Question

我正在使用两种形式，当我将StockID从一种形式发送到另一种形式时，在第二种形式中，gridview中有一些数据，现在我想做的就是，通过使用我要突出显示的id那行只。我想比较网格视图中是否存在ID，如果退出，我想要为该完整行做高位。，

if (pc == c)
{
    for (int i = 0; i < grid_stock.Rows.Count; i++)
    {
        grid_stock.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
        this.grid_stock.Rows[i].DefaultCellStyle.BackColor = Color.Red;
        break;
    }                       
}

Answer 1

试试这个，

在StockID

中提供row.Cells[0]的正确列索引

foreach (DataGridViewRow row in grid_stock.Rows) 
{
  if (row.Cells[0].Value.Equals("StockID")) 
  {
    grid_stock.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
    row.DefaultCellStyle.BackColor = Color.Red; 
  }
}

Answer 2

如果顶部的if条件是为了检查ID是否匹配，请将其置于for循环中，如下所示：

for (int i = 0; i < grid_stock.Rows.Count; i++)
{
    if(grid_stock.Rows[i].Cells[stockID_column_index].Value == received_stockID) // Check if the row IDs match here
    {
        grid_stock.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
        this.grid_stock.Rows[i].DefaultCellStyle.BackColor = Color.Red;
        break;
    }
}

将stockID_column_index替换为存储StockID的列的索引。

Answer 3

// on load or when refersh data

if (SelectingID != null)
{
    for (int i = 0; i < dgvInvoiceList.Rows.Count; i++)
    {
        BillingGeneral.InvoicesDataSet.InvoiceListRow dr = (BillingGeneral.InvoicesDataSet.InvoiceListRow)((DataRowView)dgvInvoiceList.Rows[i].DataBoundItem).Row;
        if (dr.ID == SelectingID.Value)
        {
            dgvInvoiceList.ClearSelection();
            dgvInvoiceList.Rows[i].Selected = true;
            SelectingID = null;
            break;
        }
    }
}

如何为gridview中的特定行执行颜色？
