I need to have a column that should display a combobox. However the contents of the combobox are not always the same, they depend on the value of another cell. So I want is that when the cellEnter event of the column in question fires, the combobox appears on the current cell and its contents depend on the cell to the left. When the cellLeave event of the same column fires, the combobox disappears and the cell now is just a text cell with the contents of the selected item from the combobox. When the cellEnter event in the Column in question fires and the cell is not empty, the combobox should appear and the text selected from the items list
Thanking You

There are lots of great samples of how to manipulate the DataGrid here:
http://www.syncfusion.com/FAQ/winforms/default.aspx#44[^]
But look real closely at example 5.9. In there it talks about creating the combobox and filling it with data. Do you want the data in the combobox to be bound or unbound?

It's waiting for information which is why your program hangs. You need to set the ReadTimeout. When it times out readline throws an error so be sure to wrap that statement in a try catch block.

Hi Guys
I was wondering if someone could help me figure out what I need to do to get this function to perform properly
Let me explain what I am doing.
I have an updating app to update a different app.
Since it is critical for internet connection to be valid I made a function to do the check. And not like microsoft and other boards suggest because that really only tells you you have a connection but not that you can actually communicate. For example I could change my IP address on my nic and not be able to browse yet it still says I'm connected.
So my function startecd off as a simple My.computer.network.ping
That was working great until I realized when I was at my friends house that some isp's block the ICMP request even though the connection is valid.
So I said ok I am going to change the ping to a lookup routine for a domain and if its address length=3 which means it found it then internet is available.
Now that works great in both situations where icmp is available or not except the delay in the check is slower than a straight ping request.
So what I was trying to do next was to first try the ping and if it didnt work try the nslookup and then return a value. It seems to be working but it seems to hang my machine.
I think I'm looped wrong or something. For example I have an animated gif on my main form that when it runs the function in dual mode moves at a snails pace. When I use either ping or nslookup alone it functions fine.
Do I need a background worker or something.
I'm sorry I am very new to programming and don't really even understand how to use background workers or if thats what I even need.
Maybe I just need to reorder my function.
In either case I will post my function code. If this info isn't sufficient I will add anything you need.
Thank you in advance
Tony
Private Function isConnected() As String
Try
If Not My.Computer.Network.Ping("www.google.com") Then GoTo TryNext
TryNext:
Dim AddressLength As IPHostEntry
AddressLength = System.Net.Dns.GetHostEntry("google.com")
If AddressLength.AddressList.Length.Equals(3) Then
'The above three lines works better then this in case icmp is unavailable
'If My.Computer.Network.Ping("www.google.com") Then
m_isNetConnected = "Available"
Return m_isNetConnected
Else
m_isNetConnected = "Unavailable"
Return m_isNetConnected
End If
Catch Except As System.Net.Sockets.SocketException
m_isNetConnected = "Unavailable"
Return m_isNetConnected
Catch Except As InvalidOperationException
m_isNetConnected = "Unavailable"
Return m_isNetConnected
End Try
End Function

Im sorry I forgot to add that this function is rechecked repeatedly by a timer so that it shows u if you are connected in realtime.
Thanks again

Well I think your function could be cleaned up a little bit. First of all it seems to me it should return a boolean value instead of a string. Secondly this next line of yours is pretty useless:
tgebrael wrote: If Not My.Computer.Network.Ping("www.google.com") Then GoTo TryNext
All this does is test if the ping succeeds and if it doesn't it skips to the next line. Skipping to the next line is unnecessary as your code would do that anyway without the goto statment. Also if it succeeds it again moves onto the next line and will execute the second method. So no matter what your function is trying both methods. This is one reason why you might find it slow. Instead of goto TryNext how about you just return "Available" or True if you decide to change it.
Also in every exception you have the same code. How about you move that code below the try catch block. It's just redundent. How about this:
Private Function isConnected() As Boolean
Try
'If ping succeed return
If My.Computer.Network.Ping("www.google.com") Then Return True
Dim AddressLength As IPHostEntry
AddressLength = System.Net.Dns.GetHostEntry("google.com")
'If lookup succeed return
If AddressLength.AddressList.Length.Equals(3) Then Return True
Catch Except As System.Net.Sockets.SocketException
'Catch exception
Catch Except As InvalidOperationException
'Catch exception
End Try
'If we got this far attempts failed. Return false
Return False
End Function
If you still want to return a string you could modify it back to how you had it.
Also if you'd like to use the backgroundworker try it out. It's pretty easy to use. I'm sure you can find info online about it. It has a DoWork event which fires when you call the method 'RunWorkerAsync'. The code in this event runs asyncronosly. So all you'd have to do is in the DoWork event call your function get the value and then pass it back to the main thread. There is a RunWorkerCompleted event which fires when the task is completed. You can pass the result on to it and then do whatever you want with the value.
