多个dataGridView应用程序的通用样式(一般设置)

Question

这个应用程序有多个dataGridViews。

示例.

有: dataGridView-3段(dataGridView1，dataGridView2，dataGridView3)。

如何做：

• dataGridView1-2 -有settings-1;
• dataGridView3 -有设置-2.

换句话说，我设置了哪个"dataGridView“使用哪些设置。

问题.

如何为多个dataGridView应用程序创建通用样式？

我创造了一个解决方案。结果：我得到一个空的UserControl

代码MyGrid

class MyGrid: DataGridView
    {
        public MyGrid ()
        {
             // this = new System.Windows.Forms.DataGridView ();
            // ((System.ComponentModel.ISupportInitialize) (this)). BeginInit ();
            //this.SuspendLayout ();
            //
            // dgw
            //
            this.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
            // this.dgv.Location = new System.Drawing.Point (20, 64);
            this.Name = "dgw";
            this.Size = new System.Drawing.Size (419, 173);
            // this.dgv.TabIndex = 0;
 
 
 
 
            // this.Columns ["Name"]. Width = 70; // Change the width. Field - "Name"
            // this.Columns ["Property"]. Width = 70; // Change the width. Field - "Property"
            // this.Columns [0] .Width = 70; // Change the width. Field - "Name"
            // this.Columns [1] .Width = 70; // Change the width. Field - "Property"
 
            this.RowHeadersWidth = 20; // Width "Title of rows"
            this.AllowUserToAddRows = false; // `false` - disable the line for adding a" new record "
            this.ReadOnly = true; // Editing
 
            this.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells; // Auto-fit width.
 
            this.SelectionMode = DataGridViewSelectionMode.FullRowSelect; // Select the entire line
            this.MultiSelect = false; // Multi-select
            this.Columns.Cast <DataGridViewColumn> () .ToList (). ForEach (f => f.SortMode = DataGridViewColumnSortMode.NotSortable); // Disable sorting
 
            // this.Size.Width = 400;
            // this.Size.Height = 170;
            
        }
 
    }

代码UserControl1

public partial class UserControl1 : UserControl
    {
        public UserControl1()
        {
            InitializeComponent();
 
            DataTable dt = new DataTable();
            
            dt.Columns.Add("Name", typeof(string));
            dt.Columns.Add("Property", typeof(string));            
 
            dt.Rows.Add("Name_1", "Property_1");
            dt.Rows.Add("Name_2", "Property_2");
            dt.Rows.Add("Name_3", "Property_3");
                 
            //
            MyGrid myGrid = new MyGrid();                
            myGrid.Location = new Point(20, 64);
            myGrid.TabIndex = 0;
 
            myGrid.DataSource = dt;
        }
    }

代码MainForm

namespace WinForm
{
    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
        }
 
        private void button1_Click(object sender, EventArgs e)
        {
            var userControl1 = new UserControl1();
            panel1.Controls.Clear();            
            panel1.Controls.Add(userControl1);           
 
        }
 
        private void button2_Click(object sender, EventArgs e)
        {
            var userControl2 = new UserControl2();
            panel1.Controls.Clear();
            panel1.Controls.Add(userControl2);
        }
    }
}

我认为最简单的方法是创建从DataGridView派生的类。将它们放入DLL中，您就可以从需要这些类的任何应用程序中访问它们。

public class DataGridView1 : System.Windows.Forms.DataGridView
{
    public DataGridView1() : base()
    {
        // Add columns, and set all styles specific for this kind of DataGridView
        this.BackColor = Colors.LightGreen;
        DataGridViewColumn columnId = new DataGridViewColumn()
        {
            Name = "columnId",
            Width = 20,
            ...
        this.Columns.Add(columnId);
        ...
    }
}

public class DataGridView1 : System.Windows.Forms.DataGridView
{
    public DataGridView2() : base()
    {
        // Add columns, and set all styles specific for this kind of DataGridView
        this.BackColor = Colors.Cyan;
        DataGridViewColumn columnId = new DataGridViewColumn()
        {
            Name = "columnId",
            Width = 50,
            ...
        this.Columns.Add(columnId);
        ...
    }
}

用法：

class MainForm : Form
{
    private readonly DataGridView1 dataGridView = new DataGridView1();
    ...
}
class OtherForm : Form
{
    private readonly DataGridView2 dataGridView = new DataGridView2();
    ...
}
