Infragistics上的Enter键可编辑Wingrid

Question

我有一个屏幕，其中包含infragistics窗口可编辑网格和winforms按钮。 在Enter键上，新行被添加到ultrawin网格中。相反，我需要启动winforms按钮事件。

只有在选项卡上，它应该导航到下一个单元格，当它到达最后一个单元格时，它应该导航到下一行。

在新的行模板即将提交之前，您可以处理UltraGrid的BeforeRowUpdate事件并调用UltraButton的执行点击。

public partial class Form1 : Form 
{ 
    private bool _IsEnterKeyDown = false; 

    public Form1() 
    { 
     InitializeComponent(); 
    } 

    private void Form1_Load(object sender, EventArgs e) 
    { 
     ultraGrid1.KeyDown += new KeyEventHandler(ultraGrid1_KeyDown); 
     ultraGrid1.BeforeRowUpdate += new CancelableRowEventHandler(ultraGrid1_BeforeRowUpdate); 
     ultraGrid1.InitializeLayout += new Infragistics.Win.UltraWinGrid.InitializeLayoutEventHandler(ultraGrid1_InitializeLayout); 
     ultraGrid1.DataSource = GetDataTable(); 
    } 

    private void ultraGrid1_KeyDown(object sender, KeyEventArgs e) 
    { 
     if (e.KeyData == Keys.Enter) 
     { 
      _IsEnterKeyDown = true; 
     } 
    } 

    private void ultraGrid1_BeforeRowUpdate(object sender, CancelableRowEventArgs e) 
    { 
     if (e.Row.IsAddRow && _IsEnterKeyDown) 
     { 
      _IsEnterKeyDown = false; 
      ultraButton1.PerformClick(); 
     } 
    } 

    private void ultraButton1_Click(object sender, EventArgs e) 
    { 
     MessageBox.Show("Button click event raised!"); 
    } 

    private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e) 
    { 
     e.Layout.Override.AllowAddNew = AllowAddNew.TemplateOnBottom; 
    } 

    private DataTable GetDataTable(int rows = 10) 
    { 
     DataTable table = new DataTable("Table1"); 

     table.Columns.Add("Boolean column", typeof(bool)); 
     table.Columns.Add("Integer column", typeof(int)); 
     table.Columns.Add("DateTime column", typeof(DateTime)); 
     table.Columns.Add("String column", typeof(string)); 

     for (int i = 0; i < rows; i++) 
     { 
      DataRow row = table.NewRow(); 
      row["Boolean column"] = i % 2 == 0 ? true : false; 
      row["Integer column"] = i; 
      row["String column"] = "text"; 
      row["DateTime column"] = DateTime.Today.AddDays(i); 
      table.Rows.Add(row); 
     } 

     return table; 
    } 
}
