按鈕到Datagridview到文本框

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();
       }
 }

按鈕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;
    }

如果我單擊button1，那是正確的，但是當我單擊button2時，button1會接到電話！

Answer 1

如果我正確理解，則if語句中有問題。

如果button1上的文本為1 ，則將執行if語句，無論單擊哪個按鈕，它都保持為true。

要解決此問題，請使用整數變量，並將不同的值保存在button1_Click和button2_Click事件中，並在if語句而不是按鈕上的文本中使用這些值。

這可以是示例代碼：

按鈕單擊事件：

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語句：

        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

因為buttn1仍然具有TEXT==1 ，所以我不知道您在buttn2下的代碼是buttn2 。

你處理好了嗎？

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();

        }
    }

我只是做了簡單的方法來控制您的Click EventHandler。
