ASP.NET如何在单击按钮+行条目时更改表行的背景颜色？

Question

I have a table with one row which is filled in with values after the user clicks a button. I want to change the background color of the row to different colors based on the values that are filled in to the row.

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Search" />
<tr>
    <td runat="server" id ="td1" class="auto-style1"></td>
    <td runat="server" id ="td2" class="auto-style1"></td>
    <td runat="server" id ="td3" class="auto-style1"></td>
    <td runat="server" id ="td4" class="auto-style1"></td>
</tr>

and my Button1_Click function looks like

protected void Button1_Click(object sender, EventArgs e)
{
    string[]toDisp = someFunction();
    td1.InnerText = toDisp[0];
    td2.InnerText = toDisp[1];
    td3.InnerText = toDisp[2];
    td4.InnerText = toDisp[3];
}

Basically, I want to set the background color of the table row based on the value of toDisp[1]. How should I go about doing this? Thanks.

If its going to be just 1 row

just set a ID to it with runat attribute

<tr id="test" runat="server">
    <td runat="server" id ="td1" class="auto-style1"></td>
    <td runat="server" id ="td2" class="auto-style1"></td>
    <td runat="server" id ="td3" class="auto-style1"></td>
    <td runat="server" id ="td4" class="auto-style1"></td>
</tr>

then based on the condition of toDisp[1]

you can write a switch statement or Random (based on color requirement) to just set

test.BgColor = "SomeColor";
