winforms - C# ComboBox change active status -


i have 5 combobox controls , when item selected in combobox 1, new list created in combobox 2, , on down combobox 5. need change active status according current selected item. items not selected way of selectedindexchanged event in button click event handler. have been working on code have reached impasse. here code:

///////////combo1////////////////////// int selectedindex1 = combobox1.selectedindex; object selecteditem1 = combobox1.selecteditem;                                 if (selecteditem1.tostring() == "computers") {         selecteditem1 = "32";     request.categoryid = selecteditem1.tostring();     }  ///////////combo2////////////////////// int selectedindex2 = combobox2.selectedindex; object selecteditem2 = combobox2.selecteditem;             if (selecteditem2.tostring() == "laptop") {     selecteditem2= "1772";     request.categoryid = selecteditem2.tostring(); }

the problem when not use combobox 2 selected item , not cancel combobox 1 selected item. need supersede previous combobox selected item.

private void combobox1_selectedindexchanged(object sender, eventargs e) {  object selecteditem1 = combobox1.selecteditem;  combobox2.enabled = true;  combobox3.enabled = false;  combobox4.enabled = false;  combobox5.enabled = false;   if(selecteditem1.tostring() == "computers")  {    //update data source combobox2 relevant data "computers"  }   //remove data combobox3 4 , 5 witch disabled }

repeat idea rest.
