C# Datagridview到文本框的按钮

按钮1

private void dataGridView_CellClick(object sender, DataGridViewCellEventArgs e)

    {
        if (button1.text == "1")//its a category
        {
            int i;
            i = dataGridView1.SelectedCells[0].RowIndex;
            textBox7.Text = dataGridView1.Rows[i].Cells[0].Value.ToString();
            textBox6.Text = dataGridView1.Rows[i].Cells[1].Value.ToString();
            textBox2.Text = dataGridView1.Rows[i].Cells[3].Value.ToString();
            textBox5.Text = dataGridView1.Rows[i].Cells[4].Value.ToString();
            textBox3.Text = dataGridView1.Rows[i].Cells[5].Value.ToString();
            textBox8.Text = dataGridView1.Rows[i].Cells[6].Value.ToString();
            textBox9.Text = dataGridView1.Rows[i].Cells[2].Value.ToString();
        }
        if (button2.text == "2")//another category

如果我点击按钮1，它是对的，但是当我点击按钮2，按钮1得到呼叫

原因

buttn1

仍然有

TEXT==1

，我不知道您的代码在

buttn2

下是什么

你处理好了吗？

如果我理解正确，你的If语句有问题

如果

button1

上的文本为

1

，则执行if语句，无论单击哪个按钮，该语句都保持为true

要解决此问题，请使用整数变量并将不同的值保存在

按钮1\u单击

和

按钮2\u单击

事件中，并在if语句中使用这些值，而不是按钮上的文本

这可以是示例代码：

按钮单击事件：

   private void button1_Click(object sender, EventArgs e)

    {
        SqlDataAdapter sda = new SqlDataAdapter(@"Select * from Accessories", con);
        DataTable dt = new DataTable ();
        sda.Fill(dt);
        dataGridView1.DataSource = dt;
    }

国际单项体育联合会声明：

int code = 1;
private void button1_Click(object sender, EventArgs e)
{
    //your code
    code = 1;
}
private void button1_Click(object sender, EventArgs e)
{
    //your code
    code = 2;
}

我只是做了一个简单的方法来控制你的点击事件处理程序。

显示按钮的代码。我在按钮2中的代码与按钮1相同，但“附件”是“其他”它现在必须工作：）字符串x=button1_Click（）；？我怎么能做到呢？我不明白你到底想做什么，因为方法不能存储在字符串变量中！那么，你能解释一下你到底想在语句中做什么吗，string x=button1_Click（）；，所以我可以帮你吗？什么都没有发生，它只是禁用了cellclickits现在必须工作：）错误，我想，这是因为按钮1有7列，按钮2有6列。我不知道你的错误，但我认为类别first中的第一个数据表的列数比另一个类别中的数据表的列数多或少，所以请检查这些类别并确保数据表的列数和索引数相同。
