        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;
                        }
                    };
                }
            }
        }

I want to change the back color of gridView1 rows that do not match the condition so i can verified them
Unfortunately, all rows become red.
how can I fix this problem.
Thanks in advance

Answer 1

Here code modified, it is done with notepad and it remains the test.

First the background color of gridview1 that must be changed according to the values of "BS" and "repère", this is done in the RowStyle function.

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;    
}

Adding gridview1 Rows to 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();
}
