</tr>
</ContentTemplate>
</asp:UpdatePanel>

protected void ddlIllCategory_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlIllCategory.SelectedIndex != 0)
{
if (ddlPG.SelectedIndex != 0 && ddlCustomer.SelectedIndex != 0)
{
this.trApprove1.Visible = true;
this.trApprove2.Visible = true;
this.trApprove3.Visible = true;
this.tdApprover.RowSpan = 6;
}

}

}

這是table里的一段代碼，SelectedIndexChanged启动的时候，只刷新ContentTemplate的东西
我的上述代码这样写，还是全部刷新了，急求原因及答案！！
