asp.net - Angularjs inlcudes an empty option in select -

-

i have dropdownlist data being bound dynamically way @ page_load:

<asp:dropdownlist id="ddlset" datatextfield="title" datavaluefield="pksetid" runat="server"  appenddatabounditems="true" ng-model="setid"></asp:dropdownlist>

the rendered html :

<select id="cpcontent_ddlset" ng-model="setid"> <option value="? undefined:undefined ?"></option> <option value="3">test3</option> </select>

the option test3 should selected default when page loads, isn't happening. have set $scope.setid=3, don't know value before hand.

i see similar questions here dropdownlists data bound angular way, can set selected item $scope.

how tackle this.

either build server side asp application or build client side angular application, don't mix 2 technologies.

let angular whole frontend logic , rendering , asp provide rest services.

see angulars select example how preselect dropdown value.
