如何在数据网格视图中使用selectionchanged事件?

问题描述：

我在Windows应用程序中使用了一个数据网格视图和两个文本框以及两个按钮，一个按钮用于保存，另一个按钮用于更新.保存数据后，它将显示在数据网格视图中.然后，当我单击datagridview的单元格时，将使用selectionchanged事件在文本框中显示数据.

Hi,

I have used a one data gridview and two text box and two button in a form of windows application, one button for Save and other one for Update.After Save the datas, it will be display in data gridview. and then when i click the cell of datagridview,the data will display in the text box by using selectionchanged event.

private void dgvService_SelectionChanged(object sender, EventArgs e)
       {
           txtService.Text = dgvService.CurrentCell.Value.ToString();
           label2.Text = dgvService.CurrentCell.Value.ToString();
       }

通过上面的示例，我只能显示一列，但是当我单击一行时，数据gridview的第一列应显示在第一个文本框中，数据gridview的第二列应显示在第二个文本框中.
对于这个问题，请给我答案.

谢谢，

处理DataGridView.SelectionChanged事件:

Handle the DataGridView.SelectionChanged event:

private void myDataGridView_SelectionChanged(object sender, EventArgs e)
    {
    DataGridView dgv = sender as DataGridView;
    if (dgv != null && dgv.SelectedRows.Count > 0)
        {
        DataGridViewRow row = dgv.SelectedRows[0];
        if (row != null)
            {
            myFirstTextBox.Text = row.Cells[0].Value.ToString();
            mySecondTextBox.Text = row.Cells[1].Value.ToString();
            }
        }
    }

您可能希望将DataGridView.SelectionMode设置为DataGridViewSelectionMode.FullRowSelect

You may want to set the DataGridView.SelectionMode to DataGridViewSelectionMode.FullRowSelect

尝试

private void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e)
        {
           
                textbox1.Text = dataGridView1.Rows[e.RowIndex].Cells["Column1"].Value.ToString();
                textbox2.Text =    dataGridView1.Rows[e.RowIndex].Cells["Column2"].Value.ToString();

          
            
        }
