Good day

I have created a two forms in my Windows application. On my Main form is a combobox and on my second(child) form is a button.

I want to populate the combobox with a dictionary when the button is clicked on the child form.

I have written the dictionary that is calling a short procedure. The dictionary is working and is populating from the main form.

Here is the dictionary code on the Main Form

public void dctRplStatus()
                Dictionary<string, int> objdic = new Dictionary<string, int>();
                objdic = clsIngadmin.SelectdicReplacementStatus();
                cmbRplStatus.DisplayMember = "Key";
                cmbRplStatus.ValueMember = "Value";
                cmbRplStatus.DataSource = new BindingSource(objdic, null);
                objdic = null;

Code on child form on the button click event

frmMain formmain = new frmMain()
formmain.cmbRplStatus = dctRplStatus;

I get an error connot convert type 'void' to 'System.Windows.Forms.Combobox'

I change my dctRplStatus() method to a string and tried to return the objdic but it did not work.

What am I doing wrong?

Change the method signature of dctRplStatus to
public void dctRplStatus(ComboBox cmbRplStatus)
and replace
formmain.cmbRplStatus = dctRplStatus;
ensure that formmain.cmbRplStatus has public access.
