combobox

问题 I believe this question is kinda new-bie, but I can't solve it in correct way. Brief description: I have an inherited from ComboBox class that does some data bindings in constructor: var mdl = new Model(); ValueMember = "id"; DisplayMember = "unit"; DataSource = mdl.getUnits(); All good here. The combobox is filled by required data. Then I have another form with a function editIngridient. The function is following; public bool editIngridient(int id) { currentId = id; var row = mdl

问题 this is closely related to this post: Is there an onSelect event or equivalent for HTML <select>? ...but specifically for the Dojo ComboBox..(I am using Dojo w/ ArcGIS JSAPI). I have three combo boxes, which populate the successors using queries triggered by the selections from the dropdown list.

But how to go about writing it and attaching that value to combobox. Problem : How it is now How I would like it to be. Just upon selection 回答1: Usually

问题 I want to get a result set with 2 fields from my DB. rs=Con.sqlQueryTable("Select id_prov, name_prov from prov"); And then I want to show the field called "name_prov" in the comboBox (As the item). But I also want to have my "id_prov" which is the ID (PRIMARY KEY) as the value for this item. This serves for the purpose of relating the name (of the providers in this case) with its ID just by using the combobox. This is the code of the JComboBox event FocusGained that Im currently using. try {

问题 I have a ComboBox with its ItemsSource set to an IList of MyClass objects. I overrode the ComboBox 's ItemTemplate to display a CheckBox next to the items. I want to have an item at the top that says "Select All" and when the user checks that CheckBox , the code checks all CheckBoxes . My question is, what is the MVVM way of doing this?

问题 I am facing a weird problem in IE which is not happening with other browsers.
