★コントロール注意点

<asp:Radiobutton ID="radioButton1" AutoPostBack="true" runat="server" Text="選択１" GroupName="Content" Checked="True" OnCheckedChanged="radioButton1_CheckedChanged">

Checkedを設定すると、画面初期時にOnCheckedChangedは発生できない。

★ポストバック後にスクロールの位置を保持

※スクロールをさせない方法がわからない、残念。

方法１（cs側）

Page.MaintainScrollPositionOnPostBack = true;

方法２（aspx側）

<%@ Page MaintainScrollPositionOnPostBack="true" ... %>

★<% %>について

１．コード

<%

Reaponse.Write("xxx");

%>

２．データバインド（DataBind()で実行）

<%# DataBinder.Eval(Container.DataItem, "ID").ToString()%>

<%# Container.DataItem("ID") %>

<%# hidden.Value%>

<%# Eval("Name") %> 読み取り専用

<%# Bind("Name") %> 更新可能

３．値表示

<%= Page.IsPostBack %>

*.aspx <%= name%>

*.cs public string name = "xxx";

４．名前空間など

<%@ Page %>

<%@ Assembly %>

<%@ Import %>

<%@ MasterType %>

<%@ OutputCache %>

<%@ PreviousPageType %>

<%@ Reference %>

<%@ Register %>

５．リソース

<asp:Label ID="lbl" runat="server" Text="<%$ Resources:TestSite, TotalAmount %>"></asp:Label>

６．ASP.NET MVCのViewData

<%: ViewData["Message"] %>

７．コメント

<%-- コメント --%> HTMLに出力しない

<!-- コメント --> HTMLに出力する

★OnClickとOnClientClick

OnClick Buttonのイベント（サーバ側）

OnClientClick Buttonの属性（クライアント側）

<asp:Button runat="server" ID="btn1" Text="テスト１" onclick="btn_Click" OnClientClick="return window.clickBtn()"/>

或いは

<asp:Button runat="server" ID="btn2" Text="テスト２" onclick="btn_Click" OnClientClick="return confirm('Are you sure?')"/>

<script type="text/javascript">

function clickBtn() {

// do something(validationなど)

return confirm("Are you sure?");

}

</script>

※OnClientClickに書いたJavaScriptコードの戻り値は必ずbool型である
