如何更改gridview行颜色？

Question

我有我的代码来更改 GridView 背景颜色中的行 状态完成。我很好地完成了我的代码，但它不起作用。

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; }

}

我是在网格的rowdatabound事件上做的

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;
    }
}
