c# - How can I get the selected item of a dropdownlist, the first time my page loads? -

i'm looking solution first selected item in dropdownlist. , want when page loads first time.

thank in advance.

edit: call method @ load-event ddlniveau2 remains empty. think ddlniveau1.selectedvalue isn't accessed.

public void filllistniveau2() {     ddlniveau2.items.clear();     foreach (var item in dbal.getlistniveau2(ddlniveau1.selectedvalue))     {         ddlniveau2.items.add(item.tostring());     }     removeduplicateitems(ddlniveau2); } 

there databound event, fires after data bound dropdown. assigning datasource dropdown need selected item after rows binded dropdown

protected void dropdownlist1_databound(object sender, eventargs e) {     dropdownlist1.selectedvalue // store in variable }
