Question

I’m having a Windows Forms application with a combobox. I added items to the combobox (for example, 1,2,3,4). If I select an item in the combobox SelectedIndex should be returned to the variable in another class.

class Form1
{
    private void Combobox1_SelecetedIndexChanged(object sender,eventArgs e)
    {
        combobox1.selecetdeIndex ; //I will get the selected index.
        //If the selected index is changed then the currentValue in the AnotherClass should be 
        //changed.
    }
}

Class AnotherClass
{
    private int currentValue;
    //There are some methods which depends on currentValue.
}

Answer 1

Something along these lines: (pseudocode)

class SomeClass
{

  public int comboindex
  {
    get; set;
  }

}

SomeClass c = new SomeClass();

c.comboindex = mycombo.selectedindex;
