How to insert combobox into WinForm

[Kamal Ahmed]

Hi, All

I have a datagrid binded to a datasource. I want to display a lookup field
in the same grid using combo box. I also want to display a calculated field
in datagrid i.e.
Qty x Rate (Amount). How is it possible.

TIA

hi Kamal
for the calculated field, in your code for the dataset, you should go to the
DataColumn.Expression property for one of the columns in your datatable. or
you can create a new column, and set the Expression to something like Qty *
Rate.
for more info on this property, see SDK docs:
ms-help://MS.NETFrameworkSDKv1.1/cpref/html/frlrfSystemDataDataColumnClassExpressionTopic.htm

there are several solutions to changing/replacing a standard text box to a
combo box for a column in the datagrid. some of them are quite crude, and i
have never found one that didn't cause other problems. this should get you
started:
