Hello All:
What I am trying to do is bind a textbox (really several
text boxes) based on a list box selection. Basically what
I'm dealing with are two tables with a 1 to 1
relationship.
I have created the dataset and defined the relationship
between the two tables in the schema. I add a list box to
a form and set it's datasource to the parent table and its
displaymember to the value I want to display from the
parent table, in my case:
DataSource = dsData.WNTable
DisplayMember = WN
Where
a.) "dsData" is the name of the dataset
b.) "WN" is the name of a field in the WNTable
Because the relationship is 1 to 1 I don't need to use a
datagrid (I can get this to work with a datagrid but this
is not ideal b/c it only returns 1 row). I only need a
text box for each value I want to display, so in my case I
want to add 3 text boxes that are bound by the
parent/child relationship so when I select an item from
the list the relevant data appears in the text boxes. I
tried setting the Text property of each text box by using
the defined relationship, for example one of the text
boxes Text property is:
dsData - WNTable.WN_Act. DFS
where
a.) "dsData" is the datset
b.) "WN_Act" is the relationship name that defines the
relationship between the WNTable and the ActTable
c.) "DFS" is a field in the ActTable, this is the value I
want to display in the text box.
When I run the program the list box and the text boxes are
not "related" at all. Is there a way to do this or do I
have to use a datagrid even though it would only contain 1
row of information? I set all of the properties,
relationships, etc. at design time (not with code). I
don't think this should matter but maybe it does. Please
Help!!
Many Thanks in Advance,
Jeff

Thank's for the pointer. I figured out what was wrong, I was setting
the data source incorrectly for the list box so there were two different
currency managers. Thanks for you help.

I'm thinking of implementing a real-time collaborative text editor in Python
using Twisted. An initial plan is to use a Twisted PB server daemon that
accepts user:password:file connections from text editor clients to make
changes to a specified file on the server, and have the text editor clients
update their local copies of the file based on local user input or input
entered from other users, relayed via the server.

I have a listbox with datasource from a dataview. When a user selects a
different item in a combobox then I need to refresh the listbox to the
appropriate listing based on that combobox's selected value which is included
in the listbox's filtering statement.
Is the only way to do this is to dispose the dataview and then create a new
one and then bind it to the listbox? Is there a better way than this?
Thanks, Alpha

the validator always returns false on isvalid and so does the

For most users, this new feature is actually very convenient. If you want to control the update process,...
