CellContentClick事件并不总是有效 [英] CellContentClick event doesn't always work

问题描述

CellContentClick 事件并不总是有效-它有时有效，有时不是随机产生的.

CellContentClick event doesn't always work - it sometimes works and sometimes not, randomly.

我的代码在下面，我正在使用断点进行检查，但是程序有时会进入该块，有时却不会.为什么会这样?

My code is below, I am checking by using breakpoints but program sometimes enters the block and and some times not. Why is it so?

private void dataGridView1_CellContentClick_1(object sender, DataGridViewCellEventArgs e)
{
    textBoxUserName.ReadOnly = true;
    button2.Visible = true;
    int index = e.RowIndex;
    if (!(index < 0))
    {
        DataGridViewRow row = dataGridView1.Rows[index];
        textBoxUserName.Text = row.Cells["UserNAme"].Value.ToString();
        textBoxPassword.Text = row.Cells["Pass"].Value.ToString();
        dataGridView1.Focus();
    }
    dataGridView1.Focus();
}

推荐答案

尝试使用

在单元格的任何部分被单击时发生.

Occurs when any part of a cell is clicked.

CellContentClick 单击单元格时不一定会触发事件，用户必须单击单元格的内容"区域，例如文本，例如:

The CellContentClick event won't necessarily fire when you click in the cell, the user has to click into the "content" area of the cell, like the text, for instance:

在单击单元格中的内容时发生.

Occurs when the content within a cell is clicked.
