How to capture ReportViewer Mouse Events


I have a ReportViewer which I'm pulling into a C# WPF project, and would like to be able to capture the row a user clicks on in the reportViewer, but have had no success tapping into the mouse event handlers.   Does anyone know how to accomplish this?  

This MSDN link seems to imply that ReportViewer(winforms) supports mouse click events such as Click, DoubleClick..etc.  http://msdn.microsoft.com/en-us/library/microsoft.reporting.winforms.reportviewer_events.aspx, but I've not had any luck.

If mouse events are not currently supported, does anyone know when they will be, and whether properties such as SelectedItem or SelectedIndex would also be exposed?

Thanks for the help.

How to insert a name field on an InfoPath path that allows you to insert names from the AD directory

How can I set up a field on an Infopath form so that when I click on a "Check Names" button, (exactly the same way it works on a SharePoint point Name field), the name is checked against the AD directory? I am not trying to control user access to sections of the form - I am simply adding names to the form that is collecting data on a task - such as Delivery Lead, Designer, etc.

Rotating Graphical path with mouse move



So, I have written a code to draw a graphical replica of human Hand with 'DrawPath' Class. The static graphic looks good, but I want to use it with mouse move so It can act like a human hand with the movement of cursor. The problem I am facing is that when I move my object with mouse move [as I have Hard coded the hand with its first finger basically representing the Mouse position and then drawing other points from it], the hand seem to loose its shape.


The problem occurs because when hand moves the orientation changes and the hard coded code just brings the points closer to each other or if I don't do that then orientation doesn't change [hand remains same as exactly upright]. Do anyone know which factor I should add with each points of my hand so it preserve it shape or better if there is any function which can control orientation automatically??


All help is much appreciated

Export Visio Database Table Names to Excel

If you use the Enterprise Architect edition of Microsoft Visio for data modeling regularly, then there is a good chance that at some point you've wanted to export just the table names into Excel. You might want to do this to map logical ERD entities to physical data model tables, track project status by entity, or track overlap between database versions.

WCF Tutorial - Events and Callbacks

we described how to make a very simple client/server application where clients would call functions on the server through a shared interface. In this tutorial, I'm going to expand that application to allow the server to execute functions on the client by using callbacks. Essentially, this is WCF's mechanism to allow events to be raised from the server to it's connected clients.

How to highlight datagrid or GridView row on mouse over?

This article will show how you can Ajax with GridView to display popup messages when mouse moves over certain column. In the demo project I have added first column as an image column with a help icon in it. This kind of implements a feature that if you want more information about the row you can move mouse over this icon, a asynchronous request is sent to server for data about that row and when call returns the returned message is show as a popup message.

Delegates and events in c#.net

People often find it difficult to see the difference between events and delegates. C# doesn't help matters by allowing you to declare field-like events which are automatically backed by a delegate variable of the same name. This article aims to clarify the matter for you. Another source of confusion is the overloading of the term "delegate". Sometimes it is used to mean a delegate type, and at other times it can be used to mean an instance of a delegate type. I'll use "delegate type" and "delegate instance" to distinguish between them, and "delegate" when talking about the whole topic in a general sense.

Retrieving a variable from a previous page



I'm looking to have a search page where a user will select an item from a listview, then then taken to another page that wil display data based on their original selection.

A user will type in a string and be presented with a list of usernames that are like that string, when they select a user name who's profile they would like to view I would like the page that they're taken to, to be that users profile.

How would I transfer the variable from the search page to the profile page, and when I work on the profile page, how can I access that variable?

Tab container rendered with visibility:hidden - This was reported over three years ago.



Here is (more) code that demonstrates the issue.  If the control in the host page is removed the tab control renders correctly.  Otherwise it is rendered with the visibility attrubute set to hidden as reported in the above link.  Is this broken or am I doing something wrong?

Hidden variable has no value


I know I have a valid solution, but the js is telling me that the value in the hdnRecordSaved variable has no value!
Even when I specify in my function the following, it still tells me it has no value:
var myTextField = document.getElementById('hdnRecordSaved');

When I put the full value of the variable in (ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved.value), I get the correct contents back ("1"), which I set in my code behind. However, I would prefer to just put the short name in since the masterpages may change, etc. Unfortunately, I know I can get around this with VS2010, but we are using VS2008.

What am I doing wrong with the js naming conventions that can't give me the contents? Here is my below js.

<asp:Panel ID="pnlMapFields" runat="server" ScrollBars="Both" Height="430px">

<telerik:RadTreeView ID="RadTreeView1" runat="server" DataTextField="Description"

DataFieldParentID="MapFieldparentID" DataF

I want users to only type  applicationName on the web adress area.I believe there is something to do with alias and CNAME on DNS records that can adress this.

Any help on how to go about doing this will be highly appreciated.

How to set SearchRoot Path in Active Directory in this scenario


How to set SearchRoot Path in Active Directory in this scenario:

Functionality: We have scenario that 1<sup>st</sup> hit one LDAP server with some 'fixed user name' &' fixed password ' and filter data with specific User name(which given by user) getting 'User dn'.

dynamically change column names in Crystal reports


I need to develop 3 pages.

On the first page user defines atmost 7 column names to be displayed on the report. I'm saving these names in a Sql DB table 'Columns' with Column_Nm and Column_ID as Table columns.

On the second page I'm retrieving column_Nm from the table and displaying them on the page so that the user enters the data. This data is saved in another table 'Summary' with the Columns column1 through column7.

on the 3rd page I need to show a report of 'Summary' table.

How do I dynamically replace column1 through column7 names with that of 'Column_Nm' on the report?

Any help/suggestions would be appreciated.
