按鈕的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; 
    } 

如果我點擊Button1的，它是正確的，但是當我點擊按鈕2，按鈕1獲得來電！

Answer 1

如果我理解正確，那麼if語句中存在問題。

如果button1上的文本是1，並且無論點擊哪個按鈕，該if語句都會被執行。

要解決此問題，請使用整數變量並將其中的不同值保存在button1_Click和button2_Click事件中，並在if語句中使用這些值而不是按鈕上的文本。

這可以是樣本代碼：

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; 
} 

的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

原因buttn1仍然有TEXT==1，我不知道buttn2下你的代碼是什麼..！

你有沒有處理它？

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(); 

     } 
    } 

我只是沒有簡單的方法來控制UR點擊事件處理。
