Question

我需要一些用户控件的帮助。我有一个具有自定义ControlDesigner的用户控件：

在设计器中，如果我在用户控件上更改了特定属性，我会更改SelectionRules。

我遇到的问题如下：当我放置此用户控件的多个副本并更改属性时，设计器将更改所有副本的SelectionRules。

如何为每个副本设置此项？

以下是代码：

[Designer(typeof(BorderedTextBox_Designer))]
public partial class BorderedTextBox : UserControl
{
    [Browsable(true), EditorBrowsable(EditorBrowsableState.Always)]
    [Description("Controls whether the text of the edit control can span more than one line.")]
    [Category("Behavior")]
    [DefaultValue(false)]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
    public bool Multiline
    {
        set
        {
            //Set to TRUE:
            if (value)
            {
                BorderedTextBox_Designer.SelectionRule = BorderedTextBox_Designer.SelectionRulesEnum.All;
            }
            //Set to FALSE:
            else
            {
                BorderedTextBox_Designer.SelectionRule = BorderedTextBox_Designer.SelectionRulesEnum.RightLeft;
            }
        }
    }
}

internal class BorderedTextBox_Designer : ControlDesigner
{
    internal static SelectionRulesEnum SelectionRule;

    public override SelectionRules SelectionRules
    {
        get
        {
            switch (SelectionRule)
            {
                case SelectionRulesEnum.All:
                    return SelectionRules.Visible | SelectionRules.Moveable | SelectionRules.AllSizeable;
                case SelectionRulesEnum.UpDown:
                    return SelectionRules.Visible | SelectionRules.Moveable | SelectionRules.TopSizeable | SelectionRules.BottomSizeable;
                case SelectionRulesEnum.RightLeft:
                    return SelectionRules.Visible | SelectionRules.Moveable | SelectionRules.LeftSizeable | SelectionRules.RightSizeable;
                case SelectionRulesEnum.None:
                    return SelectionRules.Visible | SelectionRules.Moveable;
                default:
                    return SelectionRules.Visible | SelectionRules.Moveable;
            }
        }
    }

    internal enum SelectionRulesEnum
    {
        All,
        UpDown,
        RightLeft,
        None
    }
}

我已经弄清楚了。感谢Sinatr提示：）

答案是从用户控件将属性设置为ControlDesigner的实例。

而不是静态类=＆gt;在这种情况下，属性变化将是全局的，因为我的问题是。

这是一个代码示例：

var bardata = [];

d3.tsv('data.tsv', function(data){

    for (key in data){
        bardata.push(data[key].value)
  }
    
    
    var margin = {top:30, right:30, bottom:40, left:50}

var height = 400 - margin.top - margin.bottom,
  width = 400 - margin.left - margin.right,
  barWidth = 50,
  barOffset = 5;
var tempColor;

var yScale = d3.scaleLinear()
  .domain([0, d3.max(bardata)])
  .range([0, height]);

var xScale = d3.scaleBand()
  .domain(d3.range(0, bardata.length))
  .padding(0.1)
  .range([0, width]);

var tooltip = d3.select('body').append('div')
.style('position', 'absolute')
.style('padding', '0 10px')
.style('background', 'white')
.style('opacity', 0)

var myChart = d3.select('#chart').append('svg')
.style('background', '#E7E0CB')
  .attr('width', width + margin.right + margin.left)
  .attr('height', height + margin.top + margin.bottom)
  .append('g')
  .attr('transform', 'translate('+ margin.left +', '+ margin.top +')')
  .style('background', '#C9D7D6')
  .selectAll('rect').data(bardata)
  .enter().append('rect')
  .style('fill', '#C61C6F')
  .attr('width', xScale.bandwidth())
  

.attr('x', function(d, i) {
    return xScale(i);
  })
.attr('height', 0)
.attr('y', height)

.on('mouseover', function(d){
    d3.select(this)
    .style('opacity', 0.5)
})
.on('mouseleave', function(d){
    d3.select(this)
    .style('opacity', 1)
})
.on('mouseover', function(d){
    tooltip.transition()
    .style('opacity', 0.9)
    tooltip.html(d)
    .style('left', (d3.event.pageX - 35) + 'px')
    .style('top', (d3.event.pageY - 30) + 'px')
    
    tempColor = this.style.fill;
    d3.select(this)
    .style('opacity', 0.5)
    .style('fill', 'yellow')
})
.on('mouseleave', function(d){
    tempColor = this.style.fill;
    d3.select(this)
    .style('opacity', 1)
    .style('fill', '#C61C6F')
})

myChart.transition()
.attr('height', function(d){
    return yScale(d);
})
.attr('y', function(d){
    return height - yScale(d);
})
.delay(function(d, i){
    return i * 20;
})
.duration(1000)
.ease(d3.easeElastic)

var vGuideScale = d3.scaleLinear()
  .domain([0, d3.max(bardata)])
  .range([0, height]);

var vAxis = d3.axisLeft(vGuideScale).ticks(10)

var vGuide = d3.select('svg').append('g')
vAxis(vGuide)

vGuide.attr('transform', 'translate('+ margin.left +', '+ margin.top +')')

var hAxis = d3.axisBottom(xScale).tickValues(xScale.domain().filter(function(d,i){
    return !(i % (bardata.length/5))
}))

var hGuide = d3.select('svg').append('g')
hAxis(hGuide)

hGuide.attr('transform', 'translate('+ margin.left +', '+ (height + margin.top) +')')

});

C＃用户控件使用自定义ControlDesigner的每个副本
