You can achieve this in windows form by:

Attach to the event

this.dataGridView1.RowPrePaint += new System.Windows.Forms.DataGridViewRowPrePaintEventHandler( this.dataGridView1_RowPrePaint);

The event code

private void dataGridView1_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e)

// your condition here

if (Convert.ToInt32(dataGridView1.Rows[e.RowIndex].Cells[7].Text) < Convert.ToInt32(dataGridView1.Rows[e.RowIndex]..Cells[10].Text))

        dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Beige;

Do let me know if it solves your problem

Hi.Please write your code like this.
protected void gvStudentGrade_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
bool getValue = e.Row.Cells[2];
string setColorClass=string.Empty;
if (getValue) {
setColorClass = "green"; // setting green color class
}
else {
setColorClass = "red";
}
e.Row.CssClass = setColorClass;
}
}
thanks

Add following code in *.aspx page:
<asp:GridView ID="TaskNameGrid"
    runat="server"
    AllowPaging="True"
    AutoGenerateColumns="False"
    CssClass="SearchResultsTable"
    virtualitemcount1="-1"
    Width="400px" DataSourceID="ObjectDataSource1"
    onrowdatabound="Update_RowDataBound">

    <AlternatingRowStyle CssClass="alternate" />
    <Columns>
    <asp:BoundField DataField="BusinessIdentifier" HeaderText="BusinessIdentifier"
    SortExpression="BusinessIdentifier" />
    <asp:BoundField DataField="SLA" HeaderText="SLA" SortExpression="SLA" />
    Columns>
    <HeaderStyle ForeColor="White" />
    <RowStyle />

asp:GridView>
Next add following code in Code-behind(*.aspx.cs) file:
protected void Update_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // Getting value from gridview row cell
        int quantity = int.Parse(e.Row.Cells[1].Text);

        // Logic to change color dynamically
        if (quantity > 100)
        {
            e.Row.BackColor = System.Drawing.Color.Red;
        }
        else
        {
            e.Row.BackColor = System.Drawing.Color.Green;
        }
    }
}
