这里我有两个表单（Form1和Cinvo），每个表单都有一个datagridview，我想将所有行从Form1 datagridview复制到Cinvo datagridview，我已经做了一些编码，它只从Form1 datagridview复制到Cinvo datagridview 。但是我想要复制所有行，所以如果有人可以做一些修改来获得我想要的结果。
Form1中
public partial class Form1 : Form
{
double total = 0;
public Form1()
{
InitializeComponent();
}
private void label2_Click(object sender, EventArgs e)
{
}
string st1;
string st2;
string st3;
string st4;
string st5;
string st6;
private void button1_Click(object sender, EventArgs e)
{
if (textBox6.Text == null && comboBox1.Text == null)
{
dataGridView1.Enabled = false;
}
else
{
st1 = textBox6.Text;
st2 = comboBox1.Text;
st3 = comboBox2.Text;
st4 = textBox7.Text;
st5 = textBox8.Text;
double x = float.Parse(textBox7.Text);
double y = float.Parse(textBox8.Text);
double p = x * y;
total = total + p;
textBox9.Text = total.ToString ();
st6 = Convert.ToString(p);
string[] row = { st1, st2, st3, st4, st5, st6};
dataGridView1.Rows.Add(row[0], row[1], row[2], row[3], row[4],row[5]);
}
textBox6.Text = null;
textBox7.Text = null;
textBox8.Text = null;
comboBox1.Text = null;
comboBox2.Text = null;
//double g = float.Parse(textBox7.Text);
//double h = float.Parse(textBox8.Text);
//double gh = g * g;
//double total = 0;
//total = total + gh;
//textBox9.Text = Convert.ToString(total);
}
private void button2_Click(object sender, EventArgs e)
{
textBox1.Text = null;
textBox2.Text = null;
comboBox3.Text = null;
comboBox4.Text = null;
textBox6.Text = null;
textBox7.Text = null;
textBox8.Text = null;
textBox9.Text = null;
// dataGridView1.Rows.Clear();
}
private void button3_Click(object sender, EventArgs e)
{
if (comboBox3.Text ==""|| textBox2.Text == ""|| comboBox4.Text =="")
{
MessageBox.Show("Sorry, Customer is not registered");
}
else
{
MessageBox.Show("asc");
}
}
private void button6_Click(object sender, EventArgs e)
{
// float x=(dataGridView1.Rows[i].Cells[4].ToString());
}
private void button4_Click(object sender, EventArgs e)
{
string a1 = null;
string a2 = null;
string a3 = null;
string a4 = null;
string a5 = null;
string a6 = null;
for(int i =0; i<dataGridView1.RowCount;i++)
{
a1 = dataGridView1.Rows[i].Cells[0].Value.ToString();
a2 = dataGridView1.Rows[i].Cells[1].Value.ToString();

a4 = dataGridView1.Rows[i].Cells[3].Value.ToString();
a5 = dataGridView1.Rows[i].Cells[4].Value.ToString();
a6 = dataGridView1.Rows[i].Cells[5].Value.ToString();
}
Cinvo ops = new Cinvo(a1, a2, a3, a4, a5,a6);
// Cinvo nwcn = new Cinvo();
ops. ShowDialog();
}
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
}
private void button7_Click(object sender, EventArgs e)
{
try
{
dataGridView1.Rows.RemoveAt(dataGridView1.CurrentCell.RowIndex);
}
catch ( Exception ex)
{
}
}
private void button5_Click(object sender, EventArgs e)
{
int i = dataGridView1.CurrentRow.Index;
DataGridViewRow row = dataGridView1.Rows[i];
row.Cells[0].Value = textBox6.Text;
row.Cells[1].Value = comboBox1.Text;
row.Cells[2].Value = comboBox2.Text;
row.Cells[3].Value = textBox7.Text;
row.Cells[4].Value = textBox8.Text;
}
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
int i = e.RowIndex;
DataGridViewRow row = dataGridView1.Rows[i];

textBox8.Text = row.Cells[4].Value.ToString();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void groupBox2_Enter(object sender, EventArgs e)
{
}
Cinvo
public partial class Cinvo : Form
{
private string a1;
private string a2;
private string a3;
private string a4;
private string a5;
private string a6;
//public Cinvo()
//{
// InitializeComponent();
// //Form1 frm1 = new Form1();
//}
public Cinvo(string a1, string a2, string a3, string a4, string a5, string a6)
{
InitializeComponent();
// TODO: Complete member initialization
this.a1 = a1;
this.a2 = a2;
this.a3 = a3;
this.a4 = a4;
this.a5 = a5;
this.a6 = a6;
string[] row = { a1, a2, a3, a4, a5, a6 };
dataGridView1.Rows.Add(row[0], row[1], row[2], row[3], row[4], row[5]);
}
private void tableLayoutPanel1_Paint(object sender, PaintEventArgs e)
{
}
private void Cinvo_Load(object sender, EventArgs e)
{
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
float x = float.Parse(textBox3.Text);
float y = float.Parse(textBox1.Text);
float z = y - x;
string final = Convert.ToString(z);
textBox2.Text = final;
}
答案 0 :(得分：0)
这样的事情对你有用吗？
CopyDataGridViews(dataGridView1, dataGridView2);
功能：
public void CopyDataGridViews(DataGridView SourceDGV, DataGridView DestinationDGV)
{
// Clear Destination DataGridView
DestinationDGV.Columns.Clear();
DestinationDGV.Rows.Clear();
// Create Destination Columns
for (int j = 0; j < SourceDGV.Columns.Count; j++)
{
DestinationDGV.Columns.Add(SourceDGV.Columns[j].Clone() as DataGridViewColumn);
}
// Create Destination Rows
for (int i = 0; i < SourceDGV.Rows.Count - 1; i++)
{
DestinationDGV.Rows.Add(SourceDGV.Rows[i].Clone() as DataGridViewRow);
}
// Copy Data to Destination
for (int column = 0; column < SourceDGV.Columns.Count; column++)
{
for (int row = 0; row < SourceDGV.Rows.Count; row++)
{
DestinationDGV.Rows[row].Cells[column].Value = SourceDGV.Rows[row].Cells[column].Value;
}
}
}
