Question

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
        {
            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();
       }
 }

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，是正确的，但是当我点击button2时，button1接到电话！

Answer 1

因为 buttn1 仍然有 TEXT==1 我不知道你的代码在 buttn2..!

你处理了吗？

Answer 2

如果我没理解错的话，你的 if 语句有问题。

如果 button1 上的文本是 1，则执行您的 if 语句，无论单击哪个按钮，它都保持为真。

为了解决这个问题，在 button1_Click 和 button2_Click 事件中使用整数变量并在其中保存不同的值，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 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();

        }
    }

我刚刚做了简单的方法来控制您的点击事件处理程序。
