Looping each row in datagridview
提问by Ke Vin
How to loop each row that readed? in my code, the row won't bind to next row because of the same productID, so the datagridview won't move to new row, it still in the same row and overwrite the price (for some product, i have two price). How to loop it to show the same productID but it have different price.
如何循环读取的每一行？在我的代码中，由于相同的 productID，该行不会绑定到下一行，因此 datagridview 不会移动到新行，它仍然在同一行并覆盖价格（对于某些产品，我有两个价格） . 如何循环它以显示相同的 productID 但它有不同的价格。
EX : 1 Hamburger have 2 price Hamburger : $1 and $2 when i get the data with looping it, the resould shoult be have 2 Row with same product but different price. How to do this? below is my code
例如：1 个汉堡包有 2 个价格汉堡包：1 美元和 2 美元，当我通过循环获取数据时，结果应该是 2 行，产品相同但价格不同。这该怎么做？下面是我的代码
productID = odr["product_id"].ToString();
quantity = Double.Parse(odr["quantity"].ToString());
//processing data...
key = productID.ToString();
if (key != key_tmp)
{
//update index...
i++;
//updating variable(s)...
key_tmp = key;
}
if (datagridviews.Rows[i].Cells["qty"].Value != null) //already has value...
{
currJlh = Double.Parse(ddatagridviews.Rows[i].Cells["qty"].Value.ToString());
}
else //not yet has value...
{
currQty = 0;
}
currQty += qty;
//show data...
datagridviews.Rows[i].Cells["price"].Value = cv.toAccountingCurrency_en(Double.Parse(odr["item_price"].ToString()));
MessageBoxes.Show(i.ToString());
MessageBoxes.Show(datagridviews.Rows[i].Cells["price"].Value.ToString()); // in here there is two price that looped but won't showed in datagridviews
help me out :)

You could loop through DataGridViewusing Rowsproperty, like:
您可以循环DataGridView使用Rows属性，例如：
foreach (DataGridViewRow row in datagridviews.Rows)
{
currQty += row.Cells["qty"].Value;
//More code here
}

Best aproach for me was:
对我来说最好的方法是：
private void grid_receptie_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
int X = 1;
foreach(DataGridViewRow row in grid_receptie.Rows)
{
row.Cells["NR_CRT"].Value = X;
X++;
}
}
