Datagrid ( add row manually ) problem

[Agnes]

I got a Master-Detail relationship. Branch with dept (two tables) , as the
user input the Dept code, press 'Confirm' button,
I will select * from branch and input into the datatable mannually. the
dgBranchDept.datasource = myDataset. datamember= foreginconstraint_deptid.
I found the datatable got the data, but the datagrid display nothing. I
check the post before and try all the method. but still fail . please help

Here the following is my coding :---

drBranch = cmdBranch.ExecuteReader
dtSysBranchDept.BeginInit()
dgBranchDept.EndInit()
bmSysBranchDept.EndCurrentEdit()
Do While drBranch.Read
myDataRow = dtSysBranchDept.NewRow()
myDataRow.BeginEdit()
myDataRow.Item("branchid") = drBranch.Item("branchid")
myDataRow.item("deptid") = txtDeptId.Text
'MessageBox.Show(drBranch.Item("branchid")) <--- work fine
dtSysBranchDept.Rows.Add(myDataRow)
myDataRow.EndEdit()
Loop

drBranch.Close()
dtSysBranchDept.AcceptChanges()
Me.bmSysBranchDept.EndCurrentEdit()
dtSysBranchDept.EndInit()

Agnes,

As far as I can see is this code you are is exactly the same as what does
the dataadapter.fill with except setting the constraints, and the properties
of the datatable.

However why are you showing it, in my opinion is only importent that the
databinding for this to the datagrid is probably

\\\
dgBranchDept.datasource = dtSysBranchDept
///

A lot of work, to do it this way, I am curious what is the reason for that?
