Hello,
I have a complex problem, could you please help me.
The problem:
I have a form with a TabControl
. There are two TabPages
in the first is a dataGridView
and in the second are multiple comboboxes
.
DataGridView
is filled with data from Table1
, on the other tab the first combobox
datasource is set to TableCB1
, the second combobox
to TableCB2
etc.
Between TableCB1, TableCB2
... are DataRelations
like (TableCB1.ID->TableCB2.ParentID
). I'm using databindings to bind current columns from table to controls.
When I open the form, first tabPage (dataGridView
) is filled and works ok, but if I select the second TabPage (with comboboxes
) then the combobox
selected items are not correct selected!!! Only the first combobox
is set correctly but all other have selected the first item in datasource until I change the bindingsource position or make dataset.rejectchanges()
.
But if make TabPage two to be shown on form load, then the combobox items are selected correctly!
I know it's a very specific problem but, hope somebody could help me to solve this problem.
I'm doing it on .NET3.5 and winforms.
Thanks.
