I have a combobox called sPropertyCountyCd whose datasource is a dataview.
The first time I set the filter to the dataview, attach the combobox to the
dataview, and set the selected index to -1 is comes up correctly as blank.
However, if I change the filter, and set the selected index to -1, is always
shows the first record from the dataview and changes the index to 0. I even
tried to set the datasource to null, and then reassigning the...

Hi,
I have a problem with a ComboBox bound to a DataView.
The ComboBox shows the correct number of rows but instead of the data, each
row shows "System.Data.DataRowView"
Can someone explain how to fix this and why it is happening?
The Form's Class has:

I have 2 bound ComboBoxes. I want the datasource of the second to be limited
by the selection made in the first. I can do this by responding to the
SelectionIndexChanged event on the first, but this results in the
BindingContext's Current.Row.Rowstate becoming 'Modified' whenever the
BindingContext position changes. What is the RIGHT way to go about this?
Thanks,

Hi-
I've seen this problem discussed a jillion times but I cannot seem to
implement any advice that makes it work. I am porting a large project from
VB6 to .NET. The issue is using the combo box bound to a table as a lookup,
drawing values from another table to populate the available selections. This
all worked fine in VB6.
I have distilled the problem down to a simple form drawing data from the
Northwind database for a representative...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
