C＃更改DataGridView行的BackColor

Question

I have a Table From Database That holds Some informations about users i want when the Value of The User Cell[5] is "Connected" to change the backcolor of that row :

here is my function :

        public void Initialize(DataGridView Dt)
        {

            foreach(DataGridViewRow Row in Dt.Rows)
            {
                if (Row.Cells[5].Value.ToString() == "Connected")
                {

                    Row.DefaultCellStyle.BackColor = Color.Green;
                }

                else
                {
                    Row.DefaultCellStyle.BackColor = Color.Red;

                }
            }

        }

Everything work perfect no exceptions where thrown but My row color didnt change in both cases

Please Note That im using MetroGridView from Metro Dll

You have to handle cell formatting event to achieve your goal. Tried a sample code below. It is working.

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
        {
              if(dataGridView1.Columns[e.ColumnIndex].Name == "C")
              {
                  if(e.Value != null)
                  {
                      String StringValue =(String)e.Value;
                      if (StringValue.IndexOf("C1") > -1)
                      {

                          dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Red;
                      }
                  }

              }

        }

Mu guess is, even though you are doing it right, the cell formatting event which triggers at later part, is overriding your changes.
