Are you populating the WinForms ComboBox using binding to a Data source, so there is a DataMember, and ValueMember property; or, are you manually adding the Items ?

combobox binding code

cProduct obj = new cProduct();
obj.ppro_CompanyId = csession.CompanyId;
obj.ppro_IsActive = "true";
cmbProduct.DisplayMember = "ppro_ProductName";
cmbProduct.ValueMember ="ppro_ProductId";
cmbProduct.DataSource = obj.GetProduct();//returns Array list

It probably would have been better to ask "Could someone please show me how to do this in Windows Forms?" rather than what you asked; otherwise (in English at least) you can come across as demanding and rude.

Just saying... :-)

Anyway, this should work:

C#

ddScreanNameClass.SelectedItem = "3";

Sorry

No worries, it's ok if it's a genuine language mistake.
Anyway, did my solution work?

I think you are not observed the right hand side on the assignment operator
the digit "3" is the value field of one item in the combo box Need to select that item proramaticaly
