Hi,
I have an Access database in which I defined default values for certain
columns. On my windows forms I've got controls bound to the dataset, The
problem is that when I add a new row to the dataset my controls don't have
the defaultvalue entered in the database.
Is it possible to retrieve the defaultvalue for the column from the
database?

How can I set the DefaultValue property of DataColumn to false in C#
this.objdsMyDataSet.tblMyTable.MyBooleanColumn.DefaultValue = false;
I have also tried setting it to System.Data.SqlTypes.SqlBoolean.False;
but in either case I get ArgumentException.
What is wrong, it looks straightforward to me.

Hi I succeded to add a DataColumn to DataSet but now I've one big problem.
The value of this column would be a personal function result, I try a lot of
time but the result is always empty.
Why?
There's a method to do this thing?
This is the code
cols = ImageDataSet.Tables("Immagini").Columns
myCol = cols.Add()
With myCol

Hi!
What's the correct syntax for the default value design time attribute, using
classdiagram view and Custom Attributes dialog.
For a boolean:
DefaultValue(true)
DefaultValue("true")
DefaultValue("bool","true")

Hi All,
I am currently learning .Net 2, studying for 70-528. I've hit a bit of
a brick wall with DataColumn.Expression. As I understand it, this can
be used to (For example) concatenate two columns to make a derived
column.
When I run my code, I get this error:
