问题 I have a listbox called lstSerial and a textbox called txtSerials. What I want to do is search lstSerial for the string that's entered in txtSerials. I'm using VB6 in Microsoft Visual Basic 6.0, and I'm having a terrible time finding documentation. Thanks. 回答1: @AlexK's answer is technically correct - yes - it will work, but it's not the preferred way to go. There is an API call for this very purpose: Private Declare Function SendMessage Lib "USER32" Alias "SendMessageA" _ (ByVal hWnd As Long

问题 I have a ListBox which I need to gray out when it's disabled. Per user request it's not enough to disable it, but it also has to appear differently. shrugs I've looked in several other places and followed the examples, and it seems as if it should work, but it does not. Here are some examples I looked at: Example1, Example2. Here is my code: <Style x:Key="ListBoxStyle" TargetType="ListBox"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type ListBox}">

Listbox scrollbar thumb changes size when content is variable height

由 妖精的绣舞 提交于 2019-12-09 00:45:38
问题 I have a ListBox with many objects displayed, each of which can be a variable height, based on the number of values each object has. See my previous question that was answered here. Many objects are 5-lines high, while others are 1. The scroll bar in the ListBox does not appear to like this, probably due to the virtualization. While you scroll through, the thumb on the scroll bar will change its size , based on how many items are actually fitting into the box at that current moment. This

Validating a ListBoxItem rather than a ListBox

由 主宰稳场 提交于 2019-12-08 12:58:26
I have a ListBox bound to a list of objects that implement IDataErrorInfo. I have set the ValidatesOnDataErrors property to True on my ListBox. If I select an invalid item, a red border appears around my ListBox. How can I modify my ItemContainerStyle such that the red border appears arround the selected item rather than the actual ListBox? You can set ValidatesOnDataErrors in the ListBox's ItemTemplate directly, on the Binding which binds the bound item's property to the control that displays it. That should make the red border show up around the control in question. If, in addition to that,
