Hi Steve,
I see that you are working with two grids, one for the parent data and one for the children. I just used one grid to display them both. A thing which the UltraGrid does quite well.
I just dug out my old project, where I used the Infragistics grid (Version 3).
The code that works (.NET 1.1) creates a New DataSet in which two DataTables are created and filled via DataAdapter.Fill and following DataSet.Tables.Add(). The DataRelation is added just like in your code and the DataSet is bound to the grid's DataSource property. All other properties of the grid with their default values.
In the code you posted it seems that you are setting UltraGrid1's datasource twice:
Me.UltraGrid1.DataMember = "Assembly"<br />
Me.UltraGrid1.DataSource = Me.DsCustomerEquipment1
and
Me.UltraGrid1.SetDataBinding(Me.DsCustomerEquipment1, "Assembly")
Could this be the problem? Otherwise I don't have any more ideas

Hello Andi,
Thanks for your reply and patience.
I am only using 1 ultragrid to display the parent and children relationship.
I have set the relationship in the designer and tested to see if it would display the parents and children and it did. I also tested this doing it the code way. Also worked.
I wasn't setting the datasource twice, i tried both methods individually to see if they would work.
However, the problem is that I only want to display the parents and children that belong to a certain customer, rather they displaying all of them.
Thats the real problem, and still can't find the answer.
I think there could be a problem with the sql query or the way i am filling the dataset.
If you have any more ideas on this, please let me know. I just want to solve this problem before i pull my hair out.
Many thanks,
Steve

Hi Steve,
you'd better let your hair be. For me it often worked to just let it settle for a while and have a beer/whisky/milk or whatever you prefer 
If the grid works as desired but does show all the assemblies of all customers, then there must be something wrong with the way you fill your dataset. At least the parent table must contain only the desired records. It doesn't matter if there are too many child records (except for the unnecessary overhead).
Things I'd have a look at in the debugger:
- do you get the correct CustomerID?
- does the query which fetches the assembly records only return those for that particular customer?
Sorry that I can't be of more help, but I'm running out of ideas as well.

Hi,
I'm working on a system to read in xml files( the xml files are generated from a from.designer.vb file)and create form of it. I'm looking for a way to dynamicaly create a button or a textbox so I tryed this:
Dim o As New Object<br />
o = Activator.CreateInstance(System.Type.GetType("System.Windows.Forms.Button"))
But the code above fails to work i'm always getting the same null 
And my second problem is I need to set the properties of an object dynamicaly this means:
Form.controls.Item("naamofobject").text = "" <-- this is the way i know but i'm looking for a way like this:
Form.controls.Item("naamofobject").("propertynama") = "" <-- could this be possible in any way?
Thx in advance

Dim oBtn as new system.windows.forms.button
oBtn.Name = "cmd"
oBtn.Text = "Press Me"
me.controls.add(obtn)
obtn.left = 100
obtn.top = 100
Dim oTxt as new system.windows.forms.textbox
oTxt.Name = "txt"
oTxt.Text = String.Empty
me.controls.add(oTxt)
oTxt.left = oBtn.Left + oBtn.width + 10
oTxt.top = 100

That i know but in xml files there can be 50 form controls and then i can't type it :p

Your original message said "I'm looking for a way to dynamicaly create a button or a textbox" what i gave you dynamically creates it. now using that technique apply it to your xml. if your still struggling...give a little sample of your xml content so I can help you apply the technique I gave you to it...

Hi all,
I have a datagridview (whose datasource is an untyped dataset) and a textbox in a form .
My grid(and dataset) has three columns.
My requirement is as the user keys in letters in the textbox the closest match should be highlighted in the grid and I must be getting autoselect options in the textbox.
For eg.Suppose I have words MICHIGAN and MICHAEL in the dataset
I key in M in the textbox ,then my textbox should have MICHAEL in it with "ICHEAL" highlighted.
The search is to be performed in only one column of the dataset.
Any help in this regards prefarably code snippets(vb.net,windows application) or approach is highly solicited

I have a scenario in which I have aform that contains a datagridview, 2-3 labels and text boxes ,1-2 buttons on the form.
This form opens as a pop up when click a button in the parent form.Now I want to close this form when the user click any where in the parent form.
I have tried using lostfocus event of the particular form .
Please send me suitable code snippets if possible or the approach to go about it.
Looking forward to a quick reply

Sandy, close it in the activate event of the parent form.
Private Sub Form1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated
If Not IsNothing(moPopup) Then
moPopup.Close()
moPopup = Nothing
End if
End Sub

Why I only can deploy 1 time? When I deploy second time, error will come out.
Error 1 Deployment and/or registration failed with error: 0x8973190e. Error writing file '%CSIDL_PROGRAM_FILES%\teh\teh.exe'. Error 0x80070020: The process cannot access the file because it is being used by another process.
Device Connectivity Component
Another problem is the file in PDA also can run 1 time only, after i closed my application, i want to run it again and tap the exe file, but no response at all. Why like that??
Both of this problem can solve by reset my PDA. It is troublesome. Is it normal?

Because the second time, you're trying to write to a file that's been installed, and is running. Why would you deploy without removing it first ?

The same way you would anywhere else. With a SqlConnection.

Yes. You still connect with a SqlConnection object. Use the machine name, or IP address in the connection string instead of "(local)"

Yes.

Hi,
I need to rotate the 'A' button control by angle degrees at runtime. On click another 'B' button 'A' button should be rotated clockwise.
Is there any way to do this?
Rams
Be simple and Be sample.

No
You can pretend to rotate by 90% increments, that's about it, unless you use WPF, or do some funky owner drawing to fake it.
