I have a win form that has a gridview, and I need to change the color of the cell, based on itslef and a different cell.
If you look at the code below it works fine when changign the color of the cell besad on the current cells value.
But I need to be able to compare both values and then change the cell color.

The position of the colums can change but not the name.

        private void ECCN_CellFormatting(DataGridViewCellFormattingEventArgs ee, string case_str)
        {

            switch (case_str)
            {
                case "Y": ee.CellStyle.BackColor = Color.LawnGreen; break;
                case "N": ee.CellStyle.BackColor = Color.Red; break;
                case "0": ee.CellStyle.BackColor = Color.Red; ee.CellStyle.ForeColor = Color.Yellow; break;
                default: break;
            }
        }

        private void dataGridView_CellFormatting(object sender, DataGridViewCellFormattingEventArgs ee)
        {

            switch (dataGridView1.Columns[ee.ColumnIndex].Name)
            {
                case "eccn_available": ECCN_CellFormatting(ee, (string)ee.Value); break;
                case "eccn_value": ECCN_CellFormatting(ee, (string)ee.Value); break;
                default: break;
            }
        }


these methods are called by :
        public void InitializeGrid(DataGridView lv_StockCheckdataGridView
                                  ,string GridViewName)
        {

 
            lv_StockCheckdataGridView.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
            lv_StockCheckdataGridView.ContextMenuStrip = this.contextMenuStrip1;
            lv_StockCheckdataGridView.AllowUserToAddRows = false;
            lv_StockCheckdataGridView.AllowUserToDeleteRows = false;
            lv_StockCheckdataGridView.AllowUserToOrderColumns = true;
            lv_StockCheckdataGridView.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom)
                        | System.Windows.Forms.AnchorStyles.Left)
                        | System.Windows.Forms.AnchorStyles.Right)));
            lv_StockCheckdataGridView.Size = new System.Drawing.Size(1074, 604);
            lv_StockCheckdataGridView.TabIndex = 5;
            lv_StockCheckdataGridView.MouseDown += new System.Windows.Forms.MouseEventHandler(this.dataGridView1_MouseDown);
            lv_StockCheckdataGridView.CellFormatting += new System.Windows.Forms.DataGridViewCellFormattingEventHandler(this.dataGridView_CellFormatting);
            lv_StockCheckdataGridView.Location = new System.Drawing.Point(12, 43);
            lv_StockCheckdataGridView.Name = GridViewName;
            lv_StockCheckdataGridView.ReadOnly = true;
            lv_StockCheckdataGridView.AllowUserToResizeColumns = true;

        }


I need a way to look at all the values for the rows I have just populated in the grid and

Hi,

Each row in the grid has cells to hold the data. So u can verify the cells in the row which u want before calling the actual Formatting as shown below.

Here i am checking the values in the current cell with the first cell in my row when they are equal then i call the method in the switch.

 private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs ee)
{
if (ee.RowIndex > -1)
{
                DataGridViewRow row = dataGridView1.Rows[ee.RowIndex];

                switch (dataGridView1.Columns[ee.ColumnIndex].Name)
                {
                    case "eccn_available":

                        if (Convert.ToString(ee.Value).Equals(Convert.ToString(row.Cells[0].Value)))
                        {
                            ECCN_CellFormatting(ee, (string)ee.Value);
                        }
                        break;
                    case "eccn_value":
                        ECCN_CellFormatting(ee, (string)ee.Value);
                        break;
                    default: break;
                }
            }
}

I have been pulled away from this project at the moment, so I can confirm the result from the solution, but I am going to give you the points and assume for now that the solution works, thanks Jay
