c#将datagridview绑定到表格与控件的数据表

我有以下代码:

        DataGridView lGrid = new DataGridView();
        BindingSource _bind = new BindingSource();
        DataTable Table = new DataTable();

        this.Controls.Add(lGrid);
        lGrid.AutoGenerateColumns = true;


        List<string> ColumnsNames = new List<string>();
        ColumnsNames.Add("ID");
        ColumnsNames.Add("NAME");

        foreach (string Name in ColumnsNames)
            Table.Columns.Add(Name);

        DataColumn col = Table.Columns["ID"];
        DataColumn[] keys = new DataColumn[1];
        keys[0] = Table.Columns["ID"];
        Table.PrimaryKey = keys;

        lGrid.DataSource = _bind;
        _bind.DataSource = Table;

        int i = lGrid.Columns.Count;

使用在表单构造函数中执行的代码,用数据表中的列填充lGrid。但是,当我将它移动到控件构造函数时,绑定不起作用,并且i = 0.为什么会这样,我该怎么办呢?

行。构造函数是最简单的

公共部分类Form1:表单     {

    public Form1()
    {
          InitializeComponent();
         //CODE GOES HERE
    }
}

VS

public class mycontrol : Control
{
    public mycontrol()
    {
        //CODE GOES HERE
    }
}


public partial class Form1 : Form
{

    public Form1()
    {
          InitializeComponent();

          mycontrol ll = new mycontrol();
          this.Controls.Add(ll);
    }
}

答案 0 :(得分:1)

使用think if you

lDataGrid.Bind();

然后你会得到Count()

或检查AfterDataBinding事件上的Count。
