Spread for ASP.NET 表格控件在点击 Tab 键时,会在单元格之间切换焦点。顺序为 Cell[0,0],Cell[0,1],Cell[0,2].....Cell[0,5],Cell[1,0],Cell[1,1],Cell[1,2].....Cell[1,5]至最后一行最后一列,再返回至 Cell[0,0],如此往复循环。

本篇文章即阐述如何定制快捷键 Tab 点击事件,使焦点切换到其他控件。

C# 代码:

protected override void Render(HtmlTextWriter writer)
        {
            Table tb = this.FpSpread1.FindControl("viewPort") as Table;

            FpSpread1.Attributes.Add("onkeydown", "changefocus()");
            base.Render(writer);
        }
 
JS 代码:
<script type="text/javascript">
        function changefocus() {
            var button = this.document.getElementById("Button1");
            event.cancelBubble = true;
            return false;
            button.focus();

        }
    </script>
