 }

按钮1

   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;
    }

如果我点击button1，它是正确的，但当我点击button2时，button1会接到电话！

Answer 1

如果我理解正确，你会在if语句中遇到问题。

如果button1上的文字为1，则会执行您的if语句，无论点击哪个按钮，该文本都会保持为真。

要解决此问题，请使用整数变量并在button1_Click和button2_Click事件中保存其中的不同值，并在if语句中使用这些值，而不是按钮上的文本。 / p>

这可以是示例代码：

按钮点击事件：

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;
}

if语句：

        if (button1.text == "1" && code == 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" && code == 2)//another 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();
            textBox9.Text = dataGridView1.Rows[i].Cells[2].Value.ToString();
       }

Answer 2

因为buttn1仍然有TEXT==1而且我不知道buttn2下的代码是什么..！

你操了吗？

Answer 3

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;


         Button1Click = true;
    }
    bool Button1Click = false;
    bool Button2Click = false;
    private void button2_Click(object sender, EventArgs e)
    {
        /////another category
         Button2Click = true;

    }

    private void dataGridView_CellClick(object sender, DataGridViewCellEventArgs e)
    {
        if (button1.text == "1" && Button1Click)//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" && Button2Click)//another 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();
            textBox9.Text = dataGridView1.Rows[i].Cells[2].Value.ToString();

        }
    }

我只是简单地控制你的方法点击EventHandler。

按钮到Datagridview到文本框
