Hi.. friends a window based project is being developed by me, I am getting the record of students from SQL database and show in Datagridview. The students are divided in different - 2 category for example Commerce, Medical and Arts.The problem is that if the student is in Commerce category then I want to show a red color circle in a Datagridview column in front of associated student record, if he is in Medical category then yellow color circle and if in Arts then green color circle, I add the column at design time and take an image type column to show circle and place an image of circle in it, but how can I change the color of this image according to my conditions.

Please help me I need it very urgent if anybody have some idea about it.

Thanks & Regards

Itz pretty simple. Sample code is:

C#

private void myDataGridView_CellValueChanged(object sender, DataGridViewCellEventArgs e)
  {
   int colIndex = e.ColumnIndex;
   int rowIndex = e.RowIndex;

   if (rowIndex >= 0 && colIndex >= 0)
   {
    DataGridViewRow theRow = dataGridView1.Rows[rowIndex];
    if (theRow.Cells[colIndex].Value.ToString() == "Commerce")
     theRow.DefaultCellStyle.BackColor = Color.Red;
    elseif (theRow.Cells[colIndex].Value.ToString() == "Medical")
     theRow.DefaultCellStyle.BackColor = Color.Yellow;
    if (theRow.Cells[colIndex].Value.ToString() == "Arts")
     theRow.DefaultCellStyle.BackColor = Color.Green;
   }
  }
