This question pertains to C#...

Hello,
I have a C# dataSet  in a windows form which is bound to a SQL table ...

Can you assign columns of a the dataGrid control  default values so that these values will be persisted to the database table??

If you're binding to a Dataset, you'd set defaults like this:

If you just want to modify the DataGrid defaults, try doing it to the DataColumn in question:

If you want to alter the default on the SQL Server, you could use an ALTER TABLE ... column DEFAULT

dave,

Thanks for the links! I guess I am trying to set the DataColumn defaults of the dataGrid1 object below. It looks like from one of your links, I need to call the DefaultValue property on each DataColumn of datGrid1.

Hmm, I'm unsure how to do this. Do I need to create another mehod to iterate through each DataColumn somehow?

My codebelow:

string ConStr = LoginFirst.Connection;
string SQL = "SELECT Field1, Field2, Field3 FROM Table1 ";

   OleDbConnection Conn = new OleDbConnection(ConStr);                  
   oleDbCommand1 = new OleDbCommand(SQL, Conn);
   da = new OleDbDataAdapter();
   da.SelectCommand = oleDbCommand1;
   oleDbCb = new OleDbCommandBuilder(da);
   da.Fill(dataSet1, "POB");
   dataGrid1.SetDataBinding(dataSet1, "POB");
   
da.Update(dataSet1, "POB");
MessageBox.Show("Your changes have persisted to the Database!");
This one is on us!

OK - I cannot find where in the designer to configure defaults. Could you give me another hint? :-)

Thanks
