Disable item inside combo box SAPUI5

问题

I have a combo box with, let's say, 2 items.

one of the items has relevant data to report, and the other doesn't.

How would I grey out the unwanted item in the combo box?

I can grey out the entire combo box, but I'm not sure how to grey out items inside a combo box (this combo box is populated by an ODATA call).

回答1:

You can set the items of the combo box to the disabled as follows:

Want to disable the selected item from combo box list:

this.getView().byId("idOfYourComboBox").getSelectedItem().setEnabled(false);

Based on the index of the items in the list.

this.getView().byId("idOfYourComboBox").getItems()[1].setEnabled(false);

Also, you can do the same thing based on the key like:

this.getView().byId("idOfYourComboBox").getItemByKey("keyName")

Let me know if this helps.

You can use the property enabled of sap.ui.core.Item. Updated your oData and add one more boolean property like isRelevant which tell which item is enabled/disabled.

XML View

<ComboBox items="{path: '/YourBindingPath'}">
  <core:Item key="{key}" text="{text}" enabled="{enabledProperty}" />
</ComboBox>

JS view

var oItemTemplate = new sap.ui.core.ListItem({
  key: "{key}", 
  text: "{text}", 
  enabled: "{enabledProperty}"
});
var oComboBox = new sap.m.ComboBox({
  items: { 
    path: "/YourBindingPath", 
    template: oItemTemplate 
  }
});
