how does one set a default value for a bobox in OpenUI5? I tried the onAfterRendering method to dynamically set the key as well but nothing happens. I would gladly appreciate your help :)

XML View code:

<ComboBox id="GenderBox" type="Unstyled"
               maxWidth="8rem"
               items="{path: 'gender>/'}"
               selectionChange="changeGender">
               <core:Item key="{gender>val}" text="{gender>val}" />
</ComboBox> 

Javascript code

onAfterRendering: function(){
   var codebox = this.oView.byId("GenderBox");
   codebox.setSelectedKey("Male");
}

More Javascript code

var oView = this.getView();  
var oData = [];

oData[0] = {"val": "Female"};
oView.setModel(new sap.ui.model.json.JSONModel(oData),"gender");

Sorted by: Reset to default 4

I supose you mean using the property "selectedKey" as follows:

<ComboBox id="GenderBox" type="Unstyled"
               selectedKey="defaultSelectedKey"
               maxWidth="8rem"
               items="{path: 'gender>/'}"
               selectionChange="changeGender">
               <core:Item key="{gender>val}" text="{gender>val}" />
</ComboBox>

Where "defaultSelectedKey" must be the "val" of your model "gender" that you want to display as default.
