How to display dynamic XML data inside a Panel control?

In ASP.NET 1.X and ASP.NET 2.0 DataList was the primary control used to display data in groups. In ASP.NET 3.5 we have a new control that takes care of grouping data. In this article we are going to demonstrate how to group data using the ListView control.

Charts and graphs always attract more users to the website. Displaying statistical data in the form of graphs gives more meaning to the data. There are tons of third party controls that can be used to create impressive charts but almost all of them come with a price. In this article I will introduce a very simple charting control, WebChart which allows the developer to create really cool looking graphs with only few lines of code. The best thing about this control is that it is totally free. The article will focus on creating the SmoothLineChart and the PieChart.

An approach to displaying a "please wait" message/animated gif following a button click using encapsulated client-side JavaScript.

It is often useful upon a form submission in a web application to display a "please wait" message, or animated .gif image, particularly if the submission process lasts a few seconds or more. I recently developed a survey submission application in which internal users upload excel spreadsheets through a web page. The application inserts the uploaded data from the spreadsheets into a database. The upload/insert process may only take a few seconds, but even a few seconds on the web is a noticeable wait. When testing, some users clicked the upload button repeatedly; it was useful to provide a visual clue that the upload was underway. For that matter, it was useful to hide the upload button altogether, preventing multiple clicks. The control presented here, a subclass of the Button control, demonstrates how client-side JavaScript code encapsulated in an ASP.NET server control can provide such functionality conveniently.

Selecting multiple checkboxes inside a GridView control has been lot in discussion but I was unable to find any solution to following problems:



If page has two or more GridViews?
If Gridviews are in usercontrol?
If page has a Masterpage?

So to sort out these problems I picked an article that was of great help "GridView CheckBox Selection With a Twist". And here are few changes

The ASP.NET GridView control is the successor to the ASP.NET DataGrid control which has many built in functionalities like paging, sorting, editing or deleting data. In this article I will explain how to select checkboxes inside the GridView control.

Many times you want to select multiple columns in a DataGrid and highlight the columns selected.

In the DataGrid MouseDown Event you will find out if you have selected a column header through the hit test. You then find the co-ordinate of the column and construct a rectangle out of that. If you are selecting multiple columns you can store the index of the columns and the rectangle in ArrayList.

Make sure you clear the ArrayList when you HitType is None.

In this article, you will learn how to work with the GridView control using the data from a Microsoft Access database. I will examine how to perform advanced tasks such as displaying, sorting, paging, updating and deleting data using one of the powerful controls included with Visual Studio 2005 in a step-by-step manner.

This article is taken from the book C# in Depth, Second Edition. This segment looks at what it means for code to be dynamic, and the syntax involved in using dynamic typing in C# 4

you can use javascript confirm() dialog for asking user confirmation to delete records or not?

Hi,

I would want to know what is better: to keep a lot of data in cache at once or to keep a little data by paging?

 

For example:

I have 1000 articles and 200 pages.
