如何更改gridview行的顏色？

Question

當狀態為“完成”時，我有代碼來更改GridView背景色中的行。 我的代碼做得很好，但是沒有用。

protected void status_SelectedIndexChanged(object sender, EventArgs e)
{
    DropDownList ddlStatus = (DropDownList)sender;


    string someVariable1 = ddlStatus.SelectedItem.Text; // gets the Text displayed
    string someVariable2 = ddlStatus.SelectedItem.Value; // gets the Value 

    GridViewRow row = (GridViewRow)ddlStatus.NamingContainer;


    if (someVariable1 == "Done")
    { row.BackColor = System.Drawing.Color.Red; }

}

我在網格的rowdatabound事件上執行此操作

protected void Grid_RowDataBound(Object sender, GridViewRowEventArgs e) {
    string someVariable1 = Convert.ToString((Grid.Rows[0].Cells["comboCell"] as DataGridViewComboBoxCell).FormattedValue.ToString());

    if(e.Row.RowType == DataControlRowType.DataRow) {
         if(someVariable1 == "Done")
             e.Row.BackColor = Color.Green;
    }
}
