You need to use data bindings. Bind your CB DataSource to recordset and set the DisplayMember and ValueMember.

Read Data binding concepts in .NET windows forms[^] and Data binding in WPF[^]

Hi,

Add items to your combo box in the below way in your data read,

comboboxid.add.items(marital_status);

or get a dataset and bind it to your combo box.like,

C#

// Setup the combobox view and display-, value member
comboboxid.DataSource = dsView;
comboboxid.DisplayMember = "CompanyName";
comboboxid.ValueMember = "CustomerID";

Hope this helps.

Also, check this link for data binding examples.
