グリッドビューで選択した行の値を別のフォームのテキスト ボックスに渡すために使用したコードのサンプルを以下に示します。シナリオがあります：私は2つのフォームを持っています。最初のフォームにはボタンとテキストボックスが含まれており、ボタンは2番目のフォーム「フォーム2」を開きます。form2 には Xtragrid が含まれています。このフォームから、ダブルクリック イベントを実行して、選択した各行の値を最初のフォームにロードします。

よく私はあなたのアプローチで私のコードを修正しましたが、何もうまくいっていません、多分私はいくつかのものを見落としているかもしれません.

私のアプローチは、イベントを使用し、データを含むフォームにイベントを作成し、表示する値を含むカスタム イベント引数を作成することです。以下のコードは、私がそれを行った方法を示しています。これが役立つことを願っています

ここで解決策を見つけることができます

//Issue
public class Issue
{
    public string Value1 { get; set; }
    public int Value2 { get; set; }
}

//My custom evenntArgs
public class CustomDoubleClickEventArgs : EventArgs
{
    public Issue Issue { get; set; }
}

//Form 2 : Containing the xtragrid

public event EventHandler<CustomDoubleClickEventArgs> CustomViewDoubleClick;

//Handle the view double click event
private void GridView_DoubleClick(object sender, EventArgs e)
{
    if (CustomViewDoubleClick == null)
        return;

    CustomViewDoubleClick(this, new CustomDoubleClickEventArgs() 
    { 
        Issue = new Issue() 
        {  
            //You can use GetFocusedRowCellValue(col) rather than GetRowCellValue(handle, col)
            Value1 = GridView.GetFocusedRowCellValue("Name").ToString(),
            Value2 = Convert.ToInt32(GridView.GetFocusedRowCellValue("Age"))
        }
    });
}

//Form 1 : Showing the focused row data
Form2 form2;
private void Form1_Load(object sender, EventArgs e)
{
    form2 = new Form2();
    form2.CustomViewDoubleClick += OnDoubleClick;
}

private void OnDoubleClick(object sender, CustomDoubleClickEventArgs args)
{
    txFirstName.Text = args.Issue.Value1;
    txAge.Text = args.Issue.Value2.ToString();
}

private void bnShowData_Click(object sender, EventArgs e)
{
    form2.Show();
}
