如何覆盖列表视图中所选行的前景色 [英] How to override the forecolor of a selected row in a listview

问题描述

我有一个列表视图，其中一些前景颜色是红色的，具体取决于某些标准。我注意到，当选择一行时，前景色为黑色，无论未选择时前景是否为红色。当选择与未选择时相同的颜色时，我如何才能使行的前景颜色为
？我在selectedindexchanged事件处理程序中尝试了类似的东西，它没有工作

I have a listview in which some of the rows forecolor are red depending on certain criteria. I noticed that while a row is selected the forecolor is black regardless if the forecolor is red when not selected. How would I be able to make the row's forecolor when selected the same color as when not selected? I tried something like this in the selectedindexchanged event handler and it did not work

if (listView1.SelectedItems.Count > 0)
{
    listView1.SelectedItems[0].ForeColor = System.Drawing.Color.Blue;
}

我调试了它并且它通过了代码，但它仍然没有在选择之前将forecolor更改为颜色。如果未选中，我怎样才能使所选行的前景色与行相同？

I debugged it and it went through the code but it still did not change the forecolor to color it was before selecting. How would I be able to make the forecolor of the selected row be the same forecolor as the row when not selected?

Hello Debra，

Hello Debra,

我对此问题进行了测试， ForeColor按预期更改。怎么样通过一些代码或图像向我展示你的结果？

I have a test about this issue and the ForeColor is changed as expected. What about show me your result by some more code or image?

这是我的测试样本：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace TextboxTest
{
    public partial class ListViewcs : Form
    {

        ListView listView1 = new ListView();
           

        public ListViewcs()
        {
            InitializeComponent();
            // Create a new ListView control.
           
            
            listView1.Bounds = new Rectangle(new Point(10, 10), new Size(300, 200));

            // Set the view to show details.
            listView1.View = View.Details;
            // Allow the user to edit item text.
            listView1.LabelEdit = true;
            // Allow the user to rearrange columns.
            listView1.AllowColumnReorder = true;
            // Display check boxes.
            listView1.CheckBoxes = true;
            // Select the item and subitems when selection is made.
            listView1.FullRowSelect = true;
            // Display grid lines.
            listView1.GridLines = true;
            // Sort the items in the list in ascending order.
            listView1.Sorting = SortOrder.Ascending;

            



            // Create three items and three sets of subitems for each item.
            ListViewItem item1 = new ListViewItem("item1", 0);
            // Place a check mark next to the item.
            item1.Checked = true;
            item1.SubItems.Add("1");
            item1.SubItems.Add("2");
            item1.SubItems.Add("3");
            ListViewItem item2 = new ListViewItem("item2", 1);
            item2.SubItems.Add("4");
            item2.SubItems.Add("5");
            item2.SubItems.Add("6");
            ListViewItem item3 = new ListViewItem("item3", 0);
            // Place a check mark next to the item.
            item3.Checked = true;
            item3.SubItems.Add("7");
            item3.SubItems.Add("8");
            item3.SubItems.Add("9");

            // Create columns for the items and subitems. 
            // Width of -2 indicates auto-size.
            listView1.Columns.Add("Item Column", -2, HorizontalAlignment.Left);
            listView1.Columns.Add("Column 2", -2, HorizontalAlignment.Left);
            listView1.Columns.Add("Column 3", -2, HorizontalAlignment.Left);
            listView1.Columns.Add("Column 4", -2, HorizontalAlignment.Center);

            //Add the items to the ListView.
            listView1.Items.AddRange(new ListViewItem[] { item1, item2, item3 });
            

            this.Controls.Add(listView1);
           
        }

        private void button1_Click(object sender, EventArgs e)
        {
            listView1.SelectedItems[0].ForeColor = System.Drawing.Color.Red;
        }

      

       


    }
}

这是我的结果：

那时候你没有选择任何项目，所以颜色没有变化吗？

Will it be that you haven't select any item at that time so the color doesnot changed?
