我有两个网格视图和一个按钮单击按钮我将数据从 gridView1 复制到 gridView2 这是我的代码： 

private async void btnAdd_Click(object sender, EventArgs e)
    {
        int[] selectedRows = gridView1.GetSelectedRows();
        for (int i = 0; i < selectedRows.Length; i++)

        {
            DataRow rowGridView1 = (gridView1.GetRow(selectedRows[i]) as DataRowView).Row;
            for (int j = 0; j < gridView3.RowCount; j++)
            {
                if (rowGridView1["BS"].ToString() == gridView3.GetRowCellValue(j, "ProjectN").ToString() &&
                    rowGridView1["Repère"].ToString() == gridView3.GetRowCellValue(j, "Parts").ToString())
                {
                    DataRow row = dt.NewRow();
                    row[0] = rowGridView1["BS"];
                    row[1] = gridView3.GetRowCellValue(j, "Parts");
                    row[2] = gridView3.GetRowCellValue(j, "Profile");
                    row[3] = rowGridView1["Quantité"];

                    dt.Rows.Add(row);
                }
                else if(j == (gridView3.RowCount -1)) 
                {
                    gridView1.RowStyle += (senderr, ee) => {

                        if (gridView1.GetFocusedDataRow() == rowGridView1)
                        {
                            ee.Appearance.BackColor = Color.Red;
                            ee.HighPriority = true;
                        }
                    };
                }
            }
        }

我想更改与条件不匹配的 gridView1 行的背景颜色，以便我可以验证它们
不幸的是，所有行都变为红色。
我该如何解决这个问题。
提前致谢

这里代码修改，它是用记事本完成的，它仍然是测试。

首先gridview1的背景颜色必须根据“BS”和“repère”的值改变，这是在RowStyle函数中完成的。

private void gridView1_RowStyle(object sender, RowStyleEventArgs e)  {  

    If (e.RowHandle = this.gridView1.FocusedRowHandle)  
    {
       string strBS = gridView1.GetRowCellValue(row, "BS");
       string strRepere = gridView1.GetRowCellValue(row, "Repère");
        if (SearchRow(strBS,strRepere)==true)
         {
           e.Appearance.BackColor = Color.Red  
           e.HighPriority = True  
          }
    }
}

private bool SearchRow(string strBS, string strRepere)  {  
    bool RowExist=false;
    for (int j = 0; j < gridView3.RowCount; j++)
    {
      if (gridView3.GetRowCellValue(j, "ProjectN").ToString() ==strBS &&
        gridView3.GetRowCellValue(j, "Parts").ToString()==strRepere)
      {
         RowExist=true;
         Break;
      }
    }
   return RowExist;    
}

将 gridview1 行添加到 gridview3

private async void btnAdd_Click(object sender, EventArgs e)
{
        int[] selectedRows = gridView1.GetSelectedRows();
        for (int i = 0; i < selectedRows.Length; i++)
        {
            DataRow rowGridView1 = (gridView1.GetRow(selectedRows[i]) as DataRowView).Row;
            for (int j = 0; j < gridView3.RowCount; j++)
            {
                if (rowGridView1["BS"].ToString() == gridView3.GetRowCellValue(j, "ProjectN").ToString() &&
                    rowGridView1["Repère"].ToString() == gridView3.GetRowCellValue(j, "Parts").ToString())
                {
                    DataRow row = dt.NewRow();
                    row[0] = rowGridView1["BS"];
                    row[1] = gridView3.GetRowCellValue(j, "Parts");
                    row[2] = gridView3.GetRowCellValue(j, "Profile");
                    row[3] = rowGridView1["Quantité"];

                    dt.Rows.Add(row);
            dt.AcceptChanges();
                }
            }
       }

       gridView1.Datasource=dt;
       grid.DataBind();
}
