But the same report when I retrieve through ReportViewer builtin webpart. Its displaying without any issues. How do I fix such issues?

Displaying SharePoint lists in Web Parts

When you create a built-in or custom list in Microsoft Windows SharePoint Services, Windows SharePoint Services creates a Web Part, a basic building block of a SharePoint site, to display that list. These Web Parts are called List View Web Parts. Windows SharePoint Services stores List View Web Parts in the site collection Web Part gallery. (The site collection Web Part gallery is the most central gallery of Web Parts for a work group. By default, the gallery name is the name of the site, such as "Our Team Site Web Part Gallery." )

Windows Service Applications Tutorials

You can easily create services by creating an application that is installed as a service. For example, suppose you want to monitor performance counter data and react to threshold values. You could write a Windows Service application that listens to the performance counter data, deploy the application, and begin collecting and analyzing data.

Displaying Row Details Tooltip on GridView using JQuery

Continuing exploring JQuery! I decided to implement a feature to display some kind of details related to a row displayed on GridView. For example when displaying employees details on GridView some information might not fit in the GridView because it will make it huge and wide. These infomration can be diplayed as Tooltip. Or when you want to display a picture and some kind of formated text to be diplayed as tooltip when mouse hover on the image.

Using ASP.NET 3.5's ListView and DataPager Controls: Displaying Data with the ListView

Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!

WCF Tip: Using Properties in Service Contracts

you'll notice all of the Service Contracts are implemented with interfaces containing only methods. For the longest time I thought that's all that was supported, until I thought about it a little more. In C# land, properties are simply wrappers around a get method and set method, so why wouldn't we be able to use properties in a service contract? Well the answer is we can.

Realizing a Service-Oriented Architecture with .NET

This article is meant to be a practical discussion guide to building a .NET application in a service-oriented architecture. We will consider real-world goals, real-world obstacles, and experience-based solutions. I quickly concede the approaches discussed here are not exhaustive or infallible. This paper is focused on application development, not application integration. We will specifically consider architectural issues and component design issues.

The Potential of Web Services

Web Service for uploading documents into SharePoint

WS UploadService is a web service written for Microsoft Office SharePoint Server 2007 and Windows SharePoint Services 3.0 and is meant for uploading documents into SharePoint. I have just uploaded the zip file to GotDotNet.com so it will take some time before the zip file appears in the list of downloads. For the time being, you can download the zip file from the following location

Creating and Using an ASP.NET Web Service in Visual Web Developer

In addition to letting you create Web pages, Microsoft Visual Studio also lets you create Web services that use ASP.NET XML. Creating a Web service in Visual Studio is similar to creating a Web page. You can also use the Microsoft Visual Web Developer Web development tool to reference and use Web services that are in a Visual Web Developer solution, on your local computer or in a local or external UDDI directory. In this walkthrough, you will create the Web service in one solution and use it in another.

Tasks illustrated in this walkthrough include:

Creating a simple XML Web service in Visual Web Developer.

Creating a separate Web site that uses the Web service.

form feild hints are not displaying for textboxses inside create user wizard?



I'm using following JS code to display input hint box besides the textbox whenever that asp.net textbox receives focus. 

I'm doing this for a registration form and all of the textboxes are inside the asp.net create user wizard control.

<script type="text/javascript">
function addLoadEvent(func) {
  var oldonload = window.onload;
  if (typeof window.onload != 'function') {
    window.onload = func;
  } else {
    window.onload = function() {

function prepareInputsForHints() {
	var inputs = document.getElementsByTagName("TextBox");
	for (var i=0; i<inputs.length; i++){
		// test to see if the hint span exists first
		if (inputs[i].parentNode.getElementsByTagName("span")[0]) {
			// the span exists!  on focus, show the hint
			inputs[i].onfocus = function () {
				this.parentNode.getElementsByTagName("span")[0].style.display = "inline";
			// when the cursor moves away from the field, hide the hint
			inputs[i].onblur = function () {
				this.parentNode.getElementsByTagName("span")[0].style.display = "none";

AutoGenerateSelectButton="False" ignored when using Domain Service


Crosspost from RIA Services forum: http://forums.silverlight.net/forums/t/196466.aspx

I'm creating a Dynamic Data application in VS2010 and have recently switched to using a Domain Service to give greater control over the data presented to the client. I've noticed that the AutoGenerate<Action>Button attributes on my GridView are being ignored. The presence of the Edit and Delete buttons appear to be contingent on the existence of Update and Delete methods on the partial classes autogenerated in the Domain Service, but i'm not seeing how to control the generation of the Select button. Is there a way to control this from within the Domain Service class?

Any framework for creating a job scheduler service?


Just curious to know if there was any official Microsoft code blocks, classes, or such for writing a service that runs other assemblies or WCF services?  That can be configured easily from a web page, pre-coded, for running tasks at certain times on certain recurring intervals?  I've already built one but am open to anything done better- which I'm sure there is.  Thanks!!!
