How to traverse/loop through each cell of particular COLUMN of DevExpress.GridView.gridcontrol in C# WinForm Application..?

Question

I want to traverse through each cell of particular (Known) column of DevExpress.GridView.gridcontrol to put some validation depending on particular cell value, as of now what I have tried is as follows--

for (int i = 0; i < gridView1.Columns.Count; i++)
{
     this.gridView1.Columns[i].AppearanceCell.BackColor = Color.Red;
}

Using above code I can can loop through each column of DevExpress.GridView.gridcontrol but unable to loop through each cell of particular (i-th) column . Hope you understand what I'm trying to say. Please help.. Thanks in advance..!!

Answer 1

There are examples of that in the reference:

Validating rows

Conditional Style Formatting

GridView.RowStyle Event

GridView.RowCellStyle Event

And a simple loop:

// iterate cells and compose a tab delimited string of cell values
for (int i = 0; i < m_gridView.RowCount; i++)
{
     int rowHandle = m_gridView.GetRowHandle(i);
     ...
}
// and
for(int i = 0; i < gridView1.DataRowCount; i++)
{
     //Do something here
}

look also at: GridView.GetRowCellValue method

Answer 2

Finally I got the answer it is done by using RowCellStyle event as follows--

private void gridView1_RowCellStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e)
        {
            DevExpress.XtraGrid.Views.Grid.GridView View = sender as DevExpress.XtraGrid.Views.Grid.GridView;

            if (e.Column.FieldName == "XYZ")
            {               
                string strCellValue = View.GetRowCellDisplayText(e.RowHandle, View.Columns["XYZ"]);
                int inStockCol = e.RowHandle;
                if (!strCellValue.Equals("NA"))
                {
                    double dblCellValue = Convert.ToDouble(strCellValue);

                    if (dblCellValue < 0 || dblCellValue > 1000)
                    {
                        e.Appearance.BackColor = Color.Red;
                        e.Appearance.BackColor2 = Color.LightPink;                      

                    }
                    else
                    {
                        e.Appearance.BackColor = Color.Green;
                        e.Appearance.BackColor2 = Color.LightGreen;
                    }
                }

            }
}
