Hi,

Is it possible to use Field Names with Data Row.

for example:

Dim dr As DataRow = CType(Me.ProductsBindingSource.Current, DataRow)
dr.ProductID=123
dr.ProductName="ABC"
Me.ProductsBindingSource.EndEdit()
Me.ProductsTableAdapter.Update(Me.Inventory_Control1DataSet.Products)

Best Regards,

Yes, like this:
Dim dr As DataRow = CType(Me.ProductsBindingSource.Current, DataRow)
dr.Item("ProductID") = 123
dr.Item("ProductName") = "ABC"

Hi,

following line giving error.

Dim dr As DataRow = CType(Me.ProductsBindingSource.Current, DataRow)

System.InvalidCastException was unhandled
Message="Unable to cast object of type 'System.Data.DataRowView' to type 'System.Data.DataRow'."


Any idea please ?



Best Regards,

Luqman
 
Luqman,
BindingSource.Current returns a DataRowView instead of a DataRow, change
your cast to be:

Dim dr As DataRowView = CType(Me.ProductsBindingSource.Current,
DataRowView)

DataRowView & DataRow as analogous to DataView & DataTable.

If you want the actual DataRow, you can use the DataRowView.Row property:

Dim dr As DataRow = CType(Me.ProductsBindingSource.Current,
DataRowView).Row
