Question

当我点击 button 时,我想在 showRichMessageBox 中显示一个特定的单元格值,但是如果单击行的任意位置,此事件会显示单元格值。...!!

我怎样才能解决上述问题?

I have some logvalues which are big but it s already loaded in the cell so, Is it possible to expand the row when i select a particular row in the datagridview???

 public LogView()
    {
        InitializeComponent();
        this.dataGridView2.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView2_buttonCol);

        bindingList = new SortedBindingList<ILogItemView>();
        dataGridView2.DataSource = bindingList;
        this.dataGridView2.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
        this.dataGridView2.MultiSelect = false;
        var buttonCol = new DataGridViewButtonColumn(); // The button to display a particular cell value when clicks//
        buttonCol.Name = "ButtonColumnName";
        buttonCol.HeaderText = "Show";
        buttonCol.Text = "View";
        buttonCol.UseColumnTextForButtonValue = true;    
        dataGridView2.Columns.Add(buttonCol);

    }

    private void dataGridView2_buttonCol(object sender, DataGridViewCellEventArgs e)
    {

            string name = Convert.ToString(dataGridView2.SelectedRows[0].Cells[2].Value);
            ShowRichMessageBox("Code", name);

    }

编辑 :

if (e.ColumnIndex != 0) // Change to the index of your button column
            {
                return;
            }

            if (e.RowIndex > -1)
            {
                string name = Convert.ToString(dataGridView2.Rows[e.RowIndex].Cells[2].Value);
                ShowRichMessageBox("Code", name);
            }

像这样:

private void dgv_buttonCol(object sender, DataGridViewCellEventArgs e)
{
        if (e.ColumnIndex != 4) // Change to the index of your button column
        {
             return;
        }

        if (e.RowIndex > -1)
        {
            string name = Convert.ToString(dgv.Rows[e.RowIndex].Cells[2].Value);
            ShowRichMessageBox("Code", name);
        }
}

对于你问题的第二部分,我不知道你的意思是什么,但你肯定可以改变行高度,也许在选择更改的事件中使用,或者如果你想做更深入的事情,请参看,http://msdn.microsoft.com/en-us/library/85kxkk29c.aspx" rel=“nofollow””“如何:自定义窗口形式 DataGridView Control 中行的外观”
