问题 I'm still pretty new to VBA, but I have two activex listboxes on a worksheet. On one listbox I have salesperson names (called lstNames) and the other listbox has locations (lstSite). What I'm trying to achieve is the following: Select name from lstNames Selection from lstNames generates lstSite with a list of a few locations associated with the name. For example, if I select Bob from the lstNames listbox, then the lstSites listbox will populate all of Bob's sites like NY, CO, CA, PA. If I

C# WPF ViewModel for a class with List

由 只谈情不闲聊 提交于 2019-12-08 11:03:06
问题 I have a class with a list of items, something like this: public class Model{ List<int> Items { get; set; } } It uses List, not ObservableCollection, and doesn't have any events to be subscribed to. I need to make a ListBox oneway-bound to this list and a way to remove items one-by-one. So I must write a ViewModel class, a property of which can be oneway-bound to ListBox to show these items and to update the ListBox when the list is changed with RemoveItem method. I don't know how to oneway

Silverlight how to promote selected item of listbox when using buttons within datatemplates

由 人盡茶涼 提交于 2019-12-08 10:28:07
问题 Within a Listbox control I have a Data Template which consists of text and a button. Given the nature of Silverlight/WPF when I click on the button within the listbox item the button event is trapped before the listbox item is selected. Therefore if I am trying to pass the record ID of the selected listbox item I am currently only able to do so by first clicking and selecting the listbox item and then clicking on the button. Is there a way to promote the selection of the listbox item so that

WPF Style Triggers: can I apply the one style for a variety of Properties?

由 独自空忆成欢 提交于 2019-12-08 07:57:55
问题 It seems like there has to be a way to do this: I am applying an ItemContainerStyle in my Listbox, based on two property triggers. As you can see, I'm using the exact same set of trigger enter/exit actions, simply applied on two different properties. Is there something equivalent to a <Trigger Property="prop1" OR Property="prop2"> ??? (Obviously wouldn't look like that, but that probably gets the point across.) <Style x:Key="ListBoxItemStyle" TargetType="ListBoxItem"> <Style.Triggers>

问题 I have a simple aspx page with a textbox, linkbutton and listbox. The listbox is to be populated with values from a stored procedure in a SQL database. What I'd like to do, somehow, is to populate the listbox with those variables when the user clicks the linkbutton. Ideally, I'd like to do this WITHOUT a postback. Is there any way this can be accomplished? Thanks, Jason 回答1: I mocked one up for you really quickly. <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat=
