how i can disable and enabled based on a single dataGridview cell color

u can disable and enable a button in girdview in rowbound event

1. protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
2. {
3.      if (e.Row.RowType == DataControlRowType.DataRow)
4.      {
5.          //u can check your addition condition here for color of cell or any thing else
6.              e.Row.Cells[3].FindControls["timein"].Enabled = flase;
7.       }
8.      }
9. }

I am going with windows forms datagridview, since your question states datagridview and you question is posted under C#.Net category.
Check the below single line of code, I am not sure why you were using the SelectedCells and your requirement was nothing to do with the selected cells.

time_in.Enabled = (dataGridView1.Rows[0].Cells[0].Style.ForeColor == Color.Red);

   hello Guy's i try all suggestions still all the codes are not work. to make my Q clear .........
 
   i use two buttons  out side of the dataGridview  to change the color of each cell in the dataGridview from red to green and Green to red to do this

private void time_in_Click(object sender, EventArgs e)
        {
            employee_InformationDataGridView.SelectedCells[0].Style.ForeColor = Color.Green;
   
        }
private void time_out_Click(object sender, EventArgs e)
        {
            employee_InformationDataGridView.SelectedCells[0].Style.ForeColor = Color.Red;
            }
now i want to enable and disable my two Button based on the color and for each selected cell i mean when the text is red in the dataGridview time_in button only enable if it is green button time_out  is only enable. 

Here is the code

i try this code also it is not working for the first cells only. it is not work as i want it.
