I’m having and issue firing code behind on one of my asp buttons.
Screen Shot 1 - http://beta.sdsna.com/ModalFiles/ss1.jpg - Prior to clicking the update button
Screen Shot 2 - http://beta.sdsna.com/ModalFiles/ss2.jpg - Box after clicking the update button, no event behind was fired
Project Files - http://beta.sdsna.com/ModalFiles/AJAXModalPopup.zip
Project Overview:
I have one list page (UserList.aspx) that contains a ModalPopupExtender. An ascx control (ModalContainer.ascx) loads within that ModalPopupExtender and retrieves a few parameters set by the list page. Based on one of the parameters, the ModalContainer.ascx control dynamically loads in another ascx control. The control that gets loaded in could be to edit user, add user, etc.
Everything works fine except on the last ascx control that gets loaded in. On that control I have an asp submit button which should fire code behind but does not.
UserList.aspx
UserList.aspx contains an add user button which calls a JavaScript function ShowModalPopup and accepts up to 4 parameters. When this function is called it sets global JavaScript variables of the passed parameters and then opens up the ModalPopupExtender which has the ModalContainer.ascx control inside.
ModalContainer.ascx
When the popup extender is opened the ascx control has a JavaScript function for pageLoad(). The pageLoad() function does $find(“ModalPopupExtender”).add_shown(SetPostBack);.
The SetPostBack() function does the following – gets the global JavaScript variables and inserts the values into hidden text box fields and then fires btnPostBack.click(); which is a hidden button on the form.
I have an update panel with the ContentTemplate having an ASP:Placeholder and the Trigger being btnPostBack with EventName=”Click”.
So when this button is clicked, the code behind reads the values in the hidden text boxes and loads into the ASP:Placeholder the proper ascx control – it being UserEdit.ascx for this example.
UserEdit.ascx
This control contains 3 ASP:Textboxes, UpdatePanel and ASP:RequiredFieldValidators. In the code behind page load event I again read the values in the hidden text boxes and populate the form from the database.
The purpose of the update panel is when the user clicks the update button, I validate that the username is not already taken and if it is I show a message label that is in the ContentTemplate of the update panel.
All of the above works fine except when I click the update button. On clicking of the update button it does not fire the Click event in the code behind. Instead it basically closes itself and what I am left with is a blank modal popup.
The RequiredFieldValidators do work - just the code behind event does not. Removing the validators does not fix the problem either..
Any idea’s or how I should approach this in a different manner to accomplish my goal?

I am accessing a FORTRAN dll into ASP.Net 2005. The dll is taking input from a .dat file after processing it generates another .dat as an output. Here's ASP.Net is working as an interface of Input(by which user can supply input file) and Output(by which user can see the output in various listbox, textbox,etc).
I used importdll atrribute to declate DLL, and used call keyword to call the function of DLL. The program is working fine when i am executing using .NET IDE. but when i published the application it doesn't work. ASP.Net Application stops IIS on function call of FORTRAN dll.

hi,
Can any body please help me? When I am opening the asp.net configuration it giving me this error as follows.
Provider Management
Could not establish a connection to the database. If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider.
What I need to do to connect to sql server. I have already installed sql still its showing me this error.

I think you are trying to do any personalization or membership kind of operation.
Do one thing
From VS Command Prompt - > Run aspnet_regsql Command
This it will as for the data base and give the database server name . It will create some personalization table and procedure on your database.
Hope then your problem will be resolved !!!
Thanks

This is because of the fact that Mail Server sets the maximum size to send/accept the attachment.
If its over its limit, it fails...

How about using a session variable instead? Then you need not worry about the query string at all.

Try to put dropdownlist out of UpdatePanel and check if index of ddl return to 0 again.
Does the ddl have autopostback property to true?

Hi , i am developing an application in which
1. An Admin register a company(he can register any number of companies), and assigns a Administrator to it.
2. This Administrator then creates a Role Hierarchy for eg manager, deputy manager , consultant according to his company hierarchy and assigns user to any of this Role and set of pages .
3.No low role user can access high role user pages but vice versa is possible for eg. Manager can access deputy manager pages but dm cannot access manager pages.
(THIS WHOLE PROCEDURE IS REPEATED FOR EVERY COMPANY)
4. Now i want to implement Role and Authorization Api in this, how can I implement that
Please suggest me any ides if u have any
