问题 I have a Border, and i'm trying to to make it's BorderBrush Flashes "Fade in and out". But my problem, is that the Flasing color depends on the code behind. so the color will change, but i have to keep the fade in/out forever, with changing the "From" color of this Border. I tried in two ways: 1: binding the color directly, but then i know that there's a freezing thing the is needed to be applied on the color: <Border Grid.Column="1" Grid.Row="2" Name="ActiveBorder" VerticalAlignment="Stretch

问题 I have a datagrid bound to an ObservableCollection, and what I'd like to do is highlight new rows when they are added to the datagrid (i.e. when a new object is inserted into the ObservableCollection). I'd like to highlight the rows when they are inserted by changing the background colour initially, but then having the colour fade back to normal over time. I've tried a variety of different methods to get it to work but nothing quite works properly. Method 1: I have an event trigger that fires

问题 I'm using a button where I've shaped it, in its ControlTemplate. I've also added a storyboard in the controlTemplate. The storyboard changes the boarder of the element in my controlTemplate. I access this from the code behind and activate it, the problem is when I do this on the phone there is a lag. I've structured my code after the MVVM structure, my view is: <Button x:Name="Button1" BorderThickness="0" BorderBrush="Transparent"> <Button.Template> <ControlTemplate x:Name="Control"> <Path x

问题 I wonder if someone can help me - I've got a label which I need to be able to cross-fade between any 2 colors when a method is called in the code behind.

由 杀马特。学长 韩版系。学妹 提交于 2019-12-04 23:25:33
问题 Is it possible to increment or decrement hex color values on a step-by-step basis in jQuery / javascript? What I would like to do is something like this: Adapting from a for-loop like for (var i = 0; i <= 100; i++) { console.log(i); } I would like to do something like for (var color = 000000; color <= ffffff; color++) { console.log(color); } without any conversion. Is that possible? I've allready tried this: for (var color = parseInt('000000', 16); color <= parseInt('ffffff', 16); color++){
