dataGridView图像不显示第一行，第二个单元格 [英] dataGridView Image not displaying for first row, second Cell

问题描述

好吧，所以我有一个dataGridView，我试图显示一个图像（使用DataGridViewImageColumn），所有相应的行都有图像，除了第一行（这也是我可以看到的唯一一行视觉工作室的编辑）下面的图像是我得到的，我希望他们都是绿色的复选标记。如何实现？

请注意，我已经尝试过以下操作：
在启动时更改或删除我的选择;
使用不同的图像;动态设置图像（代码）;和一些随机更改的设置。任何帮助将高度赞赏！我很感谢大家的帮助，请让我知道，如果我可以提供更多的信息。

解决方案

 code>命名空间WindowsFormsApplication1 
 {
 public partial class Form1：Form 
 {
 public Form1（）
 {
 InitializeComponent（）; 
} 
 
 private void button1_Click（object sender，EventArgs e）
 {
列表< MyItem> items = new List< MyItem>（）; （int i = 0; i< 10; i ++）
 {
 items.Add（new MyItem {Key = i，value = Image.FromFile（@e：\ test.jpg）}）; 
} 
 
 this.dataGridView1.AutoGenerateColumns = false; 
 this.dataGridView1.Columns.Clear（）; 
 this.dataGridView1.Columns.Add（Key，Key）; 
 this.dataGridView1.Columns.Add（new DataGridViewImageColumn（）{HeaderText =Status}）; 
 
 this.dataGridView1.Columns [0] .DataPropertyName =Key; 
 this.dataGridView1.Columns [1] .DataPropertyName =value; 
 
 this.dataGridView1.DataSource = items; 
 
} 
} 
 
 public class MyItem 
 {
 public int Key {get;组; } 
 public Image value {get;组; } 
} 
  

}

Okay so I have a dataGridView that I am trying to display an image on (using the DataGridViewImageColumn), all of the appropriate rows have the image, except for row one (this is also the only row that I can see in the visual studio's editor) The image below is what I am getting, I want all of them to be the green check mark though. How might I accomplish that?

Please note that I have already tried the following: Changing or removing my selection on start-up; Using a different image; Setting the image dynamically (in code); and a bit of randomly changing settings. Any help would be highly appreciated! I thank you all in advance for the help, please let me know if I can supply anymore information.

解决方案

   namespace WindowsFormsApplication1   
{
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        List<MyItem> items = new List<MyItem>();
        for (int i = 0; i < 10; i++)
        {
            items.Add(new MyItem { Key = i, value = Image.FromFile(@"e:\test.jpg") });
        }

        this.dataGridView1.AutoGenerateColumns = false;
        this.dataGridView1.Columns.Clear();
        this.dataGridView1.Columns.Add("Key", "Key");
        this.dataGridView1.Columns.Add(new DataGridViewImageColumn() { HeaderText="Status"});

        this.dataGridView1.Columns[0].DataPropertyName = "Key";            
        this.dataGridView1.Columns[1].DataPropertyName = "value";

        this.dataGridView1.DataSource = items;

    }
}

public class MyItem
{
    public int Key { get; set; }
    public Image value { get; set; }
}

}
