[英]Add Columns to DataGridView
我用屬性填充列表,並且希望該列表成為dataGridviiew的數據源。
但是,當我將此列表設置為dataGridView作為dataSource時,所有屬性值都位於一列中。 如何在dataGridView中為每個屬性添加一列?
這是我的代碼:
private void dataGridView2_CellClick(object sender, DataGridViewCellEventArgs e)
{
Restaurant n = new Restaurant );
foreach (DataGridViewCell cell in dataGridView2.SelectedCells)
{
IList<String> lista = new List<String>();
n.Data = string.Empty;
n.Data2 = string.Empty;
int indexOfYourColumn = 9;
int index2 = 0;
foreach (DataGridViewRow row in dataGridView1.Rows)
{
n.Data = row.Cells[indexOfYourColumn].Value.ToString();
n.Data2 = row.Cells[index2].Value.ToString();
if (cell.Value.ToString() == n.Data.ToString())
{
lista.Add(n.Data);
lista.Add(n.Data2);
dataGridView3.DataSource = lista.Select(x => new { Value = x }).ToList();
}
}
}
}
我認為您正在嘗試執行類似的操作,盡管我不確定,因為您的代碼尚不清楚。
private void dataGridView2_CellClick(object sender, DataGridViewCellEventArgs e)
{
/* Place indexes here, there is no need to initialize *
* so many integers inside loop if they're not changing */
int indexOfYourColumn = 9, index2 = 0;
var restaurantList = new List<Restaurant>();
foreach (DataGridViewCell cell in dataGridView2.SelectedCells)
{
foreach (DataGridViewRow row in dataGridView1.Rows)
{
if (cell.Value.ToString() == row.Cells[indexOfYourColumn].Value.ToString())
{
restaurantList.Add(new Restaurant()
{
Data = row.Cells[indexOfYourColumn].Value.ToString(),
Data2 = row.Cells[index2].Value.ToString()
});
}
}
}
dataGridView3.DataSource = restaurantList;
}
