before the page completes it's load, we get error messages. Since some of the hidden field values in the page, have value=0 because the page did not complete it's load. I hope I was clear with my question. Meanwhile I need to work on improving my code to process quick.
I do have an update panel, on my page.
Detect Client-side When A Page Load Is The Result Of An AJAX History Point?
May 25, 2010I'm trying to prevent a "flicker" effect that is occurring on my ASP.NET page which occurs when a user navigates to the page via the browser back button after having navigated away from it. The reason for the flicker is that I'm using an Update Panel which has some content in there on the initial page-load. As a result, when the page is loaded via a back button that initial content is shown very briefly before it is updated with the correct History-aware data.
In order to overcome this I am intending on having the updatepanel hidden (display: none) on inital page load and then show it as long as we don't have any history to deal with. The problem is that I can't find out what to check to determine if there's any history. I can see that the Sys.Application has a _history member but when I'm checking it on page init it is null each time.Does anyone know what I should be checking to determine if there's history to deal with for a page load client-side? And at what point to do it?

HttpHandlers / Modules :: Generic Handler / Prevent Data From Being Written To Live Table Via The Live.aspx Page?
Jun 28, 2010I am using a generic handler (indicator.ashx) to create a graphic that is overlayed from information from a table (called LIVE) from our SQL database. This is working very well and I am very happy with the results.
However I am having an undesirable issue where the query string that is used for this is also being accessed by another page (called ReceiveLive.aspx) which is populating our LIVE table with data when we don't want this. I have been able to track this issue down to our generic handler that seems to populate this table with data whenever the handler is accessed.
The query string that is used to access our graphic through our generic handler is
http://mydomain.com/indicator.ashx?ID=ABC001.
Our other page that writes data to our LIVE database used the query string
http://mydomain.com/live.aspx?ID=ABC001 which is normally only accessed by a small piece of software that sits on the users PC and sends the data when necessary.
My question is this: How do I prevent data from being written to our LIVE table via the Live.aspx page everytime a query string is processed by my indicator.ashx is accessed?
Forms Data Controls :: Custom PagedDataSource Created At Page Load?
Jan 29, 2010I have a custom PagedDataSource created at page load.I have created two lin button "Next" and "Prev" to navigae the data source.I am using session to store the PDS and retrive it on each page load .I am incrementing CurrentPageIndex each time by 1 in the buttonNext click event and setting the value to the pds object.
What i am trying to do is, when the page loads, if page currently showing is last index, disable the "Next" button. The problem is, everytime I have to click "Next" one more time to make it disabled. It seems, the page does not recognize that it is the lastindex of the datasource when loading. When I click again one more time while in the last page , it is disabled.

Custom Server Controls :: Add This Control To The Page,an Alert To Check The Text Value Of The Custom Control?
Dec 20, 2010created a Custom Textbox Control that is intended to be a "masked date" textbox, so that I can handle different ways a user might enter in a date and make it work no matter what.I did this by creating a custom control with 3 separate Textboxes one for month,one for day one for year,then do some handling for different things that could be entered and it would all work.
The problem I am having is,when I add this control to the page,if I do an alert to check the Text value of the custom control it just gives me "[ServerControl1]" even if I enter in a date.
I tried doing an AutoPostback after entering so that it would refesh the Viewstate to have the values of the textboxes but the control doesnt seem to actually postback, even though I have it enabled.accessing the Textbox value after someoen
has entered a date?first custom control I have created and have been using google.
My Server Control Code is as follows:

Custom Server Controls :: How To Get The Value Of Readonly Properties Of Server Controls Inside A Custom Server Control
Apr 4, 2010I have a custom server control inheriting from CompositeControl. It consists of two RadioButtonlist controls that are rendered side by side in an html table. The number of ListItems in each RadioButtonList is not known until runtime. Depending on how many items each list contains, the RepeatColumns property of each list is set differently. To do this in the handler for the ItemDataBound event I need to get the count of ListItems in each RadioButtonList. How do I expose the Items.Count property of each internal RadioButtonList as a top-level property? I tried using a getter to return the count but this generates a compile-time error to the effect that the count cannot be assigned to--even though I have not created a setter.
Similarly, in the handler for the Submit event, I need to get the ClientID of each internal RadioButtonList to pass to a method that checks for data changes. How do I expose the ClientID of each component RadioButtonList as a top-level property?
I can of course index the Controls collection of the composite control to access the child control and read its properties--but that defeats the whole point of making a complex, independent custom server control.

Custom Server Controls :: Custom Composite Control With Custom Templated Child Controls?
Mar 22, 2011I am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:
[Code]....
I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:
[Code]....
I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.

View 1 RepliesSecurity :: 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.
