You can take Pass the combobox item to your database.

use : custnam.SelectedItem.toString()

and for account name : accname.SelectedItem.toString()

if still not able to understand. paste your code so we can understand your problem.

for Customer Name use

custname.SelectedValue.ToString();

and for Account Name use

accname.SelectedValue.ToString();

SelectedValue property will give you the currently selected value from the ComboBox control. This will work in WinForms.

For WebForms

use SelectedItem property in place of SelectedValue.

Bhavik_Patel · Answer 3 · 2014-07-17T18:43:00

you can use SelectedItem.Text or SelectedItem.ToString()
example

C#

ddlcustname.SelectedItem.Text or ddlcustname.SelectedItem.ToString()

and

C#

ddlaccname.SelectedItem.Text or ddlaccname.SelectedItem.ToString()

One Suggestion
If your custname and accname are editable then you should take CustId and AccId in PaymentTable for data accuracy

Ignore if it's applicable in your case
