asp.net - Initial selection for a DropDownList overriding user selection -

i'm trying set initial selection dropdownlist calling: drop.selectedindex = 5 in page_load. works, if change selection manually , want save form, i'm still getting initial selection instead of new selection when calling drop.selectedvalue. what's wrong?

you have forgotten check if(!ispostback). otherwise select 6th item again on postbacks before selectedindexchanged event triggered (or button-click event):

protected void page_load(object sender, eventargs e) {     if(!ispostback)   // on initial load , not on postbacks         dropdwonlist1.selectedindex = 5; }
