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.

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.

SendInput fails to control mouse in x64

I am currently working on a project in which I'm trying to make a program which can input mouse movements to click and drag objects. I've imported user32.dll and created my inputs exactly as the help info and pinvoke.net instruct so as to be able to send mouse inputs. Nevertheless, whenever I implement the SendInput function, it always returns that it successfully inserted 0 events into the keyboard and mouse input stream and when I run GetLastError, it gives me error 1400 INVALID_WINDOW_HANDLE. I've tried the same code on two different systems, both running in x64. One is XP and the other is Windows 7. Neither works. If you're interested in the code, it's basically a 64-bit version of Johnny Chung Lee's Wiimote Whiteboard program. I've made a few modifications, but the main gruntwork of the program is the same as his original. His stuff can be found here: http://johnnylee.net/projects/wii/

SQL Server Management Studio Slow Grid Draw and Refresh

I've istalled SQL2005/SSMS on my development machine and connecting to a local SQL Server 2005. Executing queries is fast but the results grid populating is slow and so is the refresh of the same data. This is not a slow query, its the gridview draw/redraw. I've other PC's with slower processors and less ram with the same software run circles around the SMSS Performance on this Laptop   I've read posts about nvidia graphics drivers and mouse drivers causing issues similar to this. I do have an nvidia quadro x1600M (this is a laptop Compaq 8710w) and switching off the accelerator using Displays/Advanced/Troubleshooting by moving the slider to the middle/center position causes the gird refresh to dramatically increase. It's funny how turning oof the accelerator increases performance.   I have the latest HP nvidia drivers and SSMS is useable without hardware acceleration  but I also develop software that uses directx and its getting really troublesome to work this way.   I am running:   Operating System: Windows XP Professional (5.1, Build 2600) Service Pack 2 (2600.xpsp_sp2_qfe.070227-2300)Language: English (Regional Setting: English)System Manufacturer: Hewlett-PackardSystem Model: HP Compaq 8710wBIOS: EPP runtime BIOS - Version 1.1 Processor: Intel(R) Core(TM)2 Duo CPU     T7300  @ 2.00GHz (2 CPUs)Memory: 3072MB RAMPage File: 515MB used, 4439MB availableWindows Dir: C:\WIN

In other words how do I move over a scrollbar while the mouse button is down, and then the scrollbar gets the focus and begin to scroll to the mouse pos. Please help me. Spandy   

A layout, mouse selection, ListView problem/question

I'm having a problem with a particular layout scenario, and how it interacts with a left mouse click in certain situations. I have 3 rows in a Grid.  The first is a ListView (Master), with the Row Height set to '*'. It's ItemSource is bound to a collection in a ViewModel, and its SelectedItem is bound to a value in the ViewModel.  When the SelectedItem is null, it should take up its entire container (the other 2 rows are invisible). The second row is the GridSplitter.  It's visibility is bound to a value in the ViewModel.  It's only visible when the SelectedItem in the Master ListView is not null.  It's GridRow height is set to Auto, and it's height is explicitly set to 5 (via a style). The third row is a sub-ListView that shows Detail data for the Master SelectedItem in the top ListView.  It's GridRow Height is set to zero by default, and if an item is selected in the Master ListView, it should become visible and have a set height (400 to start, via a binding on the Height of the row). The desired effect is that when an item is selected in the Master ListView, the Detail ListView becomes visible and the GridSplitter allows you to resize the top and bottom as needed.  If necessary, the ScrollBars become visible in the Master ListView to show any items that are now obscured by the Detail ListView (via the automatic scrolling featur
