Question

所以我使用c＃在Win-forms上做一个项目，并且我将这个DataGridView锚定在面板的每个左侧和右侧。出于某种原因，DataGrid的右侧由于某种原因未呈现。（图片在下面的链接中）

如果我在运行时重新调整我的PC分辨率将解决问题有谁知道为什么会出现这个问题？

数据网格初始化为

this.dataGridView1 = new System.Windows.Forms.DataGridView();
this.dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;

this.dataGridView1.AllowUserToAddRows = false;
this.dataGridView1.AllowUserToDeleteRows = false;
this.dataGridView1.AllowUserToResizeColumns = false;
this.dataGridView1.AllowUserToResizeRows = false;
this.dataGridView1.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) 
| System.Windows.Forms.AnchorStyles.Left) 
| System.Windows.Forms.AnchorStyles.Right)));
this.dataGridView1.BackgroundColor = System.Drawing.Color.SandyBrown;
this.dataGridView1.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.DisableResizing;
 this.dataGridView1.Location = new System.Drawing.Point(43, 256);
this.dataGridView1.Name = "dataGridView1";
this.dataGridView1.RowTemplate.Height = 24;
this.dataGridView1.Size = new System.Drawing.Size(1167, 349);

Answer 1

使用你的代码看起来窗口的大小，与网格的位置和大小相关是罪魁祸首。表单窗口必须足够大以容纳整个网格。

我已经通过在Grid初始化中添加此行来解决您的问题。

Size = new Size(dataGridView1.Location.X + dataGridView1.Width + 25, dataGridView1.Height + dataGridView1.Location.Y + 125);

这是我的完整测试用例。

using System.ComponentModel;
using System.Drawing;
using System.Windows.Forms;

namespace DGVBiggerThanContainer_48112281
{
    public partial class Form1 : Form
    {
        DataGridView dataGridView1 = new DataGridView();
        BindingList<dgventry> dgvdata = new BindingList<dgventry>();
        public Form1()
        {
            InitializeComponent();


            //comment or uncomment appropriate line to
            //trigger the desired behavior
            FixedInit();
            //origInit();


            Controls.Add(dataGridView1);
            dataGridView1.DataSource = dgvdata;

            for (int i = 0; i < 10; i++)
            {
                dgvdata.Add(new DGVBiggerThanContainer_48112281.dgventry
                {
                    col1 = $"col1row{i}",
                    col2 = $"col2row{i}",
                    col3 = $"col3row{i}",
                    col4 = $"col4row{i}",

            this.dataGridView1.RowTemplate.Height = 24;
            this.dataGridView1.Size = new System.Drawing.Size(1167, 349);

            Size = new Size(dataGridView1.Location.X + dataGridView1.Width + 25, dataGridView1.Height + dataGridView1.Location.Y + 125);
        }
    }


    public class dgventry
    {
        public string col1 { get; set; }
        public string col2 { get; set; }
        public string col3 { get; set; }
