I am using Visual Studio Professional 2012, and I am working on a Windows Forms Application. While working with the datagrid view, the selectedIndexChanged Event is not available in the list of available events. How can I implement this event?

There is actually no such event in a DataGridView. You can search the msdn help. Use SelectionChanged event instead.

I'm new to C# and delegates, however, from what I've gathered, they say if this event happened run this method. But in Visual Studio (community 2017), I can't figure out where/how I am meant to go about defining/attaching them.
I'd appreciate an answer as I'm trying to go about switching a program I've previously written in Python over to C#.
I've looked through documentation, I've looked over questions already asked here, and none of them seem to give me the information I'm after.
To add delegates (in this case they're typically called "event handlers") to UI controls in WinForms, you should:
Select the control in the visual designer
Look at the Properties windows
Click the lightning bolt to view the events.
Either double-click the blank space next to an event to auto-generate a handler, or single-click and select an existing handler from the dropdown.
Installed products

Description
Visual Studio extension that contains a toolbar with drop down combo still receives advised selection(IVsSelectionEvents) events after toolbar is hidden.
Steps to recreate
Use Drop Down Combo from https://github.com/Microsoft/VSSDK-Extensibility-Samples/tree/master/Combo_Box sample
Use IVsMonitorSelection.AdviseSelectionEvents()
Hide the toolbar.
Current behavior
I could not find any event to be notified when toolbar is hidden/shown so could not stop receiving IVsSelectionEvents interfaces OnSelectionChanged event.
Expected behavior
Notified when toolbar is hidden or shown so Advise/UnadviseSelectionEvents() could be called.
So, i need an event that is triggered when toolbar is shown and hidden.
I Have Winforms and crate drag drop for my tree view using Drag Drop Sample in code project.
this worked before I upgrade my project to VS 2013 update 3 but when project upgrade to VS 2013 I can not start drag in tree view.
I so confused for this complicated problem
Please help me.
Please check this steps:
You must first set AllowDrop=true;
Set Event ItemDrag
Set Event DragDrop
Set Event DragEnter
Set Event DragOver
If your tree drag drop worked before and now not work I think it must be for your data structure that checked in DragDrop Event or some other event of drag drop
I am using WebKit browser control in my .net winform application. However, I noticed that its DragEnter, DragOver, DragDrop events are not firing. I am trying to drop a tree view node into it.
Please help.
Thanks,

after I did this application using visual C# ... Simply nothing on the form is working its like disconnected any ideas why ?
Check if the event handlers for the Button.Click events are set. Visual Studio tends to drop the event handlers some times.
Open up your form in design mode and check if the click event is set for your buttons by inspecting them in the property grid. If they aren't then you can reselect the method using the drop-down menu.
