Data Grid / Data Grid View.

Hi all,

I am developing an Inventory system for my project,

I need to know the steps need to display data in a Datagrid view or DataGrid, when I select a particila Item.

Requirement,

User should be given a comboBox to select the Item no. Once selected the respective Item Details should appear from Item file.

Then the user should enter the Quantity.

Once the quantity is enterd the entire data should be saved in the OrderLine File.

=============================================================

As mentioned above my problam is, binding the DataGridView  to two members, i.e. ItemFile and OrderLineFile.

I need to read and diplay items from Item file onto the DataGrid and save it to the  OrderLineFile with the Quantity, from the DataGrid.

Please help me with this,

Thankx a Million
