It's happening because the js and the codebehind only ever exist together when you're developing...normally, the codebehind exists on the server, the javascript in the browser. So when the browser encounters your mouseover attrib, it looks for Showbigdiv somewhere on your page. Since it's not there, (it's on the server) it can't find it, so Expects an object.
There are a couple of ways to get around this - you could make an out of band call to the server to get the data that you need, or if a postback isn't a problem, I tend to put a nmormal asp:button on the page, with its OnClick handler pointing to Showbigdiv, and visible set to false. Then in the page, define a javascript function similar to:
<br />
function handleMouseOver(()<br />
{<br />
document.getElementById (myAspButtonClientId).click();<br />
}<br />

Hi,
Is there a way where I can set a button to validate ONLY 1 control? Instead of the whole page? I dont mean validation controls.. I mean "Causes Validation"
Thanks.

Dear All,
I created a web application using vs2005 and this is my problem
I want to control access per page and per user basis, futhermore i will do on groups basis later
What i want to do is to create a webfrom for the admin that lists all the webforms of the web application in a checkbox list or a lisbox control.
So after the admin picks a user he sets the "Allow/Deny" the user access to the page by checking or unchecking the items. I will later save to the database.
I installed the aspnet db to create and manage the users and for security but it only gives permissions per folder not per page so is there a way to exploit it?
So what i need is to know how to list the pages and how to manager security
Any keys would be apriciated
Thanx in advance
Best Regards

You can do it in the following way:
You have a User Table: (UserID, Username, UserGroupID)
You have a UserGroup Table: (UserGroupID, UserGroup Description)
You have a Permissions Table: (PermissionID,Description)
You have a Link Table between the Permissions and the UserGroup: (UserGroupPermissionID, PermissionID, UserGroupID)
Lets say you have only 2 user groups: General User and Admin.
A user can be SET to be any of the 2 UserGroups.
Lets say you have 2 Webforms. Webform1 is for General Users and Webform2 is for Admin. Consider each webform like a seperate permission. So lets say Webform1 is PermissionID 1 and Webform2 is PermissionID2:
Permission Table:
=================
Permission ID ... Description
1 ... Webform1
2 ... Webform2
UserGroup Table:
================
UserGroupID ... Description
1 ... General User
2 ... Admin
UserGroupPermission Table:
==========================
UserGroupPermissionID ... UserGroupID ... PermissionID
1 ... 1 ... 1
2 ... 2 ... 1
3 ... 2 ... 2
So you can see from that table that General User is allowed permission 1, whereas Admin is allowed permission 1 AND 2.
After you set the figures in the database, At the top of Webform1 code-behind page, you will need to query the database by passing the session UserID. Use a VIEW of the Permission link table and the usertable. If the UserID has permission "1", then allow him to see Webform1. If he doesn't, then redirect him/her.
Do the same for Webform2. If the user doesn't have Permission "2" in the database, he will simply be redirected away.
HOPE THIS HELPS!

It is a very straighforward but very very long problem to describe. Please, rephrase your question to make it more precise.

I'll explain what I did:
In addition to the above post, I had a webform which had a datagrid that displayed ALL the records for the different permissions which I have defined(recall Permission Table). Remember that EACH Permission represents a Webform, so there is no need to list the page. You can make the Datagrid entries hyperlinks to the weforms if you like.
You can add/edit/delete all the Permissions which you have on that particular webform, just like you can add/edit/delete user records and such, BUT.. EACH webform, EVEN the Permissions webform, will have hard code which will give different users access/denial.
for instance, lets say that in the Permissions table, you have the following record:
PermissionID = 9
PermissionDescription = Permission Webform
and the Admin User Record is:
UserID = 1
Username = Admin
UserGroup = 2(i.e. Admin)
and the UserGroupPermissions Record(in the LINK table) is:
UserGroupPermissionsID = 3
UserGroupID = 2(Admin)
PermissionID = 9
This means, logically, that the admin is linked to PermissionID number 9.
Now lets go back to the webforms. In the PageLoad even of the Permission Webform(which is what you are asking about), you will HARD CODE the following:
After creating a VIEW of the tables which show a link between Admin and the Appropriate PermissionID for the Current page, you will pass the UserID which should be stored as a Session variable as soon as any user logs in. Pass that ID through a SQL query and check whether the UserID in the Session variable HAS the Permission ID of the link table... IF YES, then Load the page, IF NO, then redirect.
You are asking about the webform itself I think. The Webform itself for this will be the same as any other webform for adding/editing/deleting records. Use a datagrid which should be bound with the information from the appropriate TABLES or VIEWS.
When you create a New Permission, like SiteMap Page Permission, you will HAVE TO HARD CODE the permission authorisation as described above, but this time for the SiteMap page.
I hope this answered your question.

Hi All,

You've just got to figure them out individually. they are going to be slightly different - Firefox tends to be more standards compliant.

When pages render differently in Internet Explorer 6 and Firefox, it's almost always Firefox that renders them correctly. It's a common misconception that it is Internet Explorer that is the standard just because it's the most commonly used browser at the moment, while the truth is that there are several bugs in IE 6 that makes it render pages incorrectly.
When it comes to form fields, you will never get them to render exactly the same in different browsers and in different operating systems, as it's not defined in the standard exactly how form fields should be rendered. One method that I have had some success with is setting the width of the field to 100% and putting it inside an element with an absolute width.

I want to select some criteria on on page and according to that criteria second page should be displayed.
Means there are some drop down lists on one page in which some columns of database tables are retrieved and based on that on the next page it should show that critera as well as should have provision to add some data so that it will again send back to the database in proper table.
There are five tables with one unique id and the description or name and there is one table having seven fields or column to save its unique id, five ids from the previous database tables and the description field which has to be filled after selecting criteria.

You can store information in Session or Cache.
But put there only the required information, in order to save the memory.

{
ViewState V1 = ViewState.TextOnly;
}
But I am not able to find the namespace and assembly for 'ViewState' class.
What to do in this case ?
