I've hooked up a TextBox's Text property with the property of a class.
However, when invalid data is entered, the data binding updates the object
immediately. Is there anyway to prevent this from happening? Or should I
just re-assign the value to the object directly in this case?
Thanks,
Michael

Hi,
I have an object that I am binding to a text box, this object exposes a
boolean field, and I have implemented a format event handler and a
parse event handler for the binding object, where I convert the bool
value to some meaningful text.
i.e.

I have a ComboBox and a TextBox bound to a Dataset/datatable returned from a
SQL Database. The databinding is set in Design Mode.
Everything works fine on my initial fill, and I get the correct list of
items in the combobox, and the textbox which is bound to a second column in
the same table, changes to the appropriate value when a new item is selected
in the ComboBox. The ComboBox is displaying a list of products, and the
texbox the...

Hi all,
I may be missing something with how databinding works but I have bound a
datasource to a control and everything is great, the control updates to
reflect the state of my datasource when I update the datasource - awesome,
but I have an issue with updating from a different thread.
Here is my datasource, a person class that raises the PropertyChanged event:
class Person : INotifyPropertyChanged

Hello is there a way to implement 2-way databinding without using the
datasources from dotnet 2.0. Why would you ask? Now that's simple.
I've created an object model with BusinessObjects and I don't want to write
an separate provider layer for the datasources. This is because I loose all
the benefits of my objectmodel.
Are there other developers who think this way?

I am confused about the way in which asp:table objects work. When a control
is within an asp table it generally appears to be in the scope of the tables
parent control. E.g. if i have a page that consists of an asp table called
MyTable containing a textbox control call MyTextBox then i can access
MyTextBox directly from the PageLoad event handler without having to use
MyTable.FindControl(MyTextBox). MyTextBox can also be used for a...

Hi,
Does the databinding support in ASP.NET 2.0 support two way databinding to
datasets?
I have a dataset, which is populated with data. I just want to bind the UI
to it. I'm struggling to see any way to do this, and I see this post, which
seems to suggest that it cannot be done (unless you write an additional
adapter class):...

Hi,
I've got a question which I'm hoping has a simple answer.
I have a series of control bound to an underlying DataTable.
The databinding are setup to update the data source on validation.
I have an event handler monitoring the ColumnChanged event on the DataTable, and in certain circumstances I update another column in the datatable.

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
