推荐答案

尝试以下代码:

使用者介面:

Try this code:

UI:

<asp:LinkButton ID="LinkButton1" runat="server" Font-Bold="True"

       Font-Underline="False" onclick="LinkButton1_Click">one</asp:LinkButton><br />
   <asp:LinkButton ID="LinkButton2" runat="server" Font-Bold="True"

       Font-Underline="False" onclick="LinkButton2_Click">two</asp:LinkButton><br />
   <asp:LinkButton ID="LinkButton3" runat="server" Font-Bold="True"

       Font-Underline="False" onclick="LinkButton3_Click">three</asp:LinkButton><br />
   <asp:LinkButton ID="LinkButton4" runat="server" Font-Bold="True"

       Font-Underline="False" onclick="LinkButton4_Click">four</asp:LinkButton><br />

C#代码:

C# code:

protected void LinkButton1_Click(object sender, EventArgs e)
  {
      LinkButton1.Enabled = false;
      LinkButton2.Enabled = true;
      LinkButton3.Enabled = true;
      LinkButton4.Enabled = true;
      LinkButton1.BackColor = System.Drawing.Color.Gray;
  }
  protected void LinkButton2_Click(object sender, EventArgs e)
  {
      LinkButton2.Enabled = false;
      LinkButton1.Enabled = true;
      LinkButton3.Enabled = true;
      LinkButton4.Enabled = true;
      LinkButton2.BackColor = System.Drawing.Color.Gray;
  }
  protected void LinkButton3_Click(object sender, EventArgs e)
  {
      LinkButton3.Enabled = false;
      LinkButton1.Enabled = true;
      LinkButton2.Enabled = true;
      LinkButton4.Enabled = true;
      LinkButton3.BackColor = System.Drawing.Color.Gray;
  }
  protected void LinkButton4_Click(object sender, EventArgs e)
  {
      LinkButton4.Enabled = false;
      LinkButton1.Enabled = true;
      LinkButton3.Enabled = true;
      LinkButton2.Enabled = true;
      LinkButton1.BackColor = System.Drawing.Color.Gray;
  }
