无法在vs [C＃，WPF]中将运行时创建的控件位置正确设置为光标位置 [英] Can't set runtime created controls position to cursor position correctly in vs [C#, WPF]

问题描述

我完成了一个简单的拖动控制功能，后来发现它只适用于设计/创建的控件，但不适用于运行时控件。当我单击/保持运行时控件时，其位置未正确设置到我的光标位置，它设置在距离光标稍远的右下方，但创建的控件工作正常。我想我将运行时控件添加到我的网格错误。这是我的xml，我将我的运行时控件添加到displaygrid。

I finished creating a simple drag control function and later found out that it only works on designed/created controls, but not runtime controls. When I click/hold a runtime control its position is not set correctly to my cursor position, it is set to right bottom a little far away from my cursor, but created controls works fine. I think I'm adding the runtime controls to my grid wrong. Here is my xml, I'm adding my runtime controls to the displaygrid.

<Window x:Class="MN.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:MN"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525" WindowStartupLocation="CenterScreen" Topmost="True" ResizeMode="NoResize" Background="{x:Null}" AllowsTransparency="True" WindowStyle="None">
    <Grid x:Name="displaygrid">
        <Rectangle Fill="#FFF4F4F5" Stroke="Black">
            <Rectangle.Effect>
                <BlurEffect Radius="25"/>
            </Rectangle.Effect>
        </Rectangle>
        <ListBox x:Name="tablist" Background="{x:Null}" FontSize="48" SelectionChanged="tablist_SelectionChanged"/>
    </Grid>
</Window>

我添加了这样的运行时控件

I added my runtime control like this

TextBlock newctrl = new TextBlock();
displaygrid.Children.Add(newctrl);
newctrl.Width = ctrl.width;
newctrl.Height = ctrl.height;
newctrl.Margin = new Thickness(ctrl.left, ctrl.top, 0, 0);
newctrl.Text = ctrl.text;
active_ctrls.Add(newctrl);
newctrl.PreviewMouseDown += enable_ctrldrag;

这样做是为了将我的控制移动到我的光标

And did this to move my control to my cursor

private bool MouseHook_OnMouseMove(int x, int y) // WinputManager Library
        {
            if (_selctrl != null)
            {
                //_selctrl.Margin = new Thickness(x, y, 0, 0);
                _selctrl.Margin = new Thickness(Mouse.GetPosition(this).X, Mouse.GetPosition(this).Y, 0, 0);
            }

            return false;
        }

我的尝试：



制作一个新项目并测试并发现我的问题+我在测试时没有使用任何库。

What I have tried:

Made a new project and tested and found out my problem + I didn't use any libraries when I was testing.

推荐答案

找到我的答案当我在WPF中搞乱时，通过添加VerticalAlignment = Top和Horizo​​ntalAlignment = Left来解决它

Found my answer when I was messing around in WPF, solved it by adding VerticalAlignment = Top and HorizontalAlignment = Left

TextBlock newctrl = new TextBlock();
displaygrid.Children.Add(newctrl);
newctrl.VerticalAlignment = VerticalAlignment.Top;
newctrl.HorizontalAlignment = HorizontalAlignment.Left;
newctrl.Width = ctrl.width;
newctrl.Height = ctrl.height;
newctrl.Margin = new Thickness(ctrl.left, ctrl.top, 0, 0);
newctrl.Text = ctrl.text;
active_ctrls.Add(newctrl);
newctrl.PreviewMouseDown += enable_ctrldrag;
