<RowStyle CssClass="itemstyle" /> 
<HeaderStyle CssClass="headerstyle" /> 
<AlternatingRowStyle CssClass="altstyle" />  
<Columns> 
    <asp:BoundField DataField="Description" HeaderText="Description" ReadOnly="True" SortExpression="Description"> 
     <ItemStyle Wrap="False" /> 
    </asp:BoundField> 
    <asp:BoundField DataField="Identifier" HeaderText="Identifier" ReadOnly="True" SortExpression="Identifier"> 
     <ItemStyle Wrap="False" /> 
    </asp:BoundField> 
    <asp:BoundField DataField="State" HeaderText="State" ReadOnly="True" SortExpression="State"> 
     <ItemStyle Wrap="False" /> 
    </asp:BoundField> 
    <asp:BoundField DataField="HostHeaderValue" HeaderText="Host Header Value" ReadOnly="True" 
     SortExpression="HostHeaderValue" /> 
    <asp:BoundField DataField="IPAddress" HeaderText="IP Address" ReadOnly="True" SortExpression="IPAddress" /> 
    <asp:BoundField DataField="Port" HeaderText="Port" ReadOnly="True" SortExpression="Port" /> 
    <asp:BoundField DataField="SSLPort" HeaderText="SSL Port" ReadOnly="True" SortExpression="SSLPort" />

按钮的状态设置

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
    { 
     try 
     { 
      if (e.Row.RowType == DataControlRowType.DataRow) 
      { 
       DataRowView entry = e.Row.DataItem as DataRowView; 
       if (entry != null) 
       { 
        switch (entry["State"] as string) 
        { 
         case "Stopped": 
          e.Row.Cells[2].BackColor = System.Drawing.Color.OrangeRed; 
          e.Row.Cells[2].ForeColor = System.Drawing.Color.White; 
          ((Button)e.Row.Cells[7].Controls[1]).Text = "Start"; 
          ((Button)e.Row.Cells[7].Controls[1]).ForeColor = System.Drawing.Color.Green; 
          ((Button)e.Row.Cells[7].Controls[1]).CommandArgument = entry["Site"] as string + "|" + entry["Description"] as string; 
          break; 
         case "Running": 
          e.Row.Cells[2].BackColor = System.Drawing.Color.Honeydew; 
          ((Button)e.Row.Cells[7].Controls[1]).Text = "Stop"; 
          ((Button)e.Row.Cells[7].Controls[1]).ForeColor = System.Drawing.Color.Red; 
          ((Button)e.Row.Cells[7].Controls[1]).CommandArgument = entry["Site"] as string + "|" + entry["Description"] as string; 
          break; 
         default: 
          e.Row.Cells[2].BackColor = System.Drawing.Color.Yellow; 
          e.Row.Cells[7].Text = ""; 
          break; 
        }
