Changes to datagrid aren't made to dataset.

Using C# and winforms.datagrid control

I have a datagrid that is bound to a dataset and the binding is done
like this:


connection1_admin.Open();


SqlCommand myCommand1 = new SqlCommand("select OrgSystemID, OrgSystem,
OrgSystemDescr from tblOrgsystem",connection1_admin);
adapter1_admin=new SqlDataAdapter();
adapter1_admin.SelectCommand = myCommand1;
ds1_admin = new DataSet("tblOrgsystem");
adapter1_admin.Fill(ds1_admin, "tblOrgsystem");
dg1_admin.SetDataBinding(ds1_admin, "tblOrgsystem");
SizeDataGridColumnsToContent(dg1_admin, -1);


connection1_admin.Closed();


When the user makes changes to the datagrid, shouldn't the dataset
reflect these changes?


frmEditOrgSystem frmEditOrgSystem = new frmEditOrgSystem();
DataGridCell currCell;
currCell = dg1_admin.CurrentCell;
int RowNumber = dg1_admin.CurrentRowIndex;
dg1_admin[RowNumber,1] = str_editsystem1;
dg1_admin[RowNumber,2] = str_editsystem2;


However when I do ds1_admin.HasChanges() I get nothing until.....
I click on a different row of the datagrid, then it finds the changes.


Does anyone have any idea what I'm doing wrong????

Hello rhaazy,

Whenever you change focus from a cell to another or from a row to another,
you better accept the changes from the datagridview to dataset or datatable.
e.g.
ds1_admin.AcceptChanges();

This would save the data in the dataset and later on you can manipulate with
the changed data.

I have tried this and it does not work. The dataset does not receive
the changes made to the datagrid until I change from one cell or row to
another... I have tried everything, from beginedit()...endedit(),
acceptchanges() update() refresh(), nothing, i can't figure it out...
