I have a ListViewItem that I am applying a Style to and I would like to put a dotted grey line as the bottom Border . How can I do this in WPF? I can only see solid color brushes. This worked great in our application, allowing us to use a real Border and not mess around with Rectangles: <Border BorderThickness="1,0,1,1"> <Border.BorderBrush> <DrawingBrush Viewport="0,0,8,8" ViewportUnits="Absolute" TileMode="Tile"> <DrawingBrush.Drawing> <DrawingGroup> <GeometryDrawing Brush="Black"> <GeometryDrawing.Geometry> <GeometryGroup> <RectangleGeometry Rect="0,0,50,50" /> <RectangleGeometry Rect="50

由 百般思念 提交于 2019-11-27 15:56:39
问题 An activity has a Button and a ListView. Initially, only the Button is visible. When the button is pressed, the ListView is displayed. When displayed, is it possible for me to show one particular item as selected/focussed? A use case could be that suppose it is a list of language settings and when the list opens, the currently selected language must be shown as highlighted. If I know the index of the item, how to set it as focused on display? 回答1: In short, ListView::setSelection(int position

由 纵饮孤独 提交于 2019-11-27 13:43:27
问题 I want to change the Item's/Row's height in listview. I searched every where and I figured that in order to change the height I need to use LBS_OWNERDRAWFIXED or MeasureItem or something like that. The problem is that I dont know exactly what to do and how to use it.. Can anyone help me with it? Edit: I cant use the ImageList hack because I am using the SmallImageList for real and I need different line height from the ImageList images size. Thanks! 回答1: It can be done using the SmallImageList

Get single listView SelectedItem

由 独自空忆成欢 提交于 2019-11-27 09:04:58
I have the MultiSelect property of the listView set to false and I'm trying to get a single listViewItem. But the available property is SelectedItems . I've been using the following code... foreach (ListViewItem item in listView1.SelectedItems) { //do something with item.text or whatever } Because I know there will only be one item selected. What is the correct way of doing this? Vogel612 Usually SelectedItems returns either a collection, an array or an IQueryable . Either way you can access items via the index as with an array: String text = listView1.SelectedItems[0].Text; By the way, you

Buggy ListView makes me sad

由 风流意气都作罢 提交于 2019-11-27 06:53:39
I have a ListView where I've defined the layout of each item in a separate XML file. In this file I've included a RatingBar and an EditText . I've programmatically created 7-8 items in this ListView . When I scroll through them, it seems to be quite buggy. Here are some examples: If I set focus to the EditText in the first row and then scroll down the ListView , random EditTexts from other rows will have focus. It seems to be that the next EditText after the focused one disappears receives focus. Perhaps this is intentional, but, as a user, it seems very weird. If I set focus to an EditText ,

WPF ListView - how to add items programmatically?

问题 Even if I know it's not ideal - I need to programmatically populate a listView (for whatever reason).
