Stop Firing Validation Controls
I have designed a form which process database Insert, edit and Delete(datagrid). I input userid,password and privilege in textboxes which has validation controls to verify data keyed in. And press the button to perform insert operation. Upto here is fine.
I want to perform edit or delete operations. I put datagrid for that one. After clicking the Update button for the row, the validation controls are firing again. I need to input some temporary data in the form fields to perform actual update operation. How can i stop firing validation controls at this stage?

if its possible to create a custom validation control which can enable or disable any given control depending on whether a checkbox is checked or not?Currently my solution involves posting back to the form which in turn enables or disables appropriately.
I have noticed with some of the standard validation controls that the screen does not refresh (postback) for the error message to display.Is it possible to enable/disable a control instead of displaying an error message, and do this without posting back to the form to refresh?I have seen some custom controls which can do this for sale, but they cost $$$.

I have two .aspx web pages. The first one has a form with ASP textboxes, validation controls, an a submit button which calls an event handler using VB to insert data into an Access database then redirect to the second page.
Both pages work fine on my local host computer (IIS). But on my remote host, when I click the submit button, it just sits there and does nothing. When I remove the validation controls, the event handler works fine.
How can I get the validation controls to work on the remote server?

A drop down list is populated with certain values from the database and when the selection is changed the post is posted back to itself and ceratin other processing takes place on the same page, based on the selected value.
I have modified the code to make a default list item selection (using option selected etc. ) when the page loads the 1st time. I also want the onChange event to fire the 1st time (by taking this default selected item) on page load, not just when user makes a selection from the list.

For some reason my global.asa file is not firing. I have it located in the
root of my website (e.g., wwwrootmywebsiteglobal.asa) and I have the web
site configured as an "application" in IIS. When I modified the file I also
stopped and restarted the web server.

I'm workinbg in Visual Studio 2003. I'm experimenting with creating a
session variable, and from all I can gather. the Session_Start event is not
firing.
In Global.asx.vb, in the Session Start event, I have the following:
Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
' Fires when the session is started
Session("varTest") = "123"
End Sub
First off, when I set a break point at that line, it is never reached when
the application starts. Secondly, when I try to post a test alert(), to
display Session("varTest"), it comes up blank (no error). Finally, if I set
Session("varTest") = "123" in my asp page, then display it, it shows up, all
of which leads me to believe that the global.asax file is not seen by the
project, even though it was inserted automatically.

Problem with global.asa not firing 100% of the time. This error crops
up several times throughout the day but if you wait a while and reload
the page (could be 5 mins or an hour) it will suddenly start working
again.
The error is:
ADODB.Recordset error '800a0bb9'
Arguments are of the wrong type, are out of acceptable range, or are in
conflict with one another.
/footer.asp, line 101
Line 101 in the footer.asp file reads:
InnovationRS.Open sql, Application("AnymousConnection")
I believe that bad code would produce a persistent error message. The
application would either work, or generate an error 100% of the time,
not be intermittent. The error is now appearing 3 or 4 times a day with
different users reporting it, but like I said, if you wait a while and
refresh the page, it is working again. Code:

My Session_OnStart works but Session_OnEnd does not work. Here's the
code...can anyone tell me what's wrong with my code or if anything else
on the server that needs to be changed. The Session_OnStart does create
the folder for me with the SessionID as the folder name but
Session_OnEnd does not delete that folder. Code:

In the code behind of my ASP.net web page I have code written that is
dynamically creating a button. Here is a sample of how I define it.
//Define Variable
Button btnNext;
public void someMethod()
{
btnNext = new Button();
button += new EventHandler(this.btnNext_Click);
//then i add the control to the page, then call its click event
btnNext_Click();
}
When I clickthis button on the page, the page postsback and its onclick
event is never called (stepping through the code shows that it never gets
reached). If I click the button a second time, the method is called and it
works fine.

Create the following code from database but does not validate on enter - I am using ShadowWizards validation code.
<Input fields so work however I will need dropdown and radio buttons to be validated also.
I really like the work ShadowWizard has put in and would like to continue in the same neat, cleaver coded way!

FormView & DetailsView are great controls in the new version of ASP.Net, but
I am finding it tricky to display more than the record that either control is
bound to at the time. For these controls to be useful in any mode other than
read-only, we need the ability to populate controls like drop downs that hold
associated data, which in the DB represents foreign key related data. In
order to do this, do I create a template field that has a seperate control
that binds to a different data source pulling back the "lookup" data?

I am trying to set up the security for my website... and understand that ASP.NET comes with a Membership Administration tool which is great, does it all for you! however, it stores all the user data (i.e. username password etc) in a default database.
What i would like to do is to GET the user information from this database once a new user is created and store it in my own database - hopefully i will only need the username and password... as then i can link my own user table to my employee table using a user id field? does this make sense???
Basically, i need to know HOW to get this information from the database that ASP.NET automatically creates and add this info into my own User Table.

I have an ASP 3.0 page that contains an ActiveX control that I wrote in VC++ v6.0. Under Visual Interdev I can debug the ASP code just fine. However, when I get to an ASP line that references my ActiveX control the debugger does not go inside my C++ code allowing me to debug the ActiveX control.
If I load the ActiveX control project from VC++ with Internet Explorer as the debug executable I have the same problem. Break points in the ActiveX control's code are not respected. I know I'm compiling in Debug mode,how to get these breakpoints to be respected?
