ASP.NET Charting Using Office Web Components (OWC) By Olav Lerflaten Introduction A common requirement when developing applications is to provide some interactive charting.
For example, you may be developing an application that helps managers maintain sales or production data. This data might be stored in a SQL database, and your application might allow for users to add new information and update existing information. In addition to these order-entry features, management might request that they be able to visualize this data graphically using pie, bar, and/or scatter (XY) diagrams. From a Windows desktop application, this has never been a problem, as there are many graphical libraries and charting components available. Accessing and Updating Data in ASP.NET: Programmatically Accessing Data using the Data Source Controls. By Scott Mitchell.
Data Binding Microsoft Chart Control - Alex Gorev's Weblog. I'd appreciate your help so very much.
I'm sorry but I have error in this code. Can you help me? Private void Page_Load(object sender, System.EventArgs e) OdbcConnection myConnectionString = new OdbcConnection(ConfigurationManager.ConnectionStrings["ConnMySQL"].ConnectionString); Using Microsoft's Chart Controls In An ASP.NET Application: Getting Started. By Scott Mitchell Introduction A picture is worth a 1,000 words...
This adage rings especially true when it comes to reporting. Charts summarize and illuminate patterns in data in a way that long tables of numbers simply cannot. Web developers have long searched for ways to express numerical data in a graphical format; until recently, doing so required the use of an open source or third-party charting or reporting package or some homegrown technique using HTML, GDI+, or some other technology.
Getting Started with the ASP.NET 3.5 Chart Control - Dan Wahlin's WebLog. I think it’s safe to say that charting is a key part of many applications run on company Intranets.
People like to see data visually as opposed to viewing it in rows and columns sometimes (especially higher level managers). While there are many 3rd party solutions available that provide charting solutions, you now have access to a very powerful solution from Microsoft that won’t set you back any $$ at all.
Translated…it’s free! Sure, some of you may think that “free” products aren’t good but that’s not the case here. Using Microsoft's Chart Controls In An ASP.NET Application: Sorting and Filtering Chart Data. By Scott Mitchell Introduction The Microsoft Chart controls make it easy to take data - such as sales numbers, website traffic statistics, and so on - and turn it into a chart, which can be saved to an image file or displayed from a web page.
In Plotting Chart Data we examined a myriad of ways to turn data into a chart, including: plotting the chart data point by point; binding data to the Chart's Points collection; programmatically binding data structured data to the chart; and declaratively binding data using one of ASP.NET's data source controls, such as the SqlDataSource or ObjectDataSource. Oftentimes, web pages that display charts include user interface elements that let the user filter or sort the plotted data. For example, when viewing a chart of expenses, the user may want to only show expenses between two dates, or may want to sort the expenses by category. Samples Environment for Microsoft Chart Controls - Release: Samples for Chart Control - .NET Framework 3.5 SP1. Axis Scale. This topic demonstrates how to work with axis scales.
Both the Minimum and Maximum axis properties can be set to a specific value, or they can be set to Auto, which is the default. If the minimum and maximum values are set to Auto, then depending on the axis, automatic scaling will determine their values from X or Y data point values. If the Margin property is set to True which is the default, then automatic scaling will add a "gap" or an axis margin between the last data point and the border of the chart area. The size of this margin is determined automatically. Both axes and their associated grid lines, tick marks, and labels have Interval, IntervalOffset, IntervalType, and IntervalOffsetType properties. The properties of the axis elements (e.g. major grid lines, etc.) are given higher priority as compared to the Axis properties. The minor grid lines and tick marks of an axis never have their interval-related properties affected by the property settings of the parent Axis object.
New ASP.NET Charting Control: <asp:chart runat="server"/> Microsoft recently released a cool new ASP.NET server control - <asp:chart /> - that can be used for free with ASP.NET 3.5 to enable rich browser-based charting scenarios: Once installed the <asp:chart/> control shows up under the "Data" tab on the Toolbox, and can be easily declared on any ASP.NET page as a standard server control: <asp:chart /> supports a rich assortment of chart options - including pie, area, range, point, circular, accumulation, data distribution, ajax interactive, doughnut, and more.
Recovering and Changing Passwords (VB) ASP.NET includes two Web controls for assisting with recovering and changing passwords.
The PasswordRecovery control enables a visitor to recover his lost password. The ChangePassword control allows the user to update his password. Like the other Login-related Web controls we've seen throughout this tutorial series, the PasswordRecovery and ChangePassword controls work with the Membership framework behind the scenes to reset or modify users' passwords. Introduction Between the websites for my bank, utility company, phone company, email accounts, and personalized web portals, I, like most people, have dozens of different passwords to remember. ASP.NET Authorization. The topic you requested is included in another documentation set.
For convenience, it's displayed below. Choose Switch to see the topic in its original location. Authorization determines whether an identity should be granted access to a specific resource. In ASP.NET, there are two ways to authorize access to a given resource: The following shows the syntax for the authorization section: The allow or deny element is required. The allow and deny elements grant and revoke access, respectively. The following example grants access to the Kim identity and members of the Admins role, and denies access to the John identity (unless the John identity is included in the Admins role) and to all anonymous users: The following authorization section shows how to allow access to the John identity and deny access to all other users: You can specify multiple entities for both the users and roles attributes by using a comma-separated list, as shown in the following example: Rules are applied as follows:
Menu and SiteMap Security Trimming (plus a trick for when your menu and security don't match up) - Jon Galloway. Summary ASP.NET 2005 introduced a pretty solid menu which is integrated with a configuration driven sitemap. The cool part is that the menu can be hooked in with your security roles, so you don't have to worry about hiding or showing menu options based on the user - the menu options are automatically kept in sync with what the user is allowed to see.
