グリッドビューと次のコードをJavaScriptで使用して新しい行を追加します。問題は、新しい行を追加するためにボタンをクリックすると行が追加されますが、以前の行データも含まれていてDBに保存されないということです。エラー "無効な番号"が生成されます。グリッドJavaScriptを使用した行の追加
<script type='text/javascript' language='javascript'>
function AddNewRecord()
{
var grd = document.getElementById('GridView1');
var tbod=grd.rows[0].parentNode;
var newRow=grd.rows[grd.rows.length - 1].cloneNode(true);
tbod.appendChild(newRow);
return false;
}
</script>
<asp:Button ID="Button2" runat="server" Text="Add Row" OnClientClick="return AddNewRecord();"/>
行を空にする必要があり、DBに保存する必要があります。
私はあなたがcloneNode(true)をグリッド
