For example lets say I want only admins to be able to see and edit CustomerID in details view, moderators can see this value but it is not editable, and regular users cannot even see it.
View 2 RepliesI have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.Here is the membership provider definition from web.config:
<membership defaultProvider="MyProvider">
<providers>
<add name="MyProvider"

View 2 RepliesI've got a DetailsView which has some static fields defined in my markup and adds some extra fields dynamically in the VB codebehind. It should be noted that the DetailsView lives in an UpdatePanel.Assume that I would like to get inventory information for a number of warehouses, but I only want to see those which have stock on hand. In addition I have some static information such as product, sku, etc.
The problem I was having was that every time I clicked the "Details" button it would just keep appending the dynamic fields to the end and never re-rendering the table. I figure I either need a conditional or to tell it to re-render somehow. I suspect this problem arises from my use of the UpdatePanel but it's important for the user experience of my customer to keep this.

Dim stockDT As New DataTable
For Each row As DataRow In stockDT.Rows 'Add column for each Warehouse that has stock

I have a DetailsView which has two fields - one that is visible, one that is not. The first the user fills out, the second I want to auto-populate. Unfortunately, I haven't been able to find a way to set the value in this second invisible field. I've tried adding code like this to the Page_Load:
If Not IsPostBack Then
DetailsView1.DefaultMode = DetailsViewMode.Insert
Dim txt1 As TextBox = DirectCast(DetailsView1.FindControl("Type"), TextBox)
txt1.Text = "administrator"
End If
But this returns an error of "Object reference not set to an instance of an object." Any ideas on how to accomplish this - either using the method above or another method?The hoped for end result is that when a new record is inserted via the DetailsView that this record will include the username (entered by the user) as well as the "type" of "administrator"
I'm developing a "small" warehouse-management WebApplication for few users(5-10 parralel) but with a complex authorization system(checking if pages,menus,TabPanels, UserControls and even single controls are visible or enabled) and permanent and frequent access. Because i've only limited experiences with the ASP.Net MembershipProvider, i'm unsure what's the best approach for following goal:
I want to hold all users, roles and frequently used masterdata in the Cache(in a Dataset). Hence every readonly access should be faster and causes less traffic than always using the database. On updates,deletes and inserts i would update the cached dataset and also the database.
Can i use or extend the SqlMembershipProvider to achieve this goal and if possible how?

I have a number of lines of text on an .aspx page that I want a user to be able to edit, I am not storing this text/information anywhere in the database. I just want it to be information that is displayed to the user but can be editable, so the user can view the text and if there is a mistake or want to make a change they can do this by editing it.
I have seen that if you display data in a label and put a textbox beside it then, the textbox can move into the place of the label - I have done this for other text on the page however that method would not fit for this purpose because I require this edit of text to be for a number of lines.

View 2 RepliesAll I want to do is build some kind of table-like or grid-like control in my form that has two columns. An element in the first column should be a checkbox that is changable by the user, and an element in the second column is some un-editable text. Of course, when the user checks or unchecks a checkbox, I have to be able to handle that event and figure out which row it came from.I've been trying this all day with no luck. Do I use a ListView or a DataGridView? If the answer is DataGridView, do I add columns and rows to it directly or do I try to make a DataTable which I then assign to the DataGridView's "DataSource" property?Is is possible to make editable checkboxes in a DataTable? I succeeded in making checkboxes by making a DataColumn of type boolean, but then I couldn't check or uncheck them during runtime.

i have a given table structure with some data inside. Here is the database model: Database Model..In the TBL_SCENARIO Table a user can store an unlimited number of scenarios. In the TBL_EVENTS can each scenario have an unlimited number of so called Events like risks.The TBL_EVENT_DATA Table stores now for each day and for each event in a scenario the value min and max.I would like to edit a scenario with its events (! not an single) in a GridView Control. Is this possible? I would like to have the rows as days and the columns (2columns for one event) as min max value for the events. So is it possibel, when i have 5 events, have these in 10 columns (2 columns for each event [min] and [max] and then the days as rows?

View 14 RepliesIn my first attempt to create a Class that contains something useful (if you will), I am a little lost what a sound way to proceed is. I am trying to make a table that has fields and records. Perhaps imagine a tiny spreadsheet. So, I create my Class. Properties might include the number of columns, the column titles, and the number of rows or records. I then think the thing to do is create a couple of structures to be used within the class. Thus far I have this:
Imports System.Console
Public Class ConsoleTable
Property NumberofCOlumns As Int32
[Code]....
Problems I am creating in my mind include:
1) In the Field Structure, could I make the FieldValue so that I can change the data type? Meaning sometimes I want an instance of a Field to hold a string,or an integer, or a decimal.
2) In the Record structure, for any given instance of one I don't know the number of fields it will hold until I create the new instance. I tried Public RecordFields(FieldCount) As Field in the Structure, but that's not allowed.
I then used Public RecordFields() As Field, and then in my code used the ReDim method. Is there a better way?
3) With the Table Class, same problem. The number of records within any instance of the class needs to be dynamic.
look at this picture of my index form. It's resized, now you can't see the full labels text.

I have written a program and everything works fine, but I want to make sure that only the administrator can add or edit users to the system.

[Code] I have tried putting my If statement in but it doesn't happen the button is still active even when I login as admin.
