Solution 1

Change the combobox modifier to public and the you should be able to access it like this: formvalue.combobox1.SelectedValue.

Well the issue is its throwing the error as A field initializer cannot reference the non-static field, method, or property 'experiments.Form1.cbLoginCompany'

Please use:
<pre lang="cs">
experiments.Form1 formvalue=new experiments.Form1();
string cbValue = formvalue.cbLoginCompany.SelectedValue.ToString();
</pre>

Solution 2

Please use:

C#

experiments.Form1 formvalue=new experiments.Form1();
string cbValue = string.Empty;
if(formvalue.cbLoginCompany.SelectedValue != null)
{
   cbValue = formvalue.cbLoginCompany.SelectedValue.ToString();
}

I did the same long back, its throwing error at "SelectedValue". The issue is its not bringing the value from that control...Displaying as "cbLoginCompany" has 0 items i.e count=0;
Can u help me to come out of this issue...

Solution 3

Initialize in the constructor.

Solution : A field initializer cannot reference the nonstatic field, method, or property[^]
