The user controls have no knowlegde of each other. The form in which the controls are contained, manages the interaction.

• Fahad Hanif How do I create an object from a row in a DataGridView / BindingSource?

  I would like to create an Object (say Client) from the currently selected row in a DataGridView. The DataGridView's DataSource is a BindingSource, for which the DataSource is a DataSet containing a single Table of Clients. I have been advised to use the BindingSource.Current property to get the selected item (or row), rather than the DataGridView. I have tried the following: DomainClient c_client = (DomainClient)c_bindingSource.Current; which results in an exception. How can I get around this Thanks in advance, JackStri.

• Gravy Open IE and Navigate from VB.Net

  Can anyone tell me how to open Internet Explorer and navigate to URLs from vb.net When the user clicks a button on my windows form I would like it to navigate to a URL in Internet Explorer. If there is already an IE window open, I would like it to reuse it. Something like this: If (IE is not open) then Open IE End If Navigate to URL Thanks System.Diagnostics.Process.Start("iexplore http://www.yoursite.com")   not quite I believe, unless you get a handle of the window then do some Win32 call like SendMessage or something. The reason is because you are killing the process, which means it gets rid of it completely.   I guess you could maybe do this, and see if it helps   if myProces ...Show All

• lucerias Error creating clickonce package with .NET 3.0

  I am having a problem publishing a clickonce package with the .NET 3.0 runtime as a prerequisite. I have installed the September CTP of ORCA's extensions for VS 2005, the associated Windows SDK and the associated .NET runtime.

• Bill Reiss Datagrid navigation

  Hi all, I have a datagrid in my aplication form that I fill in the fly by C# code. Basically, the datasource is an ArrayList. What I want to do is enable the user to not only edit the data in the grid (which is easy), but also change the order of the lines. The best solution will be to add 2 Up and Down arrow on the form to allow the user to do it. That will be the most friendly solution. Does anybody know how I can achieve this with C# Thanks in advance, Bertrand Thanks Bob, I already found this. So everything works as required. If anybody wants to see the code, just email me.
