Question

i am going to bind a datatable to the datagrid
i just want to change the color of a particular row of datagrid based on the value on datatable row. i need c#/.net code for it

Answer 1

Something like:

this.dataGridView1.Rows[RowIndex].DefaultCellStyle.BackColor = Color.Yellow;

Or if you want to it over a mouse move event

private void DataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e)
{
dataGridView1[e.ColumnIndex, e.RowIndex].Style.SelectionBackColor = Color.Red;
}

private void DataGridView_CellLeave1(object sender, DataGridViewCellEventArgs e)
{
dataGridView1[e.ColumnIndex, e.RowIndex].Style.SelectionBackColor = Color.Blue;
}

Also, Change individual DataGridView row colors based on column value might help.
